Description:

This case relates to recording machines.

In particular, the invention deals with a machine for recording sales transactions in large stores such as department stores. The sales transaction is recorded by the machine on a sales slip or the like in the form of a printed record, and is also recorded on a tabulating card in the form of a punched coded record. The printed sales slip is usually given to the customer, while the punched card is retained in the store and subsequently used to control tabulating machines for tabulating the Information on the card.

Broadly, the invention has for its object to provide a novel, improved, machine for recording data pertaining to the article sold, to the clerk making the sale, and to the customer.

More specifically, an object of the invention is to provide novel card perforating means, and in such means to provide a novel punch pin guide and holder.

Another object is to provide a new key-controlled mechanism to enter an item in differentially operable means, such as item indicating elements, type members, or punching members. Still another object is to provide a novel form of item designation on a record medium, such as a slug, token, or check, and further to provide novel sensing means for reading the Item designation and transferring the value denoted by the designation to printing and punching means.

It is also an object to provide novel means for transferring the setting of punching means to other recording means, such as type wheels.

Other objects are to provide novel card eject3. ing means and novel positioning means for the sales slip.

Still other objects will appear in the following parts of the specification and from the drawings, in which: Fg. 1 is a plan section through the machine; Fgs. 2 to 6 are respectively sections along lines 2 to I of Fig. 1; Fig. 6a is a detail of an item wheel on a punch slide with the item wheel in section; Figs. 7 and 8 are sections along lines 1-7 and S-. of Fig. 1, respectively; ig. 9 is a section along lines 9-9 of Fig. 3; Fig. 10 is a section along lines IS-I1 of Fig. 1; Fig. 11 is a section along lines I --I I of Fig. 1; 5 Fig. 12 shows the tabulating cards punched in the machine; ig. 13 shows a sales slip on which a record is printed on the machine; SFig. 14 shows the customer's account number token; Fig. 15 shows the token representing the kind of article sold; Fig. 16 is a section along lines I6--i of Fig. 2; , Fig. 17 is a section along lines 11-11 of Fig. 2; Fig. 18 is a detail section taken along lines 18--18 of Fig. 1; Fig. 19 is a plan view of the punching mechanism of the machine with covering parts removed to expose interior mechanism; Fig. 20 is a detail, end, view of a punch slide, the punch carried thereby, a stripper bar, and part of the punch operating or pressure plate; Fig. 21 is a section on lines 21-21 of Fig. 20; 1 Fig. 22 is the timing diagram, and Fig. 23 Is a perspective view of the machine.

Following is the list of items which may be recorded for each article sold and the number of denominational orders assigned to each item. To each denominational order of an item, one card column is assigned.

Columns Price of one article-maximum $9999.99 -- 6 Transaction (cash take, cash carry, charge 20 take, charge' carry) -------------------- 1 Sales clerk.------------------------------ 2 Customer's account number-.------------- 6 Department to which the machine is assigned. 2 Kind of article-------------------------- 3 Date (day-2 cols., month-2 cols.)-------- 4 Total.------------------------------ 24 For illustration, the Hollerith code of punching a card is used. This code employs a single 30 perforation in one of the index point positions of a card column to designate a number. Thus numbers 9, 8, 7-- are designated by a single perforation in one of positions 9 to 0 of a card column (Fig. 12). 35 Briefly, the manner in which a sale is recorded is as follows: The clerk writes on sales slip 8 (Fig. 13) the name and address and other supplementary information relating to the sale.

For convenience, when the clerk writes on the slip the supplementary information referred to above, he may through a carbon sheet simultaneously inscribe this information on the blank portion of the first card to be punched. Each slip has space at the bottom to receive three line sa of printed data, each line relating to the sale of a separate one of several articles sold to one customer. Three is considered the usual maximum number of articles sold to one customer in one store department. If it is desired to record more than three sales on one slip, a longer sales slip may be provided.

For each printed line of data on the slip 8, one card T (Fig. 12) is punched. For three articles and three lines of printed data on one sales slip, three cards are punched, The date and department items are re-set in the machine. The kind of article and the customer's account number are represented respectively by tokens 0 and P (Figs. 14 and 15) bear- 6o ing identifying configurations. These tokens are inserted in the machine to control the setting of the punching and printing means for recording the kind of article and the customer's charge account number. A ten key board is operated to set up the amount or price, the kind of sale, and (clrk's number. A sales slip S is placed in printi;m position. These three steps, namely: token insertion, key operation, and sales slip positionjI ing, may be carried out in any order. After these three steps have been taken, the operator inserts a card T in the punch section. This insertion unlocks a manual actuator for a cycle of operation.

i. During this cycle, the card is punched and ejected and the first line s of data is printed on the sales slip. Should it be required to record more than one sale on the same slip, the slip is re-positioned, and the clerk sets up on the keys 2( a new amount and repeats the setting up of the keys for the kind of sale and clerk's number. A second card is inserted and a second cycle of the actuator etfected, resulting in punching the second card with the data of the second sale and in 2.3 printing the second line s on the sales slip.

A detail description of the machine follows: There are twenty-four punch slides or carriers (Figs. 1. 2. 3, and 19) one for each card column to be perforated. Each slide 10 is a narrow :w elongated bar slotted longitudinally to provide a card receiving slot I I (Figs. 6, 8, and 20). Each slide holds one punch pin 12. These punch pins are narrow, rectangular, in cross-section and perforate elongated rectangular holes in the card. 3; The punch pins must be smoothly and accurately mounted in their guiding holes and must be capable of moving accurately into their die holes.

It is difficult to bore and accurately machine and finish an internal, rectangular-shaped, elongat40 ed, punch guiding and receiving hole. The following means and method have been devised to overcome the above difficulty and to provide a smooth, accurate, guiding aperture and die hole for the punch.

4.5 Referring to Figs. 20 and 21, one side of the slide 10 is milled above and below slot I I with an open, angular, channel for accommodating half the cross-section of a punch pin 12. This open channel is accurately finished. A pair of plates 50 13 and 14 are also milled with open, angular, channels which are finished accurately and of dimensions to accommodate half the cross-section of the punch pin. Plate 13 is then welded to the slide above slot II and plate 14 welded to the ,5 slide below slot I with the channels in the plates and slide facing each other to form rectangular apertures above and below slot II for mounting and guiding a punch pin 12. The slide and plate 13 thus provide an upper punch holder and guide 60 and the slide and plate 14 provide a lower punch die.

The twenty-four slides or punch pin carriers II are arranged in parallel vertical planes and are slidably guided for horizontal movement within 6, their own planes by the slots of upper and lower comb bars 15 and by the surfaces of cross bars It to which the comb bars are secured. These cross bars are suitably held in rigid relation to the vertical frame plates 17 and II carried by 70 base plate II. The portions of the slides adjoining card-receiving slots II ride along comb bars 28 and 21 (see Fig. 6), which thereby assist combs II and bars II in restricting the carriers to slidable movement in their own planes. At the same 75 time, the confronting vertical sides of qcomb bar 20 and 21 serve as side guides for the card T to assist in locating the card properly when the card is inserted through slots II into punching position. The card is inserted lengthwise so that when in punching position, each of its columns is in the plane of one punch slide in position to be perforated by the punch mounted by the slide.

Each of the punch slides is separately adjustable lengthwise to one of ten positions to bring the punch 12 above one of the index point positions 9 to 0 of the card column in line with the slide.

The punch pin 12 is provided, near its upper end, with a transversely extending button 22 resting on a rail 23 and by this engagement, the rail normally holds the punch pin above card slot II and clear of the card in punching position. There is one rail 21 for each punch and the rails are arranged similarly to the punch slides so that during movement of a slide to a difflerential position, the punch moves between a pair of rails with its button 22 riding on top of one of the rails.

Rails 22 are secured at opposite ends between the locating teeth of a pair of transversely extending comb-bars 24 and 25. To the upper surfaces of the latter bars is secured a horizontal plate 21 which covers all the possible differential positions to which the twenty-four punches may be adjusted. Rails 22, bars 24 and 25, and plate 21 form a rigid punch operating assembly of which rails 22 constitute punch pin guiding and restor- 10 ing or stripping means and plate 26, the punch pin depressing means.

Bars 24 and 25 of the punch operating assembly are formed at each end with reduced circular portions seated in slots 27 (Pig. 5) of pairs of U levers 21 and 21, one pair at each side of the punch operating assembly. Levers 28 and 29 are pivotally connected to each other at their adjacent ends and pivoted intermediately on studs extending from the vertical side frames 17 and II. 40 Levers 21 are connected to depending links 31 (Figs. 5, 8, 19), formed at their lower ends with vertically elongated slots 31' (see particularly Pigs 5 and 8). A lever 12 is secured to the right hand end of a shaft 12 (as viewed in Fig. 1). 4 Shaft 33 is journaled by frame plates 17 and II, and at its left end, the shaft rigidly carries an arm 32' parallel to arm 32a of lever 32. Arms 32a and 32' are provided with pins 220 which extend Into slots 31' of links 1. At their outer ends, arms 32 and 32' have pins 121 extending into slots 322 formed in the sides of a bail 14 freely pivoted on a rod 3I carried by frames 17 and II. The sides of ball 34 are connected by cross bar 36 extending above all the slides 10 and adapted to engage in any of ten spaced notches 37 formed along the upper edge of each slide.

When the slides have been variously set in one of their ten differential positions, a cam 13 on cam shaft 39 (see Figs. 1, 3, and 5) acts on 4 arm 32b of lever 32, to rock the lever and its shaft 33 clockwise (Fig. 5). The first portion of the movement of shaft 33 causes arms 32a and 32' to rock bail 14 downwardly by camming coaction of pins 221 with th', upper, in- 6clined, portions of slots 322. The bail 34 is moved down to dotted line position, Fig. 5, and bar 31 is thereby moved into roughly alined notches 1I of the twenty-four slides I. When bar II is fully seated in these notches 37, it , alines the notches perfectly, and thereby locks all slides II accurately, with each slide occupying the exact differential position for which it had been adjusted. Subsequent to this action of bar 38, as shaft 38 continues its clockwise move- ., ment, pins $02 of arms 32a and 32' reach the lower ends of slots N1' and start to depress links 31, thereby rocking levers 2I clockwise and levers 28 anticlockwise (ig. 5) about pivots 30. As a result, levers 28 and 21 depress the punch operating assembly. Plate 26 of the assembly thereupon engages the heads of all twenty-four punches 12, and presses them through the selected index point positions of the card T In punching position.

While arms 32a and 32' are depressing the punch assembly, pins 321 which have cleared the inclined, upper portions of slots 322, travel along edges 323 of slots 322. These edges are concentric about shaft 33 when bail 34 is in dotted line position, Fig. 5, so that movement of pins 321 along these edges does not tend to move the bail, but serves to hold the bail in contact with limit stop pins 824.

When depression of the punch assembly, and, consequently, the punching of the card, is completed, a cam I3' on shaft 31, complementary to cam 38, acts on arm 32c of lever 32 to rock the latter counterclockwise (Fig. 5). During the 5 first part of this movement, pins 3$6 rise idly along slots 31' of links 31, and pins 321 move idly along edges 323 of bail 34. Before the pins 321 leave edges 323, pins 320 engage the upper ends of slots 31' and start elevating links 31.

10 This action of the links raises the punch operating assembly, and during the rise of the assembly. its restoring or stripping bars 23 engage buttons 22 of the punches to lift the latter, thus stripping the punches from the card and re., storing them to initial, raised, positions.

When the punch pins have been lifted clear of the card, pins 321 move into the inclined portions of slots 322 of bail 34 and start rocking the bail clockwise (Fig. 5). Thus, during the latter portion of the punch restoring action, ball 34 is rocked in a direction to release locking bar 36 from notches 31 of the slides, which are thus left free to be restored.

The timing of the above punching and locking actions will be more specifically given in the summary.

The manner in which slides II are moved lengthwise to be set differentially will now be explained. Each slide 10 is individually adjust0o able to set its punch 12 in one of ten differential positions 0 to 9. In the initial position of a slide, at the right end of its travel, as viewed in Figs. 6 and 8, the slide is in "0" position. From this latter position, it may move one to nine 65 steps to the left to set its punch 12 at successive positions "1" to "9" for perforating the corresponding 1 to 9 index point positions of a card column.

For convenence, in the following parts of the to description and in the drawings, the common reference character for similar elements may be suffixed by a distinguishing character to indicate the item to which the element relates. Distinguishing characters p, g, b, d, a, t, and c will 5 be used to denote respectively elements related to purchaser's account number, kind of goods, store department, date, amount or price of an article, kind of transaction, and clerk's number.

The arrangement of the several groups of slides is indicated in Fig. 1. "eading left to right In Fig. 1, there are six account number slides lip, two department slides lob, three kind of goods slides lIg, four date slides lid, six amount slides Ila, one transaction slide lOt, and two clerk num7 ber slides 10c.

Referring to Figs. 2 and 23, housing 40 of the machine has an opening at the top which is closed by a hinged door 41 located above cogtoothed wheels 42 (Figs. 1, 5, and 17). The four wheels 42 at the left correspond to the tens 10 and units of days and tens and units of months; the next three wheels 42 correspond to the kind of goods; the two following wheels correspond to the tens and units of the department number; and the last six correspond to the account 15 number. The door 41 is opened to provide access to the wheels 42 and at the beginning of each day, the operator manually sets day wheels 42. At the beginning of each month, the month wheels 42 are set. The department wheels 42 20 are set when the machine is assigned to record sales in a certain store department. Each of these wheels 42 has its teeth meshed with the teeth of type wheels 43 rotatably carried on a shaft 44 (see also Figs. 1, 5, and 17). 25 There are ten teeth on each type wheel 41, each tooth faced with a type legend 0 to 9 for printing these characters. When a wheel 42 is rotated, it rotates the meshed type wheel 43 to present the selected type at the printing line. 30 As shown in Fig. 17, each cog-toothed wheel 42 is carried by the left end of a nested shaft 45, which at the opposite end carries a wheel 46 (see also Figs. 1, 2, and 8) which is in mesh with rack teeth 47 formed along the upper edge 35 of a punch slide 10. The four date wheels 42 are thus geared to the four date slides IOd, the three kind of goods wheels 42 are geared to slides 10 , the department wheels 42 are geared to slides 10b, and the account wheels 42 are geared to 40 the six slides lip.

When the date and department wheels 42 are adjusted, through connected gear wheels 46 meshed with teeth 41 of the corresponding punch slides, they advance the latter slides to posi- 46 tion their punches for perforating the date and department columns of a card with the coded designations of the date and department items.

At the same time adjustment of the date and department wheels 42 sets the meshed type 50 wheels 43d and 43b (see Fig. 17) to print the date and department data.

The control of the account number and kind of goods slides 10p and g and the corresponding type wheels 43 by tokens P and Q will now be 55 explained.

Token setting Token P and G shown in Figs. 14 and 15 are preferably made of mel, though they may also 60 be made of any otbhr suitable material such as stiff paper, hard rubber, or composition material.

The token may also be referred to as a check, slug, or record member of which it is the equivalent.

To represent a uigit on the token, the latter is 66 formed with a vertical slot 48 proportional in length to the value of the digit. Thus "0" 13 represented by a slot of zero length or a solid portion of the token, "1" is represented by a short slot, "2" by a slot twice the length of the 70 "1" slot, and so on, the slot representing "9" being the longest. Each denominational order of the number designated by the token is represented in a different vertical portion of the token, as indicated in Figs. 14 and 15. Each token also 75 has a horizontal slot 41 near the bottom which is located eccentrically to the vertical center line of the token. Rigidly secured to frame plate II Is a frame I1 (see Figs. 1, 8, and 18) constructed I to provide a pair of separated pockets or receptacles II and 12 to respectively receive tokens P and 0. The lengths of the pockets are the same but their widths differ to correspond to the different widths of the two tokens. The top of housing 41 is cut out to permit insertion through the housing of the tokens into their respective pockets II and 52. When a token is fully Inserted in its pocket, its lower edge engages the top of a vertically slidable member 15 and depresses the latter against resistance of a spring 54. The spring connects member 53 to a pivoted latch lever 55 which has a lug 56 engaged with the advanced portion 1I of the front edge of member 5 when the latter is in upper position. There g are two such members 53 and companion latches II, one member and latch for each of pockets II and 52.

When a member is depressed by insertion of a token, its front edge portion 5T rides off lug I5 2s of the companion latch 5I permitting spring 54 to rock the latch anticlockwise (Fig. 8) to move the tooth I5 at its upper end into slot 43 of the token. This locks the token in correct position in its pocket.

a0 A token must be inserted with the front face, seen in Pigs. 14 and 15 towards the operator, positioned at the front of the machine (see Fig. 23) In order to bring the several columns or orders of designation slots into proper correlation 38 with the denominational order mechanism for reading these slots. By locating the locking slot 41 of a token off center, the operator is compelled to insert the token correctly otherwise the locking slot will be out of line with the tooth U of latch II and not in position to receive the locking tooth, in which case, as soon as the clerk relieved the pressure of his fingers on the token, member 53 would be raised by spring 14 to eject the token to inactive position.

4& The reading means for the token designations comprises the six account number punch slides I p and the three kind of goods punch slides IpI. These slides are formed at their forward. left hand ends (Fig. 8) with steps II arranged in echelon, one behind another, and at different distances from the longitudinal center line of the slide. The values corresponding to the different steps II are indicated alongside the steps. The extreme forward edge of the slide represents value 0.

Each of slides lip and 0, as well as the price, transaction, and clerk number slides I a, t, and c has a pin and slot connection at its rear end with the upper end of an arm 6I. The several arms 6I s0 are freely pivoted on a rod II carried between frame plates IT and II. Each arm II is separately connected to a spring 12. The springs urge the arms 60 and connected slides towards the left (Figs. 6 and 8). Initially, the arms can6s not move to the left because they are held back by engagement with a common bar 13 secured to the upper ends of arms 14 and 14', rotatably mounted on rod II (see also Fig. 3). The department and date slides are not connected to arms 6I, leaving room below the latter slides for locating arms 14 and 64'. The arm 64' is pinned to a link I6 (igs. 3 and 6) which is forked at the rear to slidably receive cam shaft 39. Link 5I has a follower roller 6I' riding on cam 66 of cam shaft 76 $3. In home positions of shaft 31 and cam 66, the roller 6I' is on a high dwell portion of the cam so that link 65, cross bar 63, and arms 6I are held at their right hand limits (Figs. 6 and 8). Slides IOp, g, a, t, and c connected to arms 61 are therefore initially maintained in "0" positions. When cam shaft 39 is rotated, counterclockwise, (Fig. 6) by means to be described further on, roller 6I' rides on the dwell portion of cam 66 and along a drop of the cam. Under the influence of springs 62, arms 60 move counter-clockwise (Fig. 6) and through engagement with ball bar 63 rock the latter in the same direction, causing link (6 to move to the left and its roller 15' to follow the contour of cam 16. Arms 61 move under the influence of their individual springs 62 and correspondingly move their connected slides until the latter are arrested differentially.

When the sale is for cash, a charge account token P is not inserted in the pocket II and similarly when it is not necessary to record the kind of merchandise, token G is not inserted in its pocket 12. When a token is not inserted, it is required to maintain its reading, punch, slides in their 0 positions. This is done as follows: In the absence of a token from its pocket, the associated member I5 is in upper position and its high or advanced portion 11 is engaging lug I5 of associated latch II to maintain the latter at its clockwise limit (Fig. 8). Latch 55 has a pin and slot connection with one of two bell crank levers 6T, there being one such lever for each latch.

The upper end of each lever 11 is formed with a transversely bent lug SI' extending across the group of token reading and punch slides IIg or p.

When a latch 55 is in clockwise, non-locking posdtion, through its connection with a lever 11 it holds the latter at its counterclockwise limit in which the stop lug 61' of the lever is in front of steps 11-1 of the group of associated punch slides lip or p. When so positioned, the stop lug 61' will arrest advance of the slides before they have moved more than a slight amount from their "0" positions. When the slides are later alined by bar I1, in the manner previously explained, they are set accurately in "0" positions. 43 In above manner, the absence of a token G from pocket 12 results in slides lig being held in their "0" positions, while the absence of a token P from pocket 1 causes slides I p to remain in "0" positions. s0 When a token is inserted, the associated latch II rocks anticlockwise (Fig. 8) to move its tooth 5I into notch 41 of the token, locking the latter in its pocket. As a latch rocks anticlockwise, It moves connected lever 61 clockwise to lower stop lug 61' out of the path of advance of the associated slides II. The latter may now move to read tokens P and 0.

Under the influence of the springs 12, arms 61 connected to slides lip and g move towards o0 tokens P and G in pockets II and 12. If a token has a solid "0" designating portion in front of a punch slide, the slide will be arrested when its front edge engages the token and will be set In "0" p6sition. If the token has a vertical, item as designating slot 41 equivalent to value 1, 2, 3-8, or 9 in front of the slide, the latter will move into the slot until the step 5I corresponding to the length of the slot engages the solid portion of the token above or below the slot. Thus, slots 48 of lengths 1, 2, 3, or 4 permit the slide to move 1, 2, 3, or 4 differential distances and arrest the slide when Its step 5--1, 2, 3, or 4 engages the part of the token above the slot. Slots 41 of lengths equivalent to 5, 6, 7, 8, or 9 arrest the 76 slide after the latter has moved 5 to 9 differential distances by engagement of steps I--- to 9 with the part of the token below the slot.

As the slides lp and g advance 1 to 9 differg ential distances, their punches 12 move to corresponding positions for punching the 1 to 9 index point positions of the account number and kind of goods columns of a tabulating card.

Further, as slides I p and a move forward to their differential positions under control of tokens P and 0, their rack teeth 41 coact with the meshed toothed wheels 41 of nested shafts 41 to turn these shafts correspondingly to the movement of the slides (see Figs. 1, 8, and 17). Cog18 toothed wheels 42 of these shafts 45 meshed with toothed type wheels 43p and g and set the latter for printing the account number and the kind of goods data corresponding to the setting of the slides lip and g.

2 During the final portion of the cycle of shaft 3I, ,cam ii acts on roller II' to move link II to the right which causes bail bar II to rock clockwise and pick up the variously positioned arms Ii and return them and their connected slides to their "0" positions. Slides lip and g thereby withdraw from tokens P and 0.

After slides lip and g are restored, a cam II (see Figs. 2, 3, 6, and 8) on shaft Ii rides past the lower, nose end of a lever ii and rocks the 80 latter clockwise. Lever I6 is connected to a link 11 which has a transversely extending pin 1I passing through alined slots 72 of the two latches 51. When lever Ii is rocked clockwise, through link 1l and pin TI it moves latches I in the same direction, releasing teeth 6I from slots 41 of the tokens. The retraction of the latches again places stop lugs IT' of levers 17 in front of the "9" stops Ia of slides lip and g. At the same time, springs 4 raise members IU to partially eject the tokens, which then protrude above the top of housing 48 to be conveniently removed by the operator.

The setting of the nine remaining punch slides; i. e., the amount, transaction, and clerk number punch slides Ila, t, and c and the corresponding 4. type wheels 43 is effected under control of a ten key keyboard, as will now be explained.

Ten key control There are ten keys 11, one for each of digits 0 ro to 9, as shown in Pigs. 1 and 23. These keys are mounted for vertical movement in the frame (see Pg. 4) and their stems are bent transversely, as shown in Fig. 2 to place their lower portions in parallel planes, side by side.

.i The disposition of the various key stems Is indicated at the bottom of Fig. 2 by the digital values to which the stems and keys correspond.

The lower ends of the key stems are located side by side, n horizontal, transverse alinement, and A) pivotally connected to the horizontal arms of bell crank levers 1I freely pivoted on a shaft 11. The vertical arms of levers 11 terminate In horizontally alined nose portions 11', each in front of one of ten stop fingers 11. These stop flngers are ;3 rigidly mounted on a shaft 16 and arranged within the same parallel, spaced, planes as levers 11, ua Indicated in Fig. 2. The fingers 11 are also rotatively displaced about their shaft 11 in the order indicated in Fig. 4. Accordingly, each fin70 ger 1I must move a different distance counterclockwise to reach the nose portion 16' within its plane.

The left end of shaft 11 (as viewed in Fig. 2) rigily carries a pinion go meshed with a wide 73 par drum II freely, rotatably carred by a shaft 12. Meshed with the top of drum II are nine toothed item indicating wheels 18. Each wheel 83 has ten teeth marked on their faces with indicating numerals 0 to 9 to be viewed through a sight opening 14 in the top of casing 40 (see Fig. 23).

Indicating wheels 83 are freely rotatably mounted on a shaft IS Journaled between frame plates II, 86, and 81 (see Fig. 2). The wheels I3 lie between the spaced sides of an H-shaped carriage 88 (see also Fig. 1). The sides of the carriage, at their front ends, are forked to slidably receive shaft I6. At their rear, the carriage sides are formed with threaded holes for coaction with the threaded portion of a shaft II. Carriage 3I is thus mounted on shafts II and *6 for slidable movement along the shafts to be advanced by rotation of shaft 8I.

Shaft 6I is rotatably journaled between frame plates 1., I6, and 1T. Rotation of shaft 6I through coaction of its threaded portion with the threaded apertures of the carriage effects movement of the carriage along shafts 6I and 6i.

As the carriage moves along these shafts, it slides wheels 83 along shaft I5. In the initial, home, positions of the parts. the carriage is at the extreme right of its travel (as viewed in Pigs. 1 and 2) and the item wheels I8 are entirely clear of all nine right hand punch slides Ila, t, and c. Each step of movement of the carriage to the left (Fig. 1) will move one of wheels I3 out of mesh with drum II and into mesh with rack teeth 41 of the unit order slide I c. Thus, the first step of movement of the carriage brings the first wheel 3i from the left (Figs. 1 and 2) clear of drum I and into mesh with teeth 41 of the right hand or unit order slide Ilc. The next step brings this first wheel 83 Into mesh' with the second or tens order slide IIe, and, at the same time, moves the second wheel U3 Into mesh with the units order slide IOc. In this manner, successive steps of travel of the carriage mesh the wheels II successively with the slides I a, t, and c. At the end of nine steps of transverse movement of carriage I8, all nine wheels 83 will have moved off drum 81 and into mesh with the nine slides I a. t, and c.

The transverse movement of carriage 88 is effected under control of keys 71. Each time a key 1 tIs depressed to enter a value in a wheel 5o 83, it causes a step of movement of carriage 6$.

Should the keys be depressed nine times to set up the aine wheels, then all nine wheels will be meshed with all nine slides I a, t, and c. There is one key operation required for the kind of 5 sale and two key settings for the clerk's number. When the price of the article is the maximum six denominational order figure, six key operations are required to set the price. Thus, the maximum possible settings are nine. How- 0o ever, the price may be less than a six order figure, for example, 8.50 in which case only three wheels lia will be set in addition to the setting of the one wheel lit and the two wheels lec, making a total of six settings, so that the last three o wheels will remain on drum 1 and will not be meshed with the slides. The other six, key-set, wheels It will be in mesh with the first six slides II from the right (Fig. 1). The three left hand slides If will not be in mesh with any of wheels 0 I3.

The setting of the slides I a, t, and c Is effected by their advance under control of wheels 8I meshed therewith, in a manner which will be brought out later. Unless provision were made f to the contrary, the slides Ila not meshed with wheels II would move unimpeded to their "9" positions, resulting in a wrong record of the price being punched and printed. To avoid this error, Sthe slides I a not in mesh with wheels 83 must be restrained from advancing beyond their "0" positions. For this purpose, the left leg of carriage 88 (as viewed in Figs. 1 and 2) is formed at its front end with a depending laterally extending finger II (see also Fig. 18) which lies In front of all nine slides I0a, t, and c when the carriage is in the initial, right hand position.

Finger 1I when In front of a slide blocks advance of the slide beyond its "0" position. When the carriage moves one step to the left to mesh the first wheel I8 with the first slide, then finger II moves away from the front of the first slide.

As successive steps of travel of the carriage are effected to successively mesh the wheels 83 with the slides, the blocking finger is displaced from in front of the successively meshed slides. At the end of nine steps of travel, all nine wheels $3 are meshed with slides II, and finger II is completely displaced to one side of the slides. Pinion II of shaft 71 and item indicating wheels 83 are both in mesh with gear drum II, and are of equal diameters so that the pinion and wheels move through equal arcs upon rotation of the drum. Indicating wheels 83 and shaft 71 thus have ten corresponding differential poslons.

These ten positions of a wheel 18 are defined by its indicating teeth I, I, 2-4 while the corresponding positions of shaft 71 are defined in the same order by stop fingers 71-I, 1, 2-1. Referring to Fig. 7, shaft 82, on which drum II is rotatably mounted, rigidly carries a pinion It (see also Figs. 1 and 2) meshed with a gear I3 rotatably mounted on a shaft 14 carried by the frame plates I6 and 81. Rigid with the side of gear 13 is a pinion 1I meshed wth a gear sector N which is freely pivoted on a stud 61 carried by frame plate II. A spring U6 connected to gear sector 12 urges the gear sector clockwise (Fig. 7). Sector 96 has a travel of about 40* and the ratio of gearing 6I, II, 13, IS, II, and I8 is such that the full stroke movement of sector N it capable of producing eleven revolutions of wheels I2, more than sufficient to move each of the nine indicating wheels 3I 0 through an entire revolution.

Shaft 82 has fixed to it an arm II adjacent the side of drum II. In the initial position of the parts, arm II is engaging the free end of a pawl III pivoted to the side of drum II and urged 56 by a spring II8' towards arm II and Into limiting enagement with a pin III extending from the side of the drum. When shaft 12 is rotated clockwise, its arm It coacts with pawl III to rotate drum II in' the same direction. During the counterclockwise, restoring, revolutions of shaft IS, its arm II will withdraw from pawl III and at each revolution, the arm will ride past the pawl, spring III' yielding to permit the pawl to be cammed aside. Thus, arm II and pawl 10l provide a one-way, clockwise, driving connection between shaft 12 and drum II. Drum SI is never moved counterclockwise, as will later be brought out, but is moved only clockwlse by the aforesaid one-way driving connetion, and under control of pinion II with which it is meshed.

Drum II cannot move clockwise unless pinion 8I and its shaft 11 are free to rotate counterclockwise (Figs. 4 and 16). Shaft 1 fixedly carries a disk 112 (see Figs. 1, 2, and 16) which has ten teeth II, one of which is normally in engagement with the nose end 104' of a bell crank lever 104. Teeth 163 are spaced correspondingly to the spacing of stop fingers 71 about shaft 17.

When nose end 104' is engaged with a tooth 1I3, shaft 71 cannot rotate counterclockwise and drum II is not free to be rotated clockwise.

Lever 104 is rotatably carried by shaft 17 and is urged counterclockwise (Figs. 4 and 16) to engage its nose end 104' with a tooth of disk 102. The horizontal arm of lever 114 is bent angularly to provide a transverse lug 6I extending under the left hand arm of a bail 107 freely pivoted on shaft 7T.

The cross bar 107' of the ball underlies the lower edges of the horizontal arms of all ten bell ]5 crank levers 16 which are pinned to the ten keys 16 (see Fig. 4). Spring III acting through lever 104 and its lug 101 urges bail bar 107' upwardly to maintain contact with the lower edges of the horizontal arms of levers 17 and In so doing, the spring helps to force keys 71 to their upper positions. The keys are additionally urged to upper positions by springs 10 acting on levers 71.

Riveted to the left side of bail 101 is a plate 10I having two sets of reversely inclined ratchet teeth 10. Each set of teeth III coacts with one of the end teeth III of the full stroke toggle pawl I 2. A spring II acting on the pawl holds it set In either clockwise or counterclockwise position. When any of the ten keys 75 is depressed, it rocks the connected lever 71 clockwise (Fig. 4) which depresses common bail 107 and the toothed member 109 carried by the bail. Once depression of a key is begun, the key cannot rise again until the full down stroke has been completed due to restraining coaction between !,he lower tooth II of pawl I12 with the lower set "f teeth 11 I of member I0M. When a full down stro- ofc the key Is made, then upper shoulder i* of merm- 4 ber III strikes projection IIS of P-, 2 "' rocks the pawl counterclockwise. When ;ti operator releases pressure on the depressed key springs III and 618 combine to forcr the k:y Its upper position and during restoration of t 6l 5 key, upper tooth III of pawl 112 engages with the upper set of ratchet teeth III of member 106 to prevent depression of the key before it has finished its up stroke. Just before the end of the tip stroke of the key and of ball 107, the lower shoulder 114 of member I$1 strikes lug i II of the pawl and causes return of the pawl to initial clockwise position.

At the beginning, all nine item indicating wheels 83 are sitting on top of drum II, each 5; wheel at zero position, and correspondingly shaft 7S Is at zero position with detent 104' engaging a tooth 103 of disk 102 to prevent rotation of the shaft 1I, drum I1, and wheels 83 under the influence of spring II. Co When any of the keys is depressed, It actuates the connected lever 7I to place the nose end IS' of the lever in the path of rotation of the stop finger 78 which is in the same plane. Further, when the lever 16 is actuated, it acts on bar !01' ;5 to rock ball 11 clockwise (Fig. 4). The ba'i in turn acts on lug 101 of bell crank lever IC : to rock the lever clockwise, opposed by the pull of spring 101. As a result, detent end 114' of lever 104 is released from the teeth of disk 102. There 71 is nothing now to restrain rotation by spring actuator II of shaft 7I, its pinion I0, drum II, wheels II, gears 12, II, I, and II. Shaft '9 and the other elements of the above gear train, when released by detent 104', rotate under the influence 76 of spring Ii until the nose end T6' of the lever 16 connected to the depressed key is engaged by the associated stop finger 18. On the up stroke of the key, connected lever 16 returns in a coun* terclockwise direction (Fig. 4), withdrawing its nose end 1l' from the stop finger 18 engaged with the nose end and releasing shaft 13 for a supplementary rotation counterclockwise. During the upstroke of the key, spring 186 also restores lever 164 to replace its detent end in the path of rotation of a tooth 103 of disk 112, thus arresting the supplementary movement of shaft 1i. The total of the initial and supplementary movements of shaft 11 displaces the shaft through an even mul18 tiple of its differential positions. Correspondinuly, item wheels 83 will have moved through the same number of their differential positions.

Por example, depression of the "0" key releases common detent 114' from shaft T1 and moves "0" lever 1S to place Its nose end 11' in the path of the "0" tooth 13. At "0" position of the parts, "0" tooth 18 is below "0" nose end 16' so that shaft 11 makes almost a full revolution before the "0" tooth engages the coacting nose end 71'. 26 Then during rise of the "0" key, the "0" nose end TS' Is withdrawn from the "0" tooth 18 and common detent 114' moves between a pair of teeth 183 of disk 112. Shaft 13 now rotates an additional amount until arrested by engagement of a tooth 13i with detent 104'. The total movement of the shaft will be through one complete revolution at the end of which the "0" stop finger 18 Will again be in the position from which it started.

Cbrrespondingly, item wheels 83 meshed with drum I$1 will have moved through one revolution from "0" position to "0" position.

If with the parts in "0" position, the "1" key is depressed, then "1" lever 11 will be moved forward and common detent 184" released from restraint on shaft 19. Shaft 11 will first rotate until the "1" finger 11 engages "1" nose end I3'; then on the upstroke of the key, the shaft will be released for a further, slight, movement until arrested by detent 104'. Similarly, depression of the other keys will cause movement of the shaft from "0" position through the number of positions indicated by the depressed key.

The reason for effecting part of the movement of the shaft upon the down stroke and the remainder of the movement upon the up stroke of the key is to correctly time the release and arrest of shaft 19 by the oppositely moving nose end 10' and detent 114' and to provide clearance between detent 104' and teeth 13i when the detent M returns to restraining position.

If the shaft 11 were to move the complete differential distance upon the down stroke of the key, at the end of this movement, a tooth 13i would be exactly in line with detent 184'. Then 80 when the active nose end 16' released the stop inger engaged therewith, shaft 10 might rotate slightly before detent 1I4' could move above the aimned stop surface of the tooth 113 in front of the detent. As a result, the detent would fall U to engage the proper tooth I3N and shaft 19 would move an additional step. Further, if during return of the detent end 104', it were exactly In line with a tooth III, then it might strike the edge of the tooth and be unable to move above 1T the tooth. By moving shaft 11 through less.than Its full differential distance upon the down stroke of the key, detent 104' can move with complete clearness above the surface of the tooth III below It and the remainder of the differential movement can be conveniently effected to bring the tooth and detent into engagement.

When shaft 13 and Item wheels 83 on drum II have been moved by depression of a key ?I to a differential position other than "0", the follow- # ing key depression will not cause movement of the shaft and item wheels through the same number of steps as represented by the number on the latter key, but through such a number of steps as will bring the shaft and wheels to the differential position corresponding to the depressed key. For example, if shbat 11 is in "1" position, its "1" stop finger 1I will be at the point initially occupied by the "0" finger. Now, If a "1" key 15 is depressed, shaft 19 will make a full rotation, in the same manner as described above in connection with the "0" setting, and under the successive control of the "1" nose end 71' and the common detent 104' the abaft will again be in "1" position. If the shaft is in "1" position and a "'O key 7I is operated, then the shaft will move one step before it is completely arrested and the "2" fnger 1S will be in the position in which the "0" finger 18 is shown in Fig. 4. This latter position may be referred to as the reference position. If shaft 13 has finger 18-I at the reference position, then depression of the "4" key 11 will cause movement of the shaft through six steps to bring the "4" finger 11 to the reference position. Similarly, no matter in what differential position shaft 1 may be, depression of a key .15 will cause the shaft to move through the number of steps required to bring it to the position represented by the depressed key. Correspondingly, those item wheels 83 still meshed with drum II will move from any differential position they occupy to the new position represented by the key last depressed. For example, if a wheel 83 on drum 81 reads "4" and the "6" key 11 is depressed, this wheel 83 will move two differential steps to read "6".

As explained above depression of a key differentially sets all the wheels 83 meshing with drum I I to the common position represented by the key.

Thus, initially, all nine wheels are on the drum and operation of key 15-S. for example, will set the nine wheels similarly, each to a "6" position.

In addition to setting wheels 13, operation of any of keys 16 controls an escapement mechanism to effect rotation of screw shaft 33 to an extent such as to move carriage 88 and wheels 3I one step to the left, as viewed in Figs. 1 and 2, thereby removing one wheel 83 from drum II and meshing this wheel with the right hand end slide lSc. Referring particularly to Figs. 1 and 11, the escapement-controlled means for rotating screw shaft II comprises gear sector 121 pivoted on stud 121 carried by frame plate 1T. A spring 122 connected to/sector 121 urges It clockwise (Fig. 11) to rotate gear train 123, 124, 125. and 121. Gear 121 meshes with a pinion 121 fixed to screw shaft ii. Also meshed with gear 126 is a pinion t12 (Figs. 1, 2, and 11) freely, rotatably, carried by shaft 11. Rigid with pin- G1 ion 128 are two teeth I29 and 131 spaced apart along shaft 11 and having their radial, stop surfaces extending along the same diametral line and 180* apart.

Stop tooth 121 is normally in engagement with 7 the nose end of a detent arm 131 rotatably carried by the left end of shaft 11 (see Fig. 1). Adjacent arm 1)1, shaft 11 has rigidly fastened to it another detent arm 132 located in the plane of tooth 13. The nose end of arm 132 is initially In front of, slightly below, and remote from stop tooth 13. A lug 133 on arm 132 is held engaged with a stud 134 on arm 11I by a spring 131 connected to the stud 134 and to the frame.

Referring to Pig. 4, when a key 15 It depresed to set wheels 83, it rocks the connected lever 1t which In turn rocks common ball 11 clockwise. Underlying the left side of ball 11 (as viewed in Fig. 2) is the transversely bent lug 188' formed at the free end of an arm 138 pinned to shaft 11. Thus, when bail I1 rocks clockwise due to depression of a key, arm 138 and Its shaft 11 are rocked similarly. Since detent arm 132 is pinned to shaft 11, It will also be moved clockwise (Pig. 11) to a position directly underlying stop tooth 130 and in the path of counterclockwise rotation of the latter tooth. At the same time, as arm 132 moves to the right, Its lug 13 acts on stud 14 of arm 131 to move the latter, 90 against the pull of spring 135, in the same direction, thereby displacing the nose end of arm III from engagement with stop tooth 121.

The gear train comprising elements 121, 123, 114, 11, It1, 121, and t12 is now free to be S rotated by the power of spring 122. Pinion 128 rotates a slight distance anticlockwise bringing Its tooth 12t above and clear of the nose end of detent arm 131 and its tooth 13I into engagement with the top of detent arm 132. During this rotation of pinion 128, gear 121 rotates pinion 121 and its shaft 81 through a small angle, causing movement of the item wheels 83 on drum 81 slightly to the left (Pigs. 1 and 2), but not to such an extent as to demesh the left 3a hand one of the latter wheels from the drum.

The above, initial, escape action of the wheels 8S is the result of depression of a key 11. As previously explained, the depression of a key 11 also causes an initial setting operation to partially set the wheels 83 on the drum to the reading represented by the depressed key. During the, up stroke of a key, wheels U are given the final portion of the setting operation to complete their setting to the differential position selected by the key. Also, during the upward, return, stroke of the key, the escapement means operates to efect a supplementary rotation of shaft 38 to complete the lateral step of movement of carriage 88 and wheels 83. The completion of the setr, ting of wheels 83 overlaps the early portion of the supplementary escape movement of carriage 88 and takes place before the left hand wheel 83 meshed with drum 81 has left the drum. In brief, the relation of the parts and their timing ,. are such that upon the down stroke of a key, all but a minor portion of the setting movement of the item wheels is carried out while only a slight portion of the escape step is effected, and upon the up stroke of the key, the slight, fraco tional, remainder of the wheel setting is completed and the major portion of the escape step takes place.

During the rise of the key, ball 11 moves counterclockwise (Fig. 4), permitting spring 135 a', to rock detent arm 131 to the left to position the nose end of the arm in the path of counterclockwise movement of associated stop tooth 12t which at this time is above the nose of arm 13I1 due to the initial escape movement. When arm 131 Ls rocked to the left (ig. 11) by spring 113, through coaction of stud 134 and lug 183, arm I1 is similarly moved to the left, thereby withdrawing its nose end from engagement with tooth 13. This leaves pinion 128 free to rotate counterclockwise 7g under the influence of spring 122 until tooth t12 engages the noe of arm III. The parts of the escape means are then in Initial position, shown in Fig. 11 and pinion 128 has completed a revolution. As a result of the supplementary, final, escape movement, gear 12I has rotated screw a shaft IS to complete the lateral step of movement of carriage U, and to thereby entirely remove from drum II, the left hand one of the group wheels I3 meshed with the drum at the begnning of the lat key operation. In above manner, each time a key Is operated, it causes all those wheels 3 which are still meshed with drum SI to be differentially and commanly set to the position represented by the key and ao causes escapement mechanism to shift in the wheels laterally to move the left hand one of these wheels off the drum and onto the first units order, aBde Ile. In nine key operations, wheels 3 will be successively displaced to the left until they are al removed from I1 and in mesh with 3i the nine slides IK , , nd c. Similarly, one to eight key operations will move the same number of wheels U8 off drum II and on to the same number of slides II.

The reason for effecting the escapement move- U ment In two parts and under control of two detents Is because the length of time during which the operator holds a key depressed is Indeterminate. If only one detent and escapement tooth were provided, there would be no assurance that 3o the detent after release by the depression of the key would be restored In time to arrest the tooth when it had made one revolution. By utilizing the two detents 131 and 12, at least one is always in position to engage the coacting tooth 3 121 or 13I and regardless of the length of time during which a key is held down, the escapement mechanism will move only one full step for each reciprocation of a key.

As an example of the setting and escape operatlons, assume the price of an article is 8.50, the kind of sale is "charge send" represented by code number 4, and that the clerk's number Is 11.

Initially shaft Tl I in "0" position and the nine wheels 8 are on drum SI. The operator first 4 depresses key 151-, causing release of detent end 14' of lever 14 from disk 182. Shaft 1 moves almost eight differential steps from its "0" poation until arrested by engagement of stop finger 1-" with the nose end of the vertical arm of 5s lever 11-. and drum II and the nine wheels 83 move synchronously with shaft 1. Depression of key 11- also caused release of detent 131 from tooth 12I of pinion 12i, and simultaneously caused movement of detent 132 into the path of 5. movement of tooth 13 of the pinion. Spring 122 acts, upon release of pinion 128, to rotate the latter a slight amount until tooth 13I engages detent 182. This initial rotation of pinion 128 Is accompanied by corresponding rotational move- m ments of gear 12 and pinion 121. Shaft sI of the latter pinion coacts with carriage 18 to shift the latter and the nine wheels 83 slightly to the left.

When the operator releases key 1-I4, lever 11-8 rocks counterclockwise (Ig. 4), withdraw- * Ing its nose end from stop finger 11--; simultaneously spring I1I moves detent end 114' above a tooth 1I3 of disk 102. Shaft 11 rotates a slight amount, completing its eight step movement from T0 "0" position, and is then arrested by engagement of the detent end 134' with the tooth 183. During the latter rotation of shaft 13, the nine wheels 83 on drum I are correspondingly rotated and now set to read "8". is During rise of key 1--8, detent 132 Is displaced from tooth 130 of pinion 128, and detent 131 is interposed in the path of rotation of tooth 129 of this pinion. Spring 122 acts now to rotate pinion 128 through the greater part of a revolution until tooth 129 engages detent 131, and the pinion is thus arrested in initial position. During the latter rotation of pinion 128, gear 121 rotates pinion 121 and its shaft 88 to shift carriage 88 and wheels 83 to the left for the major part of their escapement step. The differential setting of wheels 83 to their "8" positions is completed during the first part of this latter escape step, and then as the escapement continues, the first 1s wheel 83 from the left (Figs. 1 and 2) moves off drum 81 and onto unit slide 1Oc. At the end of the escapement step, this first. wheel 83 reads "8" through sight opening 14 (Fig. 23). The other eight wheels are still on the drum.

0g The clerk now depresses key 15-7 ; shaft 11 rotates from its "8" setting an amount just short of seven steps before being arrested by engagement of stop finger 18-I with lever 1T--. Upon the up stroke of the key, shaft 19 covers the reS2 malning distance to its "5" position where it is arrested by detent 184'.

The eight wheels which at the beginning of the operation of key 15-- were on drum II are set now at "5". The reciprocation of the key o effected escape of the carriage 39, bringing the left hand one of the latter eight wheels off drum I1 and onto unit slide 1c, where its reading "5" is visible through window 14. The left hand one of all nine wheels 13 had been set during the first U key operation to "8" and demeshed from drum SI, so that it was not affected by the rotation of drum $I which took place upon the second key operation and remains at "8". The second escape operation of carriage 88 moves the latter wheel 83 onto the tens order slide 1c which is the second one from the right (as viewed in Fig. 1.) In the same manner, keys 1I are successively depressed to set up 0, 4, and 11 on wheels 63.

At the end of the six required key operations, the g first wheel from the left will read 8, and be in mesh with units dollar order slide ISa, the next wheel will read 5 and mesh with dimes order slide 11a, the third wheel will read 0 and mesh with the cents slide 18a, the forth wheel will SN stand at 4 and mesh with transaction slide 18t, and the fifth and sixth wheels will each read 1 and be in mesh with tens and units slides 10c.

Through sight window 84, the reading 850 will appear under a suitable heading (not shown) desI noting "amount", "4" will appear under a heading (not shown) denoting "kind of sale", and "11" will appear below a heading (not shown) indicating "clerk." The last three wheels 83 will remain on drum d0 81, each wheel reading "1" as a result of the last key setting. Also, the last three higher order slides I 0a, namely, the thousands, hundreds, and tens of dollar orders slides will be out of mesh with any of wheels 83. The abutment 10. proM vided on carriage 88 will be in front of these last three slides 10a, as has been explained before.

During the cycle of shaft 39, which is initiated by the operator subsequent to the setting operations, the item wheels 83 remaining on drum 81 are set to "O". For this purpose, a gear 136 at the right end of cam shaft 39 (as viewed in Figs. 1 and 3) carries at one side a cam piece 131 (see also Fig. 10). During the initial portion of revo7T lution of shaft 39, cam piece 11 rides past the free end of an arm 138 fixed to one end of a shaft 138', and thereby rocks shaft 139 clockwise (Fig. 10). The opposite end of shaft 131 has fast to it an upright arm 140 connected by a link 141 to an arm 142 loosely mounted on shaft 11 (see Figs. 4 and 16). Arm 142 Is in the same vertical plane as a special zero stop finger 18'-- secured to shaft 10 at the left of the ten-key controlled fingers 18 and disposed in the same relation to arm 142 as that of the key-controlled "0" finger 18 to nose end 16' of "0" lever 16. Arm 142 has a lug 143 held engaged with pin 144 on detent arm 184 by spring I 6.

When cam lug 131 rocks shaft 139 clockwise, the shaft, through arm 140 and link 141, rocks arm 142 in the same direction. Arm 142, through coaction of lug 143 and stud 144, displaces detent 184' from the teeth 103 of disk 102, permitting spring 88 (Fig. 7) to rotate gear drum 81 and the item wheels 83 thereon until special "0" finger 11'-4 abuts the nose end of arm 142.

Cam piece 187 holds arm 139' depressed long enough for shaft "1T to make substantially one revolution. When the cam lug rides off the end of arm 139', then spring 106 restores detent arm 164 which in turn restores arm 142. Arm 142 thereupon releases finger 18' and shaft 18 completes its movement to "0" position, where it is stopped by detent 104' engaging a tooth 103 of disk 112. Shaft 19, drum 81, and the item wheels 83 on the drum are now at "0" positions.

Subsequent to the above described setting of the wheels on drum II to "O", the spring actuator Is of drum I is retensloned. This is done by a cam 145 (see Figs. 1, 3, and 7) fast to cam shaft 3I. During the revolution of shaft 31, cam 141 acts on roller 146 of gear sector 9I to rock the sector counterclockwise, thereby retensioning spring 98. As sector 1I moves counterclockwise through gears 13 and 84, it rotates pinion 92 and its shaft 82 in the same direction. During the counterclockwise revolutions of shaft 82, arm 99 on the shaft rides over pawl 100 without restraint due to yielding of spring 100'. Any tendency of drum SI to rotate counterclockwise during such movement of shaft I2 is effectively prevented for thesfollowing reasons: Counterclockwise motion of drum SI would rotate shaft 11 clockwise (Pig. 7) and the latter movement would be effectively stopped by engagement of the top of detent end 184' with the tooth 183 directly above it (see Fig. 16) before shaft 11 could move one differential step. Further, if any item wheels 83 are still on drum 81, they are at zero positions and would also prevent tendency of the drum to rotate counterclockwise. This is because each wheel 83 has a home or zero position dog 14i (see Fig. 6a) which when the wheel Is in zero position, is engaged with a flat shoulder 141 formed along shaft I8 of the wheels (see also Fig. 1).

For drum 81 to rotate counterclockwise requires clockwise movement of the wheels I3 on the drum, which are now at "0" position and cannot move clockwise because of dogs 14M abutting M shoulder 149 of shaft 11. As a result, drum SI cannot move counterclockwise. Nor can the drum move clockwise, unless released by disengagement of detent 114' from teeth 180 of disk 192, which occurs only under control of keys 71 or cam 131.

Drum I has three times as many teeth as an item wheel 11 etnd when the latter is in "0" position, pawl II, on the drum may be in either of three "0" positions, the one shown in Fig. 7, and 15 two others successively located one-third of a revolution apart. When restoring cam 14I leaves roller 146, arm 99 is in the position shown in Fig. 7. If pawl 100 is also in this position, then the pawl prevents clockwise rotation of arm 99.

If pawl 100 is in either of the two successive positions further on in a clockwise direction, then spring $9 moves arm 9I clockwise 120* or 240" until it engages pawl I19. The parts 19 and 99 are now in required relation for effecting clockwise rotation of drum SI during the next series of key-setting operations. The maximum possible number of rotations of item wheels 83 to be imparted by drum I1 is nine. The ratio of gearing and the extent of movement of sector 19 are such as to be capable of rotating drum II through three and two thirds revolutions, providing therefore a surplus of two revolutions.

Accordingly, even if after restoration of arm 1I, It has moved ahead under the force of spring 93 through two-thirds of a revolution, its remaining capacity for effecting three more revolutions of drum I1 is sumcient to furnish the maximum of nine revolutions of the nine Item wheels 83.

Those item wheels 83 which have moved off drum 81 and into mesh with punch slides Ia, t, and c control the setting of the slides to positions corresponding to the settings of the Item wheels. This is done as follows: Referring to Fig. 6, it has been explained that slides I a, t, and c, are connected to arms 11 which are urged by individual springs 12 towards the left to move the connected slides in the same direction. This movement is normally prevented by cross bar 63 engaging the front of arms 61. When the cross bar is permitted by cam 96 to move to the left. then springs 62 act on arms II to move them in the same direction. The arms In turn move slides ISa, 11t, and 10e towards the left and through coaction of teeth 41 on these slides with the teeth of wheels 83 meshed with the slides, the wheels are rotated clockwise. The extent of this rotation is determined by engagement of the 46 zero position dogs 148 of the wheels with shoulder 149 of shaft S5 (see Fig. 6a). Slides ISa, t, and c thus move differential distances to the left until arrested by the zeroizing of the item wheel 83 meshed with the slides; and as a result, their punch pins 12 are positioned to perforate card T according to the Itams set up by keys 17. Any of slides Ila which have not been meshed with wheels I8 by the key operations, as when the amount 8.50 is set up, are arrested before they move out of their "0" positions by the carriage abutment SO which is located in front of these slides.

Also meshed with teeth 41 of slides I a, t, and c are pinions II carried by the right hand ends of nested shafts 151 (as viewed in Figs. 1 and 17), the opposite ends of which carry type wheels 43a, t, and c. Thus, when slides I1a, t, and c advance to differential positions under control of wheels I8, the slides rotate pinions 1II to set type wheels 41a, t, and e to print the items set up by keys 71.

Those higher order slides I a (at the left in Fig. 1) which have not been set under control of wheels 83 but have been retained in "0" pos1tlons by abutment 09 do not rotate their pinions IS0 and therefore the corresponding higher order typewheels 43a also remain In zero positions. The highest order wheel 43a has no "0" type lug since it is not necessary to print "0" In the highest 76 order of the amount while the remaining wheels 43a have "0" type to print "0" in an intermediate order of the amount item.

Subsequent to the setting of slides 10a, t, and c to differential positions, alining bar 36 moves into notches to exactly aline the slides, and the type wheels geared thereto, in their various differential positions.

When slides 10a, t, and c have been set under control of wheels 13, the latter are at zero positions, and may be returned to drum 81. To restore these wheels to the drum, carriage 88 must be moved to the right (Fig. 1) by rotation of threaded shaft S1 in a clockwise direction (Fig. 11). This Is done by a cam 158 on shaft 39 (see Figs. 1, 3, and 11). During the cycle of shaft 3I, cam III engages follower roller 159 on gear sector 12t to rock the latter counterclockwise (Fig. 11). In so doing, spring 122 of the escapement mechanism is retensioned. As gear sector 121 moves counterclockwise, it causes clockwise movement of pinions 127 and 128. Clockwise rotation of pinion 12 is not prevented by detent arm III, since escapement tooth 129 merely cams the nose on this arm outwardly, as permitted by yielding of spring 135. Clockwise rotation of pinion 127 moves Its shaft *I in the same direction. This rotation of shaft II, through coaction of its threaded portion with carriage 99, moves the carriage and all nine wheels 13 mounted between the sides of the carriage towards the right (Fig. 1). At the end of this movement, the nine wheels 83 are entirely demeshed from slides 0a, t, and c and again meshed with drum 91 in their initial positions.

During return of the wheels 83 to drum 81, it is desirable to relieve the pressure between shoulder 149 of shaft 8I and the dogs 148 of the wheels. Further, the teeth of the wheels may not be in perfect alinement with the teeth of drum I and if dogs 148 were firmly engaged with shoulder 149 of shaft 85, the wheels would be unable to rotate slightly so as to bring their teeth into line with the teeth of drum 8I and as a result, the wheels would be unable to return to the drum. The left ends of the teeth of drum I1 are rounded to facilitate meshing of wheels 18 therewith when the wheels slide back onto the drum. If the wheels are free to rotate, then if their teeth are not exactly alined with the drum teeth, the rounded ends of the latter teeth cam against the teeth of wheels 83 to rotate the wheels slightly until their teeth are in alinement.

To permit this alining rotation of wheels 83 and to relieve the pressure between dogs 148 and shoulder 140, shaft IS is rocked clockwise (Fig. 4) under control of a cam 1I0 (Figs. 1, 3, and 4) on shaft 31. The cam is engaged by a roller III at the right end of a link 112 slidably guided at said end by shaft 39 and connected at the opposite end to a crank arm 153 depending from 00 shaft II.

The high dwell portion of cam II0 rides off roller III after slides II have been locked in place by alining bar 36. A spring 164 thereupon moves link S12 to the left (Fig. 4), rocking arm III and shaft 18 clockwise. As a result, shoulder 149 of shaft 8I is moved away from zero pawls 148 of wheels 83 (see Fig. 6a), thereby preventing binding between the wheels I3, shaft I5, and drum II while the wheels are being returned into mesh with the drum. At the beginning of the next cycle of shaft 31, cam I60 positively restores shaft 1I and shoulder 141 to their normal positions.

Following the completion of the punching op- Teration and upon restoration of the punch pins, alining bar 36 unlocks slides II, as previously explained. Slides I Op and g, when unlocked by bar 30, are still restrained from advancing further by their engagement with tokens P and 0. Slides Iga, t, and c, however, when released by bar 31, tend to advance under the influence of springactuated arms 60. To avoid this unnecessary advance of bars 10a, t, and c, their right hand portions (Fig. 6) are formed along their lower edges with ratchet teeth 165 for coacting with bell crank check pawls I11 rotatably carried by a rod 161 on which is also pivoted a yoke 18. The yoke carries a pin 189 between its sides acting to limit counterclockwise movement (fig. 6) of check pawls i8o by springs 111. One side of yoke 188 has a pin and slot connection with a lever 112 which has a follower 113 engaging a cam 114 on cam shaft 38 (see also Pig. 3). While the slide aliner bar 38 is still locking slides II in their differential positions, cam 174 rocks lever 112 clockwise (Fig. 6) against resistance of a spring ITS. Lever 112 thereby moves yoke III counterclockwise, and springs T16 cause check pawls 166 to follow and engage teeth 18I of slides Ila, t, and c. This prevents unnecessary advance of the latter slides when alining bar 38 subsequently unlocks the slides.

After the punching operation, cam 68 on shaft 30 acts on follower 65' of link 80 to rock arms 84 and 64' clockwise, causing bar 63 to restore arms 60 and slides 10. Restoration of the slides takes place while the check pawls I88 are still engaged with teeth (II of slides I a, t, and o. After complete restoration of the slides, cam 114 permits springs 175 to rock lever 112 ant!clockwise (Fig. 6), and yoke 188 moves clockwise, causing its pin 189 to withdraw check pawls II6 from teeth III.

The means cooperating with printing wheels 43 to effect an imprint on sales slip 8 will now be explained.

Printing means Slip S is placed face upward on a printing table 45 Il (see Figs. 1 , , 5, and 23) which is formed at the sides and at the rear with upwardly extending retaining lips III. Table I8 tIs removably carried on the horizontal, top, flanges of an open box-like support 183 and secured to the rear flange 183 (see Fig. 1) by screws 184.

Each of the sides 186 and III' of support 181 is formed with a pair of elongated slots 18I for receiving guide studs 187 extending from frame plates IT and 11' (Figs. 1, 2, 5); and by this 51 means, support 183 and table III are mounted for horizontal, slidable movement. A spring I8I (Fig. 1), connected at one end to pin III extending from frame plate I1 and at the other end to support 182, constantly urges the table and GO support forwardly towards type wheels 43. The limiting forward position of the table is determined by the engagement of guide studs Il1 with the rear ends of slots IO8 of the support. In this position of the table, the slip 8 thereon has 85 Its top or first line a in printing position below type wheels 431, Side 185 of table support 182 is formed at its right end (Fig. 5) with a pair of notches 10 followed by an inclined edge 100'. These notches 7o and the inclined edge selectively coact with the left end of a lever 112 urged clockwise (Fig. 5) by a spring 193.

An index or pointer 184 extending from the left side of table 180 (Fig. 23) coacts with figures 1, 2, 3 marked on a plate Ill secured to housing 41. When the table is in forward position, index 104 points to "1" on plate III, the slip 8 has its first or top line s in printing position; and lever 192 is engaging the left hand notch 190 to impositively hold the table against movement. To position the table for locating the second line s in printing position, the operator moves the table towards the front of the machine until index 104 points to "2" on plate 18l; and lever 192 coacts with the second notch 188 to maintain the table in second line position. To position the bottom or third line a In printing position, the table is moved towards the front of the machine until index 114 points to "3" on plate 195; and lever 182 coacts with edge 188' to hold the table against movement.

When the sales slip is placed on table III, Its leading edge moves beneath a guide plate 1I8 (Figs. 2 and 5) of thin spring steel which is solid below the spaces between adjacent banks of type wheels 43 and cut out below the banks of type wheels. The ink ribbon R is led from one spool 101 (Fig. 1) forwardly, then suitably guided upwardly, then horizontally between guide plate 8I and a similarly cut out guide plate 183 of spring material which keeps the ribbon away from the type wheels 43 so as not to interfere with rotation of the latter wheels. The ribbon is then guided downwardly and rearwardly to 30 the other ribbon spool 191'.

The means for feeding and reversing the ribbon feed need not be explained herein as such means are well-known and may be of any suitable type. Access may be had to the ribbon spools by removing table 8I from its carrier.

Below the type wheels is located a divided or sectional platen 201 carried by spring steel webs 211' (see Figs. 2 and 5) resting at their left or forward ends on screws 201 adjustably carried by a cross bar 202 of a bail 203. The webs 201' are formed with vertically bent ears 200a rotatably mounted on a shaft 204 journaled by frame plates I1 and 11' Ball 203 is rotatably carried by the ends of shaft 204, and the right side of the bail (as viewed in Fig. 2) is formed as a bell crank lever 205 provided with a roller 206 riding on a cam 201 on cam shaft 3I. A spring 208 urges the ball counterclockwise (Fig. 5). During the cycle of cam shaft 30, cam 201 rocks ball 203 clockwise (Pig. 5) to cause platen 200 to press the slip S and ribbon R against type wheels 43 to effect printing of a line s of the data set up on the type wheels.

After the printing operation, a stud 209 extending from the side of cam 201 rides past the inclined rear end 216 of lever 192 to rock the lever counterclockwise (Fig. 5) and release it from table support 182. If the support is in either position "2" or "3" when released by lever 12., then it is moved forwardly to position "1" by spring 188. Thus, after each printing operation, table J18 is automatically moved to locate the slip 8 for receiving an imprint in the first line a.

This assures the first item of a transaction being printed in the first line s of the sales slip, and avoids the possibility that the operator may fail to set the table to this line when inserting a new sales slip.

The means for feeding a card T into punching position and ejecting the card subsequently to the punching operation will now be explained.

Card feeding and efecting means A supply of cards T is maintained in a maga- 75 L __ zine 212 (Figs. 3 and 23), the top of which is part of housing 40, the bottom of which is a plate 213 and the back of which is a plate 214.

The cards project through the open front end of magazine 212 to be conveniently accessible for removal by the operator. After the key setting operations have been completed, the tokens P and G inserted, and sales slip 8 placed on table 180, the operator removes the top card from magazine 212 and slides it between upper and lower guide plates 215 and 216 and into punching position. A three-sided border strip 2 l' is fastened to lower guide plate 216 and shaped to conform to the sides and the left edge including the oblique corner of a card T (see Fig. 1). The border strip 216' combines with plate 211 to form a recess or pocket for snugly receiving the card and locating it in correct relationship to the punch slides II.

When the card is inserted between guides 215 and 211, it moves without hindrance between the chordal, flat, portions of upper and lower feed rollers 217 and 211. Guide plates 215 and 216 are cut out opposite feed rollers 211 and 218 to permit the circular portions of the rollers to move into the passage formed between the guide plates to grip and feed the card forwardly. The shaft of upper roller 211 carries a gear 211 meshed with a gear 220 on the shaft of lower feed roller 218. Gear 229 is driven by an intermittent gear 221 rotated through bevel gearing 222 from cam shaft 31.

Gear 221 has teeth through an arc of 72* for meshing with gear 220 after the punching operatlon and thereby effecting a single revolution of feed rollers 211 and 21i. The rotation of the feed rollers moves their round portions into the card passage between guide plates 215 and 21i to grip the card and feed it part way into a delivery receptacle 223.

The front wall of receptacle 223 is formed by plate 214 of the card supply pocket 212. The bottom of the delivery magazine is a plate 224 carried by the top flanges of standords 225 and 221 (see Figs. 1 and 3) and inclined downwardly at its left end (Fig. 3) to provide, in conjunction with the lower curved end of plate 214, a clear card passage in line with slots II of the punch slides. When feed rollers 211 and 211 feed the card past frame plate II, the card moves up along the inclined front end of bottom plate 224 of the receiving magazine 223 and onto the chordal, fiat, portion of an ejecting roller 221.

The shaft of roller 221 has a pinion 228 for coacting with an intermittent gear 221 which has teeth along an arc of 72* which mesh with pinion 228 after the feed rollers 211 and 218 have completed their revolutions. The gear 23i is driven by bevel gearing 231 (see also Fig. 1) from cam shaft 31 and rotates ejecting roller 221 for one revolution. During this revolution of roller 227, its round portion moves, through a slot in plate 224. above the surface of the plate, and grips the partially ejected card to move the latter along the bottom of the stack of cards in magazine 223 while, at the same time, lifting the stack above the plate 224. At the end of the revolution of roller 221, the card is completely ejected into magazine 223 and rests on top of plate 224.

A weight 231 on top of the stack of cards in magazine 223 provides the necessary friction between roller 221 and the card being ejected by the roller.

Delivery magazine 223 i closed at the top by a door 232 (see Figs. 3 and 23) and a lock is provided to permit only authorized persons to open the door and remove the punched cards.

The upper part of an elongated, vertically disposed abutment plate 233 (see Pigs. 3 and 9) blocks card passage or slot 237 formed in frame plate IS. When the card moves into punching position, Its leading end engages the upper part of abutment 233 and moves the latter to the right (Fig. 3) against resistance of a spring 234 connected to stud 235 of the abutment (see also Fig. 9). The movement of the abutment to the right Is limited by engagement with the lip of a plate 231 secured to frame plate Il. Thus, the card is located properly in punching position by engagement of its leading edge with abutment 233; by engagement of its other edges with border strip 211'; and also, within the field of the slides 10, by engagement with the vertical sides of comb bars 20 and 21 (see Figs. 6 and 8). Near its lower end, abutment plate 233 has a hole for loosely receiving a pin 238 extending from the side of a pivoted arm 231 which is urged clockwise (Pig. 9) by a spring 240. Pin 238 also passes loosely through a hole in a vertically disposed plate 241 (see also Fig. 2) lying flat against the face of plate 233. Both plates 241 and 233 are vertically slotted at their lower ends to straddle a stud 242 between the head of which and frame IS, the lower ends of the plates are confined in a manner to permit a limited rocking of the plates. Another stud 243 extending from frame 18 passes through alined vertical slots of plates 233 to guide the latter for vertical movement. The plates are also vertically slotted intermedlately to straddle shaft 39.

Plate 241 Is normally maintained throughout its length flat against the adjacent face of abutment 231 by a spring 244 surrounding stud 235, and confined between a washer 245 on the stud and the face of plate 241. Projecting from plate 241 is a square lug 241. When plates 233 and 241 are in initial position, lug 246 abuts the radial edge 241 of a cam disk 248 on shaft 39 to prevent rotation of shaft 31 clockwise (as viewed In Pig. 9). As shown in Figs. 3 and 10, gear 136 of shaft I3 is meshed with a gear 250 operated by crank handle 251. Two turns of the handle moves shaft 3I through a single revolution.

Shaft 33 is permitted to move only counterclockwise (Fig. 10), reverse rotation being prevented by engagement of the teeth of gear 136 with a pawl 252 of spring metal.

When there is no card in punching position, spring 234 holds plates 233 and 241 in the position shown in Fig. 3, and lug 241 of plate 241 abuts edge 241 of cam disk 248 to prevent rotation of shaft 30 clockwise, as seen in Fig. 9 or counterclockwise, as seen in Fig. 10. Insertion of a card in punching position moves plate 233 to the rear or right (as viewed in Pig. 3). As plate 233 moves to the right, through spring 244, it causes plate 241 to follow and displace its stud 246 from In front of edge 241 of cam 248. This releases cam shaft 31 for rotation by crank handie 251.

After the punching operation, edge 247 of cam 241 engages the free end of lever 231 and depresses it against resistance of spring 241. When arm 239 moves down, its pin 231 lowers plates 233 and 241. As a result, the upper end of plate 233 moves below card passage 237 of frame Is and out of the path of advance of card T.

Feed rollers 211 and 211 then function to partially eject the card into magazine 223, and the ejection is completed by roller t21. When the plates 233 and 241 are lowered out of the path of the card, they are no longer pressed to the right (Fig. 3) by the card, and therefore spring 234 moves the plates forward again. Stud 246 thereby is located in position to abut edge 241 of cam 248 and stop shaft 3I when the shaft has completed its one revolution. Just before the end of the revolution, the concentric high dwell portion of cam 248 rides off arm 238, and spring 241 again raises the arm which in turn elevates plates 241 and 23i to place plate 233 in the path of the next card.

At the beginning of a cycle of shaft $3, plates 233 and 241 are in forward position, and stud 241 coacts with edge 241 of cam 248 to prevent counterclockwise movement of shaft 31.

This also prevents turning of crank handle 251.

At this time, if the operator attempted to turn 0g the crank, he would merely exert pressure by edge 241 of cam 248 against stud 246 of plate 241. If, while thus exerting pressure on the stud 246, the operator also moved a card Into punching section, the forward edge of the card would 2s engage abutment 233 and move it to the right against resistance of spring 234. The pressure exerted by edge 241 on stud 245 may be suicient to prevent plate 241 from moving to the right along with plate 233. Plate it8, however, is able to move to the right without any interference from plate 241, merely compressing spring 244 when so doing. This yieldable connection, spring 244, between plates 233 and 241 permits plate 233 to be moved to the right by the card although plate 241 is held in Its Initial position by the pressure exerted on its stud 241 by edge 241 of cam 241. If card abutment 233 and plate 241 were one piece, or were rigidly connected for common movement, then the pressure exerted by edge 241 on stud 246 would prevent the card from moving the card abutment to the rear and as a result, the card might be damaged.

By forming the card abutment in two parts, yieldingly connected to each other, injury to the card is prevented without interfering with the function of the abutment in preventing rotation of cam shaft 31 before a card is inserted.

After inserting the card, should the operator s5 still be unable to turn crank 261, he will understand that he is exerting too much pressure on the crank. He will then release the crank, and spring 244 will Immediately snap plate 241 to the right to lie fiat against abutment plate 233, thereby releasing shaft 38 for rotation.

Summary A summary of the operations required to record the sales transaction consisting of the 60 three items indicated on the sales slip shown in Fig. 13, will now be given.

Clerk No. 11 makes three "charge send" sales, the code designation of which is "4" to a customer having an account No. 209195. The first article sold is a piano, having a code number "009". The date and department numbers have been pre-set, and the punch slides lid and b and corresponding type wheels 43d and b are already in position to respectively punch and print the date and department designations.

The customer's number and the kind of goods designations are set up by tokens P and 0. The remaining items are set up by keys II.

The tokens may be Inserted first or else the key set-up made first. Token 0 (see Pig. 15) marked with code No. "009" is placed In pocket I1 and the customer's token P (see Pig. 15) In pocket II.

Keys 1 are then operated one at a time to successvely set up, in order, the first sales item g which includes the amount, 1250.00; the kind of sale; and the clerk's number 11. The' order of operation of the keys must always be for amount, kind of sale, and clerk's number in succession since this order is predetermined by the arrangement of slides 14 t, t, and o and the corresponding printing wheels 43.

The first operation of a key 15 is to set up amount digit "1" of the highest order. The operation of the key causes rotation of a drum II (Pigs. 1, 6, and 7) to set all the nine item wheels i8 initially meshed with the drum to the "1" position. The operation of the key also results in rotation of threaded shaft I8. Rotation of shafitI Is controlled by an escapement mechanism shown in FIg. 11 and results in moving carriage N of item wheels I3 one step to the left (Pigs. 1 and 2), causing the left hand wheel to move off the drum and into mesh with the right hand, units order, slide lip. The reading "1" on the latter item wheel is then visible through sight window 84 (Pg. 23) of casing 48.

The second key operation, to set up amount figure "2", results in the eight wheels 3 still on drum II being commonly set to reading "2". The escape operation resulting from the second key operation moves the first left hand wheel t3 still reading "1" from units order slide 1ic and Into mesh with the next, tens order, slide Ile, and at the same time moves the second S2 wheel 83 from the left off drum II and Into mesh with units order slide 1c. The reading "2" of the latter wheel Is then visible through sight window 14 together with the reading "1" of the first item wheel. The third key operation sets up amount digit 5 on the seven wheels U still on drum I and moves the nine wheels another step to the left, bringing the first wheel from the left (Pig. 2) into mesh with slide Ift, the second wheel into mesh with tens order slide Iec, and the third wheel into mesh with units order slide lSc. In similar manner, the remaining digits 0.00 of the amount, the digit 4 representing "charge send", and the clerk's number 11 are successively set up on wheels 1 by successive operations of keys 15.

At the end of the nine key operations, the nine wheels 3 are ll to the left of and demeshed from drum II. The first wheel from the left Is 5 in mesh with "thousands" dollar order slide 1la, (the first from the left, Pig. 2), the second wheel is meshed with "hundreds" dollar order slide Ika, the third wheel is meshed with "tens" dollar order slide Ila, the fourth with dollars order 6 slide Ika, the fifth and sixth with the dimes and cents orders of slides Ia, the seventh with slide 18t, and the eighth and ninth with tens and units order slides I c. The readings on the wheels are also visible through sight window 34 formed 5 in housing 40.

Sales slip S may be placed on table IS now or before the set up operations are begun.

Table Il1 Is normally In the position indicated in Fig. 5 to locate the top line s of the slip at 0 printing position.

After completion of the set Up operations, after the tokens P and 0 are inserted, and after slip S is in printing position, the operator inserts a card T between guides 1II and 111 Into punching po- 76 sition. The Insertion of the card moves plates 211 and 241 to the rear, withdrawing stud 241 from the path of movement of cam 241 on shaft I3 and thereby releasing the shaft. The clerk now turns crank 251 through two revolutions to move shaft 39 through its single revolution cycle.

During this cycle of shaft 39, the slides Ip and g and corresponding type wheels 43p and g are set under control of tokens P and G; slides I0a, t, and c and corresponding type wheels 43 are set under control of wheels 83, printing of slip 8 is effected, card T is punched, and the card ejected.

The timing of the various operations will now be described.

The setting of slides lSp, g, a, t, and c is controlled by cam 6I (Fig. 8). Referring to the fourth line of the timing diagram, Pig. 22, at 10" of the cycle, roller II' begins to move along the descending portion of slide balW cam 6$, permitting springs 62 to move arms 8I to the left, the arms in turn acting on restoring bar 63 and link 1I to cause roller 6I to follow cam I6. During the next 85' of the cycle, cam 61 permits arms (I to rock counterclockwise (Figs. 6 and 8) to advance slides lip, g, a, t, and c.

Slides lip and o advance to sense designation slots 48 of tokens P and G and are arrested by the tokens in differential positions corresponding 80 to the designations represented by the slot. As these slides move to their differential positions, through gears 46 and 42, they correspondingly set type wheels 4Ip and g.

As slides I(a, t, and c advance, between 10' and 956 of the cycle, they rotate wheels 83 meshed therewith in a clockwise direction (Fig. 6) until the pawls 148 of these wheels engage shoulder 141 of shaft 8I. The wheels 83 are thus zeroized, and slides I a, t, and c are arrested in differential positions determined by the values subtracted from the wheels in order to zeroize them and corresponding to the :ey set ups. As slides I a, t, and c move to their differential positions, through gears 15I, they correspondingly set type wheels 43a, t, and c.

Thus, at 95* of the cycle, all the slides and type wheels have been set In positions to punch card T with the data of the first item of the sales transaction, and to print these data in the 5o first line a of the sales slip 8.

Between 100* and 178* of the cycle, cam 38 rocks lever 32 clockwise (Fig. 5). Referring to the fifth line of Fig. 22, between 100* and 120* of this movement of lever 32, pins 321 (see also Fig. 8) cammingly coact with the upper, inclined portion of slot 322 in ball 14, to depress slide liner or locking bar I3. At the end of this movement of bar 36, it has locked and alined slides 10 and type wheels 43 In their exact, differential positions. Pins 321 then start moving downwardly along the now concentrically disposed edges 323 of bail 34.

At 130* of the cycle, pins 321 reach the bottom of slots 31' in links 1 and start depressing the punch or pressure plate 26 (see the seventh line, Pig. 22). Between 150' and 165', the punch pins 12 penetrate card T, then continue to move downwardly for the remainder of the clockwise movement of lever 12, which ends at 178". Cam 38' (Fig. 5) now starts rocking lever 32 counterclockwise (Fig. 5), and the lever moves In mid direction between about 180* and 220* of the cycle. Between 180* and 195', pins 328 move from the lower ends to the upper ends of slots 31' in links 31, and then start raising the punch operating assembly. At 210*, stripper bars 23 of the operating assembly have raised the punches 12 clear of card T. The pins 321 then begin to coact with the upper, inclined portions of slots 322 of ball 34 to raise slide liner 36. As indicated by the fifth line of Fig. 22, the slide liner 36 is , completely unlocked from the slides at 2200, at which time the punch operating assembly has completed its upward, restoring movement.

At 180°, before bar 36 unlocks slides 10, cam I14 (Pig. 6) acts on lever 112 to cause check pawls 166 (see the sixth line, Fig. 22) to engage ratchet teeth 165 of slides 10a, t, and c. .When bar 36 releases the slides at 220°, check pawls III prevent these slides from advancing under the influence of springs 62. .The check pawls are released from the slides at 340° of the cycle.

At 130* of the cycle, at the same time as the punch operating assembly begins to move down, cam 217 (Fig. 5) acts on arm 205 of bail 203 to rock platen 200 upwardly, and between 170* and 205' (see the eighth line, Fig. 22), the platen coacts with ribbon R and type wheels 43 to effect printing of a line of data s on slip S. Thus, the printing operation is completed before slide alining and locking bar 36 starts releasing the slides at 210°.

The card is now ready to be ejected to storage magazine 223. At 175", which is after punches 12 have penetrated the card, edge 247 of cam 248 (see Fig. 9) engages the nose of lever 239 to rock the latter counterclockwise. As lever 239 moves in this direction, its pin 238 lowers plates 241 and 231 (see the twelfth line, Fig. 22). At 185°, the abutment plate 233 has been lowered completely out of the path of advance of the card, leaving the card free to be ejected by front feed rollers 217 and 218 and by rear feed roller 227.

At 218", the teeth of gear 221 start meshing with pinion 220 to rotate feed rollers 211 and 218 for the next 72" of the cycle (see the tenth line, Fig. 22). Feed rollers 217 and 218 partially eject the card into magazine 223 and move the card onto rear feed roller 227. Rotation of feed roller 227 by gear 221 begins at 287' (see line 11 of the timing diagram, Fig. 22), and is completed at 357°, resulting in the complete ejection of the card into delivery magazine 223.

The remaining lines of the timing diagram will now be explained: Between 5* and 15" of the cycle, cam block 131 (Fig. 10) causes arm 142 to place its nose end in the path of special zero stop finger 78'-0 of shaft 71 (see also Figs. 2, 4, and 16), and to simultaneously release detent 104' from teeth 103 of disk 102 of shaft 79. Through the next thirty degrees of the cycle, spring 98 (see Fig. 7) moves shaft 78, drum II, and those wheels 13 remaining on the drum after the key set-up to approximately zero position. The cam block 137 then rides off arm 139', permitting spring 105 to restore detent arm 164 and special zero stop arm 142 to their initial positions, and detent arm 104 engages a tooth 163 of disk 102 to stop shaft 79, drum 81, and wheels 83 thereon in their zero positions. Between 55° and 130° of the cycle, cam 145 (see Fig. 7) engages roller 146 of gear sector 96 to rock the sector counterclockwise and to retension drum actuating spring 98.

At 120* of the cycle, cam 160 (see Fig. 4) releases link 112 for movement to the left by spring 164 to thereby rock shaft 85 clockwise, so as to withdraw its shoulder 149 from zero pawls 148 of item wheels 83. This action is completed at 135' and is for the purpose of relieving the pressure between shoulder 14 and pawls 148 during return of wheels 83 to drum 11.

Between 140* and 230° of the cycle, cam II8 (see Fig. 11) engages roller III of sector 12, and rocks the sector counterclockwise to retension spring 122, and to cause rotation of screw shaft 81 clockwise. Rotation of shaft 89 moves item wheel carriage 88 to the right (Pig. 1) to return the item wheels 83 to their initial stations on drum II.

At 220°, the punching operation had been completed and bar 38 released from slides I1. At 225°, the printing operation had been completed and platen 200 restored. Thus, slides 10 may freely be restored after 225°. At 240*, cam 8I starts moving link 6I to the right and bar 63 moves clockwise (PFgs. 6 and 8) for the next 1000, picking up all the arms I6 and restoring them and their connected slides II to initial positions.

90 At 3458 of the cycle, cam g6 (Fig. 8) rocks lever 68 clockwise. Through link 10 and pin I1, this withdraws latches 5I from slots 41 of the tokens and springs 54 act on members I3 to eject tokens P and G from their respective pockets II and 62.

32 At 350° of the cycle, stud 201 of cam 281 (see Fig. 5) rides past inclined tip I10 of lever 192 and releases the latter from table support 182. Spring III (Fig. 1) then restores table III which carries the sales slip, to the first line printing position.

This completes the series of operations required to print a single line s of data on sales slip 8 and to punch these data in a card T. To record the second sales item of the transaction on the same slip 8, the latter is left on table 180 and the table set in second line printing position. The keys 71 are then set up for the new amount, the same clerk number, and kind of sale. The same customer token P and a different token G, identifying the second article purchased, are inserted in pockets II and 2., and then a second card T placed In punching operation. Shaft 13 is then moved by the operator through another cycle, resultingin printing the second line # and punching the second card T.

Similarly, the data shown in the third line on slip 8 are set up and printed and a third card punched.
