Description:

This invention relates to an improved amusement device and particularly to such a device of the pin board type, wherein balls may be rolled over a board having groups of pins surrounding openings, the latter having different scoring values. Balls passing through certain of the openings may also be effective in operating suitable playing disk return means adapted to give a series of playing disks to the person using the machine, these disks permitting the person again to play the game. Thus, a game of this type may be played by inserting a disk in a suitable receiving mechanism and by actuating handles or manually operable controls to cause the movement of the balls into proper position and the successive projection thereof over the pin board itself. If the balls pass into' certain openings, a return mechanism is actuated to permit a plurality of disks to be supplied by the machine so that the player may use them in repeated operations of the machine. Often players of games of this type become very skilled and used to the peculiarities of individual machines so that they may manipulate the machines in an unfair manner to obtain more frequent return of disks than are warranted. Under such conditions, the machine may be subjected to wear and rough handling of undue severity. Thus machines of this type may be tilted to permit the rolling of the balls into openings effective to return playing disks, while in numerous cases shaking or vibrating of the machine may have a similar effect, or a properly timed repetitive manipulation of the disk receiving slider of the machine may be effective in causing unmerited premiums.

The present invention is effective in affording an improved, accurately operating machine of this general type, particularly adapted to afford the same chances of obtaining a return of disks under all normal operating conditions, and being substantially immune to improper operation.

Thus, a machine of this type is arranged to avoid the obtaining of undeserved disks when it is tilted or either the whole machine or the disk receiving portion thereof is vibrated or shaken.

Furthermore, the present invention affords a novel arrangement of trip elements operable by balls receivable in a certain series of openings in the pin board; accordingly, a machine of this type rather than returning one or two disks in response to the reception of balls by various openings, may give a larger number of disks when balls are received in each opening of a combination or set of openings, such as three openings. Thus interest in the game may be stimulated. In a typical embodiment of the invention, four sets of three openings each may be afforded to return disks, each set of three openings being arranged to give a different number of playing disks, if desired. To permit these resuits, the present invention affords an arrangement of associated instrumentalities effective to permit the operation of the game device in the conventional manner, these instrumentalities including various associated electrical switches and circuits as well as cooperating mechanisms. A tilting control may be afforded to interrupt flow of electrical current through the inain operating circuits when the machine is tilted, as well as to cause the energization of a warning light, thus to prevent operation of the return mechanism due to tilting of the machine, in an attempt to evade the conditions imposed by regular operation of the machine.

Furthermore, switch means may be afforded to preclude possibility of manipulation of the disk receiving portion or slider of the mechanism to cause unmerited operation of the return mechanism or a repeated operation of the same when but a single operation is proper. Associated with the electrical means and included therein are a plurality of trip operated switches associated with each of the sets of openings above referred to.

Thus, when balls are received in each opening of a given set, corresponding switches may be closed to permit the flow of current to the return mechanism. This mechanism itself may be provided with electrical control means effective to an unwarranted repeated operation of the disk returning mechanism despite any jiggling or shaking of the machine.

To facilitate an understanding of this invention, I will first generally describe' a well-known type of game device to which the principles of s5 this Invention are applied. This machine or game device comprises a generally rectangular casing 1, which may be mounted on suitable legs 2 and provided with an inclined cover 4 in the form of a suitable glass panel, so that the movement of the balls within the casing may be readily witnessed. A mirror or advertising panel 5 may be disposed at the rear of the machine. Disposed in the upper part of the rectangular casing I Is the pin board proper, designated by numeral 0. This board is provided with a marginal frame adapted to act as a guide for the balls and is slightly inclined upwardly toward the rear so that the balls ejected toward the rear wall or abutment surface II normally roll down toward 0 the front end of the machine where they may be received in slots 13. The board I! is provided with a series of openings 14 of a size to receive a suitable ball. Disposed on the board in various spaced positions as well as in groups or rows about or in the vicinity of the openings are pins 16 against which a ball may strike or roll, thus being diverted from its original path and adding to the interest of the game.

At one side of the board 18 a groove or alley 17 is provided along which a ball may be impelled to the playing surface of the board. A spring 19 mounted on an upright pin or stud 20 at the outlet end of alley 17 is arranged to prevent return movement of a ball from the body portion of the board 10 to the alley. Beneath the pin board 10 is a lower board 10 (Fig. 5) forming the bottom of a ball receiving chamber. Thus balls passing downwardly through openings 14 or slots 13 ultimately pass into this chamber, as will be more fully explained, and may roll downwardly into a receiving compartment at the front right-hand corner of the machine. A swinging arm 31 provides an end plate 32 movable in this chamber to engage a single ball and elevate to ra the region of a transverse, substantially eWitcircular passage or trough 33 through which the ball passes into the alley 17, this general arrangement of the ball return mechanism being well known and conventional in the art. A handle 29 is provided to actuate the elevator parts 31 and 32 through linkage 34.

A plunger 35 extends into the front end of alley 17 and is normally held in the position shown in Fig. 2 by a coiled spring (not shown) disposed within casing 36. The plunger Is provided with a handle 37 on the outside of the machine, this handle being operable to cause retraction of the plunger so that it may be returned to or snapped back to its normal position by action of the spring within the housing 36, thus driving a ball along the alley II past spring 19 in the direction of the curved border surface I of the pin board, whence the ball may roll forwardly over board 10, normally passing into engagement with certain pins 16 and perhaps falling into one of the openings 14 or perhaps continuing to the lower front end of the board and being received by one of the slots 13.

A sliding panel 40 may be mounted beneath the pin board proper 10; suitable supporting brackets 41 engage the edges of the panel 40 to hold it in this position. A tension spring 42 (Fig. 5) is normally effective in drawing the panel 40 toward the front of the machine where it may engage a suitable stop. In its normal position the panel 40 underlies slots 13 and certain openings 14 so that the balls passing into the slots or openings are held in view of the player until a subsequent operation is performed. Special means which will be described and which are assoclated with the panel 40 are effective in holding the balls positioned in other openings so that the total number of balls passing in the openings after a given period of play or plays with a set of balls of determined number may be readily ascertained. Ordinarily the scores which are counted for rolling the balls into the individual openings are indicated on the board itself so that the player can readily calculate his score.

Colored circles F may be painted on the board 10 to identify the sets of openings which are particularly significant in operating the disk returning mechanism; thus each set of openings may be identified by different colored circles.

At the front of the machine is a light T disposed beneath a suitable glass panel. Upon the panel a suitable word such as "Tilted" may be printed so that the glass behind this word is illuminated when the light T is energized, the tilting control device being effective to stop normal operation of the playing disk returning mechanism and causing energization of this light If the machine is tilted to an appreciable angle, as will be more fully explained.

Now referring in detail to the disk-receiving mechanism, it is to be understood that a fixed bracket 50 receives a slider 51, this plate, as shown, having a circular opening 52 (Fig. 3) over a smaller opening on bracket 50 to provide a generally annular rabbet upon which the margin of the disk may rest. As shown, a projection 54 is provided on the bracket to prevent the operation of the machine with an ordinary circular slug having, for example, the shape of a conventional coin, but only permitting operation of the machine with a special playing disk having a cut or slot in its margin to fit the projection 54.

A tension spring 56 is connected to a. transverse bar 51 at the inner end of the slider 51. I7 The bar 57 engages a depending lug 59 on sliding panel 40 so that the panel 40 may be slid toward the back of the machine when a disk is inserted in the recess 52 and passes under the conventional latching mechanism (not shown), thus permitting the slider to push the lug 59. A swinging switch element 61 affords one contact of a switch A adjoining the slider 51. The member 61 is normally held in position by the bar T7, but when the slider 51 is pushed inwardly the element 61 may swing so as to separate its contact from the fixed contact 68 of the switch A, a spring 63 tending to cause the switch to open.

After the bar 57 is returned to its normal position, it engages an insulating block 60 at the end of clement 61, thus automatically to cause closing of the switch. Accordingly, the flow of current through switch A is interrupted only when the slider 51 is pushed inwardly to cause movement of the panel 40.

At the rear of the machine (Figs. 5 and 14) are a plurality of fixed magnets D arranged in parallel circuits, as will be described; each of these magnets is associated with a swinging armature 65 pivotally mounted on a bracket 69 depending from the board 10. A spring 71 normally holds each armature 65 in the retracted position shown in Fig. 5 wherein the armature serves as asa lock to hold a swinging support 10 in the illustrated tilted position.

The plate 70 supports a mercury switch C which, when in the position illustrated in Fig. 5, is effective in closing contacts between leads 74 and 75. When the magnet D is energized, the locking armature 65 is moved out of the illustrated position so that the adjoining end of swinging support 70 moves downwardly to break the circuit between leads 74 and 75. When the parts are in this position and panel 40 is moved toward the rear of the machine, a depending lug or ear 80, carried by this panel, engages the downwardly inclined portion 70a of member 73 to swing the latter and the switch C to its normal position, whereupon the spring 71 may be effective in moving the locking armature 65 under the opposite end of member 70 to support the latter in its normal tilted position.

Beneath certain of the openings 14 are trigger elements 90 which are in effect extensions of 0 swingingg brackets 91 supporting mercury containing tubes or switches 93, these switches being inserted in series with consecutive sections of leads 75. Preferably there may be several sets of switches 93 arranged in series. Thus, there may be four sets of three openings provided with trigger elements 90, the switches of each set being in series so that the closing of the three switches due to the reception of balls on the corresponding three triggers 90 is effective.in closing a circuit in order to operate he playing disk returning mechanism in the manner which will be more fully described.

Fig. 5 illustrates the normal position of a trip or trigger 90 i lan relation to the opening 14. Disposed beneath the opening is a depending sheet metal member 92 of substantially U-shaped cross section. The trip 90 and its continuation, which carries an upstanding stop 94 for switch element 93, extends through the opening between the legs of this hood 92.

Fig. 15 illustrates the position of parts 90 and 93 when a ball has been received in the corresponding opening 14. As shown in full lines in this figure, the member 90 is tripped so that stop 94 engages panel 40 as a stop, the circuit between lead sections 75 being closed In this position of the parts and the ball being supported in the opening 14. It is thus evident that the trip elements 90 are effective in holding the balls in the corresponding openings 14, while portions of the panel 40 are effective in supporting the balls in the other openings. Thus after a set of balls has been projected onto the board, the balls which have been received in the scoring openings 14 may be readily observed, and the player can calculate his score. After this has been done, and when the slider 51 is again actuated to move the panel back, each element $0 is moved rearwardly with the panel into the position shown in dot and dash lines in Fig. 15, thus moving away from the hood 92 so that sufficient room is afforded to permit the ball to pass through the opening thus provided onto the board 30. Thus when the panel 40 is slid toward the rear of the machine it moves the trips 90 out from the positions wherein they retain balls in corresponding open- o2 ings 14, while it moves to cause openings formed in the panel 40 itself to register with the remaining openings 14 as well as with the slots 13.

Thus return of the balls to the elevating and projecting instrumentalities is permitted. Mounted on board 10 between magnets D there is a conditioning switch 13 carried on a support 170 similar to the support 70 of switches C. A lug or cam element 180 similar to the elements 80 is effective in temporarily tilting this switch and 31 closing the circuit between its leads 200 and 205 when the panel 40 reaches its rearmost position.

Normally the lug 180 is spaced from switch 73 so that the latter is opened. This switch is arranged to condition the tilting control after the 3o device has been tilted in order to permit resumption of normal operation.

The tilting control illustrated in Figs. 10 and 11 has a masterwitch 100 i s 0 i eries with the various sets of switches 93. This control is provided with a sw'nging support 99 carrying the master switch 100 having leads 101, 102 and 103 extending into the same and arranged so that a circuit may be closed between either leads 101 and 102 or between leads 101 and 103. Adjoining the master switch 100 is a standard 105 fixedly connected to a base plate 107 which is secured by fastenings 109 to a suitable horizontal board or lower closure member 108 that may. for example, be disposed beneath the board 30 (Fig. 1). Accordingly, tilting of the machine, including the board 108, out 50 of horizontal position causes inclination of the upright 105. Fixed on the upright are e a series of brackets 110 which support a plurality of mercury switch elements I I, these elements each having a slight inclination from the vertical in each one of four different directions and containing a quantity of mercury such that the tipping of the plate 107 and consequent inclination of the upright 105 to a slight angle may be effective in bringing one of the elements I i I to a circuit closing position. The closing of this switch is effective in energizing the magnet M which causes tilting of the master switch 100 against the action of spring 104 to open the circuit between leads 101 and 102 and close the circuit between leads 101 and 103. The dot and dash line showing of Fig. 11 illustrates this tilted position of the master switch wherein its support may be locked by the swinging latch 114 which is actuated by the leaf spring 115.

For an interval after such a tilting operation the master switch may remain locked in the position shown in dot and dash lines. An electromagnet R is disposed adjoining the upper end of .T latch 14 and is capable of being energized, as will be described, to move the latch out of engagement with the support 99 permitting the spring 104 to move the support 99 and master switch to the position shown in full lines.

Upon the base 108 I also provide a mercury switch 116 which is fixedly mounted in relation to the base and is connected in series with the switch 100 through lead 101. The switch 116 is. ,0 arranged to prevent tilting of the entire machine to cause inclination of the switch 100 when it occupies its dotted line position and consequent closing of the circuit between leads 101 and 102, which might result in operation of the disk returning mechanism, as will be more fully described in connection with the operation Of the machine.

The disk-receiving mechanism is arranged to release a disk from recess 52 of slider 50 when the latter moves inwardly to move the panel 40. and permit the balls to drop through openings 14 and slots 13. The released disk is received by a circular hopper 120 (Figs. 6 and 7). Rotatable in this hopper is a star wheel 121 having semicircular recesses cooperating with the inner wall of hopper 120 in defining compartments in which a series of the playing disks or tokens may be Sreceived.

Secured to the wheel 121 is a ratchet pinion 122. Above pivot 122, an arm 119 is independently rotatable and carries a pawl 123 effective to turn wheel 122 and star wheel 121 in an anticlockwise direction, as viewed in Fig. 6. The end of arm 119 carries an element 124 having a V-shaped recess, in which the pin 118 on arm 57 of the disk-receiving mechanism may engage (Fig. 3), thus to cause an oscillatory movement of arm 119 and a movement of pawl 123 sufficient to move the pinion wheel 122 a single step in response to actuation of slider 51.

The bottom of hopper 120 is provided with outlet passages 125 disposed over disk grouping and dispensing wheels 130 which are pivotally mounted on horizontal shafts and have radial recesses 4 131 (Fig. 8) to receive a plurality of the playing disks. The recesses 131 upon one side of each of the wheels 130 may normally be filled with disks, while on the opposite side of the wheels these recesses may be open. On the first-named side of each wheel a suitable substantially semi-circular hoop element 135 may be provided to prevent outward movement of the disks from the recesses as the latter move toward an inverted position, the elements 135 terminating adjoining the lowermost portion of the periphery of each wheel so that when a recess arrives at the bottom of the wheel it is free to emit the disks contained therein into a discharge passage 136. Thence the disks fall into a sliding drawer 138 accessible from the exterior of the machine (Fig. 1).

Suitable mechanism is provided for operating the various dispensing wheels in response to the actuation of a set of triggers 90. For this purpose a plurality of solenoids S are provided, the solenoids corresponding in number to the dispensing wheels 130. Each solenoid is provided with a plunger 140 connected by a link to the outer member 141 of a ball clutch unit such as shown in Fig. 9, so that movement of a plunger 140 in one direction, i. e., to the right in Fig. 7, may be effective in causing the rotation of the clutch element 141 and the adjoining element 142 which is fixed to one of the dispensing.wheels 130. Accordingly the energization of the solenoid may be 6 effective in causing rotation of the corresponding dispensing wheel 130 through a fraction of a revolution to permit release of disks from a recess 133.

Normally a spring 152 retains the latch 150 in engagement with a notch on a control wheel 151 which is associated with each dispensing wheel 130 to hold the latter in a fixed position.

A magnet N may be energized to move the latch 150 out of engagement with the wheel 151, thus to permit movement of wheels 151 and 130 by the corresponding solenoid S. In order to prevent possible movement of the dispensing wheel beyond the proper fraction of a revolution which will permit the dispensing of disks from one recess 131, a swinging stop pawl 154 is provided with a cam lug 155 engageable with the pivotal connection 156 of the plunger link and the ball clutch mechanism so that movement of the plunger to the left may permit the pawl 154 to drop into engagement with the periphery of wheel 151 to act as a stop in engaging an upstanding abutment surface on the wheel. Thus overrunning of the wheel 130 is positively prevented.

At the end of its path the plunger 140 may engage a movable contact 160 of a switch B, which will be more fully described; Next referring to the wiring diagram, current may be received from any source of supply, as, for example, a suitable battery, through a lead 200 which. is associated with a return lead 201.

One side of lead 201 may be connected by a branch 201a to a light T. The opposite side of this light is connected to the lead 103 which terminates in a contact at one end of the master switch 100 of the tilting control 'mechanism.

From the switch tube 100, lead 101 extends to switch tube I11; from the latter the lead 101b extends to a connection with lead 200 and to a lead 10 a that is connected to one side of magnet M. A lead 106 extends from the latter to each of the switch tubes III. The opposite contacts of the latter are connected in parallel by a lead 204 which extends to the opposite side of the magnet M, which in turn is connected to the branch 201b of lead 201. Branch 201b is connected to the magnet R associated with latch 114, and the opposite side of magnet R is connected by lead 205 to conditioning switch 73 (Fig. 14) at the rear of panel 40, the latter being in turn connected to lead 200. The lead 201 is connected by a branch 201 to the fixed element 68 of switch A, the element 61 being bonnected to a lead 20.7.

The lead 102 extends from the master switch 100 of the tilting control and has branches 102a connected to leads 75 joining the trigger switches 93 of each series. Branches 75a of lead 102 are connected to the magnets D associated with the respective main switches C and from each magnet D a lead 209 extends to the fixed contact of switch B, the movable contact 160 of the latter being connected by a lead 210 to the solenoid S, the opposite side of the solenoid being connected by lead 212 to the main switch C.

The lead 210 is extended to join the lead 207, and leads 214 and 215 connect a magnet N in parallel with the solenoid S. The general operation of a machine of this character will now be described with particular reference to the wiring diagram and with general reference to the other portions of the mechanism, the operation of individual instrumentalities and subassemblies having been previously discussed in respective instances.

Assuming that a suitable playing disk is disposed on the recess portion 52 of the slider mechanism, the slider 51 is pressed inwardly to op- 1t erate the bar 57, thus momentarily opening switch A. Under such a condition of the parts current can not flow through the solenoid S and leads 210 and 212. Accordingly, jiggling or vibratory movement of the slider 51 and panel 40 and closing of switches 93 does not affect a solenoid S.

Inward movement of the slider 51 is normally effective through bar 57 and lug 59 in pushing the panel 40 toward the rear of the machine, thus permitting the balls to pass downwardly from the slots 13 in the pin board as well as from the openings 14, which are provided with triggers 90 and the remaining openings. At the same time, should a switch C be open, a member 80 may enis gage the part 70a of the member 70 to return the latter to its normal tilted position shown in Fig. 5, the latch 65 snapping into a position to support the member 70 and switch 73 in this illustrated position. Thus, if the switch C has previously been opened, it will be closed by this operation.

The switch 73 is also momentarily closed by movement of panel 40.

The closing of switches C and 73 conditions the circuits extending between the corresponding series of trigger switches 93 and the corresponding solenoid S. Obviously when the slider is fully actuated in this manner the playing disk is received within the bowl 120 and then the star wheel is rotated a fraction of a revolution. Thus, disks n, are distributed in the various recesses provided by the periphery of the star wheel and the disks are received by the radial recesses in wheel 130.

The slider 51 may then be released by the operator to close switch A, the spring 56 returning this S. slider to its original position; the balls under these conditions have rolled to the chamber adjoining elevator 32, having rolled from the board into this chamber. Under these conditions each switch C is closed, while the trigger switches 40 93 and the solenoid-operated switches B may be open. The handle 37 may then be operated to cause the movement of one of the balls through the trough 33 into the alley 17, whereupon the operator is ready to start playing.

45 The handle 37 is pulled toward the operator and released, the spring associated with this handle being effective in causing the plunger to strike the ball and cause its movement through the alley 17 past spring 19 onto the pin board 10. The 50 ball normally may strike the curved abutment surface II at the rear of the pin board and then roll downwardly, normally striking certain of the pins 16 and either falling in one of openings 14 or passing downwardly to be received by one n. of the slots 13. In this position of the parts the ball may be supported by the panel 40 and/or triggers 90 so that if a competitive game is being played by two or more players, the positions of the balls may be observed to permit keeping of o0 score. Successive balls may be brought into playing position and moved by the plunger 37 in the same general manner as has been described. If the player fails to cause balls to move to each of the holes 14 of one set to engage the correspondC. ing triggers 90, the balls will remain in the described position, resting on the triggers 90 and/or panel 40 in openings 14 or slots 13 until another 'disk is inserted on the slider 51 and the same again actuated, whereupon the panel 40 will be 70 moved to permit the balls to drop downwardly onto the inclined bottom board 30.

While the balls are supported in openings 14 or slots 13, if the player or an accomplice should attempt to obtain the return of disks by tilting of 7. the machine to cause the balls to roll into the openings, a slight tilting is sufficient to cause the closing of the circuit between the leads extending to one of the tubes I 1, this being effective in permitting the flow of current from lead 200 through one side of the magnet M, one of the tubes III, and lead 204 to the other side of magnet M and thence through lead 201.

Accordingly magnet M is energized to cause movement of the master switch 100 out of normal position and the closing of the circuit between leads 101 and 103. Under these conditions current may flow from lead 200 and its branch 101b, leads 101, switch 100, lead 103, light T and leads 201& and 201. Thus the light T is energized to indicate that the device is being tilted. This light may be disposed at the front of the machine, as shown in Fig. 2. If the machine has been tilted in this manner it can not be reconditioned for disk dispensation until another disk has been inserted, whereupon the panel 40 is moved, closing switch 73; and magnet R may be energized to move the latch 114, thus permitting the return of master switch 100 to its normal position.

After the tube 100 has been moved to its dotted line position, as shown in Fig. 11, and locked in that position by the latch 140, a player might maneuver the machine by tilting to cause the balls to roll into openings corresponding to one set of trip members 93 and then tip the entire machine so that the switch tube 100, although in its dotted line position, as shown in Fig. 11, would be inclined sufficiently to close the circuit between leads 101 and 102 thus permitting operation of the disk returning mechanism in the 3s. normal manner which will be described. However, the switch 116 is so arranged that when the entire machine is tilted in this manner, the circuit between leads 10 and 10 1b is automatically broken thus preventing flow of current to the disk returning mechanism.

When a player in normal play is successful in causing balls to engage each one of the trigger elements 90 of one of the sets of these elements, each of the corresponding switches 93 is moved to its closed position. Since the switches A and C are already in closed position, current may pass from lead 200 through lead 101, switch 100, lead 102, lead sections 102a and 75 and switches 93 of the circuit corresponding to the depressed 5C triggers 90. From the last switch 93 of this series the current may pass to the conditioning switch C and thence to solenoid S and to magnet N. The latter releases the locking wheel 151 and the corresponding dispensing wheel 130 while the solenoid S moves the plunger 140 toward the left, as viewed for example in ig. 4, thus turning wheel 130 through the ball clutch mechanism 141, 142. This results in releasing a set of playing disks from one of the recesses in wheel 130 Co so that they pass downwardly through chute or outlet 136 into drawer 138 from which they may be taken by the player. Thus the player may repeat play several times, employing the playing disks thus received. As the plunger 140 approaches the end of its path, it closes switch B, thus causing current to flow through magnet D which is effective in causing movement of the main switch C out of its normal position so that the circuit through the solenoid is automatically interrupted and possibility of repeated actuation of the wheel 130 and repeated dispensation of premiums is avoided. As has been previously described, when the machine is again operated the movement of Ye the panel 40 is effected to ensure the return of main switch C to its normal operating position.

Under conditions of competitive play two or more players having several playing disks may play this game in turn, each projecting the balls over the pin board 16 and computing the scoring values of the openings into which they may roll balls. When a player receives additional disks due to the depression of the triggers .of one set by the balls which he has rolled onto board 10, the additional playing disks permit him to operate the machine a number of additional times and to receive an increased score. It is thus evident that the arrangement of the trigger elements 90 in sets adds to the uncertainty of the game when played by a single player starting with a set of playing disks.

Fig. 13 illustrates an optional switch arrangement which may be substituted for the switches III. In this embodiment of the invention a single tilting switch may be mounted on any suitable support and may comprise a cylindrical holder 300 in which there is a pool of mercury 30 1 beneath a horizontally disposed wire loop 302, 26 the loop being connected to a lead 306 at the top of the receptacle and an opposite lead 307 having a contact immersed in the mercury 301.

With this embodiment of the invention, slight tilting of the receptacle 300 causes contact be80 tween the mercury body 301 and a portion of the hoop 302, thus closing the circuit between leads 306 and 307 which may be connected to the magnet M to operate the master switch 100 in the manner already described.

85 Figs. 16 to 21 inclusive illustrate an optional disk returning mechanism wherein the movement of the dispensing wheel may be effected through a series of manually operated plungers I6la, 161b, 181c or 161d. Within the casing a substantially vertical duct 162 is arranged to receive playing disks from the slider 61. These playing disks therefore become stacked in the lower part of the duct 162 which is supported on a bracket 163 secured upon a supporting frame 164. An opening is provided at the lower end of duct 162 so that disks may pass into circular recessea 165 in a dispensing wheel 166 having a vertical axis of rotation. The support 164 Is arranged below the major portion of the wheel 166, thus providing bottoms for recesses 185, but adjoining the duct 162 a depending passage or outlet 169 (Pig. 16) is afforded to supply playing disks to a chute 112 which is provided with a spring-held closure 171 which may be actuated to release the disks into the hand of the player.

Each of the plungers 161*, 161b, !61f and 161d is connected to a horizontally disposed push rod 174.

Thus in the illustrated embodiment of the invention there are four of these push rods located one above the other. The inner end of each of these rods is provided with a laterally projecting arm 175 connected to a tension spring 116. Thus the spring normally tends to move the corresponding plunger and push rod to the position illustrated in Figs. 16 and 17 wherein the upturned end of the push rod provides a stop member engaging the front wall of the cabinet as an abutment.

Upon the side of each of the rods 174 are a plurality of teeth 17l providing a rack engaging the teeth of a fragmentary pinion 181, a portion of the periphery of which is extended to afford an outstanding plate 182. Secured upon the lower face of the plate 182 is a pawl 183 (Figs. 19 and 20) pressed by a spring 184 into engagement with ratchet teeth of a ratchet wheel 185, the latter being connected to a spindle 188 which is coaxial with and secured to the dispensing wheel 166.

Accordingly when a plunger, as, for example, the plunger 161a, is pushed inwardly, the corresponding push rod 114 is effective in rotating the corresponding pinion 181, thus acting through the pawl 183 to rotate spindle 186 and dispensing wheel 166 in an anti-clockwise direction, as viewed in Fig.

16. Thus one of the openings 165 may be moved over the outlet 169 to emit playing disks into chute 172.

As shown in Figs. 16 and 17, the plungers may be provided in different lengths corresponding to segmental portions of the wheels 186 occupied by a different number of recesses 168. Thus the shortest plunger 161a may be effective in turning the wheel 163 so that the playing disks from one recess are dropped into the chute 172, while the plungers 161b, 161c and 1Ad may be actuated to supply playing disks from two, three and four recesses, respectively.

Preferably each of the plungers normally is locked in its outermost position by a spring-held latch element 190 engaging ratchet teeth 109 upon the side of the push rod 174. Accordingly the plunger can not be actuated to cause operation of the dispensing mechanism unless the latch 190 is moved from its normal position. For that purpose a series of magnets 192 may be provided adjoining the respective latches 190, a suitable vertical support 193 being arranged to hold the magnets and latches in proper vertically spaced relation.

Each magnet 192 may be connected in series with the trigger switches 93 in the same manner that the solenoid S is connected when an electrically operable dispensing mechanism is employed.

Thus, as shown in Fig. 21, the general arrangement of the wiring diagram may be the same as illustrated in Fig. 12, the connections to tt a tilting control switches being as previously described and the switch C being arranged in the general manner pre riously illustrated. From the switch C the lead 214 may be connected to the magnet 192, the latter being connected to the opposite side of the line 210. At the end of the path of each push '4 rod 174 is a cutout switch B1 corresponding to the switch B, this switch being connected by lead 209a to the magnet D and having its opposite side connected to the lead 210. Thus when a plunger and corresponding push rod move inwardly to 5O turn a dispensing wheel 166 and cause the same to drop playing disks into the chute 172, the corresponding switch BI energizes the magnet D, thus temporarily opening the corresponding switch C and deenergizing the circuit of magnet 192. The circuit remains in this condition until another playing disk is disposed upon the slider I, whereupon the slider and panel 40 are pushed toward the rear of the machine and the switch C is again go closed, in the manner previously described, to con.dition the circuit so that the magnet 192 may again be energized when all of the switches 93 in series therewith are closed.
