Description:

My invention relates to a machine for cutting, pasting and folding wall paper.

It is a purpose of my invention to provide a machine of the above mentioned character that is simple in construction and which will measure off a length of wall paper as may be determined by setting the machine -to the length desired, which will prevent operation of the machine after the desired length of paper has been cut and had paste applied thereto, and which cannot be again operated until the machine is reset to cut the same length or any other desired length of paper.

It is a further purpose of my invention to provide a machine of the above mentioned character, which is provided with cutting means for trimming the edges of a roll of wall paper, and which is also adapted for cutting out borders having straight edges, or widths of paper less than the full width of the roll for fitting in corners or around openings, as may be desired.

Furthermore the cutting mechanism is so constructed and arranged that the paper will be cut 'substantially through, but not entirely through, so as to be not completely severed at the cut, whereby the portions of the paper that constitute the trimmings, or cuttings, will remain in place until the paper is removed from the machine after having had the paste applied thereto and after having been folded in the customary manner for easy handling after having had the paste applied thereto. The portion of the paper that is to be removed can then be severed very easily from the strip that is to be used, by merely pulling off the trimmed edge portion, or other width of paper that is to be discarded.

It is a further purpose of my invention to provide a machine of the above mentioned character, into which a roll of paper can be readily inserted and quickly threaded into position ready for having the edges thereof trimmed or otherwise cut, and for application of paste thereto.

In order to accomplish this, means is provided for causing the paper to follow an undulating path, whereby it will be tensioned and engaged properly with the above referred to measuring means and the paste roller, which means can be readily removed so as to place the web, or length, of paper extending from the roll in position over suitable rollers constituting part of the mechanism of the machine, and the means for causing the undulation in the web portion can be readily replaced in position in a minimum period of time without the removal of any large number. of parts of the machine.

It is a further purpose of my invention to provide, a machine of the above mentioned character, in which the paste container, the paste roll and other parts that might require daily cleaning, can be removed from the machine as a unit and also readily replaced in position.

It is a still further purpose of my invention to provide a machine of the above mentioned character with means for determining the length of paper that is to be cut off with paste applied thereto, comprising means for rotating the paste applying roller, measuring means operated by the movement of the web of paper through the machine, and stop means actuated by the measuring means for halting the operation of the means for rotating the paste roller when a predetermined length of paper has been measured off by the measuring means, said measuring means further comprising means for setting the same to measure off any desired length of paper.

Other objects and advantages of my invention will appear as the description of the drawings proceeds. I desire to have,it understood, however, that I do not intend to limit myself to the particular details shown or described, except as defined in the claims.

Referring in detail to the drawings, my ma- 2 chine is provided with a pair of side frame members 20, which are secured in spaced relation to each other in any desired manner, as by means of cross members 21 having spacing sleeves 22 surrounding the same. Said side frame members 2 20 have depending bracket members 23 thereon that are provided with tubular sockets 24 for adjustably receiving tubular legs 25, whereby the height of the machine can be adjusted as may be desired, said legs being held clamped in ad- 3 justed position by means of suitable clamping screws 26.

Each side frame member 20 is provided with a threaded boss 27, which receives a screw-threaded headed member 28, whereby said members 28 are adjustable toward and away from each other.

The inner ends of the members 28 are received in suitable sockets in the end of the shaft 29, whereby said shaft is rotatably mounted between said members 28 on the frame.. The shaft 29 is provided with a threaded portion 30 for receiving the threaded hub portion 31 of a flange 32, a similar flange 33 being fixed on the shaft 29 in any suitable manner at the opposite end thereof, said flange 32 being removable and adjustable toward and away from the flange 33, so as to provide a reel of a width corresponding' to that of a roll of wall paper 34 mounted on the shaft 29 between said flanges 32 and 33. Suitable means can be provided, such as set screws, for holding the flange 33 in position and for holding the flange 32 in adjusted position.

Mounted in suitable bearings 35 in the side frame members 20 is a shaft 36, which forms part of the measuring mechanism. Mounted on said shaft 36 so as to be fixed in position thereon, are roughened or knurled rollers 37, said rollers being arranged at closely spaced intervals along said shaft 36. One end of the shaft 36 has a gear 38 fixed thereon, a collar 39 being mounted between said gear 38 and the bearing member 35, said gear 38 meshing with a gear 40 mounted rotatably on a stationary stub shaft 41 mounted in a boss 42 on the one side plate 20, as will be obvious from Fig. 6. The gear 40 has a tubular sleeve-like member 18 projecting therefrom, secured thereto by means of a flange 19. Said tubular member 18 being thus mounted on the shaft 41 to rotate with the gear 40. Said sleeve 18 has an elongated hub portion 43 of a drum 44 mounted thereon, said drum being detachably connected with the sleeve 18 so that the same can be rotated either with the sleeve or independently of the sleeve by suitable means, such as the thumb screw 46, a collar 46 being mounted on the shaft 41 to prevent disengagement of the drum therefrom, and a collar or head 47 being provided on the other end of the shaft 41 to hold said shaft in assembled relation on the side plate 20. The drum 44 is provided with a continuous thread 48 on the outer surface thereof, the purpose of which will be described below.

The roll of paper 34 is placed on the shaft 29, the flange 32 being removed for this purpose, and after the roll 34 is in place, and the flange 32 has been replaced the web of paper 49 extending from the roll 34 is placed over the shaft 36 in contact with the roughened rollers 37, as will be obvious from Figs. 1 and 3. Said web or paper 49 is also passed over a backing roller 50 forming part of the cutting mechanism, over a paste applying roller 61 and over a cutter bar 62 and a guide bar 53 to the exit end of the machine, in threading it through the machine, ready to be 0 operated upon.

I order to assure intimate contact of the web 40 with the rollers 31, and tension it, so that the measuring mechanism actuated thereby will be accurate in its operation, and in order to have 5 smooth contact of the web 49 with the backing roll 50 of the cutting mechanism, a pair of rollers 54 and 55 is provided located on opposite sides of the rollers 37 and above the same to depress the web of paper on opposite sides of said rollers 0 37 and hold the same firmly in engagement with said rollers 37. The rollers 54 and 55 are tubular members mounted on bars 56 and 57, and said rollers are removable as a unit by quick detach, able connections with the frame, so that the 35 threading of the web 49 in position in the machine is facilitated. The quick detachable mounting for said rollers comprises a pair of side members 58 having the bars 56 and 51 extending between the same and having an upward extension 40 through which the bar 69 extends, said bars 56, B5 and 59 securing said side members 58 together in predetermined spaced relation, being provided with threaded ends for receiving the nuts. 60 for securing the parts in position.

45 Each side frame member 20 is provided with a bracket 61, shown more in detail in Fig. 11, fixed thereto by suitable fastening elements 62, each of said brackets having a hook-like flange 50 portion 63 receiving a lug 64 on a member 58 under the same. Each member 58 is also provided with a lug 65 projecting therefrom, which is engaged by the clamping screws 66, said clamping screws being screw-threadedly engaged with brackets 67 55 on the side frame members of the machine. It will be obvious that the entire frame made up of the side members 58 with the rollers 54 and 55 extending therebetween can be removed by merely unscrewing the two screws 66 and slip60 ping the lugs 64 out from under the overhanging flanges 63.

The roller 50 is made of hardened steel and cooperates with cutter members to trim the side edges of the roll of wall paper and to cut the 65 same in strips of desired width for placing around door and window openings, in corners, and other places where less than full widths of wall paper might be used, and for cutting borders. Cooperating also with the cutting mechanism is a scale, 70 which comprises a cross bar 68, which is secured to upstanding brackets 69 on the side members 20, and serves as a means for holding the side members in properly spaced relation, said bar having a scale 10 thereon that is marked in inches 75 and fractions of an inch in a customary manner.

Mounted between the side members 20 and secured thereto, and serving to hold said side members in properly spaced relation, is a bar 71, which is rectangular in cross section. Said bar 1I may be provided with threaded ends extending through the side frame members 20, with which the nuts 72 cooperate to clamp the bar 11I in position.

Preferably, bosses 73 are provided on the side frame members to reinforce the same at the point ofsecurementofthecrossbar 7. A pair of rods, or fixed shafts, 74 and 71 also project inwardly from each of the side plates 20 on opposite sides of the mounting for the bar 71.

A lever 17 is mounted pivotally on each of the shafts, or rods, 14, each of said levers having a Spointer 11 mounted thereon, which cooperates with the scale 10 in an obvious manner. Each lever also has a curved upper end portion 18, which has a thumb screw 10 screw-threadedly mounted therein, said thumb screws 19 engaging at the lower ends thereof with the rod-like members 75 and serving to hold the levers 76 in adjusted position along the rods 74 and 15, and also serving to exert the desired pressure through the levers on the cutter members cooperating with the roll 50. Said cutter members are rotatably mounted in bearings in enlargements 80 in the bifurcated lower ends of the levers 76, said cutters 01 being provided with beveled edges so as to provide cutting edges, which are not knife edges, being somewhat blunt, but sufficiently sharp to cut the web of paper 49 in cooperation with the hardened roller 50. It will be obvious that the cutters $1, the cutting edges of which align exactly with the tapered ends of the indicator members 11, can be adjusted to any desired position within the limits provided by means of the rodlike members 74 and 15 to trim the edges of the roll of paper as may be found desirable.

While in the ordinary use of wall paper it is only necessary to trim the edges, it is highly desirable, in order to obtain a neat job at door and window openings, to cut the web of paper longitudinally to less width than the normal width of paper between the marginal edges thereof after trimming, and sometimes it is desirable t6 cut a strip off one side of the web and sometimes off the other side of the web, or even both sides thereof. By providing the scale and providing adjustable cutter members that cooperate with the scale, widths of paper of any desired character can be cut on my machine, and in order to provide such adjustable cutter members the bar 71 is provided, said bar 11 being provided to obtain an adjustable mounting for intermediate cutter members that can be moved into position to cut the desired width or strip of paper that may be necessary for a narrower space than the normal width of a roll of paper, and which can be adjusted so as to be entirely out of cutting position when only the edges are to be trimmed, and which can be readily and quickly adjusted to position lengthwise of the scale and into and out of cutting position.

The mounting of each of these intermediate cutter members on the transverse bar 11 comprises a mounting member, such as shown in Fig. 5, having a body portion 82, which has a rectangular opening 80 therethrough for receiving the square rod 71. Said member 82 has a bracket portion 88 extending therefrom terminating in a stop finger 81 extending substantially parallel to the opening 83, and also has a reduced hub portion 88 extending from one side of the body portion 82. Said reduced hub portion 88 receives the tubular body portion It of a lever having an arm 90, having a cutter member 91 mounted in suitable bearings in the bifurcated lower end of said arm 90, and having an arm 92 extending therefrom in substantially the opposite direction to the arm 90, which is adapted to engage with the stop member 87 to hold the cutter member S1 in elevated position, as shown in Fig. 1, and as shown for one of said cutter members in Fig. 3.

When it is desired to engage a cutter member with the web of paper 49 it is only necessary to slide the tubular portion 89 thereof lengthwise on the hub portion 88, so as to disengage the arm 92 projecting rearwardly therefrom, from the stop 87, and then replace the lever in position by sliding in the opposite direction on the hub portion with the rearwardly extending arm 92 thereof above the stop 87. The arm 92 has a thumb screw .4 screw-threadedly mounted therein, Swhich can then be adjusted to engage the upper face of the stop 81 to cause the cutter member 91 to engage the web of paper with the desired pressure. Each cutter member is provided with an indicator, or pointer member, 93 cooperating with the scale 70, to indicate the position of said cutter member, said pointer, or indicator member, aligning with the cutting edge of the cutter member 91. Said thumb screws 84 also serve to hold the cutter members in adjusted position on the bar 71.

Pivotally mounted on the shaft 75 are links 94, which pivotally carry a rod-like member 95 having sleeves 91 rotatably mounted thereon, on which the rollers 96 are mounted. Mounted in fixed position on the links 94 are the arms or links 98, said links 94 and 98 together forming a bell crank lever. Pivotally mounted in the outer ends of the arms 98 is a rod-like member 99, which is located above the rod-like member 95.

A bracket member having a hub portion 100 is mounted on the rod-like member 71, being adapted to be fixed in position thereon by means of a set screw. Said bracket has an arm 102 extending therefrom, on which is pivotally mounted a lever 103 having a handle portion 104 and a hook-like end portion 105, which is slotted to receive the rod 99 having a plurality of recesses in the upper side of the slot for adjustably receiving the rod-like member 99. It will be obvious that by adjustment of the handle member 104 the lever 103 can be adjusted to vary the position of the rod-like member 99, and thus the position of the rollers 96 and thus the pressure of the rollers on the web 49, pressing said web against the paste roller 51. The pressure of the rollers 96 can be completely relieved and the same lifted off the web of paper so as to space the same from the paste roller to permit threading of the web of paper into the machine by the opposite movement of the handle member 104, which will cause the rod-like member 99 to drop to the bottom of the slot and be lifted by means of the hook-like end portion i05 of the member 103, to thus move the rollers 96 away from the paste roller 61. A post 101 is provided on the member 100, with which a loop-like member 101' on the handle is adapted to engage to hold the lever in such position that the rollers 96 will be elevated. The paste roller 51 is mounted for rotation within the paste receptacle, or pan, 106, which, preferably, has a sloping bottom so as to place the lowest portion 107 thereof substantially below the axis of rotation of the paste roller 51. 75/Said paste roller is mounted to be removable as a unit with the pan, said pan being, preferably, provided with side walls 188, to which supporting members 108 are secured in any suitable manner in fluid-tight relation, as by means of the bolts III and nuts III. Said supporting members 100 are provided with bearing portions 112 for the shaft portions 11I provided on the roller S1I, said roller being, preferably, hollow and having end walls 114 on which the shaft portions I 13 are fixed. The shaft ill can extend entirely through the roller if desired, or stub shafts can be utilized. Fixed on one of said shaft portions II is a pinion 115, said pinion being removable along with the roller and the shaft and the pan, so that the entire unit can be removed for cleaning paste off the same, when this is desired, the unit made up of the roller, paste pan and driving means therefor being readily transportable into position under a water faucet for washing the same off when this is desired.

The supporting member 109 is also provided with upstanding supporting members, or brackets, S11 and II1 thereon. Said brackets II support the bar II8 for removing excess paste from the surface of the paste roller 1I, while the brackets 11 support the cutter bar 52 having a slot I19 therein, with which the- usual hand cutter tool cooperates to cut off the length of paper at the point where the same overlies said slot II. The pan member 101 rests at one end thereof and along its inclined bottom on the top surface of a bracket 120 provided on'each side frame 20 of the machine. Any suitable means for detachably fastening the pan in position, so that it and the parts carried thereby will not move out of position, may be provided, such as the ears 121 thereon adapted to receive a thumb screw 122 engaging a suitable threaded opening in each side frame member 20.

Means for driving the paste roller is provided comprising a pinion 123 rotatably mounted on a stub shaft 124, which is rotatably mounted in a suitable bearing 125 in one of the side frame members 20, and which is provided with a collar 126 pinned thereto for holding the same in position in the bearing. Said pinion 121 is located toward the end of the machine carrying the roll of paper from the pinion I II, so that upon pushing the pan 101 into position these pinions will mesh. A bearing 121 is also provided in the side member 120 for a shaft 128, which has the pinion 129 fixed thereto, meshing with the pinion 123, and which has a sprocket wheel 130 fixed thereto, over which the sprocket chain 131 operates.

Said shaft also has pinned thereto the hub portion 132 of a crank 133 having a handle 134 thereon. Thus the shaft 128, and through the pinions 129, 123 and 115, the paste roller 51, are rotated by rotating the crank by means of the handle member 134.

The sprocket chain 131 also operates over a sprocket wheel 135, which is mounted on the reduced end portion of the roller 50 to rotate with said roller, said reduced end portion being indicated by the numeral 138 and having a ratchet wheel 131 mounted thereon, which is shown more clearly in Fig. 9. Both the roller 50 and the paste applying roller 5I rotate in a clockwise direction as viewed in Fig. 3, and the ratchet teeth are sc positioned on the ratchet wheel I31 that such clockwise rotation of the shaft portion 136 and thus of the roller 50 will be prevented by engagement of the tooth, or pawl, 138 with said ratchet teeth. The pawl 138 is carried by the enlarged body portion 139 of a lever 140, said pawl, or tooth being, preferably, of hardened steel and being detachably secured to said body portion 131 by a fastening element 141. The lever 141 is urged toward a grooved stop bracket 142 provided on the frame member 20 by means of a coil spring, or similar resilient means, 143 engaging the headed fastening element 144 on the body.portion 139 of the lever and having the other end thereof secured to the frame 20 in any suitable manner as by a bolt 5I. The lever is mounted on a pivot 145 and is provided with a handle member 146 for lifting the same against the tension of the spring 143 when this is desired. Said lever 140 is provided with a downturned end reduced portion 141 forming a finger, the purpose of which will be described below.

Screw-threadedly mounted on the thread 48 on the drum 44 is an internally threaded ring member 148, which carries a bracket 149, upon which a block 10I is mounted, having an opening III therein adapted to receive the depending finger portion 141 on the lever 148. A scale 152 is slidably mounted in a corresponding recess 153 in the block 150, and an adjusting screw 184 engages ,said scale I52 so that the zero point on said scale can be accurately aligned with the center of the opening 1I1. The depending finger 141 also cooperates with the scale 152, which is provided with a set screw 155 mounted in the slot 156 for fixing the same in adjusted position, and the. scale provided on the scale member 152 is calibrated in feet.

The drum 44 is, of course, rotated by means of the shaft 36, carrying the rollers 13 and the ratio of the gears 38 and 40 is such that each time that the rollers 37 rotate sufficiently for a foot of length of the web 49 to pass thereover, the drum 44 will make one turn and accordingly the marks on the scale indicate one turn of the drum, which equals one foot of length of the web 49 passed over the measuring rollers. A scale is also provided on the face of a ring 115 mounted on brackets 116 (see .Figs. 1 and 2) with which a pointer 157 mounted on the drum 44 cooperates, said scale dividing the ring 116 in twelve parts to thus indicate one-twelfth. of a turn of the drum 44, or inches of length of the web 49 passing over the measuring rollers 31.

In order to cut off and apply paste to a desired length of paper from the web 49, the web is cut off at a suitable matching mark, by running a cutter transversely thereof over the groove IIs on the cutter bar 52. These matching marks are dots or similar markings provided to indicate the proper places to cut off the paper, printed thereon, so as to enable the paper hanger to match the pattern on adjoining strips of paper. With the paper in this position the thumb screw 45 is turned to release the drum 44 from the sleeve 18. The lever 140 is then lifted to disengage the finger 141 from the opening 151 and the drum 44 is rotated on the sleeve 18 until the desired length of paper to be cut off is indicated on either the scale 152, or the scale 152 and the scale on the member 115, if a different amount than an even foot is to be cut off. The exact alignment of the finger 141 with a mark on the scale 152 is possible S due to, the provision of an indicator 158 on the finger 147. However, the scale on the ring 175 is so calibrated that when the "12" mark on said scale is in alignment with the pointer 157, the indicating member 158 will be exactly aligned with a foot mark on the scale 152.

After the proper adjustment of the scale has been obtained, the thumb screw 45 is tightened to secure the drum 44 to the sleeve 18 to rotate in unison therewith. Then, as the paper is drawn through the machine by rotation of the crank 133, the drum will be rotated one turn for each foot of paper passing over the rollers 37 and, of course, over the groove or slot 119 in the cutter bar 52. The finger 147 will ride along on the surface of the scale member 152 adjacent the scale provided thereon until the shoulder 159 thereon is reached, whereupon said finger 147 will drop off the scale member 152 and into the opening 151. When this takes place the tooth, or pawl, 138 constituting a stop member, will engage between two teeth of the ratchet wheel 137, halting rotation of the shaft 136 and of the sprocket wheel 135, thus stopping rotation of the sprocket wheel 130 and the paste roller I1 also.

The web 49 is now ready to be again cut off by means of the usual hand tool run over the cutter bar 52 over the slot 119. After this has been done the paper is again ready for measuring, if the proper match mark is in position; and if not, then the finger 147 can be lifted out of the opening 151 and the mechanism rotated sufficiently by means of the crank to bring the match mark in proper position. After this has been done the drum can be released from the shaft 41 and the measuring mechanism controlling the stop reset in the manner previously described.

. After the web of paper 49 passes over the cutter bar 52 it passes over the curved surface of the guide member 53, which constitutes the tubular portion of one of the members for connecting the side frame members 20 to each other, a rodlike member 21 extending through the same.

Said member 53 is located immediately above the table 160, the plate side of the web 49 being downward as it approaches the table 160, which will cause the same to adhere to the table and fold thereon in a well known manner. Said table 160 is suspended from the tubular member 53 by means of brackets 161 having hook-like portions 162 extending around the tubular member 53.

Fingers 180 are provided to guide the web 49 from the roll 5 to the cutter bar 52.

The machine as above described, is suitable for cutting widths of wall paper of any desired dimensions and for trimming the edges of rolls of paper, but inasmuch as most wall paper borders are printed four to the roll, that is, four borders arranged longitudinally beside each other lengthwise of the length of paper, additional cutter members are necessary to cut out all the borders at the same time. In order to provide for such an arrangement, the machine may be modified 5 as shown in Figs. 12 and 13, in which a portion of the paste roller 51 is shown and the backing roller 50 with the web of paper 49 in position thereon. The cutter members for trimming the edges are mounted on the members 76 in the 6 same manner as previously described, and the intermediate cutter members on the levers,90 are provided on the square bar 71 in the same manner as previously described.

SHowever, instead of providing the scale member 6 70 on the bar 68 shown in Pig. 1, a rectangular bar 68', serving both as a mounting for the additional cutter members and as a scale, may be provided, the same being quick detachably mounted in upward extensions 163 on the side 7 frame members 20'. Any suitable form of quick detachable mounting can be used, a slot 164 being shown for receiving the member 68', and thumb screws 165 being provided for securing the same in position in the slots 164. The cutter members 7 and the mountings therefor are similar to those described in connection with the intermediate cutters, comprising a mounting member 82', similar to the member 82, upon which the lever 166 is rotatably mounted, the same having a rearward extension 187 having a thumb screw 84' mounted therein engaging with the finger 87' for holding the cutter members 168 in adjusted position and in cutting engagement with paper in a similar manner to the thumb screw 84, said extension 167 engaging under the finger 87' when it is desired to hold said cutters out of cutting position. The lever 166 has a bifurcated lower end portion, in which the cutter member 168 is rotatably mounted, said cutter I18 being similar to the cutter 91 previously described.In cutting borders, preferably, four of the cutters 166 are mounted on the rod-like member 68', in such positions as to align with the edge portions of the border where cutting is to take place.

These, together with the edge tiiiniming cutters 8 1 and the intermediate cutters 91, can be so arranged as to cut the four borders out of the roll of paper at the same time. It is preferred, instead of merely elevating the cutters 168 out of cutting position, to remove these entirely when the machine is not being used for cutting borders. This can be done by unscrewing the clamping screws 165, removing the bar 68' and sliding the cutters and the mountings therefor off the bar and then replacing the bar 68', using it merely as a scale. The cutter members 168 do not have to be provided with pointers to operate on the scale for cutting borders, as the borders can be cut without the use of a scale, but If desired, pointers can be provided on the body portions of these cutter members to cooperate with the scale on the member 68'. The carriers 90 and 76 for the cutter members are, however, provided with pointers similar to those previously described, but of different siape and length to cooperate with the scale on the member 68', which will be in a different position than the scale 70, these being indicated by the numerals 71' and 93' and corresponding in function to the pointers 77 and 93.

Referring to Fig. 2 it will be noted that the table member 160 can be swung on the hook members 162, so that the brackets 161 will extend upwardly instead of downwardly from the tubular member 53 with the table in an inverted position, serving as a cover for the mechanism, so as to make the same.more compact for carrying pur;5 poses. A handle, or handles, of suitable character (not shown) may be provided on the bottom side of the member 1.60 for convenience in carrying the machine, the legs 25 being, of course, removed when the machine is to be disassembled 0 for carrying purposes.
