UNIVERSAL SHEETING MACHINE.

To all whom it may concern:

Be it known that I, HERMAN J. SCHULTZ, a citizen of theUnited States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Universal Sheeting Machines, of which the following is a specification.

This invention relates to a sheeting machine and refers more particularly to a machine for cutting rolls of paper such as wall paper or other types of roll paper which is printed with designs, into equal length sheets, the novelty of the invention lies in the manual regulation that may be had over the sheet lengths to conform with the variance in the length of the design printed thereon.

Fig. 1 is a side elevation of the machine.

Fig. 2 is a side elevation taken from the opposite from Fig. 1.

Fig, 3 is a plan view of the machine.

.Figs at and 5 are details of the ratchet device for rotating the cutter showing the ratchet in inoperative and operative positions.

Fig. 6 is a detail taken along the line 6-6 in Fig. 3.

Fig. 7 is a detail taken along the line- 7-7 in Fig. 3.

Referring to the drawings, 1' is the frame of the machine upon which the mechanism is mounted. t any convenient position in connection with this frame is mounted a motor 2 which drives by means of a belt 3, and pulley 4, a gear 5 through a pinion 6 mounted upon a stub shaft- 7. The gear 5 is mounted upon a shaft 6 upon which is also mounted a roll 7 over which the paper sheet 8 rides in its travel from the roll!) to the cutter. The gear 5 is meshed with a second large gear 10 mounted upon the shaft 11 which also carries a sprocket 12. Sprocket 12 through a chain drive 13 rotates th sprocket 14: pinned to the ratchet wheel 15, both of which are loosely mounted upon the shaft 16. An idler pulley 17 serves to keep proper tension upon the chain. Upon the shaft 6 is mounted a pinion 18 which drives through the chains 19 and 20, the shafts 21 and 22 which carry the rolls 23 and 24:. These rolls serve the same purpose as the rolls 7, namely, to carry the paper sheet in its travel through the machine.

The paper to be sheeted or cut byme-an's of this mechanism may be a roll of wall paper samples which are printed in regular Consequently, if the sheet was to be cut at regular lengths by the common type of sheeting" machine, the positioning of the,

cut would gradually work away from the proper position at the end of the design into the design itself. For this reason it has become necessary to manually control the positioning of the cut so that each sheeted portion will contain a completed design. The paper coming from the roll 9 is fed onto the machine due to the pressure of the feed rolls 25 which contact with the rolls 7 The rolls 25 are mounted upon supports 26, the pressure between the rolls 25 and 7 being maintained by means of a spring 27 and crank 28 maintaining a rotative pressure upon the. pivot shaft 29 which carries the supports 26; Similar feed rolls 30 contact with the bedroll 23 on the opposite end of the machine.

Th proper positioning of the cut is ef fected by causing the fingers 31 which are mounted upon a chain 32 to coincide with the line on which it is desired to cutthe paper shown by the dot-dash line 33. If the operator by means of the control handle 34, keeps the finger 31 directly abovethe line on which he desires the cut to be made, this finger will trip the depending latch 35, which through a series of connections hereinafter described, will properly function the cutter blade 36 to sever the sheet along the desired line 33.

Explaining now the mechanism for controlling the travel of the finger 31. One end of the roll 7 is tapered as shown at 37 and on this tapered portion or pulley runs a belt 38 which drives a similar tapered pulley 39 mounted in an opposite manner to the pulley 37. This latter pulley is mounted upon a shaft 40 upon the opposite end of which is mounted a bevel gear 41 meshing with a similar bevel' gear 42 carried by the vertical shaft 43. This vertical shaft is pivoted upon the frame by means of the support 44:. The bevel gear 42 is connected by a web 45 to a pinion which meshes with a larger gear 4 which in turn is meshed with the pinion d8. The gear 4:? is mounted upon a stub a9 and the gear 48 on a stub 50, both of which are carried by a frame 51 pivoted on the shaft On the stub shaft is also mounted a sprocket 52 which drives through the chain :52, a sprocket wheel 58 mounted on a similar frame 54: pivoted at 54'' A. spacer 56 holds the frames at fixed distance apart and moves with the frames in a parall I directionwith the sheet. The spacer is cut away as shown at 57 so that the operator may clearly see the position the 3i which are fastened to the endless 32. To keep the finger in coincidence r ii the line 38 upon which the paper which is to be cut or the line separating the successive design pattern, it is only necessary for the operator to manipulate the handle 3-1;; which is mounted upon a screw threaded shaft 58 threaded in the lug 59, carried by the support 60 which is mounted upon the frame. The opposite end of the threaded shaft 58 is connected by means an upstanding member 61 to the 5i so that when the handle 34 is turned in one direction the frame member 51 pivoted at l3 will be moved so that the travel of the finger is retarded and when the handle is turned in the opposite direction the linger on the chain will be moved ahead relative to the travel of the paper sheet. it is understood, of course, that the chain in normal operation is timed to trav the same rate as the paper sheet. One, two or a plurality of fingers may be attached to the chain 32 so as to make the cuts at any desired intervals on the sheet, and if sheets are to be made of greater length than the endless chain, it is only necessary to change the size of the sprocket 1a.

in case the threaded shaft 58 has been turned continuously in one direction to conr pensate for the variance in a design so that the wheel 3% has reached a position close to the member 59 or in retarding the lift of the finger the frame has been drawn to an opposite extreme position, it is necessary that there be some additional means for increasing or decreasing the rate o? L 7 travel of the endless chain, so tnat only small variations either ahead or back shad be compensated by the adjustment etiect d y the wheel 34. To vary the rate of travel of the endless chain a transverse shaft threaded at 63 is mounted to bear at one end in the frame 1 and at the other in the central bushing of the web 64. This web is supported by two projecting rods from the side frame of the machine. 011 the opposite side of the web from that into which the threaded shaft 63 is screwed, are hearing sleeves upon which are mounted the rgl guide pulleys 62. The guide pulleys rotate with the belt 38 as it is driven over the tapered pulleys 3'? and 3 To increase the speed of the pulley 39 and consequently v 'haft r0 which through a series of connections explained, dr'ves the endless chain 332, it is only 11 to turn the handle so that the belt is moved transversely onto the larger portion of the tapered. pulley 23? l of the tapered pulley in a similar manner, when the endless chain traveling at too high a speed or it desired to reduce the rate of oi' the Lt er 2 to coincide with the severing line on the wall paper, by turning the handie in the opposite direction so that the is moved to a position shown lil 3, the

travel of the endless chain is consequen ly diminished. in 7 the posithe web 6;- is shown in dotted lines, when it has teen drawn to a position to increase the speed of the end ess chain by means of the screw thread 63 which threaded into the central bushing of the web 64:. This latter compel \tion is un necessary except where the length oi ti wall paper des gn units increase in one direction, fr when one unit is short and the next long successively or where a general of the lengtiis of the she ts to cut will be relatively co stunt, colnpensation can be made by means of the regnlating handle Describing now the manner of effecting verse shaft 67 and is held in a depending position by means of the spring 68. @n the opposite end of the shaft 67 is mounted a trip "4'0 which fits flush against the flat head portion of the latch 71. The latch is pivoted at on an upri ht member 73, the latter being pivoted at .J-. in the frame th machine. fin upright catch also mounted on the frame, is engaged by the hook portion i of the latch. Centrally of the upright member is fastened a link i6 which attached to a siidable trigger 7?, the head of which is contacted by a cam 78 fixedly mounted upon the shaft 16. A. dog 79 is rotatably mounted upon the shaft 16 and has near its end a pawl 80. This pawl is adapted to engage the teeth of the ratchetwheel 15 when released by the catch YT engagin a pin 80 on the pawl. A spring 81 imposes a constant ten sion upon the pawl and the spring 82 maintains a constant pull upon the latch 71.

To explain now the operation of the device, when the finger 31 trips the depending member 35 the shaft 67 is caused to rotate so that the trip 70 is thrown into position Ice llii

shown in Fig. 5. This raises the latch and releases the hook 7'1 of the latch from engagement with the upright catch 7 5. With the releasing of the latch the upright pivoted bar 73 is moved on its pivot permitting the trigger to slide forward and release the pawl 80. The spring tens on upon the pawl immediately engages it with one of the teeth of the ratchet wheel and as the ratchetwheel is pinned to and driven by the sprocket 14, the dog is carried with the ratchet wheel. At 83 on the dog is a pin which projects into the path of the cam so that with its rotation the dog will contact with the cam 78 and carry the cam with it during the remainder of its rotation to a position such as that shown in Fig. 4 where the high portion of the cam contacts and cooks the trigger and releases the pawl from its engagement with a tooth of the ratchet wheel. In recocking the trigger the cam causes the latch to become again engaged on the catch and the trip 70 will resume its position as shown in Fig. 4, at which time the depending member is again in position to be contacted with the finger 31. its the cam 7 8 and the cutter 36 are fixedly mounted upon the shaft 16, when the cam is rotated by being carried with the dog, the cutter will likewise be rotated to sever the paper sheet at the desired position or along the line 38. It will be understood that the paper sheet has traveled so that the line of severance 33 is directly between the cutting blades 36 and 84L when the blade is rotated to sever the sheet. In a like manner successive sheets of the clesired length, are severed from the roll and are fed into a hopper, not shown, at the side of the machine where they are collect-ed and suitably bound.
