'One of 'the l objects v'o'f `"the invention "is' to VSpro-l videy a comparatively inexpensive fmachine v'for accomplishing the sta-ted operation.

AAnother object, lin 'the same "connec-v tion, Vis `to provide ysuch a"machine`thatcan`be operated 4from a'smalll voltrnotor.
`In conventional machines thecuttingknife or blade iscontinuously rotated, andtheadjustment of the blade for different thicknesses'o'f lmaterial requires ithe loosening V'and tighteningof nurne'rT ous'bolts that Yhold the'blade. 'Another 'lbject of thel present invention* is 'to i 'simplify :thefblade structure by providing an intermittently rotating blade and varying the frequency "thereof lfor desired lengths of'material'to be -`out.

'a length of paper li'between the'ngers l2 4and across the edge of'the'blade 5. The lower roller lf3 is preferably rubber covered at 1B, andthe roller'l'd bears thereon to move the paper. I
`Onone end of the shaft vl 'is looselyv mounted a drive lpulley I7 carrying 'on its,'inner"-"surfacelav clutch plate I8. "This-'plate'iaces a complenie'nitary clutch plate I9 0n the shaft 1, and betvven the v p1at,esj|8, i9 is inserted a l'drive disk '20 as shown more "clearly in Figure 3. Thes'ha'ft `1 ls to'be drivenonly When rthere is driving engagernentfbetvveen the plates [8, I'B. vvThe clutchin cludes a series of balls V2i mounted "in the disk ZUand'extending tolboth sides' thereof. The balls are-received in 'a circula-1' groove'22 vin 'a plate I3 and n"rec`e'sses 2 3 in the plate |'9,'the recesses being tapered or reducing in thlckness't'oward both endsfas-ialso shown in'FigurefS. A lug'd, extends outwardly'irom the edge or the disk 2S FigureZ) Land 'permits 'the 'disk Atoloe held scribed. '-Whenthe 'disk is held stationaryg-{tlfieimV tatingfV pulley i158 inerely rolls 'tlie'balrl's 21 infgrove 22 of the stationary disk 20 without transmitting motion to the plate I9 and shaft 1. When, however, the lug 24 is released, the disk 20 is displaced and rolls the balls into the shallower ends of the recesses 23, whereby the plate I9 and shaft 1 are driven. The shallowing of the recesses 23 at both ends permits the plate I9 to be driven in either direction.
The rollers I4 and I3 are supported in a bearing 25 on the frame I, as shown in Figure 1, and the shaft 8 of the roller I3 carries a small sprock-- et wheel 26. A similar sprocket wheel 21 (Fig-` ure 2) is mounted adjacent to the pulley I1. To,-
the base 23 of the machine is attached a pair of spaced guide rails 29 that extend upwardly in the general direction of the sprockets 26, 21 as shown in Figure l. Along the guide rails is adjustably mounted a bearing arm 39 tted at one end with adapted to withdraw said stop means.
a clamp plate 3I (Figure 5), a bolt 32 passed between the rails and a nut 33 on the bolt at the other side of the rails whereby the bearing may be clamped in the desired position along the rails.
The bearing 30 carries a stub shaft 34 on which is rotatably mounted a sprocket wheel 35, and a sprocket chain 36 is passed over the wheels 26, 21 and 35.
Below the shaft 1, the frame of the machine supports a transverse rotatable shaft 31. Adjacent to the shaft 31, there is mounted an electric motor 38 belted at 39 to a wheel 49 on the shaft 31. A smaller wheel 4I on the shaft 31 is belted at 42 to the pulley I1.
Another shaft 43 (Figure l) is journalled'across the frame below the shaft 8 and carries a wheel 44 which is belted at 45 to still another Wheel 46 on the shaft 31. The shaft 43 carries a feed roll 41 over which the paper passes and by which it is delivered to the free rollers I3, I 4. Shaft 8 also carries a wheel 9" driven by belt 44 joining' wheels 8' and 44. The rotation of the roller 8 causes rotation of the sprocket 26 which in turn drives the chain 33.
The chain 36 has a pair of consecutive slotted links 48 (Figure 2) between which is mounted a trip cam 49 for the lug 24. A lever 50 retaining the lug 24 is pivotally mounted between its ends on a pin 5| carried by the frame. The opposite end of the lever is pulled by a spring 52 which normally holds the lever in locking relation to the lug 24, in which no motion is transmitted to the clutch plate I9 and shaft 1. A lug 53 extends from the lever 59 and is engageable by the travelling cam 4.9 to withdraw the lever 5l! from the lug 24 and permit a complete rotation of the shaft 1 in the manner already described. The blade I Il thus sweeps across the edge of the blade 5 to sever the paper. The prompt engagement of the clutch is facilitated by a coil spring .54 joining pins 55 and 55 carried respectively by the plate I9 and disk 2l).
The length of paper that is cut off on each rotation of the blade Il) is determined by the tripping interval of the cam 49 which in turn is determined by the length of the chain 35. For this purpose the length of the chain may be adjusted by inserting additional links between the links 48, or by removing links if the chain is to be made shorter. After the length of the chain has been adjusted, the chain is made tight by proper adjustment of the bearing arm 3G along the rails 29, followed by tightening the clamp 3I-33.
