Application filed January 10, 1906. Serial No. 295476.

To all lo/ om it may concern:

Beit known that I, SAMUEL D. STUR'GIS, a States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvementsin Perforating- Machines, of which the following is a specifieation.

My invention relates more particularly to perforating-machines used by printers in whichlarge quantities of, paper are perforated. I

The objects of my invention are to provide a simple and easilypperated device which will automatically fee the paper to the per remo ve it therefrom without employing additional means therefor and which. will hold the p Jtper to be perforated on either side of the perfiiratin -knife tightly against, the drum on which t .e-pap'eris fed to the knives, and thereby prevent it from slipping when the some is-being perforated, and thereby prevent the grooves in the drum from becoming filled with paper.

I accomplish these objects by the means described herein and shown in the accompanying drawings, in which- V Figure l is a s 'le elevation of my improved perforating-macnine, partly in section. Fi s. 2 and 3 are end views of 1ny,1nacl1.ine,,.t ie' driving-pulleys being g reincved therefrom. Fig. 4 1s an enlarged fragmentary detail,- partly in elevation and partly in section. Fig. .Sis a side elevation of the perforating or cutting disk, partly shown with one of the annular rubber disks and holding-ring partlybroken away. Fig. 6 isan'edge view of the perforating-disk with the annular rubber rings on either side thereof.. Fig. 7 is a per spective view of the cutter-holding key.

.In the drawings I have not shown the usual table or platform. n-pon'which the device ismonnted nor the surface on which the paper is fed to the perforator, as the same constitu tes no part of my invention.

In the drawings, A represents the frame of the device, in which the device is secured, which consists prineipallyof a hollow. drum B, carrying on the periphery thereof a pluralityof annular grooves B" forthe rece tion of the cutting ed e of the perforatingrnife C; This cutting nife'or dlsk is, adjustably shaft of whic 1 "band is first ;on. The comp n set or shoulder on the securru ber ring mounted on the counter-shaft D, to which 'motiori is imparted through the spur-gears E 1 and F, mounted, respectively, on the coimterand the projecting end which projects through the grooved drum B and to which the drum is keyed by the Set.- screw H. On the shaft is keyed the driving-pulley I, and ad;

J, bynieans ofwhich motion is thrown onto or removed from the machine. 7 These shafts are revolubly mounted in the bearing-blocks K and are adjustable therein by the thumbnuts L. Coiled springs M (shown in Fig. 2) will hold the drum andcountenshaft firmly in their beari s the properly adjusted dis tance a art. l he counter shaft has-a tudinal ey-seat for the reception ofs .bar N This bar has recessesNf in t wardly rejecting edge thereof, the urpose is to receive the downwar ly- 1'07 acingeys, one for each cutting-disk, are placedin 1position within the annular ring P and are eld down into engagement with the s acing-bar N by means of the set-screw 4, and afford means to operly adjust the disks on the counter-shaft. Any number of the counter-she t. They are put in place on theannularring'P-byaneans of the annular securing-ring S, which is internally screwthreaded and adapted for screw-threaded engagement on the screw threaded hub Pon the annular ring P. In assembling to ether the annular ring with the rubber ban s and the'cutting-dislr (shown in Fig. 4) a rubber placed on the ring P, an annular shoulder being placed on the ring therefor, after'which the cutting-disk is placed there- 'anion rubber ring is, then placed on an of in -ring' S, when'the securing-ring with the in place thereon is screwed onto the hub o the annular ring 1 and will se curelly hold the rubber bands and the 'cut -t1ngnife inplace on the hub on the annular ring P. The securing-ring has indentations S there n, forming sockets fora spannerecting lug O on the adjusting-key O. T esev of the shaft G,

e ent- So; these perforatin -knives maybe placed upon wrench, by which the same may be tightly I screwed on the annular ring 'Pl In Figs. 5 and, 6 I have shown thepe'rforating-knife in enlar ed detail, on each side of in their normal position extend outward y i63 which is placed-a ru ber ringR, which rings and beyond the cutting edges of the. perfo- 1o doWnW erdly edges innnediatelyabove the grooved drun'i,

at which point the edges of the knife project beyond the edges of the rubber bands and into the grooves B of the drum n'd perforate the paper. These grooves are -'u'st 'Wideenough' to pern'iit'the entrance thereinto of the cutting edges. that or I 5 tionof the rubber bands on both sides 0 the cutting'edges will contact with the grooved drum and will be pressed baclnvardly by the drum, permitting tliecutting edges to enter into thegroove and prevent any of the paper 'f-romentering therein. When the paper to be perforated is-inserted between the grooved drum and the coi'inter-shalt, will -lirst he get ed by the oiItWa-rdly-prO ectmq' edges 'bf'iil e annular rubber bands and Will, wlihn 2 5 motion is imparted to the machine, be drawn 'therebetween and'will be held in tight i'ric- "tionpal contact between the rubber bands and the drum,- and the cutting edges of the knife WilLPeiforrtethe same. As it passes out from under the counter-shaft the resiliency 'of the rubber "bands thereon will remove the w. paper from the cuttlng edges of the knife and cause the perforated sheet to move Freely away from the OOUI'ltCT-Sl litit without anv Q 5' other device to accomplish this end.
