PUNCHING AND CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,332, dated February 13, 1883.

Application tiled May 3, 1882. (No model.) Patented in England July 25, 1882, No. 3,537.

To all whom it may concern :4

Be it known that I, ETIENNE SALOMON, of the city of Montreal, in the district of Montreal and Province of Quebec, in the Dominion of 5 Canada, have invented certain new and useful Improvements in Punching and Cutting Machines; and I do hereby declarer that the following is a full, clear, and exact description of the same. Y 1o This invention relates to improvements in machines for manufacturing metal Washers,

hinge-plates, metal checks of all kinds, and different descriptions of articles generally cut v from a metal plate and requiring to -he after' r 5 ward punched or perforated:

Its object is to peri'orm the work of cutting and punching in one operation, to flatten out all ragged edges, and to turn out an article Iinished in every respect and ready for -the use to which it is to zo be applied.

` My invention includes, also, a selffeeder, which enables me to operate much more quickly than can be donewith the present hand methods, besides insuring perfect accuracy in cntting and punching and avoiding all Waste of material.

ln the following description I shall allude only to the'manufacture of washers, (which by my machine will be certain to have the hole 3o always punched exactly in ther center;) but this is only for purposes of shorterexplanation,

and must not be considered as confining ine to such class of articles alone, as by a simple change of dies and punches I can adapt my in- 3'5 vention to a great variety of uses, as already mentioned.

In the accompanying drawings, Figure l is a side elevation, partly in section, of my machine; Fig. 2, a iront eleva-tion of same; Fig.` 4o 3, a back sectional elevation taken on thelne erating self-feeder; and Fig. 7, a detail of de-A vice for imparting motion to feed-lever.

Similarlettersof referenceindicatelike parts larly descri.bed,) and on their rear ends gearwheels G and H. These gear-wheels inter- Amesh with a small pinion, I, mounted on a 6o short shaft, K, (journaled in the frame,) which also carries a ily-wheel, L, and pulley l, cast integral with each other. The pinion I and ily-wheel L have holes cut in them, in which two or more pins, M, lirmly txed'to a grooved 65 collar, M, mounted on the inner end of the shaft K, work, as will be seen clearly in Fig. 1. This mechanism forms a clutch for throwing the moving'parts ofthe machine in and out ot' gear with thefly-Wheel and pulley; butits par- 7o ticular construction is not necessary to the working of my invention, as any suitable or ordinary clutch may be used in its stead.

The collar M is formedwith a suitable camgroove, m, in which a pin, N, is thrown when V it is desired to withdraw the pinst' from their bearings in the hubof the iiy-wheel L, and thus stop the machine. The pin N is carried onthe upper end of a skeleton pitman, N', as shown in Figs. 1 and 3, and a small roller, n, 8@ on this pitman impinges on the periphery of a' pulley or cylindricalprojection, H', cast in one with the gear-wheel H on its inner side, said pulley having an indentation orV recess, h, formed in its rim, into which the roller nfalls by the means to be described at every complete revolution of the gear H, and thus holds the pin N firmly in the cam-groove m, and as this cam-groove works round upon the pin N- the pins i i are drawn out of the hub of the 9o fly-wheel L and the Workingof the machine ceases.` vTo withdraw the-roller n from therecess In, a lever, O, pivotcd at o to the frame, connected at one end to thepitrnan N', and

provided at the other with a counterbalance- 9 5 weight', O', is raised at the counterbalance end by depressing a treadle, O2, connected to the lever O by a short arm, O, and consequently lowering the end which is connected to the pitman N', and releasing the rollern from the recess h and the pin N from the grooved collar M, which latter is thrown againinto gear with the fly-wheel and pulley by pressure exerted on its end by one or more, spring-levers, P P, pivoted to the frame, as shown in Figsl and 3.

The cani E, carried bythe shaft O, is for the purpose of raising and lowering the punch E', which first cuts the washer from the strip of metal, and isV shown in Figs. l and 4. e is a cam-groove of the configuration indicated in Fig. 4, in which works a roller, e', mounted on the end of a stud, c2, adjustuhly secured in a slot, en, formed in aslide, Q, rnnniugin guides Q. Q', bolted to the front ofthe machine.

To the lower end ot' the slide Q the punch or cutter E is secured by a set-screw, r, orother means, which will permit of its heilig removed and another one substituted. This punch and part of the slide Q, are made hollow to allow of the center pieces eut from the washers by the lower punch, about to be described, to pass upward and out onto a chute, r', which couveys them to a scrapbasket, as shown in Figs. l and 2.

Thecaln F, described as mounted on the front end of the shaft D, serves to raise and lower thepuneh R,which cutsthecentral hole through the washer after it has been formed and forced by the punch E down to the bottoni ot' the die-bloclr l. This punch lrt is secured in the upper end of a slide, S, working in guides S' S. In the cam F is formed a eamgroove,f, in which works a small roller, f', mounted on a stud, f2, adjustably secured in a slot, f3, formed in the slide S, all arranged in a manner similar to that described for the cam E. The die-block R is carried in the frame A in any suitable manner, and is arranged to allow the punch E to follow the washer, after it is cut, clear down to the bottom of its matrix, so that this punch may press and flatten out the washer, and at the same time hold it firmly while the punch lt comes up and cuts the center hole.

Through the die 1l', at the bottom of the matrix, a slot, r2, is formed, iu which an ejector, T, slides, so thatat cach operation the finished washermayheexpelledtherefrom. Thisejeetor is operated by a lever, T', connected thereto and pivoted to a cross-head, T2, in the frame, (its pivot-pin being changed to different holes, so as to lessen or increase the throw of the ejector and adapt it for varying sizes of work,) and its upper end is provided with a small roller, t, and worksin a cam-groove, C,formed in a collar carried by and revolving with the shaft C. This device is so arranged as to be timed to act when the cams have withdrawn the punches from the die-block.

I will now describe my newly-invented devices for feeding the metal plate from which the washers are to be cnt forward to the punches and die.

The gear H, mounted on shaft D, has its outer face formed with a cam-groove, h', in which works a small roller, h2, carried by a short spindle, h3, which slides in a curved slot, u, formed in a standard, U, bolted to the bedplate of the machine. The spindle 71,3 has also attached toit one end of a lever, U', the opposite end of the latter heilig pivoted to a vertical rod, U2, which carries at its upper end a pawl, n2, working in a ratchet, V, mounted on a shaft, V', extending from back to front ot' the machine, and snitablyjournaled. Toward the front, and in a line with the punches and die, this shaft V carries a roller, V2, and atits eXtreme cnd is provided with a bevel-gear, c, which intermcshes with a similar gear, e', on the end of a counter-shaft, V3, extending across the front of the machine through a similar pair of gears, c2 c2, which serves to rotate another roller, V4, at the opposite side. Immediately above each of these rollers V2 V4 are placed other rollers, V5 V6, of like nature, carried by suitable brackets, all as shown in Fig. 2 and 6, and between these double rollers` the strip or plate of metal from which the washers, Src., are cut is placed, and they serve to feed the saine forward to the punches and die at regular intervals with the other oper-ae tions. The length of feed is regulated by sliding a block, W,(shown particnlarlyiu Fig.7,) forward or backward in a slot, w, formed iu the -lerer U', a shortbolt, w', also working along a straight slot, u2, in the standard U, the parts being fitted loosely enough, (but tirmly,) so as to allow the spindle h3 to at all times follow the curved slot c, although the radius from lthe bolt w may be changed. It will be seen that as this radius is altered the number ot' teeth on the ratchet V .embraced by the pawl a is increased or lessened, and accordingly thelength of feed of the material to be operated upon can be varied in this manner to suit different classes of work.

Vhen my machine is to be used for cutting wa shers, &e.,from scrap or metal plates ot'sizes and shapes which will not permit ot' my seit'- feeding attachment being worked to advantage, the same may be removed and the feeding he done by hand.

The operation of the machine may be described as follows: Power is communicated to the pulley l through a belt in the usual inanner, and the pinion I and grooved collar M being in gear, as described, rotary motion is im parted to the gears G and H, which in turn revolve the shafts G and D and vcams E and F. These cams are arranged in relation to the gears as shown in Fig. 4, the cam E heilig there indicated as havin g revolved sufficiently to bring its longest surface (marked 1) to bear on-the roller e', affixed to the slide Q, so as to throw the punch E (which performs the iirst operation) to the full extent of its stroke, or down to the bottom of the die-block It', as shown in Fig. l. The punch B is then midwayin its upward stroke by reason ofthe roller f', (through which the slide S and punch l IIO the punch It up through the washer (thus cut-` tingthe central hole) and vinto the hollow formed in the punch E', driving the waste piece before it. These waste pieces are forced out through a continuationv of the hollow space in the slide Q one by one, and roll down the chute 1",as already described. The cams con- -tinue to revolve, and when their shortest surfaces (marked 2 and 5) bear on the respective rollers the punches are Withdrawn, and the cam-groove C operates on the end of the lever 'l" and forces the ejector T into the slot r2 at the bottom of the die-block R', and eXpels the iinished washer. Simultaneously with the action of this ejector the cam-groove h on theouter side of the gear H presents its shortest side, 6, to the roller h2, and raises the same and the inner end ofthe lever U', and consequently draws downward the vertical lever U2,pivoted to the outer end of U', thus causing the pawl u to rotate the ratchet V, and, through the shafts V V3 and their miter-gears, also ref volvesV the feedrollers V2 V4, which thus feed the metal plateforward the required distance to allow another washer to be cut by the next strokes of the punches. Immediately after one washer is completed and expelled from the die-block and the plate again fed forward the machine stops by reason of the roller u falling into the recess h on the pulley H', and the consequent holding of thepin Nin thecam-groove m, which withdraws the pins t' t' from the hub of the fly-wheel and driving-pulley, as already described. t is therefore necessary to depress the treadle O2 to release the roller n and withdraw the pin'N from the cam-groove, so that the spring-levers P may again throw the pins-M into the holes in the ily-Wheelhub, and the operation of cutting the next washer proceeds. When, however, it is desired. to proceed with the operation continuously, the treadle O2 may be kept always depressed, or the action of the counter-balance O overcome or prevented by any other suitable meanssuch as a locking-stop, Sto. The roller 'n will then ride over the recess It, and a continuous operation is insured. Y

Should it be so desired, the gear H may be made plain on its outer surface and a separate cam be mounted on the shaft D for the roller hzrto Work in; but I prefer' the arrangement shown and described herein.

In view of the state of the art, and-partly cf English patent to Hay, N o-. 1,223 ot'iSSMId'o not wish to claim, broadly, the useof a descending punch for cutting the washer from a plate and an ascending punch for making the central hole, said punches being operated through Y slides worked by horizontal geared shafts, as

I am aware that washers have been made by such mechanism; but in none of these machinos has it been possible to so time the operations as to enable the upper punch to out the washer and then press it ontflat on the bottom of the die-block before the lower punch ascends to out the central hole. Thisserious deciency has been caused by the use of links operated upon by the horizontal shafts to raise and lower the slides carrying the punches.

Again, in these machines no means for adadjusting the throw of punches eft'ectually overcomesall these objections.

Having thus described the construction andv operation of my invention, I beg to state that what I claim, and desire to secure by Letters Patent, is as follows:

l. In a machine for cutting and punching Washers and like articles, the combination of the cams E and F, of s nbstantially the configuration shown, and mounted on shafts C and D, rotated through pinion I and gears G H, with rollers e'f', adjusting-screws c2 e3 f2 f3, slides Q and S, and punches E and R, all arranged and operating substantially in the manner and for the purpose specilied. 4

2. 1n punching and cutting machines, and in combination with the punches and the dieblock It', having the recess r2, the mechanism for operating said punches in the manner set forth-that is to say, forcing the upper punch downward after it has cut out the Washer,

carrying the washer with it and firmly pressing it on the bottom ofthe recess r2, and holding it there until after the lower punch shall have ascended and punched a hole therein.

3. In a machine for cutting and punching washers and other like articles, the combinationwith the die-block R', having slot r2, of the ejector T, automatically operated by pivoted lever T, receiving motion from a cam on the shaft C, which operates one of the punches so as to automatically expel the nished washer without stopping the machine, substantially as described.

4.. The combination, with the pulley H', cast in one with 'the gear H, and having recess h, of the roller u, carried by skeleton pitman N', pin N, grooved collar M, and a clutch for engaging with the hub of the driving-pulley, and a system of levers for withdrawing said roller from said recess, and means for returning the clutch, substantially as and for the purpose set forth.

5. The herein-described self-feeding mechanism, consisting essentially of the lever U', operated by roller h3 and a cam-groove on the gear H, vertical feed-lever U2, pawl u', ratchet V, shafts V' V3, geared together, and the rollers V2 V4 V5 V?, arranged substantially as de scribed, for the purpose specified. ,t
