Similar letters indicate corresponding parts in all the figures.

My invention relates to organized machinery for making eyelets from planchets or disks of metal by a number of consecutive operations upon the separate pieces, each tending to develope the eyelet shape more and more, and finally deliver the eyelet completely formed; and to a special mechanism for transierring and presenting-the pla-nchet, or a separate and detached.- piece of metal in its diiierently-developed forms, to the several punches and dies or instruments by which it is converted into an eyelet, in lieu.

of the means for present-in g and transferring afprtied by the continuous strip in the Letters Patent hereinafter referred to.

My invention consists, first, in the combinaafter described.

dies and punches, for the tiona-nd arrangement. in an organized machine of the several sets of punches and dies or instruments for on Ipi'ng, intermediately dinning, shaping, cutting out, and delivering eyelet-s complete from a plane-hot or anism for transferring and presenting as sepaatc pieces,'-the varlously developed forms of the. planchet, as hereinafter described. Secondly, mvinvention consists in combining, and arranging, with such organized machine, a cuttingpnnch and die or instruments,and a transferring device ibrcutt-ing apd do]ivering planchets thereto,- to be o 'ierz'itcd upon consecutively, as her'eiir Thirdly, my invention consists incon'ibiningand arranging, with a punch and die for shapiI-Ig the flange of the eyelet, mechanism which, in. addition thereto, exerts a supple mental pressure to swa ge and reduce the thickness of the flange to approxiIna-tethat of the body or opposite end of the eyelet, as herein specified.

Fo'iu't-hly, my inventionconsists in combining,

in an organized machine for, making eyelets from planchcts or disks of metal, asupplemental punch and die or instrument for finally trimming the edge of the eyelets'flange allroundwith its body, as hereinspecified.

Fifthly, in the'usc of an elastic carrier that will receive and present the various wrought forms of the planchet, and in combination'ivith an endless belt or band' that. will forward the carriers at proper intervals to the several sets of be performed thereon,-

as described. Sixthly, in supplementing. the

operations required for making eyelets such asare known to the trade and to the public, by

certain other operations upon the flange, in virtue of which the eyelets are greatly improved.

To enable others skilled in'the art to make use of my invention, I will proceed to describe the sam In the drawing, consists of a table, T, with suitable supports T, and three :uprig S S S for the-sliding plungers H H, in which is held the series-oicutting-and-fonning punches E E, E, beneath which, on the tab; is arranged the series of dies G ,G ,G-",&c.,'which cooperate withsaid punches in making eyelets; By t-he'method employed the first operatioli is Erica,

disk oi" metal, with the mech vertically and evenly several operations to the-frame of the mechine stands, 1, with bearings at the topyi'or the dri ing-sha-itl), and vertical guides went the planchet or separate piece of metal from the sheet. This is performed by the first set-of the punches and dies E 'G, Figs. 4, 6, 7, and 8, the sheet m being presented and fed to the same automatically, as hereinafter explained. The second'operation is to convert the planchet or piece into the shape of. a' cap or. a tube, with one end closed, and is performed by the punch l and its die G The two dies G and G, as shown in Fig. 4, are elevated from the table in the block J, and the first which cuts the pianchet is elevated above j the second, which forms the cap, so that, between the under side or delivery of the first, G, and the top oren'trarce of the second, G there is a passage-way by which the planchets may be transferred and delivered singly from the first die to be operated upon by the second by means of a transferrer, h, on a rod, 1), Fig, 14, which .is operated by the lever'l? from the cam n on the driving-shaft. This passageway 1) is of a depth only to admit of the passage of a single planchet at a time, which is deposited from the die G, like a in front of the transierrer h, by which it is pushed forward and deposited in, the round guide at the entrance of the die G where it is operated upon by the punch E and carried through the die G and formed into a cap, 2, Fig. 8, and deposited in another'transierring mechanism or device, which transfers it to the remaining sets of punches and dies. This transferring device is shown clearly in Fig. 4, and in detail in Figs. 5 10, .11, 12, 13, and consistsofa series of carriers, k, on an endless belt or band, 9, supported and moving on two carrying-rollers, U L the latter heing-providedwith a ratchet-and paw j, by which an intermittent movement is given to the apparatus through the connecting and sliding rods :0 from the cam I on the drivingshaft. These carriers are arranged at thesame distance apart on the endless belt as the distance between the several sets of punches and dies E, G, &c., with which they co-operate, and sot-hat the top of the carrier shall pass immediately un- :der the second die G and receive from it the cap,2, Fig. 8, of metal as it is delivered therefrom and carry it between the next set, viz., the punch E and the performed, which, j ,contraeting the cap at its closed end, as shown die G when the third operation is as represented, consists in in 3, Fig. 8; and after this operation is completed the cap 3 is, by the ascent and withdrawal of the punch from the die, assisted by the upward pushingof the'clearer kfrom beneath, withdrawn from the die and deposited again in the carrier,

by the next movement of which the cap 3 is car- I ,ried to the next set of instruments, viz., punch and die it] and G, by means of Whlch the contracted cap is wrought into its complete-eyelet; shape, and by the same means is returned to thecarrier and again transferred to thenext set of instruments, by which the closed end or bottom ispunched out, and in the same manner to the next set of instruments, where the flange of the eyelet is trimmed to the proper size and evenly all round with the body of the eyelet, To rendenthe action of the carriers as positive and accurate as'possible the belt or band should be I of sheet metal, with one edge notched to fit a correspondingly-shaped flange of the carryin roller 0, and the-carriers may be secured to such a belt by rivets passing through a projection on each side,- as shown. in Fig. 11. The carrier K i is a receptacle'calculated to raieive the planchet or separate piece of metal of the various forms of development and transfer and present the same from one set of instruments or devicesto another, for the successive operations to be performed. It consists of an elastic socket, which maybe made of a metallic shell, K, having an India-rubber griper, t, Figs. 10 and 11, that will gripe and hold the separate piece of metal after it has been formed into the cap 2, Fig. 8, by the secondoperation, and, by the movement of the endless belt, carry and present the pieceZ to the next of the sets of punches and dies, and, after.

the operation is performed upon the piece, will receive it from the punch and die, and carry and present it to the next set of instruments; and so on until the final operation is performed, when the completed eyelet'is delivered into a common receptacle in a mass. In Figs; 10 and 11 the griper t is a rubber'washer cut quartering from the hole in the center, as shown inFig. 11, with its outer edge firmly held between the twoparts of the shell K, which screws together and pinches it. The elastic four quarters of the rubber wash er permit the passage of the piece of metal of the eyelet-through the same when carried downward to the die by the punch, andarrest and remove the piece from the punch as the latter is withdrawn, when the operation is complet.

ed, and hold it in position to he presented to the next of the seriesof punches, when carried bel-ieath it by the next movement of the endless 'belt. Instead of the rubber griper, as

described, the shell K itself may constitute the griper, like that of the construetionshown in Figs. 12 and 13, by making it in two vertical parts divided at the line 9- g, and having a recess, 1', with a wider upper and narrower lower projecting lip orilange, 0 o, to arrest and hold the'separate piece 4, and making the grip elastic by a surrounding band of India rubbeiyn, on

the shell, and having the shell secured bygneans of a dovetail recess at itsbottom end to the endless belt, so as to slide laterally'on a plate, u,

riveted to said belt,as shown in Fig. 13, by which construction, together with the bell-shaped entrance of the carrier- K, the punch may readil'y enterwith the piece to be operated upon, carry it through the shell or socket into the die below, and, returning, leave the piece inth'e ca'rrier or socket between the two lips or flanges where, by the elastic action of the rubber band a, it is held in position it by the movement of the endless belt. Thus, by means of the series of carriers or transfermg device, separate piecesof metal of diii'erent form may betran sferred to successive mstruments of a series for the performance of a number'ofcon seontive' operations upon the same piece, each der to be presented to the next punch of the series whencarried beneatha separate machine or place, and the planchetsv set is a cutting-punch and die, E G and cuts Y 9, in which the forming-punch'E asin 3, Fig.8, may in some cases be dispensed the shoulder of the punch and the face of the Figs. 6 and 7, theplanchet is cut and the eyelet completed therefrom by a series of six sets of punches and dies and six operations, illustrated by the several shapes the metal is made to as-' sume in Fig. 8. But a greater or less number of. punches and dies may be employed, according'to the kind or nature ofthe .metal to be punched and the length of eyelets-to be produced; also, the cutting of the planchet may be performed in or separate pieces fed and delivered by suitable means to the machine for converting the same intoeyelets. As shown, the first set of the series E G cuts the planchet 1,Fig. 5; the second set E G draws the planchet into the cap-2,-Fig; 8; the third set partially draws and contracts the. bottom of the cap 2.into the shape 3,-Fig. 8; the fourth set shapes this contracted cap into an eyelet with'a wide flat flange, 4, Fig. 8; the fifth ,onttbe closed small end of the eyelet 5,. Fig. 8; and the-sixth set is also a cutting-punch and die, the punch having a protruding center-guide, f, at the end for .giving position to the eyelet on the punch, and this trims the wide flange to the required size and evenly all round with the body. The first two separate sets for cutting and giving the first drawn form to the planchet may be merged in one set in the manner shown in Fig; works inside the cutting-punch E and forming-die;G? is' arranged below the cuttin g-die'Gr in the same piece of metal, and the planchet is first cut from the sheet by the punch anddie E G, and immediately following the pla-nchet is carried into the lowe r part Gr of the die by the'inner' punch E and Iormed into the cap 2 in a manner well known in making eyelets. The partial draft of the cap,

with, as in making shirt-eyelets of ductile material, or two or more partial drafts may be here introduced for making long eyelets, or others of the harder and less ductile metals. In the punch and die of the fourth operation, as shown inNo. 4, Fig. 8, the cup receives the eyelet shape, consisting of aconical or tapering body, withthe edge of the cup, turned over to form afiange. To such operation there is herein supplemented a swagin'goperation upon said flange to reduce its thickness of metal to approximate that of the body or opposite small end; and this is accomplished by so constructing and arranging the mechanism which operates this punch as to exert a pressure upon the flange after it is turned, and by so doing swage the flange of metal between die sufliciently to reduce the metal of the flange to the thinness-of the body of the eyelet or nearly so, and flatten it at right angles thereto, and any excess of breadth of flangewhich is thus pro- 1 quent operation of a cutting-punch and (new sever, by a vertical cut all around, the superfious metal irom the said flan ge. By thus swag-- iug the flange of thejeyelet and. trimming it concentrically with its bod'yfafter it is formed, the

spring q, and operated ofall eyelets made separately from plan'chets'is obviated, and the eyelets will be of the. same.

thickness, will turn overequally and have the same appearance at both endswheninserted.

Besides separate pieces in the form of planohets or di'sks, I propose to use hexagonal and octagorial and other-shaped pieces, which may be cut with economyfrom sheet metal and be-with facility-wrought and transferred to be wrought into the form of .eyelets or similar articles.

The. sheet metal isfedto the cutting-punch and= ing'cylinder V beneath the tabieto feed in'one direction, and in the'oppo'site direction to return the rollers M to resume-the feeding operation'by means of :the spring,U or a suitable force., At the same time with this return of the sheet. by

It will be seen-that. the feed-rollers are placed at an 'angle with the lineofdirection inove with the carriage R, and that'the sheet is also presented and advanced'at an'angle, so that the planchets arecut-in diagonai rows across the sheet from side to side, that the center of the cutting in one rowis opposite the space between the'cutting oi the next adjoining ones, which is produced byashcrt and long tooth or division of the ratchet-wheel which has the eflect to make the tings in the sheet as close as possibleto each other, and thereby leave a very small. percentage of waste. U v 1 Having described the construction and operaf tion of the several parts of the said machine, it will be understood that, by the combination of the transferring devices with the series ofzpunches and dies operating consecutively, eyelets can bemade fromplanchets or separate piecesas by a. number of consecutive operations of a series (if instruments upon a strip of metal, with the .ade a: a... nein theapreduct, arising from the. more equal distribution of the draft or strain 'upomthe metal when used-in the form of a dishor planchet; a150,:thalt oration.- of swaging and tri mningthe flange this thick mugh pucluercd edge peculiar to the flange perfection fmmplanchets orseparate pieces, as

But these, it will ap pear, difi'er essentially from the combination herein set forth in both the number and nature of the operationsto which the planchet is subjected to convert it into the finished eyelet, and in the character of the transferring mechanism employed to transfer and present the planchet in the greater number and variety of forms produced by the several sets of dies and punches thus employed.
