The correspon(ling parts of cam 39 being correspond6 ingly design,,tted 6n the drawings the operation thereof on the lower punch and set @will be re,,i.dily undorsto6d ' For effecting tl-ie e-ndwise movemeiit of the. slide block 10 to moire the punches and sets io. 1,,iterally as described, t ltteral face c,,im 44 is fixed, on the shaft 5. This cam is enga(,e(i by a roller 45 on the outer end of lever 46 iulerumed ,it 4T to the frame work with its 'Mner end engaged with a link 48, the i5 other eild of which has pivotal eiip-agement ,it 49 with the blocli: 10. The eno-agement of lever@ 46 with the link 4S is I)y rneaus of a pin 50 eiio-,aged i the link 48 and adal:)ted n to be adj Li@t-atly claml)ed in (tny part of aii 20 el6ngated slo ' t 51 of the lever by means of a flange 52 thereon @ and, a clamp nut 53 threaded thereto. The purpose of adjusting tho point of en agemeht of this link end 9 along the lever 46 is to vary the exteiit of 25 movement of the block 10 and hence the spacing of the eyelets as eitected by the lateral.ii,i6vement 6f the . plinches while engaged in the materl,,tl. It will be understood that the f ormt:tioii of lateral cam 44 is s Lich as to @o move the p-Linches 1,,iterall@ for feeding while they ,ire under the action of the portions 38e ,,i,nd 39c of the respective peripher,.tl cams u n ,,Yi(:l to perniit return o2- the p nehes to i itie@l position while the portioiis 38a and 39- 35 of the peripheral, c,,tms are active. This later@.tl ret-Lirn 6f the pliriches to initial positioii.is effected by a stou,t coil spring 54 engage 1-1 Nvith a. pin 55 6n the block 10 Itt o-ne end and witli ,t pii-i 56 on the frame work at 40 its other end. @ It ivill be u-nderstood thtt is the p-Linch aiid set mechanisms ,tre tliiis moved later,.tlly they slide along the face's 35 of the levcrs 30, 313, respectively, Nvhich ,qre iiiade ividc@ enoulh t6 i3ermit this lateral 45 rhovement. . The Lipl)er tncl lower eyelet raceways 42 Itre Similar blit oppositely disposed so as to present the eyelets@properly to the material ,,Lt tbe-opposite, sides'of the slipport. These 5o rqoeways are ftd,,tpted to cleliver eyelets I of widely vtrying sizes aiid hold them properly alined to be catiaht bv the punches and for this pil-rpose I ]@lrovid" e ftn @extension to the main racew(,ty portions 58 consisting in 55 1,,tteral portions 59, 60 pivoted to the: main portions at 61 @,tnd ,tdapted to be simultaneoilsl-v adilistecl toivard 6r from@ e,,tch other @y a s6reiv 62 which has its two end portions opposit6ly threadod tnd engoo-ed ivith nuts 60 63 on the respective lateral portions of the raceway. Thus by merely tlirning this screnv the delivery p6rtion 6f the raceway be acljusted to any wi@dth required. M@ley T tacoways 42 are 6arried in the slilde 6 5 block 10 @ as best shown -in li'.ig. 4, being 14,932 gltided for endwise slidino, rnovement thereC3 iii aiid held in place by a retaining plate 64. These racew,,tys and a hopper 65 whicli slipplies the eyelets thereto ,tre moved so as to bring the foremost eyelets into aliiiement 70 with the punches ht the proper interv,,Ils and then move back out of the way for the setting operation, and for this purpose I sliow a 66 fixed on the sha-@'t 5 and enoayina a depeiiding abutment med@ber 6T 75 t, t, tD 0ii the racew,-Lys. As a means@for starting the eyelets in the respective raceways so that they will face in opposite directions as required I i:)rovide a plate 68 intermediate the heigl@t of the hopper -with a groove 69 80 therein and leadin- to the tipper raceway, this groove beiiig a -wiclth to permit the shtnks of the eyelets to drop thereiiito Ind the eyelets rest 6ii their fl@nges to slide out along the raceway. The lower race- 85 way leads out from the bottom of the hopper Nyitl-i spaced apart guides 70 so as to permit the upstanding shanks to slide therealon(r as they rest on their flanges. It Nvill be unclerstood that the mass of eyelef@s in the 0 hopper is ao-,itated by the reciprocating later,,tl movem@nt imp,,trtect from the slide block 10 to the raceways Nvhich siipport the liopper, and this ,Igltation is promoted by the operttion of the c,,trn 66 -vvhich reciprocates the raceways endwise and of course the hopper along with them. In gddition to this a suitable brush device (pot shown) may be employe d in the hopper to be moved for stirring Lip the eyel(@ts to start them in their ioo respecti ve raceways. lvhil @e the members 30, 33 h,,tve been referred to as levers ()r h,@tmmer@, for convenience in construction and assernblage each of these mernbers is shown as formed of sepa- lo,,5 rate lever arms spaced apart latertlly and fixed to ,t shaft; thlis what has beei-i c,,tlled the hammer lever 30 is mtde up of the ,trms 30a ob fixed at the respective ends of . a sh 't@f 30c journaled at the fulcrum poii-it 31. 110 The oper,,ttion of the described mechanism will be understood from the foregoitl(, description ,tnd needs to be only briefly summatized: The two pieces of m,@tteri,,il being supplied to the opposite sides of the 1'5 m,,tteritl supp6rt 12 underneath the presser p ates 14, t e, operatioii o the m,,ichine caiises the two punches to be pressed forward simult,,ineously while held positively projected from the sets, the initial part of their 120 inovement being relatively slow. IT-1 this movement e,,tch of the punches tikes up the foremost eyelet from its raceway and as the raceways move bacli: out of the w,,ty aiaOL the punches continue to move forward, the eye- 125 lets slip b,,.teli: on the punchos as the punches are pressed throuuh the materi,,tl against the punch block s@irfaces of the support 12, the flange ends of the oppositely facing eyelets on the two punches coming up against 130

the respective sets. Then th6 unches being sli,-htly inoved bacli: so as t@ be rellevecl f-roni the ptinch- block -surfaces, the lateral into action @ to m ve th cam 44 comes 0 e punel-ies and sets laterally the dist,,tnce the eyelets are to be spaced, i. a., from some vari,ible initial position to t positi6n opposite the cleiicliing surfaces 43, this va-ri,,tble initial position b6ing determined by the ld10 justment of pin 50 -in@ the, slot 51. The Con'tbur-and arran ement of the elonoated slot o@ .51 is such thpt-it compensates fo@ the varying in the positioins of the punch @and set m6chanisms. relative to the clenchin(y surtrl 15 faces-.43 that would otherwi,,,,e occur by ad'n tid sl t, so tlilt j ustment; of, the pin 50- i 7 s, 0 notwithstanding such aditistment the punch and: set mechanisn-is al@vays@ come to rest in OI)erative positi6n opposite the -clenching 20 stitfaces 43. This later,,tl shiftin- of tli@ punch and.- set'mechanisr@s bri,ngs the sets opposite the recesses 57 in the lever faces 35. Theretipon a further movement of the levers 30 33 under the iction of the poy-- 25 tions 181, 391 of thei.r respective cams moves the sbts f arthei @f6rward to effect the clenchingo, Of the eyelets, the punches is this occurs receding ivithin the sets, since their rear ends may move@back into the recesses 30 57 whic are too small to receive the set sleeves 21. Then the punch and set mech,,t-@ nisms being permitted to move out of the material and back of the raceways by the lower 13ortio-us of the c,,ims @ and beii-ig re35 turned to initial @ lateral position by @ the spridg 54 the cycle of @ 6peration is com pleted. it will be noted that the sets 23 are conveniently a djustable in the set sleeves by 40 their threaded enga ement therewith to be ol locked by tl-ie nuts 24 so that th@y may be set accurately. according to th,e reqtiirement's of the particular work in hand ,tnd the normlltl forward projection of the ptinches as 45 yieldiiioly held for-ward can also b6 cletermined bv adiustmeiit of the n-Lit 28.
