In thedrawings, 20 is the frame of the machine and 21 is the main driving shaft which is journalled to rotate in a suitable bearing 22 provided in said frame. The main drivingshaft 21 has a pinion 23 fast thereon and meshing with a gear 24 which is journalled to rotate upon a shaft 25, the latter being mounted in

bearings

26 and 27 secured to said frame. The gear 24: constitutes one member of a clutch 28, another member 29 of which is rigidly fastened to the shaft 25. The two

members

24 and 29 of the clutch 28 are clutched together as one piece by suitable mechanism (not shown in the drawings, but well known to those skilled in the art). said mechanism being operated from a suitable treadle (not shown) by a lever 30 and treadle rod 81.

The work as for example, sheet material A which is to be operated upon is supported upon a work support 32 which is secured at the outer end of an arm 33 formed integral with the frame 20. Mounted in the "ork support 32 is a block 34 embodying therein. an opening 35 constituting a die, and an anvil 36. The block 34: is mounted to slide in a horizontal plane in the work support 32 and receives its movement from mechanism hereinafter to be described.

is constructed in two parts and ll) which operated by mechanism hereinafter to be describech to teed said l'lVQ' S one by one l' another raceway 46 down which they p; into a rivet carrier 4?. lhe rivet carrier --:i

are supported upon spring arms 50 and respectively and the latter are in turn, tastened to the opposite sides of a rivet car rier slide 52 by a bolt The rivet carrier slide 52 is mounted to slide in the h ad portion 54 of a swinging auxiliary tranie together with a driver slide 58 a punch slide 57 and a stripper slide all of which are adapted to be moved vertically within said head by mechanisms hereinattcr to be described all of said slides heiugg held in said head by a bearing plate 59 which i sooured to the front of said head The auxiliary frame rigidly tastened in any suitable manner to a vertical shaitt 60 which is mounted to roclin bearings (31 and 62 formed integral with the frame 20. A rocking movement is inu iarted to the auxiliary frame and shaft by a lever 63 pivoted 64; to the :trame 20K one end of said lever 63 being operatively connected by a link 65 with said frame while the other end of said lever 63 has a cam roll (36 journaled thereon, said cam roll pr: jeetiugg into a groove 67 formed in the peripher Y of a cam 68 fast to the shaft 25.

Before the rivets 38 can be inserted in the sheet material A it is first necessary to punch holes through said u'iaterial. This is accomplished by mechanism as tollows:-- Rigidly secured at the lower end of the punch slide 57 is a punch holder 69 in which a punch 70 is secured by a screw 71 and said punch 70 co-operates with the die 85 of the block 34: during; the downward movement of said punch slide and punches a hole through the material A in the usual well known manner. A vertical recipro catory movement is imparted to the punch slide 57 by a lever '72 pivoted at 73 upon the frame 20 and the trout extremity 74: 0t

said lever 72 cylindrical in term and problocl: 75 which is mount- 76 rigidly secured to the jects into a sliding ed in a member upper extremity of the punch slide 3?v rear extremity ot the lever is 77 being provided with turcations 73 and T9 between which a cam roll 80 is rotatably mounted. Another cam roll 81 is mounted in alignment with the cam roll. 80 upon the opposite side of the furcation 7.9 from that upon which the cam roll 80 is mounted, and

said cam roll 81 "no cots into a roove 82 L i) d cam 8a, lhe cam slide.

The driver slide 56 has a driver 86 rigidly tastcned thereto a siutable manner and projecting, downwardly from the lower end thercot and lid driver slide has a vertical reciprocatory n'iotion imparted thereto by a lever 87 pivoted at 88 upon the frame 20 and the front extremity 89 of said lever 87 is cylindrical in form and projects into a sliding block 90 which is; mounted in a mem ber 9t rigidly secured to the upper extren'lity of said driver slide The rear extremity of the lever 87 is torlied at 92 being pro" vided with 'lurcations 9;} and. 9% between which a cam rol 9;? is rotatably mounted. Another cam roll 96 is mounted in alignli'lGlltT'Wli'l} the cam roll 95 upon the opposite side of the :i'urcation til from that upon which the cam roll 95 is mounted, and said cam roll 96 projects into a groove 9'? termed in the de of the cam 68 hereinbetore men-- tioncd. The cam roll 95 bears against the periphery 98 ot an auz-iiliary 1m 95?, said periphery of said last'named cam being adjacentto and aligning with the inner wall 100 of the cam groove 97. T he cam groove 5)? ot the cam 68 and the auxiliary cam 99 form, in etfect, a single cam, and provide a construction which -::o-opei.'aes with the structure of the ad acent end of the lever 87 in forming; a strong and powerful during' n'ieans for the driver slide 5c.

After a hole has been punched in t l 1e mapunch has been wit .ilrawn froin the mauiah the frame is rocked to more the punch out of ali. mnent with said hole and the driver 8t into alignment therewith, and at the aame time the bloclc 34.: moved to position the a vil. 3t; beneath the hole in said material in order that a rivet may he clinched in the material atter said rivet has been driven through the hole. The block 3st is therefore moved to iosition the an il 3f; as above outlined by mechanism as tollowsz-lli Jlly fastened in any suitable manner to the vertical rock shaft (30 an arm 101. and the latter is operatively connected by a linlt 1013 with a bell crank lever 103 pivotally mounted at 10a upon the Frame 20. The bell crank lever 103 is, in turn, connected by an adjustable connecting rod 105 with a bracket- 106 rigidly tastened to a slide 10'? which is mounted to slide in a vetrical plane between ways 108 terial A. and

the slide 7 esson;

provided in the arm 33 of the frame 20., as illustrated in Fig. 1. The block is adjustahly mounted in :any suitable manner atthe front end of the slide 107. The slide 107 is securely held in the arm 33 by a plate 109 which is detachabl' secured to the upper surface oi 'd arm. it will, therefor-e be seen that with each mocking movement imparted to the fran'ie "by the cam (58 do move the driver 86 into position above the hole that has been punched in the sheet niateria l, the block 34 will at the i-iaine time be moved to position the anvil '36 in alignment with said driver.

A column of rivets 38 in the raceway all are fed one by one to the race-Way 16 by the slide in a 1110. 11118]. well known to those skilled in the art, said slide heing driven hy a yielding mechanism so as to avoid any injury to the rivetin case it should become jammed during uassage atrom one or said raceways to the other.

Referring particular-r1 to Figs. (5 and Y, a member is rigidly secured in any suitable manner to the head portion 5+1 01 the swinging l-rame and said member 110 has a pin 111 prof]ectingtherefrom which engages an arm 1.12 of a hell crank lever 113 pivoted at 11a to the anus 20. vAnother arm 115 ol' the hell crank lever 113 has a pin 116 projecting therefrom which engages a shoulder 117 formed upon the slide 45. A spring 118 =c -)nnects the pin 116 with a pin 1 19 projecting from the trame 20 and said spring, therefore, always acts to hold the arm 112 of the 'hell crank lever 1'18 against the pin 111. Another spring 120 is con neeted at one end thereof to the pin 116, while the opposite end of said-spring is connected to 'a pin 121 mounted in one end of This last mentionedspring elivays acts to hold the slide in yielding engagement with the pin 116. l 1th each rocking movement imparted to the .lra'me 44, as the head portion 54-. of said frame moves in the direction of the Iii l'lOW Z Fig. 7, the pin 111 will engage the :arm of the hell crank lever lever and causing slide toward the lett in 6 airways holding the shouldered portion 11 of said slide againstthe pin 116. This :inovement oi the slide l5 carries the lowermost rivet 38 in the column of rivets in the raceway let into'alignmen't with the raceway l6 down which said rive t passes into the rivet carrier -17. During the movement elf the frame in a reverse direction to that indicated by 'the arrow-b in Fig. 7 the spring 1 18 will act to rock the loe'l'l crank lever 1 13 in an opposite direction mentioned holding the arm 111:2 thereof against the pin 111 antl' causi ng the pin 116 to torce the slide 45 toward the right in Fig. 6 and pack to its initial position.

This ancelui-nisin hereinafter to he referred to .as the stripping mechanism is as lilo'llovv. .Reierring particularly to Figs. .9, and 111. the tr-inner slide 58 is provided at its lower end with a laterallv projecting extension 130 upon the under side of which is located a tr-usto-conihearing plate 59.

thereof tor a portion of said cal work engaging portion 131. A hole 132 extends through the extension 130 and conical portion thereof and the punch 70 reciprocates through this hole. The slide 58 has a tooth 133 formed thereon which is engaged by a pawl 134C pivoted at. 135 to the frame and a spring; 136 acts to normally :torce the lower end of said pawl against an edge of the stri iipor slide and into engagement with tooth 133 when said slide is located in its lowermost position. A. pin 137 projects from the side of the pawl ltl-l and said pin is engaged by a cam l ll'w tast to the punch slide 57 during the upward movement of the latter, there i discneagingg: said pawl lrom laid tooth. and thercaiter allowine' the stripper slide 58 to he moved upwardly and out of engagement with the work by mechanism as tollow.s:

Referring: particularly to Fig. 9, the stripper slide 58 is provided with a slot 139 extendina longitudinally thereof for a portion of its length. and said slide is also provided with a hole 140 extending from the upper extron'iity thereof and communicating" with. the slot 139. Grooves 14.1 are also provided in the opposite sides of the slot; 139, said grooves being extensions of the hole 1&0. A pin 142 projects t'rom the head into the slot 139 and a cylindrical member 1 13 is slidahly mounted in said slot 139 and grooves l-tl and rests upon said pin 142 and said cylindrical member constitutes aseat against which the. lower end of a spring 14% located within the hole 1-1-0 may rest. the upper end of said spring contacting with the lower e:-; tremity of an adjusting screw 145.

The sprint; 14-4 normally holds the upper surface of the extension 130 of the stripper slide 58 in engagement with the under surtare of the punch holder 69. hen, however, the punch slide 57 is forced downwardly, it will carry with it the stripper slid-c 58, carrying the latter from the position illustrated in Fig. 9 to that illustrated in Fig. 10. at which time the pawl 134 will drop over the tooth 133 but will be located a short distance thereabove. During the downward movement of the stripper slide 58, the spring 144 s compressech and as soon. as the punch slid-e 57 starts to move upwardly, the spring 144 will cause the stripper slide to move upwardlv until the tooth 133 engages the lower end of the pawl 134:, as illustrated in Fig. 11. The frusto-conical lower portion of the stripper slide 58 will. now remain in engagerwnt with the upper surface of the material A during: the interval that the punch 70 is being; witlulrawn from said work and until the cam 138 engages the pin 137 when said pawl. will be disengaged from said tooth allowing the spring 144- to again force the stripper slide 58 upwardly to its initial position.

The general operation of the mechanism ;g'cl'lici', are placed upon the work support 32 and that that portion oi": the punching strippingl rivet carrying; and driving instrumen- Hilllith' illustrated in Fig. 1 are positioned l'lltlllVQlV to the work support 32 and the material A located thereon as illustrated in said Fin. l2: the operator starts the machine by operating" the rlutch 28 in the usual well known manner. The punch slide 57 will then immediately start to descend carrying with it the stri 'ipcr slide 58 and said slides will continue. to descend in unison until the lower eiltren'iity oi the work engaging port on 131 oi said stripper slide contacts with the work A and the punch 70 has been .driven through said work. The punch slide 5'7 will then tart to rise. leaving; the stripper n engagement with the work until the punch 0 has heen removed from said work, as illustrated in Fig. ll. a tter which the stripmechanism will also move upwardly to its initial. position.

The swinging ilranie is then rocked to align the driver 86 with the hole that has been punched in the work, and at the same time the block 34 is moved to align the anvil 36 with said hole in said work, the latter remainino; stationary upon the work support. The driver slide 56 now descends, carrying with it the driver 86 and the latter engages the rivet which has previously been fed into position within the rivet carrier 4'7. and as said driver forces said rivet downwardly through the rivet carrier 47, as illustrated in Fig. 14-. the rivet carrier slide 52 will also move downwardly in the head of the swinging frame 55 and upon the driver slide 56 until the rivet carrier 4-.7 assumes the position illustrated in Fig. 15. The rivet 38 upon being; forced through the o 'ienine' termed in the work will contact with the anvil 3t) and will he clinched against the under side of the work. as illust ated in Fig. 15. The driver slide 56 will then ascend carrying with it the rivet carrier slide 52 and rivet carrier 47 and as said slides return to their normal positions with in the head 54 ot the SNilifl'illf; frame the latter will he rocked to its initial position as illustrated in Fig. 7. at which. time the pin 111 will engage and rock the bell crank lever 113. causing the separator slide 45 to teed the lowermost rivet in the column of rivets in the raceway 44. into alignment with the raceway 46 and allowing said rivet to slide into position within the rivet carrier. The work A is then ted manually upon the work support 32 and corrcctlv positioned to rece ve another rivet and the sequence of operations previously mentioned. is then repeated until all of the rivets necessary to secure the layers of said material together lit) . have been inserted therethrough and clinched therein.

In certain classes of work it may be necessary to employ a device tor clamping the work to the worl: support 32, and this may mecl'ianism such as is illustrated in l 18 in which a suitable clamping member 146 illustrated as being pivotally mounted at ll? upon a bracket 1498 located at the rear of the'worl'r support 32, and said clamping member l i-.6 is held in yielding engagement with said work support, or the work located upon said work support, by a suitable spring 1:49.

When the clamping device is em iloyed, the work is placed upon the work support 32 beneath the clamping member 1416 and the latter holds said work firmly worl: support during the various operatlons hereinbetore set forth.
