The mechanismfor actuating carriage 105 involves an arm'107? that is fixed by set bolts 108, 108 to the end of a longitudinally movable shaft- 109 carried in journals 110 110 attached to the side surface of table 1. The end 111 of-arrn 107 plays in an open recess 112 formed in the .side'of carriage 105, whereby to strike the opposite surfaces 113, 114st the ends of recess112 to give the carriage a rather quick motion in either direction which isbest-adapted to feeding wire forward and thereafter sliding therealong'to gain anew position on'wire'33 preparatory'to again feeding it forward.

The means'for actuating shaft109 embodies anarm 115 having a socket 116 that is fixed to shaft109 by set bolts 117. The outer or free end of arm 115 is pivoted to aconnecting rod 118 by headedshaft 119. A headed shaft 120 extends laterally, from the opposite end I of rod 118, and. engages. a straight open guide groove 121 formed by raised portions 122, 122 on'disk 123.

Bolts 131 project elongated slots 1330f plate 130 into threaded apertures in table 1; A grooved pulley-134 is keyed at one end to turn with the shaft 127.

A guidepulley135is slidinglymountedand adapted to rotate at the opposite end'of'bearing 128 on said 'shaft127. Yoke136 having bifurcated ends 137, 137 resting in groove 140 of pulley 135 is adapted to move pulleyl35 longitudinally for apurpose to. be hereafter described. The cndjaof yoke 136 is bolted to rock block 142 that is pivoted at 143 to adj ust able-plate 130. Bar 144 ispivoted by bolt 145 to, block 142'in a counter sunk recess on the side opposite to thaton which yoke 136' is bolted. Along side of bar:144 is disposed a second bar 146 that isrigidly bolted at 147 ,1

147 to rock block 142. 7 Bar 144 has a screw threaded aperture for the receptionof a headed bolt 148 proj ecting through aloose'apert'ure made-in the adjacent side of bar 144. Headed bolt 148 isadapted to increase or decrease the angle between bars 144 and 146, whereby to hold bar 144 in given predetermined relation to bar 146 in orderto control'the extent of the rocking motion of yoke 136. The end of.

Guide pulley 135 has formed integraltherei with conical or wedging part 155. Cam surface 152 gradually inclines outwardly and.

then. has a rather abrupt shoulder at 154, whereby conical shapedroller 150 will move first outwardly to rock yoke 136 inwardly to move wedging part 155 towards the adjacent as well as block 142, whereby saidparts, especiallywedge 155 can be moved more or ends of knife carryingjaws 161' and thereby forceknives165-intocutting position and then be withdrawnfrom saidcuttingposition when wedging part 155 is'withdrawn by the reverse actiontof yoke 136under influence of spring 156, as roller 150 moves past shoulder 154.

whereby saidknives 165 will effect the cutting of annular grooves 160 inw-ire'33a Jaws 161 are revolved in a 'planetary-manner about wire 33 by the connection of grooved pulley 134 by means of a -belt with a power pulley,

Furthermore, one of Leo , said grooves 160wi'll aidthe wire cutting means in severing aid wire, now to be eX- plained. 1 v The means for cutting wire 33 into proper lengths for'the formation of chaplets 167 is eifectedby a plunger'knife 168 which is ac tuated forward by a rockmember 169. Rock member 169 has formed on its lower end a laterally. extending shaft 170 having a bearing in journal box 171. arm:172 isrigidly attached to'the opposite end of shaft 170. The upper or free end of arm 172 carries v roller 173 which is pivoted on a shaft-fixed thereto. I Roller 17 3 is -in contact with the outer surface of roller '174 having a raised nub 175across said-surface. Roller 174 is fixed to turn with shaft 98. Each'time nub 175 comes in contact with roller 173it-will V an aperture 177 throughvwhich wire 33 pass: es. Said nner end of k111fe168 is'contiguous with a cutting edge 178 of die block 32 and will move therepast into a recess 17 9 formed for the purpose, in order to cut'wire 33 into proper lengths. A coiled spring 180) fasing 39 will retract knife 168 after its impulse forward.

Shaft98 is carried in bearings 158 and 183',

and having the usual oil cups 184, 184.

Metal tape 55 and vwire'33 When the machine is started, metallic tape 55 will be fed intermittingly towards die 32 by the forward motion of carriage 75." As tape 55 arrives opposite die 32fandwithiits free end resting adjacent theside of bracket will be drawn off fromreels, not shown. 7

34, wire 33 will be projected through an aper ture made in tape 55, which aperture "was made by the preceding stroke of punch 54.

tape 55. Simultaneous with this operation, member 31 will be. forced forward by link 27 to hold wire 33 rigidly, while plunger member, 43 carrying'die 60 moves forward.

Die 60 will strike theend, of wire 33 at the location of hole 61 therein and upset theend of wire 33 on the outerface of metallic tape 55, whereas, holding member 31 will cause'the.

force of the blow of die 60 to also upset wire.

33 on the inner or oppositeside of tape 55, thereby riveting the free or cut end of wire 33, firmly to metallic tape 55. The end of 7 wire 33 will'be roughened'due to roughened surface of hole 61 in die 60. Also plunger knife 168 will be actuated forward past cutting edge 178 to out or shear wire 33 at the proper-lengths, while said wire is being heldby member 31' and its end riveted to tape 5'5.

At the same time this riveting processor:-

curs, knife 'blade57 also carried byplunger operating parts.

- While tape 55 is being cut and punched by blades 57 and 58 and punch' 54l respectively, 7 carriage? 5 will'be moved. outward by arm 91 connected to shaft 98 by eccentric strap 96 turning on eccentric 97 whereby the cam head 81 of lever 80 will slip'past'tape 55 in order to secure a new. hold thereon preparatory to again feeding said tape 55 forward. During this retrogression of carriage 75, tape 55 will be held against the surface of die 32by tape holding plunger 70. Just before carriage 7 5- reaches its outermost position, the lost motion due to the interposition of spring 92 and collar 94 on said arm 91,.will. have been taken up, whereby arm 91 will give a direct quick outward push to carriage 75; This motion of-carriage75 will cause cam head 81 of lever 80 to cooperate sufliciently v with the surface of bracket 7 9, whereby carriage 75 a will draw tape, 55 outward therewith, in order to clear its cut end from interferring with the contiguous edge of the part of tape 55 that is left to make a chapletrwhile said chaplet drops down out of the way for'the formation of its successor. Duringthi's motion I of withdrawing tape55, tape holding plunger 70 will have been retracted by spring 72 and not again pushed forward by block 68, as actuated by roller 67 in contact with roller 65 having nub'66, until tape 55 has been fed again forward to cutting and punching position. During this cutting, punching and riveting operation, wire holding member 31 has been urged forward to holding position by link 27 as actuated by movable member 16.

Also, during this interval plunger knife 168 has been moved forward by rock member 169 to cut wire 33. Immediatelyafter the aforesaid operations of cutting and punching tape 55, and of riveting the cut end of wire 33 grooves 160 will aid member 168 insevering the wire leaving only two grooves in the shank of finished chaplet 16 Having thus describedmy invention,
