1,688,436, to which reference may be had for a full description-thereof. The machine is provided witha work support or horn mounted for rotary movement about a short shaft 12 which may be latched in either, one oftwo positionsrelatively to the operating instrumentalities of the machine by mechanism more fully described here inafter. The machine'is also provided with a'i'head 26. vertically movablelto permit the .worktobe placedupon and removed from (illthe work support20 when the machine is at rest and moved vertically .to a much ,less extent during each; cycle of operation of the machinert'o relieve the pressure upon the work as, the work is fed.

Lever 120: controls the passage of the fastenings from hopper 56 to the nail tube 100 whichleads'to the cylindricaldriver passage or throat opening 142 of nozzle28.'

Turning now to the novel mechanism of the present invention, the head 26 of the machine has attached thereto a bracket 202 -extending along its right-hanctside and and having formed in it a guideway 203.

extending from front to rearof the machine.

In thisguideway is mounted a slide 204" hav ng a curved, forwardly pro ect1ng portlon 205 formed with an arcuate slot 206 the.

center of curvature of which, indicated in F 1g. 2 at 207, hes 1n a vertlcal plane pass-- ing through the axis of drlver 208 and. en

tending rearwardly. Located in slot 206 is i a pair of vertical studs 209', each carrying a c'uate movementabout center 207.v The lowor plate 212 is extended forwardly and has pivotally connected to it by a horizontal pivot 213 a feed member comprising a plate or finger 214 pressed downwardiy toward the work by a flat spring 215." Atrits forward end feed finger 214 isformed with a pair of vertical faces 216,217. Face 216,

which extends forwardlyand rearwardly of t thefinachine, is, before the-starting of the feeding. movement, at the right of the path of the driver 208 carried by driver carrier 40 g V and face 217 extends transversely of the tical rod-30flwhich extends through a bear-- machine at the rear of this path, During the operation of the machine, finger 214 is given an oscillating movement either to the right and left or'forwardly andrearwardly according to the desired'direc'tion offeed of the WVQli(,-t1l(l as finger 214 is thus moved,

feed the workpiece.

to slide 204 and arranged alternatively to lock shown in Fig. 2. Pivoted at to a pair of ears formed on plates 211,212 is a link 224" pivoted 'alsoto an arm 225 slidably mounted upon a vertical rod 226. A lug 227 formed'on bracket 202 supports arm 225. Fixed torod 226 somewhat below arm 225 is an arm 228 having secured to its extremity a pin 229 passing upwardly through an opening'in arm 225 so thatarm 225 will be rocked by rod 226 but will not be affected by vertical movement of rod 226. Rod 226 carries also an arm 230 provided with a cam roll 231 urged toward engagement with a surface cam track formed upon a cam member 288 byaspring 290. To vary'the extent of the rocking movement of rod 226 and, accordingly to vary the extent of feed, an adjusting screw 232 is provided carried bya stationary part of the machine frame and "arranged to engage a lug carried by arm 230 to limit the movement of cam roll 231 in the direction of cam 288.

"The mechanism which has just been de-- scribed is operative to reciprocate plates, 211

and 212 and the feed finger 214'carriedthereby either in a forwardly and rearwardly di rection if slide 204 is free to move forwardly and rearwardly and is latched by latch lever 218 to plates 211 and 212 or transversely if slide 204 is locked against movement by latch lever 218 but is released from plates 211 and 212. Under the circumstances last mentioned, plates 211 and 212 are given an arcuate movement about center 207 and, accordingly, face 216 of feed member 214 is moved transversely of the machine in a path which, on account of its comparatively large radius and short arc, sufficiently approximates a straight line. In the illustrated machine the proportions of the parts are such that if no change made in the arc of rocking inovement of rod 226,,v the extent of the transverse feeding movement giten to finger 214 will be somewhat greater than that of the forwardmovement since is ordinarily desired to; space nails inserted across the rear end of a halfsole somewhat closer than inserted around the periphery of the sole of a shoe.

An edge gage 254 is illustrated in Fig. 1

arranged to guide the work fed transversely of the machine. Edge, gage 234 is positioned beneath feed finger 214 and is formed at the forward end of a rearwardly extending bar 285 pivoted at its rear end by a vertical pivot 236 carried by a block 237 attached by a screw-'and-sl'ot connection 238 to bracket 202. A springplii-nger 240carried' by bracket 202 is arranged to enter a shallow OPQIIIIIQ formed in bar 235 so as to latch the latter in position to-hold gage member 234 in 0perat-ive position while at the same time permitting the gage member to be swung rear wardly out of the way when it is desired to insert fastenings transverselyof the worker when. for any other reason, the gage member either is unnecessary or in the way.

During the operation of the machine,'noz-' zle '28 is moved downwardly'into engage ment w'iththeupper face of feed finger 214 to clamp the work against work support 20. Driver 208 then drives a fastening into the work, leaving the fastening projecting a distance substantially equal to the thickness of feed-finger 214. The work piece is then transversely orforwardly o'f-tlie machine according to the position of latchlever 218, In order 'to complete the driving of the fastenings, the throat member or nozzle 28 is provided with a pair of vertical faces 243, 244

(Fi '4) formed at right angles to eachv other and extending toward the leftand. to-

ward the front of the machine respectively. These faces. have formed in them vertical grooves 245, 246, which receive tongues 1247, 248 formed upon a driver block 249 of a.

shape conforming to that of nozzle 28and thus guided for vertical, sliding move-mentm Fixed to driver block 249 is a bar 250, the upper end of which is hookeshaped, as shown in, Fig. 3, to engage a co-operat1ng hook member 251 carried by the forward end of arm 120. Resting on the upper face of driver block 249 is the lower end ofa rod 253 guidedfor vertical movement in an opening formedin' the throat member 28 and carried positively fed by the engagement of finger 214 with the partly driven fastening either iii) by and vertically reciprocated with the driv er carrier'40 which carries also driver 208.1

Thus at thesame time that driver 208 drives a fastening part way into the] work, driver, block 249 completes the driving of the 1ndividual fastening, the insertion of which was started'fin the preceding cycle; The areaand shape of the lower end of driver block 249-are such as to do this-whether the work is fed transversely or forwardly and whatever the length of the feeding move-- ment "with n the limits permitted by the ma-J chine.- In this connection it may be noted that driver block 249 extends generally forwardly and to the left of the path of driver 208 while'fced finger 214 extends rea-rwardly andin the right so that the'two do not interfere withfeach otherq Moveovefldriver, block 249 is moved upwardly in 'tlie'oper tion of the machine before finger 214 makes iao ' a block 255 pivot-ally secured at 256 to a brack its 'feeding inovement andfis not moved downwardly until after finger. 214 has been retracted. r

Since the tinal driving, and, therefore, the

clenching of the fastenings, is effected either 'to 'tae left or n front of the driver bar, 7 1tis desirable to alterthe position of the horn tip on which is formed a clenching surface, illustrated as a clenchingcavity 258. Ac- QOZCtlHgly, horn shaft .12 is carried by a et 5'? securedto the frame of the machine. Thus clenching cavity 258 may be swung laterally from a positionat theleft of the path of driver 208 to a-position in front of lhe path .of that driver. To lock the horn shaft in, either one of; these two operative positions, block, 255 is provided with a spring plunger 260' carried by a handle-259, plunger 260 being arranged to engage either one of two V-shaped recesses 261, 262 formed ing-inserting means in bracket 25?. Between the recesses .261.

262 is a hardened block 263 :the .facesof which formjone side of each recess and over which the Dlun er sna swhen the horn block 255 is adjusted. At its end remote from bracket 25? plunger 260qis provided with a ring 264 by whichjitinaybe withdrawn so as to allow the-hornto be swung about pivot 256 into an inoperative posit-ion remote from nozzle 28. i
