Referring to Fig. 1 of the drawings, the numeral 2 indicates a column upon which is mounted for vertical adjustment a head frame 57in which is journaled a shaft 6 carrying-a driving pulley 7, the shaft 6 having thereon various cams from wh ch the operating movements of the machine are derived. A gripperIIO given the usual closing, updraw and overdraw movements by mechanism similar to that shown in the prior patent before referred to.

The shoe is positioned laterally by one or the other of two edge gages 11, 12 and is positioned vertically by a bottom rest 13. A reciprocating wiper 14 is provided to wipe the tensioned upper into lasted position upon the shoe bottom and a tack is fed in each cycle of the machine from one or the other of two raceways 16, 17, to a pocket in the wiper 14 by which it is carried into position to be driven by a driver 18. The wiper 14 is mounted on a. horizontally reciprocating slide 20, directly actuated by a cam on the shaft 6 by the following construction.

' An irregularly shaped bracket member 22 (Figs. 1, 2 and'3) is secured to the slide by

cap screws

24, 26 which pass through slots in the bracket 22 and are threaded into the slide 20. The bracket is preferably provided with a rib 28 engagingagroovein the slide to hold the slide and bracket in correct relative position vertically. By loosening the

cap screws

24,26 the bracket may be adjusted horizontally.relatively to the slide, and, for the purpose of effecting such adjustment conveniently and accurately, a screw 30 having a capstan head 31 is threaded into the bracket 22 with its head engaging a notch 32 formed in the slide 20. The screw 30 is held in adjusted position by a set screw 33.

An arm 34 of the bracket carries a tapered cam roll 36 which engages'a suitable cam path 37 formed. in the edge of a cam on the shaft 6. The cam path 37 is designed to effect to and fro movements of the slide 20 and wiper 14 from a rearward position in which a tack is fed from one of the raceways16, 17, to a tack pocket in the wiper, to a forward position towipe the upper over the The cam 37 acts directly, through the bracket 22, upon the slide with out the intervention of a lever as in prior constructions, and by the adjustment above described the rearward position of the wiper may be accurately adjusted to secure proper aline'ment between the tack pocket and the tack passage of the separator block 38. To counteract side thrust of the slide 20 due to the taper of the roll 36, sliding contact is provided between the slide 20 and a plate 39 icld by cap screws 41 to a block 43 secured at 45 to a bracket 47 of the head frame 5. The holes in the plate 39, through which the screws 41 extend, are sufliciently elongated lateially ot' the slide 20 to allow the plate to be pressed against the slide. before the screws areset up, so that the plate will support the slide 20 as it moves back and forth in contact therewith.

The driver 18 is connectedto a driver bar 40 arranged to slide in a driver bar carrier 42. The carrier journaled for swinging movement on trunnions 44 one of which is shown in Fig. 2, thejournals being formed in a bracket 46 secured at 47 to the frame 5 of the machine head. This construction provides a long and rigid hearing for the driver bar carrier so that it will withstand, during long use, the continual battering of the driver blows. The slide 20 is provided with a capstan headed screw 48 which, as the i slide moves forward, engages the driver bar carrier 42 and swings it on its trunnions 44, the screw being adjusted so that when the slide has reached its forward position over the shoe bottom the driver 18 is at the proper position and angle to alinewith the tack pocket in the wiper 14 and when released driverbar carrier 42 is also made adjustable as shown in Fi 2 and 4. A rod 51 passes loosely through an ear 53 on the carrier 42 and is threaded into the bracket 46 where it'is maintained in adjusted position by a set screw 55. On the rod 51 is a fixed collar 57 against which the ear 53 is held by a spring 59 on the rod between the ear 53 and nuts 61 on the forward end. of the rod which is slotted to receive a screw driver. By loosening the set screw 55 and turning the rod 51 the rearward position of the carrier about its pivot 44 may be adjusted and its position with respect to a separator block 38 determined. The driver bar is raised by a cam 49 on the shaft 6 (Fig. 1) and is iinpelled downwardly by a torsion bar acting on an a rm 52 between which and the driver bar is a connecting strut 54. It will be noted in liigs. 1 and 10 that the cam 49 engages a projection 56 on the driver bar 40 upon which it operates to raise the bar against the driver spring 50. and that the driver bar is provided with a like projection 56 on its front side. It is hence possible, when one of the projections 56 has become worn, to

lit)

reverse the position 01 the driver bar in its carrier so as to present the other projection 56 in operative relation to the cam.

In order that the tacks may at times be left upstanding from the work, as in lasting the sides of welt shoes, so that they may be conveniently pulled out, and at times completely driven as in McKay work and in the heel-seat lasting of welt work, novel mechanism is provided for arresting the stroke of the driver. In prior constructions for this purpose driver stops were arranged to close beneath a stop collar on the driver bar. Tt is necessary to provide butter washers On the under side of the stop collar and it is difficult to prevent these from dropping down and getting in the way of the closing of the stops. The present construction avoids this and other objections to the old construction, including development of looseness and lost motion, and provides a very rigid and durable mechanism for arre ting the driver. The upper portion of the driver bar (Fig. 2) is formed as a. cylindrical reduced portion 60 which carries stop collar 61 held by nuts 62 on the portion 60. Between the collar 61 and the top of the carrier 42 is interposed a pair of

wedges

63, 6 1. The upper wedge 63 is loosely mounted for vertical movement on the reduction 60, and the lower wedge 64 is arranged to slide transversely of the machine beneath the upper wedge 63. On the rear side the wedge 64 is guided for such movement and is held from vertical movement by a rib 65 engaging a groove in the carrier 42, and at the front side the wedge has a rib 66 engaging a groove in a cap plate 67 secured to the carrier 42 by screws 68. The wedge 64 is slotted at 70 to receive the driver bar reduction and to receive a depending portion 71 of the wedge 63 by which the wedges are held in proper alinement and which rests on the carrier l2 to transmit the blow of the driver directly to the carrier when the wedge 64 is withdrawn. The wedge 64, when moved in its guide, raises or lowers the wedge 63 to vary the space between the stop collar 61 and butter washers .73 on the top of the wedge 63 and hence to vary the stroke of the driver. Tomove the wedge 64;, a ball-ended link 74 is suitably connected at one end to a projection 75 on the wedge 6st and at the other end to an arm 76 secured to a rock-shaft 78, the operating mechanism for which will be hereinafter fully described.

The link M and the arm 76 constitute a toggle which is substantially straight when the wedge 6 1 is in operative position, so that any tendency of the wedge 6 to slip out from under the wedge 63, due to the blow of the driver, will be transmitted through the straight toggle 74, 76 to the shaft- 78,

shown in Fig. 2, the drive blow is transmitted directly to the carrier 42 through the rib 71 which then rests upon it. To prevent cramping ot' the wedge 63 against the portion 60 ot' the driver bar when the wedge 6 1 is pushed under the wedge 63, an abutment 79 is provided on the carrier 42 against a vertical face of which an end of the wedge 63 bears and which takes the end thrust of the wedge 63 as the wed 'e 6 1 is moved under it.

Novel mechanism, shown in Figs. 1, 5 and 6, is provided in the present machine for giving the gripper 10 its lateral and turning movements. The upper end of the shank 80 of the lower gripper jaw is hung by a ball joint 31 to the forward end of an up draw lever 82 shaped as shown in Fig. 1 and pivoted at 84 to the machine frame. The rear end of the lever is operated by a cam 85 and spring 86 in the usual manner to impart yielding updraw movement to the gripper. The ball 81 is formed with teeth which engage corresponding teeth in a plate 87 (Fig. 5) mounted to slide in the updraw lever transversely of the machine. An end of a link 88 is adjustably connected at 90 to the plate 87 and the other end of the link has a ball joint connection with the upper end or a lever 92 tulcrumed at 94 on the machine frame. The lower end of the lever 92 is pivoted by a pin 96 to a cylindrical slide 98 which is mounted for vertical sliding movement in an enlargement 100 of a connecting rod 102, the enlargement being slotted at 101 to permit rel ative vertical movement of the connecting rod 102 and the pin 96 as the direction and position of the rod 102 changes in the operation of the mechanism. The pivot pin 96 is held in the slide 98 by a. set screw 10% threaded longitudinally of the slide 93 to engage the pin 96. The slide 98 is free to turn and the pin 96 is elongated and is loose in its hole in the lever 92 so that the necessary movements of the rod 102 relatively to the lever 92 during overdraw movement of the gripper can occur without causing the pin 96 to bind, the pin moving longitudinally in its hole in the lever.

7 As will be understood, the overdraw movetuated in a forward direction to impartoverdraw movement to the gripper by a spring actuated arm 118 which engages the rear end of the rod 112. .A carrier 120 (Fig. has hollow cylindrical portions I 121, 122' which are held by bearing caps 123,123 for transverse movement in the yoke 110. The left-hand end of the connecting rod 102 passes into the hollow portion 121 and has a ball and socket connection at 124 with the lower arm or stem 125 of a T- lever 126 pivoted at 127 to the carrier through which the shank of the gripper passes loosely and by movement of which the lateral and overdraw movements are imparted to the gripper. The

lateral arms

128, 128, or cross bar, of the T-lever are each engaged by a screw 130 threaded through a bar lever 132 which rests at its ends upon stop pins 134, 134 on the carrier 120. The bar 132 is pressed upon at its upper central portion by a plunger 136 mounted in a sleeve 140 and yieldingly depressed by a spring 142 the tension of which may be adjusted by turning the sleeve 140 which is threaded into the upper portion of the carrier 120. It will be understood that a push or pull of the rod 102 will act through the mechanism described to move the carrier 120, and hence the gripper, laterally, and that if resistance to lateral movement is offered to the gripper the T-lever 126 will be tipped on its pivot 127 and, by upward pressure on one or the other of the screws 130, will lift one end or the other of the bar lever 132 against the tension of the spring 142. Int-his manner move ment of the rod 102 will impart to the gripper, through the spring 142, yielding lateral movement in either direction. The screws 130 may be adjusted to centralize the gripper 10 with respect to the driver 18 independently of the rod 102.

When lateral and turning movements of the gripper are desired, they may be effected by imparting longitudinal movements to the rod 102 by the following mechanism: The outer end of the rod 102 has a ball 146 seated in an arm or member 148 and held in place by a ball cap 150 secured by screws 152 (Fig. 6). The member 148 has ears 154 through which are threaded cone-ended

bearing studs

156, 156, the conical ends'of which are seated in sockets in a hollow rocking sleeve 158 having a bearing 157 in the machine frame (Fig. 6). Rocking movements are given to the sleeve 158 in each cycle of the machine by means of a cam operated. lever 159 hav ing a toothed segment engaging a pinion 160 on the sleeve 158. The lever 159 is pivoted at 161 to the frame (Fig. 5) and carries a roll 163 which engages a cam path 165 in the front face of the cam block 115 on the shaft 6. In Figs. 5 and 6 the parts are shown in neutral position with the ball 146 of the rod 102 in alinement with the axis of the sleeve 158 so that rocking of the sleeve will act as a. crank to move the rod 102 iongitudinally when the sleeve 158 is rocked. To move and control the position of the member 148, a push rod 162 is mounted for longitudinal movement in the sleeve 158 through which it extends at both ends. At its front end it has a downwardly extending portion 164 ending in a hook which engages a pin 166 mounted in a downward extension of the member 148. Forward movement of the rod 162 will turn the member 148 so as to position the ball 146 above the center of oscillation of the sleeve 158 and cause lateral and turning movements to be imparted to the grioper in one direction, and movement of the rod 162 rearwardly will turn the member 148 to locate the ball 146 below the center of oscillation of the sleeve and cause the lateral and turning movements to occur in the opposite direction.

Movement of the rod 162 is effectedby rocking movement of a vertical shaft 170 having on its upper end an arm 172 in the outer end-of which is clamped a pin 174. On the pin is pivoted a block 176 which engages a slot 178 in the rod 162, the slot having an arcuate bottom to permit rocking of the rod 162 with the rocking sleeve 158. The shaft 170 is associated with the mechanism for operating the edge gages and other parts now to be described.

The thin edge 11 and the thick edge gage 12 are arranged, as shown in Figs. 1, 2 and 3, for use alternatively each to the exclusion of the other as is usual in machines of this type. The thin gage 11 is mounted to slide horizontally on a part 180 secured to the machine head at 181. As shown in Fig. 3, a link 182 is adjustably held by a bolt and slot connection 184 to the sliding gage 11 and is pivoted at its rear end to a lever 186 having a fixed fulcrum 188 between its ends. The lever 1.86 has its other end connected'by a link 190 to a pin 192 mounted on an irregularly shaped rocking member 194 to be further described. The pin 192 has a long bearing in one end of a link 196 which,

at its other end, has fixed therein an upwar-dly projecting pin 198 which projects through a hole in an ear 200 of a member 202 arranged for oblique sliding movement on the part 180 toward and from the front end of the thin gage 11 from the position of.

Fig. 1 to that of Fig. 2. The member 202 slides on ribs 204 formed on each side of the Jart 180 and carries at its front end the thick gage member 12. Movement of the thick gage 12 toward and from its operative position is efiected by movement of the rocking member 194 with the rock-shaft 78 to which it is fastened by a screw 195. As the pin 192 moves about 78 as a center, it acts through the link 196 to slide the thick gage 12 upwardly and forwardly, the link 196 having an upwardmovement upon the pin 198. As the slide 202 moves forwardly, the slight rotation of the pin 198 during its movement prevents the pin from binding in the car 200 as it moves vertically on the pin. By the mechanism just described, swinging of the pin 192 with the rocking member counter-clockwise by means to be described causes the thick gage 12 to be moved upwardly and forwardly into operative position, and the thin gage 11, through the link 190, lever 186, and link 182, to be moved rcarwardly out of operative position. Swinging of the rocking member 194 in a clockwise direction, of course, reverses the motion, causing the thick gage 12 to be withdrawn and the thin gage 11 to be moved forward into operative position. The operative position of the thick gage, however, is farther back of the point where the tacks are driven than is the operative position of the thin edge gage, so that when the thick gage is used the tacks will be located at greater distance from the shoe edge, as is desirable at the heel-seat. 't will be observed also that through the connections described the shaft 78 will be rocked to cause the wedge 64 to be moved out from under the wedge 63 when the thick gage is brought into operative position, so that the tacks will be completely driven when the thick gage is in use as it. is when lasting an end portion of the shoe. W'hen lasting the sides of a shoe with the thin 11 in operative position, the wedge 64 will be inserted under the wedge 63 to cause the tacks to be only partially driven, as is desirable in lasting the side of a welt shoe. Y

In lasting the sides of a shoe, tacks of a different kind from the kind. used in lasting the end of the shoe are required, the side lasting tacks being frequently much longer and having small heads and blunter points than those used for end lasting. The race-- way 16 (Fig. 3) is adapted to receive long side lasting tacks and the raceway 17 tacks of a different kind for use at the end of the shoe, for example, at the heel-seat. The machine provides for the automatic shifting of the raceways in conjunction with the shifting of the edge gages and the driver stop.

wedges. For this purpose a link 208 has a ball and socketconnection at 210 with the raceway, the link 208 is threaded into a link member 212 and is provided with a set nut 214. 'To provide an adjustable yielding operative connection bet-ween the outer end of the link member 212 and the operating member 194, a block 216 (Fig. 1 is adjustably secured in a recess in the member 194 by a cap screw 218 which passes through a slot in the member 194. Part of the block 216 underlies the member 212 and in the bl. ck 216 is mounted a spring plunger 219 (Fig.

5)..having a conical end which engages a similarly shaped recess. in the end of the link member 212 to form a pivot for the link and an operative connection between the link and the member 194. In case movement of the raceway should be obstructed, for example, by clogging of tacks between the raceway and separator, power movement of the member 194 may still take place without danger of breakage or straining of parts, the spring plunger 219 in that case merely passing partially or wholly out of the recess in the link 212. From Fig. 3 it will be seen that the plunger 219 is sufficiently eccentric to the fulcrum 78 of the member 194 to give the required movement of the raceway and that when the parts are in the position there shown the fulcrum 78, the plunger 219 and the ball joint 210 are substantially in a straight line, and also that the face of the member 194 along which the block 216 is adjustable is substantially perpendicular to this line. The block 216 can, therefore, be adjusted without materially varying the position of the raceway when the parts are in the position shown; such adjustment of the block, however, will vary the movement imparted to the raceway when the member 194 is moved and provides convenient and accurate means for alining with the separator the channel 17 of the raceway which is in operative relation to the separater when the lever is moved from the position of Fig. 3 to its other position. The tack channel 16 may be alined with the separator while the parts are in the positionof Fig. 3 by loosening the set nut 214 and turning the ball-ended portion of the link 212.

It will now be clear that control of the plaiting movements of the gripper may be effected by rocking the shaft 170 and that the movement of the

wedges

63, 64 to control the stroke of the driver, the shifting of the raceways 16, 17 to control the size of tacks, and the alternative positioning of the

edge

11, 12 for mutually exclusive use at the ends and sides of the shoe respectively to position the shoe for the reception of tacks at different distances from the shoe edge, may all. be effected by movement of the member 194 with its pivot shaft 7 8.

Movement of the member 194 is effected by power of the machine under control of the operator by mechanism now to be described, including a knee lever by which also the rocking of the shaft 17 0 to control the plaiting movements of the gripper is effected. A push bar 220 is slotted at 222 to receive a pin 224 on which is a roll 226 fitting the slot 222. The pin 224 is supported in upper and lower branches of a lever 228, both branches of which are splined on the shaft 170. The lever 228 is supported by a bracket 232 secured to lugs 234 on the column 2 by bolts 236. i The bracket 232carries a stop-screw 238 to limit outward movement of the lever 228 and a stop-screw 240 is threaded into the lever 228 in position to engage the column 2 to limit its movement in the opposite direction. To yieldingly hold the lever 228 in central or neutral position and to indicate to the operator when it is in that position, a spring plunger 242, the lower end of which is conical, is arranged in the lever 228 to engage a suitabledepression formed in the upper end of a flanged pm 244 mounted in the bracket 232 and held by a. set-screw 246. The flange of the pin. 244 engages a. guiding groove 248 in the lower branch of the lever 228. The bar 220 pivoted by a pin 250 to the mechanism already described.

The rocking member 252 mounted to turn loosely on the shaft 170 having bearings thereon which are respectively above and between the branches of the lever 228. The member 252 has an upward extension 260 formed to engage a vertical slot 262 in a sleeve or tubular shaft 264 surrounding the rock-shaft 170. An inward thrust on the knee pad 258 will move the bar 220 longitudinally and rock the member 252 and hence the sleeve 264. To hold the bar 220 in its forward position a spring plunger 266 (Fig. 11) if mounted in anenlargement 268 of the member 252 in position .to engage the column, and rocking movement of the member 252 is adjustably limited by stop-screws 27 0, 272 arranged in the member 252 on opposite sides of its axis of movement and in position alternatively to engage the column 2.

' On the upper end of the sleeve 264 is clamped at 274 a U-shaped member 276 which extends around a bearing bracket 278 for the shaft 170 and is loosely mounted on the shaft 170 above the bracket. upper face of the U-shaped member 276 is mounted pawl 280 in position to engage the teeth of a six-toothed ratchet wheel 282 loosely mounted on the shaft 170. Above the ratchet 282 and fixed thereto or integral therewith, is a three-projection cam 284. Above the cam, a block 286 (Fig. 3) is loosely mounted on the shaft 170, the block being embraced by a slot 288 in an operating slide bar 290 on the lower face of which are mounted two

rolls

292, 294 which are so spaced that when one engages a projection of the threeprojection cam 284 the between the ratchet teeth.

On the other will engage a portion of the cam between the other two projections. Rotary movement of the cam 284 will therefore im a part a reciprocating'motion to the operating slide 290, for, as one projection 296 (Fig. 3) leaves the roll 294, another projection 297 will engage the roll 292 and move the slide 290 forward until the cam has made one sixth of a rotation. Upon move ment of the cam another one sixth of a rotation in the same direction, the motion will be reversed. The forward end of the slide 290 is pivoted at 298 to the rocking member 194 at a suilicient distance from its axis of rotation 7 8 to impart to the member 194 the movement required to effect the shifting of the driver stop wedge, the raceways and the edge gages, as alreadv described. It will be observed that the ends of the projections on the cam 284 and a portion of the surface between the projections is concentric with the axis 170 of the cam, so that a slight movement of the cam when in the position of Fig. 8, for instance, will impart no motion to the slide 290.

In order to actuate the ratchet 282 and the cam 284 by powerof the machine, a pawl 300 is mounted by a pm 302 onan arm 304 formed on the bracket 22 secured to the wiper slide 20. The pawl 300 has a wear plate 305 on its forward end which normally slides back and forth, as the slide 20 reciprocates, in close relation to a parallel surface formed between two adjacent teeth of the ratchet 282, no movement being imparted .to the ratchet. The rearend 306 of the pawl 300 carries a wear plate 307 adjacent to which is a spring plunger 308 mounted in a boss 310 on the bracket 47 forming part of the frame 5 of the machine head. The

plunger 308 has a stem 309 extending -through the boss 310 and .provided with ad- 308 does not bear on the wear plate 307 and does not press the pawl 300 against a flat The slide 20 is therefore relieved of any friction due to the pawl 300 or plunger 308 during reciprocation of the slide in the normal operation of the machine. A pawl 314 is pivoted at 316 to ears formed on the machine frame, and at its outer end has two teeth 318, 320, the tooth 318 normally engaging a tooth of the ratchet to preventbackward movement there- A spring 322 is connected between a pin on the pawl 814 and a pin on the pawl 280 and serves to hold both pawls in engage-' ment with the ratchet 282.

When the operator desires to have the driver stop, raceways and edge gages shifted from the positions which they occupy for one kind of work to the positions required for another kind of work; he pushes rearwardly as neviously described.

upon the knee pad 258 and thereby, through the mechanism described, rotates the sleeve 264; slightly, causing the pawl 280 to rotate the ratchet 28:2 far enough to cause the tooth 320 of the pawl 31 1 to engage the tooth of the ratchet which previously was engaged by the tooth 318. This rotation of the ratchet is sufficient to cause the pawl 300, on the next rearward movement, to engage a tooth of the ratchet which it previously was unable to reach, and upon its next forward movement to turn the ratchet one sixth of a rotation and locate another tooth of the ratchet in position to be engaged by the tooth. 318 of the pawl 31 1. This movement of the ratchet causes the cam 23 1 to operate the slide 290 and effect the desired changes, The next inward movement of the bar 220 by the operator will, of course, restore the parts to their original position, the changes being initiated at the will of the operator and completed by power of the machine.

It will be noted that as the pawl 300 moves forward with the slide 20, the spring plunger 308, being relatively stationary, 'will bear nearer and nearer the rear end of the wear plate 307 and hence will have increased leverage to hold the paw 300 against the ratchet 282. This action prevents the sudden movement of the pawl 300 by the slide from effecting an overthrow of the ra chet which, if sufficient, would cause the slide on its next forward reciprocation to shift the parts ba ck to their original positions. Since, "as arranged, the plunger 303 does no offer any frictional resistance to the normal op eration of the slide, its spring 313 may be quite strong. If the operator pushes on the knee lever to initiate a shift while the slide is in its rearwardposition, as he is most likely to do with the machine momentarily stopped, hehas to overcome the pressure of the plunger spring 313 to move one of the ratchet teeth by the pawl 300. At this time, however, the spring has its least advantage in its a tion on the pawl so that the shift is "easy. The shift can be initiated in any position of the pawl, however, without objectionable effort.

The closing movement of the gripper is effected by movement of a. rock-shaft 330 (Figs. 5 and 7) which is mounted in a hearing 332 formed on the side of the updraw lever 82 and in a bearing 33 1 formed in one end of the updraw lever pivot 8 1. An arm of the rock-shaft 330 carries a spring plunger 338 which bears on the upper end of a gripper closing red 3 10. Another arm of the rock-shaft 330 is bifurcated to emrace the bearing 334 of the rock-shaft and carries a roll 346 which is acted upon by the edge face of th cam block 115 which constitutes the gripper closing cam. By this construction therock-shaft 330 partakes of the tipping movement of the updraw lever 32 and, in consequence, the end of the arm 342 by which the roll 3 16 is carried has a movement transverse to the face of the cam which, of course, has a fixed axis on the shaft 6. lVhen the roll 3 16 is mounted in the usual manner on the arm 3 1-2, it rictionally resists movement transversely of the cam as the up draw lever is tipped and not only retards movement of the updraw lever but also causes undue friction and wear of the roll and cam and of the rock-shaft bearings. To overcome these objections to the prior construction, the following construction is provided: A pin 3 18 on which the roll 34-6 is mounted is secured in the arm 3 12 and the portion of it on which the roll turns is longer than the width of the roll, so that as the up draw lever tips, the pin 348 can move through the roll while the roll remains in the same relation to the cam 115, that is, without relative movement of the roll and cam in the direction of their line of con-tact. To maintain the roll 346 constantly in proper relation to the cam, cooperating rib and groove formations are provided on the roll and cam. As shown, a rib 350 is formed on the roll 346 which engages a groove 352 formed in the peripheral face of the cam 115.

As shown in Fig. 1, the machine is provided with the usual counter-shaft 35% which is continuously driven from a source of power and has fixed thereto a friction disk 356. A cooperating disk 358 is forced toward the disk 356 by a wedge 360 raised by a treadle lever 362. A pulley 36% fixed to the disk 358 is belted to the pulley 7. The machine is preferably provided, as shown in Figs. 1 and 12, with stop mechanism similar to that disclosed in Letters Patent of the United States No. 1,356,408,

granted October 19, 1920, on my application.

This mechanism comprises a brake shoe 366 lined with a piece of leather 368 which is 1 formed at one end as a hook to engage one end of the shoe and is forced against the inner face of the rim of the pulley 7 to arrest movement of the shaft 6 at a predetermined point in the cycle, preferably when the gripper is open. The shoe 366 is pivoted to a lever 370 which is acted upon to operate the shoe by a spring detent 3'72 mounted on a member 37 4 which is arran ed to swing on an eccentric 376 on the shaft (3. A roll 378 on the member 374 engages a beveled end on a vertically movable trip rod 380. At the proper time in the cycle, provided the trip rod is in its normal depressed position, the eccentric 376 moves the member 374 radially while the roll 378 is in contact with the beveled end of the trip rod 380, forcing the detent 372 against the lever 370 and applying the brake. I

The trip rod 380 is connected (Fig. 1) by asplit clamp operated by a screw 382 to a member 384 which is pivoted at 386 to the treadle lever 362. Depression of the treadle to engage the

friction disks

356, 358 will concurrently lift the rod 380 and cause its beveled end to swing the member 374 about its operating eccentric 376 and release the detent 372 from the end of the lever 370, the brake shoe being then raised by a suitable spring (not shown). The beveled end of the trip rod 380 is maintained in operative relation to the roll 378 when the screw 382 is released to permit the machine head to be raised or lowered. For this purpose a sleeve 388 has a sliding fit on the rod 380 and provides a long bearing therefor to minimize wear. The upper end ofl'he sleeve is conical and engages a hole in a portion 390 of the frame, through which the rod ex tends, to centralize the rod in the hole. On the lower end of the sleeve is a framelike portion 391 through the lower end of which the rod 380 passes and between which andan adjustable collar 392 is arranged a spring 393 to depress the rod and naii' tain the sleeve 388 pressed upwardly into the hole in the frame. Within the frame 391 an arm 394 is clamped to the rod and has a slot 395 in its upwardly extending end which engages a fixed pin 396 on the frame. An adjusting screw 397 engages the pin and limits depression of the arm 394 and the rod 380. This pin and slot connection also prevents rotation of the rod 380 so that the operative relation of the beveled end of the rod to the roll 378 is maintained when the screw 382 is loosened. By merely loosenmg the screw 382 and clamp screw 398 (Fig. 1). which holds the neck of the machine head in the column, a

screw 399 maybe turned to adjust the head vertically, it being understood that the described splined connection between the rockshaft 170 and lever 228, and between the sleeve 264 and the arm 260, permits movement of the rock-shaft and sleeve with the head. V

In work on Mcl'lay shoes conditions are somewhat different from those which obtain when operating on welt shoes. In McKay work the tacks are all completely inserted; longer tacks are required for use at the ends ofthe shoe instead of at the sides as in welt work, and the tacks are all driven at the same distance from the shoe edge. These conditions are met by the construction shown in Figs. 8 and 9. The member 194 and the mechanism for operating it to effect the shifting of the raceways and edge gages are substantially the same as in the construction already described and the description need not be repeated.

A thin edge gage 400 is secured by a screw 402 to the frame 5 of the machine head. Threaded into therear end of the gage 400 is a screw 404 having a capstan head which quired.

ways relatively to the movement of the thick engages the frame. By loosening the screw 402 and turning the screw 404 the position of the gage 400 may be accurately adjusted to position the shoe to receive tacks at the desired distance from the shoe edge. A thick gage 406 is mounted on a carrier 408 which slides on inclined ribs 409 formed on the thin gage 400 and moves from a rearward position, where it is out of the way of the shoe, to a forward position where it presents the thick gage 406 with its work engaging face in the same position as that of the thin gage. To the rear end of the carrier 408 is pivoted at 410a member 412 having a depending arm 414 connected by a link 416 to a block 418 pivoted on a pin 420 secured in one end of a lever 422 the other end of which is pivoted at 424 to the member 194. Connection between'the link 416 and the block 418 is made by a .pin 425 fixed in the block 418 and arranged for lengthwise sliding movement in separated ears 4-27 on the rear end of the link (Fig. 8). This construction enables swinging movement of the lever to communicaterec tilinear movement to the gage carrier 408. it spring 426 is wrapped about the pivot 424 and has one end engaging the member 194 and the other engaging a pin 428 onthe lever 422; the lever can thus yield rearwardly relatively to the member 194, its forward movement by the spring being limited by a stop screw 429 on the member 194-. Couliter-clockwise movement of the member .194 from the position shown will cause the thick gage 406 to be moved foryielding connection of the lever 422 to the member 194 enables the movement of the n'iember 194to be suflicient always to move the gage carrier into operative position forward of the dog 430 whatever may be the adjusted position of the gage 400. anv excess movement of the member 194 being taken up by the spring 426. When the lever 422 is moved rearwardly, its pull on the link 4116 first rocks the member 412 on its pivot 410 to lift the dog 430 out of its position behind the carrier 408 to release the carrier and then moves it and the. gage rearwardly to inoperative position.

In McKay work it is customary to have the longtacks used at the ends of the shoe in the raceway 16, and of course the thick rest will be in use when long tacks are re- Hence the movement of the racegage is the reverse of that first described. Accordingly a link 411, by which the raceill) ways are moved, is pivoted to the member 194 at 413, as shown in Fig. 8, so that it will have received a push instead of a pull when the member 194 is turned counterclockwise. The raceway 16 will therefore be brought into operative relation to the separator when the thick gage is in use.

It will be understood that for McKay Work the driver stop Wedge 64 will be disconnected from its operating mechanism or both

wedges

63, 64 removed and a block of the thickness of the wedge 68 inserted to take the blow of the driver after the tack is completely inserted.

In l s ingim hine, ai him dg sees;

a thick edge gage movable relltivgl'y td-it thin gage into and out of operative position, power operated means for moving the thick gage into operative position, and means for locking the gage in said osition.

48. In a lasting machine, a thin et ge gage,

a thick edge gage movable relatively to the thin gage into and out of operative position, power operated means for moving the thick gage into operative position, means for lockmg the thick gage in said position, and means operated by reverse movement of the power operated means for unlocking the gage and returning it to normal position.

49. In a lasting machine, a thin edge gage and a thick edge gage arranged for alternative use, a carrier for the thick gage, power operated means for moving the thick gage carrier to move the thick gage into and out of operative position comprising a yielding lever, a locking dog engaging the car-- rier when moved by the lever into operative position and holding the carrier against movement in either direction, and means engaging said dog when the lever is moved in the opposite direction to release the clog and permit movement of the carrier.

50. In a lasting machine, an edge. gage carrier, power means for moving the carrier yieldingly in one direction and positively in the other direction, a stop to limit said movement of the carrier in the direction in which it is moved yieldingly, a positive lock for preventing movement of the carrier in the direction in which it is moved positively, and releasing means for disengaging the lock operated by the initial movement of the power means in the direction of positive movement.

51. In a machine of the class described, a column, a head vertically adjustable on the column, lasting instrumentalities carried by the head, a vertical rock-shaft, connections therefrom to some of said instrumentalities for controlling them, a slotted sleeve-shaft surrounding said rock-shaft, connections between said sleeve-shaft and other lasting instrumentalities for controlling them, a knee lever pivotally fixed to the column and splined to the rock-shaft, and a lever pivoted on the shaft and engaging the slot in the sleeve, said lever being connected to the knee lever and the head being adjustable without disturbing the connections between the rock-shaft, the sleeve shaft and the knee lever.

52. In a lasting machine, a column, a head vertically adjustable on the column, power operated lasting instrumentalities on the head, a rock-shaft extending from the head to a point on the column and having connections for controlling said instrumentalities, and a lever for operating the rock-shaft so connected to the rock-shaft that said shaft may be adjusted vertically with said head while the lever remains operatively connected to the shaft.

53. In a'lasting machine, a column, a head vertically adjustable on the column, power operated lasting instrumentalities on the head, controlling mechanism for said instrumentalities including vertical rock-shafts, and a control lever mounted on the column and operatively connected to the rockshafts so that either may be operated independently of the other, said operative connections being constructed and arranged to permit the head to be vertically adjusted without disturbing said operative connections.

54-. In a lasting machine, a column,a head vertically adjustable on the column, power operated lasting instrumentalities on the head, controlling mechanism for said instrunientalities including concentric rocking members, and a control lever mounted in fixed vertical, relation on the column and operatively connected to each of said memhere to rock them independently, said opertive connections being arranged to permit.

vertical movement of the members with the head without disturbing their operative connections to the lever.

In testimony whereof I have signed my name to this specification.
