Fig. 17 is a plan view of the wiper; and' Fig. 18 is a perspective view of a shoe after it has been side lasted by the machine, showing the upper fastened to the sole by tacks along the shank portion and by cement at the forepart.

The invention is illustrated as embodied in a machine of the type disclosed in the above-mentioned Letters Patent and accordingly only such features of the general organization as it is necessary to refer-to for an understanding of the invention will be described herein in detail.

It will be understood that the shoe on its last is supported in the hands of the operator and is presented successivelyin different positions in the progressive lasting of its opposite sides. To assist in determining the proper relation of the shoe to the lasting instrumentalities the machine is provided with an edge gage 28 arranged to engage the side of the shoe at or near the edge of the insole and with a shoe bottom rest 22 arranged to engage the outer face of the insole.

The machine is provided with .a gripper compris ing a pair of cooperating jaws 24 to which the usual closing, updraw and overdraw movements are imparted by mechanism which is substantially the same as that shown in the above-mentioned'Letters Patent. For wiping the marginal portion of the upper inwardly over the insole. there'is provided a wiper 25 mounted on a slide 28 which is movable along a horizontal guideway in the head 30 of the machine and is operated by a cam 32 (Fig. 1) on a cam shaft 34 journaled in suitable bearings in the head 30. The'shape of the cam 32 is such that one complete reciprocation is imparted to the slide 28 in each cycle of operations of the machine to cause the wiper 26 to wipe the marginal portion of the upper inwardly over the outer face of the insole and to withdraw. It will be understood that when the wiper is in its rearward position a tack is fed from one or the other of a pair of raceways 36, 38 (Fig. into a tack pocket 40, formed in the wiper, from which it is driven by a driver 42 after the completion of the forward movement of the wiper.

The tack driver 42 is fastened to a driver bar 44 which is movable in a guideway formed in a carrier 46 journaled for swinging movement on trunnions 48, the journals being formed in a bracket 50 fast to the head 30. The slide 28 carries an adjustable screw 52 (Fig. 2) the head of which is arranged to engage an abutment 54 on the carrier 46 near the end of the forward movement of the slide 28 and to swing the carrier 46 with it, thus alining the driver 42 with the tack pocket 40 in the wiper 26' and maintaining such alinement during the remainder of the overwiping operation. The driver bar 44 is raised by a cam 56 on the shaft 34 against the resistance of a torsion spring which acts through an arm 60 and a strut 62 to impart tack driving movement to the driver 42 when the driver bar is released by the cam to the action of this spring after the completion of the forward movement of the wiper 26 and the slide 28. a

It will be understood that the

raceways

36 and 38 are adapted to receive tacks of different lengths and that the machine provides for automatic shifting of'the raceways to bring one or the other of them into operative relation to '

raceways

36 and 38 at their upper end are pivoted in the front wall of a tack pot 64 and at their lower end are connected by an adjustable link 66 to arblock 68 which is adjustably secured to an irregularly shaped rocking lever by a cap screw 72. Mounted in the block 68 is a springpressed plunger 14 (Fig. 11) having a conical end which engages a similarly shaped recess in the end of the link 66 to form a pivot for the link and an operative connection between the link and the lever 18. The lever 18 is fulcrumed on a vertical shaft 16 (Fig. 3) mounted to turn in bearings i8, 88 on the head 36, the lever 10, as shown in Fig. 12 being formed to embrace the bearing 78.. Movement of the lever 10 to shift the

raceways

36, 38 and to control the kind of tacks delivered to the wiper 26 is effected by power of the-machine under the control of the operator by mechanism which is substantially the same as that shown in the above-mentioned Letters Patent No. 1,623,279 and accordingly, need not be described herein in detail. It will be understood that either

raceway

36, 38 may be moved into operative relation to the tack separating mechanism and the wiper 26 and that when in that relation the end of the raceway is in alinement with a tack slot 8| in a throat plate 83. The tack slot 8! terminates in an eye 85 through which the tack drops into the tack pocket 40 in the 1 wiper. Between the throat plate 83 and the end of the raceways is a separator 81 which is reciprocated once in each cycle to separate the endmost tack from that raceway which is in tack supplying position. After the tack has been sep arated it is moved by the separator along the slot 8! and into position to drop through the eye 85 into the tack pocket 48. The machine as thus far described is constructed substantially as heretofore.

For purposes of this invention there is provided mechanism which may be rendered operative at will for imparting to the wiper 26 at the end of each overwiping movement a hammer blow to cause the Wiper to force the overwiped margin of the upper into firm adherence to the outer face of the insole in lasting the shoe with cement instead of with tacks. The wiper 26 is pivotally connected to a bracket 82 which is secured to the slide 28 by screws 84 (Figs. 6 and '7). In the construction shown the rear end portion of the wiper is forked to straddle 2. depending lug 86 on the bracket 82 (Fig. 13) and mounted in one of the arms of the forked end of the wiper is a spring-pressed plunger 88 which is arranged to engage a lateral projection 98 on the bracket 82 and to hold the wiper in engagement with a shoulder 82 on the bracket. The wiper 26ihas fast thereon a plate 93 provided with a rearwardly extending arm 94 arranged to engage a substantially L-shaped member or plate 96 adjustably secured to a lever 98 pivoted at I (Figs. 4, 5, and 1G) to a bracket I92 having a tongue-and-groove connection with the head 39. and fastened to the head by a screw I94. When the plate 853 is in the position shown in Figs. l, 4, and 6 it acts by engagement with the arm 9-3 to hold the wiper against swinging movement relatively to the bracket 82 with the wiper in engagement with the shoulder 92 on the bracket. the wiper there is provided a hammer I96 (Figs. 6, 7 9) which is arranged to engage the head I83 of an upwardly extending arm III of the plate 93. The hammer Hit is pivoted on a stud I I2 (Fig. 9) secured to the slide 28 and is operated by a torsion spring Ii one end of which is connected to a member IIE which may be turned to adjust the tension of the spring and is held in adjusted position with teeth H8 on the member H8 in engagement with recesses formed in the end of the stud i I2 by a screw I29 threaded into the stud. The hammer IfiIi is provided with a real-wardly extending arm I22 arranged to engage an adjustable stop, illustrated as a fiber washer 524, to limit operative movement of the hammer, the fiber washer being carried by an adjustable screw 22% (Figs. 6 and '7) threaded through a boss I29 on a plate I 39 secured to the head 39. A lever or latch I32 pivotally mounted on the slide 28 and held in engagement with an abutment I34 on the hammer by a spring I36 acts normally to hold the hammer I55 in an elevated position with its operating spring I I4 under tension.

The machine is provided with mechanism for operating the latch I32 to release the hammer I86 to the action of its operating spring H4 at the proper time in the cycle of the machine and for moving the plate Q into a position in which the arm 94 of. the wiper is moved out of engagement with the plate near the end of the forward movement of the slide 28, thereby releasing the wiper for swinging movement in response to the action of the hammer I88 thereon. Fast to a shaft I453 mounted to turn in bearings I42, I44 on the head of the machine is a hand lever I46 (Figs. 1, 3, and a). Secured to the upper end of the shaft I43 is an arm I 38 connected by a link I59 to an arm I52 formed on a sleeve I54 rotatably mounted on the shaft 15. Formed on the sleeve IE4 is a second arm I55 connected by a link I55 to an arm I56 clamped to the upper end of a shaft I62 mounted to turn in a bearing I4 formed on the head 33 (Figs. 2 and 3). Secured to the lower end of the shaft I52 is an arm I66 connected by a short link I68 to an arm I19 on the lever 98. When the parts are in the positions shown in Fig. 4 with the member 96 in position to lock the wiper 25 against swinging movement relatively to the bracket 82, the arm 63 and the link 568 are in a substantially straight condition with a stop I12 on the hand lever I 35 in engagement with an abutment I14 on the head Movemen of the hand lever I46 from the position shown in Fig. 4 to the position shown in Fig. 5 swings the member 923 through the connections above described into a position in which the rearwardly extending arm 94 of the wiper is moved out of engagement with this member in the forward movement of the slide 28, the construction being such that the wiper is thus released for swinging movement relatively For imparting a hammer blow to to the slide near the end of the overwiping movement of. the wiper. Fast to one end of'a rockshaft I mounted in the head of the machine is a rearwardly extending arm I16 (Figs. 1, 6, and '7) having its end portion formed as an abutment I18 and fast to the opposite end of the rockshaft I 75 is an upwardly extending arm I89 carrying an adjustable screw I82. A spring I84 extending between an arm I85 fast to the shaft I15 and the head 39 tends to swing the shaft I15 and the arm I89 in a direction to hold the screw I82 in engagement with the edge face I86 of a cam plate I88 which is secured to the hand lever I46 by a screw I9il.- The shape of the edge face I86 (Figs. i and 5) is such that as the hand lever is swung in the direction to move the mem-v ber 96 into the position shown in Fig. 5 the shaft I15 is rotated through the sw'nging of the arm I80 in a direction to move the abutment I18 from the position shown in Fig. 6 to the position shown in Fig. 7. With the abutment I18 in the position shown in Fig. 7, as the slide 28 1s moved forwardly an upwardly extending arm I92 on the latch I32 is moved into engagement with the abutment so that in the continued forward movement of the slide 28 the latch I32 is swung against the resistance of the spring I36 out of engagement with the abutment I34 on the hammer m5, thereby releasing the hammer to the action of its operating spring II 4, the arrange ment of the parts beingsuch that the hammer is thus released substantially at the end ,of the for-. ward movement of the slide 28. With the return of the parts to starting positions the hammer I95 is swung reversely in the direction to tension its operating spring by the engagement of a roll I94 on the arm I22 with an inclined face I9Ii on the plate I30, the inclination of the face I96 being such that the hammer is swung far enough in the return movement of the slide 28 to permit the latch I32 again to engage the abutment I34 on the hammer I95. I 7

Forward swinging movement of the hand lever I l-'6 is limited by the engagement of a stop 290 on the hand lever with a fixed abutment 292 on the head 39. When the hand lever is swung forwardly from the position shown in Fig. 4, the arm I69 fast to the shaft I62 is swung in a clock wise direction. Secured to the shaft I62 is an arm 294 provided with a cam slot 296 concentric with the axis of the shaft I 62 (Figs. e and 5). Formed on a bracket 2238 (Figs. 2 and 3) on which the raceway supporting block 2H] is mounted is a bearing 2I 2 for a rockshaft 2M having secured to its upper end an arm 2I6 provided with a lug ZIS extending into a central recess 229 formed in the raceway supporting block 2 I9 (Figs. 4 and 5). Fast to the lower end of the rockshaft 2M is an arm 22?. carrying a roll 224 which is ar ranged to enter the cam slot 296 in the arm 294 as this arm is swung in a clockwise direction with the arm I60. As the arm 2M engages the cam roll 224 in the cam slot 296 the arm 222, through the rockshaft 214 and the arm H6, is swung in a direction to cause the raceways 36, 33, through the engagement of the lug 2|8 with the raceway supporting block ZIS in the recess 22% in the block, to be swung into a neutral position (Fig. 5) in which position neither raceway is in alinement with the tack slot III in the throat plate 83 so that no tack will be delivered from either of the raceways through the tack-separating mechanism to the wiper 26. When the hand lever I46, therefore, is swung forwardly to the position shown in Fig. Eg'tho feeding of the tacks is interrupted by the movement of the raceways into a neutral position. For holding the hand lever I46 in its rearward position with the stop I12 in engagement with the abutment H4 or in its forward position with the stop 200 in engagement with the abutment 202 there is provided a spring 203 (Fig. 1) connected at one end to a pin 205 projecting from the head 30 and at the other end to a pin 20! carried by an arm 209 on the sleeve I54.

The illustrated machine is' further provided. with means for stopping the operation of the driver 42 in response to the forward swinging movement of the hand lever I46. Formed on the driver bar 44 (Fig. 3) is an abutment 225 and pivotally mounted on the bracket 5!! is a latch 228 for engaging the abutment to prevent operative movement of the driver bar 44. Fast to a slide 232 movable in a guideway in the bracket 50 is a stop 230 arranged by engagement with a laterally extending arm 234 on the latch 228 to hold the latch normally out of engagement with the abutment 226. The arm 234 of the latch is held in engagement with the stop 230 by a spring 236 extending between the arm and the bracket 50. Projecting downwardly through an enlarged opening in an arm 238 on the stop 233 is a pin 240 which is threaded into an arm 242 on the sleeve I54 and is provided with a nut 244 for locking it against endwise movement in the arm 242. As the hand lever I46 is swung forwardly from the position shown in Fig. 4 the sleeve I54 is rotated in a clockwise direction to move the stop 230 to the left (Fig. 3) out of engagement with arm 234. Movement of the stop 230 out of engagement with the arm 234 permits the spring 236 to swing the latch 228 into a position beneath the abutment 226 to prevent operative movement of the driver 42. It will be understood that as the hand lever I46 is swung rearwardly from the position shown in Fig. 5, the stop 230 is moved to the right (Fig. 3) in response to counterclockwise movement of the sleeve I54. As the stop 230 is moved to the right it engages an inclined face 246 on the arm 234 and swings the arm in a direction to move the latch from beneath the abutment 226 to permit the operation of the driver. 7

It will be understood that the position of the shoe laterally is determined by the edge gage 20 which is arranged to engage the shoe substantially opposite the edge of the insole. In lasting a shoe with cement the position of the shoe laterally should preferably be such as to cause the wiper to act on the marginal portion of the upper over substantially its entire width to wipe it inwardly over the insole and to press it into position to adhere thereto. Since the tacks are usually inserted substantially midway between the edge of the shoe bottom and the edge face of the overlaid margin of the upper in lasting with tacks, the illustrated machine is provided with means under'the control of the operator for adjusting the edge gage rearwardly to extend the wiping efiect of the wiper when lasting with cement. For this purpose the edge gage 20 is adjustably secured to a member 248 slidably mounted on the bracket I02 (Figs. 1, 2, 10, 15, and. 16). The member 248 carries an adjustable screw 250 which when the parts are in the positions shown in Fig. 10, is held by a spring 254 extending between the member 248 and the bracket I02 in engagement with a curved face 252 on the lever 98. A plate 256 having a tongue-and-groove connection with the slide 248 is adjustably secured thereto by a screw 258 threaded into the slide and extending through a slot in the plate. Fast to the plate 256 is a stop, illustrated as a pin 260, having its upper end portion cut away to provide a flat surface for engaging the end flace 262 of the bracket I02. Fig. 10 shows the parts in the positions that they occupy when the machine is used for lasting a shoe with tacks. When it is desired to last a shoe with cement the lever 98 in response to the forward swinging movement of the hand lever I46 is swung from the position shown in Fig. 4 to the position shown in 'Fig. 5. As the lever 98 is thus swung the slide 248 and the edge gage 20 are moved rearwardly by the spring 254 until the stop 260 engages the end face 262 ofthe bracket I 02. It will be seen that by adjusting the plate 256 relatively to the slide 248 the rearward position of the edge gage 20 may be varied to vary the position of the shoe laterally and thereby to vary the extent of inward movement of the wiper over the bottom of the shoe as may be necessary to take care of variations in the width of the lasting margins of the uppers of different shoes. It will be evident that with the parts in the positions shown in Fig. 5 rearward movement of the gage 20 is prevented by engagement of the stop 260 with the end face 262 of the bracket I02. When the hand lever M5 is swung rearwardly the lever 98 is swung into the position shown in Fig. 4. As the lever 98 is thus swung the slide 248 and the gage 20 are moved against the resistance of the spring 254 forwardly by the engagement of the curved face 252 of the lever 98 with the screw 250, the construction being such that the lever 98 is held against reverse swinging movement to prevent rearward displacement of the gage 20' by the positions of the arms I66, I10 and the short link I68. It will be evident that the position of the shoe laterally may be varied to vary the distance from the edge of the shoe bottom at which the tacks are inserted by adjusting the screw 250.

It will be understood that when the hand lever I46 is in the position shown in Fig. 4 the machine is set to wipe the marginal portion of the upper in each lasting location over the outer face of the sole and to drive a tack from the wiper at the end of the overwiping operation to fasten the upper to the sole. When it is desired to last a shoe, or a portion thereof as, for example, the forepart, without tacks, the hand-lever I46 is swung forwardly to the position shown in Fig. 5. Forward swinging movement of the hand lever moves the abutment I'I8 into latch-tripping position, causes the

raceways

36, 38 to be moved into a neutral position, the arm 98 to be swung in a direction to move the locking plate 96 into a position to release the wiper 26 for swinging movement substantially at the end of its inward movement and to permit the spring 254 to move the edge gage 20 rearwardly, and also moves the stop 230 into a position in which the latch 228 is released to the action of the spring 236 for engagement with the abutment 226 to prevent operative movement of the driver 42. With the hand lever in the position shown in Fig. 5, the machine is set to wipe the marginal portion of the upper over the sole and to operate the wiper substantially at the end of its overwiping movement by a hammer blow to cause it to force the overwiped margin firmly into adhering relation to the outer face of the sole, to the marginal portion of which, and to the marginal portions also of the upper, cement has previously been applied.
