tica'ble to carry the outsole-stitching about them. Instead it is customary to secure this portion by a series of successively driven fas tenings at the time the outsole is laid, and

then stitch around the remainder of the sole.

By this practice, several difficulties are introduced. Since a number of fastenings must be used, a considerable time is consumed in their separate insertion, and they may not be most advantageously located with respect to each other and to the edge of the sole. The

work is held in the hands of the operator, and since the way in which the fastenings clinch depends upon the pressure, this clinch and consequently the manner in which the outsole and upper are drawn together may not be uniform, and are almost certain to differ from the stitcher in effect. An uneven crease results. This is increased by differences in curvature of the tread-surface of the 0 sole or irregularities in the bottom of the channel, which further disturb the uniformity of clinching. An object of the invention is to provide for the rapid insertion of the fastenings, uniformly positioned and 5 clinched.

fect, regardless of surface-irregularities. Therefore, the elements secured are held together with approximately equal force throughout the series of fastenings, produc ing an even crease, and since the tools act simultaneously in all the supports the operating time is short. I prefer also to locate the inserting or operating points definitely upon the work, as with respect to the edge of the sole operated upon. To this end, the supports are made yieldable in another direction, or transversely of the previously mentioned yield, their relation being determined by the contact of gage-surfaces with the work. As one way of arranging for these movements of the driver-support, it may be yieldable upon a carrier, which, in turn, is movable, upon a universal joint, on the frame of the machine.

As another feature of the invention, a substantially uniform inserting force is provided in connection with all the'inserting tools or drivers, whatever may be their position as a result of the yield under the influence of the work. This is accomplished in a novel manner by furnishing a spring for actuating each driver, which may besecured to the frame of the machine or some member common to all interfere with the movement of the support,

either in its yield longitudinally of the driver or about its universal joint, the preferred connection being through a lever fulcrumed upon the frame for each spring, to which lever the corresponding driver is joined by a link. There is a movable member which simultaneously tensions the springs, together with means which releases'the springs for action. Herein is shown as the tensioning means a reciprocatory member Carrying a group of pawls, one acting upon each driver. Associated with each pawl is a contact memher, which causes it to release its driver.

At the time of clinching a tack or other fastening, the resistance to driving increases over that required for the previous inserting action, tending to separate the abutment-surfaces between which the work is clamped. In apparatus of the character of that herein described, in which one of the abutment-surfaces is yieldable, this separation may be sufficient to produce an imperfect clinch. As a feature of the invention, I guard against this by a new combination of elements in 5 which the inserting member is caused to illcrease the pressure of the abutment 1 member'- I ,upon the-work, as by its movementinto -engagement with said abutment memben In the present embodiment of the invention, a yield'able driver-support has a contact-sun face, which is struck by a surface upon the driver reciprocating in the support to force said support toward the work just as the driver-stroke is being completed- At thistime, the support is carried forward slightly by thea'drivenincreasing the clamping pressure as the greatest resistance-to driving. .is en:

A column has secured at its top ahead 12, upon the upper face of which is mounted a generally semi-circular bracket 1 with its open side at the front of the machine. Upon this bracket are carried the tack-driving and inserting sections I, of which nine are here shown, though more or less may be employed in accordance with the requirements of the work. Arranged about a forwardly extending shelf upon the bracket, and separated from each other to correspond to the spacing of the tacks as driven in the work, are depressions 16 (Fig. 6), each furnishing the lower half of a socket for a universal joint, the upper section of which is provided by a ca 3 18 bolted upon the top of the bracket-shelf. Considering now a single inserting section, the socket contains a ball 20. depending from which is a. short bearing 01' carrier-sleeve 22. This sleeve passes through an opening at the bottom of the socket, projecting at the under side of the shelf. Arranged to slide through the sleeve is a tubular portion 24 of a driversupport or holder and work-engaging or abutment member 26 Between the top of the body of the support and a washer 28 bearing against the end of the sleeve 22 is a. helical spring 30 surrounding the portion 24. The effect of this spring is to hold the member 26 yieldably in its lowest position to receive the pressure of the Work which is raised against it upon a jack 31, the form and operating movement of which will be hereinafter described. The downward movement of the support is limited by a split sleeve 32 threaded upon its upper end and having a curved skirt 33 arranged to engage the exterior of the cap 18. By properly positioning these sleeves 32 upon the supports, the position of the latter may be made uniform with respect to the supporting surface of the jack or to the work thereon. Each sleeve may be clamped in its adjusted position by a screw 35 which draws the sections together. At the bottom of a downward extension 34 from the body of each support is an abutment-surface 36 (Fig. 9) for contact with the work, and in this surface is an opening 38 furnishing a nozzle through which tacks are driven. At the outer side of the opening is a gage member 40 adapted to contact with a sole-edge and thereby locate the nozzle at the desired point in the work. Its distance from the opening may be varied to correspondingly change the spacing of the tacks from the edge, it being guided by slotand-screw connections 42 upon the support and adjusted by a screw 44.

Movable within the tubular portion 24 of the body of the support is a driver-rod 46 having clamped in its lower divided end a driver 48. A clamping collar 50, which maintains the driver in the split end of the rod, may have a. flattened portion moving over a surface 52 upon the support-extension 34, and thus resisting the tendency of the driver-claim to turn. The driver is shown guided in the extension, its end entering a passage 5% which terminates in a split retaining quill 56. Tacks T are delivered for driving within this quill through a support-passage 58 and a tube 60 entering the passage from a distributing mechanism D mounted on a cap-piece 61 of the frame.

The extent of driving movement of the rod -26 is limited by a threaded collar (32 (Fig. 3) adjustably clamped upon its upper threaded extremity. This collar carries on its under face a cushion (i l, which may be of leather, contacting with the upper side of the support-collar 32. In a socket formed at the upper extremity of the drivorrod is seated the end of a strut or link 66, which enters a socket in a lever 68 fulcrun'ied upon an arm 70 projecting from the bracket let. Fixed in the arm is one end of a torsion-spring 72, the free end of which pres es against the lever 68 above the (ll'lVQf-Stl'tlb. This spring 72 exerts a constant tendency to force the rod 46 down until the cushion 64 contacts with the support sleeve 32, at which time the driver acts to insert in the work the tack held in the quill 56.

To tension the spring 7 2 in preparation for the inserting stroke of the driver, and then to release it for such stroke, the following mechanism is preferably employed. At the inner side of the collar 62 is a projection 7% provided with a shoulder '4 5 for engagement by a pawl 7 6 pivoted upon an actuating plate 78 and urged toward the projection by a spring-plunger 79. The plate 78 is secured to the lower extremity of a bar 80 guided for vertical reciprocation in the cap-piece 61. Upon the plate is carried one of the pawls for actuating each of' the drivers of the series. The shoulder upon each collar is guided laterally during travel of the projection 74 between upstanding walls 84;, 84 bolted to the support-collar 32 at opposite sides of a rib 85 therefrom (Fig. Engagement of the walls 8& with the pawl limits the angular movement of the support about its longitudinal axis. Thebar receives its reciprocation through a link 86, which joins it to a bell-crank lever 88 fulcrumedupon the head rounding a stud 124 atztheiadjacent end of-tlie 12 and having a roll entering a groove 90 in a plate 114.

W hen the operator depresses the treadle to start the machine, the shoulder 160 draws down the latch 1410 against the tension of the spring 1416, freeing the tooth 14 1 from the shoulder 142, and thus leaving the lower section 132 of the lever carrying the templet free. As a result of this, the springs 122 and 72 may now bring the gages against the sole-edge and position the nozzles, ready for the in ertion of the fastenings. To allow the templet to be reset after an inserting operation, the latch-shoulder 142 must have again come into engagement with the tooth 1 14; of lever-section 132. If the operator continues to hold down the treadle after tripping the clutch, the position of the bar 162 will prevent this re-engagement. I therefore connect the upper end of the bar to the cam-actuated lever 88 by a slotted link 169. During the final ascent of the bar 80 to its initial position, the inner end of the slot forces out the bar 162, and therefore the latch, until the shoulder 142 engages the tooth, again connecting the leversections.

To guard against the actuation of the inserting mechanisms before shoe is fully in place to receive the fastenings, locking mechanism is provided, this being controlled by the work. The stationary rear section 34 has associated with it a gage or back step 170, which is guided for movement in the bottom of the section and is mounted pivotally upon a. locking slide 172 movable horizontally upon the frame (Figs. 3 and 4). The locking portion of the slide is furnished by a piece 174:

secured to the main slide member. 1'4'2 by a slot-and-screw connection 175, and is capable of adjustment, by a screw 176, This adjustment varies the normal position of the back stop when the inner wall of a recess 178 in the contact piece 1741 bears against the opposed wall of recess 180 in a bar 182 guided for vertical movement in the frame. A torsion-spring 184, connected at its ends to the frame and to :1. depending tail upon the gage, acts both to allow said gage to yield upon its pivot with. the work as this is raised by the vjack, and also holds the slide 172 in engagement with the bar 182. Formed at the inner face of the bar is a rack 186, with which meshes a gear-segment 1.88 upon a lever 190 fulcrumed upon the frame and pivotally connected at its opposite end to the bar 162. As long as the elements are in the relation illustrated in Figs.

the end of the toe contacting with the gage- 170 forces the slide 172 in until the bar is freed, this releasing the rod 102 and permitting the treadle 100 to be depressed to start the machine.

As the resistance offered to the templet, in; thrusting out from their inmost positions sections at the front of the machine, may be unduly great, an adjustment for these is preferably furnished. Pivoted at opposite sides of the front of the head 12 is a pair of arms 192, 192 geared at 194 to move together (Fig. 8). The pins 110 of the outer sections enter slots 196 in vertically movable slides 198 at the forward extremities of the arms. A spring 200 holds each slide nor-v mally raised. it being capable of easy depres sion to facilitate the separation of these outer sections from the machine. Formed upon one of the arms 192 is an extension 202, at the end of which is mounted a handle 204. This, handle is arranged to be turned into clamp ing engagement with a segment-plate 206, which is fixed upon the frame and through a slot in which a reduced portion of the handle passes. By changing the angle of the extension 202 and securing it by engagement with the segment-plate, the outer sections may be moved in or out to correspond to the width of the shoe being operated upon.

The jack 31 rises from a carriage 208 movable into' and out of inserting position upon a table 210. This table is mounted upon the upper extremity of a slide 212 arranged to reciprocate vertically at the front of the column. A vertical adjustment may be given the table upon the slide by a screw and hand wheel-nut 214. A clamping screw .216 per- Inits jacks of various forms to be readily applied to the carriage. A handle 218 5 facilitates the movement of the jack between the work-receiving and the fastener-inserting positions. At the bottom, the slide 212 is connected by a link 220 (Fig 1) to a bellcrank lever 222 fulcrumed upon the column. The lower arm of the lever 222 is joined by a link 224C to a second bell-crank lever 226, the point of connection being variable by means of a slot-and-screw device 228. This allows the extent to which the jack is raised to be altered, correspondingly varying the pressure of the work against the abutmentsurfaces 36 of the nozzles. A vertical link 280 extends between the lever 226 and a bellcrank lever 232 fulcrumed upon the head and oscillated by the engagement of a roll which ber rotated by theshaft 92 and also having the groove =90. This mechanism effects the elevation of the jack, with the resulting pressure of the workagainst the inserting secgear 252 may turn somewhat upon the shaft .250. .Ingurrous shock to the mechanism will tions and its withdrawal to the normally do- 1 pressed position.

The distributor D may be of any form 7 suitable for the fastenings employed, for example that disclosed in Letters Patent of the United States No. 1,107,337, McFeely, August 18, 1914. The tack-holding drum 240 of this mechanism, which elevates the tacks for delivery to the tubes 60, may be oscillated from the bar 80 which carries the driver-actuating plate 7 8. A rack 242 upon "the bar (Fig. 3) meshes with a pinion 244 upon a shaft 246 journaled horizontally below'the' distributor. This, through reducing gearing 248, turns a parallel shaft 250, which has upon it a gear 252 meshing with a segmehtal gear 254 upon the drum. Since the weight and therefore the momentum of the drum in its oscillation is considerable, I interpose between the shaft 250 and said drum means for absorbing this momentum and "thus cushioning the shock produced by the reversalof movement The gear 252 is loose upon its shaft, and said shaft has, adjacent to the-gear, an enlargement 256 (Fig. 10). On the enlargement are fulcrumed opposite three-armed levers 2G0, 260. Each lever in- .cludes an arm 262 substantially parallel to the-shaft, upon which arm is a ball working in a socket furnished by divided block 264 arranged to play in ways 266 extending radially of the gear 252. 'The other two arms 268 of each lever are curved in opposite direst-ions, the ends of these arms upon both levers'normally lying in a common vertical plane. Against these ends a washer 270 surrounding theshaft 250 is forced by a spring 272, the outer end of which abuts against a washer 274 backed by nuts 276 threaded upon sition of these nuts, the force with which the .gspring presses the washer 270 against the levers 260 may be varied. It will be seen that the shaft/.250 drives the drum 240 through the levers 260, and that, long as the resistance or force exerted by the drum .does not exceed thatof the spring 272, the levers will not be displaced, and the shaft "250 and. gear 252 will move together as a unit. When however, there is an excessive stress, such as the resistance encountered in reversing the direction of rotation of the drum. this. transmitted through the levers, .will turn these and force outthe washer 270 against the spring, which will yield so the therefore be avoided.

Assuming thatthe toe-portions of the out- 5 soles of shoes are tobe' nailed to the insoles,

the end of the shaft. 7 By a change in the po the machine is provided with a'-=iack'\vhicl1 will enter properly into the particular sizes of'shoes being operated upon and will give, beneath the points of the securing tacks, a clinching surface. A templet' 154,- approximating in form that of the forward end of the sole, is placed upon the lever-section 132. A shoe S having been placed upon the'jack when this is in the position appearing in Fig. 1, it is forced into the point shown in Fig. 8. Here it finds the gages 40- of theinserting sections I held out of contact with it by the templet, the lever-section 132 being latched in by the member 140. The forward extremity of the sole, however, meetsthe back stop 170 and forces in its supporting slide'172 to release the treadle. The operator,'depressing this, starts the machine upon its insertingcycle by causing'the engagement of the clutch 94. The lowering of the treadle" releases the latch 140 by the action of the shoulder 160, so that the templet-carrying member 132 is freed to swing away from the inserting sections. Consequently, the side sections are carried in laterally by their springs 122 and 72 until t-heir gages 40 contact with thesole-edge and properly position the nozzle-openings 38 from said-edge, the correct distance between these openings being maintained by the links 116. "In this lateral movement the pawls '76 may share, turning about their pivots, and thus avoiding accidental release of the driver-rods 46, which they normally retain. T'he' jack is elevated and the sole pressed against the abutme'nt-surfaces 36 of the n07zles,the supports 26 yielding longitudinally of the drivers against the springs 30 to allow thenozzles to adapt themselves to irregularities of'the surface. The bar 80, first rising, causes the release of the tensioned springs 72 by withdrawal of the pawls 76. frombeneath the driver-retaining shoulders 75. under the influence of the contact-screws 106. The consequent descent of the drivers brings them against tacks T contained in the nozzle-quills 56, where theyhave been delivered at the proper time through the tubes from the distributor D. The sharp stroke of the. driv ers, under the influence of the springs, effectively forces the tacks into the sole. and, near the termination of their movement, the engagement of the, support-collars-32 by the driver-cushions 64 produces an additional pressure between the abutment-surfaces and the work, which gives :the proper resistance to the clinching force. Downward movement of the bar 80, followed by its rise to the normal position after the drivers have-thus=fnnctioned, causes the plate 78 to swing-the lever-- sections 130, 132 to reset the templet for the succeeding operation, said sections now being latched together at 142 and 144. That they should be in the correct relation for this l'atching, regardless of whether the operator had continued depression of the treadle, is insured by the action of the cam 90'upon the bar 162 through the link 169. During .the rise of the bar 80 and plate 78, the pawls 76 are in position to engage the driver shoulders 75, resetting the springs 72. The machine is now ready for another operation.
