JERSEY Application filed July 31,

This invention relates'to machines for contact With the foot or" the wearer of the shoe, or too much, unduly indenting the insole. An adjustment is therefore-provided for the drivers, they being threaded into their carrier and fixed in their adjusted relation by lock nuts or set-screws. An object of this invention is to reduce the time required for the operatorto make such adjustments. This I accomplish by providing a member common to a plurality of the drivers for retaining them against movement in the position to which they may be longitudinally adjusted. A single movement of this retalning member either releases or secures any number of I drivers upon their carrier, whereas with setscrews or lock-nuts, a separate operation would be necessary for each. As herein illustrated, a plate is employed, resting normally upon the top of the driver-carrying head and having a locking opening for each i driver. The lifting of the plate frees all the drivers for ad ustment, and its release causes them to be locked against rotation.

For various reasons, it may be desired to give the Operating ends of the drivers of heelattaching'machinestorms which are asymmetric with respect to their longitudinal axes. An example or this is furnished by the in dining ot the driver-surfaces which contact with the inserted nails to causesaid'nails to converge toward the axis of the heel to be attached, and thus permit them to be driven closer to the rand-crease. Another object of my invention is to maintain the correct relation of the driver-end formation to the jack and work. This I attain through the pronnnn-errncnrne Macrame Serial No. 296,559..

vision of means which releasably fixes each driver against rotat on in its carrier, with end formation in a predetermined angular relation. This means. may include a-projection from the driver, fixed in its angular relation to the inclined end or other asymmetric formation, and such a locking means as a plate having an opening through which the driver passes and an extension from the opening to receive theprojection, the extension, as-well as the projection, having a predetermined angular relation to the inclined surface. The projection and opening-extension can only cO-operate when the driversend iscorrectly positioned. This plate 'may be utilizedas the locking means for the drivers of the entire gang upon the carrier. The drivers are adjusted, as already indicated, by vlrtue or their threaded mounting upon their carrier. They are rotated to effect the adjustment by a tool entering the openings in the block in which the drivers move and engaging their ends-A, screw-driver engaging a slot in the operating end of each driver maybe utilized, but tends to give trouble because of its liability to displacen'ent from the slot. A further object of this invention is to facilitate the driver-adjustment. This I accomplish by forming-at one side of each driver-end a space furnished by a segment removed from'the driver at one side or the longitudinal axis. This space is thus adjacent to the wall or the opening inthe j ack-top Or other block in which the driver moves. 1 With the drivers having inclined ends, as herein disclosed, this space is prefer-- causes the projection of the tool to seat itself naturally in the space and "effectively resists driver-end also presents a maximum unbroken surface for engagement with the nail-heads.

A jack-body carries upon it a top or die-block 12, in the vertical nail-receiv ng openings 14 of which operate cyl ndrical drivers 16. These drivers are preferably threaded at 17 into a plate 18 carried upon a head or plunger 20 guided within the hollow body of the jack. To the head is oined a spindle 22, to which power is applied to reciprocate the drivers for the insertion of the nails N, which they bear upon th ir upper extremities, through the heel-seat of a shoe S into a heel H to be attached. In this nailinserting travel, the drivers move fro-m their lowest point, as illustrated in Fig. 2 of the drawings, to one shown in Fig. 1, in which their operating ends are at or just above the curved work-supporting surface 24 of the j ack-top. To cause the nails to be driven inclined inwardly from the heel-seat toward the longitudinal axis of the heel, the upper extremities of the drivers may be oppositely 1nclined at 26, or upwardly and outwardly from the axes of the jack and heel. The end of each driver is therefore asymmetric with respect to its longitudinal axis. This tips the points'of the nails in, so, as they emerge from the openings 14, they tend to follow the paths indicated in Fig. 1. Nails thus driven may be placed relatively close to the rand-crease without their points emerging through the side wall of the heel. A tight crease is thus obtained.

To originally produce the correct relation of the drivers to the j ack-to-p, or to adjust them vertically to compensate for wear, they may be raised and lowered by turning them in their threaded engagement with the plate 18., To prevent rotation of the drivers, and thus retain them in adjustment, there is provided a locking means, preferably common to all. Just above the upper surface of the plate 18, each driver has a projection 28. Normally resting by gravity upon the driverplate is a locking plate 30, through which is a-circular opening 32 to receive each driver, and a lateral extension 34 from each opening, which the corresponding projection 28 may enter. The angular relation of the inclined driver-surfaces 26, the driver projections 28. and the locking extensions 34 is such that, when the'projection is secured by being within the extension, the surface 26 is correctly inclined with respect to the vertical axis of the jack and the heel to be attached.

To permit the drivers to be turned, the plate is raised, as appears in Fig. 2 of the drawings. This frees the projections 28, and any or all of the drivers may be rotated in their threaded connection 17 to bring their upper ends to the desired levels. With the projections brought into alinement with the opening-extensions 34, the release of the plate 30 causes the extensions to again receive the projections and lock the entire driver-gang. This gang may consist not only of those arranged according to a single nailing design, such as is illustrated in the drawings, but also series for one or more other designs when multiple drivers are used. Such a second set of locking openings 32 is shown.

To turn the drivers, they are most convenientlyengaged by a tool applied to their upper ends through the jack-openings 14. For this purpose, a segment, preferably less in extent than half the upper surface of each driver-end, is cut away at 36, this being shown as at the low-er side of the inclined surface 26. This end-formation is adapted to cooperate with such a tool as appears in Figs. 4 and 5. A handle 40 carries a stem 42, upon which is a head 44. This head is con' plemental to the driver-end, having a cylindrical portion fitting the jack-openings 14, with a surface 46 inclined oppositely to the driver-surface 26 and substantially equal in size thereto. A projection 48 from the body is adapted to enter the space 36 in the driver. The body 44 is inserted within a jack-opening 14, in the manner illustrated in Fig. 4, and is lowered and turned until the projection 48 seats itself in the space 36. This engagement is readily efi'ected, and, being obtained, the tool is locked in place against displacement until it is lifted vertically. For application to drivers when their ends are outside the j ack-top, as at the time of their application to the plate 18, the driver and tool may be maintained in operating alinement by a sleeve 50 surrounding the stem and having an annular space 52 to receive the head 44 and the driver-end. This co-operation is particularly shown in Fig. 5.. In this way, the tool is as effectively maintained in alinement with the driver as when it is within the jack-opening. It is to be noted that, with the segment removed at 36 from the inner side of the driver-end and at the bottom of its incline, there is given, as a nail tips inwardly upon the driver, a substantially unbroken surface for engagement with a nail-head. This is less liable to mutilation than would be an end divided, for example, across the center, as by a screwdriver-slot.
