UNITED 5%TATES P'Aiflfih it ENOCH P. MEAD, OF SALT LAKE CITY, UTAH.

SHOEIVIAKE Specification of Letters Patent.

Application filed July 10, 1911.

To all whom it may concern Be it known that I, ENOCH P. MEAD, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Shoemakers Jacks, of which the following is a specification.

My invention relates to devices with which shoemakers hold shoes for repairing, commonly called a shoemakers jack, and my purpose is to provide a jack for that purpose which may be easily and quickly turned to any position enabling the shoe repairer to nail on the heel or half sole or to sew the sole on the shoe or any part thereof without loss of time in moving or changing the position. These objects I accomplish with the device illustrated in the accompanying drawings, in which similar figures of reference indicate like parts throughout the several figures.

Figure 1 is a vertical longitudinal sec tion. Fig. 2 is a vertical elevation with the shoe in place thereon. Fig. 3 is a vertical front elevation of the jack with the standard part of the jack shown in horizontal position in dotted lines.

My device consists of a vertical standard having a foot or base 2 and the upper portion of said standard enlarged in form of a socket 3. lVithin said socket are cut the longitudinal slots 4 through which is placed, and in which is made to operate, the crescent clamp 5. Near the central part of said crescent is secured the upper end of a threaded rod 6 carrying a spiral spring 7 and a nut 8 on the lower end thereof; also secured on the lower end of said rod 6 is the foot lever 9, a portion of which extends without the base 2 through an open slot 2 cut therein. lVithin said base 2 are provided the inwardly extended lugs 10 and pivotally fulcrumed thereto is said foot lever 9. Extending within the lower end of said standard 1 is the plate 18, the purpose being to hold the said spring 7 from upward movement on the rod 6. Within the socket 3 is placed the ball 11 of the laststandard 12. On said standard 12 is placed the last 13, in the instep part of which is RS JACK.

Serial No. 637,737.

pivoted a spring lever 14 made to engage in an open cut within the upper end of said last-standard 12, the purpose being that when it is desired to remove the last from the standard the said spring lever may be turned to one side, which movement will release the said last 13 from the standard 12. The said spring lever 14 is made of flexible material and is designed to be located with in the shoe when the shoe is placed on the last. The tension of the said lever 14 will ordinarily hold the shoe on the last while it is being repaired. If desired and for more securely holding the shoe, a flexible strap 15 is passed over the shoe, the lower end of which strap is engaged by the lever 16, which lever has openings 17 therethrough in which a hook link 19 is made to engage at the diflerent holes as desired.

In use, a shoe to be repaired is placed on the last 13 in the usual way, and it may be held thereon by the spring lever 14; or as hereinbefore recited if more security is desired the strap 15 placed therearound may be locked by pulling the lever 16 in the position shown in Fig. 2, first having adjusted the tension desired by the hook link 19 being placed within one of the said holes 17. The ball and socket joint between the ball 11 and socket 3 enables the operator to turn the shoe to any position from the vertical or horizontal and to rotate it to any extent desired. By pressing on the said lever 9 the tension of the spring 7 is released, and removing the pressure on said lever will allow thetension of spring 7 to hold the arms of the crescent 5 in close contact with said ball 11 and prevent any movement whatever of the standard 12 and last 13.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. A shoemakers jack consisting of a last of a pedestal, the upper end of which is in I form of a socket and having slotted openings therethrough, a crescent shaped clamp adapted to move in said openings, a lever pivoted tothe base of said pedestal, a rod connecting said crescent shaped clamp and said lever and carrying a spiral spring thereon, a plate also carried on said rod and adapted to hold said spring, and a standard having a spherical base seated in the socket of said pedestal. 10

In testimony whereof I have affixed my signature in presence of two Witnesses.

ENOCH P. MEAD. Witnesses:

SAM RANEY, W. R. WILLIAMS.
