HENRY WATERS, OF BISBEE, ARIZONA TERRITORY.

SHOE-REPAIRING JACK.

SPECIFICATION forming part of Letters Patent No. 631,885, dated August 29, 1899.

Application led October 18, 1898. Serial No. 693,926. (No model.)

To a/ZZ whom, it Iii/ay concern:

Be it known that I, HENRY WATERS, a citizen of the UnitedStates, residing at Bisbee, in the county of Cochise and Territory of Arizona, have invented certain new and useful Improvements in Shoe-Repairing Jacks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to repairing-jacks for shoelnakers; and the object is to provide a simple, inexpensive, and convenient device of this character.

To this end the invention consists in the construction, combination, and arrangement of the several parts `of the device, as will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a side elevation, partly in section, of my improved shoe-repairing jack. Fig. 2 is a perspective detail view of the separable or adjustable last. Fig. 3 is a horizontal section on the broken line a a of Eig. 1. Fig. 4 is adetail View of one of the extensionpieces.

1 denotes the base-plate, which is securely bolted to the work-bench, and it is provided with a central orifice for the reception of the stud-shaft 2, formed integral with the standard 3, which is adapted to rotate on its axis in the base-plate 1.

The upper end of the standard 3 is formed with a rectangular funnel-shaped pocket L to receive the correspondingly-formed shank 5 of the last-bracket 6, and the upper end of the last-bracket is formed with a V-shaped recess 7 to receive the correspondingly-formed lower end 8 of the block 9.

The converging faces of the block 9 are provided with integral dovetail V-shaped tongues 10 and 12, which engage correspondinglyformed grooves 13 and 14 in the contiguous faces of the sole-block 15 and heel-block 1G, which form the last proper.-

Extension-pieces 17 are formed each with a corresponding tongue and groove, as shown, and are inserted between the block 9 and heelpiece 16 to elongate the last when necessary.

18 18 denote semicircular studs extending g upwardly to receive the sockets 19 19, formed on the contiguous lower edges of the soleblock 15 and heel-block 16.

2O denotes a swivel-joint formed in the lower portion of the shank 5, and 21 denotes a sheet-metal spring having its upper end ixed to the toe of thelast-block 15, while its lower end is notched to engage the screw 22, which is adj ustably secured thereto, and after a shoe is placed on the last this spring is drawn down to fill out the instep and assist in retaining the shoe on the last. n

While the accompanying drawings show my invention in the best form now known to me, many changes in the details might be made within the skill of a good mechanic without departing from the spirit of the invention as set forth in the claims hereto appended.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a shoe-repairing jack, the combination with thelast-bracket 6 and the sole-block 15, of the instep-spring 2l having its outer end fixed to said last-bracket, substantially as shown and described.

2. In a shoe-repairing jack, a fixed baseplate, a standard mounted thereon and having its upper end formed with a pocket, the last-bracket 6, seated in said pocket, the solei block 15 removably secured to said lasti bracket, and the instep-spring 21, having one end fixed t0 said sole-block and the other end adj ustably secured to said last-bracket, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY WATERS.
