IMPROVEMENT IN SHOEMAKERS JACKS.

Specification forming part of Letters Patent No. 119,675, dated October, 1871.

To all whom t may concern:

Be it known that I, FRANZ WnrssENBoRN, of Egg Harbor Oity, in the county of Atlantic and State of New Jersey, have invented a new and Improved Shoemaliers7 Jack; and I do hereby declare that the following is a full, clear, and eX- act description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification. I

Figure l represents a side elevation, partly in section, of my improved shoemakers7 jack, the line o c, Fig. 2, indicating the plane of section. Fig. 2 is a detail transverse section of the same on the line k k, Fig. l.

Similar letters of reference indicate correspond ing parts.

My invention consists in the improvement of shoemakers jacks, as hereinafter fully described and subsequently pointed out in the claim.

A in the drawing' represents the frame of the jack, secured at its lower end to the floor of the apartment in which it is put up. B is a crossbeam, journaled at its ends in the upper end of the frame A. C is the jack, swiveled by a bolt or pin, D, to the crossbeam. E is the post for supporting the last F. It is iitted into the jack O in such manner that it may be swung more or less outward or inward, a spring, a, which is concealed within the jack, holdingl it inward-that is, vertical to the face of the jack. Gr is the rest for supporting the toe of the last. It is provided with a slotted plate, I), projecting toward the post E and fastened to the jack by a bolt, d, that penetrates said plate b. The rest is thus adjustable on the jack to admit of longer or shorter lasts. The plate b, projecting under the last, is out of the way of threads or other things used in the manipulation of boots or shoes. One end of the cross-piece B carries a notched tooth or segment, e, into which a spring-bolt, f, sliding in a post of the frame A, is locked for securing the crosspiece in any desired position. A handle, g, for withdrawing thebolt from the segment, projects downward, so that the shoemaker can reach it with the knee, permitting him thus to turn the last to the right or left without taking the han ds from the work.

The last can, on the horizontal axis of the crossbeam B and on the vertical axis of the swivel-jack, be conveniently turned in either direction to bring the boot or shoe in the most convenient position for handling. The bolt d, it will be seen, passes only through the metallic bottom plate lzy of the jack, said plate having a cylindrical depression, i, ttin g into a cavity of a plate, j, that is secured in the cross-beam. When the jack is turned on the cross-beam it turns in the plate j, leaving the bolt entirely undisturbed, and preventing thereby the jarring and working' oft of the nut atthe lower end of said block.

H is a receptacle or drawer for holding' tools, ndings, Sto.

VHaving thus described my invention, I claim as new, and desire to secure by Letters'Patent- The notched tooth e, spring-bolt j', and lever g, arranged with respect to the frame A and beam B, as and for the purpose specified.

FRANZ WEISSENBORN.
