UNITED STATES PATENT OFFICE.

WILLIAM BILLINGS, OF BROOKLYN, ASSIGNOR TO ABRAHAM W. GODFREY,

OF NEW YORK, N. Y.

IMPROVED PEGGING-JACK.

Specification forming part of Letters Patent No. 4 2,61 S, dated May .0, T864.

To all whom t may concern:

Be it known that I,.WILLIAM BILLINGs, of Brooklyn, in the county ot' Kings and State ot' New York, have invented a new and Improved Pegging-Jack; and I do hereby declare thatthe following is a full, clear, and exact descliption of the same, reference being had to the accompanying drawings, forming apart of this specification, in which Figure l represents a longitudinal vertical section ot' my invention. Fig. 2 is a plan or top vi'ew of the same.

Similar letters of reference indicate corres` onding parts in the two views.

This invention consists in a swinging bar, the gud geons of which are adjustable in different notches in the edges of the uprights which form their bearings, in combination with an adjustable screw passing through the standard which supports the heel end of the last in such a-manner that by means ot' said movable bearings and adjustable screw the swinging bar can be readily adjusted for lasts of dit'erent size and. shape, and that said lasts are rmly supported at the heel and at the toes.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a bed-plate, ot' cast-i1 ou or other suitable material, from which rises the standard B, the upper end of which is provided with a pivot, a, to tit into a corresponding hole in the heel-plate of a last. This standard maybe cast solid with the bed-plate or otherwise rigidly attached to the same, and through its lower part passes freely the thumbscrew O, which is tapped into a lug, D, rising from and cast solid with the bed-plate A. The point of this screw bears on the lower end ot' the swinging bar E, which serves to support. the toe part ot' the last.

The upper end ot' this swinging bar is provided with a toe, b, and its upper surface corresponds as near as possible to the upper surface of the toe part ot' the last or lasts to be supported. It has its tulcrum on gudgeons c, which are cast solid with or otherwise firmly .eonnegted toit, and these gudgeons have their bearings in notches d in the top edges of the uprights F. These uprights are cast solid with or otherwise rigidly attached to the bedplate A, and the notches d are made as close together as possible. By means ot' these notches and ot' the adjusting-screw the swinging bar can be readily brought in such a position that its upper surface adapts itself perfectly to the toe part ot' the last to be supported, and by these means the boot-jack is applicable for lasts of different shape and size.

The whole device can be made very cheap. The bed-plate A, standard B, lug D, and uprights F can all be cast solid, and no fitting or other labor is required, except what is needed to make the thumb screw Ll and tap it into the lug D, and by its'use a Shoemaker is enabled to use one and the same jack for va- -rious sizes of lasts and to have a hrm support for each last which is placed on the jack.

What I claim as new, and desire to secure by Letters Patent, is-

The adjustingecrew (l, in combination withV the standard B, swinging bar E, and adjustable gudgeons c, all constructed and operating in the manner and for the purpose substantially as herein shown and described.

Witnesses: WILLIAM BILLINGS.
