PEGGING AND SEWING JACK.

SPECIFICATION forming part of Letters Patent No. 440,483, dated November 1 1, 1890.

Application tiled April 19, 1890.

To all whom zit may concern:

Be it known that I, ROBERT T. LEMMoN, J r., of Mount Airy, in the county of Pittsylvania and State of Virginia, have invented certain new and useful Improvements in Pegging and Sewing Jacks; and I do hereby declare the following to be a full, clear, and exact d escription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form part of this specication.

My invention relates to an improvement in pegging and sewing jacks 3 and it consists in the construction and arrangement of parts, which will be fully described hereinafter.

The objects ot my invention are to form the spring-actuated lever in a single piece and hold it in any desired position by means ot a ratchet, and thus enable the last to be quickly adjusted and released, and to provide a support which will allow the frame to be usedin either a vertical or horizontal position, and thus adapt it to hold the last in position either for pegging or sewing at the will ot the operator.

Figure 1 is a side elevation of a device which embodies my invention complete. Fig. 2 is an edge view, the 'frame being shown in one position in solid lines and in another position in dotted lines. Fig. 3 is a vertical section taken through the upper end ot' the vertical support,showing the two sockets made therein.

A represents a suitable socket, which has a locking spring-actuated pin B attached toits upper end, and into this socket extends the vertically-adj ustable support C, upon the top of which the frame H is placed. Extending vertically down into the top of the support is a suitable opening or socket I, and extending horizontally through the top ot the support is a second socket G. Extending from the lower edge of the L-shaped frame H is a projection or tenon J, which extends into either the vertical or horizontal socket or opening, according to the position in which it is desired to use the frame. A fastening A is placed at the junction or intersection ot the said vertical and horizontal sockets, so that it will secure the tenon J in either the vertical or horizontal socket. It the frame is to be used in a vertical position, it is placed upon Serial No. 348,743. (No model.)

the top of the support, but it the frame is to be placed in a horizontal position so as to enable the last to be turned upon its side for the purpose of enabling the shoe-maker to sew the bottom to the upper, then the tenon or projection on the frame is passed into the horizontal socket or opening, and the i'rame is then held in a horizontal position. Springactuated locking-pins are used to lock the frame rigidly to the support, but any other form of device may be used for this purpose. By means of the spring locking-pins here shown the parts can be quickly fastened or loosened at the will ot the operator, and thus enable changes to be made from one position to another with but very little loss of time.

Pivoted in the upper end ot the L-shaped frame II is the L-shaped lever O, which has its upper end so shaped as to extend into, support, and lock the last in position in the usual manner. The lower and longer end ot this lever O extends through a vertical opening in the support N, and upon the outer edge ot this support is formed a ratchet Q, with which the end of the lever engages for the purpose of locking the last in position. The lever is so shaped as to engage with this ratchet as it is forced downward against the spring R, which bears against the under side ot thelever and returns it to position whenever it is left free to move. The outer tree end ot' the lever, by passing directly through the support, enables the lever to be made in a single piece and in the cheapest, simplest, and most durable form, at the same time that it enables the last to be more quickly locked in position and released than can be done where the parts are constructed in the usual man ner. The support for the toe of the last is made adjustable back and forth upon the frame H by means of a spring-actuated locking-pin of any suitable construction. This support acts as a guide for the vertical movement ot the free end of the lever II and prevents the lever from having any lateral movement or from becoming displaced at any time.

In order to prevent the last from becoming injured by having its edges from coming in contact with the upper end of the frame H, there is placed upon or secured rigidly to the lever above the top of the trame a plate T, which is so shaped upon its upper surface as IOO IVO

to conform to the shape of the top edge of the last. This plate forming a wide and long bearing for the last just at that point where the vmost wear occurs, the last is notbroken, split, or otherwise injured, as is always the case where no provision is made for protecting it at this point.

As will be seen, by making the lever in a single piece the straps, the screws, and the other fastening devices which have heretofore been employed are entirely done away with and the cost of the jack is very greatly reduced and its construction lightened and simplified. By making the frame removable from the support and enabling it to be used in both a horizontal and a vertical position theshoe that is being made can be turned into vthe most convenient position for the shoet maker,r thereby enabling him to work easily and rapidly.

While I here show the support vhaving a lvertical and al horizontal socket in its end and the last-supporting frame having a projection,

it Will be readily understood that this arrangement can be reversedthat is. the sup- 'port provided with a vertical and a horizontal projection and the last-supporting frame with a socket to receive the said projections- Without departing from the spirit of my invention.

yHaving thus described my invention, I

1. The combination ofthe L-shaped frame proj ecting ends pivoted together, and a vertical toe-support longitudinally and adj ustably secured at its lower end to the long end of the L-shaped frame, and a vertical rack-bar se-4 I -shapedframe having its longitudinal portion provided with apertures, an I i-'shaped lever having its vertical portion pivoted to the vertical portion of the saidframe and extending parallel therewith, I and a" toe-rest which has its lower end engage the horizontal portion of the frame and having a piniwhich extends into th'e said apertures of the frame, whereby it is longitudinally adjustable thereon, substantially as specified.

In testimony whereof I afiix m yvsignatu re in the presence of two witnesses.
