' J. WASHCO' SHOEMAKERS TOOL Filed Oct. 15; 1924 Patented Apr. 20, 192$.

UNITED STATES JOHN WASHCO, OF WILKES-BARBIE, PENNSYLVANIA.

SHOEMAKERS' TOOL.

Application filed October 13, 1924. Serial No. 743,377.

To all whom it may concern:

Be it known that I, JOHN Wnsrroo, a citizen of the United States of America, and resident of l/Vilkes-Barre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Shoemakers Tools, of which the following is a specification.

This invention relates to shoemakers tools, and has for an object the provision of novel means for cutting grooves or seats in the outer surfaces of soles of shoes to receive fastenings, such as stitching or the heads of nails, by which the sole of the shoe is secured in place.

It is an object of this invention to provide a tool, the cutting blade of which will be guided to travel parallel with or concentric to the edge of the sole and operative to produce an incision or out which is diagonal to the edge of the sole.

It is the purpose of this inventor to pro duce a knife or blade which will produce an undercut in the sole in order that the leather may be turned up and back to produce a channel in which the sole fastenings, whether stitching, nails or pegs, may be imbedded and concealed when the leather which has been displaced to form the channel is replaced and secured by appropriate,

adhesive.

It is a further object of this invention to produce a cutter of the character indicated having a blade with a cutting edge in such relation to a guide as to insure proper undercutting when the slit is being made.

It is a still further object of this invention to produce a blade which is removably secured to the body of the cutter in order that the said blade may be removed for the purpose of sharpening it, or to renew blades that have become impaired or worn. It is a still further object of this invention to associate with the cutter of the character indicated a leather engaging device which may be used as a screw driver or for displacing the leather after the sole has been out.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in whichi Figure 1 illustrates a view in elevation of a cutting tool embodying the invention;

Figure 2 illustrates an end view thereof; Figure 3 illustrates a perspective view of the blade or knife; and

Figures 4 and 5' are perspective views illustrating the application of the invention during the cutting and leather manipulating processes.

In these drawings, 10 denotes a head having a shank 11, which may be secured in any suitable handle such as 12. The shank and. the handle are details of construction which may be changed to suit particular requirements, and need not be described more fully. The head 1.0 has a flat curved extension 13, the end 1 1 of which constitutes a guide which is intended to engage the edge of the sole of a shoe when the cutter is being used. The extension 13 has a recess or notch 15 formed in its edge which produces a clearance for the blade or knife 16. The blade or knife has a shankor plate 17 integral with it that is secured to the extension 13 by fastenings 18, such as screws or the like, so that by the removalof the screws, the blade may be removed for the purpose as stated.

It will be seen from an inspection of the drawing that the blade proper extends diagonally with relation to the plate or shank 17 and with relation to the surface of the guide 14:. This relation of parts permits the guide to engage and ride along the edge of the sole of the shoe while the knife or blade is extending downwardly and inwardly with relation to the said edge. The result ofthe operation of the device when working on soles of shoes is that the knife will extend inwardly and downwardly to produce an undercut in the sole of the shoe in order that the leather may be displaced by forcing it upwardly and inwardly to form a channel 19, in which stitching or nails will be imbedded. Thereafter the displaced leather will be returned to its normal position to cover the stitching and to conceal the fastenings.

The head has an integral extension 20 which may be used as a screw driver, or it maybe inserted in the cut produced by the knife to displace the material when the channel is being formed.

The head of the tool and the integral parts thereof may be formed by ordinary stamping processes, and therefore, the device can be manufactured expeditiously and at cornparatively small cost.

I claim: c 1. In a sole cutting tool, a head having a flat extension Whose end constitutes a guide,v

the said extension having its edge recessed to form a seat, a plate secured to the head and extending to the recess, a blade integral with the plate extending diagonally with respect to the said plate through the seat of the extension, and means lor securing the plate to the head;

2, In a sole cutting tool, a plate-like head having a flat plate-like lateral extension with a recess in its edge, the said extension beyond the recess constituting a guide, a plate lying against the head and secured thereto,

a blade integral with the plate and extending diagonally with respect to the plate, the

said blade projecting through the recess of the guide and terminating beyond the side surface of the gulde, and means for securing the plate to the head.

JOHN Was'nco.
