TOOL FR FINISHING SHOE-SOLES.

To all whom z' may concern.'

Be it known that I, FRANKLIN O. THOMP- soN, a citizen of the United States, residing at Meredith, in the county of Belknap and State of New Hampshire, have invented a new and useful Tool for Finishing Shoe- Soles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the` art to which it appertains to make and use the same.

This invention relates to a new and useful shoemakers tool.

As one of the objects of the invention, it is the aim to provide a tool of this nature, which may be operated by any suitable power (not shown), which is adapted to be belted to the operating shaft of the tool.

A further object of the invention is the provision of such a tool for burnishing and finishing the heels, shanks, edges, and the bottoms of boots and shoes and the like.

Another object of the invention is to heat the burnishing parts of the tool by friction.

In the drawings are disclosed certain features of construction, but in practical fields these features may necessitate alterations, to which the patentee is entitled, provided the alterations are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed..

In the drawings Figure 1 is a view in elevation of the improved shoemakers tool constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view.

Referring more particularly to the drawings 1 designates a shaft, to which power may be furnished by any suitable means, such as gearing or belting (not shown), in order to rotate the tool. This shaft is provided with a spline seat or groove 2, which receives the shank of the set screw 3 carried by the sleeve 4, so as to cause the sleeve to rotate with the shaft 1. One end of the sleeve is provided with an annular enlargement 5, from the periphery of which an annular fiange 6 projects. Between the outer circumference of the sleeve 4 and the flange 6 an annular space 7 is formed, in which the coil spring 8 is seated. Partially telescoping the flange 6 is a sleeve 9,-the outer end portion of which terminates in ,an enlarge- Specification of Letters Patent.

ment 10 having a beveled periphery 11, and provided with an annular groove 12.

Fitting on the shaft 1 beyond the sleeve 4 is a collar 13, which is formed or constructed with a spline seat or slot 14, into which the spline screw 15, which is threaded in the enlargement 10, eXtends, so as to cause the ,y collar 13 and sleeve 9 to rotate as one.

The bevel 11 constitutes means to assist in burnishing and finishing shoe soles, that is, l one of the edges thereof, while the beveled =surfaces 16 assist in finishing and burnishing the other edge of the sole, whereas the bead or ridge between the bevels 16 forms or constructs a slight depression in the sole of the shoe, in order to make a line of demarcation between the welt of the shoe and the sole. The bevels 16 are constructed on a disk 18, and the bead or ridge is denoted by the character 19. This disk 18 is provided with an extension 20, to be received by the collar '13, and extending through the disk and the extension is a screw 21, which is threaded into the shaft 1 of the tool, so as to cause the disk 18 to rotate with the shaft. In this manner also, owing to the fact that the disk 18 engages the collar 13, said collar is firmly clamped between the disk 18 and the sleeve 4. In this manner it will be seen that the collar 13, the disk 18 as well as the sleeve 4 all rotate substantially with the shaft 1, and by arranging or holding the edge of the shoe sole between the bevels 11 and 16, the proper burnishing and finishing may be imparted to the shoe sole. In s0 doing the bevel 11 of the enlargement 10 of the sleeve 9 bears yieldably against the edge of the sole of the shoe, as will be seen in the drawings, owing to the fact that the coil spring is interposed between Vthe enlargements 5 and 10. When motion is imparted to the shaft 1 by any suitable power, whether by hand or otherwise, preferably belt-ing or gearing, and the tool is correspondingly operated, a metal finger, such as that indicated in the drawings and adapted to be held stationary enters the groove 12, and by a frictional contact therein, the entire enlargement 10, and especially the bevel 11 becomes highly heated through friction.

Having set forth the invention, it is to be noted there has been devised a novel construction of shoemakers tool, and one which has been found particularly desirable and practical.

The invention having been set forth, what is claimed as new and useful is l.' In combination, a revoluble shaft having a burnishing and finishing tool revoluble therewith, the tool having a yieldable member provided with an annular groove, into which a device extends, whereby frictional heat is generated as the tool revolves.

2. In combination, a revoluble shaft, a

sleeve including an enlargement having a ment and a portion of the member, and a device extending into the groove to generate frictional heat in the member when rotating.

3. In combination, a revoluble shaft, a disk revoluble therewith and provided with a beveled periphery having a bead, a yieldably mounted member having connections with the shaft in order to rotate therewith andprovided with aV beveled surface between which and the beveled periphery of the disk the edge of a shoe sole is adapted to be arranged, for burnishing and finishing the same, and means for generating frictional heat in the yieldably mounted member.

In testimony whereof I have signed my a name to this specification in the presence of two subscribing witnesses.

FRANKLIN O. THOMPSON.
