UNITED STATES HORACE BEALS, OF EAST STOUGHTON, MASSACHUSETTS.

IMPROVEMENT IN METALLIC FASTENERS FOR LEATHER.

To all to whom these presents may come: y

Be it known that I, HORACE BEALs, of East Stoughton, in the county of Norfolk and State of Massachusetts, have invented an Improved Metallic Fastener or device for securing two or more pieces of leather at their points of juncture; and do hereby declare the same to be fully described in the following specifica'- tion and represented in the accompanying drawing, of which- Figure 1 denotes a side elevation; Fig. 2, an end elevation; Fig. 3, a top view; and Fig. 4, a bottom view of my said fastener. Fig. 5 is a view of the fastenerblank as it appears when struck from a sheet of metal.

All of the said gures are drawn on an enlarged Yscale in Vorder to more clearly show the invention. V l

In the said drawing, a denotes the head of the clamp or fastener, and b b the arms or shank thereof.

The object of my invention is to produce a simple, cheap, and effective device to be applied to the overlapping sewed seams of boots and shoes in order to more effectually secure such overlapping parts at their points ofjuncture; and such invention consists in making or stamping out the said device from a single piece of metal, and of the form as shown in Fig. 5, and subsequently bending or'swaging the arms or legs thereof into therequisite shape to constitute a single shank, to enter a single hole made through the parts to be connected, and so as to be readily upset, the Whole being a-s hereinafter described.

In carrying out my invention or making the said device I take a sheet of brass or other suitable metal of the requisite thickness, and by means of a cutter or die of the required shape, cut out a blank to form the device, of the shape as seen in Fig. 5that is, with a head and two projecting arms extending from the sides ofthe said head. The said arms are next bent inward, and so as to lap upon the under face of the head, and `next brought together and bent at right angles to the plane of the head, the inner faces of the arms abutting against each other, so as to form a single bifurcated shank to enter a single hole made for its reception in the leather. Furthermore, each of the said arms I make sharp at its lower or outer end, such ends having a semicircular 0r semi-elliptical shape in cross-section, as shown in Fig. 4, the object of such conformation being to enable the upsetting-tool to' enter between the said legs and readily spread or upset them against the leather when inserted within a hole made therein, the reduced extremities of the arms enabling them to enter the. leather more readily, and become better embedded therein when folded over or upset by the upsetting-tool.

I do not claim a device for fastening two or more sheets of paper together, as made of a single metallic band bent and formed as shown in Letters Patent No. 56,587, as I am aware that suchis not new, and differs very materially from my invention. g

What I claim as my invention is as followsthat is to say:

I claim, as an improved article of manufacture, my said improved device as stamped from a single piece of metal, with the head a, and legs b b bent and swaged into the form as described and shown, the same being for the purpose set forth.
