HORSESHOE-CALK.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application led January 1'7, 1905. Serial No. 241,516.

To L7/Z whom, it may concern.-

Be it known that I, JESSE S. MAeooN, Jr., a citizen of the United States, residing at Charlton, in the county of Worcester and State of Massachusetts, have invented a new and useful Horseshoe-Galli, of which the following is a specification.

This invention relates to that class of horseshoe-calks which are intended to be replaced as frequently as worn out.

The special object of this invention is to provide a horseshoe-calli with a removable shell which is held in place by the resilience of spring metal.

A further object of this invention is to provide ahorseshoe-calk with acushion for taking up jar.

To these ends this invention consists of a horseshoe-calk and its removable shell as articles of manufacture and of the combinations therewith, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective view of a horseshoe equipped with horseshoe-calks according to this invention. Fig. 2 is a detail view of one of the calls, the shell being shown in section. Fig. 3 is a sectional view of the removable shell. Fig. i isa bottom View thereof, and Fig. 5 is a side view of the calk with its shell in place.

In that class of horseshoe-calks to which this invention relates it has already been proposed to use detachable calks which are threaded into the horseshoe by the use of threaded studs for this purpose, and it is now possible to renew the calks of a set of shoes comparatively quickly and without danger of injuring the horses hoofs.

The special object of my present invention is to further improve this class of horseshoecalks by the use of replaceable shells which are preferably slotted or provided with gripping-fingers of sufficient resilience to hold the shells in place when they are forced over the heads of the studs or projections mounted in the horseshoe.

Referring to the accompanying drawings, the shoe A may be of the ordinary or approved construction. Y In the shoe A are four calks. Each of these calks, as illustrated more clearly in Figs. 2to 5, inclusive, consists of a threaded stud 10, having a collar 11, with a substantial ball shaped head 12. A replaceable shell which I employ for renewing or refitting a horseshoe-calli is tted up with a shell of substantially acorn shape-that is to say, each of these shells is pointed at one end and is provided at its other end with an inwardly-bent resilient gripping iiange or fingers 14.

In the particular form of shell illustrated in the drawings the closed end of the shell is provided with a sharp point. This particular shape of shell is used when it is desired to keep the horseshoe -calk sharp during slippery or icy weather, for summer use, and on bare ground. The closed end of each shell instead of being pointed may be somewhat flattened to provide a larger wearingsurface. By means of this construction when a shell has been `hammered or forced over the head of a stud it will grip itself firmly in place. When the calk becomes worn, the old shell can be taken oli" by means of pipe-tongs or other tools, and a new shell can then be forced into place. By this means it is possible to reequip a set of horseshoes very quickly and eficiently.

In some cases, in order to cushion the horseshoe-calks, I interpose a small piece of rubber, as 13, between the head of the stud and the shell.

I am aware that changes may be made in the shape and proportions of the parts of a horseshoe-calk constructed according to my invention Without departing from the scope thereof and as expressed in the claims. I do not wish, therefore, to be limited to the construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

1. As an article of manufacture, a replaceable cover for the horseshoe-calli consisting of a metal shell closed at one end and having a crimped-in holding-flange at its other end.

2. As an article of manufacture, a horseshoe-calk consisting of athreaded stud having a substantial ball-shaped head and a replaceable cover consisting of a substantial acornshaped metal shell having a point at one end and resilient gripping-fingers at its other end.

3. As an article of manufacture, a cushioned IOO horseshoe-@211k consisting of a threaded stud In testimony whereoflhavehereunto set my having a substantial ball-shaped head, a rehand in the presence of two subscribing witplaeeable cover consisting of e substantial nesses.

acorn-shaped metal shell pointed et one end JESSE S. MAGOON, JR. 5 and provided with resilient fingers at its other Witnesses:

end and a piece of rubber interposed between PHILIP W. SOUTHGATE,

the head of the stud and its cover. E. M. ALLEN.
