SPECIFICATION forming part of Letters Patent N o. 642,898, dated February 6, 1900.

Application tiled I une 3, 1899. Serial No. 719,270. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM H. DENMAN, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which- Figure lisa plan view; Fig. 2, a section on line 2 2, Fig. l; Fig. 3, a section on line 3 3, Fig. 1; Fig. 4, a plan view of a modiiication of the pad portion of the shoe; Fig. 5, a section on line 5 5, Fig. 4.

This invention relates to elastic-tread horseshoes; and its object is to provide a means for securing in a simple and eiiicient manner the pads or calks to the shoe.

The invention consists in the combination, with an ordinary metal horseshoe formed of an integral piece of metal, of a pad or pads of india-rubber or other suitable elastic or yielding material, that are secured to the shoe by means of a rivet having an enlarged head, that is contained ina corresponding socket or cavity in the body of the pad, and whose shank extends through a hole in the shoe and is secured to the latter, as hereinafter described, whereby, while the said pad or pads may be readily aflixed and removed,when the shoe is devoid of the saine it may be used as an ordinary metal shoe Without its utility for that purpose being affected.

In carrying out my invention, reference being had to the accompanying drawings, forming a part of this application, I make, by casting or forging, an integral horseshoe 1 of suitablemetal, which does not or may not differv in form from an ordinary horseshoe, except that it is provided with through-holes 2, usually onlyin the toe and heel portions, respectively.

3 are toe and heel pads or calks of elastic india-rubber, in which is formed a socket or cavity 4, adapted to receive the head 5qd of a metallic rivet 5, whose shank 5b is of considerably less diameter than the head 5a and eX- tends through the said hole 2 in the shoe, and its projecting end is turned over and riveted on the latter, as clearly seen in thedrawings.

I prefer to make the head of the rivet tapering, as shown, and I also prefer to provide on the end of the head a circular flange 5, so as to better insure the retention of the pad by the rivet.

. The purpose of having the head tapering, as shown, is to prevent the rivet from being forced against the animals hoof when the shoe is in use. Other means for effecting a similar result may be employed-as, for instance, by making the part adjacent to the iiange 5, encircled by the india-rubber, cylindrical or' straight-sided and of larger diameter than the shank, wherebysthe end next to the latter will abut against the shoe.

It will be obvious that by the described construction the pad will be securely maintained in place, and when it is worn out it may be readily removed by removing the shoe from the foot of the animal and then forcing out the rivet and a new pad may be substituted.

I remark that I usually embed the head of the .rivet in the body of the material composing the pad in the process of making or molding the latter. I also remark that it will be obvious that in case it shall not be desired to use the pads the shoe, with the holes therein, may be used as an ordinary horseshoe.

I sometimes extend the pads 3 to cover the 'whole face of the shoe-that is, the under side when the latter is on the animal-except along the line of the usual nail-holes 6, as seen in Figs. 4 and 5.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination with the horseshoe, of the elastic or yielding pad, the rivet having the enlarged head Within a corresponding cavity or socket of the pad, and its shank extending through a suitable hole in the shoe and hav' ing its projecting end turned over and riveted, and means limiting the protrusion of the rivet toward the animals hoof when the device is in use, substantially as and for the purpose described.

In testimony whereof I have' hereunto vaffixed my signature this 11th day of April, A. D. 1899.

WILLIAM H. DENMAN.
