CUSHION-TREAD HORSESHOE.

$PECIFIGATION forming part of Letters Patent No. 719,693, dated February 3, 1903.

Application filed February 24,1902. Serial No. 95,256.

(No model.)

To all whont it 'IH/(I/Z/ concern:

Be it known that I, ALBERT J .PUHL, acitizen of the United States, residing at J oliet, in the county of \Vill and State of Illinois, have invented certain new and useful Improvements in Cushion-Tread Horseshoes, of. which the following is a specification.

My invention relates to improvements in that class of horseshoes in which cushion and non-slipping devices are provided in combination with ametal horseshoe of substantially the shape of the common and well-known steel or iron shoes.

The special objects of my invention are to provide a shoe in which a durable and yielding pad is interposed between the upper face of the metal shoe and the animals hoof, in which soft and non-slipping calks are placed at the toe and heels of the shoe and project beyond the lower face of the latter, in which said pad and calks are attachable and held in place without the use of nails or other fastening devices separable from the shoe, and in which the calks may expand laterally, so as to relieve them in a measure of the full force of the impact with the surface of the roadway and at the same time serve to more securely hold them in position in the sockets in which they are placed.

Referring to the accompanying drawings, which form a part of this application, it will be seen that I have illustrated my invention in several views, as follows:

Figure 1 is a top plan view bodying my improvements. tom plan view of the same. elevation of the same. Fig. iis a side elevation of the same. Fig. 5 is a cross-section on the line 1 2 of Fig. 1. Fig. 6 is a cross-section on the line 3 4 of Fig. 1, but with the pad removed from the shoe; and Fig. 7 is a crosssection taken through a horses hoof from too to heel and through the shoe and pad, showing the relative positions of said parts.

Reference being bad to the drawings in detail, I represents a metal horseshoe formed on the usual side lines or contour and provided with the customary nail-holes N. Through the forward portion or toe of the shoe extends an opening A, the sides of which are beveled, as at S, so that the diameter of said opening is greater at the upper face of the shoe than of a shoe cm- Fig. 2 is a bot- Fig. 3 is a front at the lower face. Through the heel portions of the shoe extend openings B B, elliptical in shape and with their sides beveled, as at S. It will be noted that the rear wall of the openings B does not extend without interruption or break to the upper face of the shoe, but is met by an overhanging ledge b of the heel portion of the shoe, said ledge extending inwardly toward the center of the openings, as indicatedby dotted lines in Fig. 2.

It represents a pad preferably formed from canvas and rubber and conforming in contour to the shape of the shoe. Secured to or formed integrally with the pad are calks R R R the former located at the toe of the pad and the latter at the heel portions. These pads are elliptical in shape, somewhat smaller than the openings A B in the shoe; but the sides of the calks are parallel, and their longitudinal and cross diameters are equal to the shortest diameters of the openings A and B, respectively. Near the rear end of the calks R and just below the pad B said calks are cut away, as at 1' sufficiently to receive the ledge 11 when the parts are assembled. The vertical diameter of the calks is such that when in place the lower portion of same projects through the openings in the shoe and extends beyond the lower face of the latter, whereby they receive the impact of the contact of the horses foot with the roadway.

The pad and calks are applied to the shoe by inserting the ledge 19 in the opening r then' pressing the toe and heel calks into their appropriate openings A and B, respectively. When weight or pressure is applied to the shoe, the calks will expand laterally and occupy the space 5 provided between the straight walls of the calks and the sloping or beveled walls of the openings or sockets A B, thus serving to bind the calks in place and increasing the resiliency or cushion efiect of the construction shown.

By interposing a pad between the animals foot and the upper face of the shoe I prevent to a greater or less extent the jar that the animal would otherwise receive, it being understood that while the calks receive and resist the initial impact they do not entirely sustain the weight of the animal.

From the construction described it will be seen that as the cushion device is not per- I oo manently or fixedly attached to the shoe it does not interfere with the shaping of the latter to the horses foot by heating and hammering in the usual manner. The pad with its calks is not assembled with the shoe until after the latter is ready to be applied to the animals foot. It will also be seen that no nails, screws, or other means requiring the use of tools are required to attach the pad to the shoe.

Having thus described my invention, What I claim as new, and desire to obtain by Letters Patent, is

1. In a horseshoe the combination of a metal shoe having toe-call; and heel-call: openings'therethrough, said heel-call: openings having inwardly-projecting ledges or flanges, and an elastic pad provided with toe-calk and heel-calks extending through the corresponding openings in the shoe, said heel-calks having portions cut therefrom to receive the projecting ledges or flanges of the shoe, substantially as set forth.

2. In a horseshoe, the combination of a metal shoe having toe-call: and heel-calk openings therethrough, said heel-call; openings having inwardly-projecting ledges or flanges at their rear edges and having inclined sides, and an elastic pad provided with toe-call; and heel-calks extending through the corresponding openings in the shoe, said heel-calks having portions out therefrom to receive the projecting ledges or flanges of the shoe, substantially as set forth.

In testimony whereof I affiX my signature in presence of two Witnesses.

ALBERT J. PUHL.
