Application filed March 13, 1926. Serial No. 94,494.

This invention relates to shoes for horses in winter time to prevent them from slipping, and to avoid concussion at all seasons on any hard roads; and it consists of a heel pad secured to the shoe as hereinafter fully described and claimed.

In the drawings, Fig. 1 is a plan view from below of a shoe provided with a heel pad according to this invention; Fig. 2 is a plan View of the pad from above; Fig. 3 is a section through the pad, taken on the line 33 in Fig. 2; Fig. 4 is a cross-section through the shoe and the pad, taken on the line 44 in Fig. 1; .and Fig. 5 is a plan view from above of one heel portion of the shoe, and is drawn to a smaller scale.

The shoe 8 is formed of metal, and has the usual standard nail-holes. Any sort of a toe calk 9 can be provided, such as a solid calk, or removable oalks of any sort, as for instance tenon calks which fit into tapering holes in the shoe.

The heel portions of the shoe are provided with pear-shaped lateral enlargements 1O having downwardly projecting ribs 12 at their outer sides, and downwardly projecting corrugations 14 on their inner portions having each two holes 15 in them. These corrugations form depressions 16 of irregular shape in the upper side of the shoe. Pockets 12' are formed at the front ends of ribs 12. The heel pad 18 is formed of relatively soft material, such as india rubber composition, which is vulcanized on the shoe, and which retains a substantial amount of elasticity. This pad extends across the space between the heel portions of the shoe, and over their upper surfaces and the outer sides of the ribs 12 which it covers in thin plates 19.

The upper side of the heel portions of the shoe and the upper side of the pad between them are covered with india-rubber composition 20 and a facing sheet 21 of canvas or other similar textile material. The composition 20 impregnates the canvas, and is joined onto the thin composition plates 19 in a solid mass or sheet, so that the heelportions of the shoe are wholly embedded in the rubber composition, which also fills the holes 15 and connects the composition above and below the corrugations.

The heel of the animals hoof rests on the canvas facing 21, and the shoe is secured in place in the usual way.

The under side of the pad is provided with circular or semispherical cups 22 and smaller depressions 23 over the heel portions of the shoe, and between the cups 22 and forwardly thereof the pad is provided with a large heart-shaped conical depression 24 having inclined inner and outer side walls 25. The pad has flat heel surfaces 26 around the cups 22 and depressions 23 which project below the level of the parts 25. The depression 24 projects towards the toe of the shoe, and has a rounded bottom. The outer side of the inclined side wall is convex at the front side of the depression 24,and the rear inner side of the depression has a longitudinal forwardly extending projection 27. The conical depression 24 is larger and deeper than the cups 22, andits rounded, bottom has only a small thickness of composition between it and the canvas facing 21. The rear part of the pad has a concave outer side 28 behind the conical depression 24.

This shoe prevents slipping on any kind of road, and .as it breaks concussion it enables the horse to travel with case on hard roads. the heel pad will prevent slipping .on icy streets in winter, and with a dull toe call: the heel pad will prevent slipping on wet or oily pavements in both summer and winter. These shoes can be used for several weeks as a sharp shoe for ice, and when the heel pads'are worn too low for sharp calks the shoes can be used for several weeks more as summer shoes.

What I claim is:

1. A cushioned horeshoe, comprising a metal shoehaving pear-shaped lateral enlargements which form its heel portions, said enlargements having downwardly projecting ribs at their outer sides and downwardly projecting corrugations on their inner and end portions which form depressions on the upper side of the shoe, and

a pad of soft material extending under and between the said pear-shaped enlarge ments and filling the spaces between the said ribs, said pad extending also over the upper sides of the said enlargements and filling the said depressions.

2. A cushioned horseshoe, comprising a metal shoe having laterally enlarged heel portions, and a pad of soft material extend ing around and. between the said enlarge VVithsharp toe calks on the shoe ments and providedwith flat-surfaces having substantially semispherical cups in them arranged under the enlargements, said pad having also a conica'ldepression arranged forwardly. of and between the: said cups, said depression being of greater area and depth than the cups.

3. A cushioned horseshoe as set forth in claim 2, the said conical depression having an inclined convex outer side at its front 10 slgnature.
