SPECIFICATION forming part of Letters Patent No. 415,003, dated November 12, 1889.

Application filed May 24:, 1888. Serial No. 274,983. (No model.)

To all whom it may concern:

Be it known that I, MARTIN S. STARK- WEATHER, a citizen of the United States, residing at Boston, in the county of Suolk and State of Massachusetts, have invented certain new and useful Improvements in Horseshoe- Pads, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in pads or cushions of the kind used in connection with metal shoes and adapted to be fastened in place by the nails which secure the metal.

It pertains more particularly to pads or cushions intended for use upon the front hoofs, although the use is not limited to such application.

Figure 1 is a bottom plan view of a pad embodying my improvements. Fig. 2 is a top view of the same. Fig. 3 is a side view showing the pad and metal shoe in place upon the hoof. Fig. 4. is a longitudinal section on the line so, Figs. 1 and 2. Fig. 5 is a cross-section on the line y y, Fig. 1. Fig. 6 is a bottom view of a modified form.' Fig. 7 is a top plan view of the same. Figs. 8 and 9 are respectively a longitudinal and a cross section on the lines a1 and y y', Fig. 6. Fig. 10 is a face view of another modified form of pad. Fig. 11 is a section on line y2 y2, Fig. 10. Fig. 12 is a section on line 002 002, Fig. lO.

II the drawings the metal shoe is indicated by The rubber pad or cushion is formed with a flat thin base part having its outer line ward-extending arms B B.

conform substantially to that of the shoe, there being a front curved part B and rear- Through these iiat thin parts B B B are passed nails, which fasten the metal shoe A in place. With them there is formed integrally a calk or comparatively large, strong, downwardly-extending rubber projection, (indicated as a whole by C.) It consists of a main or base part c, extending from one side part B to the other, a projection o at the front having its longitudinal lines arranged transversely of the pad as a whole, and a second transversely-arranged projection or downwardly-extending rib c2, these and the part c being bounded by a continuously vertical wall or shoulder C3, which fits squarely against the inner edge of the metal shoe. Between the projections or ribs c c2 there is formed an aperture D, which in the forms shown in Figs. 1 to 4 extends entirely through the pad, The side walls of this aperture at d d are preferably beveled or tapered, so as to avoid the forming of sharp corners, that would be liable to rapid wear. The ribs or projections c c2 provide the toe calk or calks, by which the foot of the horse has a firm grip upon the ground and slipping forward or backward is prevented. Lateral slipping is prevented by the parts at c4 c5.

By providing the parts just described-that is to say, by having a comparatively deep recess or a through-aperture at these placesthe pad or cushion can be caused to engage with the corners or upwardly-extending parts of stones or other projections in the road-bed, and where the road-bed is comparatively smooth the gripping is attained by the calks c c2 c4 c5, one preventing slipping in one direction and each of the others in another.

I am well aware of the fact that heretofore use has been made of rubber pads with iat thin base parts, each lying between the metal shoe and the hoof, together withy toe-calks, and I do not broadly claim rubber pads as my invention.

It is not necessary to carry the depression between the ribs c c2 entirely through the pad, as some of the features of advantage are present, even if it consists of a groove or recess, so long as strong calk-ribs are provided. Thus in Figs. 6, 7,8, and 9 a construction is shown in which'the parts c c2 consist of such ribs, the base part being imperforate, as shown in the sectional gures 8 and 9.

When the aperture D is carried entirely through the rubber, it acts to permit the air to pass through for the purpose of ventilating the under side of the hoof.

In order to increase the frictional grip of the pad or cushion upon the road-bed, I prefer to cover the under surface with a layer of reticulatedmaterial-such as strong canvaswhich increases'the hold of the hoof. The rear edge of the base/part c of the calk is curved, as shown in plan view, so as to provide two comparatively sharp backward-extending spurs or projections E E. These act to insure a iirm holding of the heel part of IOO the hoof, especially Vguarding against a backward slipping, this holding act-ion resulting from the backward curve of the edge and from having it and the edge c3 terminate in said spurs or projections.

In the pad shown in Figs. 10, ll, and 12 there are two apertures D and a supplemental projection c2.

That I claim is- 1. A rubber pad or cushion fora horseshoe, having the fiat thin base partB B B', extending around the foot and receiving the shoenails, the web c, proj eeting below the part B B and extending from the front part of the foot to a line behind the center and terminating in a concave rear edge in front of the heel, and the transverse ribs c' c2, extending down from the web c, and each being beveled or V'shaped in section and extending from side to side, with the ytransverse recesses between them, said ribs lying under the central part of the foot, substantially as set forth.

2. A rubber horseshoe-pad having the thin base part B, extending around the foot and adapted to receive the metal nails, base-web c, extending across the foot, with the series of transverse ribs c c2 running from side to side under the toe, and the through-apertures be tween said ribs, whereby Ventilation is provided under theibase-web c, the web terminating in the rear curved edge c8 at a distance in front of the heel ends B B', whereby the rear part of the foot is exposed, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
