HORSESHOE-PAD.

SPECIFICATION forming part of Letters Patent No. 322,861, dated July 21, 1885.

Application filed April 4, 1885. (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 Suffolk 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 an improved pad or cushion to be employed in conjunction with a metallic horseshoe. It is interposed between the shoe and the forward part of the hoof, and at the same time is so constructed as to have a thickened part under the rear portion of the hoof below the frog.

Cushions or pads of various styles have been in use heretofore; but in one respect or another I have found that they have incident to them disadvantages which I have overcome.

Figure l is a bottom view of the cushion or pad detached. Fig. 2 is a side view showing the pad and shoe in place upon the hoof. Fig. 3 is a top view. Fig. 4 is a section on line as 00, Fig. 3. Fig. 5 is a bottom view of a modification. Fig. 6 is a section on line y y, Fig.5. Figs. 7, 8, 9 are respectively perspectives of modified forms.

In the drawings, A represents the forward part of the pad or cushion, this being more or less ring-like and comparativelythin and flat, there being an opening at the center, as shown at a.

I prefer to do away with the sheets or plates of one material or another which have been heretofore used, and which have extended over the entire under surface of the hoof, although some of the advantages of my device may be obtained if such a sheet or plate were employed.

By having the large central aperture, a, I provide sufficient circulation of air under the hoof, and prevent the heating and drawing which have been great objections incident to many of the pads heretofore in use.

By examining Fig. 3 it will be seen that the upper surface of the pad is flat, and therefore there can be a free circulation of air by the sides of the frog, the recesses or passage-ways permitting the air to pass to or from the aperture a.

The .part A-around the front of the aperture a is not formed with flanges, as has been customary in some cases heretofore-that is to say, the inner edge, a, of this ring-like part A does not extend down tothe bottom surface of the shoe, as will be clearly seen by examining Fig. 3-said edge a, upon the inside being substantially of the same width as the outer edge, a (see Figs. 7, 8, and 9,) although it need not be of exactly the same thickness, so long as it does not extend downward sufficiently far to press upon the ground inside of the shoe.

That portion of the pad or cushion which lies below the rear part of the hoof (inside of the rear ends of the shoe) is formed with the parts B B B, these being made integrally with V the forward thinnerpart, A. The part B lies under the frog, and the parts B B project forwardthey, in fact, providing the rear wall for the aperture (1.

Use has been heretofore made of a pad having a bulbous downwardly-extending projection beneath the frog, the ends or edges of which are rounded or sloped away from the central part, as shown, for instance, in Patent No. 179,952, to George W. Phillips; and I do not claim as my invention a pad constructed as therein shown and described. In the device alluded to the bulbous projection has not been extended downwardly so' as to lie below the shoe under normal circumstances.

My pad is intended to overcome objections which have been found incident to 'those of the character last referred to. I so construct the parts that the portion B B B shall not only receive the frog-pressure, but will also act as a stay or abutment to prevent either end of the shoe from being forced inward. There are squareor perpendicular walls 7), against which the ends of the shoe can be snugly fitted, said walls, together with horizontal walls b b, forming recesses by the side of the thicker part B B. These recesses permit the use either of a long shoe-that is to say, one having its ends extended to the rear edge of the heel, as shown in Fig. 2 at O-or the use of a shorter one, such shoes being used under some circumstances to increase the frogpressure.

Not only does the thickerpart of the pad said patent.

- edges of the metal shoe.

act as aforesaid in regard to the ends of the shoe, by reason of its being formed without rounded or sloping edges, but with square shoulders or ends fitting snugly the ends of the shoe; but, moreover, the shoe in turn insures that the pad shall not be displaced relatively to the shoe or hoof, there being a great tendency for such displacement to occur, owing to the fact that the thicker part of my pad is so shaped as to act as a calk wherewith the hoof can have a grip or secure hold.

It will be seen that the parts B B project forward, and as they extend downward considerably they act as calks to prevent a slipping forward, and the inner edges of these and the outer edges at the top of the walls or shoulders I) act as calks to prevent lateral slipping.

I am also aware of the fact that a pad has been. heretofore made having a part to lie between the shoe and the hoof, said part being divided at the front end and having an elongated part below the frog, and having a flange with a beveled inner wall extendingentirely around the central aperture, such pad being shown, for instance, in Patent N 0. 212,069, to W. A. Taylor; nor do I claim as my invention a pad constructed with the features therein shown; but I have found that when the article possesses the features of construction which I have devised and herein shown it accomplishes the ends at which I aim far more effectively than if use be made of the device shown in In the latter the surface of the frog-pad is one and the same with the surface of the aforesaid flange extending around the central aperture, and therefore it is impossible for the frog-pad proper to have the gripping action along its lower edges which is incident to mine by reason of the aforesaid downward and forward projecting calks B B, which, it will be seen, extend to points considerably below any of the rubber at the front part of the hoof. As a result, I attain a greater security of hold for the foot than if use be made of a narrow thin flange around the central aperture extending to the same depth as the frog-pad proper, which was incident to the article last above alluded to, as heretofore known.

Another important difference is that in these pads alluded to, as heretofore known, the purpose has been to have all of the downward pressure of the foot received upon rubber from toe to heel, the aforesaid, flange extending to the toe and also extending downward to points considerably below the shoe at the toe; hence all of the pressure of the foot is received by the rubber, the latter turning outward .and lying between the metal shoe and the ground, there resulting not only a less secure grip, but also a rapid cutting away of the rubber, it being constantly pressed and rubbed against the In my construction, on the contrary, I construct the rubber at the rear to extend considerably below any of the rubber at the forward part, so that the metal shoe itself can receive the pressure and the blows at the toe,while the rubber receives all of the pressure at the frog. I prefer to have an ordinary metal calk upon the shoe itself, as shown in Fig. 2, both it and the frog-pad at the rear extending downward sufficiently far to receive the pressure at the various points in the way described.

As shown, the concavity between the parts B B is curvilinear; but it will be readily understood that the same effect can be largely attained if it be otherwise shaped, and that some of the same advantages may be obtained even if the front edge of the thicker part be more nearly straight, so long as the surfaces and edges at that part are sufficiently well defined to insure a grip for the hoof. So, too, it is not absolutely essential that the front wall of the parts B B- should extend continuously to the top of the aperture a, although I prefer to have it so for convenience in manufacture.

To increase the capacity of the pad to act as calks, it may be recessed, as shown, at b 12 and the recesses may extend entirely to the walls b b, as shown in Figs. 5, 6, and 8; or ribs or projections may be left, as shown at b If in Figs. '1, 4, and 7.

One of the numerous other pads which have been heretofore known is shown in Patent N 0. 245,658, to Reidy, and one in Patent N 0. 226,848, to Grece; and I do not wish to be understood as claiming such articles as my invention; but the differences in construction and use between one like mine, upon the one hand, and either of those last above mentioned, on the other, I believe to be so apparent that it is not necessary to here set them forth in detail.

What I claim is 1. An elastic hoof pad or cushion having the thinner part A for the toe of the hoof, a central open aperture, a, the edge walla of which is constructed, substantially as set forth, to lie above the lower surface of the shoe, and

having the thicker part B B below the rear part of the hoof and between the rear ends of the shoe, the calks B B projectingforward from the part B and downward'below all of the forward or toe part of the rubber, and'the said thicker rear part, B B, extending out squarely to the inner edges of the shoe, substantially as set forth.

2. The combination, with the shoe, of the elastic hoof-pad having the thinner part 12 adapted to be secured to the hoof by the shoenails, and the thicker part B B, the side walls, I), of which fit squarely against the inner edges of the shoe, said part B B extending to a point below the rear ends of the shoe, and having at the front thereof vertical walls or edges extending down below the forward parts of the pad, the parts being constructed and arranged, substantially as set forth,whereby the metallic shoe at the front rests upon the ground, and the rubber at the rear rests upon the ground, substantially as set forth.

8. An elastic hoof pad or cushion having the thinner part b adapted to lie between the shoe In testimony whereof I affix rny signaturein and the hoof, and the thicker part to lie below presence of two witnesses. the frog and receive the pressure thereof, it
