- HORSESHOE.

Specification of Letters Patent.

Patented May 25, 1915.

Application filed September 15, 1914. Serial No. 861,902.

To all whom it may concern:

Be it known that I, JAMES PULLAR, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented an Improvement in Horseshoes, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to horseshoes, and particularly to horseshoes of cast, malleable metal.

In order that the principle of the invention may be readily understood, I have disclosed a single embodiment thereof in the accompanying drawing, wherein Figure 1 is an underneath plan view of a horseshoe embodying my invention, and Fig. 2 is an end elevation thereof looking from the open end of the shoe.

Horseshoes as commonly constructed at the present time are hand or drop forged and are provided with toe calks which are separately constructed and welded on during the process of manufacture. This renders the shoe expensive to make and involves a number of manipulations.

An important object of my invention is to provide a shoe which can be readily formed at a single operation and which is so constructed that it affords great additional wear compared with those now upon the market.

Other objects of forth hereinafter.

Referring more particularly to the drawing. I have therein represented a horseshoe having a bodv 1, a toe calk 2 and heel calks 3, 4. In accordance with the preferred embodiment of my invention, the shoe including the body and the said toe and heel calks is cast of malleable metal, preferably semisteel or other durable metal. By casting the shoe, no hand labor thereon is necessary, and. the shoe is ready to be applied after the casting process. The shoes are made rights and lefts, the shoe herein shown being a left. It is preferably provided with a side clip 5 extending at its upper face on the outside and with a clip 6 at the toe. The said clips are preferably cast integral with the body 1.

Horseshoes as now constructed wear much more rapidly at the outside than at the inthe invention are set fore.

side. An important object of my invention is to overcome this defeat. This I accomplish by making the outside portion of the body 1 of the shoe heavier than the inside portion. In the figures, the outside portion is represented at A and the inside portion at B. Preferably these two portions are of equal thickness, but the portion A is substantially wider than the portion B throughout its entire extent; that is, from an axial line drawn through the toe of the shoe and passing between the heel calks equidistant therefrom. In order that the weight of the shoe may not be increased because of the wider construction of the outside portion A of the body, I preferably make the inside portion B somewhat narrower than hereto- Thus in efiect the substance that is taken from the inside portion B of the body is added to the outside portion A, and the entire weight of the body 1 remains substantially as before. If desired, however, the inside body portion B may be made of normal weight and width.

The toe calk 2 in the preferred embodiment of the invention is cast integrally with the body 1. As most clearly shown in Fig. 1, said toe calk is of gradually increasing width from the inside edge 7 to the inside edge 8. This gives greatly increased wear at the outside of the toe calk. Preferably, the toe calk 2' is curved in outline or of a form other than straight, so that all danger of catching the toe calk in railroad tracks, cross frogs, slots, etc., is eliminated. Heretofore so far as I am aware, the toe calks have been straight, and it is a very frequent cause of complaint that it catches in slots, thus loosening the shoe or drawing it from place, or even causing the horse to stumble and fall.

Although preferably to secure the best results, the toe calk is made of increasing width toward the outside and is also of curved contour, these features may be separately embodied, as each is advantageous. Moreover, vent the catching of the shoe in slots, as above setiforth.

Preferably the toe calk 2 is provided with a suitable number of tool steel pins 9- which afford additional wear, inasmuch as the wearing away of the softer material of the toe will leave the steel pins projecting far enough to prevent slipping. The reinboth features coiiperate to preforcing pins 9 are preferably placed in the sand of the mold, and the toe calk is cast about them.

The inside heel calk 3 is preferably of usual construction, excepting that it is provided with a reinforcing steel or hard metal pin 10 similar to the pins 9 of the toe calk 2. The outside heel calk 4 is, however, not only provided with a reinforcing pin 11 similar -to the pins 9 and 10, but it is made of considerably greater cross sectional area, as clearly indicated in Fig. 1, thereby affording largely increased wear at the outside of the shoe. It will thus be seen that the outside of the shoe including the outside portion of the toe calk 2 and the heel calk 4t is'so constructed as to afiord greatly increased wear.

Any suitable means may be provided to secure the shoe in position. Herein I have represented ordinary holes 12 through which the shoe may be nailed to the hoof.

I am aware that it has heretofore been proposed to make the outside half of a horseshoe of gradually increasing thickness toward the heel, and hence of greater thickness than the inside half of the shoe, as shown in the patent to McCeney, No. 199,302, January 15, 1878. This is objectionable in that the horse cannot travel with his feet level. The horseshoe constructed in accordance with my invention is provided with a body-1 which is of uniform thickness throughout. It is, however, of greater width on the outside than upon the inside, thus aflording greatly increased wear.

A shoe constructed in accordance with the foregoing disclosure wears evenly on the two sides, inasmuch as the greater pressure normally experienced at the outside of the shoe is counteracted by the greater surface throughout. Hence all twisting of the legs .and feet of the horse are prevented,

and he is enabled to travel with his feet perfectly level, thus insuring a'safe footing.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.

Claims:

1. In combination with a horseshoe having its sides of uneven weight, a toe calk symmetrically arranged at the front of the shoe and gradually tapering in thickness and evenly from the lighter tothe heavier end thereof.

2. In combination with a horseshoe having its sides of uneven weight, a toe calk symmetrically arranged at the front of the shoe and gradually tapering in thickness and evenly from the lighter to the heavier end thereof. the ends of said toe calk being abrupt to prevent shifting of the horseshoe.

3. A horse-shoe body composed of cast malleable metal having toe and heel calks integral therewith, the said body being of greater width at the outside than at the inside, but of substantially equal thickness throughout, whereby to add to the weight for the purpose of controlling the hoof action without'throwing the hoof out of level when brought into contact with the road bed, the said toe calk being of curved contour and having a fiat, broad tread sur face throughout, said toe calk being of gradually increasing width in cross section from its inside edge to its outside edge, whereby to add to the weight at the outside of the shoe, and thus to aid in controlling the hoof action.

In testimony whereof, I have signed my name to this specification inthe presence of two subscribing witnesses. 1
