CHARLES W. ORANNELL, OF LEBANON, PENNSYLVANIA, ASSIGNOR OF ONE-THIRD TO CHARLES D. STEWARD AND TWO-THIRDS TO ELMER E. MCOURDY, OF LEBANON,

HORSE SHOE To all whom it may concern:

Be it known that T, CHARLES TV. CRAN- NELL, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in horse shoes.

The object of my invention is to provide a shoe in which the calks may be readily detached and new ones placed therefor, and in which the securing means is relieved of all the lateral strain of the calk.

Another object of my invention is to provide a frog-support for the shoe, whereby the plantar-border of the hoof is relieved of the entire weight of the horse, and thus allowing two-thirds of the weight to be on the plantar-border, and one-third on the frog which is the more normal and natural position of the hoof.

Another object of my invention is to provide a more simple, cheap and effective shoe to accomplish the above results.

In the accompanying drawings, Figure 1, is an inverted perspective view of my improved shoe showing the hoof in dotted lines. Fig. 2, is an enlarged perspective view of the heel portion of the shoe, showing the calk removed. Fig. 3, is a vertical sectional view taken on the line 00-00 of Fig. 1.

Referring now to the drawings, 1 represents my improved shoe which is made of an L-shaped'bar having the portion 2 resting against the hoof of the horse, while the portion 3 extends downwardly around the outer edge of the shoe. The portion 2, at the heel,

portions, is enlarged inwardly, as indicated at at and 5, and said enlarged portion having an offset, as indicated at 6, as will be now described. Resting upon the offset enlarged portions t and 5, is a steel plate 7 which is of a thickness equal to the offset, whereby the upper face of the plate 7 and the portion 2 are in the same plane or flush with each other, thus serving as unbroken frog supports. This plate, as before stated, is of steel, and is slightly concaved downwardly in order that the frog will have a springing action on the plate. The plate,

shown, is of approximately a wedge shape, having the slanting walls 8 and 9 which rest on the offset enlarged portions 4 and 5, and are secured thereto by rivets or screw-bolts 10. By this arrangement it will be seen that the frog supports some of the weight, and the plate is so positioned and shaped that one-third of the weight is supported by the frog and twothirds by the plantar-border, of the hoof which rests upon the shoe proper, and thus producing a shoe having a more natural means of supporting the weight of the animal.

The horizontal portion 2 of the shoe is provided on its lower face at the heel and toe portions with the bosses or sleeves 12. These bosses are provided with screw-threaded openings 13 therethrough and through the portion 2 of the shoe. Shoes of this character have to be made very thin, in order to be practical, and heretofore it has been diflicult to provide a screw-connection for holding the removable calks on the shoes. This boss, as shown, lengthens the threaded connection and also receives all the lateral strain of the calk, which I will now proceed to describe. The calks, the heel calks now being referred to, are formed of an elongated portion 14 which rests upon the portion 2 of the shoe, and is provided with openings 15 through which the sleeves or bosses pass, and whereby the lateral strain is on the bosses. The boss is of a length slightly less than the thickness ofthe portion 1 1 of the calk, and when the screw-bolts 17 are firmly screwed into the bosses the heads rest upon the member l t and hold it against outward movement. The screw-bolts are held in the boss against accidental unscrewing by a lost thread, as is readily understood.

The portion 1A is provided with a notch 18 inone edge, into which fits a lug 19 carried by the portion of the shoe. This lug as shown, is slightly longer than the thickness of the-portion 1 1 of the shoe, and extends slightly thereabove, and by driving the said lug inwardly, the portion 14 is driven against the flange 3 of the shoe, and also lightly against the bosses to prevent any movement whatever of the calk. The rear end of the portion 14 is provided with the calk proper 20, which is provided with a cut-away por tion 21 which receives the flange 3 of the shoe.

Thetoecalk 22 is of-the usual form, having the curved base portion 23 which is con nected to, the shoe in the same manner as the heel calks, but the lug 24 is made considerably wider so that it extends approximately over to the calk proper 25, and it being above the portion 23, of the calk, it can be driven over directly against the-call: proper andfirmly clamp the same against the flange of the shoe, and also tightening the connection with the boss.

The shoe is fastened to the hoof by nails, passing through the openings 26 in the usual manner. I

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

11 A horseshoe comprising body portion having adownwardly-extending flange at its outer edge, bosses carried by the body portion, removable calks resting against the flange and having openings receiving the bosses, means secured in the bosses for securing the call: on the shoe, and inwardly-extending ears carriedby the body portion and bearing against the inner edge of the calk.

2. A horse shoe comprising a body portion having a downwardly-extending flange at its'outer edge, bosses carried by the body portion; removable calks resting against the flange and having openings receiving the bosses, screw-bolts passingthrough the calks andentering said bosses, inwardly-extending ears carried by the body portion and bearing against the inner edge of the calk, and a plate secured to said ears and forming a frog support.

3'. A horseshoe comprising a body portion, bosses carried by the body portion, remov able calks having an enlarged base resting upon the body portion, having recesses to receive the bosses, screws passing through the calks and. entering the openings in the bosses, and a lug carried by the body portion and turned downwardly into a recess in the base of the calk.
