Specification of Letters Patent.

To cul, w/tom it may concern.-

G.Be it known that we, EDWARD IIERSON and SIMON L. DUNLAP, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Removable Oalks for Horseshoes, of which the following is a specification.

This invention relates to an improvement in horseshoe-calks; and the obj ect of the invention is to provide calks that can be easily placed into or removed from the shoe when the latter is attached to the horses hoof.

The object consists, further, in providing a calk for horseshoes which is so arranged that when it has become worn to a certain point the clampingmeans will drop out, and thus permit the calk to lose itself from the shoe. This last feature is one of the main objects of this invention, for the reason that it is more desirable to have a worn calk entirely removed from the shoe than to be continued in service and to interfere with the movement of the horse.

The accompanying drawings illustrate the invention, in which Figure l is a perspective view of a horseshoe, showing our improved calks in operating position. Fig. 2 is a longitudinal vertical sectional view of a calk, showing themanner in which the members comprising said calk are secured together. Fig. Sis a top or plan view of a calk with the shoe omitted. Fig. 4 is a perspective view of a calk having its sides sloped to an edge to insure a more perfect footing for a horse on slippery pavements during the winter.

In the drawings, l represents the body of the horseshoe, which is provided withv three elongated downward and inward sloping slots, which receivev the upper ends of the calks. The body of the calk comprises the two members 4 and 5, which are set together, and the intervening joining-line is cut ona diagonal plane, as shown. The upper ends of said members are cut on diagonal lines that taper toward each other, rand thus form Y a lock or key for the calk when the members 4 and 5 are nested together in operating position. The elongated slots in the shoe-body 1 are formed with tapering ends that correspond with the upper key ends of the members 4 and 5. In placing the calk into operating position the member 4 is first inserted into the elongated slot in the shoe-body, and after said member is seated the member 5 may readily be placed into position. The members 4 and 5 of the calk are provided with a longitudinal aperture 8, which registers when said mal when they have become irregular through wear, and an irregular-worn calk is considered more harmful than no calk at all. We have combined in this calk a feature which will permit the calk to free or lose itself from the shoe when the metal has worn down to the longitudinal aperture 8, thus permitting the split key 9 to drop out. With the use of this invention the life of the horseshoe is greatly prolonged and the condition of the horses hoofs preserved, for the reason that the shoes are removed only when it becomes necessary to re-dress the animals hoofs. The driver usually carries a number of the calks, so that when one becomes badly worn another can readily be substituted. In order to prevent any lateral movement between the members 4 and 5, we slightly channel the abutting end of the member 4, while the adjacent end of the member 5 is made to t said channel. (See Fig. 3.)

Fig. 5 is a perspective view of a calk the sides of which taper to a point, making it more desirable and efficient during the winter months, when ice and sleet are usually encountered. Otherwise the calk is made similar to the one disclosed in Figs. 2 and 3, which has previously been described.

I-Iaving thus fully described our said invention, what we desire to secure by Letters Patent of the United States isl. In a removable calk for horseshoes comprising a shoe rovided with slots the sides of which slant ownwardly and inwardly toward each other, a calk formed of a plurality of members and having its upper portion to register with the slot in the shoe, and locking means for securing the calk-forming members together. v

2. In a removable calk for horseshoes com- IOO prising a shoe provided with slots the sides of l ivo which slant downwardly and inwardly toward each other, a calk formed of a plurality of members and having its upper portion formed on downwardly and inwardly extending inclined planes to register and engage with the slot in the shoe, and having their abutting ends cut diagonally of the perpendicular, and locking means passing through the calli members to secure them together.

3. ln a removable calk Jfor horseshoes comprising a shoe provided with slots the sides of which slant downwardly and inwardly toward each other, a calli formed of a plurality of members and having its upper portion formed on downwardly and inwardly inclined planes to register and engage with the slot in the shoe, the abutting end of one of the members being channeled and the adjacent end of the other member formed to rit said channeled end, and locking means for securing the calli-forming members together.

In witness whereof we have hereunto set our hands and seals, at Indianapolis, Indiana, this 29th day of February', A. D. 1906.
