HORSESHOE.

Specification of Letters Patent.

Patented J1 uly 10, 1917.

Application filed June 19, 1916. Serial No. 104,380.

To all whom it may concern:

Be it known that I, Lon'rs F. COHEN, a citizen of the United States, residing at Pittsfield, in the county of Berkshire and .State of Massachusetts, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to improvements in horseshoes and particularly concerns the provision of detachable calks or contact members. I am aware that removable calks have been heretofore invented and exten sively used, and I do not therefore claim the invention thus broadly, but confine the present application to improvements therein, which are designed to overcome the serious objections found applicable to prior inventions of the same general description. Those types of calks provided with a stem adapted to be driven or screwed into a bore or threaded opening in the shoe usually become so firmly set by the introduction of dirt and the decomposition of the metal that great difiiculty is often experienced in removing them. This difliculty is particularly noticeable where the calk is worn well down upon the face of the shoe, so that no projecting remnant remains for the application of pincers or other implements for removing them. The present form of calk and securing means are designed to prevent the calk from becoming set and to facilitate its removal quickly at any time regardless of the amount of wear.

Referring to the accompanying drawings, in which a specific useful form of embodiment of my invention is illustrated, together with modifications thereof,

Figure 1 is a bottom plan view of a horseshoe provided with calks operatively mounted thereon; Fig. 2, a side elevation of the same; Fig. 3, a bottom view of one end of the shoe cut away and disclosing a plan view of the calk seat; Fig. 4, a side view of the calk; Fig. 5, a perspective rear view of the calk; Fig. 6, a cross-sectional view of the shoe through the center line of the calk; Fig. 7, a similar view of a shoe having a transverse opening therethrough to receive the calk and a modified form of screw for securing the calk in position; Fig. 8, a face view of the metal ring carried centrally on the calk; Figs. 9 and 10, end and side views, respectively, of the preferred form of screw employed for securing the calk in position on the shoe; Fig. 11, a face view of a spring washer disposed under the flanged head of the securing screw, and Figs. 12 and 13, end and side views, respectively, of a modified form of securing screw.

As shown, I provide a shoe 1, similar in outline and general formation to the ordinary horseshoe, and provided with a plurality of removable depending calks or contact members 2, 2, etc, adapted to prevent slipping and arranged under the toe and heels of the hoof. Each of the calks comprises a wedge-shaped tip 3 at its lower end, for contact with the ground, and a tapering squared shank 4- of less maximum width than the tip 3, for projection into suitable transverse recesses 5, 5, etc, of cor responding formation provided on the underside of the shoe. The body of the shoe is thickened about the recesses 5, to provide a seat 6 of annular formation surrounding the recesses and extending downward from the lower face of the shoe.

While I prefer to provide a closed recess in the shoe to receive the shank 4, to prevent dirt from working in around the calks, the recess 5 may be extended entirely through the shoe forming an opening 25, as illustrated in the modification of Fig. 7.

The calk 2 is formed round at its middle, intermediate the tip and shank 4, to provide a butt 7 adapted to bear upon the seat 6 within a slight recess 8 countersunk in the face thereof, and of less depth than the length of the butt 7, which is inclosed above by a removable metal ring 9 fitting closely thereon and adapted to prevent dirt and other substances from working into the re cess 5 around the shank 4, thereby tending to cause the same to become set and irremovable. Said ring 9 is preferably partly seat-- ed in a recess 10 of corresponding dimensions provided on the lower face of the seat 6 around the recess 8, and adapted to engage the projecting shoulders 11, 11, formed ondopposite sides of the tip 3 at its upper en Downward displacement of the calks 2 is prevented preferably by means of a screw 12, which is herein shown to extend through a threaded bore 13 provided laterally in the shoe, the inner end 1 1 of the screw being reduced and extending into an alined recess 15 provided in the shank of the calk. The shoe 1 is suitably recessed or countersunk at 16 to receive the flanged head 17 of the screw and a spring washer 18 which is carried on the screw under said flanged head and adapted to prevent displacement of the screw during use.

- In the modification shown in Fig. 7, a form of headless screw 22 is employed having a uniform diameter from end to end and projecting through a corresponding threaded bore 23 in the wall of the shoe and into a recess 24 arranged in alinement therewith provided in the shank of the calk. In both the preferred and modified forms of securing screws shown it is intended that no portion of the screw shall project beyond the side wall of the shoe.

The operation and application of my de vice may be readily understood from the foregoing description.

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

1. The combination, in a horseshoe having a transverse opening therein square in cross-section and being counter-bored around the margin of said opening, said opening being closed at its upper end; a removable contactmember having a calk at its lower end and a shank at its upper end square in cross-section and adapted to extend freely into said opening in the shoe, said shank being smaller in cross-section than said opening; a lateral extension-member provided on the contact-member intermediate the calk and the shank and adapted to seat in said counter-bore provided around the opening in the shoe and to close the opening; and adjustable securing means provided laterally on the shoe to prevent downward displacement of the contact-member.

2. A horseshoe having a body-portion of curved formation to extend around the margin of the hoof, said body-portion having a flattened lower face; a plurality of clown- Copies of this patent may be obtained for five cents each, by addressing the Washington, D. C.

wardly extending annular members provided on the lower face of the body-portion under the toe and heels of the hoof, said body-portion having recesses in its lower face opening into said annular members and extending well upward into but notthrough the body of the shoe; removable contact-members having their upper end smaller in crosssection than said recesses for projection freely into said recesses and having a lateral extension at their middle adapted to seat in said annular members for preventing upward displacement of the contact-members; an adjustable securing member provided laterally on the shoe and arranged wholly within the body of the shoe for preventing downward displacement of the contact-members.

3. A horseshoe having a squared opening on its lower face extending well upward into the body of the shoe; an annular depending member provided on the shoe around said opening and having a counter-bore around said opening and a separate counter-bore of larger dimensions and less depth around said first-mentioned counter-bore; a contact member having a squared shank extending freely into said opening in the shoe and having an annular shoulder around its middle to seat in said first-mentioned counter-bore; a removable ring carried on said contact-member and adapted to seat in said outer counter-bore for preventing dirt from working into said opening in the shoe; and adjustable securing means provided laterally Oh ment of the contact-member.

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