UNITED STATES PATENT OFFICE,

JULIUS GAITZSOH, OF PAUNSDORF, NEAR LEIPZIG, GERMANY, ASSIGNOR TO KARL SCHIEGE,

OF PAUNSDORF, NEAR 'LEIPZIG, GERMANY.

SELF-SHARPENING GALK FOR HORSESHOES.

Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed May 25, 1906. Serial No. 318,751.

To all whom it may concern:

Be it known that I, JULIUS GAiTzsoH, a subject of the King of Saxony and German Emperor, residing at Paunsdorf, near Leipzig, in the Kingdom of Saxony and German Empire, have invented certain new and useful Improvements in Self-Sharpening Calks for Horseshoes, of which the following is a specifications The presentinvention refers to a horse shoe the toe and calks of which combine the advantage of the self sharpeningland of the elastic toes and calks, so that all jars on the frog are avoided and slipping equally prevented.

According to the present invention the parts of thetoes and calks subject to wear preserve along their whole height the same section, so that wide contact surfaces favor able to slipping are avoided, and at the same f such a horse shoe seen from below, Fig. 2 an elevation of the calk, in part section, Fig. 3 the same under load.

' The present invention essentially consists in the toe a, and the calks bof the horse shoe being fitted with volute springs f which are inserted in suitable bores d- (Figs. 2 and 3). The art of the spring f projecting beyond t e surface of the toe or calk respectively forms the Working surface proper, which according to the weight of the animal and the work to be done will enter more or less into the bore cZ, and by this means prevent hard jars from being transmitted to the frog. As in such springs the single twists lie closely together and the one twist will steady the other under lateral strain, and as the toe a or the calk -b or the stud grespectively will take up the said strain when the spring is compressed, it is entirely out of question that the spring could break or bend over, wherefore they can be made comparatively thin, and still be able to avoid slipping until they are entirely worn.

Having now described my invention, what I claim. and desire to secure by Letters Patent of the United States is:

A calk for horseshoes having a recessed body portion with attaching shank, a stud projecting within the recess, and a spiral
