' 4 Claims. (01. 168-33) This invention relates'to horse snoes and more particularly to a shoe for race horses.'-' Shoes for race horses must be of; light weight andsince 1 race horses run upontracks which may be dry or muddy, it is necessary to provide a' horse with shoes suitable tothe condition of the track over which a race is to be run. s

. Therefore, one object of the invention is to provide a .shoe which is especially adapted for use by race horses since it, has a light body formed of aluminumand calks which are de-' tachably applied and maybe easily and quickly applied, according to the type of track over which the horses must run during a race.

Another object of the invention is to provide the body of the shoejwith inserts of hard metal in which sockets may be formed to receive threaded stems of calks. and without likelihood of splitting as would be the case if the calks were screwed into sockets formed directly in the body of an aluminum shoe.

Anotherobject ofthe invention is to provide -a. ca1k removably carried by an insert insuch -manner that it.will be prevented from I downwardly or having turning movement which I would loosen it. p v

In the accompanying drawing:

having the improved construction. Fig. 2 is a fragmentary'sectional view taken working Fig. 1 is a perspective view of a horse shoe along an enlarged scale, on the line Z-2 of Fig. 1..

Fig. 3 .is agroup view in perspective showing a calk for a muddy track removed. from the shoe.

Fig. 4. is a view similar to Fig. 3', showing a calk for a dry track.

i Fig. 5 is a fragmentary sectional view showing 7 the insert cast into the heel of a shoe;

The present horse shoe, indicatedin general by the numeral 1, is of the type used upon race horses and is formed'of aluminumor similar metal' so that it will be light i weight. v This shoe is provided with a toe calk 2 ofconventional 7 form and the heel portions are formed with enlargements 3 which project downwardly and have embedded therein inserts or blocks 4 which are formed of steel or other suitable hard metal. The inserts'are ofirusto conical shape, as shown in Figs. 2 and 4 of'thedrawing, and each is formed-at its outer'or lower end with a flat discmetrically opposite points with recesses 6 to reflat contacting engage ments 3 and serving to brace the inserts against turning movement case they should tend to loosen when the shoe is in use. A threaded socket 8 is formed in each insert axially thereof to receive the threaded stem of a calk.

,formed in the peripheral portion of the body of thecal k in diametrically opposed relation to each other to receive a wrenchfloy means of which the calk is screwed intoplace. About the stem of each calk the body is formed with a. circular recess 13 to receive a locking washer M of the split-washer type, and from an inspection of Fig. .2, it will be seen that when the calk is screwed tightly into place, the washer will be flattened and have biting engagement with the calk and the confronting lower face of the insert and re.- sist loosening of the calk.

The calk 9 carried by the heel at the outer sideof the shoe is provided with a spik l5 which extends outwardly or downwardlytherefrom and is tapered, toward its lower end, and, by referring to Figs. 1 and 2, it will be seen that when the calk applied to the shoe, turning thereof rwhile screwing it .into place is stopped with the calk disposed in the plane of the length of the shoe.

.cept for the wrench-receiving recesses or notches 1. V

.During fair weather when the track-is dry, calks without spikes are used .for both'heels of the shoe but when the track is muddy, spiked calk's maybe very easily and quickly substituted in lieu of the flat calks. In Fig. 1, a. single spiked calk has been shownin use and this calk is applied to the outer heel of the shoe so that the horse wearing the shoe will not be liable to cut one foot with the calk of the shoe worn on the other foot.

4 In-some cases, calks may beapplied to both heels of a shoe. It should also be noted that if desired, the insert may be formed asshown in Fig.

-5, wherein: the insert is solid,'the recesses 6 and thethreaded socket shown in Fig. 3, as well as:

in Fig. 4, being omitted. This form. of insert serves. as a permanent calkfor iast'tra'cks and shoes equipped with such calks or insertsare used upon horses not intended to run upon muddy tracks. Y r

Having thus described the invention, what is claimed is: v

1. A horse shoe having heel portions formed with depending enlargements, inserts of hard metal cast into the enlarged heel portions and each being of frusto conical shape and formed at its lower end with a flat disc-like head in flat face to' face engagement with the under face of the heel portion in which its frusto conical portion is embedded, said head being formed at its periphery with recesses for receiving portions of the enlargement and holding the insert against turning movement, a calk having a disc-like body, a threaded stem carried .by the body and screwed into the socket, a locking washer about the stem, the inner face of the body being formed, witha 'ing a disc-like head at its outer end in face to face 3; A horse shoe having heel portions, inserts of hard metal cast into the heel portions and held against outward movement, each insert havengagement with the under face of the heel portion in which the insert is embedded, each insert being formed with a threaded socket open at its lower end, calks, eachcalk having a disc-like body and a threaded stem extending centrally therefrom for engaging in the socket of the companion insert, and locking washers about the circular recess about the stem for receiving the locking washer, the outer face of the body being formed with wrench-receiving recesses, and a spike projecting from the outer face of the body in alinement with the stem.

2. A horse shoe having heel portions, inserts of hard metal cast into the heel portions and held against outward movement, each insert having a disc-like head at its outer end in face to face engagement with the underface of the heel portion in which the insert is mounted, each insert being formed with a threaded socket flpen at its lower end, and calks each having a disc-like body and a threaded portion for engaging in the socket of of hard metal stems for holding the calks against turning in a loosening directiomthe inner faces of the disclike about the stems for receiving the locking washers. 4. A' horse shoe having heel portions, inserts cast into the heel portions and held against outward movement, each insert having a disc-like head at itsouter end in face to face engagement withthe under face of the heel portion in which the insert is embedded, each insert being formed with a threaded socket open at its lower end, calks, each calk having a disc-like body and a threaded stem extending centrally therefrom for engaging in the socket of the com p'anion insert, and a spike extending outwardly from the disc-like body of one calk in alinement with the stem thereof.
