Specification of Letters Patent.

Patented Feb. 29. fl $16.

Application filed. May 20, 1915. Serial No. 29,379.

To all whom it may concern:

Be it known that I, WILLIAM P. ROU- LAND, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Detachable Horseshce-Calksg and I do declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

This invention relates to improvements in horseshoes and more able calks therefor.

.The object of the invention is to provide simply constructed and readily applicable detachable heel and toe calks-which are designed for use on shoes having stub heel and toe calks to which these detachable calks are readily attached.

With this and other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as willbe' more fully described and claimed.

I In the accompanying drawings: Figure 1 represents a bottom plan'vlew of a horse-- shoe equipped with these improved calks; F ig 2 is a sideelevation thereof; Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1; Fig. 4 is a detail perspective view of the heel calks shown in Figs. 1 to 3. Fig. 5 is a similar view showing a blunt heel calk of similar construction.

In the embodiment illustrated a horseshoe 1 is shown of ordinary construction to which is integrally secured at the toe and heel thereof extension or stub calks- 2 and 3 respeotive ly. The stub calk or toe extension 2 comprises an approximately rectangular solid member having longitudinally spaced apertures as 4 for the passage of fastening bolts 5 for securing a removable toe calk 6 thereto. This calk 6 corresponds in length to the length of the stub calk 2 and is pro vided with a tapered or sharpened surface engaging portion 7. The incline of the front or outer face 8 of the calk 6 is very gradual or slow while the inner face 9 thereof is inclined abruptly and its inner or upper end is offset from the body portion of the calk by a shoulder 10 whereby the inner or up or portion of the calk is rendered much th-ic er than its lower portion. The thicker upper portion of this calk' '6 is bifurcated to proparticularly t6 detach-- the socket 11 and vide a longitudinally extending socket 11 here shown open at both ends and which is designed to receive the stub calk 2. The furcations or arms 11" are, of the same length and correspond in length to the width of the stub calk 2 so that when said calk 6 is applied the edges of these arms or furcations 11 which form the walls of the socket 11 will abut the lower face of the shoe 1 and thus be positioned to receive the ggeatest weight brought to bear upon the s co.

The armsll form the opposed walls, of

ing screw threaded apertures 12 positioned to register with the apertures t in the calk 2 when the parts are assembled to receive the fastening bolts 5 and whereby said detachable calk 6 is firmly and reliably clamped 1n operative position. I From the above description it will be obvious that this toe calk 6 may be readily applied or removed while the shoe is on the horses hoof by means of the securing bolts 5 which may be engaged or disengaged with very little trouble and in a very few minutes. Detachableheel calks 14 either sharpened as shown in Figs. 2 and-4 or blunt as shown in Fig. 5, are removably secured to the fixed stub'heel calks 3. Each calk 14 is formed integrally with the lower end of a U-sliaped attaching member 15, whose one arm 16 is of greater height than its other arm 18. The calks 3 are received snugly between the arms 16 and 18, the latter being disposed in contact with the front sides of said calks and rising into contact with the arms of the shoe 1, while said arms16 conness and bent forwardly at 17 around the rounded upper corners at the rear ends of said arms of the shoe. ,By this construction, all upward and downward movement of the members 15 and calks carried thereby is pre-' vented. However, the arms of said members are provided with registering apertures 19 which register with similar apertures in the stub calks 3 to receive bolts 20 which prevent lateral movement of the members 15 and their calks.

In the form shown in Figs. 1 to 4, the calks are substantially triangular with their wider portions or bases joined to the'members 15 and their vertexes 21 extending are provided with registerdownwardly to form surface engaging elements whereby the calks are reliably engaged with ice and snow to prevent slippingl v used they are designed merely to properly position the heel of theshoe in relation to the front or toe which is equipped with the toe calks 6 and these oe calks 6 are depended on for preventing slipping.

I claim as my invention: In combination with one arm of a horseshoe, said arm having its rear end bent downwardly to form an upright call: and having its upper rear edge rounded, a one piece U-shaped oalk attaching member snugly receiving said calk between its parallel arms, one arm of said member contacting with the gfront side of said calk and also with the under side of the arm of the shoe to prevent vertical movement of ing only toprevent 'lateralmovement of said attaching member, and a second calk formed integrally with and depending from the lower end of said member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM P. ROULAND.
