TOE CALK FOR HORSESI-IOES.

Application filed January 11, 1924. Serial No. 685,619.

To all whom it may concern:

Be it known that I, IVALTER FRANKLIN Prrornan, a citizen ofthe United States of America, and a resident of the city of Joliet, in the county of i/Vill, in the State of I11 inois, United States of America, have-invented certain new and useful Improvements in Toe Calks for Horseshoes, of which the following is the specification.

My invention relates to improvements in toe-calks for horseshoe with particular reference to calks of the removable type as opposed to the calk which is welded onto the shoe forming an integral part thereof, and the object of the invention is to provide an improved form of removable toe-calk which will be more rigidly secured upon the shoe than those formerly used and in which there will be no possibility of the calk turning or twisting out of its true position with respect to the shoe; a further object is to insure a more secure footing for the horse than hitherto; and a still further object is to provide a calk in which there will be less liability of the horse straining the tendons of its ankle as often happens with the type of removable calk now used.

My invention consists essentially of a removable toe-calk having a blade and a plurality of' shanks carried thereby and extending upwardly therefrom, the calk be ing mounted. upon the horseshoe by the engagement of the aforesaid shanks within orifices in the shoe, all as hereinafter more particularly described and illustrated in the accompanying drawings in which 2-- Fig. 1 is a plan view of a horseshoe having my invention applied thereto;

F i 2 is a front elevation of Fig. 1;

Fig. 3 is a front elevational view, to an enlarged scale, of one form in which my improved toe-calk may be made;

Fig. 4 is a plan view of Fig. 3;

Fig. 5 is a section on the line 5-5 of Fig. 3; and

Fig. 6 is a section taken similarly to Fig. 5 but showing a modified construction.

In the drawings like characters of reference indicate corresponding parts in the different views.

1 is an ordinary horseshoe which is pro vided with tapered orifices 2 at the front thereof.

3 indicates my improved toe-calk which comprises a blade 4 to which are secured the shanks 5.

The lower ends of these shanks are bifurcated at 6 to provide jaws adapted to engagetheblade.

In the embodiment of the invention illustrated in Figs. 3,4 and 5, theblade is pro PATENT OFF-ICE.

vided with elongated slots 7extending therer through, the purpose of which will presently appear. The upper ends of the shanks 5, are tapered at 8.- r

. Inthe modified form of the. invention shownin Fig.6 the slots.7 are'omitted and the blade is provided with a raised portion or bead 9.

The construction and operation of my invention is as follows.

Referring to the form of the invention illustrated in Fig. 3, 4, and 5, the shanks 5 are heated and while in this state are placed in position upon the blade and the lower bifurcated portion is pressed tightly together so as to firmly grip the blade, in which operation a portion of the metal of the shank is forced into the slot 7 (see at A in Fig. 5). This engagement of the metal of the shank within the slot 7 serves to positively secure the shank upon the blade and prevent axial movement of the shank.

The toe-calk is mounted upon the. shoe by simply inserting the shanks 8 within the orifices 2 and, since the shanks are tapered at 8 to correspond with the tapered orifices 2, a secure mounting is assured.

In the modified construction illustrated in Fig. 6, the shank is heated as above described and pressed into engagement with the blade in which operation the bead 9v of I V the blade embeds itself in the metal of the shank thus serving the same purpose as the engagement of the metal within the slots 7 as above described.

In order to facilitate the fitting of the shanks might be shifted longitudinally of the blade.

In the making of my toe-calks the shanks being of separate metal fro-m the blade may be made of softer steel. This is an important feature since when'the blade is made of suflicient hardness, if the shank is of the same material it -is so brittle that it is very liable to break.

These disadvantages are entirely v. over come in my construction since owing to the plurality of shanks carried by a single cal'k it is impossible for the call: to twister shift out of its proper position upon the shoe, and also since the calk comprises one long blade extending across the front of the shoe there is no possibility of the horses toot being thrown oi lth'e proper level and this great length of blade affords the horse a very secure footing.

While I have illustrated and described a speci fic "embodiment of my invention, it is to understood that this fillgll-t be considevabty altered as regards details Without departing from the spirit of the invention or the-scope ofthecla-im. For instance various other equivalent methods of attaching the calk tothe blade might be used. Also other methods of .pern'iitting alteration ofthe distance between the shanks. This could be obtained by simply bending the blades slightly when attaching -the call: upon the shoe. 7

hat I claim as my invention is:

A removable toe-call; for horseshoes, comprising a blade, a plurality of shanks, the lower ends of said shanks bifurcated and adapted to grip the upper edge of the blade, means coacting between the blade and shanks for preventing movement of the shanks axially, and rnean's permitting adjustment of the distance between the shanks.
