HORSESHOE-CALK ATTACHMENT.

Specification of Letters Patent.

Patented Apr. 2, acre.

Application filedApril 16, 1917. Serial No. 162,504.

To all whom it may concern.

Be it known that I, Gnolion J. I-Innrnron, a citizen of the United States, residingat Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Horseshoe-Call: Attachments; and I do declare the following 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 certain new and useful improvements in calk attachments for horseshoes.

The primary object of the invention is to provide a calk attachment for horseshoes which can be easily and quickly applied to and removed from the horseshoes in connection with which it is to-be used.

Another object of the invention is to 1'0- videa calk attachment which is adjustable to fit the various sizes and shapes of horseshoes.

A further object of the invention is to pro vide an improved means for firmly clamping the attachment to the horseshoes.

A still further object ofthe invention is to provide a removable calk attachment which can be firmly attached to the bottom of the forward part of a horseshoe after the toe calk of the shoe has been entirely worn off, just as efiectively as it may be attached when the toe calk is in good condition.

A further object of the invention is to generally improve upon devices of this character by the. provision of a comparatively simple, strong, durableand inexpensive construction, one which will be efficientand'reliable in. operation, and well adapted to the purpose for which it is designed. WVith these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts which will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of the application and in which similar reference characters are used to designate like parts throughout theseveral views Figure l'is a'bottom plan view of a horseshoe, showing also in bottom plan view, a calk attachment constructed in accordance with this invention;

Fig. 2 is asectional view taken on the line 2-2 of Fig. l; l

Fig. 3 isa sectional view 33 of Fig. 1;

Fig. f is an elevation of the outer end of one of the calk-holding members; and,

*ig. 5 is a similar view of the inner side of the hooked clamp plate.

eferring more particularly to the drawings, the letter A designates a horseshoe across the toe of which the attachment is shown mounted. This attachment comprises a pair of calla-holding members 1 and 2, which are respectively provided with substantially countersunk openings 3 andl-l, and removable in these openings 3 and 4L are calks 5 and 6 respectively. It is to be understood that these calks may be of any desired form and the openings 3 and 4: may be changed in shape to accommodate anyform, but for the purpose of illustration, the calks are provided with straight sharpened edges.

The member 1 as shown more clearly in Fig. 2 of the drawings is provided at its outer end with a hooked portion 7 which engages around the outer edge of the shoe, and at the upper extremity of this hooked port-ion there are two points projecting inwardly and slightly upwardly, which points embed into the outer wall of the hoof near the top ofthe outer edge of the shoe. The inner end of the member 1 is provided with an upwardly projecting boss 8 having a screw-threaded aperture 9 extending therethrough. Arranged in the body portion of the member 1 adjacent the inner end of the aperture 9 is a recess 10 which receives the inner end of a screw 11 which projects from the inner end of the other calk-holding member 2. Thisscrew 11 forms a shank-like connection or means for adjustably connect ing the two calk-holding members together.

The calk-holding member 2 in addition to carrying the screw 11 at the inner end there of, has a screw 12 extending from its outer end. This screw 12' extends through an enlarged opening 13 in a clamp member 14. As shown, this clamp member 1a is provided with hook grips or points 15 at its upper extremity, projecting inwardly and slightly upwardly, which points embed into the wall ofthe hoof near the top of the outer edge of the shoe, and the inner surface of this member engages against the top of the outer edge of the shoe. A suitable nut16 forms the tightening means for holding the member 14 in clamped position, and if desired, a

taken onthe line lock washer 17 may be employed to prevent loosening of the nut after it has been tightened.

As clearly shown by Fig. 4: of the drawings, the outer end of the member 2 is provided with downwardly inclined ribs 18, these ribs 18 fitting into inclined recesses 20 arranged in the inner face or side of the clamp member 14, whereby when said clamp member is moved into tight frictional engagement with the member 2, the ribs and recesses cooperate and cause the clamp member 14: to be moved downwardly and inwardly, causing the hooks at the upper extremity of this member to embed firmly into the outer wall of the hoof, and the inner surface of the upper extremity of this member, just below the hooks or points, to engage against and over the top of the outer edge of the shoe and which obviously will cause the upper side of the member 2 to be tightly engaged with the lower side of the horseshoe, and to hold the calk 6 in place, this construction forming the subject-matter of U. S. Patent No. 1,038,883, granted to me on September 17, 1912.

As shown in Fig. 2 of the drawings, the claws of the hooked portion 7 of the member 1 are arranged at upward incline, and this is sufficient to similarly cause the upper face of the member 1 to be fitted snugly against the lower side of the horseshoe and to maintain the calk 5 in place.

The reference numeral 21 designates a substantially J-shaped spacing member, the shank portion of which is provided with an opening 22 into which the aforesaid screw 11 extends. The foot or base of this spacing member 21 is provided in its inner side with a recess 23 which receives the adjacent edge of the member 1, said recess being shaped to conform to the shape of this edge of the member 1. The outer face or ide of the foot or base of the spacing member 21 is provided with a recess 24: which receives the inner edge of the toe of the horseshoe.

By reason of the screw 11 connecting the two calk-holding members 1 and 2, these members areadjustably connected with each other so that the attachment may be adjusted to fit horseshoes of various widths. The ad justing is to be done before the device is applied to the shoe, as obviously the member 2 could not be turned so as to operate the screw 11 when it is applied.

If the device is to be attached to a shoe with a comparatively good toe calk, it will not slip forward any appreciable amount, as the two calk-holding members would be brought to bear with their forward sides against the toe-call: of the shoe, and it would be held stationary there. Owing to the peculiar shape of this device, the center being back of a line with its extremities at the points of their contact with the outer edges of the shoe, and the further fact that the outer edges of the shoe at these points of contact curve inwardly toward the front, without some brace forward and become loose. this and also to cause the device to pivot more freely so that in tightening it wil not bind,-but will take up. all slack or loose motion, the spacing member 21 is provided. This member 21 engages the inner edge of the toe of the horseshoe and prevents any forward movement of the entire attachment. By reason of the fact that the member 21 has a threaded connection with the screw 11, the former may be adjusted upon the latter to move it toward or. away from the central longitudinal axis of the shoe or to a place where it may engage any desired point on the inneredge of the shoe. Thus, the spacing member 21 is adjustable so that it may be effectively used with horseshoes of various shapes as well as sizes. It will be noted that in order to adjust this member, it is necessary to remove the device from the horseshoe and to unscrew the member 2, in view of the fact that one edge of the member 1 fits into a recess 23 in the inner side of the foot or base of the member 21 and prevents the latter from turning when the member 1 is in place.

From the foregoing, taken in connection with the accompanying drawings, it will be seen that the construction anc use of the invention will be readily understood.

As various changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of this invention, I do not wish to be limited to the precise construction herein shown and described.
