Serial no. 822,420.

To (ZZZ whom it may concern Be it known that 1, JOHN H. Kinrrnn, a citizen of the United States, residing at Allentowi'i, in the county of Lehigh and State of Pennsylvania, have invented a new and useful. Toe-Calk, of which the following is a specification.

The present invention ap pertains to horseshoe (fillkS, and more particularly to toe calks.

It is the object ot the present invention to provide a toe callr for horseshoes, which shall. he comparatively simple, nou-encunibering and inexpensive in construction, which shall be of such construction, as to be readily applicable to and removable from the toe oi a horseshoe, which shall he capable of withstanding the hard usage and strains to which it is subjected. when in use, and which will otherwise be of advantage in its use.

With the t'mregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can he made within the scope of what is claimed, without departing from the spirit oi the invention.

The invention. has been illustrated in its preferred embodiment in the a 1conn anying drawing, wherein Figure l is a bottom view of a horseshoe having the improved toe calk applied there to. Fig. 2 is a sectio at view taken on the .line 22 of Fig. 1. Figs. 3 and 4- are sectional views taken on the lines and 4t-l-, respectively, of Fig. 2.

In the drawing, the numeral 1 designates an ordinary horseshoe, and the numeral. 2, designates generally, the improved toe calk.

The toe calk is constructed of hardened steel, or other suitable material, capable of withstanding wear and tear to a high degree. The toe call: 2 is disposed transversely across the bottom of the horseshoe, at the toe thereof, and the call: 2 is divided in termediate its ends by a diagonal cut 3, to provide two end sections t and 5. respectively. The adjacent or meeting ends ot the calk sections 4 and 5 are beveled or out chliquely, so as to overlap or tit snugly together, when the call: sections are alined,

the remote or outer ends oil? the ealh' sections being rounded or cut so as to conform to the outer edges oil. the horseshoe. The forward side ot the call: is flat, and perpendicular to th e horseshoe. while the rear side or face of the calk is pre ably inclined or beveled, from the free or lower edge of the talk, to pro vide a sharp anti-slipping edge.

To attach the calk sections l and 5 to the horseslme, the toe portion oi the horseshoe providml with laterally arranged or spaced threaded bores (S, which. are provided. at their lower ends with enlarged counterhores or sockets '1'. Each of the call: sections is provided at its upper edge or basal por' n, and. intermediate its ends, with a boss 8 adapted to fit snugly within. one oi? the eouuterljiores 7. the boss 8 being provided with a threaded projection 9 engageable in the corresponding bore (3 ot the horseshoe. Ordinarilv, when. the call: is in place, the bosses or studs 8 snugly engage the coimterbores 7, while the threaded projections or stenu; tl threadedly engage the bores (3, to maintain the call: sections firmly in position.

In order to clamp or secure the .tllk sections together, the adjacent ends of the call; sections are provided upon their rear side with a. boss 10, which is disposed adjacent the horseshoe 1, and which is divided by the cut 3, the inner end of the calk section 5 carrying the greater portion of the divided boss 10. he adjacent ends of the calk sections are also provided with a bore or opening 11 adjacent the horseshoe, or the basal portions oi? the call; sections, the bore 11 being coaxial with the boss 10. The forward end of the bore 11 extends through the inner end of the calk section t, while the rear end of the bore extends through the main portion of the boss 10 forming a portion of the inner end of the callt section It may thus be said that the bore or opening 11 passes through the overlapping or meeting end portions of the call: sections.

To clamp the adjacent ends of the call: sections firmly together, a bolt 12 is passed through the here or opening ll. the bolt being provided with an elongated head 15:3 at its forward end engaging the forward side of the calk section 4-, and overlapping the forward side oi the calk section the bolt head 13 resting snugly against the bottom of the horseshoe. A clamping or retaining nut 14: is threaded upon the rear end of the bolt 12, and a nut-locking washer l5 sandwiched or disposed between the nut 1d and the boss 10, the split washer and nut 14: seating against the boss 10 of the call; section 5, and slightly overlapping the rear face or side of that portion of the boss 10 carried by the inner end of the calk section Thus, when the nut 1 L is tightened, the adjacent ends of the calk sections will be tightly clamped together, in order that the call: sections will present a substantial uni tary call: construction.

In applying the toe call: to a horseshoe, after the threaded bores and counterbores 6 and 7, respectively, have been applied in the toe portion of the horseshoe, one of the calk sections st is threaded in engagement with the corresponding bore 6, and when the said call: section has been completely engaged to the horseshoe, the same is reversed for av quarter of a turn, so as to assume a longitudinal position. The other call: section is then threaded in engagement wit-h the corresponding bore 6 of the horseshoe. Then, when the last mentioned call: section approaches its normal or final position, both of the calk sections are turned so that the inner ends of the call: sections overlap or abut, when the call; sections are brought into alinement. It is to be noted that the screw threads of the bores 6 and threaded stems or shanks 9 are all in the same direction, whereby the calk sections will rotate in the same direction when being threaded into engagement with the horseshoe, and in order that the inner or beveled ends of the calk sections will swing together or meet properly. After the call: sections have thus been applied, the clamping bolt 12 is engaged through the bore 11. After the bolt has been inserted through the bore 11, the washer 15 and nut 1a are applied to the bolt, and when the nut is tightened the call: sections will be firmly clamped together. The toe call: thus presents a substantial antislipping device for the shoe.

The bosses S engaging the counterbores 7, are of advantage, inasmuch as it is possible. in practice. that the screw threads will not permit the call: sections to aline at the same moment that the call: sections seat against the horseshoe. which would necessitate a slight unscrewing of the calk sections, which would be objectionable. ith the provision of the bosses S and counterbores 7, however, the bosses S in engaging within the counterbores will take up the strains in an effective manner. notwithstanding the fact that the calk sections are slightly unscrewed when in normal position. Furthermore, the bosses in fitting snugly within. the counterbores 7 of the horseshoe, will also relieve the screw threads of considerable strain, as when the i call; is subjected to strains approximately parallel with the horseshoe.

The present call: may be readily applied to and removed from the horseshoe, as is ob vious from the foregoing, and is of advantage in other obvious respects, it being noted that the objects aimed at have been carried out satisfactorily. If desired, the toe calk may be pr vided with a blunt edge, instead of a sharp one.

Having thus described the invention, what is claimed as new is 1. A toe call; having a diagonal cut intermediate its ends dividing it into two sections, the call: sections having threaded projections at their basal port-ions and intermediate their ends, the meeting ends of the call: sections having a bore therethrough, one end of the bore extending through the corresponding end of one calk section, and the other end of the bore extending through the corresponding end of the other call: section. a bolt extending through the said bore and having a head at one end seating against one side of one call: section and overlapping the corresponding side of the other call: section, and a nut engaged to the other end of the bolt and seating against the other side of one call; section and overlapping the corresponding side of the other calk section.

2. A toe call: having its rear side inclined from the free edge of the calk, the rear side of the call; having boss at the basal portion of the calk, the call; and its boss, being divided on a diagonal line, intermediate its ends, to provide two alining sections, the call: sections having threaded projections at their basal portions and intermediate their ends, the adjacent ends of the call: sections having a bore therethrough coaxial with the said boss, the bore being disposed adjacent the basal portions of the call: sections, one end of the bore extending through the corresponding end of one call: section, and the other end of the bore extending through the corresponding end of the other calk section, a bolt fitting through the said bore and having an elongated head at its forward end seating against the forward side of one call: section and overlapping the forward side of the other callzsection. and a nut threaded upon the rear end of the bolt and seating against the boss sections of the two call; sections.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
