1 Claim.
The object of this invention is to provide a shoe having mounted therein one or more calks each provided with a base portion a part of which is of reduced cross section, whereby the metal of which the shoe is formed may be pressed into the portion of reduced cross section by the operation of suitable die mechanism, or any operation constituting the equivalent of a swaging operation, the calli being thereby rmly secured and held against displacement under practically all conditions arising through use.
A further object is to provide a calk having deflected end portions which may also include a base some part of which is of reduced cross section, whereby a similar swaging operation, as a final step in the operation of inserting the calk, will retain the latter, in the manner previously indicated.
A further object is to provide a clinching effect between the deflected ends of the calk and adjacent portions of the shoe, the deflected ends being partially embedded.
In the accompanying drawing,
Figure 1 is a view of the shoe in bottom plan;
Figure 2 constitutes a section on line 2-2 of Figure 1;
Figure 3 is a section on line 3-3 of Figure 1, the toe portion of the shoe and the toe calk being in elevation;
Figure 4 is a perspective View of the toe calk;
Figure 5 is a fragmentary View showing the manner of mounting a heel calk.
The shoe is to be manufactured of an alloy of aluminum, or other suitable material, and includes the toe portion 10 and the heel portions 11 and 12. The main side portions are provided with grooves 13 and. 14, adapted to receive the heads of the nails (not shown), and the Shanks of the nails will pass through holes or apertures 15.
An important feature is the construction and mounting of the toe calk 16, the latter being curved in conformity with the curvature of the toe part of the shoe, and having a bevelled portion 16'.
On the inner wall of the base portion of the calk a groove 1'7 is provided, and this may extend the full length of element 16, being adapted to have forced thereinto a portion of the metal of the shoe per se, as the final stage of the operation of forcing the calk home, under pressure of suitable die mechanism. All of the calks may be inserted or applied in one drop forging operation.
The ends of the toe calk are deflected to form lugs or ears 18, 18', and the inner Walls of the 1932, Serial No. 613,739
lugs are provided with continuations of the groove, or are cut away in such manner that a swaging operation may be effective also at these points.
The lugs 18, 18 are deflected toward each other, considered with reference to the chord of an arc dened by the main portion of the calk, and a type of clinching action is produced when the calk is in final position.
In Figure 5 I have illustrated a heel calk 20 provided with cut away portions 21 at the ends, and further provided with a groove 22 along the base of the calk, said portions 21, 22 being adapted to receive that portion of the metal displaced laterally as the result of a swaging operation or similar step following the insertion of the calk in the shoe. The calks being of hard steel or hard metal, and the shoe being formed of an alloy having a less degree of hardness, the calks may be, and are, inserted or applied without the necessity of forming sockets or recesses in the shoe. The operation, although inexpensive, is effective in a maximum degree, and uniformity in the product is assured.
The present invention relates to improvements in the construction patented by Earl H. Langlois, June 10, 1930, No. 1,763,433.
It will be apparent that I have provided a racing plate of extreme lightness, and of the requisite strength and durability, with a calk having great wearing qualities, with novel means for connecting the calk with the shoe. It has been demonstrated in actual use that horses equipped with the present form of shoe do not develop the usual leg and foot injuries resulting from the use of the conventional form of shoe. From the foregoing description, the advantages and novel features not directly mentioned will be apparent.
It is to be understood that changes may be made in the construction and in the arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
In a horseshoe, a main body portion, and a calk having a longitudinal groove in a side wall thereof, the calk having grooved end portions and the walls of all grooved portions merging to form a continuous groove, the metal of the body portion of the shoe extending into the longitudinal groove and into the grooves of the end portions, said grooved end portions of the calk being disposed angularly with reference to the major portion thereof, and having clinching relationship with reference to each other.
