- shoes, of which the following is a specification.

This invention relates to an improvement in horse shoes;

The primary object of the invention is to provide a horse shoe with a removable calk, in which the calk is supported on the shoe and effectually held against displacement without the use of bolts or other removable securing devices which have a tendency to work loose and which require considerable time in placing the call: on the shoe.

Another object of the invention is to so construct the securing means that the constant pounding of the calk will tend to tighten the securing means.

In the drawings: Figure 1 is a plan view of a horse shoe with the calks arranged thereon. Fig. 2 a side elevation. Fig. 3 a section on the line 33 of Fig. 1. Fig. 4. a detail view of the calk. Fig. 5 is a perspective view of a modified form of calk.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings, 10 designates the shoe which at its toe portion is provided with spaced ribs 11 and 12. Formed in the shoe at the sides of each rib and adjacent the base thereof are pairs of parallel extending grooves 11 and 12', each pair opening upon opposite sides of the shoe and each of said grooves having its wall adjacent the rib, undercut, as clearly shown in Fig. 2 of the drawings. The shoe is also provided at its heel portion with ribs 13 and 14, adjacent the base of each of which at the sides thereof are provided pairs of parallel extending grooves 18 and 14, each pair of which extends throughout the width of the shoe. The ribs are formed integral with the shoe, although the same could be secured to the shoe in any suitable manner. However, in practice, the construction illustrated has been found more effectual from the standpoint of manufacture as well as from the standpoint of efiiciency in operation. These ribs are substantially round in cross section,

the ribs 13 and 14 extendingentirely across the sides of the shoe. Disposed adjacent each rib and intermediate the ends of the ribs is a depression 15', the function of which will be hereinafter described.

The calks consist of'substantially rectangular blocks 16 which are each provided throughout their length with a longitudinally extending groove 17, the grooves being substantially circular in cross section and opening through the upper face of the block, whereby the blocks may be placed on the ribs carried by the shoe and defining on each side of the'block a longitudinally extending tongue, the inner wall of each of which is undercut as shown. In securing the blocks which constitute the calks to the shoe, they are first placed upon the ribs with their upper extremities engaging within the grooves formed in the shoe at the base of each rib, the grooves in the blocks being of substantially the same cross sectional design as the ribs. After the blocks have been assembled on the ribs with their end portions alining with the ends of the ribs, a portion of the block is forced into the depression 15 formed in the shoe. This is accomplished by means of a punch or any suitable tool, a portion of the metal of each of the blocks being securely lodged in the depression 15 as well as forced into binding contact with the rib, the punch directing the metal not only toward the shoe but toward the rib. It will be obvious that this arrangement effectually prevents the calk from spreading.

In order to facilitate the operation. of engaging a portion of the metal of each of the blocks within the adjacent depression 15, each of said blocks has formed in one side face thereof an inwardly extending slot arranged to come into alinement with the adjacent depression 15 when the block is positioned upon one of the ribs 11. As is best shown in Fig. 3 of the drawings, each of said slots terminates at its inner extremity in a shoulder which may be readily engaged by a punch or other tool to force the metal of the calk into locking engagement within the adjacent depression.

Particular attention is called to the fact that in use the constant pounding will tend to more securely force the projecting portion 18 of the call: in contactwith the shoe and bring the grooved portion of the shoe into binding engagement with the ribs. This binding action may be increased by forming the block which constitutes the calk, slightly wider adjacent its face which contacts with the ground, as illustrated in Fig. 5 of the drawings. In this figure, I have illustrated a modified form of my invention as showing a tapered block 19, this block constituting the calk. The block' is slotted at 20 in the same manner as described with reference to the preferred form of the invention, and in thus forming it wider at its outer face, an increased tread surface is provided.

The many advantages of a construction of this character will be clearly apparent as it will be noted that it provides an effectual calk attaching means which may be economically constructed and in which the calks may be quickly and securely attached to the shoe. lhe ribs 11 and 12 at the toe of the shoe are spaced, whereby the shoe may be sized without distorting the calks.

Having thus described the invention what is claimed as new is:

l. A horse shoe having a rib formed thereon and being provided with a depression adjacent said rib, and a calk mounted on the rib, said call: having an inwardly directed slot formed in one side face thereof in alinement with said depression and providing a horizontally arranged shoulder at the inner extremity of the slot whereby a tool may be i engaged with said shoulder to force the metal of the call: adjacent said depression into locking engagement within the depres sion.

2. A horse shoe including a body portion of substantially uniform thickness throughout its entire area, the said body portion at the toe having an upstanding rib formed thereon and having a slot formed in the adjacent face thereof upon each side of said rib, the said slots opening through the outer edge of the shoe and said shoe having a recess formed therein medially of said rib, and a calk arranged upon said rib and engaging within said slots, the said call: being disposed entirely within the lines of the body portion of the shoe and having a vertically disposed slot formed in one side face thereof terminating at its inner extremity in a horizontally arranged shoulder whereby a punch or other tool may be readily engaged with said shoulder to force the metal of the calk into locking engagement within the re cess formed in the shoe.

In testimony whereof I affix my signature in presence of two witnesses.
