HORSE'SHOE.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed August 26, 1904. Serial No. 222,268.

To all whom, it may concern:

Be it known that I, J osnrn R. HOLLAND, a

citizen of the United States, residing at Binghamton, New York, have invented certain new and useful Improvements in Horseshoes,

I type in which the calks are made removable,

. in place.

and has for its object the production of a shoe of this type in which the calks may be easily secured and removed, but when once in place will be firmly held and will not become loose.

With this object in view my invention consists of the construction hereinafter described, and more particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a bottom plan view of a horseshoe embodying my invention. Fig. 2 is a detail view of one of the calks. Fig. 3 is a sectional view on the line a: a" of Fig. 1, showing the toe-calks Figs. 4, 5, and 6 show a modified form of fastening device. 7

In the figures, A indicates the horseshoe, which is of the same general construction as the shoes now in common use except that it is made without calks andat the points-where the calks are usually placed, is provided with threaded holes a.

The calks B, B, O, and D may be either square for ordinary use or they may be sharpened for icy weather, and are provided on the.

upper side with the threaded lugs b, which are adapted to enter the holes a of the shoe. The upper face of the calk is also provided with recesses c on opposite sides of the lug 7), into which the wedge (Z is driven to prevent the calks from turning and becoming loose. For the toe of the shoe I employ a double or two-piece calk, each piece of which is screwed separately to the body of the shoe. In order that these calks may be screwed into the shoe and have their ends closely abutting without the ends interfering and binding, I make the ends of the calks round, preferably making them to conform to the segment of a circle described from the center of the lug b.

uous calk.

As will be seen from the foregoing description, the toe-calks may be easily screwed into place, and when in the proper position theirends will abut, forming practically a contin- The wedge d being driven into the recess between the two pieces prevents theirturning. This wedge extends beyond the inner edge .of the shoe and is turned up and clenched.

By providing the calks with the wedge recesses in each end and making both sides of the calk alike it is possible to screw the calk much tighter into shoe, inasmuch as it is only necessary to give it a half of a revolution to bring it in a locking position, whereas a calk provided with a recess on one end only must be given a complete revolution before the wedge can be entered.

In Figs. 4, 5, and 6 I have shown a modified form of fastening device to be used with a single calk having the recesses formed in the opposite ends thereof. This fastening device consists of a washer L, preferably rectangular in shape, having a lug Z. opening in the washer is of such dimensions as to fit the rectangular projection m, formed on the calk by cutting out the recesses 0. When the calk has been screwed into place, the lug Z, which projects over the inner side of the shoe, is bent down, thereby locking washer and calk securely in place.

Having described my invention, what I claim is 1. In an article of the class describedthe combination with the horseshoe having open- The cle described from the center of the calk and r V means for securing the calk to the shoe, substantially as described.

In testimony whereof I afiix my signature in presence of two Witnesses.
