ROLLEY R. KENNEDY, OF MANSFIELD, OHIO.

HORSESI-IOE-GALK BEIVIOVER.

To all whom it may concern Be it known that I, RoLLnY R. KENNEDY, a citizen of the United States, residing at Mansfield, county of Richland, and State of Ohio, have invented certain new and useful Improvements in Horseshoe-Call: Removers, of which the following is a specification.

My invention relates to improvements in horseshoe calk removers, in which two members are pivotally connectedtogether in substantially the same manner as a pair of tongs.

It is well understood by those skilled in the art that by use the calks upon horseshoes become worn away and must be frequently renewed, either by sharpening the worn calks when made integral with the horseshoe or by removing the worn calks and inserting new ones,when the calks are detachably connected to the horseshoe. The usual method of connecting detachable horseshoe calks of various.

kinds is to provide screw threaded shanks which are inserted in screw threaded apertures formed in the horseshoe proper and from use these detachable calks become battered, worn away to a greater or less extent, and inactual use it frequently occurs that the calks are worn down quite close to the body of the shoe.

The object of the present invention is to provide means whereby the detachable calks can be easily removed, regardless of their condition. I attain this object by the construction illustrated in the accompanying drawing, although my invention may be embodied in a variety of other mechanical forms, the construction illustrated being chosen by way of example.

In the accompanying drawing: Figure 1 is a perspective view showing the device applied and in proper position to remove a calk. Fig. 2 is an edge view of the calk remover showing the same in closed position. Fig. 3 is a top view showing the parts in practically the same position as shown in Fig. 2. Fig. 4C is a view showing one form of a new calk properly connected to a horseshoe. Fig. v5 is a similar view showing a modified form of calk.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 and 2 represent the handles of the calk remover, which are pivotally connected together, the handle 1 being extended beyond its pivotal Specification of Letters Patent.

Serial No. 753,511.

' point and provided with the laterally directed jaw 3, which jaw is substantially of the form shown in Figs. 1' and 3. The handle 2 is extended beyond its pivotal point a short distance so that it is free to be swung back and forth with reference to the jaw 3. The handle 2 terminates in a aw 4: having a transverse end face of substantial width, which end face is beveled and is provided with a series of teeth 5. The aw 3 is beveled and provided with a series of teeth 6. The working toothed faces 5 and 6 of the respective jaws 4 and 8 confront one another and, by virtue of their opposite bevel, converge downwardly. The teeth of the faces 5 and 6 are oppositely directed and the faces themselves are laterally inclined relatively to one another, so as to have paths of movement which converge outwardly, as shown by the dotted line 8. In this way their grip upon the calk producesan initial pull or twist thereof, for a purpose which will presently appear. The purpose of beveling the working edges or face of the jaws is to provide sharp toothed edges upon the jaws, and by reason of the serrations, said dulled edges are toothed or serrated and are so formed for the purpose hereinafter described.

It will be understood that by beveling the edges of the jaws their contact edges can be brought into such positions that they will grip the exposed portion of the calk, regardless of its battered or worn condition. When the jaws are brought into position to grip a calk and a gripping action is effected as the handles 1 and 2 are brought toward each other the calks are first moved to a very slight extent longitudinally or a longitudinal strain is brought upon the calks.

It is well understood that after the calks 6 and 7 or any form of calk provided with a screw threaded shank has been connected to the horseshoe and the shoe placed in position for use, the shank of the calk become set, which setting or rigid attachment is brought about to a certain extent by corrosion and it frequently happens that it is very difficult to give to the calk the desired initial movement to break the rigid set of the shank. By forming the gripping jaws as above described the initial action of the jaws is to break the set of the shank, al though this initial movement is necessarily very slight, but by beveling the jaw 3 and the extreme end of the jaw 4, there is produced a suflicient degree of longitudinal pull upon the shank of the calk to loosen the set of the screw threads. It is Well understood that in use the calks become rusted and to a certain degree set in the screw threaded apertures formed in the body of the shoe, and it is the longitudinal pull upon the calk that has a tendency to break the set, after which the calk is more easily rotated and removed. For convenience one or both or" the handles 1 and 2 may be provided with wrench ends 9 which, in some instances, may be convenient for inserting new calks or for other purposes. 7

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is-

An implement for removing horseshoe calks comprising a pair of handles pivotally connected between their ends, one handle terminating in a laterally directed outer jaw having a toothed inner transverse face, the other handle terminating in an inner jaw having a toothed transverse end face of substantial width confronting the toothed face of said outer jaw, the said toothed faces being beveled and converging downwardly and also being inclined laterally relatively to one another, whereby their paths of movement converge outwardly.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
