GEORGE E. LINDBERG, OF DULUTH, MINNESOTA, ASSIGNOR TO DIAMOND CALK HORSE SHOE 00., 0F DULUTH, MINNESOTA, A CORPORATION OF MINNESOTA.

. HORSESHOE.

Specification of Letters Patent.

Patented Nov. 4, 1919.

Application filed February 19, 1915. Serial No. 9,272.

To all whom it may concern:

Be it known that I, GEORGE E. LINDBERG, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Horseshoes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

It is desirable in fitting shoes to horses that the calks of the shoe be set at different angles or different positions for different horses. This'is for the reason that with some horses the toe and heel calks, to best adapt the shoe to the horse, should be set at right angles to the body of the shoe, while with others, where the horse has a tendency to throw its feet outwardly, or interfere, i. a, strike the hoof of one foot against the opposite foot, it is desirable that the heel calks be set obliquely. Oftentimes these different tendencies of a'horse are not known at the time of fitting and nailing the shoe to its foot, and in other cases, the shoe may be adapted to a horse at the time it is fitted and nailed but the horse later acquires the habit of interfering or throwing its feet outwardly, which makes it necessary to refit the shoe or calks thereof. With the shoes now in use, it would be necessary to either remove the shoe and replace it with an entirely new one, or to remodel or recast the 01d shoe or calks thereof.

It is the object of my invention to provide a horseshoe and calks therefor so designed that the calks may be readily removed and set to or at different angles to fit a shoe of the proper size to different horses, or rather to adapt a shoe of the desired size to different horses.

The above and other features of novelty, advantages and capabilities will become apparent from a detailed description of the accompanying drawings in which I have illustrated two practical embodiments of the invention, but the constructions shown therein are to be considered as illustrative only and not as defining the limits of the invention.

Figure l is a bottom view of a horseshoe embodying one form of my invention showing the heel calks removed;

Figs. 2 and 3 are detailed views of the calks gland opening in the shoe shown in Fig. 1; an

'Figs. 4 and 5 are modifications of the same.

In the drawings, the shoe 10 illustrated is shown with the toe calks 11 in place while the heel calks are removed.

The shoe is provided with an opening for each calk, which openings are adapted to receive the shank 12 of the calk. In the form shown in Figs. 1, 2, and 3, the openings in the shoe are provided with an integral spline 13 adapted to fit into any one of the plurality of grooves 14 formed in the periphery of the shank of the calk. By providing the opening with a spline and the shank of the calks with a plurality of grooves as shown, the calks may be adjusted to different positions to properly lit and adapt: a shoe of the proper size to different horses.

In the modification shown in Figs. 4 and 5, this same result is accomplished by providing the opening in the shoe with a plurality of grooves 15 and the shank of the calk with a spline 16, which spline is adapted to fit into any one of said grooves when the calk is inserted in its position.

My invention is capable of other modifications than the two forms illustrated in the drawings and hereinbefore specially described, but I do not wish to be understood as limiting myself to the specific forms shown, except in those claims where these features are specified.

Having thus described my invention, what I claim is:

1. A horseshoe having an opening therein for receiving the shank of a calk, a spline formed in said opening, a calk provided with a shank adapted to fit into said opening and be removable therefrom, said shank having formed around its circumference a plurality of longitudinally extending grooves adapted to receive said spine, the number of said grooves being such as to adapt said calk to be readily adjusted to various angular positions with relation to said shoe.

2. A horseshoe having an opening therein for receiving the shank of a calk, a calk one of said interfitting parts having formed around its circumference a plurality of 1011- gitudinally extending grooves at intervals less than 180, and the other of said interfitting parts having formed thereon a spline, said grooves being adapted to receive said spline, the number of said grooves being such as to adapt said calk to be readily adjusted to various angular positions With relation to said shoe anddiffering one from 10 another by less than 90.

In Witness whereof, I hereunto subscribe my name .to this specification in the presence of two Witnesses. H

GEORGE E. LINDBERG. Witnesses:
