WILLIAM J. HOOVER AND CHARLES T. KURTZ, OFCLEARFIELD, PENNSYLVANIA.

HORSESHOE.

To all whom it may concern:

Be it known that we, WILLIAM J. Hoovnn and CrIAnLns T. KURTZ, both of Clearfield, in the county of Olearfield and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

Our invention relates to horse-shoes, and more particularly to that class of horse-shoes having detachable calks.

An object of our invention is to provide a horse-shoe of the class specified comprising detachable calks that may be readily applied to and removed from the shoe proper.

A still further object of our invent-ion is to provide detachable calks of various kinds adapted for different conditions of service.

In the accompanying drawing, which illustrates applications of our invention, Figure 1 is an inverted perspective view of a horse-shoe embodying our invention; Fig. 2, a part sectional view and a part elevational view of the form of Fig. 1; Fig. 3, a view similar to Fig. 2 showing a modified form of our invention; Figs. 4, 5, 6 and 7, perspective views of calk-plates showing various forms of calks formed integral therewith; and Figs. 8 and 9, detail sectional views showing modified forms of heel calkplates and the manner of securing the same to the shoe.

Referring to the drawing, the horse-shoe proper, as illustrated and as preferred, comprises a body 1 formed with threaded toe perforations 2 and threaded heel perforations 3. In addition to the threaded perforations 2 and 3, the shoe at its toe portion is formed with corrugations 4.

5 designates a detachable toe calk-plate adapted to be applied to and removed from the toe of the shoe proper. As shown by the form of Fig. 1, the detachable calk-plate 5 has formed integral therewith a calk 6, a corrugated portion 7 and openings 8. When the detachable calk-plate 5 is applied to the shoe, the corrugated portion coincides with the corrugated portion of the shoe and the openings 8 of the calk-plate are adapted to register with the threaded perforations or openings 2 of the shoe. The calk-plate 5 may be secured to the shoe proper by any suitable means.

In the form of Fig. 1, we provide members 9 for securing the detachable calk-plate to the shoe. As illustrated, members 9 comprise a threaded shank 10 adapted to be Specification of Letters Patent.

inserted through the openings of the call:- plate and entered in the threaded perforat1ons 2 of the shoe, and each of the members 9 comprises a head 11 and a tapering body 12. The members 9, in addition to securing the plate 5 to the shoe proper, act as calks.

The heel calk-plates are designated by the numeral 18, and each has formed integral therewith a call: proper 14:. These heel call:- plates, in the form of Fig. 1, are designed to be secured to the shoe in substantially the same manner as the toe calk-plate 5, except that for the heel calk-plates we employ only a single member 9 for each of the said heel (talk-plates.

In the form of our invention as illustrated by Fig. 3, we have shown the toe ca-lk-plate 5*, formed with a-blunt or square contacting surface, and the front upper edge thereof with a toe piece 15. In this form of our invention, the shoe, as well as the toe call:- plate, are each formed with a slightly diiferent corrugated or notched portion 4? and 7 a respectively, from the form of Fig. 1, and in this form, we have shown a modified form of means for securing the toe and heel call:- plates to the body of the shoe. In the form of Fig. 3, in place of the securing members 9, we employ securing members 9 adapted to be passed through the openings of the calk-plates and engage the threaded perforations of the shoe.

In some instances we form the heel portions of the shoes with recesses 16 (see Fig. 8) and the heel calk-plates 13' with lugs 17 adapted to be entered in the recesses. If desired, however, the heel calk-plates designated by 13 (see Fig. 9) may be provided with recesses 16 and the heel portions of the shoe with lugs 17 Fig. 9 shows a modified form of securing means 9.

As illustrated by Figs. 4, 5, 6 and 7, the calks proper, which in all cases are formed integral with the calk-plates, may assume various forms and configurations adapted for different service conditions.

What we claim is:

In a horse-shoe, the combination with a shoe proper having notches formed on the outer surface. of the toe portion and threaded perforations in the toe portion at points on opposite sides of the center line of the shoe, of a curved detachable toe calk plate having a call: formed integral therewith and provided with openings registering with the toe perforations of the shoe and with notches coacting With the notches of the shoe, and separable calk-rnelnbers adapted to prevent sidewise slipping and for securing the calk-plate to the shoe, one of said separable calk-members being spaced away from an threaded toe perforation, a head adapted to bear against the calk-plate, and a tapering body portion projecting downwardly from 15 the head.

In testimony whereof We afiix our signatures 1n presence of two Witnesses.
