HORSESI-IOE.

Specification o'f Letters Patent.

Patented Aug. 20, 1912.

Application filed November 23, 1910i. Serial No. 593,763.

To all whom t may concern:

Be it known that I, JOHN P. KmFER, a citizen of the United States, residing at vWashington, District of Columbia, have invented certain new and useful Improvements in Horseshoes, of which the following is a specication.

This invention relates to horse-shoes, and hasvfor its object to provide an improved rough shod shoe` and to arrange for successively bringing into use new or unused callas or anti-slipping devices as the calks or devices which are in actual use become worn and useless.

It is a further object of the invention to so arrange the calks as to prevent lateral slipping of the shoe as well as endwise slip-i ping thereof.

With these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size and minor details may be made, within t-he scope of the claim, with-r out departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings,-Figure l is any inverted plan view of a shoe embodying the'features of the present invention. Fig. 2 is a longitudinal sectional view thereof, on line 2 2, Fig. l. Fig. 3 is a cross sectional view, on line 3 8, F ig. 1.

Like characters of reference indicate cor` responding parts in each of the several figures of the drawings.

The present embodiment of this invention includes a shoe body of any common or preferred shape, from which depends an annular fiange 2 extending throughout the body of the shoe and set inwardly from the outer periphery thereof, whereby an annular horizontal flange 3 is produced. In the horizontal flange 3 are nail holes 4 for use in fas-r tening the shoe to the hoof in the usual manner. v

Extending transversely across the bottom of the toe portion of the shoe within the tread flange 2 there is a series of calks which are successively designated 5, 5tl and 5b which decrease in height regularly from the front to the rear calli-` While only three such calks are shown, it will of course be understood that the series may consist of any number of callrs according 'to the size of the shoe or the requirements thereof.

Throughout the bottom of each side or leg of the shoe and within the tread flange 2, there are two'or more series ofcalks, one series being designated 6 and the other 7. The series 7 starts with a heel calk 7a, and extends forwardly, with the calks diminishing in height to the front terminal call( 7b, the same arrangement being true of the series 6, running from the calk 6a, located substantially midway between the heel and toe of the shoe, to the calk 6b. Each of the calks of the series (Sand 7 extends transversely of the shoe from the inner face of the tread flange 3 to the inner edge of the shoe and is beveled to a relatively sharp bottom edge. The end of each calk at the inneredge of the shoe is also beveled to a sharp edge 8 for a purpose as will be hereinafter explained. The toe calk 5 and the calks 7 a and 6a have their lower sharp edges in the same plane, projecting slightly below the tread flange,A whereby, in a new shoe, the tread 'is -upon the two heel calks 7a, the two intermediate calls 6a and the toe calk 5, whereby the shoe has an even tread and slipping is prevented. As these calks wear the next successive shorter calks come into use, and so on throughout the series of calks. It will of course be understood that the heel, toe and intermediate calks always rest upon the ground so as to have an even' tread, but if these become fiat by wear, it is the successive other calks which prevent kslipping of the shoe by reason of their 'sharp edges.

While the present shoe is of course useful on icy roadways, it is primarily intended to prevent slipping upon hard smooth roadways, particularly `wet vconcrete roadways.

What is claimed is A horse shoe having a depending tread flange located inwardly from the outer edge of the body of the shoe, said body being provided with nail holes out-side of the tread' flange, a series of transversely disposed toe caiks decreasing in depth toward the heel each calk'exten'ding from the inner side of of the Shoe, heel calks and intermediate the flange to the inner edge of the shoe. 10
