DETACHABLE CALK.

SPECIFICATION forming part of Letters Patent No. 601,260, dated March 29, 1898.

Application filed August 14, 1897 Be it known that I, LARs JoRGENsoN, of Brownsdale, in the county of Mower and State of Minnesota, have invented certain new and useful Improvements in Detachable Calks; and l do hereby declare the following to be a tion, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide an can be attached to any shoe Whatever its condition may be.

The objection to the detachable calks now on the market with which I am familiar is that they can be attached to shoes of only a particular form of construction and can only The aim of my invention is to provide a calk which can be readily and conveniently attached to a shoe and detached therefrom however much the shoe may be worn.

The invention will be readily understood by reference to the accompanying drawings, in which- Figure 1 represents a perspective view of a shoe With my improved heel and toe calks applied thereto. Fig. 2 is a vertical sectional View through one of the heel-calks. Fig. 3 is a vertical sectional view through the toe-calk. Fig. 4 is a detail perspective view of the parts of the heel-calk slightly separated one from the other. Fig. 5 is a similar view of the Like reference-numerals indicate like parts in the different views.

The shoe 1 is in all respects of the ordinary form and construction.

The heel-calk 2,` constructed according to my invention, is made up of a loop or band 3,adapted to embrace the end of the shoe,hav ing a threaded opening 4 extending through one side thereof. The calk proper, 5, is made with a sharp bearing-point, and the shank 6 thereof is threaded and adapted to be passed through the opening4 and engage the threads therein. Located within the loop or band 3 isa wear-plate 7, recessed, as shown at 8, along its opposite side edges, forming shoulders 9, which engage the outer edges of the loop or band 3. The said plate is adapted to Serial No. 648,284. (No model.)

move freely within the opening in the band 3 and is formed with bent angularlyarranged sharpened ends 10 10, which fit within corresponding recesses l1, iled or otherwise formed in the under surface of the shoe 1 just prior to the application of the calk. The heel-calk 2 ris secured upon the shoe 1 by inserting the end of the shoe through the opening in the loop or band 3, with the angularlyarranged bent ends of the wear-plate 7 fitting within the recesses 11 on the under side of said shoe. The shank of the calk proper is then inserted into the opening 4 and screwed tightly, forcing said wear-plate into close contact with the under side of the shoe. When it is in place, it is absolutely impossible for the calk to become detached, as outward movement of the wear-plate is prevented by its engagement with the side edges of the recesses 11, and the lateral or outward movement of theband or loop 3 is prevented by the engagement of the side edges thereof with the shoulders 9 on the wear-plate 7.

The toe-calk 12 is made up of two parts, which are connected to each other by screws 13 13. The inner part 14, which fits against the inner edge of the front portion of the shoe 1, is curved to conform to the shape thereof and is provided with a lip or iiange 15, which projects up over the top surface of said shoe. It also has a forwardly-projecting lug or ange 16 upon its under side, which bears against the under side of the shoe 1. The other part, 17, of said calk has a downwardly-projecting sharpened portion 18, constituting the engaging portion of the calk, and inwardly or rearwardly extending lips or ianges 19 19, which fit over and bear against the upper surface of the shoe 1. Extending along a line intermediate of the upper and lower edges of the part 17 is a ledge or shoulder 20, which lies directly opposite the forward end of the flange 16 and fits beneath the forward end of the shoe 1. The screws 13 extend through the ledge or shoulder 2O into the flange 16 on the under side of the part'14. When applied in the manner shown in Figs. 1 and 3 of the drawings, it is impossible for the calk to become detached without a loosening of the screws, and said calk may be applied to any shoe, whatever its condition may be, provided the distance between the ianges 15 and 16 on the part 14 and between the flanges 10 and 2O on the part 17 is equal to the thickness of the shoe or is made so by a file.

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

l. A heel-calli, comprising a loop or band adapted to fit over the rear end of a horseshoe, a call: proper having a threaded shank adapted to fit within a corresponding opening in said loop or band, and a wear-plate engaged by the end of said shank and adapted to be forced into contact with the under side of the shoe.

2. The combination with a horseshoe having recesses on its under side adjacent to its rear end, of a heel-call: therefor consisting of a band or loop adapted to embraee the rear end of said shoe, a call; proper having a threaded shank ii tting a corresponding opening in said band or loop, and a wear-plate having angularly-arranged bent ends adapted to lit within said recesses and having its side edges cut away forming shoulders which engage the outer edges of said band or loop, the

lower surface of said wear-plate being engaged by the end of said shank, substantially as and for the purpose described.

3. The combination with a horseshoe of ordinary construction, of a toe-calk therefor made up of two coaeting members, the inner member having forwardly-extending flanges at its upper and lower ends, adapted to fit respectively upon the upper and lower surfaces of said shoe, and the outer member having a downwaidly-extending sharpened portion constituting the engaging part of the calli, inwardly-extending flanges or lips at its upper end adapted to engage the upper surface of said shoe, and a ledge or shoulder intermediate of its upper and lower ends, and means for locking the two members together.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

LARS JORGENSON.
