Specification of Letters Patent.

Patented Feb. 18,1913.

Application filed February 21, 1911. Serial No. 611,098.

To all whom it may concern:

Be it known that I, Anrnon J. Hn'nsnr,

.a citizen of the United States, residin .at

Duluth, in the county of St. Louis and tate of Minnesota,-have invented certain new and useful Improvements in Shoe-Calks, of which the following is a specification, reference being had therein to the accompanying drawing. a

My invention relates-to improvements in shoe calks, and those used on base all shoes.

The object of my invent-ion is to provide a calk of the character described, which will enable the wearer to obtain a firm grip upon the ground same time to provide a are no angular corners, which minimizes the possibility of serious injury in the event of eing struck or stepped 'upon by one wearing said calk.

Another object of my invention is toprovide a more simple, cheap and efiective calk of this character having certain details of structure hereinafter fully described.

In the accompanying drawings--Figure '1 is a bottom plan view of a shoe showing my improved calk or cleat applied thereto. Fig. 2 is a side elevation of my im roved calk. Fig. 3 is an edge view partly roken away and looking in the direction of the arrow, Fig. 1. Fig. 4 is a side elevation of one of the plates showing the notch to receive the other plate and showing 5 is a side of the other plate notched to interlock with the plate shown in Fig. 4.

' Referring now to the calk in which there drawing, 1 represents the base-plate upon which are mounted my improved calks 2. The plate is secured to the shoe by means of screws passing through openings 3, in the usual manner. While I have shown three calks on the plate,

it will be understood that any number may be used and each calk may have a separate plate or base provided with openings whereby it is attached to the shoe.

The calk is preferably composed of two substantially semicircular-shaped projections 3' and 4, intersecting each other at their centers forming a cross composed of four radially arranged segmental members curving downwardly in the arc 'of a circle from the center to the plate 1, Iwhereby a calk is provided with continuous" curved edges which avoid any sharp corners and ertams particularly to to prevent slipping and at the.

the atthus avoid any liability of injury by. coming 1n contact therewith. The eripheral edges of the calk may be beveled as indicated at 5, to form a better surface to hold in the ground. These calks are preferably placed upon the sole of the shoe in such a manner that the calking surface of both semi-circular members extends. diagonally across the sole of the shoe, so that inthe event of striking an object aside blow'or direct forward or back blow, two quarters of the calking surface will be impinged in the impact and thus the thrust divided and the danger of abrasion minimized. When used in directcontactwith the earth while walking orrunning, the full benefit of the entire four quarters of the calking surface is 1ilitilized, forming an exceedingly eifective ca r.

From the foregoing it will be seen that each half of each semi-circular member forms a guard to the opposite semi-circular member, keeping it from coming in direct contact with an object, and it is. also evident that there may be a greater or less number of calking segments such as a three or five pointed cross forming the calk without departing from the invention.

In Figs. 4 and 5 I have shown a convenient manner of interlocking the two members comprising the calk, a portion of the center of each being cut away and designed to fit together one overthe other, each having projections 6 which pass through suitable openings in the plate 1 and are riveted thereto. The plate 3, as shown. is provided at the center with the notch 7, which extends about half the length of the plate and is provided at its lower edge with the lugs 6, which extend through the plate 1 and are turned over or riveted to secure it thereto. The plate 4 is likewise provided with the ears or lugs 6 and is provided in its lower edge with a notch 7 which interlocks with the notch 7 of the plate 3', whereby the upper and lower edges of the plates are flush with each other. This provides a more simple, cheap and effective manner of making the calks.

Having thus described my invention,

whatI claim and desire to secure by Letters intersecting each other and flush, said members so arranged upon the plate that they extend obliquely across the shoe when applied thereto. I 2. A device of the character described, comprising a plate, a calk secured thereto and formed of members having lower straight edges and curved flush intersecting edges, and lugs carried by the lower straight edges of said curved members for securing them to said plate.

.3. A device of the character described, comprising a plate, a calk formed of interlocking members having their outer edges flush, and lugs carried by the lower edges of said members and extending through openings in the plate for securing the members thereto.

4. A device of the character described,

comprising a plate, a calk formed of a memvided with a notch adapted to interlock with the notch of the first mentioned member, and said notch in the second member being of such a length that the outer edges of the members are flush, and'means for attaching said members to the plate.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses. ARTHUR J. HERSEY.
