WILLIAM MERRICK, OF HARTFORD, CONNECTICUT.

HORSESHOE-CALK.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed December 26,1905. Serial No. 293,393.

To all whom it may concern.-

Be it known that I, VVILLIAM MERRIcK, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Horseshoe-Calk, of which the following is a specification.

My invention relates to the class of devices located on horse-shoes for the purpose of preventing slipping, and the object of my in vention is to provide a device of this class that shall be extremely strong and durable and that shall always present a sharpened surface until worn to the base of the calk; and a further object of the invention is to provide such a calk with means whereby the full benefits may always be derived therefrom. A form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation of -a shoe calk embodying my invention, and shown as attached to a shoe. Fig. 2 is a top or plan view of the same. Fig. 3 is a view in lengthwise central section through the calk. Fig. 4 is a detail view in central vertical section showing a modified form of calk. Fig. 5 a top or plan view of this latter form of ca c.

While it is not my intention to limit my invention to use in a removable calk, yet such a calk has been found by me to possess advantages when constructed in accordance with my invention, and I have therefore shown such a calk herein as one in connection with which to describe and illustrate my invention.

In the accompanying drawings the numeral 1 denotes the body of the calk which is preferably round in cross-section and slightly tapering from the base 2 to the tip. This base as herein shown is in the form of a flange projecting slightly beyond the walls of the body part of the calk. This flange may be flattened or ground off on opposite sides presenting flat surfaces 3 for the reception of a wrench by means of which the screw threaded shank 4 may be inserted in a threaded recess in the 'shoe in amanner common to removable calks of this general character.

An opening 5 is formed depthwise in the calk extending from the tip 6 to a point near the base 2. This opening conforms practically to the shape of the outer surface of the body part so that the body part 1 is ing from the extreme bottom of the opening.

5. The central opening 5, as shown, terminates in a solid bottom from which point the lateral opening extends. The bottom of the central opening forms a bottom that completely resists the pressure from dirt forced into the central opening, and as a result the dirt is forced out of the lateral opening 7, so that the central opening 5 can not become clogged to a degree sufficient to prevent the full sharpening effect from being obtained.

While I have shown, in the drawings herein, a device provided with a single lateral opening 7 as a device in which good results are obtained, yet I do not desire or intend to limit myself to acalk provided with a single opening.

In the device shown in Figs. 4 and 5 of the drawings I have illustrated two lateral openings 8 extending to the inner or central opening 9. These lateral openings are preferably formed slightly out of line with each other. These openings are formed in the body part in a manner to provide a web or ridge 10. This construction provides means whereby dirt or the like that is forced into the central opening is cut or broken up and the particles are then allowed to escape through the lateral openings.

l/Vhat I claim as my invention and desire to secure by Letters Patent is 1. A horse shoe provided with a calk having a depthwise opening terminating in a solid bottom and with a wearing surface extending completely about said opening, the wall constituting the wearing surface having a lateral opening extending from the bottom of the depthwise opening to the outer surface of the calk.

2. A removable calk for horse shoes including a body part having a depthwise opening terminating in a solid bottom and with a wearing surface extending completely about said depthwise opening, the wall forming this wearing surface having a lateral opening extending from the bottom of the depthwise opening to the outer surface of the calk.

3. A horse shoe having a calk with a depth- Wise opening terminating in a solid bottom and providing Walls of substantially uniform thickness from top to bottom extending completely around the depthwise opening, the said Walls having a lateral recess opening from the bottom of the depthwise recess to the outer surface of the oalk.

4. A removable calk for horse shoes in cluding a body part with means for attachment to the shoe, said body part having a depthwise opening terminating in a solid bottom With Walls extending completely about said opening and of substantially uniform thickness from top to bottom of the opening, said Walls having a lateral opening extending from the bottom of the central opening to the outer surface of the calk.

5. A calk for horse shoes including a body part having a depthwise opening terminating in a solid bottom and forming a Wearing surface extending completely about said depth- Wise opening, the Wall forming the Wearing surface having a plural number of lateral openings extending from the bottom of the depthwise opening to the outer surface of the ealk.

6. A calk for horse-shoes including a body part having a depthwise opening, and lateral openings extending from the depthWise opening to the outer surface of the calk and arranged With a Web between the ends of the lateral openings.

WILLIAM MERRICK.
