`ELASTlC-HEEL HORSESHOE.

SPECIFICATION forming' pari; Of Letters Patent NO. 679,038, dated July 23, 1901.

' Application filed November 21, 1900. Serial No. 37,276. (No model.)

To' all whom t may concern:

Be it known that I, OTTO W. SIEBENHAAR, a citizen of the United States, residing at Ladoga, in the county of Fond du Lac and State of Wisconsin, have invented certain new and useful Improvements in Elastic-Heel Horseshoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert'ains to make and use the same.

In order to relieve shod animals, as horses, from the injury resulting from traveling over stony and other unyielding surfaces, the shoes in a number of instances are split and elastic pieces are fitted into the clefts or spaces. In a majority of cases these elastic pieces become unserviceable either by slipping or being crushed.

The present invention relates to horseshoes of the type aforesaid, and aims to increase their efficiency and to devise a construction which will insure the firm attachment of the elastic pieces under all conditions and prevent injury thereto by the pounding of the shoe upon stony and other unyielding surfaces.

With these ends in view the invention consists of the novel features, details of construction, and combination of the parts, which hereinafter will be more fully disclosed and claimed, and illustrated in the annexed drawings, in which- Figure l is a perspective view of a horseshoe embodying the invention as seen from the bottom or tread side. Fig. 2 is a bottom view of the heel portion looking toward the tread side. Fig. 3 is a heel view. Fig. 4 is a transverse section on the line a; of Fig. 2. Fig. 5 is a longitudinal section of the heel portion. Fig. 6 is a detail View of the inner sides of the parts bordering upon the cleft.

Corresponding and .like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In its general outline the horseshoe l is of ordinary formation, the heel portions being horizontally cleft and receiving elastic pieces 2 between the separated parts. The cleft members 3 and 4 may be separately formed and secured together at one end in any desired Way or they may be parts of an integral bar split and spread. Inasmuch as both heel portions of the horseshoe are similarly constructed, a detailed description of one only will be given.

The cleft member 3 is uppermost and the full width of the bar, with the exception of a slight outward taper, and its inner or lower side is chambered to form a longitudinal seat 5 to receive the upper portion of the elastic piece 2. This seat 5 or longitudinal depression is approximately half-round in transverse section and gradually flattens toward the toe of the horseshoe and deepens toward the heel and at the same time contracts in transverse extent, whereby outward displacement ofthe elastic piece 2 is prevented when clamped between the parts 3 and 4. The seat 5 gradually widens towardthe toe and at the same time decreases in depth conformable to the cleft formed between the parts 3 and 4,

and asa result a maximum amount of elastic material 2 is provided at the extremity of the heel, which is of great advantage in diminishing the shock upon the limb when the foot strikes a stone or other unyielding object or surface.

The cleft member 4 constitutes the heelcalk and may be one with the horseshoe or formed separate and welded or otherwise attached thereto. This member 4 gradually diminishes in Width toward the heel, so'as to come Within the side walls of the longitudinal seat or depression 5 of the member 3, and proportionately increases in thickness toward the toe to provide the necessary amount of metal to insure a stable structure. Alongitudinal channel 6 is formed in the inner or top side of the member 4, and its side walls are undercut, thereby giving to the channel in section a dovetail form, into which a portion of the elastic piece 2 is forced, thereby preventing any possible lateral play. thereof. This longitudinal seat 6 is deepened intermediate of its ends and gradually diminishes in depth toward its extremities. Hence the elastic piece 2 when clamped between the members 3 and 4 is prevented from longitudinal displacement. The marginal portions bordering upon the longitudinal seat 6 are flat and of sufficient extent to prevent their cutting into or otherwise injuring the elastic IOO piece 2, which would result if the faces 7 of the marginal part were narrovvr or sharp.

From the foregoing it will be understood that the elastic piece 2 is prevented from longitudinal and lateral displacement by means of the seats 5 and 6. The seat 5 contracting in width toward its rear end and the seat 6 deepening intermediate of its ends prevents the outward displacement of the elastic piece 2 when properly positioned. The side Walls of the seat 5 are of sufficient depth to preclude the possibility of lateral displacement of the elastic piece when the horseshoe is in condition for active service.

Having thus described the invention, what is claimed as new isl. In a horseshoe, cleft members constituting the heel portion, the upper cleft member being of maximum \vidthand provided in its inner or bottom side with a longitudinal chamber of approximately semicircular outline in cross-section and gradually contracting in transverse extent and increasing in depth from the toe toward the extremity of the heel, and the lower cleft member decreasing in Width and thicknesstoward the eX- tremity of the heel and formed in its top side with a longitudinal seat decreasing in depth toward the outer end of the heel and having iat faces at each side of said seat, andan crepes set forth.

2. In a horseshoe, cleft members forming the heel portion, the upper member being of maximum width and having a longitudinal chamber in its inner or lower side of semicircular form in cross section and gradually deepening and laterally7 contracting toward the extremity of the heel and flattening toward the toe, and the lower member gradually decreasing in thickness and width to- Ward the extremity of the heel and formed in its inner or top side with a longitudinal seat having its side walls undercut and gradually decreasing in depth from an intermediate point toward the ends of said member, and having flat marginal portions at the sides of the said longitudinal seat, and an elastic piece clamped between said cleft members and forced into the longitudinal seats thereof, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
