Application filed December 14, 1914. Serial No. 877,145.

To all whom it may concern:

Be it known that I, GEORGE C. SIEBERT, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Horseslices; and I do hereby declare that the'following description of my said invention, taken in'connection with the accompanying sheet of drawing, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to improvements in horseshoes, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter iii-st fully set forth and described and then pointed out yinthe claims,

In the drawing already referred to, which serves to illustrate my said invention more fully, Figure 1 is a bottom plan of my improved shoe. By bottom plan, I refer to that face of the shoewhich contacts with the ground, or, in other words the tread. Fig. 2 is an elevation of the rear or heel end of the shoe in inverted position. Fig. 3 is a vertical section in line 8.-?) of Fig. 1. Fig. 4 is a like section in line le-4t of Fig. 1. Fig. 5 is a similar section inline 5-5 of Fig. 1.

Like parts are indicated by similar characters or symbols of reference ink all the figures of the drawing.

My invention has general reference to horseshoes of the bar type, and relates particularly to that class of bar shoes possessed of soft treads and connecting bars con-` structed of yyielding material, such las rubber and the like ;v and, the essence of my in vention resides in new and novel means for anchoring the said yielding bar to the underface of the body of the shoe at the rear ends thereof; to prevent the same from becoming loosened;, and correlated to these means are other means surrounding the greater portion of the yielding bar at both ends thereof, to eliminate the spreading tend-- ency of said bar when in use. The yieldable nature of rubber and rubber compounds is well known, and in the majority of shoes of the yielding bar, type, the bar entirely envelops the rear ends of the shoe, or is directly vulcanized to the under or upper face thereof, so that there is no resistance to the spreading tendency of the rubber composition while under the pressure to which it is 'subjected after the shoe is applied to a horses hoof. This constant pressure soon causes a flattening of the yielding bar and a vsegregation of the rubber mass, rendering the bar of no further value for the purpose for which it was intended; 'Le a cushionfor the horses hoof at the frog and heel thereof. In the practice of this present invention, however, the spreading, flattening, and segregation of the rubber bar is eliminated, as the ends of the bar, where practically the total weight is sustained, are entirely surrounded by calks depending from the under face of the body of the shoe, so that all pressure upon the bar results in an intensification of the rubber mass between the said calks, rather than a segregation thereof.

To better understand my invention, reference is now made to the drawing in which A indicates the horse shoe as a whole, which is of conventional conformation, being substantially of U-shape in plan with converging vrear ends AAQ which ends are generally termed the heel of the slice, while that portion A, located in the center of the U-shaped configuration is known as the toe thereof. Y

The base or body of the shoe is indicated at B and is of the aforesaid conformation with its rear converging portions B', B widened for a proper distance forward of the rear ends A and A, which rear ends are rounded as atk 10 and 10a. Around the inner outline of body B, beginning and ter# minating a short distance from the extremities of the widened portions B and B, there is formed integrally with the body B a continuous upstanding calk 12; vl; e., depending when the shoe is in use. And parallel to this calk, outwardly thereof and spaced therefrom and forming a channel 12a therebetweemis a like calk 1.3, which calk, however, merges into a heavy toe calk 13ZL at the toe portion A, of the shoe. Said calk 13 turns outwardly abruptly at Hand 14, then continues along the outer edges of the widenedv portions B and B, and partially around the rounded rear ends A and A thereof, as clearly seen in Fig. 1. It will thus be observed that the calks 12 and' 13 form confining receptacles or spaces 15 and 15a at the widened portions B and B for the reception of the ends 16 and 16aL of a transverse-rubber bar C connecting the ends of the shoe, the outer edgesV of said bar ends being embraced by the calk 13., as clearly seen in Figs.V 1 and 2,v and thev inner edges thereof embraced by the calk 12, the eX- treme ends of which calk are, however, bent inwardly aty 17, as seen in Fig. l, so as to form ay positive anchorage. r

Pierced from the body B, inthe portions B and B, and bent in a direction toward the tread of the shoe, are arcuate prongs 1'?a and 17E-which are anchored in the ends `16 and 16LA of the yielding bar C, these prongs providing additional 'anchorages, preventive of the loosening of said bar from the body of the shoe. C is concaved at C between the ends A andA whilel its forward edge thereof is conveXed as at C, the reason for which may now be explained as follows:

Horseshoes, when made in quantities in factories devoted to that class of goods are produced in definite sizes as to breadth and length, and are soldt-o jobbers, and thence to the horseshoersf. It isL seldom that the VVfeet, of a single animal are alike, and much less,

so. inthe case of a plurality of animals. Therefore means must be provided whereby a shoe of any particular size may be varied in width to fit a hoof of nominallyv that size. Sometimes the widened portions B and B and the rear ends A and A. must be made narrower in overall width and in other instances Vthe'width mustbe increased. As hereinbefore described, the yielding bar C is irremovably anchored at its respective ends 16and 16a in the spaces 15 and 15a, and the yielding material thereof therein confined; therefore, if it be necessary to widen a shoe, pressure by means of a light screw :jack is applied at the points 100 and 101 on the interior of the shoe. The yielding material, being securely confinedV at-its ends within the rear portions of the shoe, will .of necessity follow those portions thereof as they are widened out; wherefore the'necessary stretch of the yielding material of the bar is provided for by a flattening of the concave and convex curves C and C. If the requirements are such that the shoe needs to be narrowed, the body thereof is drawn together by suitable clamps applied at 102 and 103, in which casethe surplus material in the yielding lbar finds expression in an increase in the concavity and conveXity C and C of the bar C, in an evident manner.

The preferred process of afliXing the yielding bar C .to the body B may now be broadly disclosed as follows: Generally speaking, the body B is first placed in a mold having a cavity adapted to receive said n body. Said mold has a top half. containing a cavity of the shape of the vielding bar. Semi-plastic rubber or rubber compound is now placed in the spaces 15 and 15a by hand The rear edge of the bar x and suiiicient material supplied-to form the complete'bar C. The top half of the mold is then placed inposition; a strip of canvas 104 being placediadjacent theY body B, and Y the halves of the mold tightly bolted together, after which the mold and its con- Vtents is placed in a suitable vulcanizer to suitably vulcanize and cure the rubber'. This vdone, the shoe vis removed from the mold, when it will be found that the projections 17a and 17h, and the inwardly curved portion 17 of'calk 12 have been securely anchored within the bar C; thatA the said rubber compound is thoroughly secured in` the widened portions B and B, and that noV portion of the rubber compound has passed to the reverse sideof the shoe, this being prevented by the aforementioned canvas strip 104, and it kvmay now be added' that rthis strip is of the'same shape in plan as vthe shoe A. follows the outline of the calk 13.

but a distance spaced therefrom, equal to.

more or less, the width of the offsets 14 and I 14a. It is to beY understood, however, that these minute details of construction do not form a part of` my invention and may be varied at will. Through and around the body B, exteriorly of the calk 13, are produced a series of countersunkthrough apertures 106 for the reception of horseshoe nails (not shown) whereby the shoe is fastened to the animals hoof.

Driven into the channel 12a,eXtending from the widened portion B to the widened portion B, there is a U-shaped, rectangular section of yieldable material 110. This material is preferably a combination of a canvas and a rubber compound, vulcanized together in strips in 'a plane at right angles to the plane of the base or body B. Said material is generally produced' in aforesaid Y cross section in long lengths, and the length foreach shoe is cut therefrom. Being bendable in nature, the same-is shaped to the contour of the channel 12a and driven thereinto until the surface thereof is j slightly above the edge of the calks 12 and 13, and somewhat below the tread surface of the bar C. Y Y n While herein I have disclosed they preferred mode of practising my'invention, I

reserve the right to make such-changes and ioo alterations therein as may come within the f province of the skilled mechanic or permitted under the doctrine of equivalents.

Having thus fully described my invention I claim as new and desire to secure to myself by Letters Patent of the United States:

l. A horseshoe including a curved body possessed of inner and outer upstanding substantiallycontinuous calks, a filling mathereof, arcuate anchorages projecting from said body, in saidwidened portions of said body, and a yielding bar connecting `said rear ends, partially einbraced byl said calks,
