T0 @ZZ wiz/0m, it 11a/ty concern:

Be it known that I, JOHN FRANCIS ROBIN- sON, a citizen of the United States, and a resident of Rockaway, in the county of Morris and State of New Jersey, have invented a new and Improved Horseshoe, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a construction of horseshoe of rubber having a metal skeleton core of horseshoe shape, the ends of said core being connected by a bar member, so as to strengthen the shoe at its heel-section, the said core being made of malleable or soft iron, so that after the rubber is cast upon the iron the shoe may be contracted or expanded to neatly iit the shape of the foot to which it is to be applied.

Another purpose of the invention is to provide guards for the nail-holes in the shoe and steel points for sundry of said guards, which points are exposed as the shoe wears and act in the capacity of calks.

A further purpose of the invention is to provide a simple, durable, and economic construction of a rubber horseshoe and means wherebyT a steel toe-calk can be used in connection therewith.

The invention consists in the novel construction and combination lof the several parts, as will be lhereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a bottom plan view of the complete shoe. Fig. 2 is a bottom plan view of the core or frame of the shoe. Fig. 3 is a side elevation of the said core or frame, parts being brokenaway. Fig. 4 is a longitudinal section through the shoe, the section being taken substantially on the line 4 4 of Fig. 1, and is also a section through a portion of the ,hoof to which the shoe is applied and Fig. 5

is a front elevation of theshoe and the portion of the hoof shown in Fig. 4.

The core or frame A, upon which the rubber O is to be cast or otherwise applied, is of skeleton formation and is made of malleable or soft iron. The frame A primarily consists of an outer segmental bar member 10 and an inner concentric bar member 11, the two main bar members 10 and 11 being connected by radial bars 12, integral with said members. A tie-bar 13 is transversely formed at the rear of the shoe, and this tie-bar. 13 is usually made iiat and comparatively thin and is provided with outwardly and forwardly extending side members 13a, which connect with the end portions of the connected bar members 10 and 11 at points be'- tween said bars, as is best shownin Fig. 2.

In connection with the body portion of. the frame or core, comprising the connected bars 10 and 11, a series of guards B is employed, an inner member being at each side, and a larger guard B is located at the toe portion of the frame, as is also best shown in Fig..2. The guards B are located at the inner edge of the outer body-bar 10 and comprise each. two suitably-spaced post-sections 14 and a connecting web-section 15, and both guards B and B extend downward from the under face of the body-frame.

The toe-guard B consists ofvposts 16, located one at each side of the front central portion of the body-bar 10, the said posts having V-shaped longitudinal grooves.` in their inner edges. The web-sections of thev guards B serve to protect nail-holes 18, suitably formed partially in the inner edge ofthe outer body member 10 of the frame and'fpartially in the web-sections of the guards.

A spur 19, preferably pointedat'the end,` extends down from the central connectingbar 18 and acts somewhat in the capacity of` a calk and likewise serves to give additional strength to the rubber at the toe portion of the shoe, where the rubber is subjectedto the most wear and strain.

Steel points 2O are located in sundry ofthe post-sections 14 of the guards B. Ordinarily the said posts 20 are locatedA inv alternate posts of the said guards B, as shown in Fig. 2; but each post may be providedwith a point, if so desired. As the shoe wears down the steel points, being harder thanthe other material of the shoe, will serve ascalks and tend to assist the animal in bad'weather.

The toe portion of the body-bar 10 ofthe frame or core A has a toe-clip 21 integral therewith, and when the rubber covering C is cast or other-Wise formed upon the frame or body A recesses 22 are produced in theside edges, where the nail-holes 18 occur in the frame or core, to permit a ready passage' of the nails through .said holes and into a hoof, as is shown in Fig. 3.

IIO

the shoe to be expanded or contracted by the i use of suitable tools, so as to shape the shoe to the form of the foot adapted to receive it. The tie-bar '13, passed through the heel portion of the rubber, as is shown in Fig. 4, reffectually strengthens the heel portion of the shoe and prevents it fromspreading, but

at the lsame time does not interfere with the 4contraction or expansion of the shoe for the p purpose stated.

In connection with the shoe a steel calk 17 is employed for the toe portion of the shoe, andthe ends 25 of this calk are V-shaped, so as to fit into 'the V-grooves of the post-sections '16 of the front guard B', as is illustrated in Fig. 1, and when the calk 17 is in place its upper surface rests against the bottom face of the frame and its under face is flush with the under faces of the posts 16 and is concealed by the covering C. -In forming the calk 17 its ends, in addition to being V- shaped in cross-section, are tapered downward and inward to a greater or less extent, as is shown in Fig. 5, and after the calk is in place the posts 16 are tapped at their side faces until the grooved portions of the posts closely hug'the V-shaped end portions of the calk, thus securely holding it in place, as is shown by dotted lines in Fig. 5.

It will be understood that the steel points 20 may be omitted, as they are especially de- A signed for use in the winter season, and the character of the .calk may be changed without departing from the spirit of the invention and that all of the calks may be of the same formation, if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In rubber horseshoes, a metallic skeleton frame of horseshoe shape, having nailholesA and guards therefor extending downwardly from the frame, and a rear tie-bar for strengthening the heel-section of the shoe, the tie-bar extending from side to side of the said frame.

' 2.' In rubber horseshoes, a metallic skeleton frame of horseshoe shape, having nailholes, and a rear tie-b ar for strengthening the heel-section of the shoe, the tie-bar extending from side to side of the frame, guide-posts ex.-

. connected with the end portions of the bodybars, and guards for nail-holes formed at the Ainner edge of 'the outer body-bar and extending downward therefrom.

4. In rubber horseshoes, a skeleton frame, constructed of malleable or soft iron and comprising outer and inner concentric body-bars, connecting-bars therefor, guards extending downward from the inner edge portion of the' outer body-bar, said guards comprising posts and webs connecting them, nail-holes bein(r formed opposite the webs of the guards, an a rear tie-bar connecting the end portions of the body-bars, the tie-bar having outwardlyinclined side sections.

5. In rubber horseshoes, a skeleton frame constructed of malleable or soft iron and comprising outer and inner concentric body-bars, connecting-bars therefor, guards extending downward from the inner edge portion of the outer body-bar, said guards com rising posts and webs connecting them, nai -holes being formed opposite the webs of the guards, a rear tie-bar connecting the end portions of the body-bars, the tie-bar having outwardly-inclined side sections, steel points for the posts of the said guards, a rubber covering for the said frame, and a pad-section for the upper face of the coverin of rubber, whichpad-section is integral wifoh the rear or heel portion of the slice but is unattached to the remaining portion of the shoe, for the purposes described.

6. A rubber horseshoe provided with metal posts extending down from its toe portion and a metal calk held between said posts.

` 7. In a rubber horseshoe, an inner skeleton frame or core, a rubber covering therefor, posts attached to the said frame at the toe portion, which posts have their opposin faces provided with V-grooves, and a meta calk fitted to the space between the said posts and having its end portions V-shaped to en- IIO ter the grooves of the posts, and'likewise downwardly and inwardly inclined, whereby when the calk is .in position between the posts the posts can be bent to locking engagement with the end portions of the calk, as specified.

In testimony whereof I have signed my.

name to this specification in the presence of two subscribing witnesses.
