To ctZZwzom/t may concern.` i s Be it known that l, FREDERICK CONRAD RoBiin'rsoN, a citizen or theUnited States,

and a resident ot Spokane, inthe county oi Spokane and State oi llfashington, have in-w vented certain new and useful Improvements in lflorseshoes, oit which the .following is a specification. 1 i

The present invention relates generally to horseshoes, and more particularly .to a

cushioned horseshoe oif composite structure.y

yThe object ot the invention is to provide a composite horseshoe of this character` in which the force oi impact and the tearing and major abrasive `iorces acting along' the shoe are received by a `metallicelement and `thereby prevented from breaking down the structure of the cushioning element, and in which the cushioning element ismost highly effective to absorb the stresses set up bv the forces acting upon the metallic clement and to `receive and absorb the forces not eiiective to deteriorate the cushioning element.

Another object of the invention is to pro vide a horseshoe ol this character of simple,

` durable and lightweight construction, reli-` able and efficient in practice, and easy and f inexpensive to manufacture. Other ob]ects and advantages residein the certain novel features of construction, ar-

rangement and coinbinationot parts which willbe hereinafter more fully described and particularly pointed out in the appended claims, reference being had to `the accouv panying drawings :forming part olf' this specification, and in whichp Figure 1 is an elevational view oi" tread surface of the shoe;

Referring tothe drawings, it will beseen that the'invention in all oic its embodiments f contemplatesa cushioning element indicated enerallyT at @anda metallic element indicated generally atM. n

in the einbod'ment of the invention shown in Figs. 1 to `6,thecushioning elementconiprises a bodjy'oi1 cushioning material, ,suchas vulcanized rubber, and includes a sheet-like portion 10 arranged to bear against the hoot oit the horse. The body also includes a sheet like portion which constitutes the inner portion oif the tread surface oil' the shoe, and an intermediate portion 1,2 integral with the between the portienslO and lland abut vthe portion 12 of the cushioning i element. The

plate 13 is vprovided. with an integra-l margip portions 10 and lland connecting the same. i

c canizedrubber oi? the body of the shoe tolie "ik nal flange 14; which extends entirely around 1 the outer marginal edge of the shoe and also around the heel of the shoe, as indicated at 15 in Figs. 1 and 2. The outer surface 14? oi' the flange is arranged` to `constitute the i outer inarginal portion of the tread` surface ot the shoe. i y The metallic plate 13 is `provided with'a `plurality7 ot hey openings' 16 `through which 'the vulcanized rubberextends to more positively associate the metallicand cushioning io o ' rubber arethus in general cao-planar and together' make up the tread surface of the-shoe.l

elements. The shoe is also provided with nail holes 17 which, as clearly shown in the drawings, extend through the flange 14 and theunderlying portion 1 of the rubber.

The surface ofthe rubberI constituting a portion oli'the tread surface is suitably formed to prevent slipping and lor this purpose is'provided with a plurality of vacuum or suction cups 18 and a plurality of serrations or similar devices 19.` rl-vhe planes of the highest points oif the anti-'slipping de- `-vices however, areall coincident'or below,v

preferably Ycia-incident, with thel tread surface"14aof the flange 14. The tread surface off the flange and the tread surface ofthe ln use, the tread suriace'l4a of the fia-nge 14 receives the impact Land the major forces incident to traction, as this surface 14a`extends entirely around the outer marginal 'ledge-of the shoe. T hestressesset up in thev flange 14 andthe metallic plate 13 of which it forms a parta'renot, however,com1nunicated'tov the hoof of the horse, but are ab sorbed by the cushioning material, mainly by the Aportion l()4 thereoi which underlies and is interposed between the flange 14 and i its plate 13, and the hoot.` Although the surface 14a o l' the metallic element receives the force of impact and `the major abrasive and other forces incident to traction, the tread surface of the portion 111 of the-vulcanized `rubber comes yinto action `almost simultaneously with or at least immediately y after the impact andisellective to enhance the traction and thereby prevent slipping and to receive and absorb the minor forces -actingupon the shoe. The portion 11 of the cushioning material is strengthened and supported inits function bythe metallic y "plate 13, and the cushioning action of the portion 11issupplementedby a similar actionof'the portions 10 and 12. i

y lt vis to be noted that although the metallic element is lirinly ei'nbedded in the vulcanized rubber constituting the body und is positively associated therewith by virtue ol 'the Yextension of the rubber through the key openings, the lflange 14, fin additiomis oliective at the ltoe and heelandpentirely around tfhe shoe to prevent disassociation of the rubf loer or of any portion thereof 'from the rne-` tallic element, functioning 1n this respect as alretaining ring to preventl tearing, split- *ting7 or similar :breakdown ofthe cushioning element which would otherwise be incident to traction. f

In the embodiment of the invention shown in'Figs. 7, -8 and 9, the cushioning element comprises a body of vulcanized rubber, and

includesa sheet-like portion 20 which may be'ar directly against the hoof or which may loe-provided with a covering 21 oi tough fabric. The body also includes a portion 22 ing action of'this embodiment of the-'invenwhich, as before, constitutes the inner portion of the tread surface of the shoe. A pad Jforms an integral part or' the cushioning element and extends entirely across-the'heel ei theshoe and centrallythereol, as'clearly shown in F 7., i i n A metallic element 24 is provided, and consists oi a plate of horseshoe form, embedded in the vulcanized rubber of the shoe and lies between #the portions 2O and 22 thereof.A The plate is provided with anintegral marginal `flange A25 .which extends entirely around the outer-'marginal'edge ofthe shoe, as shewn'in Fig. 'i'. rrlhe outersurface of the i'iange thus constitutes the outer inarginaly portion of the tread surface of the;

shoe. The metallic plate vis provided with a plurality 'of key openings v26threiigh which the vulcanized rubber oi the cushioning element extends to positively associate thejrnetallic and cushioning elements. fllhe -shoe'is also provided with nailiholes 2'? which extend through the flangel and thelunderlying portion of the cushioning element.

The surfaces of the rubber and ofthe metal constitute thetreachand are `suitably' vl'orinedtor prevent slipping, andthe highest points of the rubber and of the metallic elevment lie in the same plane for else the highest points o1 the surface ofthe rubber lie fbelow the plane of lthe highest points or' thesu-rtace shown in Figs. i', 8 land '9, but this ierniov my invention may be also embedded inshoes el?` the type shown in Figs. Ito! Gf. This torni oi ytheI invention includes av metallic element and :L cushion-lng element C, the cushioning element consisting oi vulcanized rubber and the meta-liu?y element being fonstjitu'ted oit any suitable metal. arly shown in the drawiiig, the cusl-iionifhg element is formed in general of two

sections

28 and 29, which-*are formed by splitting the tipping of the shoe, as at 30. lt isfobvious that the sections 2S andg29 lmay be liexed to varythe sizeof the vshoe `and that the metallic elements B1 'oi' various lsizes may, after the sections have been suitably'rleiied,' be slipped over thesectionsto embrace and retain the same in position. NVhen the shoe is then secured tothehoof of Athe horse by the nails` whichextend through Vthe-nail holes' of the metallic element and of the ,cushioning element the parts are positively maintained in assembled position, The cushion- A tion is in all respects similar tok that of the` `ifi-lirica e other embodiments oi' the invention, as hereinabove described. i

ln Figs. i3 to `19 inclusive Will be seen a nlodiiied torni oi' the invention in which `a horseshoe 32 is disclosed `made in substantially the conventional forni, but designed to receive the cushioning member 33, which may be made of rubber or other material,

said cushioning member havinga thick inner section and a comparatively thin flange or `outer section 35 adapted to lit llatvvise against the inner surface of the shoe 32. A pad 86 is also provided `formed with a heel 37 and a flat body 38 adaptedito lit beneath the cushioning member 33 and to entirely cover the horses hoof when in use. This construction maybe made completely of rubber, or it desired may be made from canvas or other stiiiening` material arranged therein, particularly in the heel member 37. After the parte have allbeen assembledas shown in lfigs.` 17 and 19` the ordinary horseshoe nails are forced through the usual` openings 39 through tlange 35 and part oi' the body 38 of padand vtroni thence into the horses hooi. The usual nails in this manner not only hold the completed shoe in place on the horses :toot but hold Athe* `various parts i'irmly together so they will act simultaneously and in a proper manner. ltivill be noted from Fig. 18 that part of the rubber cushion engages the,` ground, and the horseshoe S2 engages the ground adjacent the cushion While the horseshoe is continually cushioned by the flange 35 and part ot the pad l claim: y
