Be it known that I, DAVID JAFFRAY, of

' Chicago, in the county of Cool; and 'State of Illinois, have invented eertainnewand useful Improvements in Horseshoes; and I do hereby declare that thcfollowing is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in that class of ,horseshoes .consisting oi' a part which is attached permanently tothe horses foot,- and a second removable part which is attached to the permanent part in such manner that it may be readily removed for the purpose of repairing or rcplaci ng calks attached thereto, or for other purposesu The objects of this invention are to provide an improved means for detachably connecting the parts of atwopart horseshoe, and for securing calks in such shoes; and it consists in the matters hereinafter described, and pointed ont in the claims.

In the accompanying drawings, Figure lis a perspective view of a horses foot and a two-part shoe of 4a form proposed by my invention attached thereto. Fig. 2 is a similar view of the part of the shoe which is perina-- neatly attached to the foot. Fig. 3 is a perspective view of the removable part of the shoe detached. Fig. 4f is a plan view showing another form of the same. Fig. 5 is a fragmentary sectional view ofthe two parts lof the shoe, and of adjacent portions ot the hoof, taken upon line xm of Fig. 4. Figa 6 is a `similar sectional view taken upon lineje/ y of Fig. 4. Fig. 7 is a detail view, which will be hereinafter described.

A is the inner or stationary part of the shoe, which is attached by means of nails, in the usual manner, to the hoof, and is intended to be removed only at such times as it be comes necessary on account of the growth of the hoot.

B is the outer or removable partof the shoe, which is made ot' the same size as the part A, and preferably fiat upon its upper surface, so as to lit `open the corresponding :dat lower snrfacc of the part A., 'andis preferably provided With removable calks C, secured thereto in a manner hereinafter described.

As an improved means of removably securing the part B to the part A, the curved portion at the front or toc end of the bar, comprising the part A, is ont ofi' transversely, so

as to form a straight face, a., and the rea-r ends of its side portions are made slightly shorter than the corresponding portions of the part B, and are formed with transverse end faces, a', in alignment with each other and generally parallel with the face a. The opposite faces ca', above mentioned, are beveled downwardly and outwardly, as shown in Fig. 2, and the part B of the shoe is provided at its front and vso that when the two parts of the shoe are placed together bybeing slipped or moved sidewise, one upon the other, there will be no tendency of the plates to become loosened' by a slight relativelateral movement.

Instead of making the faces of the projections B and Bl and the faces of the part A engaged therewith inclined or beveled, las above described, the same result may obviously be effected by providing the parts with interlocking projections of other shape, as is, for instance, indicated in the detail View, Fig. 7, in which a part of the rear ends of the parts of the shoe are shown as provided with interlocking rectangular projections ci and 11".

The plates,when held together in the manner above descrbed,may be held from lateral movement by a pin, D, inserted through ap ertnres ai and Il in the plates A and B, respectively, or in any other well-known or dc sircdmanner.

As illustrated in Figs. l, 2, and 3 the parts of the shoe are held ltogether by the pin D only; butin the form oiI the shoe illustrated IOO portion, b5, surrounding the aperture B3.

in Fig. 4t the projections B and BI are provided with stops b4 to limit the relative lateral movement-of the plates in one direction, the pin D being depended on to hold the plates from movement in a direction away from the stops only. The pin D, as shown more clearly in Fig. 5, is preferably located at one side of the shoe, and adjacent to the outer edge of the bars or plates comprising the latter, a small notch', E, being preferablycut in the hoof at a point adjacent to the upper end of the pin, whereby a punch or other implement may be vapplied for driving out the pin. W'hen stops b4 are used,they are preferably placed upon the side of the shoe which is located at the inner side of the hoof, so that the part B of the shoe may be slipped in place from the outer side thereof; and the pin D is preferably located at the same or outer side, so as to be readily accessible to the operator. rIhe calks C are, as herein shown, provided with enlarged portions or heads c, and inserted in apertures B in the part B of the shoe, thc head c being countersunk or fitted in recesses in the shoe, so as to be flush with the upper surface thereof, and to rest against the lower surface of the part A when the parts of the shoe are placed together. The walls of the apertures B3 are preferably made parallel, as shown more clearly in Fig. 6,v and the portion of the calks located within the apertures of corresponding shape, the object of this construction being to prevent any slight end movement of the calks from loosenr ing them, as is liable to be the case when the body ofthe calks is tapered, as in a construction heretofore used in a two-part shoe. As illustrated in Figs. l, 3, and 6,three calks are used, the portion of the shoe adjacent to the toe-calli being shown as 11e-enforced by a raised In Fig. 4 thc part B is represented as being provided with apertures for four calks. Any desired number of calks may, however, be used, and they may be arranged in any desired or preferred manner. l

An important advantage in the construction in the means for connecting the two parts of the horseshoe above described is that the projections B and B2, being arranged transversely of th'e shoe, are in a position to more effectual] y resist the strains having the greatest tendency to separate the parts ofthe shoe.such strains being those produced by the pull or strain caused by-the efforts of the horse todraw the load and those caused by the'contact of the shoe with stones or the ground when the foot is thrown forward.

Another advantage derived from the construction set forth is that the calks are firmly and securely held iuplace, and may be quickly and readily removed and replaced or new ones inserted.

Other advantages arethat the parts being .exceedingly simple in/construction they may be easily manufactured to t to cach other, it being possible, on account of the simplicity of the structure in the lower and movable parts, to malte it of cast-steel,whereby :it will be much stron ger and Inoredurable than when forged of iron in the usual manner. By mal;-

ing the projections B' and B2, by which the upper and lower parts are connected, upon the lower part, the upper part or plate attached to the hoof is left perfectly plain and flat upon its lower side, so that when the lower or detachable part is removed the horse may rest upon the said upper part without injury thereto, and the said upper part `being comparatively lightr and thin, the horse is practically sh oeless when the said lower part is removed.

A great benefit may be obtained by removing the lower part when the horse becomes lame or is to stand some time without use, the foot, on account of the thinness of the plate, being permitted to rest upon the ground in the natural manner and with the frog in contact therewith.

Itis found advantageous to removethe lower part of the shoe, containing the calks, when the horse is to stand for some time, for the reason, also, that the liability ofthe horse to strike and injure himself with the calks is thereby avoided.

I 4am aware that two-part horseshoes have dovetailed projections upon one part which entercorrespondingly -shaped recesses in an-y other part. The appended claims are vnot therefore i intended to cover, broadly, such dovetailed connections; but my invention is limited to a construction in which one plate or part vcomposing the shoe is flat, andfis provided with transverse end faces constructed to interlock with transverseprojections upon the other part, as set forth in the following claims.

I claim as my invention l. The combination, with the stationary part A of a two-part horseshoe having transverse end faces, of a removable part, B, provided with projections B B2, having transverse inner faces constructed to interlock with the end faces of the part A, and means constructed to secure the parts A and B fromlateral movement, substantially as described.

2. The combination, with the parts A and B of a horseshoe provided, respectively, with transverse interlockingfaces, of stops b, constructed to hold the parts from movement in one direction, and means forholding the parts from movement in the opposite direction, substantially as described.

In testimony that I claim the foregoing as my invention IaffiX my signature in presence of two witnesses.

DAVID JAFFRAY.
