HOBSESHOE Specification of Letters Patent.

Application mm Ins-ch 26. mos. Serial No. 423,303.

To all whom it may concern:

Be it lmown that l, AUGUSTIIS F. PAL-'1: E

sex, a citizen of the United States, iesidiug in the borough of Manhattan, in the city and State of New York, have imcnted a certain new and useful Improvement in Horseshoes, of which the following a specification.

he improvement applies to that class in which the shoe can he provided temporarily with sharp corks or allowed to serve smooth according to the time of year or according to the temperature on special occasions I make two shoes adapted to match to each other and to the foot of the home, and

apply them one below the other, allowing the i one which lies nextto the hoof to remain an d only be changed when the growth of the hoof requires it, while the other is changed as oft-en as lequired. There have been many attempts to improve ho1se-shoes in this direction. I have devised important improvements in the means for attaining these conditions. I employ bolts in the provisions for attachment, and provide especially adapt-ed and peculiarly mounted not for receiving each.

One which no arts which cannot be readily renewed.

as following is a description ofwhat- I consider the best means of carrying outthe invention.

The accompanying drawings form a part i uality' of my improved horse shoe to of this specification.

I provide thine rectangular recesses b on the lower side of this lower shoe located one at the toe and the others at the heels. In F the center of each, a circular hole I) of sufficient size extends don-'nwm'dthrough the remaining thickness of the shoe. In use t-he recesses 5' each receives a not of steel.

D is the upper shoe, the removable shoe, I that which rests on the ground when in use. i I provide two of these, one having sharp corks D as shown, the other is similar except that the corks are smooth or omitted altogether. A description of the sharp corked shoe will serve for both.

The proper face of this shoe is provided with integral dowels D nrrnnged to match the recesses b in the adjacent shoe. These Elovide for the lateral strains. The holding ted bolts. Holes 11 in this up shoe coincide with the holes shoe,tlml5 is, the shoe B next. thehoof. The

importantfnnctions. Lnat ta'chingt e shoes together these bolts are turned by a screwo fitting insures against the loosemfilgyof thescrews whilein quantity and in hardness to properly hold and yet not such to offer an insurmountable difficulty when it is desired to remove the bolt. The heads of the bolts shouhl be soft as it may be found that the screw threaded ortions should be hard. I will describe the olts as made by case-hardening the scrmvthreads and shank and leaving the head soft. This mode of manufacture is attained by a practice long used to a limited extent in other arts making the bolt head at first too large and after earbonizing the surface of the whole, mechanically removing the surface of the head and afterwards heating the whole 1 and immersing in oil. As only the body with i i the screw-threads retains the carbonizedsurface only that portion is hardened.

It may sometimes be required to remove the nut Uwithout removing the shoe. I provide for this by the slot 0 in the nut and also bv the groove b in the bottom of' the recess b A suitable ointcd instrument as an awl can be inserts through the groove 1) and into the slot 0 of the nut C when a slight movement of the awl lever-wise, will displace the'nut by forcing it inward toward the ceni ter of the foot. This motion being repeated i the resistance of friction is overcome and the nut removed.

The first shoe B, that next the hoof may be of the ordinary breadth. lit may be grooved to favor the confining by nails and thicker at the heel than at the to all in the ordinary fashion lhc working shoe l), the upper shoe plate as they lie in being examined or re aired, is narrowed sufficiently on its outer sic e along a considerable portion of' its length, to allow the nail-heads to lie exterior thereto.

Modifications maybe made without departing from the principle or sacrificing the ad vantages of t ie invention. lhcrimay be Lused wit iout others.

more of the dowel-like projections 1). Such may be specially useful, formed one on each side of the center line at the front. Of course exactly corresponding recesses b must be provided to match. Parts can be I propose in the cheaper forms to omit much of the peculiari ties of the nuts and their recesses and to remove the shoe B when the nuts re uire attention. There may be more holes recesses b and bolts ID to hold the shoes together.

I. claim as my invention:

I. In a double horse-shoe, an upper shoe plate provided with a rectangular locking recess on the face to apply against the hoof, a nut locked therein, a securing bolt engaging such nut and a working shoe held and released by suchbolt the two shoes having also dowels and holes for resistin lateral strains, all combined as herein speei ed.

2. In a double l1orseshoe, an upper shoe plate provided with a rectangular locking re cess on the face to apply against the hoof, a nut locked therein, having a slot 0, a working shoe having a recess in the face farthest from the hoof adap'ted to receive a bolt head and a further recess in one side of such recess in combination with a bolt having a thin head of malleable material. adznted to be easily distorted to engage in such recess after the bolt has been tightened and with provisions for engaging such bolt with the upper shoe plate and for engaging the vrhole with'the hoof as herein specified.
