FRITZ. HERZOG, OF WASHINGTON, ADISTRICT OF COLUMBIA;

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 726,060, dated April 21, 1903.

Application filed February 7, 1902. Serial No. 93,065.- (Nomcdel.)

To a/ZZ whom t may concern:

Be it known that I, FRITZ HERZOG, a citizen of the United States of America, and a resident of -Washingtom District of Columbia,

have invented certain new and useful Im-k provements in Horseshoes, of which the following is a specification,. reference being had to the accompanying drawings, in which- Figure lis a perspective View of a shoe provided with my improved calks; Fig. 2, a similar view with the calks removed. Fig. 3 is a detail transverse section on the'line 3 3 of Fig. 4; Fig. 4, a section-al view on the line 4 4 of Fig. 3; Fig. 5, a detail cross-section taken through the forward or toe part of the shoeand Fig. 6 a det-ail perspective view of one of the calks. Y A l." l,

The object-of this invention is tolp'rovide a construction that will permit the shoeto be used with or without calks and the calksA to be readily attached or detached withoutV the intervention of skilled labor and Without removing the shoe from the auimals hoof, as

more fully hereinafter-set forth.

The shoe proper is constructed in any suitable mauner except as hereinafter described and is'provided with the usual holes for the passage of the fastening-nails. VThe threev calks are constructed alikeyeach consisting of a sharpened head portion-aand a shank portion b, formed integral therewith and projecting lateigally therefrom, lthis shank'por- I tion being tapered its full length in a direction away from the head portion Each shank is provided with a transverse hole c. To receive the toe-calk, the shoe is provided at the middle of its'bow Witha transverse tapering hole extending entirelythrough the bar of the v shoe from front to rear. Through this'hole the shankV of -the calk is rearwardly passed;R the shank fitting the hole snugly and project'- ing ashort distance from the rear Wallfof the shoe. Through the hole cin this rearwardlyextending end a nail or pin d is passed, which has its end or ends'suitably bent over to lock the calk in place.' To receive theheel-calks, each heel portion is provided with a socket extending into the shoe Yfrom the rear end thereof andatapered to snugly fit the shankV of the calk, and to lock the calk inv place a nail or pin d' is passed inwardly through the shoe from the side and suitably bent over on the inner wall of the shoe, the pin or nail vpassing through the hole c in the shank. To

compensate for any weakening that may result from making the sockets for the calks, 'the forward part and the rear vends of the shoe are somewhatrthickened, as shown, and to facilitate the removal of any matter that may pack into the heel-socketseslots or slits e are formed in the upper sides of-the respective heel portions, said slots extending from the rear ends of theshoe to approximately the inner ends of the sockets. When the shoe is put on the hoof in the usual way, its rear ends project far 4enouglrbeyondv the hoof Vto permit a nailorother tool tobe inserted into the '.sockets'through the slots, andthereby expel Y ,an-ydirt that may have lodged therein. These slots are important also in thatthey facilitate the formation of the sockets in the manufacture of the shoes, the slots permitting suitable dies to be used, over which the metal can be forged, thereby avoiding thenecessity of boring or drilling out the sockets. VFor this reasonA a slot or slit e is also formed in the shoe coincident with toe-calk socket and ex-v tending the full length thereof.

horseshoe Vconstructed as setforth possesses a number of important advantages.

It is obvious that a very great advantage lies in the fact that the treadf or Wearing face of the shoe is not mutilated and is entirely free of holes, lugs, dac., thereby specially adapting it for use as a calkless shoe, itwjbeing obvious that if the tread-facaof'the'shoe be provided with notches, holes,'or` lugs, or other fastening devices Ythese devices would soon become injuredpasvtredem-ption if the shoe .were usedfwithout the calks, thereby prevent- `ingthe calksbeing again replaced when the condition Aof the roads demands their use. This capability of using the shoe as a calkless shoe without injuring its capacity to receive and hold calks is very important from a practical standpoint in view of the fact that the frequent andsudden 'changes in the weather demand frequent and sudden changes in thershoes if injury totheho'rse is to be prevented and his usefulness inlallk-inds of weather is to be maintained. vAnother important advantage is that the calks may be readily attached and detached Without removing the shoe from the hoof and without ICO the employment of a skilled horseshoer. To attach the calks, it is simply necessary to clean out the sockets if any dirt be lodged therein, insert the shanks of the calks, and then look them in place with nails or pins, as described, and as these locking pins or nails are out of the way they are extremely unlikely to become injured suliiciently to either prematurely detach the calks or to prevent their ready removal when they are notneeded, their removal being accomplished when desired by simply straightening or cutting off the bent parts of the lock pins or nails.

Having thus fully described my invention, what I claim, and desire to obtain by Letters Patent, is-

A horseshoe adapted for use interchangeably as a calked shoe or a calkless shoe, having its tread-surface free of obstructions and mutilations and provided with sockets for removably holding calks, one of said sockets extending horizontally through the toe portion and the others extending horizontally and longitudinally into the ends of the heel portions of the shoe, calks having each an apertured-shank portion extending into one of said sockets, and a locking-pintor each calk, said locking-pin passing through the aperture in the shank and engaging the adjacent portion of the shoe at each side of the shank, each of said pins being removable and lying above the tread-surface of the shoe, as and for the purposes set forth.

In testimony whereof I hereunto aix my signature, in the presence of two witnesses, 35

this 7th day of February, 1902.

FRITZ HERZOG. Witnesses:

HERBERT C. EMERY, CHARLIE J. HERZOG.
