HoRsEsHoEING-RASP.

SPECJCFICATION forming part of' Letters Patent No. 644,020, dated February 20, 1900.

Application filed May 2,1899. Serial No. 715,271. (No model.)

To all whom it may concern,.-

Beit known that I, DANIEL LUDWIG, a subject of the Emperor of Germany, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in lvlorseshoeing-Rasps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such 'as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to facilitate the work of preparing the bottom of a horses hoof for the shoe and to do so without injury t0 the horse or hurting the animal, especially when the latter is the subject of a corn or such like excrescence or induration of the skin or flesh beneath the foot, and to secure other advantages and results, some of `which Inay be referred to hereinafter in connection with the description of the working parts.

The invention consists'in the improved rasp and in the combinations and arrangements of parts thereof, all substantiallyas will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the views, Figure l is a perspective View of my improvenient. Fig. 2 is a side view, partly in longitudinal section. Fig. 3 is a plan of aportion of the shank to which the handle is attached, and Fig. 4 is a perspective detail of a certain hooked projection for attaching the handle. Fig. 5 is a transverse sectional View taken on line so, Fig. 2.

In said drawings, a indicates the rasp-plate, having rasping-teeth such as are common in horseshoers rasps. Said plate is of oval shape in outline to enable it to be worked in the rounded concavity of the-hoof, the toothed face being convex both in longitudinal and transverse cross-section. The teeth project oppositely, those at therearprojecting backward and those at the front toward the front. The back of the plate is concave and at its front is provided with a short stud b and at its opposite end with a hooked projection c,

the hooking extension c' of whichis directed toward the front of the plate, as shown.

The handle d, by means of which the operator is enabled to properly use the rasp-plate upon the hoof, frog, duc., of the foot, comprises a curved bar or plate d', which more or less perfectly conforms to the concave back of the rasp-plate, so as to fit firmly against the same, and at its front is perforated, as at e, to receive the stud b, and at the opposite end is slotted, the slot f opening out through the rear of the'said curved plate to fit against the sides of the hook. The prongs h h, at opposite sides of the slot f, taper to help in guiding the plate beneath the hook, and the said plate is of a thickness to enter and iill the recess beneath the hook, so that the latter holds the plate rigidly in place at the rear. After having been slipped beneath the hook, as shown in Fig. 2, the front end is slipped upon the stud b, the latter entering the perforation e, so that there will be no'longitudinal movement of the plate and detachment from the hook.

To hold the plate d on the stud b, I em` ploy a removable handle 7c, the central bolt e of which is screwed into the threaded center hole m of said stud, the base of the body n' of the handle overlapping and pressing down upon the plate d' to lock it firmly in place upon the rasp-plate at the front. Between the handle lc and the hook-slot the plate d is provided with an integral handleshank o, which is first turned forward, as at handpiecep,the space between the handles being sufficient to permit the fingers to enter between. The toothed rasp-plate is then moved back and forth under pressure of both hands, and the convexity of the toothed surface and the oval outline of the plate all conduce to a TOO ing-plate having a stud and hook at the back, of a separable handle-plate d', perforated to receive the stud and slotted to receive the hook and having a handle-shank extending forward and curving backward therefrom and provided with a handpiece p, and a lockinghandle n, holding the said plate d', on said stud, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 30th day of March, '1809.

- DANIEL LUDVIG.
