SPECIFICATION forming part of Letters Patent No. 570,511, dated November 3, 1896.

Application filed February 24, 1896. Serial No. 580,310. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, WILLIAM SHAW, a citizen of the United States,residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Rasps; and I do hereby declare the following to be a full, clear, and eX- act 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 accompanying drawings, forming a part of this specification.

This invention relates to new and useful improvements in rasps and it consists in the construction and arrangement of parts, as hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide a rasp of simple construction, one that shall be cheap to manufacture, highly efficient for the purpose of dressing` the hoofs of animals preparatory to shoeing, and one wherein the blades may be removed and sharpened with great ease, accuracy, and rapidity and replaced in said rasp, rendering it as good as new, which object is attained by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a top plan of my improved rasp. Fig. 2 is a vertical section as taken on line 2 2 of Fig. 1. Fig. 3 is a perspective view of one of the plates with a shank thereon for accommodating the rear handle. Fig. l is a plan view of the plate used at the forward end of the rasp, also provided with a shank to be received by the forward handle. Figs. 5 and 6 are like views showing the plates that are employed in the rasp between the plates shown in Figs. 3 and 4. Fig. 7 is a perspective view of the washer used for separating the blades of the rasp, and Fig. Sis an elevation of one of the rods used in this rasp.

Referring to the letters of reference, A A designate rods, of any suitable gage and length, having at one end a head A" and at the other a threaded portion, and fitted thereto are suitable nuts a a.

B designates an angled plate, one side of said angle being beveled to form a cutting edge h and the other side of said angle being extended into a shank b for the accommodation of a handle B', said plate being provided with the perforatons d".

O designates a plate, designed to be used at the forward end of the rasp, having a shank c formed integral therewith, said shank adapted to be received by a suitable handle O', said plate O being provided with apertures c and having its lower edge beveled to form a cutting edge O.

D D designate plates or blades provided with apertures d Cl therethrough, the lower edges of said plates being beveled to form cutting edges, as shown at E E.

F, Fig. 7, designates a sleeve or washer, the length of which is about equal to the gage of the plates D, D', B, and O, said sleeve F being provided with a central opening f,extend ing centrally therethrough.

The apertures c (Z cl CZ and the opening f 7o through the sleeve F are all of the same diameter and adapted to snugly receive the rods A A.

The backs of the blades or plates D D are preferably depressed or hollowed in for the purpose of lightening their construction and improving the looks of the rasp when the parts are assembled, and the lower edges of said plates are provided with notches or indentations H to lighten said plates and to form cutting-corners, as shown in the several views at h.

In assembling the parts of the rasp the plate B, with its handle B', is taken and the rods A A passed through its apertures d until the heads on said rods come in contact with the back face of said plate, as shown in Fig. 2. Then a sleeve or washer F is placed over each of the threaded ends of said rods and moved along in the direction of the plate B until they come in contact therewith, when a plate, as D', is taken and the rod A passed through one of its apertures cl and the other rod passed through the other aperture, care being taken to so pass the rods through the apertures CZ cl of the plates D D5 that the bevels formed on the lower edges of said plates will always be on the side nearest the handle B, as clearly shown in Fig. 2. Then a sleeve F is passed along each rod until it comes in contact with said plate D', when a plate, as D, is passed along said rods in the IOO . manner set forth, and so on until the rasp is of the desired length. The second from the last plate to be placed on the rods is the one shown at C in Fig. 4, with its handle C thereon, then a sleeve F on each rod, and iinally a plate, as D. This plate C is set in from the end of the rasp, so that the lower end of the handle C Will not project over the end of the rasp, as will be understood. lVhen the plates B C D D and sleeves F have all been strung on the rods in the manner set forth, the nuts u. a are screwed onto the threaded ends of the rods A A', placing tensile strain on said rods and tightly compressing the plates and Washers, as Will be under stood. Should the ends of the rods project Very far through the nuts a CL, they may be clipped off to add to the appearance of the rasp.

It will be seen that a rasp made after the manner set forth and of the plates and washers described one is formed that may be used With great facility and efficiency for dressing the hoofs of horses preparatory to shoeing, for dressing the meeting ends of pulley-belts before splicing, for dressing the faces of Wood or other materials, and for other similar purposes.

A great advantage in using the plates described herein is that in sharpening they may be more easily and perfectly held While grinding, for With former rasps of this class, Where a single opening is made through the plates, it has been extremely difficult to so hold the plates that their edges may be perfectly ground, and it is evident that if the plates are not squarely ground when the plates are replaced in the rasp the rasping-surface of the tool Will be uneven. Consequently the utility of the article after once being sharpen ed by an inexperienced user will be greatly reduced; but with the apertures through the blades, as herein described, said blades are more easily held with the cutting edge thereof true to the grinder, or said rasp may be sharpened With the blades in place by using the ordinary iile.

I-Iaving thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An article of manufacture comprising the headed rods, the plates or blades, having cutting edges, mounted to snugly fit on said rods, the Washers between said plates and mounted on said rods, and the plates having the operating-handles mounted thereon all adapted to be closely united by means on the ends of said rods, When arranged as shown and described.

2. A rasp, comprising the headed rods, angled plate B, provided with a handle, the Washers, plate C, provided with a handle, the series of plates D and D strung upon said -headed rods, and means for securely holding the several plates upon the rods, all arranged substantially as shown.

In testimony whereof I hereunto set my hand this 15th day of February, 1896.

XVILLIAM SHAV.

In presence of A. BERGMANN, R. W. SIMPSON.
