GEORGE BOOTH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN GRATERS.

Specification forming part of Letters Patent No. 138,122, dated April 22, 1873; application filed March 24, 1873.

- To all whom it may concern:

Be it known that I, GEORGE BOOTH, of the city and county of Philadelphia and State of Pennsylvania, have made a new and useful4 g section in the line y y.

This inventionis an improvement and modilication of that described in the patents of H. O. W'hite, of' April 25, 1871, and of Charles R. Pierce, August 8, 1871. y

Graters of this kind are made and sold in very large numbers, and it is therefore importantthat the manufacture be cheapened in every particular possible. The work must be done mostly by machinery to accomplish this. The demandsof the trade require that several sizes of graters be made.

By modifying the construction in the manner shown in the drawing all the various sizes required may be cut from a single piece of board, and thereby' both save in material and also in the work of fastenin g together the several parts. All the frame for a series of sizes is cut from a single board. In this a hole, h, is made for ahandle or to hang the grater up, and by simply fastening a cross-piece at the bottom the frame is completed, and only requires the grater-plate to be attached in the manner shown in the above-mentioned patents to complete the article.

The following description will enable any one skilled in the art to make and use this invention.

I take a board of the length and breadth of the longest-sized grater to be made and cutitin the form shown in plan in Fig. 1, so as to form two, three, Or more sizes of frames, A, B, C, &c. This manner of cutting forms the top and two side pieces. A bottom piece, H, is then fastened in by tacks, screws, or other means,

which completes the frame. The grater-plate D is then fastened to the frame by side strips a. a or by any other equivalent fastening.

Most of this work may be done by machinery, with very little loss of material, and the various sizes of graters required by the trade are provided in the relative proportions needed.

Having thus described `my invention, what I claim, and desire to secure by Letters Patent of the United States, is

The improved grater herein described, hav-4 ing a frame with the top and two sides cut out from a single piece of Wood, a bottom piece, and a grater-plate, all combined and arranged as set forth.

GEORGE BOOTH. Witnesses:

WM. B. HAZELL, Y JOHN F. CONWAY.
