CASSIUS M. MAXSON, OF ALLENTOWVN, NEIV YORK.

NUTMEG-GR'ATER.

SPECIFICATION forming part of Letters Patent No. 435,235, dated August 26, 1890.

Application filed January 23, 1890. Serial No. 337,832. (No model.)

To all whom, it may concern.-

Be it known that I, OASSIUS M. MAXSON, of Allentown, in the county of Allegany and State of New York, have invented a new and Improved Nutmeg-Grater, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in' which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my new and improved nutmeg-grater. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a transverse sectional view on line 00 w of Fig. 2. Fig. 4 is a similar view on line y y of Fig. 2, and Fig. 5 is a perspective view of the rotating grating-disk.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

A represents a hollow body, preferably in cylindrical form, made of wood, metal, hard rubber, glass, porcelain, or other suitable material. One end is closed by a cap .B, perforated at b b, and preferably screwed upon the body A, or otherwise tightly fastened thereto. The opposite end is closed by the cap 0, screwed or otherwise fastened to the body A, and in this is formed the bearing 01 for the small crank-shaft D. To the inner end of the said crank shaft is secured the grindingdisk'E.

Fis the opposite grinding-disk held to move longitudinally in the body A and acted upon by the coiled spring G, which acts between the said grinding-disk and the cap B, and presses the teeth of the disk in contact with the nutmeg N, held between the two grindingdisks E and F.

The disk E is formed with radial rows of teeth 2 6' e The teeth a, ateach side of the center, are formed alike and have an inverted- V shape, their edges thus ranging transversely to the direction of the row .of teeth. The teeth e are beveled rearwardly from their front vertical end, presenting a cutting-edge at said front end. The teeth e are similar to the teeth e, but oppositely beveled. The teeth ecut grooves in the nutmeg and the teeth 6 e shave off the ridges thus formed. The teethfif', and f of the disk F, are like the teeth 6 e e of the disk E and need no further description.

The disk F is guided in its movement in the body A by the ribs g g, formed on the body A, and said disk is formed with grooved arms or extensions h h, which embrace the said ribs and prevent the said disk from turning out of place. Said diskis also formed with openings 2', through which the grated nutmeg may pass to the cap B through the openings 17 of which the fine nutmeg may be shaken as pepper is shaken from a common pepper-box.

n n represent stops on the ribs 9 to limit the inward movement of the grinding-disk F.

In use the cap B, spring G, and grindingdisk F are to be removed and a nutmeg or other substance to be ground placed in the body on the grinding-disk E. The said parts are then to be replaced. The spring G being of considerable tension will press the disk F forcibly against the nutmeg or other substance, which in turn will press the nutmeg or other substance against the grinding-plate E, so that when the latter is revolved the teeth of the grinding-plates will grind off the nutmeg, or grind or pulverize the substance acted upon by the disks. The nutmeg or other substance will be ground in quantities as used and shaken from the device as above stated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a grater, the combination,with a hollow body, of a removable perforated cap at oneend,a spring-supported grating-disk fitted within the body at said end and formed with openings or perforations, and a crank fitted in the opposite end and carrying a second grating-disk, the perforated disk and perforated end cap forming the exit for grated material, substantially as described.

2. The grinding-disk E, formed with radial rows of teeth e 6' 6 each tooth e being of inverted-V shape and ranging transversely to the direction of its row of teeth, and the teeth the opposite longitudinally-movable grinding-disk F, and the spring G, arranged to to press constantly upon the disk F, substantially as described.
