GRATER.

SPECIFICATION forming part of Letters Patent No. 673,895, dated May 14., 1901.

Serial No. 24,137. (No model.)

To all whont it may concern.-

Be it known that I, SOPHIE BLIoKMAN, a subject of the Czar of Russia, residing at New York city, borough of Manhattan, county and State of New York, have invented certain new and useful Improvementsin Graters, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a device for grating such materials as are generally used in the preparation of foods--for example, horse-radish, lemons, or vegetables of any kind.

The principal objects of the invention are to protect the hand of the user from coming in contact with the grating-surface, and, further, to provide a grater in which the grated particles are prevented from being scattered to any considerable extent, and in which the fumes or gases arising from the grated material are practically confined within the grater, so as not to be inhaled by the user.

To these ends my invention consists in the various novel and peculiar arrangements and combinations of the several parts of the device, all as hereinafter fully described, and then-pointed out in the claims.

I have illustrated a type of my invention in the accompanying drawings, wherein Figure 1 is a perspective view of my improved grater. Fig. 2 is a view of a section of the grater, the plane of which section extends vertically and centrally through the grater. Fig. 3 is a sectional view of the upper portion of the grater, together with the scraper. Fig. 4: is a horizontal sectional view of the grater, taken on a plane indicated by line 4 4., Fig. 2.

Referring to the drawings, in which like numbers of reference indicate like parts throughout, 2 is a grater, which in the present construction consists in a hollow truncated cone, which is formed with the usual gratingperforations 3, which do not extend to the upper and smaller end thereof, so that the cone at such end is provided with an imperforate portion a. The upper end of the conical grater is sealed by a cap 5, on which is preferably mounted a handle 6. Within the grater is arranged a scraper, consisting in a strip 7 of stiff resilient material, which is formed U-shaped, with the ends thereof flaring outwardly, so as to conform to the shape of the interior of the conical grater. This scraper is inserted within the grater, so that its two members lie flatly against the interior wall thereof, and the upper end thereof is secured rigidly to the handle 6, which is mounted so as to be rotatable. By turning the handle 6 the scraper is moved around the interior surface of the grater, so asto scrape from the interior of the grater any material which may lodge upon the interior wall thereof orin the grating-holes. The material thus dislodged from the scraper drops down within the grater, where it accumulates with the grated material which falls through the grating-holes during the the operation of grating. In this way the interior of the grater is very easily kept clean.

The conical grater is inclosed by a hood or shield 8, which is shaped like a truncated cone, and it is shorter than the grater, but is considerably larger in diameter than the grater in order to provide a space between the grating-surface and the interior of the shield. This shield is made of suitable imperforate material, and it is closed at its upper end by means of a collar 9, fixed upon the interior thereof, and an annular flange 10, which rests upon the solid portion a of the upper end of the grater, so as to provide a bearing at such point. The shield 8 is formed with an elongated opening 11, extending from near the bottom thereof upwardly to a point some distance below the collar 9, located upon the interior of the shield. The material to be grated is introduced through the opening 11 and is pressed by hand against the grating-surface, over which it is moved up and down in order to effect the grating. opening 11 is of such narrow width as to prevent the hand of the user from entering the same and coming in contact with the grating surface in the act of grating, and I thereby provide a safeguard against the hand of the user being lacerated by the grater. This shield or hood 8 serves as a means for inclosing the grating-surface, thereby preventing The the gases or fumes which arise from the grated material from being inhaled by the user. In grating some materials-such, for instance, as horse-radishthe fumes or gases coming from the grated material are so very strong and pungent as to render the act of grating a very disagreeable one. This drawback is overcome by my construction, as the gases or fumes are confined within the grater itself, which is closed at its upper end, and within the shield or hood, which is open only at the point where the material to be grated is introduced to the grater. Another important advantage of housing the grater is that the grated material is not exposed to the outer air, as in many cases, and accordingly it will not lose its strength so readily or become dissipated. Moreover, in my construction the grated material is not scattered about to any considerable extent, as it falls within the base-lines of the grater and the surrounding shield, wherein it is confined.

The grater and the shield are so construct ed that either one or the other may be rotated in order to present a new grating-surface in case the one in use becomes clogged with the grated material. I show the lower end of the conical grater as extending slightly below the lower end of the conical shield, so that when the device is stood in upright position for use the weight of the structure is thrown upon the grater, which is thus prevented from wabbling. The grater is thus also enabled to receive pressure from the hand of the user, which is placed upon the top of the device when it is being operated, and it is thereby held steady under the motion of grating. When the device is constructed so that it rests upon the lower end of the grater, as shown in Fig. 2, it is necessary to lift the device by the handle with one hand and holding the shield with the other to slightly turn the grater within the shield in order to present a new grating-surface. Of course a new grating-surface may be brought into play by turning the shield on the grater; but this would necessitate the user changing his position somewhat in order to reach the openingll in the hood.

It will be noted that the opening 11 in the side of the hood extends longitudinally of the same, so that in rubbing the substance to be grated over the grater the same is done by an up-and-down motion, while the upper end of the device is held by the other hand of the user. The long edges of the opening are rounded by turning in the edge of the material, as at 12, so that the substance in being grated has a smooth surface to be guided over, and these long edges of the opening acting thus as guides facilitate the operation of grating the material. It will be further noted that by virtue of having the device coneshaped and with considerable inclination to the walls thereof the device can be handled 'with less difficulty than if the grater and the hood were of a cylindrical shape, since the large base afforded by my improved form gives a greater stability to the device than it would otherwise have.

My improved grater may be made of any suitable materials which are used in such articles, and, if preferred, the shield may be made of glass or some kind of earthenware. The device may of course be used for grating any kind of substance, and as the grate and shield are loosely put together such parts may be readily separated in order to clean or repair the same. I wish to be understood as not limiting my invention to the precise construction herein shown, as various modifications may be made in the different parts thereof without, however, departing from the spirit of the invention.

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