GRATER.

EiPIlCIFICATION forming part of Letters Patent No. 378,127, dated February 21, 1888.

Application filed October 16, 183d Serial No. 216,441. (.Model.)

To all whom it may concern:

Be it known that I, EDWIN Biinrztnv, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certai 11 new and useful Improvements in Graters; and I do doclare the following to be a full, clear, and exact description of the invention,sueh 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, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to graters; and the improvement consists in the novel features more fully hereinafter set forth and claimed, and shown in the annexed drawings,in which- Figure l is a side view of the device, parts being broken away. Fig. 2 is a side view of a cutting-cylinder of ordinary construction adapted to tit in the case and interchangeable with the grating-cylinders. 3 andlare side views of the interchangeable grating-cylinders. Fig. 5 is a detail perspective view of one of the rings composing the cylinder shown in Fig. 4; and Fig. 6 is a section on the line X X of Fig. 1, showing the lower portion of the standard broken away.

The object of the improvement is to obviate some of the objections pertaining to like devices commonly in use, and to devise a construction which will be simple and compact in arrangement, economical in cost, easy to manage, readily cleaned, quick in operation, e'lhcient in use, and not liable to get out of repair.

The gist of the invention is the grating-surface, which is so constructed that it presents a practically smooth surface, which is unlike those commonly in use, as it has no projecting points or ragged edges to catch into and injure the hand.

Graters commonly in use are made of punched metal, usually tin,the punching of the holes causing a raised ragged edge to surround the holes on that side of the tin opposite from which the punching is done. "hese raised ragged edges are the cutting-edges, and have depressions between them which quickly fill or clog up, retarding the progress of grating and storing much of the substance in the spaces intervening between the holes, instead of delivering it free for use.

My improvement is the construction of agrating-surface which has perforations formed therein by removing a portion of the substance from the body.

The body of the grater may be molded or cast with the perforations formed therein, or said perforations can be formed by punching or drilling. While my improved grating-surface can be and is intended to be adapted for use as ordinary grating-surfaces,itis especially designed to be made into cylindrical form and snugly fitted into a casing provided with a hopper.

The casing A is of peculiar construct-ion, being cylindrical in form, open at both ends, and having a portion removed from its side, which is surrounded by walls forming a hopper, B. The standard 0, extending from the casing, has arms I) b branching laterally from its lower end. A set-screw, D, passed through the arm I), is adapted to hold the device in place upon any suitable support by the clamping of the same between the end of the screw and the arm 1/. The standard is preferably an integral part of the case, and the latter is disposed relative thereto in such manner that it occupies an inclined position, which adapts the cutting-cylinder to relieve itself of the grated substance. In practice the case is adapted to receiveany kind of cylinder, either for slicing or grating purposes.

Figs. 1 and 2show the cylinder E provided with a knife, Z, and is intended to be used for slicing only.

Fig. 3 shows a cylinder, F, for grating, in which the holes f are formed therethrough by cutting or stampin The cylinder may be formed first and the holes subsequently made, or the holes can be made in a sheet which is afterward bent into cylindrical forms.

Fig. i shows a cylinder, G, forgrating, composed of a series of rings, 9, having teeth or blades 9 projecting laterally therefrom. A. number of these rings are secured in any approved nianner, forming a gratingcylinder filled with perforations surrounded with partitioned walls having knife-edges. The rings are beveled to a knife-edge, and the blades are correspondingly beveled from front to rear, forming knife-edges. They are secured together, preferably, by bolts H, which are passed through perforated lugs ii, extending "inward from the inner side of each, as more clearly shown in Fig. 5.

It will be observed that the several cylinders are of the same diameter, so that they can be used interchangeably, according to the work desired to be performed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A grater composed ofa bodyxhavingportions removed therefrom at intervals, forming thereof or be removed therefrom at pleasure, and a stop or collar arranged to limit the downward movement of the grating-cylinder, substantially as set forth.

3. The grating-cylinder composed of a series of rings having blades projecting laterally therefrom.

4. The grating-cylinder composed of a series of rings sharpened to a knife-edge, and having blades projecting laterally therefrom which are beveled from their front edge.

5. The grating-cylinder composed of a series of rings sharpened to aknife-edge having blades projecting laterally therefrom, and provided with inwardly-projecting perforated lugs, and bolts passed through the lugs and binding the rings together, subsfantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
