To all whom it may 0011mm:

Be it known that l, Mosns DANKBERG, a citizen of the United States. residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Masticating-lilachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to a masticating machine which is adapted to mash or beat material so that it becomes a pulp, being particularly adapted for the mashing of potatoes and similar vegetables whereby the operation is quickly done and large quantities can be mashed in a short space of time, the machine being adapted for use in restaurants and similar situations.

The invention is further designed to provide a machine of this type which is smooth running and which provided with a particular lul'iricating installation which insures the lubrication of the main driving parts, but prevents any of the lubricant passing ito the casing itself so that none of the material being masticated will come in contact with any of the lubricant.

The invention is further designed to provide a machine which is easily cleaned, the masticating parts attached to the main shaft being easily removable and all of the parts being without minute crevices or small projections so that when the machine is taken apart each of the individual portions can be cleaned thoroughly and quickly.

The invention is illustrated in the accompanying drawing, in which- Figure l is a vertical section of the machine with the masticating portion in elevation, and Fig. 2 is a section on line 2, 2, in Fig. 1.

The device consists of a casing which is made in the form of a cylinder and is preferably cast in one piece and integral with the supports or legs 11 and the hopper 12, the hopper providing means for feeding material to the machine, the inlet formed by the hopper being located at one end of the machine and preferably at the top thereof.

On one end the casing is formed into a bearing 13 in which is rotatably arranged the operating shaft 1% which can be rotated by any driving means, but I prefer to employ the hand-wheel 15 having the handle 16 thereon. The inner face of the bearing 13 is provided with a circular recess 17 into which is adapted to be rotatably fitted the head 18 of the operating shaft 14;. These parts are permanently installed in the machine. The head 18 is provided with a recess 19, this recess being adapted to receive a projection 20 on the end of the main shaft 21. The projection 20 and the recess 19 are so formed that they co-act so that they rotate in unison, this being preferably brought about by making both the recess and the head rectangular in shape, the preferred form being square. The inner face 22 of the end of the casing, exclusive of the recess 17, is made flat and receives the disk 23 which is attached to the main shaft 21, the disk 23 rotating against the face 22 for purposes to be hereinafter described.

The bearing 13 is provided with an oil cup or any other suitable source of lubrication supply 24 which feeds oil into the oil passage 25 so as to lubricate the operating shaft 14 and its bearings the passage 25 ter minating in the lubricating channel 26 which has an outlet 27 passing into the oil pipe 28 so that lubricating material in excess of that required will pass down through the pipe 28. The lubricating material will pass around the head 18 in a sufficient quantity to lubricate it slightly and prevent its working hard, but any further spread of the lubricant is prevented by the fitting of the disk 28 against the face 22 so that the lubricant is insured in its confinement to the bearing 13 and does not pass within the cylinder 10 to come in contact with the material being mashed or masticated.

At the end of the casing opposite the bearing is an outlet plate 29. The casing is provided with lugs 30 in which is adapted to swing an eye 31 of a bolt 32, each bolt being screw-threaded and being provided with a nut 38 so that when the bolt 32 is swung between the lugs 34, which are arranged in pairs on each side of the outlet plate 29, the nut 33 can be screwed up on the bolt 32 against the lugs 34, as shown in Fig. l, and the outlet plate is locked in position. On its inner face the outlet plate
