GRINDING-MILL. No.183,184. Patented 0ct.10, 1876.
UNITED STATES PATENT EEIGE.
BENJAMIN e. MARTIN, 0E NEW YORK, N. Y.
IMPROVEMENT IN GRlNDlNG-MILLS.
Specification forming part of Letters Patent No. 183,184, dated October 10, 1876; application filed September 2, 1876.
To all whom it may concern:
Be it known that I, BENJAMIN G. MARTIN, of the city, county, and State of New York, have invented a new and useful Improvement in Grinding-Mills, which improvement is fully setforth in the following specification, reference being had to the accompanying drawing, in which- Figure l represents a longitudinal vertical section of my improvement. Fig. 2 is a vertical cross-section thereof, taken in th'e plane a: w, Fig. 1.
Similar letters indicate corresponding parts.
My improvement is especially adapted to that class of mills in which the grinding parts consist of a metallic cone, revolving within a correspondingly-shaped shell or concave; and it consists in combining a crushing-cylinder, which is provided with one or more spiral blades on its outer surface, and a crushingshell with said grinding-cone and grindingshell, the whole being so arranged that when corn or other grain is fed to the crushingshell, and a revolving motion is imparted to the crushing-cylinder, the material is crushed by the action of the said cylinder and shell, while at the same time it is conveyed in a crushed state to the grinding-cone, and by this means the operation' of grinding the material is greatly facilitated. It consists, also, in forming a chamber'on the upper part ofthev crushing-shell to receive the material to be ground, and by which such material is fed uniformly to the shell, as hereinafter fully set forth.
In the drawing, the letter A designates the grinding-cone, and B is the grinding-shell or concave of my mill, which parts are made of the usual shape. O is the crushing-cylinder, on the outer surface of which are arranged a series of spiral blades, d. This cylinder C is mounted on a shaft, e, having its bearings at one end in the head of the crushing-shell, marked F, and at the other end in the end of the grinding-shell B; and to this shaft e is secured a winch, Gr, for giving motion thereto and to the crushing-cylinder. The inner surface of the crushing-shell F is roughened, as shown in Fig. 2, in any suitable way, and on the upper part of said shell is placed a hopper, H. Said shell F, moreover, is supported on standards I I. The grinding-cone A and crushing cylinder C are cast or otherwise formed in one piece, so that one forms a continuation of the other. The material to be ground is placed in the hopper H, and is thereby fed to the crushing-shell F, the crushingcylinder C being at the same time revolved, so that the material is caught or taken up between the spiral blades d of said cylinder, and is thereby carried forward to the grinding-cone A. As the material is carried forward by the spiral blades d, it is rubbed against the inner surface of the shell F, and by this means it becomes broken or crushed previous to being ground. The letter J designates a chamber formed on the upper part of the crushing-shell, F. This chamberJ is situated adjacent to the hopper H, and extends nearly the entire length of the shell F, so that the material placed iu the hopper H fills up the chamber, and is thereby fed uniformly to the crushing-shell.
What I claim as new, and desire to secure by Letters Patent, is-
l. The combination, With the crushing-cylinder C, provided with a grinding-cone at one end, and with spiral blades around the cylindrical portion, of the casing F, provided with a longitudinal feed-chamber, J, on top, and a concave grinding chamber at one end, substantially as herein set forth.
2. In combination with the crushing-cylinder C and casing F, the longitudinal semi-cylindrical feed-chamber J, with plain inner surface, located above the crushing-cylinder, substantially as herein set forth.
In testimonyr that I claim the foregoing I have hereunto set my hand and seal this 30th day of August, 1876.
