Jv. MATZNER. l GRINDING MILL.
Untere rares Parar* 'tentent GRINDING-MILL.
SPECIFICATION forming part of Letters Patent No. 255,303, dated March 21, 1882.
Application lcd December 22, 1881.
wheat, but adapted to be used for reducingto a pulverized form many other substances; and
it consists principally in the peculiar` construction of the grinding-cone and shell for a more complete pulverization of the grain than heretofore, as fully hereinafter described.
In the drawings, Figure lis a side elevation ofthe entire device, Fig. 2 is a separate view of the revolving grinding-cone, and Fig. 3 a view of the stationary shell.
A represents a standard or frame, mounted on any-desired number of legs, B, of which three are here shown. Thisstandard forms a bearing for a vertical shaft, C, and also for a counter-shaft, D, passing transversely, and having at one end a crown-wheel, E, which engages with a bevel-gear wheel, F, on the vertical shaft C, and gives such shaft a continuous rotation.
Keyed on the shaft O is a crown-wheel, G,
which gea-rs with a pinion on a' shaft, 2, running in bearings 3 4 in arms 5 6 of the main frame. The shaft 2 has mounted upon its outerend a iiy-Wheel, 7, which regulates and steadies the motion. The arm 5 forms a supporting-guide, on which slides one end of a shaking screen, H, the other end of which is pivoted to a support, 8. A spring, 9, connects the screen to the arm 5.
' On the vertical shaft C are arranged teeth 10, which, as the shaft' revolves, strike against a pin, 1l, on the screen, and impel the screen in one direction, the spring immediately returning it. A constant reciprocating or shaking movement is thus given the screen by the rotation of the shaft.
The cone and shell 1 and K are shown separately in Figs. 2 and 3. The cone l is mounted on the shaft C, so as to turn with it. It is provided with circumferential spiral grooves of peculiar construction. Each of these grooves (No model.)
runs completely around thc circumference of the cone. Both the size and pitch ofthe spiral vary, the grooves becoming finer as they ap proach the bottom or base of the cone. Around The rotating cone [.runs in connection with a stationary shell,K. (Illustrated separatelyin Fig. 3.) It is internally a little greater in diameter than the cone I, and is held stationary by being bolted to the arms 5 5. 1t is, however, adjustable vertically in slots 16 in such arms, and may be held at any point inthe slot by a jam-nut.
The inside ofthe shell K is formed into grinding and cutting ribs 17, of slightly spiral pitch, as shown. In each of thesel ribs are formed notches, the notches of any two following ribs being placed alternately, as shown. The ribs between the notches are formed into sharp cutting-edges, so that the particles, after being caught and held by one of the notches, are torn by the opposite cutting-edge on the next rib, at the same time being carried down toward the discharge-opening. This combined cutting, grinding, and tearing motion is very effective, and the peculiar arrangement, construction, and relativefaction of the grooves and ribs of my movable and stationary grinding-surfaces are the main features of my invention. The construction of the grooves in the cone, whereby such grooves are carried completely around the circumference of the cone at avaryingpitch, accomplishes the grinding of the grain throughout the entire revolution of the cone, each particle being carried completely around the cone and down at a decreasing rate of speed as it grows finer until discharged.
P is a hopper, of common or ordinary construction, supported by the arms 5 5, or in any other suitable manner.
The pulverized material, leaving the grindin g-surfaces, falls upon the shaking screen, the ground material passing through into any Asuitable receptacle, the refuse and worthless ICO matter being carried over the end of the screen and discharged.
Power may be applied to the counter-shaft D in any suitable manner; but I prefer to connect ny belt to a horsepower, though when other power is accessible it could be used.
It will be understood that the vertical adjustment of the stationary shell in the arms is necessary in grinding material of ditferent grades of coarseness.
Having thus described my invention, what I claim is- 1. The shell K, having the spiral ribs, each rib being provided with a series ot' notches, the notches in any two adjacent ribs being arranged alternately.
