ALPHONSO L. ANDERSON WILLIAM T. ANDERSON, OF TOLLAND, CONN.
GRINDING-MILL.
SPECIFICATION forming part of Letters Patent No. 322,773, dated July 21, 1885.
Application filed January 11, 1885. (No modeh) To all whom it may concern.-
Be it known that we, ALPHoNso L. ANDER- soN and WILLIAM T. ANDERSON, both of Tolland, in the county of Tolland and State of Connecticut, have invented a new and Improved Grinding-Mill, of which the following is a full, clear, and exact description.
This invention relates to certain new and useful improvements in grinding-mills having two revolving stones.
The object of our invention is to provide for the separating of the stones should a hard substance pass between them.
The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a perspective View of our im proved grinding-mill. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a detail cross-sectional view of one side of the frame, showing the construction of the hinge of the swinging part.
The shaft or spindle A at one end is journaled in boxes on a frame, B, provided on the sides with trunnions or pivots O, which project from angle-pieces O on the frame 13 into boxes D on the top rails of a frame, E, between the sides of which the frameB is located and between which the frameB is adapted to swing. The other end of the shaft A is journaled in a journal-box, F, having a detachable top, F, and secured on a crossbar of the frame E.
On one end of the spindle A a belt-pulley, G, is rigidly mounted, and on the other end a sleeve, H, is held by a set-screw, H, the said sleeve being provided with a flange, H to which and part of the sleeve H one grindingstone, J, is secured. The other stone, K, facis closed, and a neck, N, is formed on the sleeve M, with which neck a hopper is connected. The sleeve L is adapted to revolve on the spindle, and carries a belt-pulley, O.
A conveyer-screw, P, is formed within the sleeves L and M on the spindle and extends from the neck N to the inner end of the sleeve L. A casing, R, surrounds the stones J K.
So far the mill described does not differ essentially from some that have been previously constructed, and we make no claim thereto, the novel. features in the present invention consistingin the spindle-adj usting mechanism, which will now be described.
S and S are screws for acting on the spindle and adjusting the stones. The right-hand screw, S, is passed through a nut, V, held to slide but not rotate in a frame, T, on a bracket, 25,- and between the said nut V and the end piece, w, of the bracket, through which the screw also passes, a series of rubber cushions, T, is placed, so that in case a hard substance is passed between the stones the stones can give sufficiently to let the hard substance pass, when the cushions T, being relieved from compression, force the stones back again.
The nut V is in the present instance made rectangular, and fits loosely within a squared opening in the frame T, so that the said nut may slide but not rotate in said frame. Of course any equivalent means of preventing the nut from turning, while allowing it longitudinal movement, may be usedsuch, for instance, as a tongue-and-groove connection. The lefthand screw, S, is passed through a spring-bar, S that has hooked ends 8 (see Fig. l) engaging the eyebolts s, projecting from, the end cross-bar of frame B. The bar S is strengthened at the point where the screw S passes through it by a sleeve, S. This screw S centers the left-hand end of the spindle, as shown in the drawings. The bar S also supports the weight of the spindle when the said spindle is in avertical position. The spring-bar S is also intended to press the spindle back firmly against the adjusting-screw S, so that in the frame, constructed to slide but not rotate therein, the screw S, passed through the apertured arm and through the nut, and the elastic washers on the screw between frame T and arm w, substantially as set forth.
2. The combination, with the frame, the spindle, and the stones, of the eyebolts 8, secured to the frame, the bar S having hooked ends engaging the said eyebolts, and the screw S, passed through the bar to center the spindle, substantially as set forth.
3, The combination, with the frame, the spindle A, and the stones, of the spring-bar S, the centering-screw S, the bracket t, hav-
