NITED STATES PATENT OFFICE,
IMPROVEMENT IN QUARTZ-MILLS.
Specification forming part of Letters Patent No. 56,793, dated July 31, 1866.
To all whom it may concern:
Be it known that I, HENRY PEARCE, of the city and county of San Francisco, and State of California, have invented a new and useful Machine for Crushing and Pulverizing Quartz- Rock, Stone, and any description of Ores; and I dohereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a section; Fig. 2, an elevation, and Fig. 3 a plan or top view.
To enable others skilled in the art to make and use my invention, I will proceed to describe the construction and operation of my machine.
I construct a cast-iron shell, A, of suitable size and strength, shaped conically, resting on and bolted to four or more pillars, B B. This shell, which may be made of common gray iron, is provided with a lining of hard white iron, C C, which admits of being replaced \vhen worn, and may either be made in one solid piece or in sections, accordingly as the size of the machine may renderitconvenient.
I also construct a pestle, D, of cast-iron, cast on the stem or shaft E,which is made of wroughtiron. This pestle D, which is also provided with an outer casing, HH, of hard white iron, rests on a stout cross'tree, F, which is suspended from the shell-bolts P P.
()n the upper portion of the shell A a hub, I, is cast, in which is fitted a bushing, G. This bushing, through which the stem or shaft E passes, is bored out eccentrically with its outer circumference, and which, when revolving, communicates a rolling motion to the pestle D.
To allow for the free play of the shaft E, the bushing G is fitted with a curved wedge, L, as shown in Fig. l, which easily accommodates itself to the motion of the shaft. Upon the upper portion of this bushing G the pulley fly-wheel K is keyed which gives motion to the machine.
The shell A has four (more or less) apertures, as shown at MM, surrounded by a hopper, T, by which the machine is fed.
By unscrewing or screwing up the bolts P P the cross-tree F may be raised or lowered,
by which means the machine may be set so as to crush finer or coarser, as desired.
The machine, as shown in the annexed drawings, is arranged to crush the ore in a dry state; but should it be desired to crush the ore wet the rim or flange R upon the pestlecasing H should then be made concave and the rim or flange S upon the lining C correspondingly convex, this to prevent a too rapid flowing off of the pulp. Again, when it is desired to use the machine simply as a breaker to break the ore into small pieces, and not to pulverize it, the casing H may be replaced by one having no rim or flange R, which would then permit the rock to free itself of the machine before being pulverized.
It may here be observed that my machine may be so arranged as to make the outer shell, A, partake of the revolving and rolling motion and the pestle D and shaft E remain stationary by bolting or otherwise fastening down the said pestle and freeing the outer shell, A- an arrangement which would accomplish the same result.
The operation of my machine is as follows: Motion is given to the pulley-wheel K, which, revolving the bushing G, communicates a rolling motion to the pestle I), and causes it to alternately close upon and recede from the sides of the outer cone or shell, C C, by which action any substance which may intervene is immediately crushed, and passing downward to the lower part of the machine, where the space gradually lessens, is crushed finer, and passes out when the machine is used as a breaker, but dropping between the flanges R and S when the machine is used as a pulverizer also, is then ground to any degree of fineness, and finally passes out of the machine' at O. i
What I claim as my invention, and desire to secure by Letters Patent, is
The construction of a conically shaped crushing-mill with an eccentric motion, as herein described, for the purposes and in themanner substantially as set forth.
HENRY PEARCE.
