CHARLES C. LANE, OF SAN DIEGO, CALIFORNIA, ASSIGNOR TO HUGHES & 00., OF SAME PLACE.

RQLLER QUARTZ-MILL.

EPECIPICATION forming part of Letters Patent No. 456,623, dated July 28, 1891.

Application filed June 4, 1890. Serial No. 354,231. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES 0. LANE, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented an Improvement in Roller Quartz-Mills, of which the following is a specification.

My invention consists in a new and improved roller quartz-mill for crushing and .pulverizing ores, which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 isa side View of my new and improved roller quartz-mill. Fig. 2 is a top plan view of the mill. Fig. is a central vertical sectional view of the same 5 and Fig. 4 is a transverse sectional view, on an enlarged scale, of the circular trough and the ore-guards.

The same letters of reference indicate cor responding parts in all the figures.

Referring to the several parts by letter, A indicates the platform of the mill, upon which is constructed a tank or receptacle B, which is loaded with rocks, water, or any othersuit able weight. To the platform-timbers A are secured the pairs of hangers C C, in which are mounted the axles D of the roller-crushers E. The inner hanger G has a universal or pivot joint G which allows the axles to play sutliciently as the wheels travel around in the circular trough, the openings in the outer hangers C being suflicientl y large to permit of this slight movement. On the outer ends of the radial axles D are secured the wheels or roller crushers E, the hubs of which extend into the outer bearing-box, as shown. These rollers travel in a circular trough F, which is U-shaped in cross-section and which is supported upon bottom timbers I, which in turn rest upon the foundation-timbers J. In the bottom of the U-shaped trough are fitted the removable shoes K of harder metal,which may beremoved when worn and replaced by new ones.

Around the circumference or outer edge of the circular platform A is secured the endless circle or series of cogs or teeth L, with which a cog-wheel M on the upper end of a vertical shaft N meshes. On the lower end of this shaft is a bevel-pinion O, meshing with a similar pinion P on the drive-shaft Q, which may be driven by any suitable power.

I do not confine myself to placing the circle of cogs around the edge of the platform, as here shown, as lD may be placed beneath the platform, near the edge thereof, with the same results.

Upon the center of the middle timber I is bolted a fulcrum-block R, having a vertical socket or bore R, in which fits the lower end of a pivot S, which is bolted at its upper end to the center of the platform. The lower end of this pivot S does not reach down to the bottom of the hole B, so that while it serves as a pivotal guide for the revolving platform, holding it always on the same center, all the weight of the loaded platform is thrown as it is revolved upon the crushing-rollers E. This is the object of the weight placed upon the loaded platform-to give great power to the crushing-rollers.

The upper edges of the U-shaped trough F are formed with the annular grooves F in which [it the lower edges of the ore-guards T T, which keep the ore in 'place while it is being crushed in the trough Fand which can be removed when not required.

The mill is provided with an inclined outlet or chute \V, upon which maybe placed suitably-constructed plates for catching or retaining the gold or silver.

From the foregoing description, taken in connection with the accom iianying drawings, itwill be seen that my roller quartz-mill is simple, inexpensive, and durable in its construction and exceedingly powerful and effective in its operation. The immense weight of the great load of rocks in the receptacle on the revolving platform gives very great crushing-power to the wheels, the entire weight of this load being thrown directly on the crushing-wheels E by my peculiar construction.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the circular trough, the loaded platform having the outer hangers 0, formed each with a bore of greater diameter than the revolving axle which passes running in the circular trough, the fulcrum; block R, formed with the vertical bore, and the guidepivot S, secured centrally to the loaded platform and projecting into the vertical bore R, but terminating above the bottom of the same, substantially as set forth.

In Witness whereof I have hereunto set my hand and seal.

CHARLES C. LANE.
