DAVID GAY AND JOHN lI. PURKISS, OF LONG BAR, CALIFORNIA.

IMPROVED QUARTZ-CRUSHER..

Specification forming part ofLetters Patent No. 43,304, dated June 28, 1864.

To all whom it may concern:

Be it known that we, DAVID GAY and JOHN H. PURKISS, of Long Bar, in the county of Yuba and State of California, have invented a new and usefulV Improvement in Hydraulic Quartz Crushers; and we do hereby declare that the following is a full, clear, and ex 1ct description of the same, reference being had to the accompanying drawings, making a part of this specilication, in whichv Figure l is a side elevation 5 Fig. 2, a plan.

This invention consists in the attachment of a waterwheel to the side of the ordinary crushing-wheel of a Chillian mill,7 so that the said water-wheel will travel around in the same path as the crushingwheel, and will furnish motive power for driving thc mill. Each crushing-wheel may, if desired, have two water-wheels attached to it, one upon each side of the crushingwheel, as indicated in red outline, Fig. 2.

Quartz-mills made according to our improvement may have one, two, or more crushingwheels and attached water-wheels, according to the supply of water or the requirements of the builder.

The foundation A, annular basin B, in which the crushing-wheels move, and the central pivot, G, around which the crushing-wheels D travel, are, together' with the wheels D, constructed in the ordinary manner, well understood by practical mill-wrights. Upon the inner side of each crushingwheel D we attach an overshot water-wheel, E, which is con structed according to any of the well-known methods. As shown in thedrawings, the buckets F are attached to an inner drum, G, the buckets and drum being arranged between two tlan ges, H H. A horizontal shaft, I,passes through the crushingwheels D, and also through the water-wheels E. This shaft has an eye or aperture at its center, where it receives the central pivot, C, as shown in Fig. 1. Each crushing-wheel and its attached waterwheel turns loose upon shaft I. Between the two water-wheels and rising from the shaft C are two standards, K K, upon the upper extremities of which is mounted a water-trough, L, which extends across over both waterwheels. There is an aperture, M M', at each end of this trough L, but on opposite sides. When a running stream or supply of water is allowed to flow into the trough L, the water issues through the apertures M M upon the buckets of the water-wheels, as shown by the arrows, and sets them in motion, thus causing the crushing-wheels also to move and travel around in the basin B and crush the quartz contained therein. Thus the crushingwheels, water-Wheels, and supply-trough, together with the horizontal shaft I, all move together. As the wheels revolve the Water brought down in the buckets is discharged upon the aprons N, one of which is placed in front and at the lower part of each Wheel E, the aprons N being supported by arms O O, which are saddled across the central shaft, I, in the manner shown in Fig. 1, a filling-block or bar, S, being placed between shaft I and the bars O, as shown in Fig. 1. The aprons N receive and conduct the waste water away from the wheels into the sewer pipes P, and

thus prevent it from flowing into the basin B.-

To assist in conducting the water toward the pipes P, the central part of the foundation Q is made concave, as shown. The outer edge of the basin B is provided with a perforated screen, R, to prevent the undue escape ofthe quartz. The mill is also to be furnished at other points with the channels, sluices, screens, and pockets necessary or convenient for such machines, to assist in saving or preventing the waste of the substance to be crushed.

This mill may be used for crushing all kinds of ores and other substances.

We do not confine ourselves to any particular details in the construction of our mills, be cause these may be varied according to the ordinary skill or desire of the mechanic or owner.

Having thus described our invention, what we cla-im as new, and desire to secure by Letters Patent, is

1. The attachment of the water-wheel to the side of the crushing-wheel, substantially in the manner herein shown and described, so that the water-wheel will drive and travel with the crushing-wheel, all as set forth.

2. The combination,` with the water-wheels, of the water-conducting aprons, substantially as herein shown and described.
