.CENTRIFUGAL: ORE-FILTER.

QPECIPICAI'ION forming part of Letters Patent No. 315,398, dated April .7, 1 885.

. Application filed November 6, 1884. (No model.) r

To aZZ whom it may concern:

Be it known that I, THOMAS T. 'EYRE, a citizen of Garlisle, Grant county, New Mexico,

haveinvented certain new and useful Improveto discharge the valuable properties and the refuse matter from different outlets; to which end my invention consists in the construction and combination of parts hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a central vertical section, part in elevation, of my centrifugal ore-filter; and Fig. 2 is a horizontal section at w as, Fig. l.

A represents an outer shell or kettle mounted on a fixed frame, 13, and provided with a cover, 0, which is removably fastened onto the kettle by screw-bolts D or otherwise.

E is a screw plug or cap closing tightly the hole at which the pulverized ore is admitted to the kettle.

F is a basket or screen made of perforated metal and mounted on the hollow vertical shaft G, to revolve therewith. The shaft is revolved by any usual means, such as the beveled gear-wheels J.

H represents a series of ribs on the inner face of the screen to stiffen it under the load which it has to carry. These ribs are curved and placed somewhat tangential to the central shaft or spiral, to assist the centrifugal action of the revolving screen to force the semi-fluid ore against the sides of the screen.

Irepresents aseries of bracing-arms secured at their inner ends to the shaft G, and at their bottoms to the screen F. Thesearms brace and stiffen the attachment of the screen to the shaft, and they are spirally curved, like the ribs H, to assist the centrifugal action.

The upper edge of the screen F is provided with an inward flange, K, to prevent the ore from slopping over.

or'less as it is lowered or raised by being The hollow shaft G is provided with ports .L, which serve as the exit of the refuse matter. M is a valve fitted to cover the ports L more screwed down or up through the screw-thread- Ois the hand-wheel of the valve, and P is a ing, thereby washing the refuse out through the ports.

Q, is a water'pipe pointing toward the ports L, and adapted to direct a stream of water butler pressure onto the refuse matter which gradually gathers over the ports in discharg- R is a pipe for the admission of steam when S is a pipe for the admission of gaseous fluids such as aqua ammonia, hyposulphite of soda and lime, &c.hot water or steam be;

ing used as a solvent to assist in disintegrating the ores and dissolving the metals. This pipe is closed at its end and perforated along its sides, and it is bent from a vertical position at a little distance from the side of the screen toward the center to lie across the direction of travel of the ore, that it may distribute the gas throughout the mass of ore.

'I is a water-pipe entering a distributer, U,

which is a passage on the outside of the kettle and connected with the interior thereof by a great many fine holes for the purpose of distributing the water from top to bottom of the kettle to wash the screen while discharging.

V is a similar water-pipe, and it maybe similarly connected with the kettle, or it may enter directly into the kettle, as shown,

W and Y are discharge-pipes, which may be connected with diflerent receptacles-the one to hold the richer and the other the poorer All the outlet and inlet pipes are provided too with stop-cocks by which they may be put in service or be stopped at pleasure.

The pipe W may be used to discharge the liquid rich in gold, silver, copper, 850., and the poorer liquids may be discharged by the pipe Y. Any number of these pipes may be used to separate the fluids as much as desired.

When the screen or basket is reversed, the ribs H and I help the discharge of mud or light refuse by drawing it centrally toward the discharge-ports L. The fine particles of metal mingled with the semifiuid mass are heavier than the sand or mud particles, and are therefore thrown out through the periphery of the basket by centrifugal force and run down in the kettle to the discharge-valves W and Y. That metal which is the heaviest sinks the lowest, and one of the said valves may be placed lower or nearer center than the other to select and discharge the heaviest ore. The outlets L are within the basket or screen F, and serve to discharge the mud or light refuse.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the kettle A and the screen F, vertically journaled therein, of the cover 0, secured thereon with screw or swing bolts, and the screw-plug E, fitted in the lid, as shown and described.

2. The combination, with the kettle A and screen F, vertically journaled therein, and the removable cover 0, of the pipe S, passing through the cover at some distance from the edge thereof, bent toward center, closed at the end, and perforated along its sides, as and for the purpose specified.

3. The combination, with the kettle A and the screen F, of the hollow vertical shaft G, supporting the screen, and the valve M, provided with a screw-shank and external handwheel, 0, and a check-nut, P, the hollow shaft being provided with ports L, substantially as shown and described.

4. The combination, with the kettle A, the

screen F, and its vertical shaft G, of the ribs H, extending from or near the top of the screen down its sides to near its center of revlution in a spiral direction, as shown and described.

5. The combination, with the kettle A, the screen F, and its vertical shaft G, of the arms I, secured at their inner ends to the said shaft, secured along their bottoms to the screen, and extending away from the shaft spirally, as and for the purpose specified.

6. The combination, with the kettle A and the screen F, vertically journaled therein, of the passage U, extending from near the top to near the bottom of the kettle and connected therewith throughout its height by perforations in the kettle, and the pipe T, connected with passage U, as shown and described, for the purpose specified.
