ORE CONCENTRATOR.

APPLICATION FILED APR.26.1907.

WITNESSES A TTORNEYS UNITED STATES PATENT BAY HALLIE MANLEY, OF SAN FRANCISCO, CALIFORNIA.

onn-concnn'rna'ron.

To all whom it may concern:

Be it known that I, RAY HALLIE MANLEY, a citizen of the United States, and a resident of San Francisco, in the county of San Fran- E cisco and State of California, have invented a I i signed for se fragmentary section new and Improved Ore-Concentrator, of which the following is a full, clear, and exact description.

This invention has reference to an imroved ore concentrator, more es ecially dearating and saving ne or flour gold from t e tailings, which it does both thoroughly and rapidly when the material is either in the wet or dry state.

The invention broad y stated, comprises a revoluble and vibratory bowl in which the tailings containing gold or other metal. is placed. As the tailings are lighter than the gold, they are worked to the surface by the vibratory motion and thence carried over the top edge of centrifugal force develo ed.

, Reference is to be ha to the accompanying drawings forming apart of this speclfication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central, vertical section through the preferred form of my improved ore separator; Fig. 2 is a fragmentary v ew of the vibrating mechanism, and Fig. 3 1s a through the bowl, on an enlarged scale, illustrating the manner in which the particles of metal collect behind the ribs thereof. I

More specifically stated, the invention com rises suitable supporting standards 1, 1 whic are connected together at their upper ends and provide bearings for a cross-shaft 2 intermediate their height, said shaft carrying between the standards a centrally-arranged cam 3 and at one side thereof a bevel gear 4. A pulle 5 is fixed to the shaft 2 at the outside oft e standards, by which the shaft may be driven from a suitable source of power.

Journaled in the connecting portion of the standards 1 is a vertical shaft 6, having a head 7 at its lower end normally pressed to the periphery of the cam 3 by a spring 8, surrounding said shaft and interposed between the head and a small bevel gear 9. The gear 9 is in mesh with the ear 4, and is slidably splined on the vertica shaft 6 by a pin or screw 10, rojecting into a slot 11 cut in the shaft for t is purpose. The u per end of the shaft 6 above the standar s 1 is screw- Specification of Letters Patent. Application filed April 26, 1907. Serial No. 370,440.

ranged radia ly of the bowl under the action of the Patented March 3, 1908;

threaded for receiving nuts 12 and 13, preferably having extended opposed faces tween which a bowl 14 is clamped. This 'bowl receives the crushed ore or other material containing the particles of gold or other metal, and is constructed on its inner face with a series of concentric ribs 15 dpreferably V-sha ed in cross section an arthe bowl, the bowl being fed with the crushed ore ,at its center in the space inclosed by the inner rib, as through a hopper 16.

Surrounding the upper edge of the bowl 1 1:, into which the latter discharges when in op eration, is a doubled apron 17, which droops about the bowl and has an inclined bottom discharging through a suitable orifice 18 arranged at one side of the machine. This apron is preferably supported from the standards 1 by brace-bars 19 located at suitable points.

In; the operation of the machine, the crushed ore or other powdered material containing particles of gold or other metal, is fed, a small quantity at a time, to the center of the bowl through the hopper 16, the ma terial being either in the wet or dry state. If in the wet state, the interior of the bowl is amalgamated. As the bowl is rapidly revolvedunder the action of the driving mechanism, it is also vibrated by the bumping action given to the shaft 6 by the cam 3, this o crating to work the lighter material to t e top.. As this material comes to the surface it is, under the influence of the centrifugal force develo ed by the revolution of the bowl, successive y worked over the ribs 15 and discharged into the doubled apron, where it asses through the orifice 18. The gold or ot er metal will lodge behind the ribs as the tailings float over, as illustrated in Fig. 3. The machine is found in actual practice to erform the separating operation thoroug y and rapidly, in fact more so than the ordinary plates or tables.

It is apparent that various changes in the construction from that described may he resorted to, without departing from the nature of my invention, as set forth in the claims annexed. 1

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. An ore separator, comprising standards connected together at thelr upper ends, a cross-shaft journaled in the standards, having a cam and a bevel wheel fixed thereto, a

vertical shaft journaled in the connectingortion of said standards, having a head, a bevel wheel in engagement with the firstnamed wheel, slidably splined to the vertical shaft, a spring interposed between the lastnamed wheel and the head of the shaft, normally forcing said head in contact with said cam, a bowl fixed t0 the upper end of said shaft, and an a ron surrounding the upper edge of said bow and fixed to said standards.

2. An ore concentrator, comprising a vertical shaft carrying a bowl, a cross shaft having a cam on which the lower end of the vertical shaft bears, a bevel splinedto the vertical shaft near its lower end, a bevel gear fixed to said cross shaft in mesh with' the first-named bevel ear, and a spring interposed between the st-named bevel shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
