Application filed April 20, 1908.

ol Minneapolis, liennepin county, .3. unesota, have lllYiIrtf-d certain. new and uselul Improvements in Ore-Soparatin -ulachines, oi" which the following is a speeincation.

My invention relates to machiner r' designed to street a separation oi iron and other metals capable of magnetic influence from a body of other material, and the ohject oi the invention is to provide an apparatus of hu capacity and one in which the sopa ition of ore can thoroughly and rapidly performed.

The invention consists generally in various constructions an d combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a tical sectional view of an ore separating machine embodying my invention. Fig. 2 is a detail sectional view of the same. Fig. 3 is a detail view illustrating the construction of one of the circuit closing rings.

In the drawing, 2 represents a tank adapted to contain the material to treated, a su'ilicient amount of water being i tror'luced into the tank to render the material of proper consistency for separation.

is a valve controlling the water suppl O and i is an upright hollow shalt supported on a step 5 within the tank and carrying an agitating device consisting of a series or radial tubes 6 having perforations 7 through which air under pressure is delivered to tho tank from a pipe 8 connected with said hollow shaft. The air entering the mixture through the. revolving arms of the agitating device has the ellcct of stirring it up and preventing the ore from settling to the bottom of the tank. The shaft 4} driven through a gear 9 thereon meshing with a pinion 10 on a shaft 11 having a driving pulley l2.

A wheel 13 is mounted on a shaft i l and supported in a vertical plane with a portion depending within the solution in the tank. This wheel is arranged to revolve slowly and is divided into a series of sections 15. l have shown 8 of these sections laut a greater or less number may be employed, it preferred. in each section I arrange a series oi electro-magnets 1.6 having their polo pieces projecting beyond the periphery oi the wheel, as indicated in Fig. 1.

Upon the shaft 14 I arrange a series o'l rings 17 insulated from one another and from Specification of Letters Patent.

Serial No. l28,01.

said shal't, tho number ot rings corresponding to the number of sections in the wheel and each ring hoing in circuit vii h one side of thc oloctro-maguots oi one ol the sections, and all ol tho rings being in circuit with. a. dynamo (not shown), through hrushes l8 and a conductor it). A rirg '20 is provided having a brush 31 in circuit with the dynamo through a conductor 22, and the said ring 20 is in circuit with the other side of the electromagncts ol all of tho sections. The rings 17 are provided with contacting surl'aees 2S and insulating or non-conducting surfaces 24, tho brushes 18 sliding over said surfaces as the rings rcvo vo with tho shalt i l. Vith this arrangement it is evident that during a predetermined period in the revolution of the wheel 13 the circuit will he closed through the clectro-nragnets of each section and their pole pieces energized, and during another period in the revolution oi the wheel the circuit will be broken through the electromagnots and their polo pieces dcncrgizod. The rings 17 are so arranged that tho magnets will he energized when they are passing through the solution in the tank and will he denergivzed when they roach a point where the material collected on the pole pieces through magnetic attraction will, when ro lievcd, l all upon the inclined plate 25 and he conducted to a suitable receptacle. A brush '26 is arranged abov said plate and adapted to contact with tho pole pieces and sweep oll any particles of iron or other metal adhoriir' thereto. The groups ol' magnets are arranged in water-tight compartments in the sections 15 of the ring, their polo pieces only being exposed to attract the ore and separate it .trom the solution in the tank.

In the operation of tho machine tho tank is filled withwater to a point near the top and a quantity oi iinely ground ore introduced. The agitator is set in motion and air under pressure being discharged through the holes 7 will cause a violent agitation of the water and the pa 'ticles of ore to he held in suspension. The wheel 15 is now set in motion and an electric current turned on. As each group of clcctro-magnets passes through the solution a quantity of iron will adhere to the magnets and he carried out of the tank. Upon reaching a predc' ermiuod point the circuit will be broken through the magnets, their pole pieces demagnctized and the greater portion of the iron will fall upon the inclined plate L5. The revolving brush keeps the pole pieces clean, and upon reaching a point Where the magnets can enter the solution the circuit will be closed therethrough, the ore will collect on the pole pieces and the process n'niy be repeatefl as long 1as any iron remains in the solution.

I 0 mini as inv invention:

1. The combination, with a tank sclspterl to contain a liquid solution and a quantity of finely grounrl ore, magnetic separating element ino unted on said tank, a hollow she-l t depending witl'iin said. tank, a of tubes rs-distin roin said s" it near the not i l a torn of tank, neing an unobtubes and said i inont, said tubes 11 ving perforation i Walls, anal a pipe arranged to introduce air under pressure into said shaft.

2. T le combination, with a tank adapted to contain a liquid solution and a quantity of finely grouno ore, of it magnetic seperating element mounted on said tank, on agitatn'ingnetic s ing (lo *ioe provideil Within said tanl-t and comprising a hollow shaft, a series oi tubes radiating therefrom and having geril orations in their walls and means for supplying 2L fluid pressure to snicl shaft and tubes.

3. The combination, with {L tank, adapted to contain a liquid solution ind a quantity of finely ground ore, of magnetic separating element, there being unobstructed space beneath said separating element Within said tank, and an agitating device consisting of a hollow shaft and arms rzuiliating therefrom provided near the bottom of said tank anti errngeil to revolve therein, said agitating (lei ,e having means for (lelive ing a fluid. pressure into the lower portion of said tank, for the purpose syecilierl.

'itness whereof, 11love hereunto set my hand this 15th (lay of April, 1908.
