MAGNETIC ORE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 607,984, dated July 26, 1898.

Application filed January 7 1898. Serial No. 665,976. (No model.)

To all whom it may concern:

Be it known that I, GERALD JAMES OREAN, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Magnetic Ore-Separators; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention has for its object to provide means to more effectively separate the magnetic from the non-magnetic particles of'magnetic ores when in granular form.

The invention may be said, briefly, to consist of aseries of stationary magnets arranged in the form of a downwardly-extending are having its upper end located adjacent to the outlet of a hopper, a non-magnetic carrier adapted to travel in close proximity to the face of said series of magnets and from said hopper to a receptacle located beneath the last magnet of the series, and a blower adapted to force a current of air downwardly through the space between the carrier and the outlet of the hopper, and therefore through the ore particles as they pass from the latter to the former.

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part of this specification, wherein like symbols indicate the same parts, and in which- Figure 1 is a longitudinal vertical section of a magnetic ore-separator constructed according to my invention and with the supporting-frame partly broken away; Fig. 2, a plan View thereof.

The frame 5 may be of any approved design and constructed of any preferred material. A shaft 6 is mounted transversely of this frame and has loosely hung therefrom, as at 7, a frame consisting, preferably, of a right-angled portion 8, supporting at its ends a series of preferably permanent magnets 9, arranged in the form of an arc and connected together preferably by mounting them in a wooden section 9, having its ends rigidly secured to the ends of said frame-piece 8, the ends or poles of said magnets projecting through said wooden section and having the faces of their ends flush with the outer surface thereof, while this magnet-carryin g frame is maintained in the position shown in Fig. 1

by means of a counterpoise 10. A hopper 11 series of magnets and with its inside face in close proximity to the poles of said magnets.

A blower operated from any available source is located, preferably, as at 14 and has its discharge-pipe 15 connected to a length ofpipe 16, slotted, as at 17, and extending above and parallel to the outlet-opening of the hopper and having its end closed and adapted to direct a current of air downwardly through the magnetic and non-magnetic particles as they leave the hopper.

In the operation'of my separator the particles of ore, magnetic and non-magnetic, running from the hopper, which has been presumably filled, will be precipitated against the cylinder, where the magnetic particles will be held by the attractive force of the magnets, thus, owing to the weight of said magnetic particles, causing the cylinder to rotate and carry said particles to the receptacle 19 at the lower end of the series of magnets, where they will drop from the cylinder, while the non-magnetic particles will drop directly into a receptacle 20, arranged below the outlet-opening of the hopper, the current of air from the blower meanwhile cleansing the particles as they leave the hopper of dust, chips, and other light non-magnetic particles.

What I claim is as follows:

1. A magnetic ore-separator comprising a series of stationary magnets arranged in the form of an arc; a hopper located adjacent to said magnets; a rotatable carrier adapted to travel across the surface of and in close proximity to said magnets and intermediate of same and said hopper, and said carrier be ing adapted to receive movement from the ore particles running from said hopper and adhering to said carrrier. l i 2. A magnetic ore-separator comprising a series of stationary magnets arranged'in the form of an are; a hopper located adjacent to said magnet; a rotatable carrier adapted to receive movement from the ore particles running from said hopper and to travel across the surface of and in close proximity to said magnets and intermediate of same and said hopper; and a blower adapted to direct a current of air between said hopper and carrier,

for the purpose set forth.

3. A magnetic ore-separator comprising a series of stationary magnets arranged in the form of anarc; a hopper located adjacent to said magnets; a rotatable carrier adapted to travel across the surface of and in close proximity to said magnets and intermediate of same and said hopper, said carrier being adapted to receive movement from the ore particles running from said hopper and adhering to said carrier; and a blower adapted to direct a current of air between said hopper. and carrier, for the purpose set forth.

4. A magnetic ore-separator comprising a frame; a shaft mounted in said frame; a series of magnets arranged in the form of an arc; means forsuspending said magnets from said shaft; a counterpoise mounted at one end of said series of magnets; a carrier consisting of a non-magnetic cylinder mounted upon said shaft and adapted to receive movement from the ore particles running from said hopper and travel around and in close proximity to said series of magnets; and means for feeding the magnetic ore in granular form to said carrier, for the purpose set forth.

5. A magnetic ore-separator comprising a frame; a shaft mounted in said frame; a series of magnets arranged in the form of an 35 arc; means for suspending said m'agnetsfrom said shaft; a counterpoise mounted at one end of said series of magnets; a carrier consisting of a non-m agnetic cylinder mounted upon said shaft and adapted to receive movement from the ore particles running from said hopper and to travel around and in close proximity to said series of magnets; means for feeding the magnetic ore in granular form to said carrier; and a blower adapted to direct a current of air through said ore while being fed to the carrier, for the purpose set forth.

6. A magnetic ore-separator comprising a frame, 5; a shaft, 6; a series of permanent magnets 9; right-angled frame 8; counterpoise 10; cylinder 12 adapted to receive movement from the ore particles running from said hopper; roller-bearings 13; hopperll; blower 14; discharge-pipe 16; and receptacles 19 and 20; all arranged substantially as described and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

GERALD JAMES OREAN.
