JAMESMASON MOOLAVE, FRANK HARRY KIRBY, AND ERNEST ROBERT OUMBE, OF DENVER, COLORADO.
ORE-SE'PARATOR.
SPECIFICATION forming part of Letters Patent No. 697,351, dated April 8, 1902.
Application filed May 10, 1901.
To all whom it may concern:
Be it known that we, JAMES MASON-MO- OLAVE, FRANK HARRY KIRBY, and ERNEST ROBERT GUMBE, citizens of the United States, and residents of Denver, in the county of Arapahoe and State of Colorado, haveinvented a new and Improved Ore-Separator, of which the following is a full, clear, and exact description.
This invention relates to improvements in ore-separators, the object being to provide an electromagnetic apparatus for separating from sand or pulverized ores metals of weak magnetic action and the separation of ores of equal specific gravity by a dry process, re sulting in the saving of fine dust generally lost by the present methods.
We will describe an ore-separator embodying our invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of an ore-separator embodying our invention. Fig. 2 is a section on the line 2 2 of Fig. 1, the drum employed being also partly in section. Fig. 3 is a sectional detail showing the electromagnetic poles and the frame or carrier for magnetic material employed, and Fig. 4 is a section on the line 4; 4 of Fig. 3.
Referring to the drawings, 5 designates a magnet-core on which a magnet 6 is wound. This core is supported on a frame or upright 7. The core has arm extensions 8 and 9',"to which the north and south pole magnets 10 and 11 are respectively connected. These magnets 10 and-11 are in connection through the wires 12 and 13 with a dynamo or other source of electricity, and their windings are also in connection with the winding of the magnet 6.
Attached to the north-pole magnet 10 are pole-pieces 14. They may'be rigidly attached or they may be made removable. These polepieces or shoes are made of strips of iron and are projected beyond the magnet in the direction of movement of a drum 15. The drum 15 rotates between the poles of the magnets 10 and 11, and this drum is made of non magnetic material, upon which is mounted a series of bands 16 ofmagnetic material.

Serial No. 59,596. (No model.)
here shown the bands as seated in annular channels or curves formed in the periphery of the drum; but it is to be understood that the bands may be otherwise supported onthe drumthat is, the drum may have a plain or smooth exterior and the inner surfaces of the bands engage tightly thereon. The object of the rings or bands is to create induced magnetic lines of force traveling in the direction .of the revolving drum and to retain the intensified lines of force after leaving the pole By extending the shoes or pole-pieces 11 the magnetic lines of force flow from the magnet and are given off from the high points of the shoes or pole-pieces and thence to the rings of magnetic material on the revolving drum. By rounding the faces of the shoes or pole-pieces the magnetic lines become intensified on the curved surfaces of the polepieces, and if the said pole-pieces are made detachable the concentrated magnetic lines may be increased or diminished at will.
The drum 15 is mounted on a shaft 17, on which is a pulley 18, designed to be engaged by a band leading from a driving-pulley 19, mounted on a swinging frame 20. This driving-pulley 19 is shown as mounted on a shaft 21 in said frame 20, which is below the rocking or pivotal point of said frame. On this shaft 21 for the pulley 19 is a roller 22, around which a belt or conveyer 23 passes. The said belt or conveyer passes around a roller 24:,
' supported in an extension 25 of the frame, and
around a roller 26, supported in an extension 27 of the frame. By employing the swinging frame the carrier belt or band is self-adjusting relatively to the hopper 28, in which the material to be operated upon is placed. The front of this hopper is provided with a valve 29 to regulate the discharge of material through the opening in the front of said hopper.
It will be noted that the belt or band passes over and engages upon the core of the magnet 11, and extended at an incline from a point over the roller 26 is a chute 30, over which the metals discharge into any suitable receptacle. In practice the ore or sand containing metal is fed from the hopper 28 to the band or belt 23 and into the zone of intense magnetic lines of force. The shoes or pole-pieces 14 on the We have ICO upper magnet concentrate the lines on the upper part of the pole-faces of the magnet and cause the particles of magnetic material to be attracted toward the upper magnet and directly onto the shoes or pole-pieces. The revolving drum passing under the shoes prevents the magnetized particles from coming in contact with the shoes, and the magnetic bands on the drum carry the magnetized particles out of the intense magnetic field, where theyare separated from the non-magnetic materials. The magnetic rings or hands also present an intense magnetic field, weakening as they approach the extremities of the shoes or pole-pieces 14. The revolving drum, with the bands of magnetic material, produces, in conjunction with the shoes or pole-pieces, an induced magnetic current, which travels in the direction of the revolving of the drum.
The metals will discharge over the chute 30, while the sand or other non-magnetic material will pass off the band or belt nearthe roller 26.
Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. An electromagnetic ore-separator, comprising opposite electromagnet's, a drum of non-magnetic material movable between the poles of the magnets, projecting pole-pieces on one of the magnets, a carrier movable over the lower magnet, ahopper adjacent to and discharging directly onto said carrier, and bands of magnetic material supported on the drum, substantially as specified.
2. An electromagnetic ore-separator, comprising electromagnets of opposite polarity, a drum of non-magnetic material movable between the poles of the magnets, pole-pieces attached to one of the electromagnets and having ends extended in the direction of rotation of the drum, bands of magnetic material surrounding the drum, and a carrier movable between the magnets, the said carrier being adjustable as to pitch, substantially as specified.
3. An electromagnetic ore-separator, comprising electromagnets of opposite polarity, a revolving drum movable between the poles of the magnets, one of said magnets being arranged within said drum, a series of shoes or pole-pieces attached to said magnet within the drum and having their ends extended beyond the magnet in the direction of rotation of the drum, bands of magnetic material surrounding the drum, a carrier-belt movable between the drum and the lower electromagnet and a swinging frame on which the belt is mounted, substantially as specified.
4. An electromagnetic ore-separator, comprising opposite pole electromagnets, a drum mounted to rotate and within which one of the poles of the magnet is located, the said drum having peripheral channels, bands of magnetic material seated in said channels, a swinging frame, a driving-pulley carried by said frame, rollers on the frame, an endless band passing around said rollers and movable between the electromagnets, and a hopper for discharging material onto said band, substantially as specified.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
