THOMAS J. LOVETI, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGN- MENTS, JERSEY.
TO THE INTERNATIONAL ORE SEPARATING COMPANY, OF NEW MAG N ETIC SEPARATO R.
SPECIFICATION forming part of Letters Patent No. 486,879, dated November 29, 1892, Application filed February 13, 1892. Serial No. 21,429. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS J. LOVETT, a citizen of theUnited States, residing at Chicago, in the county of Cook and State of Illi- 5 nois, have invented certain certain new and useful Improvement in Magnetic Ore-Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to that class of magnetic separators in which an endless belt runs over a drum, within which there is a rotating I magnet. In large machines it would become necessary to drive an ordinary two-pole ma net at a very high speed in order to secure the necessary number of reversals of polarity, and the magnet would also become large and unwieldy. To avoid this I employ a wheel with a number of small magnets in its periphery. These magnets alternately present their north and south poles at the outer surface of the wheel.
In the drawings, Figure 1 is a section through the main frame, showing the working parts of my invention in side elevation. Fig. 2 is a diagram of the electrical connections. Fig. 3 is a central section through wheel and drum. Fig. 4 is a section through the drum, showing the wheel anda portion of the belt in side elevation.
In all the figures the same part is represented by the same reference-figure.
1 is the main frame, in which are journaled the drum 2 and the idler-pulley 3. The endless belt 4 runs over these. Within the drum 2 and revolving upon the same axis is the wheel 5, containing a plurality of magnets 12, set in its periphery. The inclined feedchute 6 is arranged tangentially to the drum and magnetic wheel. The shaking table 7 is mounted on the shaft 8 and vibrated by the arm 9,which rests on the pins 10, set in the disk 5 11, which forms one end of the drum 2. The
which consists of the disks 13 14, keyed to the sets of four each, with each set connected in series by wires 26 and supplied with current by leadingin wires 25 and 27 from the collecting-rings 21 22.
In operating niy invention a much more rapid rate of rotation is given to the magnetic Wheel than to the drum and to the belt which runs on the drum. This isindicated by the gear 18 being of much less diameter than gear 17. Consequently a line of particles going up on the belt 2 are first subjected to the action of one of the magnets 12, which presents its north pole, and then to the action of the next magnet, which presents its south pole, and so the stulf is subjected to rapid magnetic changes, which keep it continuously 8o alive. The vibration of the shaking table 7 keeps a steady supply of crushed ore going into the feed-chute 6.
Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is
In a magnetic separator, the combination of a wheel which has a plurality of magnets set in its periphery with alternate north and south poles pointing outward, a drum which surrounds said wheel, an idler-pulley, an endless belt which runs around said pulley and drum, mechanism for rotating said Wheel and drum at different rates of speed, and an inclined feed-chute arranged tangentially to 5 said wheel and drum, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
THOMAS J. LOVETT.
