APPARATUS FOR SEPARATING PARTICLES OF METALLIC 0R MINERAL-BEARING SUBSTANCES OF DIFFERENT SPECIFIC GRAVITY.

SPECIFICATION forming part of Letters Patent No. 444,613, dated January 13, 1891.

Application filed May 10, 1889.

To-ctZZ whom it may concern:

Be it known that I, ORRIN B. PEOK, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Apparatus for Separating Particles of Metallic or Mineral-Bearing Substances of Different Degrees of Specific Gravity, of which the following is a specification.

The object of my invention is to make an apparatus for use in separating the particles of different metallic or metal-bearing substances either from each other or from the materials or ores with which they may be combined where the particles are of different specific gravities and without first reducing such substances to a molten condition; and my invention consists in the features and details of construction hereinafter described and claimed. g

In the drawings, Figure 1 shows a transverse vertical section of my improved apparatus, and Fig. 2 shows a plan view of the same.

In making the receiving-vessel as I prefer to make it the walls flare or slant outwardly from the bottom toward the top. The top is provided with a rim or cover which extends out a short distance from the sides, so as to catch the material under the same. The balance of the top of the receiving-vessel is left open.

The material intended to be treated in the receiving-vessel consists of ores or metalbearing substances reduced to a fine or powdery condition, so as to consist of very minute particles.

To prevent the material treated from packing or caking against the sides of the receiving-vessel, I provide a stirrer or agitator B, having an arm C, preferably screw-threaded and passing through suitable bearings and through the screw-threaded hub of a sprocketwheel D, which is intended to be rotated by a sprocket-chain or other suitable means. By the rotation of the sprocket-wheel slowly in one direction or the other the agitator or stirrer can be adjusted in or out from or toward the walls of the receiving-vessel. I prefer also to provide the agitator or stirrer with Serial No. 310,274. (No model.)

small pins or fingers I), screwed into its side next to the walls of the receiving-vessel. Where they are screwed in they may be easily removed as they become Worn and new ones inserted in their places. These pins or fingers extending toward the walls of the receiving-vessel serve to stir and agitate the material as it settles against the same, and thuskeep it constantly in a condition adapted to the movement of the heavier particles through the material toward the outside as driven by centrifugal force. By adjusting the parts in a proper way the fingers b may be gradually carried out from the walls or sides of the receiving-vessel, permitting an accumulating thickness of the heavier particles of the material treated to be retained or held by centrifugal force against the sides or walls of the receiving-vessel.

In order to remove the lighter particles of the material treated, instead of permitting them to fly off at a tangent at the top, I prefer to employ a cutter or scoop E, adjustable with the agitator or stirrer toward or from the walls of the receiving-vessel, so that as the fingers of the stirrer permit a thicker bed of material to settle against the sides of the receiving-vessel the cutter or scoop will also permit the same by moving away from the walls at the same rate that the stirrer or agitator moves. To secure this end I prefer to arrange the cutter or scoop on an arm F of the agitator or stirrer, so that it will be adjustable by the same means that are used to adjust the agitator or stirrer. Of course the cutter or scoop might be adjusted on independent means, although I prefer to use one means of adjustment for both. The operative end of the cutter or scoop is arranged at an angle with the sides of the receiving-vessel and opens against the direction of rotation, so that as the material is carried around with the receiving-vessel the particles revolving at the proper distance from the sides will be caught by the cutter or scoop and carried through the same to be deposited in an annular trough G or any other suitable receptacle that may be provided.

As in some cases it is desirable to wash or dilute the material treated with water while in the revolving receiving-vessel, I provide a pipe H, that is connected with a tank or other water-supply, so that by opening a cock water may be admitted into the receiving-vessel. I prefer to direct the end of the pipe II toward one of the sides of the receiving-vessel, so that as the water rushes out of the same it will strike against the side of the vessel at an angle, so as to exert a stirring or agitating effect, as well as to dilute and wash the material treated.

What I regard as new, and desire to secure by Letters Patent, is

In an apparatus for separating particles of dilferent degrees of specific gravity contained in metallic or metal-bearing substances, the combination of a revoluble receiving-vessel adapted to receive the material to be treated ORRIN B. PEGK.
