ALEXIS LOT OZKY, OF KHARKOFF, RUSSIA.
APPARATUS FOR MECHANICALLY SEPARA'IING MATERIALS.
To all whom it may concern:
Be it known that I, ALEXIS Lo'roz xY, en-v chanically Separating Materials, of whichv the following is a specification.
The present invention relates to apparatus for the mechanical separation of materials such as coal and rock and the apparatus is constructed and operated on the principle that if two bodies, one having a lesser coeflicient of friction and the other a greater, move on to an inclined surface traveling in its own plane in the opposite direction to the movement of said bodies the body having the lesser coefficient of friction will slip on the inclined surface and continue to move in its original direction while the other body will come to rest on the inclined surface and then be carried back in the opposite direction to its original movement.
The angle of inclination of the inclined surface for the particular materials above mentioned will be selected so that it is greater than the angle of friction for the coal and less than the angle of friction for the rock.
Referring now to the accompanying drawings which illustrate the invention, Figure 1 shows a vertical section of the apparatus, Fig. 2 is an elevation viewed from the right of Fig. 1 and certain parts being in section, and Fig. 3 is a plan view.
A rectangular box a projects into the main casing c to one side of the center thereof and is adapted to slide relatively to said main casing. The mixture of anthracite and rock is fed into the box a through the hopper f and is fed forward, by shaking in a manner hereinafter described, until it falls on to a disk 7) adapted to rotate in the main casing c. There may be several boxes or formed in one piece and a corresponding number of disks 7), three being shown in Fig. 1. The main casing c is connected by suitable means to bearings s, s, Fig. 2', and it may be moved on these bearings, by means of a worm j, to any desired angle. The disks 6 are mounted on a shaft 9 which is driven by bevel gearing 6, e, from a horizontal shaft h co-axial with the axis of the bearings s, s.
The box a is provided at its outer end with a roller is which is maintained in contact with a ratchet-shaped member 71 by means Specification of Letters Patent.
glneer, subject of the Czar of Russia, resid- Patented July if, 1916.
Application filed March 20, 1916. Serial No. 85,317.
of' a spring Z and the compression of said spring is regulated by a hand-wheel m. By rotating the ratchet-member i the box a is glven a shaking motion which causes the mixture of anthracite and-rock to move forward and finally drop on to the inclined surface of the disk or disks 6. The adjustment of the spring Z enables the intensity of the shaklng movement, and therefore the feed, to be controlled. Plates w, w, are provided 1n the hopper f to insure a substantially unlform distribution of the mixture of anthracite and rock into the various boxes a, a, a.
The arrow shown in Fig. 3 indicates the direction in which the disks 6 revolve which is such that the materials fall on to an inclined surface -moving upwardly in its own plane. The anthracite is discharged through the opening or chute (Z and the rock through the opening or chute r. The distance between the surfaces of the disks and the boxes or are varied according to the nature of the materials to be separated.
What I claim is:
1. Apparatus for the separation of materials having diflerent coefficients of friction comprising a frictionally retarding separating disk inclined at an angle intermediate of the angles of rest of the materials being separated, means for rotating said disk, a feeding shelf extending over, and substantially parallel to, said disk at one side of its axis, said shelf terminating intermediate the highest and lowest portions of said disk and spaced sufliciently above the same to permit passage thereunder of one of the materials being separated, and means for shaking said shelf in its own plane.
- 2. Apparatus for the separation of materials having different coefficients of friction comprising a frictionally retarding separating disk inclined at an angle intermediate of the angles of rest of the materials being separated, means for rotating said disk, a feeding shelf extending over, and substantially parallel to, said disk at one side of its axis, said shelf terminating intermediate the highest and lowest portions of said disk and spaced sufliciently above the same to permit passage thereunder of one of the materials being separated, means for shaking said shelf in its own plane, and means for adjusting the angle of inclination of the disk and shelf simultaneously' 3. Apparatus for the separation of madiate the highest and lowest portions of said disk and spaced sufliciently above the same to permit passage thereunder of one of the materials being separated, means for shaking said shelf in its own plane, and means for varying the intensity of the shaking motion.
4. Apparatus for the separation of ma terials having different coefficients of friction comprising a frictionally retarding separating disk lncll-ned at an angle intermediate of the angles of rest of the materials being separated, means for rotating said disk,
a feeding shelf extending over said disk at one side of its axis, said shelf terminating intermediate the highest and lowest portions of said disk and spaced sufficiently above the same to permit passage thereunder of one of the materials being separated, means for shaking said shelf longitudinally in its own plane, means for varying the intensityof the shaking motion, and means for usting the angle of inclination of the disk and shelf simultaneously.
In testimony whereof I affix my signature in presence of two witnesses.
