ORE-CONCENT RATOR.

SPECIFICATION forming part of Letters Patent No. 270,956, dated January 23, 1883.

Application filed July 10, 1382. (No model.)

Zo all whom fit mag/.concern Be itknown that I, CHARLES KLEINscnMID'r,

of Breckenridge, in the county of Summit and State of Colorado, have invented certain new and useful Improvements in Ore-Concentrators; and I do hereby declare the following to be aptull, clear, and exact description of the invention, such as will enable, others skilled in the art to which it pertainQ'to make and use ro the same.

My invention relates to ore separators or concentrators; and it consists in the peculiar construction of the same, as will be hereinafter fully set forth and claimed.

In the drawings, Figurel is an isometric view of an ore-separator embodying my invention. Fig. 2 is a longitudinal vertical section taken through the same. Fig. 3 is adetached sectional view of one of the parts of my de- 2o vice, showing more clearly its construction.

A is the frame ot' my machine.

B is an adjustable frame-work, iu which are journaled three large rollers, G D E, and a series of smaller ones, a a and a. This frame B is so placed in the frame A as to incline toward one side,.as shown in Fig. 1.

F is an endless apron or belt, which is mounted on the rollers C, D, and E, and supported by the -smaller rollers, a a and a', in such 3o a manner as to cause it to present an inclined upper surface, running horizontally from one end of the frame A to the other end, and to cause that part of its lower side which runs over the roller E to be depressed, as shown in h3,5 Fig. 2.

G is a pan or water-trough occupying a position directly under the roller E, so as to cause the belt which is'depressed at this point to pass through the water contained in said pan 4o or trough.

H is awater-pipe, which is supplied with a series of branch pipes, b b and b. The branch pipes b b are so located as to cause jets of water toissue from their ends onto the apron F 4 5 at different points, and the branch pipe b is located over the feed-'chute I, by means of which the ore is fed onto the apron or belt. The belt F is adapted to move from one end ot' the frame A to the other, it being driven by one of the rollers, C, to which rotary motion is commu- 5o nicated in any suitable manner, one manner being shown, which consists of a belt, c, which is driven from the shaft d, said shaft being in turn driven by another belt., e, which is driven from the shaft j'. This shaftf is driven by 55 any suitable power. The shaft f is provided with an eccentric or crank, g, by means of which a reciprocating motion is given to the frame B and belt F through the pivoted lever h. (See Fig. 3.) The incline of the frame B 6o and belt F may be adjusted by means of the hanger-rods i and j j, which are provided at their upper ends with screw threads and thumb-nuts i t" and j j.

K is a chute located at thelower edge ofthe belt F. This chute isin such a position as to receive the dirt and impurities as they are washed from the ore and allow them to fall outside of the machine. I may provide this chute with a suitable number of switches, k lc 7o k, by means of which the different grades of waste rock or tailings are kept separate, and thus the more valuable part of said tailings may be worked over again.

The operation of my device is as follows: The machine being set in motion, the belt F is driven from the right toward the left, and also reciprocated by means of the crank g on the shaft f. The ore, being fed on the belt at the right through `the chute I, is carried toward 8o the left, and as it is being carried the jets of water issuing from the brauch pipes b b act to separate the lighter rocks and impurities therefrom, thelighter of theseimpurities being separated rst and passing oli" from the belt F and onto the lirst section to the right of the chute K, and from thence off into a suitable receptacle or onto the ground, and the next heavier passing oft' the belt onto the second section of the chute K, and so on, each grade of impu- 9o I rities being, as far as practical, separated into a pile by itself. The heavier ore or metal is carried by the belt F into the water in the trough G, where it is washed oft' from the belt and falls to thebottom of the said trough.

What I claim is- The combination, with a transversely-inclined reciprocating frame having rollers mounted therein, :t discharge-chute attached to this specification in the presence of two to the frame,and switches connected with said subscribing Witnesses.

chute of an endless belt for receiving and carw ryingthe ore, mounted 0n said rollers, and de- CHARLES KLEINSGHMIDT 5 vices for imparting movement to said belt, sub- Witnesses:

stantial'ly as set forth. SAMUEL C. VVHIPPLE7 In testimony whereofIhaVe signed my naine CHRISTOPHER C. ACTON.
