ORE-SEPARATO R.

sPEoIFIcATIoN forming part of Letters Patent No. 485,962, dated November e,- 189e.l 1f l Application tied october 27,1890. serial 110.369,469. (Numan.) Patented in Germany-Apel 2s, las?. No. 41,599, attain Austria-Hungary July l, 1887, No. 26,502 and No. 61.312. l 'i T0 all whom, it may concern,.-

Be it known that I, CARL AUGUST EMIL MEINICKE, a subject of the King of Prussia, residing at Clausthal, in the Kingdom of Prussia, Germany, have invented new and useful Improvements in Ore-Separators, (for which' I have obtained Letters Patent in Germany, No. 41,599, dated April 28, 1887, and in .cal longitudinal section of the apparatus. Fig. 2is a plan; and Fig.3 is a detail section on line 1 1 of Fig. 1 through one of the partitions, the channel d being shown i-n dotted lines m n o p.

A is a supply-chute discharging into a hopper a, and A' is the ofttake-chute at the opposite end of the hopper and in alower plane than the chute A. Below the hopper a is a casing B, having a vertically-extending zigzag channel c, at one side of which is formed aseries of chambers f f2 f3 f4, provided with water-inlet valves h h2 h3 h4, and communieating at their inner ends with the said channel c by means of passages e e2 e3 c4. The opposite side of the casing B is provided with a series of upwardly and outwardly inclined channels d', d2, d3, d4, and d5, communicating at their lower ends with the vertical channel c, and at their upper ends the channels d d? d3 d4 lead into chambers K over plates k. The chambers K at one side of their lower portions are provided with lateral outlet-pipes d dsc d20 cl, having ordinary rotary slidevalves d". The channel c may be closed or partially closed at the lower ends of the channels d2 to d4 by means of slides s2 s3 s, carried by rods S5, extending up through the said channels and provided at their upper ends with adjusting-nuts s6. At the upper end of upper edge of which thewastev`wateryiiow`s also be adjusted rod and nut.

'lheoperation is as follows: 'lhe ground ore or mud is fed from the chute Ainto the hopper @,and passes thence through the opening b into the upper end of channel c, where it meets the ascending current ot water from one or all of the cham bers f to f4,which causes the light worthless matter to rise with the water, passing up through the channel d5 to the oltake-chute A. The heaviest ore particles will descend to the bottom of the channel c and be carried up through the channel d. and out through pipe (ZO into any suitable receptacle, and so with the other ore particles, which will pass through the other channels (Z2 to d4 in like manner. If the force up or down by means of'a into the outlet-chute A', and this gate may of water through the chamber f is insuflil cient, then one or more of the valves h2 to h4 may be opened, as will be readily understood.

IE the materials being treated so require, one or more of the .chambers -f and corresponding channel d may be cut out by closing the channel c by means of the proper slide d2, dto., whereupon only the channels above such slide will be operative.

Should it be found that any light ore partimay be raised a little higher, vent such action. will be collected in suitable receptacles placed under the outlet-pipes d d4".

Having thus described my invention, what I claim is- 1. An ore separator and grader comprising the hopper, a casing thereunder provided with a vertically-extending channel c,.communi cat-ing with the outlet in the bottom of said hopper, a series of valved water-supply chambers at one side of the said channel communicating therewith, and a series of separate and independent channels leading upward and outward from the channel c to separate outlets, substantially as set forth.

2. Thecombination, in an ore separator and grader, with the hopper having an opening in which will preits bottom, of the casing under the hopper, provided with a vertically-extending channel cles are passing over the gate d50, said gate The graded concentrates IOO e- Y l 485,962

c, awater-inlet at the bottom of the casing to cause an. upward flow through channelrc against` the downward ow through the hopper-opening, a waste-channel leading upward and outwardf rom the upper end of channel c,

and a; series. of'separate and independent giadingchanne1sy leading upward andout- Y ward fromathe bottom and between the endsv of the channel-c to separate outlets, substan-f tiallyvasset forth.
