UNITED STATES PATENT OFFICE.
GRIFFITH MORGAN ELDRIDGE, OF PHILDELPHIA, PENNSYLVANIA.
ORE WASHR AND CONCENTRATOR.
:SPECIFICATIN forming part of Letters Patent No. 502,663, dated August 1, 1893.
Application filed April 14 1893. Serial No. 47 ,27 (N m l T0 all whom it may conccrn:
Be it known that I, GRIFFITH MORGAN ELDRIDGE, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State'of Pennsylvania, have invented certain new and useful Improvements in 0re Washers and Concentrators, of which the following is a specification, reference being had therein to the accompanying drawings. A
'My invention relates to an improvement npon au 0re washer and concentrator patented to Charles F. Pike September 1, 1891, No.458,837, and it consists in a device whereby a defect in that machine is obviated and the gangue is Well agitated without interfering With its separation from the 0re.
Referring to the aocompanying drawings: Figure 1. is a sectional elevation of a washer or concentrator showing details of construction, as in the Pike machine, and also the improvement which I have made therein. Figs. 2. and 3. are det-ails of a pipe for agitacing the gangue, with single and double nozzle. Fig. 4. is a detail of the perforations in the bottom of the reoeiver. Fig. 5 is a seqtional bottom plan view taken below the plane of dotted lino Fig. 1.
A. represents a feed box having an inolined grating or analogous surface leading to a discharge end a, said box having an open botton a below the grating a. From the bottom a leads a chute pipe 1), which enters and depends into near the bottom of a preferably open-top cylindrical receiver B, which is supported in any suitable manner, as indicated at 1), upon au outside jacket or chamber 0, so as to admit of its being rotated by a band, chain or belt b suitably applied and driven, the actuaring or power-transmittingdevice for said belt I) not being shown in the drawings, as they are obvious.
At or near the top of the chamber 0 is a water supply pipe D. and at the bottom of said chamber is a valve d of any suitable or desired construction t0 admit of drawing ofi from time to cime of any accumulations of ore in chamber C through outlet pipe et.
The bottom of the receiver B may be constructed as shown in solid limes, or as in dotted lines Z) or otherwise as desired. Depend ing into the receiver B is a pipe E, which 7 ter.
preferably has an outwardly-flaring or inverted-funnel-shaped lower end 6 for embracing the bottom I) of the receiver B. This pipe E connects, preferably by a slip-joint 6, with the inlet-pipe f of a suction or sand pump F of the kind which admits of the passage through it of a large bulk or volume of material, the same being a valveless or centrifugalpump,commerciallytermedamal-pump. It discharges onto G, which may be a wastegrating or sluice or may lead to another concentraior, as may be desired.
The operaci0n is as follows: The gangue, With its bowlders, stones or other bnlky matter, as contradistinguished from prepared or pulverized gangue, is dumped or supphed to the grating awhich separates from the gangue the bowlders or other large waste materral. Preferably a stream of water is supplred to the grating a in any suitable manner, as by an independent pipe or by a branchf from the discharge end f of the pump. The screenings from the grating a are conveyed by the chute-pipe b into the bottom of the receiver B, where they are subjected to the upward flow or current of water from supplypipe D. throngh chamber C, and up through the perforations in the bottom b of the reoeiver B, and to other water current hereinafter specified, whereby the 0re is separated from the gangue and brought to the bottom of the receiver and whence it falls through the perforations in said bottom to the bottom of the jacket or chamber 0, from which it may from time to-time be drawn off by opening the valve in outlet-pipe d.
-The machine, as thus far'described, is the Pike machine, in which the water supplventers only into the space between -the rece1ver 'B and chamber C, (except that which cornes through'i chute b,) passing up through the perforations in the bottom of the rece1ver B, and thus agitating the gangue, while -the ore'passes, or should pass down through the same perforations against the current of wa- The defect of this machine is that With suoh current of water passing up through these perforations as is necessary sufficiently t0 agitate the gangue the particles of ore which it is desired to have pass down through these perforations are held up by the current of water and Will not so pass down; at least to such of them as are of small size or irregular shape; and it is this defect Which my invention is intended to remove. To this and I continue the connection of the pipe D to the ehamber 0. but With only a light pressure of water; and I furnish the reeeiver B a further supply of water by a pipe H, whioh enters and depends into the receiver near to its bottom and terminates in one or more nozzles H, (shown in detail in Figs. 2 and 3,) preferably inclining horizontally or below the horizontal, and preferably directed against the direction of motion of thereceiver. There may be as many of these pipes H as may be desired.
The cnrrent of water projected from the nozzle of the pipe H is sharp and efieotually stirs up the gangue, oausing and allowing the larger and lighter portions of it to go to the top, and thesmaller and heavier to the hottom, and keeping it in such loose condition as to be readily amenable to the action of the upward current of water in the pipe E- while not interfering with the descent of the 0re through the perforations in the bottom of the receiver. These perforations are tapering, larger at the bottom than at the top, s0
that no 0re can iodge in them, as shown in Fig. 4. The pressure of water in the space between receiver B and chamber 0 is only suficient to prevent accumulation of gangue and ore at the tops of these perforations but not sufiicient to make a ourrent which will interfere With the free passage of the 0re ber to a point immediately above the perforated bottom, the eombination therewith of a pipe adapted to reoeive a current of water and having a nozzle adapted to project a stream of water into said ohamber above the perforated bottom.
2. In an 0re concentrator and washer having a receiving chamber with a perforated bottom or partition and a pump with a suction-pipe projecting into said chamber to a point immediately above the perforated bottom the combination therewith of a pipe adapted to reoeive a current of water and having a nozzle adapted to project a stream of water into said chamber above the perforated bottom.
3. In an 0re washing or concentrating apparatus having a rotating perforated receiver and a pnmp having asuction-pipe projeoting into said receiver the combination therewith of a pipe adapted to receive a ourrent of water and having a nozzle adapted to project a stream of water into said receiver in a direo tion opposite to the direction of motion of the receiver.
4. In an ore washer and concentrator having a rotating reoeiving chamber with a perforated bottom or partition and a pump with a suotion pipe projecting into said chamber to a point above the perforated bottom, the combination of a pipe adapted to receive a current of water and having a nozzle adapted to project a stream of water into said chamber above the perforatedbottom in a direction opposed to the direction of rotation of the chamber and perforations in said bottom or partition tapering from the bottom to the top thereot.
