MACHIN-E FOR EXTRACTING GOLD FROM PULVERIZED ORES,&.C.

SPECIFICATION forming part of Letters Patent No. 478,971, dated J'uly 12, 1892.

` Application filed May 16, 1891. Serial No. 392.970. (No model.)

' Gold from Pulverized Ores and Gold from Auriferous Sands and Gravels, of which the following is a specification.

My improvements relate to a class of machines for this purpose shown and described in Letters Patents of the United States issued June 23, 1885, and November 3, 1885, and numbered 320,655 and 329,832, respectively, the first granted to Jacob L. Hayward and the second to Jacob L. Hayward, Thomas O. Simonton, and Thomas O. Simonton, Jr., and to such other machines of like kind wherein up- 'ward currents of water are forced through a body of water confined in a tank lined with amalgamated plates to carry the material being treated from the time it is fed into the machine until discharged to the Asurface of the water and there allow it to gravitate and come in contact with the said amalgamated plates. In these machines, and especially in the two embraced in the said two Letters Patent, there is a mercury-receptacle, (and in some there may be more than one,) which is separated from the main body of the tank or the bottom of it. Into this mercury-receptacle the surplus mercury fed upon the amalgamated plates lining the machine runs and carries with it more or less gold. I have found from actual experience that not only the surplus mercury but a great deal of the pulverized ore or the sand and gravel being treated and passed through the tank also nds its way into these receptacles and mixes with the mercury, closes up the openings from the tank into the mercury-receptacle, and prevents the `mercury from running in, and also closes the receptacle up entirely, and thus a great deal of the mercury is lost and with it whatever gold it contains.

My invention therefore consists in overcoming this difficulty, which I do and attain by the introduction of a current or currents cury receptacle or receptacles of such machines, and the water so forced into the mercury receptacle or receptacles produces a current from the receptacle out into the main body of the tank, and while itis not of sufficient force to prevent the mercury from passing from the amalgamated plates or the main tank, does prevent the ore, gravel, or sand being treated, being of less specific gravity, from passing into the receptacle or receptacles and from closing up or lodging in the 6o openings from the main tank to them.

For the purpose of illustrating my invention I show the same as adapted and applied to the machines shown and covered by the two Letters Patent above referred to; but I do not confine my invention to these machines. Iattain the objects named by the mechanism illustrated in the accompanying drawings, in which- Figure lis alongitudinal section of the ma- 7o chine, showing only one valley. Fig. 2 is a cross-section of the same near the tailingstank, showing the main tank divided into two longitudinal valleys and two bottoms and showing the openings into the tai1ings-tank. 75

Like numbers refer to like parts throughout the views.

l represents the tank; 2, the amalgamated plates lining the inside of the tank. 3 are the water-supplypipes. Ltare thejet-nozzleson the 8o supply-pipes. 5 are the longitudinal spaces or openings from the tank above into the mercury-receptacles Gbelow. 7 are the T-nozzles on the under side of the supply-pipes 3. 8 are the agitators. 9 are the openings from the 85 main into the tailings-tank. l0 is the drawoff cock for the mercury.

The mode of operating these machines, eX- cept so far as relates to my improvements,is well known and is described in the Letters 9o Patent above referred to My said improvements consist, as I have above stated, in introducing Water under pressure into the mercury receptacle or receptacles, and this, as shown in the drawings, is done through the T pipe or nozzles 7 on the under side of the supply-pipes 3, and the reason I show and pre- Yfer to use a'T pipe or nozzle is to distribute the force of the water and to keep the currents from striking the bottom of the receproo tacle and louring the mercury that may be there. The water to run the machine and carry the gravel, sand, or other material to be treated is fed under pressure into the machine through the supply-pipes 3 and jet-nozzles 4;, and that used to create the pressure in the mercury-receptacles 6 is fed therein through the T-nozzles 7, and the water so introduced into the mercury-receptacles produces an upward current, as indicated by the arrows in the drawings, through the spaces 5 into the tank above, for the purposes set forth above.

I do not confine myself to any particular manner of introducing the water under pressure into the mercury-receptacle for the purpose aforesaid. That shown in the drawings is the most convenient mode, but the Water may be introduced by means of a separate pipe or pipes.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a machine for extracting gold and silver and lined with amalgamated plates, the combination of a supply pipe or pipes having a series of j et-nozzles on the upperside of the pipe attached thereto, and such pipe or pipes running through the tank longitudinally at or near the bottom thereof, with a mercury receptacle or receptacles partly separated from the main tank and supplied with a pipe or pipes through which Water may be forced, for the purposes above set forth.

2. The combination of tank l, lined with amalgamated plates 2 and having supplypipes 3 running longitudinally along the valley or valleys of the tank and having j et-noz zles 4 on the upper surface and agitators S between the jet-nozzles 4 with the mercury-rcceptacles G, provided with T-nozzles 7 and connected with tank l through spaces 5, substantially as and for the purposes above set forth.

3. In a machine for extracting gold from auriferous ores, a tank lined with amalgamated plates and having a longitudinal angular bottom or bottoms and having a supplypipe in each bottom, upon the upper surface of each of which is a row of diagonal j et-nozzles, between which latter are agitators, in combination with a mercury-receptacle in the bottom of the tank, connected therewith by slight openings and having a pipe or pipes connected with the said mercury-receptacle for the supplying of Water therein under pressure, substantially for the purposes above set forth.

4. In a machine for extracting gold and lined with amalgam-ated plates, the combination of a mercury-receptacle having connected therewith a pipe or pipes through which water may be introduced therein with a tank lined with amalgamated plates and said tank connected with the mercury-receptacle through spaces or openings, substantially for the purposes hereinabove set forth.

5. In an ainalganiating-machine the tank of which is lined with amalgamated plates, the combination of a supply pipe or pipes having upon its or their upper surfaces a row of diagonal jet-nozzles and upon its or their under surface a series of jet-nozzles with a mercury-receptacle connected with the main tank by small openings, substantially for the purposes above set forth.
