SPECIFICATION forming part of Letters Patent No. 473,451, dated April 26, 1892.

Application filed May 14:, 1891. Serial No. 392,671. (No model.)

To aZZ whom it may concern:

Be it known that I, GUs'rAvIs LORRIMER OUDNER, a citizen of the United States, and a resident of New York, in the county of New 5 York and State of New York, have invented certain new and useful Improvements in Placer Disintegrators and Amalgamators, of which the following is a specification.

My invention relates to an improvementin IO machines for treating placer and ores carrying precious metals.

The chief object of my invention is to bring the placer or crushed ore in contact with agi-- tating chain cables, which constantly triturate I 5 the ores by carrying them in an inclined upward position, and then letting them fall to the bottom of the machine to be again carried upward by the chain cables, during all of which time the ore and pebbles or substitutes 2o for pebbles are being acted upon by coming in constant contact with each other and thusbeing separated, and the metallic parts, being released, are carried by gravitation to the bottom of the machine by either being thrown 2 5 back into the mass of the matter under trituration and coming in contact with the mercury provided for that purpose in the bottom of the machine or falling through the perforated plate or screen and carried downward into the mercury, while the released fine particles of debris held in suspension in the water are carried out of the machine by way of the outlet-chamber G, and from thence onto a concentrator, which is provided for the purpose of catching and holding such parts of the metallic matter that may not have been amalgamated by the mercury in the bottom of the machine.

By means of the machine devised by me I am enabled to successfully and profitably treat ore placers and placer tailings and ores and ore-tailings carrying a very small percentage of precious metal.

In the drawings, Figure 1 is a front elevation. Fig. 2 isa cross-section on the line X X of Fig.1. Fig. 3 is alongitudinal section on the line Y Y of Fig. 2. Fig. 4 is a top view. Fig; 5 is a rear view showing back of plate and thimbles. Fig. 6 is a modification of the top of the back plate B.

Like letters represent like parts.

A represents the body of the machine,which is a trough of a triangular shape and is supported on four stanchions or posts. This body can be made of any suitable material; but I prefer to build it of metal plates fastened in I which runs from end to end of the trough A.

and is suitably fixed. The space between the nearly perpendicular front wall of trough A and the partition E is a discharge-chamber and is designated G.

D is'a second partition running from end to end of the trough A on a line with the outer front wall thereof, extending downwardly to a point where it almost meets the chain J. The space between the partitions E and D is an inlet-chamber and is designated as chamber F, and into which the material is dumped.

To the back of the partition D and running from end to end is fixed a perforated gutter M, which is provided for the purpose of carrying off the pebbles and other large matter which is discharged continuously, the discharge of the pebbles and coarse matter being assisted by the rake N, which is oscillated by means of a cam-wheel and drivingpulley WV, as shown in Fig. 1, thus throwing the discharged matter off the gutter at either end.

B is a perforated plate or screen set at an angle of about thirty degrees and slopes backwardly and meets plate I near its top, which plate I is provided with the eyelets or thimbles z' i at its upper end, and through which the cable-chains J pass. At the rear top end of the trough and properly boxed in the stanchions is set a shaft, upon which are fixed at regular intervals grooved pulleys II. To one end of the shaft is attach ed a pulley to rotate the shaft.

J J are cable-chains, which run over the pulleys H and under and around and up through the eyelets of the guide-bar O.

L is a perforated water-pipe running from end to end of the trough Aat or near the gutter M.

L is a perforated water-pipe running from end to end of the trough in the chamber G a little above the guide-bar O. L is another perforated Water-pipe running from end to end of the trough at or near its extreme bottom and opposite the clean-u p discharge-opening Q, with the perforations toward the plate K. The front Wall of the trough is provided near the bottom with an opening, through which the machine is cleaned up, to do which it is only necessary to remove the elasticbacked plate K, which is held in place by a number of clamps K, provided with lever screw-bolts.

Running along the front wall, but at a point some inches below the line of the gutter M, is provided a discharge-spout G A is a suitable hopper set over the charging-chamber F and facilitates the introduction of the material to be treated; but this hopper may be dispensed with.

When in operation, I proceed as follows: The water being turned on the pipes L, &c., the ore to be treated is introduced into the charging-chamber F and is carried downward in the line indicated by the arrows. The material there meets the chains J, which, running in an upward direction, as shown by the arrow, over the pulley, the pebbles and ores and other matter come into constant friction with each other, and thus the clayed particles and such parts as may adhere to the pebbles are divorced from each other and the whole mass is thoroughly separated and the metallic parts separated from their foreign coatings and adherents. The Whole mass is constantly whirled about, being carried up the inclined perforated plate or screen to a certain point near the top and gradually accumulated against the partition E, until by constant addition to the mass being triturated or separated the dbris is thrown up into the gutter M and removed by the action of the rake N. During the time that the mass is being agitated or tumbled by the upward action of chains J J a sufficient quantity of quicksilver will be added, which by gravitation mostly settles at the bottom of the trough A. The precious metal separated from the ore is partly carried directly to'the bottom by gravity and partly through the action of the Water through the perforated plate or screen to the bottom of the trough A, where it again comes in contact .under the guide-bar O and through the mass of mercury, the earthy parts held in suspension by the rise of the water are carried up through the discharge-chamber G and out over the spout, where it is preferably carried onto a concentrator, which is intended,as far as possible, to catch the metallic particles that have no affinity for quicksilver and the particles of concentrates not caught in the mercury in the trough. For this purpose I have constructed a peculiar concentrating mechanism, which will be the subject of an application for a patent hereinafter.

I may-now state that in some cases Where the precious metal is on hand in a coarse state it is not necessary to use mercury, the metal being carried to the bottom by gravitation. -In some cases where the matter to be treated is finely-pulverized, stamped, or crushed ore I throw into the trough a quantity of metal pieces of any shape or a quantity of pebbles, which assist in the separationby reason of friction. This may also be done to advantage in placer ores that carry little gravel. By the use of this machine I have in practice been enabled to capture the finestfloat-gold and the largest per cent. of value. The chains J J pass through the thimbles t' i of the plate I, and thus the small pebbles that may ascend some distance over the level of the water by clinging to the chains cannot fall between the chains and the throat and clog the action of the machine. The mass in the main chamber of the trough stands nearly level with the top and considerably higher than at the spout G In cleaning up it is only necessary to remove the plank K and draw the charge of amalgam or the metal that may have lodged there.

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

1. In an ore separator or amalgamator, the combination, with a trough, of an inclined perforated partition therein, a shaft above it, a series of endless chains extending both sides of said partition and over the shaft, and means for rotating the shaft, substantially as described.
