AMALGAMATOR.

SPECIFICATION forming part of Letters Patent No. 304,765, dated September 9, 1884.

Application filed June 25, 1884.

T0 aZZ whom it, 'may concern.- 4 Be it known that I, SIMEON TRUBY, a citizen of the United States, residing at Alma, in the county of Park and State ot' Colorado, have invented a new and useful Amalgamator, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention has relation to amalgama, tors for amalgamating, concentrating, and separating the gangue from eomminuted mineral; and it has for its object to produce a machine of the class above referred to that shall possess advantages in point of simplicity, cheapness, durability, and general etliciency; and the invention consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims. y

Figure l is a view in perspective of a ma. chine embodying my improvements. Fig. 2 is avertical longitudinal sectional view. Fig. 3 is a vertical transverse sectional view, and Fig. 4 is a plan view of thc coneentrator and the slimes-table.

Referring by letter to the accompanying` drawings, A designates the sleepers, and B the track-rails, of the iron track for the concentrator, and C designates the track for the slimes-table. Y

D designates the oreconcentrator, which consists of a frame ot wood mounted on iron wheels E, which run on the track rails B when the concentrator is operated. The frame D is three feet wide and eleven feet long, and inclines from the head to the tail, as shown. The bottoni of the concentrator is composed of one copper plate, E', of the shape shown, and three ironV plates three feet square, having their lower edges lapping the upper edges of the plates next below each,which produces an offset or ritlie at each lap equal in height to the thicknessof the plate,which is about onefourth inch. At the lower edge of the copper plate E', on which the Vamalgamation is performed, is a iine screen, F, which prevents any coarse material from running onto the iron plates G H I below. The tail end of the frame D inclines from the sides to the middle, and is provided with a discharge-opening, J. The central beam, D, of the frame is provided near its upper end with a shoulder, K, which is bifurcated in its end, and is provided with 4end of a wooden spring, T, is entered. spring T is secured at its upper end to the (No model.)

a metal friction-roller, L, against which the operating-cam M on the shaft N strikes to drive the frame D forward on the track. This shaft N has its bearings in boxes O on the sleepers of the track, and is provided with a cone-pulley, P. At the head of the track I provide a stop, Q, against which the cushion R on the end of the central beam, D,whicl1 forms the bumper of the machine, strikes when the concentrator is in operation. The tail end of the frame D is provided with bracket S, in which the lower This iioor or joist above, and is provided with an iron bench-screw, U, for tightening up or loosening the spring as the different ores may require. Then the cani drives the concentrator forward, the spring T returns it, and it is thus given a reciproeatin g motion. A double sluice-box, V, is provided in its main portion with a iine screenV, through which the iiner sands, 85e., pass into the branch portion YW, while the coarser material passes over and upon the slimestable. The sluice-boxV is divided for a portion of its length bya horizontal partition, as shown in Fig. 2, and the branch pori tion 72 extends from the lower passage in said sluice-box.

The slimes-table X is of the same construction as the concentrator with two exceptions: the plates are to be all of iron, and four feet wide. This table will be eleven feet long, but withoutthe copper plate and screen.

The crushed ore is carried from the stampmill in small sluice-boxes, the ore being iirst mixed with water, and water ilowed through said sluice-boxes to carry it to the amalgamator and concentrator, and deposited on the copper plate,where it is amalgamated. The amalgamation is performed by bringing the free particles of gold in contact with mercury on the copper plate, and the reciprocating motion shakes the crushed ore up, and the water spreads it over the amalgamating-plate, and enables the mercury and gold particles to come in contact. The sulphurets and other heavy particles contained in the ore pulp, sand, and gravel are carried on over the iron plates and gradually separated fromthe lighter particles, and as the separation of the sulphuret-s and other particles has not been completed on the concentrator, the slimes are run onto the slimes- IOO table and over it in a similar manner to complete the separation. The slimes-table is run at the rate of about thirty-five strokes per minute. The concentrating-table is run at the rate of fty-ive to sixty strokes per minute, according to the different kinds of ore. One concentratingtable will run the ore produced by five stamps or batteries, and one slimes-table will run the products of four concentrating-tables,

and one man can attend to iive concentratingtables. It takes but little power to run the tables. A six-inch belt will easily run twelve tables. There is no leakage from them, so

that the attendant can keep his feet dry.

Any person of ordinary intelligence can be taught to run the machines properly in two hoursl time.. The machines are run by steam or water power, as may be most convenient.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination, with the amalgamator and concentrator, as described, and the slimes table, of the double sluice-box having the screen and branch portion, said sluice-boxbeing arranged between the concentrator and theslimestable, and mechanism, substantially as described, for reciprocating the concentrator and slimes-table, as set forth.

2. The combination, with the coneentrator I and amalgamator, and mechanism, substantially as described7 for operating it, of the double sluice-boX having the screen and the shines-table, substantially as specified.

In testimony that I claim the foregoing asl my own I have hereto affixed my signature in presence of two witnesses.

SIMEON TRUBY.
