7 Application filed March 16, 1898- To all whom it ma concern: p

I Belt known that I, CARROLL B. ROGERS, of

El Paso, in the county of El Paso and State of Texas, have invented a new and Improved Slime-Jigging Machine, of which the following is a full, clear, and exact description.

This invention relates to improvements in slime-jigging machines; and the object is to 2, showinga slime-jigging machine embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is a plan View showing the construction of a screen-frame employed. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. 6 is an elevation of a gate and latch employed, and Fig. 7 is asection through the line '7 7 of Fig. 6. V

Referring to the drawings, 1 designates a tank of any suitable size and construction and having vertical side walls. This tank is provided with a bottom portion, which consists of a suitable horizontal section, '(clearly indicated in the drawings,) of an intact substantially V-sh aped base 2, having a'continu ous and uniform downward inclination from said horizontal section to the bottom of the opposite vertical side wall of the tank, and of, suitably-shaped upwardly-flaring side walls, the latter forming with said base a chute-like structure the internal dimensions of which continuously decrease from the upper to the lower extremity thereof. The tank 1 is further provided with an outlet 3, normally closed by a gate 4, held from movement by internal pressure by means of a latch 5. The latch 5 consists of a bar secured to the tank or to its frame and having an outwardly and downwardly turned portion to engage against the outer side of the gate-handle. This will allow an upward movement of the gate, but

gitudinal strips 16 and cross-strips 17. frame rests on ledges l8,secured to the inner ,wall of the tank 1 and to the partition 6. For

will preventits being forced outward. Extending across the'tank 1, about midway of its front and rear walls,'is a partition 6, the bottom of which terminates at a point somewhat short of'the base 20f the tank-bottom portion and somewhat below the plane of the horizontal section of said bottom portion. Operating in a chamber at one side of the partition 6 is a plunger 7, which has a rod conplunger.

In the compartment opposite thatoccupied by the plunger 7.is a screen 15. This screen is designed to be stationary, and therefore it is mounted on a metal frame consisting of lon- This convenience in fastening the screenmaterial in position I provide the several strips forming the screen-frame with longitudinal channels 19,-in which wooden strips are seated. The screen material 15 is secured to the strips 20 by means of nails 21, which are preferably of copper, as copper nails are not liable to corrode. 7

Above the screen 15 the tank 1 hasa valvecontrolled communication 22 with a concencrate-receiver 23. The valve for controlling the outlet 22 consists of a plate 24, movable in guides 25 This concentrate-receiver 23 has a pipe 26 for discharging the heavier particles of concentrates into a lower concentratereceptacle 27, which, as here shown, is designed to be placed under the tank 1 and is removable therefrom. The pipe 2613 provided with a suitable valve 26 At the front of the tank 1 is a hopper 28 for the material tobe treated. The material inserted through this hopper 28 will fall onto the screen 15, and at the opposite side is a bridge-wall 29, over which the tailings or other refuse may fall into a tailings-receptacle 3 0. This ta'ilings-receptacle is arranged exteriorly to the tank 1 at the bridge-wall 29 and is capable of maintaining the level of the water therein and within the tank proper normally above said bridge-wall. It is also provided with a valve-controlled outlet 31, and the valve for this outlet is designed to be so regulated as to only take off the gangue, causing the water and light slime to be backed up, doing away with a current of water as ordinarily used and which carries oif fine particles of minerals. At the upper portion of the tank 1 and at the rear end thereof is an overflow-plate 32 for the discharge of any excess of water in the tank. The tank bottom portion hereinbefore described and the arrangement of the partition 6 with respect to said bottom portion constitute essential features of my invention, the same serving in practice to so control or modify the currents or pulsations created in the wash-water within the tank 1 through the reciprocating movements of the plunger-7 as to insure a highlyeffective application of said washwater to the ore-bed on the screen 15 in the screen-compartment of the tank, and in this connectio'n the horizontal section of said bottom portion serves at each downward thrust of the plunger 7 to bafile the Wash-water within the plunger-compartment of the tank and abruptly divert the same laterally to and against the partition 6, which in turn baflies said water, and by reason of the lower extremity thereof terminating at a point somewhat below the horizontal plane of said horizontal bottom section abruptly diverts said water downward upon a portion of the inclined surfaces presented by said bottom portion, from which latter point said water makes its Way chiefly to the opposite vertical side wall of the tank 1, and thence to the screen 15 by way of the screen-compartment of the tank. These abrupt bends in the course of the washwater from the plunger-compartment of the tank to the screen in the screen-compartment of the tank, brought about, as they are, by the peculiarly-formed parts which I employ, serve to insure a highly-effective application of the wash-water to the ore-bed on the screen 15.

In operation the slime or ore to be treated will be placed upon the sieve substantially to the level w. Then the tank is to be tilled with water through the supply-pipe 33, after which the plunger'7 is to be put in operation. vertical movements of the plunger 7 will agitate the water in such manner as to give a pulsating motion to raise the ore-bed on the sieve and allow the bed of ore to flow by its own gravity, the heavy particles of mineral, &c., sinking to the bottom and the light gangue being forced on top. The chlorid and fine valuables which remain in suspension in the water may be caught by skimming the light top overflow, which may be regulated as desired. A portion of the valuable mineral will fall into the water below the sieve, and lighter portionsthat is, portions too light to remain in suspension or to rise to the top of the water-will pass through the The opening 22 into the receiver 23. The floated tailings will pass over the bridge 29 into the tailings-receptacle 30, from which they may be removed, as before described, and the concentrates falling into the chamber or space below the sieve and to the bottom thereof may be removed as desired through the outlet 3.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1.
