CLAUDE N. BIELENBERG AND ALBERT E. ROBISON, 0F DEEE LODGE, MONTANA.

ORE CONCENTRATOR.

Application filed November 26, 1923.

To @ZZ whom t may concern:

Be it known that we, CLAUDE N. BinLnN- enne and ALBERT E. RoersoN, citizens of the United States, residing at Deer Lodge, in the county of Powell and State of Montana, have invented certain new and useful improvements in Ore Concentrators, of which the following is a specification.

This invention relates to ore concentrators of that type wherein the separation of the values or heavier metal particles and the gangue or lighter constituents from the ore is effected by the combined action of a washing` operation and an agitating operation.

The primary object of the invention is to `generally simplify and improve ore concentrators of the above kind whereby the same will be rendered extremely effective in operation and will be simple and durable in construction. f

Another object ofthe invention is to provide an ore concentrator embodying an elongated shaking box or table in the general form of a trough provided with baffling plates, and means for adjusting the distance between said plates and the bottom of the box or table whereby the box may be ef` fectively operated in connection with ore of varying coarseness.

Still another object of the invention is to provide the adjustable slides with horizontal baffling boards whereby maintenance of the heavier metal particles at the bottom of the box or table will be insured, provision being made by a peculiar construction of the sides of the box for facilitating the flow of the gangue over the sides of the box to a desired point of disposal.

Still another object of the invention is to provide a novel and improved arrangement of washing means whereby the ore will be subjected to jets of water in the shaking table or box for effectively breaking up and dissolving the ore constituents, so that the values will readily separate therefrom.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination, and arrangement of parts hereinafter more fullydescribed, shown in the accompanying drawing and claimed.

In the drawings wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a top plan view of an ore Serial No. 677,087.

concentrator constructed in accordance with the present invention.

Figure 2 is a longitudinal sectional view thereof, taken substantially upon the line 2 2 of Figure l.

'Figure 3 is an enlarged transverse sectional view, taken upon the line 3 3 of Figure l, and

Figure 4 is an elevational view of one of the baffling slides and its attached horizontal baiiiingplate or board.

Referring more in detail to the drawings, the present invention consists of an elongated open top box including side walls 5 having longitudinal grooves in the inner faces thereof adjacent their lower edges7 in which the opposite longitudinal edges of a bottom wall 6 snugly fit, and the walls 7 and 8 being provided between the side walls 5 with their side edges disposed in vertical grooves in the adjacent faces of the walls 5 as shown clearly in Figure l, the end walls 7 and 8 being provided with grooves in the inner faces thereof, near their lower ends in which the ends of the bottom walls k6 are seated, and tie bolts 9 being provided between the projecting ends of the side walls 5 outwardly of the end walls 7 and 8 for securing the several walls of the box construction rigidlyl assembled.

The box thus constructed is gradually reduced in depth from its intake end at the end walls 7 to its discharge end at the end wall 8, by providing inclined upper edges on the side walls 5 and forming the end wall 8 of shorter size than the end wall 7. The box also tapers narrower in width toward its outlet end by providing converging side edges on the bottom wall 6 as shown clearly in Figure l, and the interior of this box is divided into a plurality of successively smaller compartments by means of a plurality of vertical substantially uniformly spaced slides 10 whereby compartments are provided which vary in size according to the sizes of the values concentrated or collected inthe bottoms of said compartments.

The side walls 5 are provided with aligned u and the lower edges of each of said slides.

In thev construct-ion shown, each slide 10 is provided With an internally threaded boss 12, at each side of the same and at the upper end thereof, through which the screws 11 are threaded, and whereby the said screws are positioned to bear upon the upper edges of the side Walls for effecting the above mentioned adjustment. n

Suitably rigidly secured to the lower end of the slide are horizontal battling boards 12 that project toward the outlet end of the bex and which act to keep the metallic particles in the box. In order to facilitate flow of the gangue over the sides of the box, behind each of the'slides 10, the upper edges of the` side walls 5 are notched or cut away at diametrically opposed points as indicated at 13.v Y

The ore washing device of the construetion consists of a pair of longitudinal nozzle pipes 14 that are seated within grooves provided in the upper surfaces of the bottom walls 6 and thek side edges thereof and in the inner faces of the side walls 5, said pipes or notches being provided with a longitudinal series of openings at 15 upon their inner sides and substantially flush with the upper surface of the bottom wall 6, so that when water is supplied under pressure Yto the pipes 111-, the saine will flow inwardly 1n opposite directions and transverselyv of the box in relatively strong jets, whereby the ore will be effectively dissolved and washed.

l.with respect to certain constituents thereof,

it being noted that the flow longitudinally of the box is induced, due to the gradually reduced depth of the same. The ends of the nozzles or pipes 14 may be connected to a common manifold pipe 16 at the intake or higher end of the box, which manifold is connected with a suitable supply pipe 1T having a control valve 18. The depth of the pipes 14 at the shallower or outlet end of the boxY are closed by suitable means such as caps as indicated at 19, .and the table or box4 is adapted to be laterally Yreciprocated or given a jigging movement through the medium of suitable mechanisms well known in the art. Such means is diagrammatically shown as consisting of a power shaft 20 having end cranks 21 connected with one of the side walls v5 through the medium of links 22. j In operation, the ore is depositedwithin the larger end compartment of the box at the deeper end of the latter and the valve 18 Vis vopened for permitting the water to flow through the openings 15 in a plurality of strong `jets transversely of and across the upper surface of the bottom wall (t, it being understoinl that the gates or slide valrcs 10 have been previously ai'ljusted to the require/e height in accordance with the, material to be handled. The actimi of the water impinging against the ore tends to dissolve the ganglio so that the same may rise to the top of the water and flow over the top edges of the side *alls particularly at the notches 19, The coarser metal will be retained within the largeiI end comjnirtment and the successive comjmrtments will retain the values in :arcordance with lhe sizes thereof and the dill'erent :n'ljusi'ments` of the several slides 1t). Also, the 'halling boards 12 while permitting the lighter eonstituents to rise and overllow at the notches 19 will effectively tend to keep the heavier particles or metals within the box below said notches lf). The concentrated metals may be recovered from the several compartments in any preferred or well hnown manner.

An ore concentrator constructml in aecordance with the above will he found to operate with extreme ellieieney and may he constructei'l and operated at a comparatively small cost, and provides a structure which will be extremely durable.

llVhat I claim as new is:

1. In an oro concentrator, an elongated box having means for reciprocating the same laterally, said box including side, end and bottom walls, and opposed longitudinal water pipes disposed at the juncture of the. inner surfaces of the bottom Vall and side walls and having longitudinal series of jet openings in the inner sides thereof through which water may pass in jets travelling in `wardly toward `each other across the upper surfaceof said bottom wall.

2. ln an ore concentrator, an elongated box including end, side and bottom walls, the upper edges of said side walls inclining from one end toward the other whereby the depth of the box is gradually increased from the intake to the outlet ends thereof, vertically adjustable slides arranged in spaced parallel relation between the side walls and extending transversely of the hox, said side walls having notches in the upper edges thereof at the rear sides ot each of said slides, and horizontal battling boards rigid with the lower ends of the slides and extending from the latter toward the outlet ends of the box.

In testimony whereof we allix our signatures.
