ORE-CONCENTRAT'O R.

SPECIFICATION forming part of Letters Patent No. 319,857, dated June 9, 1885.

Application filed March 11, 1885. (No model.)

To all whom it may concern:

Be it known that I, ELLIs W. SINCLAIR, a citizen of the United States, residing at Tombstone, in the county of Cochise and Territory of Arizona,have invented certain new and use ful Improvements in Ore-Concentrators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to machines for sorting or concentrating ores and it consists in the construction and combinations of parts,as

hereinafter more fully described, and specifically pointed out in the claims.

In the annexed drawings,illustrating the invention, Figure 1 is a plan or top view of my improved ore-concentrator. Fig. 2 is a side elevation of the same. Fig. 3 is an end elevation of the machine. Fig. 4 is a cross-section of the vibratory concentrator-box. Fig. 5 isaplan of the agitator-fingers. Fig. 6 is an end view of the bar or gate for closing or adjusting one of thelongitudinal discharge-openings, and showing one of the locks for same. Fig. 7 is a side elevation of the concentratorbox, with a portion of the frame of the machine partly in section. Fig. 8 is a side View of the plate for supporting the agitator-fingers, showing its operative connection with the cocentric-shaft. Fig. 9 is a cross-sectional perspective on the line w of Fig. 1.

Like letters of reference designate like parts I in the several views.

A is the frame of the machine, and A A are the top side bars, one of which, as A, is placed somewhat lower than the other, so as to afford a support for the spring is, that holds the concentrator-box B to the action of the cams K K, by which said box receives a lateral jar or vibration, as hereinafter explained. The vibratory concentrator-box B is adjustably suspended from the frame of the machine at any required height by means of hooked rodsPP-two at each end-having adj usting-nuts g g at their upper ends. The conl centrator-box B is long and narrow, and is provided near the bottom on each side with a longitudinal opening, as cand 1), extending nearly or quite the entire length of the box. The floor or bottom of the box B is formed in side d being somewhathigher than the other, and provided at its upper edge with a longitudinal rib or flange, 'e, that prevents any of the fine ore from being pushed or carried off by the coarse particles over and through the wastedischarge 1).

Attached to a bar, B,within the box B, on one side, is a longitudinal divisionplate, S, that is suspended vertically above the trough or depression produced by the junction of the inclined bottom pieces,c d, a narrow space or opening being left beneath said plate or par- B is effected from a shaft, 0, that is jonrnaled tries D D D,a flywheel, E, and a driving two outer eccentrics, D D, are set in the same direction, and are connected by hooked eccentric-rods h h to castings U U on the box B, as shown in Figs. 1, 2, and 7 ,an endwise vibration being thus imparted to the concentrator-box by the rotation of the eccentric-shaft, said box being suspended by the hooked rods P P, as before described. The middle eccentric, D,is set in an opposite direction to the eccentrics D D, and is connected by a hooked eccentricrod, h, to a casting, T, on a vertical plate, Q, that carries at its lowerend a series of laterallyprojecting inclined fingers or agitators, R R.

metal, and extend the entire width of the inclines c d, and nearly in contact therewith, as shown in Fig. 4, spaces being afforded between the fingers, as shown in Fig. 5, for the passage of fine material below the level of the dischargeopenings, so that none can float off on the water with which the concentrator is supplied.

The level of the discharge on each side of the concentrator is shown by dotted lines in Fig. 4. This level rises and falls on oneside with the gate 0, when the latter is adjusted up or down, as hereinafter explained.

It will be observed that the hooked rods P P, for suspending the concentrator-box, are supported in lugs or projections p 1), attached to or formed on the ends of the machine-tram e. The upper edge of the plate Q is flanged at Q, as shown in Figs. 1, 4,8, and 9, said flange Q being extended at each end of the plate and provided with bearings Q that are supported upon each end of the box B in guideways b b, of snfficient width to permit the necessary vibration of the parts.

On one end of the shaft 0 is a bevel-pinion, G, that meshes with a bevel-gear, H, on the end of a shaft, I, that is journaled at the side of the machine and carries the cams K K, which impart at intervals a percussion that causes, in connection with the spring k, a lateral vibration of the concentrator-box B, as before referred to. The cams K K strike against projections s s on the concentratorbox, and so vibrate it laterally against the pressure of the spring k on the opposite side, said spring being adjusted to any required ten sion by bolts m m, as shown in Fig. 1. After the cams K K have rotated sufliciently, the box B vibrates to a vertical position, with its projections s 8 bearing against projections pp on the main frame, and "position to be further acted on by th V Muslin their continued It will thus be seen that while the box Bis vibrated in an endwise direction in opposition to the back and forth movements of the agitator-fingers B B, it also receives a literal jar or vibration from the movements of the cams K K.

The ore-discharge opening a may be closed or opened to any required extent by means of an adjustable gate, 0.

To the gate 0 are attached eccentric-straps M M, that pass around eccentrics L L on a rod, L, that is supported or journaled in notches f, formed in the concentrator-box, as shown in Figs. 3 and 4. The gate is raised or lowered by rotating the rod L, and may be secured at any desired height by means of a hand-wheel, N, on a threaded bolt, N, Fig. 6, which enages perforations in the eccentric-straps M, and so looks or secures the gate in the position to which it may have been adjusted. The rod L may be rotated by means of pins or handles m, attach ed thereto, after the hand-wheels N have been turned to relax the eccentricstraps M, the rod being afterward secured in the position to which it is rotated by again tightening said straps.

The gate 0 is held in place against the side of theboxB by means of spring-clamps t t, Fig. 2, the upper ends of which bear against projections n n on the main frame. (Shown by dotted lines in Fig. ,4.) If desired, the outer surface of the box B may be grooved back of the gate 0, for the reception of a packingstrip, 1;, as shown in Fig. 3, and so form a close joint for the gate to prevent leakage when said gate is closed.

To the gate 0 is attached a trough or spout,

.B, that extend beneath the division-plate S.

The inclined upper surface of the bar B breaks the force of the fall, and thus prevents a remixing of any particles of ore that have already settled. The box B and fingers R R are vibrated at the rate of from two hundred and twenty-five to three hundred shakes a minute, different kinds of ore requiring different degrees of speed; but the ore must be kept in a perfect tremble, which is the best possible condition for the heavy particles, however fine, to settle to the bottom. This is greatly aided by the lateral jar to which the concentrator is subjected. As the current of water is completely broken by the jar and tremble of the machine,it does not have any tendency to carry off the fine ore, especially as less water is re quired than in ordinary machinesof this class. The ore that settles between and beneath the fingers R B passes off through the opening a into the trough or spout V, the level of the discharge, as shown by dotted line in Fig. 4, being varied as required, either by adjusting the gate 0 throughjthe eccentric-straps M M and rod L, or by raising or lowering the box B through the rods 1? P and adjustingnuts g g, as before mentioned. The waste passes off through the opening b into the trough or spout W, the fine ore being prevented from escaping at that side by the rib or flange e on the outer edge of theincline d. The inclines c and d, being preferably covered with amalgamated copper, serve to retain any fine particles of gold or silver that may have escaped in the tailings from the battery stamps or pans. The machine is compact, and thus requires but little space. It'will work equally well on all ordinary sizes of ore, mixed, from a sixteenmesh screen down to fine dust, and therefore a sizing-machine, as ordinarily used,'wi11 not be required.

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

1. In an ore-concentrator, the combination, with the endwise and laterally vibratory box B, having a double-inclined bottom, 0 d, and discharge-openings a b, of plate Q, provided with the thin inclined agitator-fingers R R, having an endwise movement contrary to that of the concentrator-box, substantially as described.

2. The concentrator-box B, having openings a b and a bottom composed of two inclines, c (1, one of which is wider and higher than the other, and is provided with a longitudinal rib 15"'N N and hand-wheels N N, substantially as described.

5. The combination, with the concentratorboX B and adjustable gate 0, of the trough or spout V, attached to and movable with said gate, substantially as described.

6. An ore concentrator comprising the framelA, vibratory concentrator-box B, having discharge-openings a b, double-inclined bottom 0 d, division-plate S, and adjustable gate 0, the movable plate Q, carrying fingers R R, the shaft 0, having pinion G and eccentrics D D D, the rods h h h, the castings on the box B, the shaft 1, carrying a gear, H, and cams K K, and the adjustable spring k, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ELLIS W. SINCLAIR.
