JIG PUR SEPARATING GRES.

JIG FOR SEPARATING RES.

SPECIFICATION forming part of Letters Patent No. 371,427, dated October 11, 1887 Application filed September 30, 1886. Serial No. 214.908. (No model.)

To tZZl whom it may concern:

Be it known that I, GURDoN GONKLING, a citizen of the United States, residing at Glens Falls, in the county of Varren and State of New York, have invented new and useful Improvements in Jigs for Separating Orcs, of which the following is a speeitica-tion.

The object of my invention is to apply to a central discharge-jig means for controlling the quantity of water used in the operation. Ihe peculiar and novel devices and combinations which I use for this purpose are pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure l represents a vertical central section of a central discharge-jig constructed according to my invention. Fig. 2 is a side View of the dam and gate with discharge-tube in sec tion, the parts being shown on a larger scale than the previous iigurc. Fig. 2* is another side view of the same. Fig. 3 is a horizontal section ofthe same in the plane x x, Fig. 2. Fig. et is a sectional side view of a modification. Fig. 5 is a horizontal section of the same in the plane y y, Fig. 4.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a tub, of wood or other suitable material, in which is placed the jig B. From the bottoni of thisjig extends the tube C, which is open above and below, and which passes through a stufing-box, D, secured to the tub A in any desirable manner. In the tube G is tirmly secured a cross-shaped step-block, c, in which is fastened the shaft Z), that extends to the jig B, which is suspended by means of straps c from a lever, G. The straps c are attached to a sleeved, which tits the shaft b loosely, but is conned thereon by the collars c e', so that said shaft can turn freely in the sleeve; but if the sleeve is raised or depressed the shaft, together with thejig, must follow. The upper end of the shaft Z) extends through a bevel-wl1eel,f, to which it is connected by a feather or key, and said wheel receives a revolving mot-ion by a bevel-wheeLg, mounted on the driving-shaft. The lever G serves to impart to the jig a rising-and-falling or jumping motion in a manner well known.

The bottoni of tliejig is made in the form of asieve, the openings of which are of a size suitable to the material to be separated. The ore to be separated is fed into thejig so as to form an ore-bed about equal in depth to the height ofthe annular ange k, projecting above the sieve, and as the jig receives motion the heavy particles settle down and escape through the meshes of the sieve into the tub, while the light particles, which are the waste, are dis charged with the water through the central discharge-tube, C.

rIhe water is introduced into the tub A through a pipe, I, until it rises to a level of three or more inches above the surface of the ore-bed in the jig. Into the ange k of the sieve is fitted the dam Z, which is suspended by means ot' rods m m from a ring-plate, a. This ri ng-plate turns loosely in a groove formed in a nut, o, which tits a screw-thread on the shaft Z). By turning the nut o, therefore, the dam Z can be adjusted up or down, according to the depth of water over the ore-bed on the sieve. When the jig` is caused to revolve andjump up and down, the waste, together with a quantity of water, is carried over the edge ot' the dam and down through the tube C, and if the mouth of the dam Z is cpen and unobstructed a very large quantity ot' water is required to effect the separation of a comparatively small quantity of ore.

For the purpose of controlling the quantity of water which discharges through the mouth of the dam, I combine with said dam a movable gate, p. In the example shown in Figs. l, 2, 2*, and 8, the movable gate p tits the interior ofthe dam Z, and the dam is made of such a height that its top edge will always be above the level of the water on the ore-bed. In the sides of the dam are openings (one or more) Z', and on the upper edge of the dam are formed two inclines, Z2, and the gate p ispro. vided with two projections, p', which bear upon the inclines Z2, and one or both of which are provided with a set-screw, p2, to hold the gate in any position to which it may be adjusted. The gate, being turned, is raised or lowered, and the openings Z in the dam are uncovered to a greater or less extent. By adjusting the gate in the proper position and securing it in such position by means of the setscrew p, the discharge of the water through lOO the openings Z can be regulated'. The gate p may, however, be left out, and in this case the dam will be adjusted up aud down, so that the openings Z in its sides will be closed more or less by the flange 7c ofthe sieve, and the quantity of water which discharges through these openings can thus be regulated.

In the example shown in Figs. 4 and 5 the movable gate 19 consists of a tube, the diameter of which is equal to. that of the dam Z, and it is held in position by means ot' hooks p3, which slide up and down on the rods m m, and are provided with clamping-nuts p4. By adjusting the gate closer to or farther from the top edge of the darn the quantity of water which is permitted to discharge through the dam can be regulated. l

By combining with the dam Z thev movable gate p, I am enabled to'work thejig with a greater depth of water above the ore-bed than heretofore, and at the same time the quantity of water which discharges can be controlled, so that no more water is wasted than is absolutel y necessary to effect the desi red separation.

What I claim as new, and desire to secure by Letters Patent, is-
