Application filed May 2, 1913. Serial No. 765,171.

To all whom it may concern Be it lmown that I, FRANK PARDEE, a citizen of the United States, and a resident of the city of Hazleton, in the county of Luzerne and State of Pennsylvania, have discovered or invented certain new and useful Improvements in Apparatus for Separating Coal, Ore, 800., of which the follow ing is a specification, reference being had to the accompanying drawings.

The improvements relate to apparatus for separating solid substances of different specific gravity and weight and is of the hydraulic or jig type constituting one means by which the separating operation set forth and claimed in another application filed by me on May 2nd, 1913, Serial No. 765,170, may be practically carried into effect in separating some of the commercial sizes of coal from bone or slate, or in separating various kinds of ores from rock and other foreign substances or impurities.

The invention consists of a combination of elements comprising means for admitting mixed materials to a feed-pipe, means for forcing or drawing water and the mixed materials through said pipe under regulated pressure, a separating chamber into which said feed-pipe leads tangentially, said chamber having an outlet, at its lower end, for the heavier materials, a chamber for receiving the heavier materials when they pass through the outlet therefor in the separating chamber, an exhaust-pipe depending within the separating chamber and means for causing a flow of Water up through said exhaust-pipe for removing the lighter materials from said chamber and means for otherwise circulating and regulating the flow of water, as hereinafter more fully described and claimed.

Figural, of the drawings, is a plan view of the apparatus adapted to the use of water as the fluid or medium for causing the separation of the materials and for cleansing those which are useful and require saving. Fig. 2, is a sectional elevation of the same apparatus.

A centrifugal differential movement is imparted to the mixed materials by the water coming from the feed-pipe which enters a separating chamber, the action in the separating chamber being such as to impart a spiral downward motion of the materials while drawing those of lighter weight inward or toward the central part of the separator. The resistance to the gravitation of the lighter substances is increased so that they slow-up as they come'to a plane or series of planes where they are held for an instant in suspension, and are then drawn into the main vortex and follow the exhaustdraft and are finally delivered separate from the heavier materials.

The materials to be separated are preferably fed through a hopper A, and standpipe 0, to a horizontal feed-pipe 1), opening tangentially into the upper part of a separating chamber B, which is preferably conical and provided with a tight fitting cover B. The stand-pipe a, leads into the feedpipe 6, above, near, or in front of an ejector or nozzle 0.. A cook 0 valve 71, is used to regulate the volume and force or pressure of the water ejected from the pipe I), through the nozzle a. The water is supplied from a tank C, by a pump C, the tail or suction-pipe 0, which by connections not shown, draws its supply from the upper part of the tank C, and the outletor discharge pipe 0, of which connects with a water feed-pipe 0 leading to the valve 6 and ejector or nozzle a. v

The conical separating chamber B, has an opening or spout 6 at its lower end through which the heavier materials drop into a receiving chamber D. The chamber D, surrounds the separator B, to which it is secured by braces d, d, and extends somewhat above the cover B, of the separating chamber B. The feed-pipe 6, passes through the shell of the chamber D, and through the space between the chambers B, and D, so as to open tangentially into the separating chamber as shown in Fig. 2. The chamber D, has a sloping bottom d, which leads the heavier materials to one side where they drop into an extension of the chamber D, forming an elevator compartment as seen in Fig. 1. The formation is such as to deepen the compartment of chamber D, and allow the heavier materials to drop from the sloping bottom 03', to an elevator D, having the scrapers (2 which take up the heavier materials and convey them to a chute (P, in proximity to the dumping end of the elevator, while the water carried by the elevator D, falls back into the elevator compartment. The chamber D, is connected with the fiank C, by a pipe d and controlling valve sired.

which may be opened or closed as de-' A pipe E, passes down into the separating cham j to any desired place or receptacle.

er B, and ends somewhat above the bottom of the chamber or above thes out b, through which the heavier materi pass to the chamber D. The ipe E, passes up through a collar e, and t ough the lid or cover B, and is made adjustable. It is shown as having a threaded upper, end connecting with a flanged threaded coupling a, which joins a dlscharge-pipe e, from which the lighter materials are ejected over a screen e, to a chute e, for conveying tl i elllll e screen e, is placed over a tank F,-..which receives the water from the discharge or outlet-pipe e.

The water in the water-receiving tank F,

returns to the tank 0, through pipe connections f,

2 and is controlled by a valve P, nfir the tank C. The exhaust is caused by a pump G, the tail or suction ipe g, of which connects with tank (Land the discharge pipe g', of which connects with a pipe H leading to an ejector or nozzle h, 1n the discharge pipe 6 so as to produce a jet of water which exhausts from the ipe E, and conveys the lighter materials om the lower part of the separator B. A controlling valve h, is placed behind the ejector k, so as to regulatethe volume and force of the water or fluid coming from the pum G, and that of the suction or exhaust dra for the lighter materials.

Assuming materials of difierent specific gravity and weight to pass through the funnel or hopger A, into the feed-pipe b, and the pump to be set in operation, and mixed substances will be driven or forced through the feed-pipe into the separating eddies and vortices which act to retard the descent of the lighter materials and to draw them inward toward the exhaust pipe E, and also suspend them in the fluid at and near the lower end of the pipe E, so that the lighter substances will be drawn into the main vortex and up through the pi e E, to the discharge pipe e, in front 0 the ejector h, and will be forced over the screen e, to the outlet chute e. The ejected and exhaust water will pass through the screen a, into the water receiving chamber F.

The superior force of gravity inherent in the heavier substances, will cause them to drop below the separating vortex and escape into the receiv ng chamber D. and as from the bottom (1, to the elevator D, w 'ch conveys them to the chute (1% It will be understood that the several tanks, receivers and firliipes throughout the system, are partially led with water when t e pumps are operating. There will always be more or less empty space and some air in the circulation which will aid in the formation of the eddies and convolutions in the separating chamber, but the ap aratus as herein shown and described may e'regarded as essentially hydraulic, serving to wash and to separate the desirable materials or commodities.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In separating apparatus for coal, etc., the combination with a feed pipe, of a separating chamber into which sald pipeleadsj tangentially, said separating chamber having a normally open outlet at its lower end for the heavier materials and an outlet at "a point above the lower en for the lighter materials, a receiving chamber receiving the heavier materials and water from the separating chamber, and adapted to settle said materials from the water, means for separating water from the solids of the efiluent and means connected to both the receiving chamber and the efliuent water so arator for returning the water to the fee pipe and separating chamber.

'2. In separating apparatus for coal, etc., the combination with a hydraulic separating chamber having a normally open bottom outlet, of a receiving chamber inclosing said separatin chamber and communicating with said out et and adapted to settle the solids from the liquid, means for drawing ofi the lighter particles from the separating chamber means for separatin water from the solids of the efiiuent an means connected to both the receiving chamber and the efliuent water separator for returning the water to the separating chamber.
