ACHARLES F. PIKE, OF PHILADELPHIA, PENNSYLVANIA.

OREWASHER OR CONCENTRATOR.

` SPECIFICATION forming part of Letters Patent No. 528,974, dated November 13, 1894.

Application filed June 10, 1893. Renewed April 1'7l 1894. Serial No. 507,939. (No model.)

o all whomit may concern.-

Beit known that I, CHARLES F. PIKE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphiaand State of Pennsylvania, have invented certain new and usefulImprovements in Ore Washers or Concentrators; and I do hereby declare the following to be a full, clear, and exact decription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to ore washers or concentrators of the form having a feed and a suction or forcible discharge; and it has for its object to adapt the same to a flume supply for handling economically, thoroughly, and efficiently large bulksof ore or gangue.

My invention accordingly consists of the combinations, constructions and arrangements of parts as more fully described in the specification and pointed out in the claims.

Reference is had to the accompanying drawings, wherein- Figure lis an'elevation partly sectional of a form of washer and a Hume supply embodying my improvements. Fig. 2 is an end view of rotating screen and its support interposed between the fiume and washer. Fig. 3 is a view similar to Fig. 1, illustrating another form of screen between the flu me and washer. Figs. 4, 5, 6, and 7 are sectional elevations of still other different forms of screens or separators interposed between the ume or supply and the washer. Figs. Sand 9 are respectively, a plan and side elevation of a perforated Ahinged bottom for the receiving vessel of a washer of the forms shown in Figs. 1 and 2. Figs. 10 and 1l are sectional elevations partly sectional of additional forms of screens or separators between the supply and the washer, and Fig. 12 is an elevation showing a modification of separator indicated in Fig. 10.

A in Figs. 1 and 3 represents a form of orewasher or concentrator having supply tubes aafor feeding into the washer different grades of ore or gangue, a suction or other discharge appliance a', a suitably constructed chamber t. n ber a8, and rotating screen B, see more plainly Fig. `2, having different meshes b b constructedand arranged foroperation substantially as shown, described and claimed in a pending application filed by me of an even date herewith, Serial No. 477,164.

C represents an ore supply chute or flume which may be suitably located relatively to` the feed device c. of the Washer or concentra` tor A as desired or the demands of service require. In Fig. lits discharge end is shown entering the screen B for the feed devices a a. In Fig. 3 such flume is indicated discharging into a receptacle c to be hereinafter described while large Waste-matters pass off of its terminal end. Said ['lumeis at any suitable location along its length provided with a perforated or other grating or screen c below which is a chamber c having a pipe connection d with a valve d', with washer A or its chamber as to provide an inflow of water to the washerit having if desireda suitable overflow pipe f.

The object vof providing the screen c and chamber c with supply pipe d for the washer is to admit of utilizing a partof the flow-water on the fiume as a supply for the upward or otherwise directed current in chambers c3 and a2 of the washer for agitating the ore or gangue fed to chamber a2 from tubes a a.

In Fig. 3, the rotating screen Bis dispensed with, the large useless bulky material passing off of the end of the flume at c2 and conveyed away from the machine by a chute c3. The chamber c is provided with a deflecting partition e and a grating or perforated plate e1 for preventing any gangue or ore pasisng to the chamber a3 of washer A. The outlet pipe dmay lead out from the bottom of chamber c as shown in full lines in Fig. 3 or from near the top of same as indicated by dotted lines. In the latter case the opening of the outlet pipe d is protected by a detlecting plate e3.

In Figs. 6, 7, 8, and 9 the flume or supply chute C is shown terminating in aboX or large receptacle c above the fiume and without screen but having a gate or valve c4, and said figures show various ways of locating and arranging pipe d.

Fig. 12 shows a funnel shaped screen or separator having pipe d attachment, and the box c has a screen and bulky material outlet with yIOO valve c4 for regulating the discharge of gan gue or ore to the feed tubes for the Washer.

From the foregoing it will be noted that the ore or gangue in the Water on the flume or chute C is conducted to the feed devices a of the Washer and that part of the Water on the fiume which is most devoid of sand is conducted by aseparate pipe d to the chamber a3 of said washer for supplying the inward and upward current from the outer chamber a, to the inner receiving chamber a2 of the washer for eecting agitation of the ore or gangue supplied to chamber a2; that in some of the forms of construction the water from the iiulne for pipe d has more or less of the light material of the ore or gangue mixed with it. I prefer however the use of the first above described arrangements or that in which the feed water from the flume for pipe d is devoid as near as maybe of any solid matters of the ore or gangue.

AsV it is obvious that the construction and arrangement of the novel features and operations herein described by me may be changed without departing from the spirit of the in- Vention, I do not confine myself to the same as shown and described.

l. In combination with an ore washer or concentrator havinga feed device and a suction discharge device, of a fiume or chute leading to said feed device,` and a pipe connection between the washer and the ilumeor chute for conducting part of the water on the flume to the Washer for agitating the ore or 3 5 gangue supplied to the washer by its feed device, substantially as set fort-h,

2. In combination with an ore washer or concentrator having a feed device and a suc tion discharge, of a flume or chute having a valve at its discharge end for controlling the flow of ore or gangue and water from the chute to the feed device for the washer, of a pipe with valve between the Washer and the Water level on the flume for providing a separate water supply from the ume to the Washer for agitating the ore or gangue supplied to it by its feed device, substantially as set forth.

3. In combination with an ore Washer or concentrator having a feed device, a fiume or chute C leading to said feed device, a coutrolling gate or valve at the exit end of said fiume, and a conduit leading from the water level on the fiume to the Washer or concentrator, substantially as set forth.

4t. In combination with an ore washer or concentrator, a tiume or chute C having an exit end controlling gate, and connection from above the bottom of said fiume to the Washer or concentrator, substantially as set forth.

In testimony whereof I affix my signaturein presence of two witnesses.

CHARLES F. PIKE.
