Letters Patent. Patented Feb. 26, i907.

Application filed November 27,1905. Renewed January 22, 1907. Serial No. 353,525

.To (tl/f whom it 'may concern.;

Be it known that I, JOHN M. CALLow, a subject ol the King of Great Britain, residing at Salt Lake City, in the county ot Salt Lake and State of Utah, have invented new and useful Improvements in Settling-Tanks, ot which the following is a specification.

ln settling-tanks used in treating the slinies ol ores it is of great importance that the ineans employed for drawing oil the values should not only ell'eet that withdrawal coinl pletely, but should do it without agitating the mass in the tank. lt should also include nieans for flushing and cleansing the vents and ducts connected therewith. These functions require an accurate .adjustment of the inlets and outliows and careful calculations as to the pressures andcther intermediate and iinal eltccts involved.

rlhis device is siphonic and comprises, essentially, a direct downward channel whose vertical axis alines with that of the settling! tank. In this channel is located a threeway valve. which' will permit a direct ilow through it or will cut oI'l' the llow and letin a current 'from a lateral pressure-pipe, which may be directed upward or dmvnward, as desired. v

@ther features of' this device will be explained in the description jfollowing.

The drawings herewith illustrate theinvention, its` various 'features being referred In the drawings, Figure l'is a vertical section ot the device attached to'the lower part of tunneldorin settling-tank, the latter being shown liragnientarily. Fig. 2 is a vertical section taken at a right angle to that of F ig. 1. Fig. 3 is a side elevation, partly in section, showing a niodiiication ot the device.

The letter A (,lesignates a funnel-.torni settling-tan k having an outlet a at its lower end.

lBv is a casting attached to the lower end of the tank A and serving as an exit therefor. This casting has a vertical channel b opening into the tank, its axis being in line with the axis of the tank, and a lateral channel g2 continno'us with said channel b and extending on into a pipe H.

C is a valve-chamber formed by enlarging i the channel either in the casting B or the pipe ll. This valve-chamber has a lateral opening c, provided with a cap e.

l) indicates -a thrceway valve located in the chamber C and having ocnings (Z, d?, and d3. d is a stein on said va ve connecting with a lever c, by means of which the valve may be turned to control the flow Afronrthe tank or from a pressure-pipe I, having a channel i, which connects with the lnain channel through a core et in the chamber C.

f is a stopper for the opening b of the channel b.

G is a lateral extension of the casting hav ing'the channel g2.

J is a flexible hose connecting with the pipe H and provided with the nozzle j.

In the operative adjustment of the device shown in Big. 1 the iiow of the settled Inaterial is down through the valve D and by way of the lateral channel g2 and pipe H out through the hose and nozzle; but if by the accidental introduction of foreign matter into the tank an obstruction gradually accumulates within the casting B or the pipe H or hose J and the free discharge of settlings Y ceases, by operating the valve D water'under a high pressure can be intro duced for the purpose of removing and ejccting such obstructions. Should any obstruction occur beyond the valve D, by a partial revolution of the valve the connection to thetank is cut oil', and high-pressure water through t forces its way through the channels b and g and out through the nozzle. Should the obstruction occur in the throat of the casting, a simple reversal of the valve-lever shuts olifthe conl' ncction beyond the valve, and the full pressureV of water is brought to bear ori-the 0bstruction-here and to brealit rip. Then by bringing back the valve to its'iirst position and removing the stopperthe pressure ofthe v water in the tank above and gravity will together expel it through the passage b.

What l claim, and desire to secure, is-

1. In a settling device, a tank provided` with a discharge-opening, an exit-casting attached to the lower end of the tank and having a vertical channel connecting with the opening in said tank, a connectlngpipe, said pipe and the casting having a lateral outletpassage connecting with the vertical channel wthrough said casting, said discharge elements being provided with a valve-chamber, a three-Way valve. therein, means to operate the same, and a pressure-pipe conneetin' through said valve with the channel and wit thclateral outlet as described."r

2. In a settling-tank an exit-casting attached to the lower end ot said tank, andvliaving a vertical channel connecting `.vitlif the opening in said tank, a stopper for'the lower end of Said channel, said casting having u valve-Chamber, a three-way y'nhe in said ehainbermeans to operate said valve, pressure pipe connecting with said channel lhrough said valve said casting having a interal outlet from said channel beiow .sa-id valve as described.

3. The combination with n funnei-for1n settling-tank having an opening at its lower ps1-rt, of @casting having :i vertical channel conneqfuing with said openingand provided with a cvalve-chamber, a. three-wry Valve in said 'chamber, a pressure-pipe. connecting 'through said valve with said ehzmnoi, 'a stopi 5 per at the lower end of sind channel, a lateral out1et-pipe between said valve and the lower end of said channel, an upwardly-inclined y pipe connecting with said Aoutlet-pipe, and .a flexible hose on said inclined pipe for the purposes specified.

4. In zi`settling-tank, a bottom casting having e. veriezi-l and f1. lateral channel, a.

stopperfor Said Vertical channel, a pipe Conheating with sznd lateral channel, :L threeway valve in sii-id pipe and a pressure-pipe Connection with sind valve, for the purpose specified.

in testimony whereof l affix my signature in presence oi' two subscribing Witnesses.
