SPECIFICATION formingpart of Letters Patent N0. 593,837, dated November 16, 189?. Application filed August 31, 1897. Serial No 650,112. .(No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. DUNTON, a citizenof the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Circulatin g Liquids in Tanks and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improved apparatus for continually circulating and thoroughly agitating all kinds of liquids, more especially for use in continually circulating and thoroughly agitating depositing solutions in all kinds of electrolytic baths in a definite direction.

It has for its object to provide an apparatus which will keep the heavier and acid portions of the liquid continually moving, thereby insuring its thorough incorporation throughout the whole body of the liquid, not allowing it to lie at the bottom of the tank, as would be the case if such circulation and agitation were not. continually going on, but at the same time not disturbing the sediment at the bottom of the tank; and it further has for its object to make thedeposits of the metal at the cathodes finer in grain and tougher in texture and to render the time of the deposits shorter and'keep the solution from becoming heated in the process of working. Heretofore many plans have been tried to accomplish these objects, but none have been in the least successful, as all had serious faults which in practical use rendered them utterly worthless.

My invention consists of a containing-tank for the liquid composin g the electrolytic bath, having means located therein for imparting a definite and continuous circulating or approximately circular motion of' the solution to force it around and between the anodes and cathodes, said means comprising a pump,preferably a centrifugal pump of the turbine pattern, but may be of any other pattern which is capable of doing the work required, said .pump having an inlet or inlet-strainer near side at a point below the level of the liquid contained in the tank. I 1

My invention further consists in the conof the parts comprising said apparatus, as more fully hereinafter described inthe specification and set forth in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a plan view; Fig. 2, a side elevation, partly broken away; Fig. 3, a sectional View taken on the line 1 1, Fig. 1; and Figs. 4 and 5, sectional detail views of the pump. r I

In the drawings, in which like letters ofreference denote like parts throughout the several views, A designates an electrolytic or containing tank; B, a centrifugal pump of the turbine pattern located in one corner of said tank; 0, the casing of the turbinewheel, said casing having a pipe 0 leading therefrom to the top of the tank on the opposite side and provided with adischarge 0 D, the vertical suction-pipe, having a'strainer or inlet E at its lower end; G, the turbine wheel located in the casing C; H, a vertical shaft on which the wheel G is journaled, said shaft G, a bearing J in the top of. the suction-pipe D, and a bearing K at the top of the tank.

L is a miter-gear on the upper end'of shaft miter-gear on the inner end of a horizontal skaft N, supported in a bracket 0 at the top of the tank and meshing with gear L; P, a pulley-wheel on the outer end of the shaft N, to which power is transmitted by belt or any ning across the tank for supporting anodes R and cathodes S; T, links for suspending the anodes from the bars Q.

The operation is as follows: The electrolytic bath having been properly prepared and the pump started, the heavy solution is drawn in through the strainer or inlet E from the bottom of the tank at one corner and discharged through an outlet 0 in a pipe 0 at the top of the tank on the opposite side, this operation being continuous and causing the solution to take a circular motion around and between the anodes and cathodes.

What I claim is- 1. An apparatus for producing continual struction and combination and arrangement.

being supported in a hearing I in the casing other suitable means; Q, rods or bars run- H; H, a spring located under gear L; M, a

and definite agitation and circulation of liquids, comprising atank, anodes and cathodes therein arranged side by side, and having a space between their ends and the tank, a pump having an inlet, and an outlet-pipe provided with a substantiallyhorizontal nozzle near the top of the tank, arranged substantially at a right angle to the plane of the anodes and cathodes, and in the space between their ends and the tank, whereby a circulation of the liquids in and entirely around the tank is elfeeted, substantially as described.

2. An apparatus for producing continual and definite agitation and circulation of liquids, comprising a tank, anodes and cathodes therein arranged side by side, and having a space between their ends and the tank, a pump having an inlet or suction opening, and an outlet-pipe provided with a substantially horizontal nozzle near the top of said tank, said outlet-pipe leading across the bottom of the tank, then up to a point near the top of the same on the opposite side thereof to that occupied by the pump, and arranged substantially at a right angle to the plane of the anodes and cathodes, and in the space between their ends and the tank, whereby a circulation of the liquids in and entirely around the tank is effected, substantially as described.

3. An apparatus for producing continual and definite agitation and circulation of the liquids composing a bath, comprisinga tank, anodes and cathodes therein arranged side by side, and having a space between their ends and the tank, a pump located in one corner of said tank having an inlet near the lower end of the suction-pipe, and an outlet-pipe provided with a substantiallyhorizontal nozzle near the top of said tank, said outlet-pipe leading from the casing at the lower end of the suction-pipe to a point near the top of the tank on the opposite side thereof to that occupied by the pump, and arranged substantially at a right angle to the plane of the anodes and cathodes and in the space between their ends and the tank, whereby a circulation of the liquids in and entirely around the tank is effected, substantially as described.

t. An apparatus for producing continual and definite agitation and circulation of the liquids composing an electrolytic bath, comprising a centrifugal pump havinga suctionpipe provided with an inlet-strainer near its lower end, a casing at the lower end of said suction-pipe having an outlet-pipe leading therefrom to a point near the top of the tank and on the opposite side, a turbine wheel located in the casing, a shaft upon which the turbine wheel is j ournaled supported in bearin gs in the upper and lower part of the pump and at the top of the tank, a gear-wheel on the upper end of said shaft, a gear-wheel on the inner end of a horizontal shaft supported in a bracket on the top of the tank and n1eshin g with the gear on the shaft; and a pulleywheel on the outer end of the horizontal shaft adapted to receive power from any suitable source, substantially as described.

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

GEORGE E. DUN ON.
