APPARATUS FOR PURFYING, STERlLIZING, AND AGING LlQUlDS.

Specification of Reissued Letters Patent.

Reissued Dec. 12, 1905.

Original No. v725,803, dated April 21, 1903. Application for reissue iiled July Z8, 1905.. Serial No. 271,707.

of Ohio, have invented certain new and use-I ful Improvements in Apparatus for Purifying, Sterilizing, or Aging Liquids; of which the following is a specification.

This invention relates to apparatus for purifying, sterilizing, or aging liquids; and it consists in improvements upon the apparatus shown in my Letters Patent of the United States No. 524,121, dated August 7, 1894.

With my present apparatus I am enabled to subject the liquid to be puried, sterilized, or aged to successive electrolytic treatments, the apparatus being so designed that the liquid flows after treatment in one vessel into another 6r several others in succession, where it is similarly treated. i

In the accompanying drawings, Figure 1 is avertical sectional view, some parts being in full lines. Fig. 2 is a diagrammatic plan view. In the views, 1 designates a vessel of porcelain, glass, or other non-conductor of electricity andof any suitable form and having a spout l1 near its top. There are vto be sev-' eral of these vessels 1, and they are shown to be arranged one above the other, so that their spouts l can discharge into a metallic funnel 2, which constitutes one electrode supported with its discharging end above the liquidlevel of but so as to discharge into the next vessel below. Arranged in each vessel 1 is an electrode 3, shown to consist of a iiat piece or disk of metal, to .which is soldered a vertical conducting vrod or wire 3a; but surrounding the vertical conducting rod or wire 3 is an insulating-tube 4, of porcelain, glass, or

othersuitable ncnconductor ot' electricity,

extending from thebottom to the top of the vessel. To each of the tunnels 2 lis attached aconducting-wire 5, and all these wires 5 are connected to a main conducting-Wire 6, running to a switchboard 7, containing an appropriate switching device. The tunnels can be insulated from theirsupports by bushings 2, of porcelain, glass, or other suitable non-conductor of electricity. Each oi' the vertical wires 3 in the vessels 1 has coupled to it by means of asuitable coupling device 3" aconducting-Wire 8, and all the wires 8 are connested to 'a main conducting-wire 9. The

. electric current will4 be furnished by any suitable generator or from any appropriate source of electricity. 1

10 denotes a vessel to contain the liquid to be treated and from which the liquid is discharged through a'iaucet 10 into the uppermost vessel 1. As the liquid liows into the lirst vesselY the stream from the tunnel closes the electric circuit from the wire 5 to the wire 8, or reversely, and the stream from the funnel, as well as the liquid in the vessel, is subjected to the electrolytic action due to the passage ot' the current therethrough. -When the liquid in the uppermost vessel rises to the spout l, it :flows into that next below andthe electric current is closed through the next wires 5 and 8, and so on through the entire series of vessels. Furthermore, the stream owing through each ofthe tunnels, because it is small, continuous, and unbroken, is subjected to a higher degree of electric action and. at'the same time is subjected to the action of the ,oxygen of the air. The current of electricity will oi' course be made strong enough to bridge all the streams flowing from the tunnels and the liquid in all the vessels. In this way the liquid as it iiows down through the series of vessels is subjected successively to the action of electricity and air, and because the vessels have their spouts or outlets at their tops the liquid to be treated tarries awhile in each vessel and is more thoroughly agitated and stirred. The treatment is therefore more thorough and perfect.

From the description above given, vtaken in connection with the drawings, it will be seen that I provide for Vpassing a body of liquid in a continuous stream which is controllable in amount from one to anotherlalong a series of liquid receiving and delivering elements or devices each composed of apair of insulated vessels, the primary vessel 2 of each element or device delivering the liquid' to its secondary vessel 1 in a reduced stream, falling through the open atmosphere,

` and each two-part element delivering the liquid to the next and electrically subdividing the stream. as an entirety, supplying to eachV subdivision from a source oi' electric supply currents of electricity 1n multiple arc while the liquid is flowing from one element to thel next in series, the currentin each subdivision passing through one of the parts of the stream which is falling through the open air, the sev IOO eral subdivisions of; the entire stream being equal ,electrically-*that is, with respect to the length ofthe circuit therethrough-and the electric character of the conductor therein for the current.

canvary and control the character and extent of treatment to which it is subject, prolonging or shortening itas desired to meet varying circu Instances. By forming a reduced stream between each primary vessel and each secondary one an'dcausing the current to pass therethrough as part of the circuit I crtract the liquid-path for the current and compelV each molecule to be atfected uniformly. with others, and by causing the stream to drop as a fall from one level to another through the atmosphere, first, I. prevent the non-uniform passage of the current through the liquid, which occurs when ,it is confined Within retainingtubes or vessel-walls, and, secondly, permit the free and quick escape of the undesirable bodies or ated in the liquid during its treatment and for which as vapor there must be free escape.

lI herein-as in the claims, forinstanceT-refer to the fact thatacurrentof electricity passes through theliquid in the vessels of each pair independently ofthe currents passing through the vessels of the other pairs, meaning that` the current which passes through the liquid in any given pair does not also that in any of the other vessels, and hence 9can attain some of the ends above referred to, such as varying the quantity ,of-.current passing through any one of the pairs without affecting that passing through the others.

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