Specification of Letters Patent.
Application filed March 10, 1909. I Serial No. 482,539.
To all whom it may concern Be it lmown that 1, JAMES L. Goucnnn, a citizen of the United States, residing at New York, New York county, New York, have invented new and. useful Apparatus for Electrolytic Purification of Liquids, of which the following is a specification.
This .invention relates to the handling of a substance to be treated, and more especially to combining electrical and mechanical action in treating the substance.
This invention has utility when embodied for the treatment of food, as milk," which it purifies, sterilizes and generally improves all the qualities thereof, particularly making more digestible, more uniform, and of seemingly finer texture or grain.
Referring to the drawings: Figure 1 is an elevation,.with parts broken away, of an embodiment of apparatus involving the invention in a milk treating mechanism, the door to the structure being open; Fig. 2 is an elevation of the opposite side of the structure from the showing of Fig. 1, with the door thereto also open; Fig. 3 is an enlarged section view on lineTTlL-Tllll of Figs. 1 and 2; Fig. 4 is an enlarged detail in section of the valve controlling the current flow ormechanical feature of the invention; Fig. 5 is another view of the valve partly in section at right angles to showing in Fig. 4; and also showing float; Fig. 6 is an enlarged medial vertical section, with parts broken away of the structure of Figs. 1, 2 and 3; Fig. 7 is a medial vertical section of a form of electrode in itself adjustable, the view being similar to that of Fig. 6; Fig. 8 is a bottom plan view of insulator closing the lower portion of the electrode of Fig. 7; Fig. 9 is a plan view of shelf of Fig. 7, on a reduced scale; Fig. 10 is an elevation with parts broken away of a milk treating mecha nism in which the varying of the distance between electrodes is brought about by ad- 'justing theshelves; and Fig. 11 is a section in reduced scale on the line X][Xl[ of Fig. 10.
The substance to be treated, herein being disclosed as milk, is conducted from the storage tank 1 through line 2 to the treating mechanism 3, having the door 4, shown in Fig. 1 as open. The rate of flow of the milk from pipe line 2 into the mechanism is controlled by float valve 5, which serves to keep the liquid in the mechanism always under a constant head, thereby insuring a uniform rate of flow. The reservoir 6 into which the milk is discharged from valve 5, is located on one of the shelves 7 of the mechanism. These shelves 7 have openings 8 therein permitting flow of the milk from the bottom openings in reservoirs 9 successively.
In each reservoir 9 is an upwardly facing bowl, zone walled, doubly curved walled, or concave receptacle 10 into which the milk falls from reservoir 6 or 9, and'overflowing into the reservoir proper itis conducted through spout 11 into oppositely directed bowl or concave receptacle 12, the ball valve controlled vent 13 permitting initial filling thereof, while the spout 11 may operate as a siphon in emptying vessel or reservoir 9, as the milk passes through the perforation in the insulator 1 1. The insulator closes the lower side of the receptacle 12, while the opening therethrough is equally spaced from the concave walls of the receptacle. his opening or perforation registers with the opening 8 in the insulating shelf 7.
The opposite side of the mechanism 3 from that having the door 4, is equipped with a door 15 inclosing the electric terminals. This door is mounted on mechanism housing by the hinges '16. The reservoirs 9 together with the hemispherical receptacles therein serve as electrodes, one vessel being equipped with electrical terminal 17, the next with terminal 18, the following with 17, etc., the terminals 17 being connected to main 19 and the terminals 18 to main 20 of opposite sides of an alternating current circuit, shown as stepped to suit the conditions by transformer 21.

minals or where the li uid becomes a conductor. The configuration of the device of the disclosure accomplishes this end by diffusing the electric current over the bowlshaped electrode to charge the stream, which mechanical current or stream is subsequently congested or restricted by perforate insulator, to at this point bring about maximum electrical carrying capacity of mechanical liquid stream, which as shown is at'the point of maximum stream flow rate. On striking vessel 10 centrally, there is here also avoided any electrical localization which might tend to decompose the substance treated or objectionably coat the terminals, for there is the same difl'using of the current to the hemispherical equi-distant' walls of the receptacle. By so handling, the electric current converges toward and diverges from the hemispherical faces of the electrodes, there is no excessive electrical heating of the substance treated and still electrical density suificient to treat is produced.
To adjust the treating, the mechanical flow or electrical current may be varied, or the number of intervals of the electric current action changed by disconnecting one or more of the series of electrodes. -Again,.adjustment may be brought about by changing the distance apart of the electrodes, so that length of maximum electrically charged stream may be shortened or lengthened. In Fig. 7 this change of stream length is brought about by the adjustable electrode. Liquid overflowing from bowl 23 into reservoir 9 is drawn off through siphon spout 24:, of bowl 25. The bowl 23 has a screw thread connection with the bowl 25. The bowl 25 forms a common electrode with the reservoir 9. The collar 26 fast with insulator 27 seals the receptacle 25, the collar 26 being screw threaded while the insulator 27 is shouldered to permit use of gasket 28. These elements are thus firmly locked inassembled relation. That there may be ready rotation of insulator 27, recesses 29 are provided i therein. Opening 30 in shelf 31 allows of placing the assembled electrode and reservoir in position, the shelf and structure proper also being of insulating material. In
general assemblage, Fig. 10 shows this adjustment of the electrodes relatively to each other by varying the positions of the reservoir carrying shelves. From the supply tank32, the liquid passes through pipe line 33 through float valve 34 into tank 35 mounted on the-treatingmechanism structure 36. The constant volume stream, because under constant head, flowing from tank 35 falls into concave receptacle 37 from which it overflows into reservoir 38, thence through the three spouts 39 into receptacle 41 having the vent 40, and then out through perforate electrode 42 into bowl shaped electrode 37, then passinginto oppositely directed bowl shaped electrode 41 as the successive stages of the treatment occur.
The maximum electrically charged and maximum velocity portion of the stream is that from the inverted bowl through the perforated insulator to the upright bowl. The larger cross-section of the stream in the bowls is the region of minimized stream velocity as well as minimized electrical action and here occurs a general mixing or commingling of the general mass of the substance to insure a uniform treatment. The reservoirs into which the bowls overflow render increasingly effective the mixing action and serve thus to add their larger capacity to the eddies in the reservoirs of the bowls.
' In the disclosures herein there is provision for carrying on as a continuous process a most, sure treatment. There is flexibility as to regulation and adjustment to meet varying conditions of material for operation desired or found most expedient. By inclosing the structures, contamination of the substance treated by the surrounding air is avoided. Further the liquid is not accessible to operatorsor attendants, nor are the electrically charged portions exposed to permit of any danger from accidental handling.
