ELECTRIC WATER PURIFIER.

Application filed May 21,

My invention relates to electrical water purifiers including two electrodes adapted to ie'immersed in water to be purified by an electric current passing from one electrode to the other, and my object is to provide an efiicient device of this character which can be manufactured at small cost and readily assembled or taken apart when it is desired to cleanse the several parts.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is an elevation of the device inserted in a for holding water to be purified. V

Fig. 2 is a vertical central section of the device.

Fig. 3 is a cross section on line 3-3 o Fig. 2.

Fig. 4 is a cross section on line 44 of Fig. 2. I

Fig. 5 is a detail of an insulator having a conductor mounted thereon.

Referring in detail to the different parts, A designates a container which may be of any suitable shape and size and is adapted to hold water to be purified.

2 designates the handle of the device. Said handle 2 is made of suitable insulating material and has an axial opening which is reduced at its upper portion 4 and enlarged at its lower portion 6. v

8 designates an inner electrode which is preferably of rectangular cross section throughout the greater portion of its length and is circular at its upper portion 10 which fits snugly within the enlarged portion 6 of the axial opening in the handle 2, where it is secured by suitable means such as a screw 12 placed through a hole 14 in the side of said handle 2.

16 designates a circular insulator which fits over the circular upper portion 10 of the inner electrode 8 and is clamped between the lower end of the handle 2 and the shoulder 18 formed at the juncture of the rectangular and circular portions of said inner electrode 8. The insulator 16 has a peripheral groove in which asegmental conductor 20 snugly fits and is secured at its ends by screws 22 and 24, to the latter of which a wire conductor 26 is fastened.

The wire conductor 26 extends from any suitable source of electricity, not shown, to the screw 24 through the axial opening in the handle 2, an eccentric opening 28 in the cir-' 1927. Serial No. 193,324;

cular portion 10 of the electrode 8, and a lat cral opening 30 in the circular insulator 16. Another wire conductor 32 extends through the axial opening in thehandle 2 and is se cured to the upper end of the electrode 8 by suitable means such as a screw 34. By arranging the opening 28 eecentrically as stated, sufficient metal is left at one side of said opening for thereception of the screws 12 and'34 without soldering or otherwise securing reinforcements to the circular portion 10 of the electrode.

The segmental conductor 20 fits frictiontight within a tubular outer electrode 36 which is firmly clamped against the lower end of the handle 2 by means of a cap nut 38 consisting' of insulating material and threaded upon the reduced lower end 39ofthe inner electrode 8. In order to prevent the inner electrode 8 from rotating with the cap nut 38 while the latter is being screwed upon the former, I provide the circular insulator 16 with a pair of studs41 which engage two sides of the rectangular portion of said inner electrode 8 as shown by Fig. 3. The outer electrode 86 has longitudinal slots or openings so that water may pass through to the inner electrode 8. i

In order to guard against the user of the device from becoming shocked by touching the outer electrode 36 while they electric current is on, said electrode 36 is enclosed in a housing 42 of suitable insulating material which is clamped between the handle 2 and thecap nut 38. The housing 42 has longitudinal slots 44 for the free circulation of water to the electrodes 8 and 36. i v

46 designates a cover secured to the handle 2 and adapted to rest upon the upper end of the container A and suppopt the device.

In practice when the electrodes 8 and 36 are immersed in water to be purified A. C. or D. C. current flowing from one electrode to the other causes precipitation of the impuri-' ties within a comparatively short time after the current has been turned on. Should any impurities become deposited upon the elec trodes access can be readily had thereto by removing the cap nut 38, which operation permits removal of the housing 42 and the outer electrode 36.

In referring to Fig. 2 it will be noted that the wire conductors 26 and 32 are enclosed within and fully protected by the handle 2,

, the inner electrode 8 and the circular insulator 16, so thatwater cannot reach said Wire conductors and cause a short circuit.

Havmg thus described my invention, What I claim and desire to secure by Letters Patent,

1. A device of the character described consisting of aninner electrode adapted to be immersed in Water Within a container, an outer electrode surrounding said inner electrode and adapted to be immersed in the water, a handle secured to the inner electrode and abutting one end of said outer electrode, a cover for the container secured to said handle, a cap nut threaded upon the inner electrode and adapted to force the inner electrode firmlyagainst said handle, and an in sulating housing adapted to be forced by said cap nut against the handle.

2. A device ofthe character described consisting of an inner electrode which is circular at its upper portion and rectangular at its lower portion, an outer electrode surrounding said inner electrode, a handle secured to the circular portion of the inner electrode and abutting one end of said'outer electrode, a circularinsulator fitting upon the circular portion of the inner electrode and abutting said handle, a conductor mounted upon said insulator and fitting snugly Within the outer electrode, a cap nut threaded upon the inner electrode and adapted to force the outer electrode firmly against said handle, and studs projecting from the insulator and engaging two sides of the rectangular portion of the inner electrode to prevent the latter from rotating with said cap nut.

3. A device of the character described consisting of an inner electrode having a longitudinal eccentric opening at one end for the passage of a Wire conductor, a second wire conductor securedto the thick portion of the Wall surrounding said circular opening, an insulator fixed upon said inner electrode and having an opening for the passage of the first-mentioned wire conductor, a segmental conductor'mounted upon said insulator and to Which the first-mentioned Wire conductor is secured, and a tubularelectrode in which said segmental conductorsnugly fits.

4. In a device of the character described, an inner electrode having a shoulder, an outer electrode surrounding said inner electrode, a handle secured to the inner electrode and abutting one end of said outer electrode, a circular insulator having a peripheral groove and fitting upon the inner electrode at a point between the shoulder thereon and said handle, a conductor mounted in the groove of said insulator and fitting snugly within the outer conductor, and means threaded on the inner conductor for forcingthe outerconductor and. the circular insulator firmly against the handle.

In testimony whereof I affix my signature.

WILLIAM M. MYERS.
