WATER PURI'FIER.

Application led Hay 28,

This invention relates to improvements in water purifiers, and especially to that type in which an electric current is passed thru the water by positioning electrodes in a circuit in such a manner that when they are immersed in the water and the electric, en* ergy applied, the electric current passes from one electrode to the other thru the water. l

One of the objects ot this invention is to produce a water puriier having electrodes that are provided with means for ad]ust1ng them toward and from each other.

A further object is to provide a water puriier having conical electrodes in axial alignment.

Other objects of this invention are to render the parts accessible, adJustable and removable for any purpose, as well as to provide for their enclosure and protection while in operation. It is also an object of the instant invention to secure ruggedness, durability and simplicity of construction.

The features of this deviceY will be better understood by referring to the accompanying drawing, wherein Figure 1, is an elevation of a water cooler immersed in a vessel of water, and embodying this invention.

im y Fig. 2, is an enlarged longitudinal section Y of the same, taken on line II-II of Fig, 1.

Fig. 3, is a cross-section taken on line III-III of Fig. 2, with parts removed' for clearness.

Fig. 4, is a fragmentary section taken on line IV-IV of Fig. 2.

Fig. 5, is a fragmentary elevation of a modified form of this invention, and

Fig. 6, is a fragmentary elevation showing a further modified form of this invention.

Similar reference characters refer to like parts thruout the several views, and the. numeral 7 designates a longitudinally divided 45 handle, composed of similar handle members 8, adapted to be tted together in Such a manner as to form asuitable handle. Handle members 8 are each provided with an off-set portion 9, which are so positioned as to provide suitable supporting means for two electrodes in axial alignment. In oit-set portions 9 of handle members 8 are recesses 10 which open outwardly and are provided with internal threads at their outer portion for engaging the threads of cap nuts 12 1927. Serial No. 194,982.

Extending from recesses 10 and passing thru the handle members 8 are holes 13 which are suitable for receiving insulated conducting wires 14.

Electrodes 15, which are shown to be of slightly conical shape, and having threaded axial stems 16, are carried by handle members 8 on the inner surfaces ot the oit-set portions 9 by means of threaded stems 16, which pass thru holes 17 in handle members 8, and extend into the recesses 10. For securing said electrodes 15 and handle members 8 in iixed relative position, cap nuts 18 are provided to engage threaded stems 16. rllhe electrodes 15 may be made of any suitable material, and are provided with insulators 19 to insure 'the passage of the electric current from one electrode to the other thru thev water, when the device is in the operative position as shown in Fig. 1. The threaded stems 16 are also insulated fromv the handle members 8 by insulated packing 20, which is inade of very resilient material, such as gum rubber or the like, which permits of considerable compression without destroying its usefulness.

Cap nuts 12 are provided with terminal screws 21 which are adapted to securely hold the wires 14 in contact position. Fitted within the cap nuts 18 are insulating blocks 22 which serve as abutments for holding the electrodes 15 in their proper relative positions. Also interposed between said cap nuts 18 and handle members 8, are gaskets 23.

The portions of the insulated wires 14 contained wit-hin `handle members 8 are protected from the water by means of packings 20, caps 12 and stuiiing boxes 24:.

In order to be better able to properly position-handle members 8, when it is desired to assemble the same, dowel pins 25 have been provided, which are securely attached to one of said handle members 8 and adapted to engage recesses formed in the other handle member 8. When handle members 8 are assembled, they :form a cylindrical handle, the outer end of which is provided with a threaded portion 26, which is adapted t0 receive a threaded ferrule 27, and said liandle is also provided with an annular groove 28, adjacent the ott-set portions 9 ot said handle members 8. Surrounding the ott-set portions 9 of handle members 8, and adapted to engage said recesses 28 is a perforated Lil) split housing, consisting of parte 2.9 and 3Q. Handle members 8 and housing parts 29 and are removably held in operative position Y by means of slip ferrule 31. Housingparts 29 and 30 are also positioned at their outer extremity by any suitable fastening means, as shown at 32, in Fig. 2. e

Encircling electrodes l5 @11d integral with handle members 8, are annular flanges 33, the function of which Will be hereinafter fully set forth.

In Fig. 5, which shows a modified yform of this invention, the perforated housing parts 29 and 30', are shown as integral parts of handle members 8 respectively, While inthe modified form as shown in `Fig. 6, the housing is made of `a single resilient piece of metal formed to the shape of the segment of a circle., and adapted to. engage the annular lianges 33 of the handle members 8 is shawnu iVhen it is desired to disassemble the device, threaded ferrule 27 is iirst removed, then slip ferrule 31 is slipped from its position and over the handle members 8,

Housing Vmembers 29 and 30 lmay then be swung out of engagement with theannular groove 28 in handle members 8, and handle members 8 may ithen be disconnected and free access had to the electrodes 15, and other parts of the device. s

To adjust the electrodes 15 toward and from each other, the cap nut 18 is first removed, then the-cap nut 12 may be a'd-A f justed on the threaded stem 16 of electrodes 15 by which means the distance between the inner surface of said electrode 15 and the head of terminal screw 21 may bevaried, Due to the resiliency vof insulating pacling t 20, against which cap nut 18 is abutted, the

electrode will be held in its extreme outer position until the cap nut 18 is screwed into its seated position, when it will force said electrode 15 to a predetermined position, which is dependent upon the relative positions of lock nut 18 and electrode 15. It is Vapparent that this axial adjusting may be made on either or b oth of said electrodes 1 5. y

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. In' a device of the character described,

tWo electrodes, a longitudinally divided handlevcarrying the same, means carried by said handle to move said electrodes toward and from each other, a perforated housing enclosing said electrodes and means for removablyfsecuring together the members of said divided handle and said housing.

2. Inl a device of the character described,

vand means carried by said. handle to move said electrodes toward and from each other.

4. ln a device of the character described, a plurality of electrodes in axial alignment, a longitudinally divided handle carrying the same, means carried by said handle `for moving said electrodesV toward and from each other, hermetically sealed passage-Ways extending thru said divided handle to receive electric conductors extending .from the elec trodes to the opposite end of the handle and means removably securingsaid divided han.v die in an operative position.

5, rIn, a device of the character' described, two conical elctrodes positioned in axial alignment, a longitudinally divided" handle carrying the saine, meansicarled by Said handle to move said electrodes toward and from each other, passage-Ways extending thru "said handle, electric conductors ex? tending from the electrodes to the opposite end of the handle thru each passage, a'. perforated housing covering said electrodes and means for removably securing said divided handle and housing in fixed relation;
