WATER-PURIFYING APPARATUS.

Specification of Letters Patent.

Patented Feb., 12, 1907.

I Application filed October 3,1906- Serial No. 337,199

can be easily and cheaply manufactured and will readily serve its intended purposes. I Genericall y, my invention comprises means for first mechanically filtering the water as it comes from the supply-pipes to remove those impurities which are in suspension and an electrolytic purifier into which the water flows from the primary filter and wherein it undergoes electrolytic action to precipitate those impurities held in solution; and the invention also comprises a secondary filter into which the water from the electrolytic purifier is discharged and which serves to remove those suspended impurities precipitated by the electrolytic purifier.

My invention also includes an automatic circuit-controller for the electric circuit of the electrolytic purifier, by means of which circuit-controller the circuit is closed by the water-pressure before the water passes into the electrolytic purifier. Means are also provided whereby the electrolytic purifier can be made to operate on the ordinary direct-current-lighting circuit of one hundred and ten volts.

The electrolytic purifier, which forms the essential part of my apparatus, generically comprises an insulating-housing in which is arranged a pair of electrodes so designed and correlatively' arranged as to form a zigzag water-passage from the inlet to the outlet end of the purifier.

With other objects in view than have heretofore been specified the invention also includes certain novel construction, combina tion, and arrangement of parts, all of which Will be described first in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 isa face view of my apparatus complete. 2 is a central vertical longitudinal section of the electrolytic purifier. Fig. 3 is a cross-section on the line 33 of Fig. 2. Fig. 4 is a similar view on the line 4 4 of Fig. 2. Fig. 5 is a central vertical longitudinal section of the circuit-controller. Fig. 6 is a cross-section on the line 6 6 of Fig. 5.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the figures, 1 designates the base-plate, of porcelain, slate, or other suitable insulating upon which the apparatus is mounted.

2 designates a faucet of the ordinary type, which connects with the source of water-supply. .(Not shown.) To the faucet 2 the circuit-controller 3 is secured by a collar 2, as indicated in Fig. 1.

4 designates the primary mechanical filter, which may be of any approved typesuch, for instance, as the ordinary stone filter now in common use. The inlet 4 of the filter 4 is connected, through a preferably flexible pipe 5, with the circuit-controller, while the outlet 4 of the filter 4 connects, through a flexible hose-pipe 6, with theelectrolytic purifier 10, hereinafter referred to.

The outlet of theelectrolytic purifier 10 is connected, through a flexible hose-pi e, with the inlet 8 of a secondary mechanica filter 8, Y

the terminal cord 9 may be led to the source of electric-current supply.

(Not shown.) From the rosette 9 the positive terminal 9 of the electric circuit is led to the sockets of a pair of incandescent lamps 9, arranged in parallel, and from thence ina lead 9 to one of'the terminals 3 of the conductor 3. The other terminal 3 of the controller3 connects, through a lead 9, with the positive electrodes of theelectrolytic purifier 10. The negative electrode of theelectrolytic purifier 10 connects, through a lead 9 with the negative terminal of the rosette 9.

Referring now more particularly to Figs. 2, 3, and 4, it will be seen theelectrolytic purifier 10 comprises ahousing, of porcelain,

formed withshoulders 11 to receive the i housing and a packing-ring 11 as clearly shown in Fig. 2. Theheaders 11 are each formed with a chamber 1] and have their outer surface beveled, as at 11 to fit into thebeveled seats 12 of thesecuringbrackets 12. Thebrackets 12 havecars 12, by means of which they are pivotally secured by screws orbolts 12 to the base 1. Thebrackets 12 have ears '1 2, provided withslots 12 to cooperate with the thumb-screws 12, by means of which thebrackets 12 are retained inposition, Each header 1] is formed with acentral boss 11, in which atubular bushing 13 is held, and thebushing 13 is internally screw-threaded to receive the inlet andoutlet nipples 14, which have a threaded engagement withtheboss 13. A check-nut 14 holds the nipple 1 1 and thebushing 13, as well as a closure or guard-cap 15, in place. Thecap 15 is composed of insulating material and has a central aperture to receive'nipple 14, and a supplementary aperture to permit passage of the terminal leads 9 or 9 as the case may be.

16 designates the negative electrode, which is of substantially comb shape in longitudinal section and provided at each end withlugs 16 to receive thescrews 18, by means of which the electrodes are secured to theheaders 11 and to the lead-wire 19 Theelectrode 16 is provided with a series of equally-spaced comb-teeth orplates 16", preferably wedge shape in cross-section. The space betweenadjacent plates 16 is cut away at 16 to form scum-pockets in which the impurities of the water may collect when they are precipitated. Thepositive electrode 17 is of .the same form as theelectrode 16, being provided with comb-plates 17pockets 17 andlugs 17, as shown. Thepositive electrode 17 is secured to theheaders 11 by screws 19, through the medium of which the lead 9 communicates electrically with the positive electrode. The positive and negative electrodes have their comb-plates 16 and 17 interlocked, as it were, and spaced apart to form a Zigzag water-passage between them from oneend of the housing to the other. Thepositive electrode 17 in practice is formed of aluminium, and I may also form the negative electrode likewise to lighten the construction.

The circuit-controller 3 comprises a metallic housing 3, having a chamber 3 and an inlet-pipe portion 3 and an outlet-pipe portion 3 in communication with the chamber 3 The metallic housing 3 has a threaded shoulder 33 to receive the swivel-nut 3 which abuts the flange 3* of the contact-carrying plug 3, of fiber or other insulating material. Between the plug 3 and the shoulder 3 1 place a sheet of rubber 3 to form a diaphragm, as well as to exclude water from the chamber 3" in the plug 3. The plug 3 has a bore 3", in which the piston 3 operates.

The piston 3 is held against the diaphragm 3" in its projected position by a coil-spring 3 surrounding the stem 3" of the piston 23*.

The plug 3 also has a ehamber3, in which the contacts 3 are secured by the terminal screws 3 and 3 the circuit being closed between the contacts 3 by the contact-bead 3 on the piston-stem 3 which projects into the chamber 3", as clearly shown in Fig. 5. The chamber 3 is closed by a screw-cap 3, provided with air-holes 3" to permit any gases formed within the chamber 3 by arcs or otherwise to escape.

So far as described it will be seen that my invention operates as follows: The operator turns on the faucet 2, which permits the water to flow into chamber 3 of the circuit controller 3 and from thence through pipe 5 into filter 4. The water-pressure within chamber 3 forces the piston 3 inward and brings the contact 312 against the contacts 3 to close the electric circuit to purifier 10. After the water leaves the filter 4; it passes through the pipe 6 intopurifier 10 and undergoes electrolytic purification, after which it passes out ofpurifier 10, throughpipe 17, into filter 8, and from thence is discharged in its pure state for use. The electric current forpurifier 10 serves to light up lamps 9, which may be colored or frosted, if desired.

To clean up my apparatus after the same has become clogged with impurities after long use, it is only necessary to disconnect pipes 6 and 8, remove and wash stones of filters 4 and 8, loosen thumb-screws 12 and swing-brackets 12 in the direction of arrows in Fig. 2, when thepurifier 10 can be removed and theparts thereof separated for cleaning by removingnipples 14 and unscrewingscrews 18 and 19.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the complete construction, operation, and many advantages of my in vention will be readily understood by those skilled in the art to which my invention appertains.
