- SPECIFICATION forming part of Letters Patent No. 577,134, dated February 16, 1897.

Application filed Ju1y 2l, 1896. Serial No. 600,015. (No model.)

To all whom it nuty concern:

Be it known that I, JOHN H. HARRISON, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in ater-Pu rifiers, of which the followin g is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar 1'0 numerals of reference indicate corresponding p'arts wherever found throughout both views. This invention relates to electric purifiers for feed-water for steam-boilers; and the invention consists of an improved purifier for I 5 this purpose which involves a suitable casing, which is preferably cylindrical in form, and through which the Water on its way to the boiler passes, said casing being composed of .iron or any suitable metal and being provided 2o with a water-purifier which consists of a voltaic pile constructed as herein described and claimed.

Ihe invention is fully disclosed in. the following specification, of which the accom pan yin g drawings form a part, in which-- I Figure 1 is a central longitudinal section of my improved purifier, showing the water supply and egress pipes connected therewith and also a blow-off or cleaning pipe therefor; and

Fig.

iicr.

In the practice of my invent-ion I provide a cylindrical casing 5, which is composed of iron or steel or any preferred metal and pro- 3 5 titled with caps or heads (5 and 7, and I also provide awater-siipply pipe 8 and an exitpipe 9, and it will be understood that this device is located, preferably, adjacent to the boiler or in any suitable""place, and the exit pipe 9 is designed to convey the water to the boiler, and communicating with the cap or head 7, near the lower side thereof, is a blowoff pipe 10, and each of the pipes S, f), and 10 is provided with a valve-11. I

The voltaie pile or purifier vhich I employ consists of a plurality of circular metal disks 12, three of which are shown in the drawings, and said disks or plates are substantially of the same diameter as the inner diameter of the casing 5 and are provided at theirperimeters with segmental ports or passages 13, and

2, an end view of the voltaic pile or puri similar ports or passages 14 are formed therein, as shown in Fig. 2, the object of this construction. being to provide means for free circulation of the waterfrom one end of the casing to the other. I also provide a plurality of rods 15, any suitable number of which may be .employed,'and these rods 15 are composed of zinc and are passed through suitable openings in the disks. or plates 12, and wound on said rods between the disks or plates are spiral copper coils 16. As thus constructed, it will be seen that the Water flows through the purifier in channels or currents parallel to the elements of the voltaic pile and that a free circulation or passage therefor is provided;

It willbc understood that the rods 15 may be arranged as close together as is possible to place them, or in such mannerthat said rods and the copper coils 16 will occupy the entire space within the casin g, and the ports or passages formed in the disks or plates 12 may be of any desired shape or form and may consist'simply of perforations.

The operation will be readily understood from the foregoing description, when taken in connection with the accompanying drawings, by all those familiar with this class of devices, and it will be understood that anew purifier niay be inserted into the casing 680 whenever desired, or'wherr byreason of the galvanic action which takes place within said casing the zinc rods 15 are consumed. The water passing through the purifier and being subjected to its action, the affinity of the various scale-fprming ingredients in the water for eachother and also their affinity for the metal of the boiler is destroyed, and

no one ingredient can by itself form a scale the non-scaling water is delivered to the boiler, and this result being accomplished the old scale, if any has previously formed on the boiler, will, from the action of the water, rot and decompose and be disconnected from the boiler by the expansion and. contraction thereof, will gradually drop OE, and may be removed therefrom.

Any deposit which may collect at any time in the casing 5 maybe blown off through the tube 10, and although I have described the Icerods 15 and the spiralcoils 16 as composed of zinc and copper, respectively, any other two metals which may constitute an ellfeetire roltaic pile may be employed.

lien in [ully described my invention, I claim as new and desire to secure by l'ietters Patent- 1. In a water p urilier, the combi nation with a suitable easing, of aroltaie pile, consisting of a plurality o'l' disks or plates, which are connected by a plurality of zinc rods which pass t-heretln'ough, said rods being provided between said disks or plates with. spiral. coils of copper wound thereon, substantially as shown and (.leseribcd.

In a water-puritier, the combination with a cylindrical easing, pro-sided with water supplyand egress pipes, of a voltaic pile, consisting of suitable metal disks or plates supporting a plurality oi. longitudinal rods of zinc which are pa ssod ther through, said rods being wound between said disks or plates with spiral coils of copper wound thereon, and

said disks or plates being provided with ports or passages for the water, substantially as shown and descr bed.

v 3. In a water-p11 rifier, the combination with a casing; adjaem'it to and connected with a st eam-boile r, through which casing is passed the '\\'ater-s11pply, of zinc rods passing longitni'lii'ially through said easing and supported therein, each of said rods being separately and spirally wound with copper, substantially as shown and described. 4

In testimony that 1 claim the foregoing as my invention l have signed my name, in pres 'ence of the subscribing witnesses-this 20th day of July, 1896.
