PATENT OEEICE.

WALTER H. GREEN, OF CHICAGO, ILLINOIS, ASSIGNOR TO KENNICOTT VVATER-SOFTENER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION oF ILLINOIS.

WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 767,746, dated August 16, 1904.

Application filed April 15, 1904.

'l T0 a/ZZ whom, t may concern:

zen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a new and useful Improvement in WaterfPuriers, of which the following is a specification.

My invention relates to the means employed in water-purifying apparatus for automatically supplying the chemical solution in predetermined proportion to the water to be treated for softening or purifying the water, thereby better to adapt it for industrial purposes; and it relates particularly to an improvement upon the apparatus for the purpose stated set forth in United States Letters Patent No. 732,357, dated June 30, 1903, to Cass L. Kennicott.

My object is to provide an improved con-l struction of the mechanism actuated by the tilting receptacle to feed to it the predetermined proportion of the chemical solution from the holder thereof, thereby, particularly with reference to the device of the aforesaid patent, to increase the capacity of the holder and to simplify its construction and operation.

In the accompanying drawings, Figure 1 shows my improved apparatus in front elevation with parts represented by dotted lines, and Fig. 2 is a section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow.

A is the tank or holder for the chemical solution, shown of general cylindrical shape, and it is usually connected for supplying it with a chemical-mixing tank (not shown) such as is commonly provided in apparatus of the classk to which my improvement relates. Adjacent to the base of the holder is journaled on a suitable support c@ to rock on its center the tilting receptacle B of the preferred scoop form illustrated, with a central vertical partition I) within it, dividing it into compartments c and c'. The water to be treated enters the receptacle B from a valved supply-pipe C.

A rope d, chain, or other suitable flexible mediumis fastened at its ends to the opposite ends of the receptacle B, passing therefrom over two sets of pulleys e e and e e', journaledon sup- Serial No. 203,324. (No mdel.)

down into the latter between the pulley sets I about a guide-sheave g, journaled in the holder near its base. On the rope (l, within the chemical-solution holder and preferably on each length thereof, as shown, is fiexibly fastened a cup L, the capacity of which should be suitably proportioned to that of each compartment in the tilting receptacle to be filled by lowering it from the contents of the holder A and discharged when raised over the upper edge of the latter into a hopper c', from which a pipe 7c leads downward to the receptacle B. Guides are provided, one foreach cup, in its movements, that shown in Fig. 2 comprising a pair of parallel longitudinally-slotted bars Z, fastened in proper position to the inner surface of the wall of the holder to eXtend'vertically therein and beyond its upper edge, over which each bar is arched toward the hopper. The cup is hinged at' its lower edge to the rope and has lateral studs confined in the slots of its guidebars Z, whereby as the filled cup is raised to the position of that shown in Fig. 2 and by the full lines in Fig. 1 it is turned to empty its contents into the hopper z'. A shield n is provided foreach cup to extend over it, being supported for that purpose in the tank on the rope Z therein. This shield tends to prevent, in settlement of the solution in the tank, the deposit of particles in suspension into the cup, which would unduly increase the strength of its contents, and during the period that the apparatus is out of operation the shield prevents such a deposit in the cup as would tend to clog it therewith. As the water to be treated flows into the receptacle B from the pipe C it fills the compartments of the receptacle alternately, thereby rocking it and discharging into a tank (not shown) for the water undergoing treatment the one compartment while the other is filling. This rocking motion of the receptaclel actuates the rope l alternately to lower and raise the cups /L L, whereby the contents of each are introduced into the respective compartments of the tilting receptacle before they become filled with the water to be treated.

The gist of my improvement consists in so connecting with thel tilting receptacle the cup or cups as to adapt the latter to be moved vertically in the chemical-solution tank. This enables me to increase the capacity of the solution-tank over that of the aforesaid patent, since it permits the base of the tank to be flat instead of rounded, and the construction is much simpler and materially cheaper to produce than that of the patented apparatus, because of the regular form permissible for the solution-tank, of the omission of the conduits for conducting the solution to the tilting' receptacle, and of the rock-shaft and link connections between the holder and receptacle, while the friction due to those connections and that of the cups against the sides of the holder is dispensed with, thus enabling the apparatus to run more easily.

While the means shown and described for embodying the aforesaid gist of my improvement are thoroughly practicable and desirable, it may be embodied in other forms. Hence I do not limit my invention to the particular form of its embodiment herein set forth.

What I claim as new, and desire to secure by Letters Patent, is-

1. rlhe combination with a chemical-solution holder of a water-purifying apparatus, of a tilting receptacle supported to be rocked by the weight of the water to betreated flowing into it, cup raising and lowering mechanism connected with said receptacle to be actuated by its movement, and a cup supported in said holder by said mechanism to be thereby vertically raised bodily above the liquid-level in the holder and lowered therein.
