WATER-PURIFYING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 767,698, dated August 16, 1904.
I Application filed December 5, 1903. Serial No.l83,864=. (No model.)
To all whom: it may concern:
, Be it known that I, CAss L. KENNIcOTna citizen of the United States, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improve ment in VVater-Purifying Apparatus, of which the following is a specification.
My invention relates particularly to waterpurifying apparatus of the character disclosed in Letters Patent No. 665,606, granted to me January 8, 1901.
My primary object is to provide a substitute for the swinging pipe-section employed in connection with the float mechanism of said patented construction, the new construction possessing certain advantageous features, such as simplicity of construction and compactness. Incidentally it will be noted that in the new construction variation in the head of pressure at the discharge-orifice of the hard-water tank (supplying the water-wheel) is accompanied by variation in the area of the discharge-orifice of the chemical-solution (such as solution of soda) tank.
My invention is illustrated in the accompanying drawings, in which- Figure 1 represents a broken vertical sectional view of water-purifying apparatus embodying my invention; Fig. 2, a broken bottom plan view of the chemical (soda) solution tank employed; and Fig. 3 an enlarged sectional View taken, as indicated, at line 3 of Fig. 2.
In the preferred construction, A represents a mixing-chamber located in the downtakeconduit A of water-purifying apparatus of well-known general construction; B, amotorcasing surmounting the mixing-chamber; B, a water-wheel insaid casing; B a'stirrer operated from the water-wheel; C, a hard-water tank provided with a discharge-spout a; C, a supply-pipe connected with a hydrant, (not shown;) D, a chemical-solution (preferably solution of soda) tank provided in its bottom witha discharge-orifice I); D, a source of supply for the tank D, from which source liquid is admitted automatically to the tank D by a float-controlled valve D D a conduit leading from the tank D to the mixing-chamber;
E, a horizontally-disposed slide or gate controlling the orifice 6; E, a Weight attached by a cord 0 to one end of said gate, said cord passing over a pulley c in substantial alinemerit with the slide, and E a float operated by water in the tank C and connected by a cord 0 with the adjacent end of the slide E, the cord passing about a,pulley c in substantial alinement with the slide.
The orifice 5 comprises a slot having converging sides, the large end of the slot being toward the pulley 0 The slide is reciprocable in guides d, extending longitudinally of the slot 6. The conduit D has an enlarged admission end f, located beneath the slot 6.
In operation water to be purified is contained in varying depth in the tank C, limewater wells up into the mixing-chamber in a well-understood manner, and the tank D is supplied with chemical solution at a constant level. The water-wheel which serves to operate the stirrers and to supply any other necessary power is operated by the water entering the machine from the tank C. The quantity. of hard water entering the machine, passing the wheel, and entering the mixingchamber varies with a variation of the head of. water in the tank C. As the slide E is connected with the float E the slide is drawn to the right, decreasing theorifice b as the float descends, and the slide is drawn to the left by the'weight E, increasing the size of the orifice as the float E ascends. Thus it follows that asthe discharge of hard water from the tank C increases the discharge of chemical solution from the tank Dincreases. Since the flow from the orifice a does not increase in direct proportion with the increase of head in the tank C, it is desirable that the orifice b shall not increase in size in direct proportion with the movement of the slide. Hence the reason for tapering the slot 6. It is a simple matter to properly design the opening 5 to secure always the proper ratio between the hard-water and chemical solution entering the mixing-chamber.
From the foregoing explanation it will be understood that the ratio between the hard Water and chemical solution entering the mixing-chamber is preserved solely by a variation of the area of the discharge-orifice of the chemical solution tank approximately with the variation in the head of water in the hardwater tank. Obviously minor details of construction within the spirit of my invention may be made.
What I regard as new, and desire to secure by Letters Patent, is
1. In apparatus of the character described, having a mixing-chamber, a water-supply tank having a discharge thereinto, a liquidsupply tank having in its bottom an elongated discharge-orifice communicating with said mixing-chamber, and afloat operated with a variation in the height of water in said water-supply tank, afloat-actuated horizontallymovable slide having a guide extending longitudinally with reference to said elongated orifice, for automatically varying the size of said discharge-orifice with a variation in the head in said water-supply tank, for the purpose set forth.
2. In apparatus of the character described, having a mixing-chamber, a water-supply tank having a discharge thereinto, a liquidsupply tank having a discharge-orifice communicating with said mixing-chamber, and a float operated with change in level in said first-named tank, means for automatically varying the size of said discharge-orifice with a variation in the head in said water-supply tank, including a float-actuated slide controlling said discharge-opening, the dischargeorifice of the second-named tank tapering to insure the proper proportionate discharge, for the purpose set forth. I
3. In apparatus of the character described, having a mixing-chamber, a hard-water-supply tank, and a liquid-supply tank, in combination with means for varying the effective discharge-orifice of said second-named tank, comprising a horizontal discharge-orifice for said second-named tank, a horizontal gate therefor, potential means for moving said gate in one direction, and a float actuated with change of level in the first-named tank and serving to actuate said gate in the other clirection.
4. In apparatus of the character described, having a mixing-chamber, a hard-water-supply tank, and a liquid-supply tank, and means for varying the effective discharge-orifice of said second-named tank, comprising an elongated discharge-orifice in the bottom of said second-named tank, a gate controlling thesame and movable longitudinally thereof, a Weight serving to actuate said gate in one direction, and a float in said first-named tank serving to actuate said gate in the other direction, for the purpose set forth.
