To f1.7/ i/'m/ii. it vim/y con/cern.:

Be it known that l. B nn'r B. Sos-mim, a citizen ot' the United States, residing at (.lhicago, in the conntwv ot Cook and State ot' Illinois, have invented a new and use'tul lmproveiiient in lVater-lurit ving Apparatus, ot' which the Vfollowing is a specilication.

.\l v invention relates to an iiiiproveiiientiii that part ot apparatus Vtor purifying water t'or industrial purposes` bv softening it with chemicals which proportions the tpiantitv ot' the chemical solution employed to the raw water to be treated.

M v primar)v object is to provide a construction ot' rotary valve device. to be actuated b v the power ot the llow to the' apparatus otl the raw water to be treated to suppl)v to the water the proper proportion ot' the chemical solution for treating il'.

"lo this end niv invention consists in the valve device combined with water-softening apparatus` to produce the aforesaid result; and it also consists in details otl construction and combinations otl parts, all as hereinafter described and claimed.

Referring' to the accompanying drawings, Figure 1 isa broken view in elevation, partly sectional, in the nature of a diagram, showing water-softening apparatus equipped with mv improvement; Fig. 2. a broken view showing the valve device in longitudinal section with the ports ot' the valvc` in one ot theirtwo operative positions', and Fig. 3, a similar view ot' the same, showing the valve-ports in their other operative position.

1 is the valve device, comprising as its preferred construction (representei'l in Figs. 2 and 3) :i casing. containinga tapering bore tormterminate. respectively, in the openings 3, -1, and and pipes 16 and 17 terminate, respectively, in the openings 6 and T ot' the easing.

lVitli the valve S in the position represented in Fig. Q the ports 9 and 11 areclosed b v the casing-wall, while the port 10 connects the pipes 11 and 1G and the port 12 connects the pipes and 1T, and a halt-turn ot the valve in its seat to the position represented in Fig. 3 causes the port E) to connect the pipes 13 and 16 and the port 11 to connect the pipes 11 and 1T and brings the ends ot' the ports 10 and 12 against the casing-wall to close them while the pipe l5 is out ot' coincidence with a valve-port and is closed bv the valve.

Fig. 1 shows a preferred manner ot' utilizing the valve device otl the described consti'uction coiiperatively in two situations in a water-puritving apparatus. At ,18 is represented a precipitilting-tank containing bailleplates 1t), to which the water to be purilied in it is ted at'ter being mixed with a suitable clieniicil solution, (say ot' linie or soda,) with a supply ot' the mixture, which in the arrangement illustrated is obtained from two similar mixing-tanks 2O and 21. A valve dcvice 1 is interposed between the precipitatingtank and the mixing-tanks, with its pipes 13 and 15 discharging downward into the tank 18 and its pipes 16 and 1T respectively coinniunicating with the mixing-tanks 20 and 21, while the pipe 1-1 serves for conducting to the apparatus the llow from an)Y suitable source (not shown) ol the raw water to be treated. (.)n the stem end 22 ot' this rotar)P valve are secured a pinion Z2-l and a sprocket 2f-1. A levei 25 is t'iilerlimed centrally at 2(3 between the mixing-tanks to adapt it to be i'ocked on its Vt'iilcriim under the action ot' a weight 2T. movable, as by rolling, between stops Q8 Q8 on the lever near its opposite ends, and an arm 22) depends troni the lever and terminates in a segmental rack 30, engaging the pinion 23. ln the mixing-tanks 2() and 21, respectively, are the floats 31 and 32, each supported on an end ot the lever 25 b v a bent arm 3?), sti'addling the edge ot' the tank. and pivotally connected at its inner end with the float and similarly connected at its outer end with the lever. Above the plane otl the mixing-tanks is supported a ehemical-solution tank 34:, having ioiiriialed upon it a rock-shaft 35, carrying stirrers 36 36, depending into the tank,

and a belt-pulley 37. Below the solution-tank is supported another valve device 1, with its pipes 13 and 15X, (corresi'ionding with the pipes 13 and 15 of the lower valve,) communicating, respectively, with the mixing-tanks 2O and 21 and with its pipe 14X, (corresponding with the pipe 14 of the lower valve,) communicating with the solution-tank. The pipes 16 and 17X, which correspond, respectively, with the pipes 16 and 17 of the lower valve device, are each equipped with a liap-Valve 38 for the purpose hereinafter explained, and each has a flexible section, preferably of rubber hose, 39, interposed between rigid sections of a pipe, the upper sections of the pipes terminating in inwardly-opening checkvalves 40 40 and being adjustably supported by clamps 41 4l on vertical rods 42 42, depending from the solution-tank. The upper valve device 1 carries on its stem end a sprocket 43, connected by a chain 44 with the sprocket 24, and the pulley 37 is connected by a belt 45 with a smaller belt-pulley 46 on the stem end of the valve of the upper valve device 1.

The operation is as follows: Assuming, for starting, that the parts of thelower valve device 1 are in the relative positions shown of the valve represented in Fig. 3 and that the parts of the upper valve device are in relative positions shown of the valve represented in Fig. 2, raw water flowing through the pipe 14, port 11, and pipe 17 enters the tank 21 and eventually lifts the iioat 32 therein, with the result of raising the adjacent end of the lever 25 and causing the weight 27 to move upon it and assist in depressing it toward its opposite end. At the same time chemical solution iiows from the tank 34,through the pipe 14 and the respective valve-port 10, into the pipe 16 and flexible section 39 thereof, fill-l ing the same to its check-valve 40 and closing the latter by the pressure of liquid against it. Meantime turning the valve of the lower valve device 1 is proceeding with the movement of the lever 25 on its fulcrum by engagement of the rack 30 with the pinion 23, and the sprocket connection between the two valves simultaneously turns that in the upper valve device until they occupy positions in their casings relatively reversed from those described, wherein raw water from the pipe 14 flows through the port 10 and pipe 16 into the tank 20, and solution from the tank 34 discharges through the pipe 14X, respective port 11 into the pipe 17X and lits flexible section 39, filling the same to its check-valve 40 and closing the latter by the pressure of liquid, and the contents of the tank 21 dischargeinto the precipitating-tank through the pipe 17, valve-port 12, and pipe 15. lith these ports in the valve of the upper valve device in the positions represented in Fig. 8 the contents of the pipe 16X above the dotted line at 47 discharge through the port 9 and pipe 13 into the tank 2O when the float therein is down, and in discharging opens the respective check-valve 4() to facilitate the flow and the respective Hap-valve 38 to vent the pipe 16 and prevent siphoning of that portion of its contents below the line 47, and with the ports in the upper valve device in the positions represented in Fig. 2 the contents of the pipe 17 above the dotted line at 47 discharge through the port 12 and pipe 15 into the tank 21 when the oat therein is down, and in discharging opens the respective checkvalve 40 to facilitate the flow and the respective flap-valve 38 to vent the pipe 17X and prevent siphoning of that portion of its contents below the line 47.

As will be understood in starting with filling raw water into, say, the tank 21, as described, the firstcharge of water in that tank will discharge without the addition to it of any solution; but thereafter chemical solution will enter the tank 2O from the pipe 16 each time the iioat 31 descends, and the solution will enter the tank 21 from the pipe 17 each time the float 32 is down.

Though the upper and lower valve devices are alike in all particulars, the ports in the upper valve may be of smaller diameter than those in the lower one, because the quantity of the liquid which passes through the Lipper' valve is less thanthe quantity of the liquid which passes through the lower valve.

The flexible construction of the pipes 16 17X adapts them for regulating the proportion of the chemical solution to be fed to the mixingtanks, since by raising the pipes, which are held in their adjusted positions by the clamps 41, the quantity to be discharged from them may be increased, and by lowering them the quantity to be discharged may be decreased, according to the particular requirement for the raw water to be treated and the quantity thereof admitted for each charge into a mixing-tank.

The number of the ports in the valve ofthe device 1 may be any that is desired, thus one or more, without departure from my invention. Thus the valve device may be used for the raw water alone or for the solution alone and some other suitable proportioning means may be substituted for the valve device in one position, and if only one diagonal port is provided in the valve to connect two diagonally opposite openings in the valve-casing obviously there can only be a passage of liquid in IOO one direction through the valve in one of the Y acter described, the combination with the precipitating-tank and a mixing-tank, of a valve device, a discharge-pipe leading' from an opening in the valve device to the precipitating'- tank and a pipe connecting' another opening' in the valve device with the mixing-tank` and a supply-pipe for the water to be treated leading' to another opening' in the valve device, 1
