' VALVE Filed Sept. 28, 1931 IN VENTOR Z sv/s-Lflozuzvsfi ATT NE'Y Patented Dec. 6, 1932' UNITED STATES PATENT OFFICE LEWIS L. IDOILILIlll'GrEIR, OF ROCHESTER, NEW YORK VALVE Application filed September 28, 1931. SeriaJNo. 565,521.

vantages will become more readily apparent P from a detailed description of the invention which follows, reference being had to the accompanying drawing in which Figure 1 shows a sectional view of a flushing tank equipped withmy improved drainage valve.

'F gure 2 is a detail sectionalview of a modified form of one of the valves.

The valve mechanism and'inlet for filling the flushing tank form'no part of my invention as any of the usual types of filling mechanisms may be used in connection with my drainage valve. The filling mechanism of the tank is therefore not illustrated and described. I

In all water closets the water tank is completely emptied every time the closet is flushed. This is a waste of water whenever the closet is used as a urinal. because in that case only about one-third of the volume of water in the tank is necessary to sanitarily flush the closet; Two thirds of the volume of water of the tank is thus wasted. The increase in the water'consumption in most of the growing cities has in many cases taxed the water resources to t e limit-and means are constantly sought to ther increase the water supply or effect a saving of the existing vwater supply. It is believed that with the use of my'present invention many gallons of water would besaved in each household without in any way jeopardizing the sanitary function of'th'e water closet.

As illustrated in the accompanying drawing the saving of watcris effected by the use of a double drain valve which is used in place of the single drain valve now universally used on-the outside of the tank.

' chamber are provided the openings 6, 6 which -chamber 5 w ile the sleeve valve is-held telein combinations with all water closets. This double drain valve is operated by the 'same operating mechanism as that used for op erating a single drain valve and is manipulated by a suitable turning handle -1- located 55 The motion of this handle is transmitted to-a lever arm 2 pivoted on the inside ofthe tank so that this f lever canbe raised at will; By means of r Y this turning handle 1 and lever 2 the double 0 drain valve is operated to either drain all or but a part of the tank 3 for flushing puroses. 4

I The double drain valve'comprises the hollowrubber valve member 4 which is'suitably attached to the open bottom of the cylindrical chamber 5. In the cylindrical wall of this permit water to enter the chamber 5 and hollow valve member and pass out thru the opening 7 in the center of the bottom of the valve member. The valve member 4 is adapt- I ed tobe seated on the valve seat 8 which surrounds the outlet 9 leading'to the water closet- 10. In this way water passing thru the valve member 4 while it is seated on the valve seat '8 will flush the closet the same way as water entering directly into the outlet 9' on the raising of the valve member 4 from the valve I seat 8 Y I The water entering the openings '6, 6 in the cylindrical wall of the chamber 5 of the valve member is controlled by a sleeve valve 11 which telescopes .over the cylindrical chamber 5 and is provided at the open end with a flange 12 which is adapted to seat itselfon theannular shoulder 14 of the valve member 4 to provide a seal between the gasket'and shoulder to revent water from entering the sco ed over-it.

uitably attached to the upper endofthe sleeve valve 11 is a hollow and externally threaded stem 15. .This stem isclosed at the top and has the float member 16- threaded thereonso that it can be vertically adjusted on the stem for a purpose thatwill presently appears A nut 17, threaded to the stem 15,

serves as a shoulder which is engaged by the link 18 carried by the leverarm 2 when the latter is raised on'the operation of the turning handle 1. In this way the raising of the lever arm 2 by the handle 1 effects first a raising of thelstem 15 with its float .16 and sleeve valve 11. This unseats the flange 12 from the shoulder 14 of the valve member '4 and ermits the water from the tank to enter t e openings 6. 6 in the side of the cylindrical valve chamber 5 and pass thru the valve member 4 into the outlet 9. For this operation of the sleeve valve 11 the valve handle is only partially operated and as soon as the valve 11 is open it is held open by the action of the float member which keeps the sleeve valve elevated until the level of. the I water within the tank is lowered-and the float has dropped to a point where the sleeve valve suspended from it again closes the openings 6, 6 in the valve chamber 5, By adjusting the float member 16 on the hollow stem 17 the;

water in the tank may thus be drained by the sleeve valve 11 to a predetermined level and in this way a portion of the water or the tank is allowed to enter the outlet 9 with practically the same pressure or head as water from the tank will enter the outlet 9 after the valve member 4' is unseated. The

practically eliminated because after that the float continues to raise the valve until it is a fully opened.

' The movement of the sleeve valve11 on the cylindrical valve chamber is limited by one or more stop pins 19 which are carried by the sleeve valve 11 and project into the guide slots 19A of the valve chamber 5. The sleeve .valve 11 in its individual operationin I this way can slide up on the valve chamber 5 only until the pin 19 engages the upper end of one of the guide slots 19A of the valve chamber 5. Raising the sleeve higher than this on a continued movement of the handle 1 and its lever 2 will therefore effect a raising of the valve chamber 5 and its valve member 4 and will unseat the valve member 4'from I the seat 8 and allow the water from thetank to enter the outlet 9 without first passing thru the valve member 4. 7

As illustrated in Figure 1 the valve member 4 which is preferably made of rubber has incorporated therein afloat chamber 22 which'surr'ounds the hollow center portion thereof; This float chamber serves to give the valve member sutficient buoyancy to rise with the valve chamber 5 after the valve member has been unseated as above described. In rising, the valve chamber telescopes into the sleeve valve 11 and remains therein un-. til the falling water level in the tank has dropped to a point where the float chamber 22 of the valve member -no longer can keep the valve member from seating itself on the seat 8. To guideand prevent the valve chamber 5 from binding within the sleeve valve 11, a guide pin 23' is provided on top of the valve chamber 5. This guide pin engages the hollow stem 15 of the sleeve valve and guides the pin in a straight line movement.

In Figure'2I have illustrated the valve member 4 surrounded by a suitable casing 24 in which suflicient air'will be trapped to provide the necessary buoyancy for the valve member without the aid of a float chamber such as is illustrated in Figure 1.

From the foregoing it will be apparent that I have devised a new and useful drain mechanism for either partially or whollv emptying the contents of a tank with practicall the same head or pressure, vand while I have. in the present instance" shown one embodiment thereof which will give in practice satisfactory results, it is to be under stood that this embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
