Abstract: Toilet flush tanks run completely empty when the actuating device is actuated briefly. In very many cases this is not necessary. Therefore, a toilet flush tank is proposed where the drain closure part, actuated by a closing force, closes the drain. The closing force can either occur automatically after the water level has dropped accordingly, or it can be released manually when the water level is observed visually.

Abstract: A controlling device for the water-tank of a flush toilet comprising two handles on the water-tank whereby a high or low level is optionally determined, and whose controlling elements are all fitted to the handle assemblies and are independent of a hydraulic backing gate. The invention results in ease of assembling and repair, and also reduced effort for operation of the handles as well as reduced cost for modifications of a conventional water-tank.

Abstract: A water-saving device for toilets is provided which when employed in a conventional toilet tank allows for flushing a conventional toilet employing an amount of water which is substantially less than usually employed. The water-saving device of the invention employs a combination of a lower float and an upper float; upon flushing, the lower float functions as a closure member for the orifice in the bottom of the toilet tank and the upper float is adapted to bear against the lower float to force the lower float to seat in the orifice of the tank after the level of water in the tank has been reduced to 75% or less of the water normally used in flushing a toilet. In addition, locking means and related control means are provided for releasing the upper float when the toilet is flushed and for locking the upper float in an immobile position when the flush has been effected.

Abstract: An improvement is described for a tank type toilet flushing system. A positive coupling is provided between the flushing handle and the tank emptying flushing valve including a rigid flush control rod. This permits the flush to be terminated at will and before the flush tank is completely emptied. The flush control rod has a bent, length adjusting section, and a bent section for removably mounting a float.

Abstract: A normally-open two stage float valve for use with a suction tube leading om a vehicle fuel tank. As the fuel tank begins to run dry it is desired that the float valve close off the tank to the suction force. The valve of this invention includes a float-operated pilot valve element that equalizes forces on the opposite faces of the main valve element as the float moves through its actuation stroke. A lifting head is associated with the pilot valve element for mechanically lifting or lowering the main valve element relative to the main seat when the forces have been equalized.

The invention also is directed to bathroom flush tank covers whenever provided with such a cabinet and to a kit containing such a cabinet and instructions for attachment thereof atop a bathroom flush tank.

Abstract: A flush valve mechanism for controlling the flushing action of water thro the water outlet of a flush cistern is provided. The mechanism comprises a water outlet valve liftable off the water outlet to effect the flushing action and a buoyant, valve-engaging assembly adapted to move independently of the water outlet valve by virtue of its buoyancy. The water outlet valve having an effectively negative overall buoyancy when the cistern is at least partially full. The valve-engaging assembly comprises a pivotably mounted buoyant lever having at least one arm with a buoyant means attached at one end thereof adjacent the bottom of the cistern and is provided with means at its other end for selectively engaging the valve. The assembly further comprises restraining means having a first position normally engaging and restraining the buoyant lever with the buoyant means in close proximity to the cistern bottom and the engaging means in disengaged relationship to the valve.

Abstract: An improved combination commode construction including a water closet common to a plurality of commodes, a plurality of separate commode control assemblies on the water closet, each of which assemblies is associated with a respective commode and is actuatable for effecting flushing of the commode with which it is associated, and flushing apparatus to control the amount of flush water used in the flushing of each commode, the flushing apparatus including a refill water construction for providing refill water to the water closet and the commodes, the flushing apparatus also including a refill control assembly responsive to actuations of each of the separate commode control assemblies for directing and supplying refill water from the refill water construction to the respective commode with which the actuated separate commode control assembly is associated, the refill control assembly being further responsive to actuations of the separate commode control assemblies to inhibit supply of refill water to commodes no

Abstract: A flush valve control apparatus for selectively closing, at the option of the operator, the flush valve of a flush toilet is disclosed. The apparatus includes a control member which is located such that it can selectively push against the flush valve which opens and closes the outlet pipe of a flush toilet. The control member which is normally in a non-control relationship with the flush valve is attached by a hinge to the standpipe such that it may be rotated downwardly until it contacts the top portion of the valve. A rod is pivotally attached to the control member at one end and slidably attached to a line at its second end. The link is attached to the handle of a trip lever, such as is normally found in conventional toilets. On forcing the trip lever downward by rotating the handle in a direction opposite to that for flushing, the link slides along the rod until it meets a stop.

Abstract: An attachment for closing all varieties of flush valves before the normal amount of water has exited the tank includes a buoyant float that falls with the water level of the tank during a flush and applies its weight against the flush valve to push the valve prematurely into its seat. A float guide rod attaches to the tank wall and provides a path for the float to move upon, and a valve actuator rod is adjustably connected to the float and directly contacts the flush valve. A variety of attachments to the flush valves or actuator rod are provided for reliable performance. A combination of an entire flush valve assembly with a valve closer incorporated in its structure includes a float guide rod attached to the standpipe of the valve assembly rather than to the tank wall.

Abstract: A flushing mechanism is disclosed for use in the tank of a toilet, utilizing a spool valve to accommodate various fluid pressures and to accomplish accurate control of volumetric flow. A housing is provided in the toilet tank, defining an inlet port which is adapted to be connected to the source of flushing fluid, e.g. water, and also defining a vertical valve chamber extending somewhat transverse to the inlet port and connected to control the discharge of water from the valve and out of the tank to the toilet bowl. The spool valve is provided in the valve chamber such that the facing surfaces of lands on the spool are subjected to the pressure of the flushing water source, to maintain a balance. Manual means is disclosed for displacing the spool valve to supply flushing water from the source while activating a hydraulic timer which, in due course, resets the spool valve. In the disclosed embodiment, the hydraulic timer involves a bleed tube for supplying water to the tank which contains a float.

Abstract: For use in a toilet flush tank having a flush discharge opening at the bottom which is normally closed by a discharge valve having an air chamber therein, an attachment including an air passage for venting the air chamber and a water level responsive valve normally closing the air passage when the water within the tank is above a predetermined height and for venting the air chamber when the water in the tank falls to a predetermined level, so that when the discharge valve is lifted and buoyed by the air within the chamber thereof during the discharge of water from the tank, the discharge valve will be permitted to reseat as soon as the float controlled valve vents the air chamber.

Abstract: A double valve construction selectively provides a full flush or a partial flush from the tank of a toilet. The apparatus, which may be utilized to modify existing toilet water closets, includes a manifold mounted on the tank in communication with an outlet for draining water from the tank. The manifold includes a pair of valve seats, one located proximate to the bottom of the tank and one located distant from the bottom of the tank. An actuating mechanism selectively operates a pair of valves associated with the valve seats and is so arranged that when an operating handle is turned in one direction, it disengages the upper valve from the upper valve seat for a partial flush and when the operating handle is moved in the opposite direction, it disengages the lower valve from the lower valve seat for a full flush.

Abstract: A dual flush apparatus for selecting one flushing mode in which all the water in the toilet tank is drained or another mode wherein only a portion of the water is drained. A toilet valve actuating handle is bistable so that it is yieldably biased to two positions. It is linked to a toilet flushing valve so that it can open the valve and in one of its bistable positions apply a force on the valve and in the other not apply such a force. Depending upon the particular valve structure to which the handle is linked, the force which the handle applies, when applied either prevents or enables the premature closure of the valve at an intermediate water tank level. One flushing mode occurs when the handle force is applied and the other mode occurs when the force is not applied.
