Having Liquid Receptacle Open Upwardly Patents (Class 4/402)
  • Patent number: 7185374
    Abstract: A discharge valve for toilet tanks comprising a flexible ringed hose held by a couple covering a center hole of the toilet tank and a handle connecting to a wire wrapping around an upper part of the flexible ringed hose. The wire connected to the handle bends and submerge the flexible ringed hose into the liquid inside the toilet tank when the handle pulls the wire upwards thereby allowing liquid to enter the flexible ringed hose to flush the toilet bowl. The liquid stops flowing to the toilet bowl when the flexible ringed hose goes back to its original vertical position when the pull on the wire is released and when the level of the liquid inside the tank is below the top opening of the flexible ringed hose.

  • Patent number: 6925658
    Abstract: A flush valve containing a flush drain entrance that while in a rest position is positioned above the water line so that there can be no leakage. When flushed, the entrance falls below the waterline, flushing the toilet bowl and then once again rises to a position above the waterline so that leakage cannot occur.

  • Patent number: 6615415
    Abstract: A tank valve for a lavatory has a body having a plug with a hollow. A flange is formed on a top edge of the plug. A pair of arms is formed on the flange and extends outwards. An upper ring made of a metal is mounted on a top surface of the flange. A lower ring made of a metal is mounted on a bottom surface of the flange. When a user releases a handle, the valve is immediately pivoted downwards to close a water outlet. Thus, a flow-out capacity of water can be controlled by a time of holding a handle, and a lot of water can be saved.

  • Patent number: 5794279
    Abstract: A water saver attachment for toilets being pivotally connected to selectively cover a drain pipe within a flush tank of the toilets. The water saver attachment includes a hollow L-shaped water weight box having a horizontal section with an open top side and a vertical section connected thereto. A support arm is connected to the hollow L-shaped water weight box and a cover is connected to the support arm. The water saver attachment is pivotally connected within the flush tank by a connection device. The water saver attachment is pivotable between a first at rest position in which the cover seals the drain pipe to prevent water from flowing therethrough and a second flushing position in which the water saver attachment is pivoted whereby the cover is pivoted to selectively allow water to flow through the drain pipe. The water saver attachment automatically pivots back to the first at rest position upon completion of flushing of the toilet to limit an amount of water flowing through the drain pipe.

  • Patent number: 5205000
    Abstract: A dual water-level toilet flushing apparatus (10) that allows a toilet user to easily and quickly select either a partial or a full toilet flush. The partial flush which is normally preset is recommended for flushing liquid waste while the full flush is recommended for flushing solid waste. The apparatus (10) which is easily installed and requires no modification to the toilet water tank (60) consists of three major elements: an overflow tube sleeve (12) that attaches to an overflow tube (64) and that has swivelly attached the back end of a floating inverted pendulum (20). The front of the pendulum is attached, via a pendulum/flapper valve link (24), to the front of a toilet flapper valve (30) having its back swivelly attached to the bottom of the overflow tube (64). To effect a partial flush, the toilet flush handle (68) is depressed and immediately released; to effect a full flush the handle (60) is depressed and held for a few seconds.

  • Patent number: 5142710
    Abstract: A water saver being used in the toilet tank and which includes a discharge control and flapper tank ball for controlling the flow of water from the tank or reservoir to the bowl and with the water saver further having a generally cylindrical configuration with an open top and a closed bottom defining a water retaining chamber, with the chamber extending upwardly above the flapper tank ball and being designed to retain a fill of a certain first quantity of water. Pivotal opening of the water saver while tipping a portion of the water outwardly of the enclosure, will not dischasrge any appreciable amount of water so as to permit a more positive seal of the water saver resting on the top of the flapper tank ball which is upon the discharge drain opening.

  • Patent number: 5105480
    Abstract: A pivoting cup is mounted on the flap valve of a toilet. Two flexible actuating elements control the position of the cup. The amount of water used for a flush depends on the orientation of the cup. If the cup is selectively oriented to hold water, a partial level flush can be achieved.

  • Patent number: 4979241
    Abstract: A patented valve control for use in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuating lever and a chain connecting the lever to the valve for opening the latter, includes an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float on the arm biasing the valve to the open position when the tank is full and biasing the valve to the close position when the tank is empty, and a drainable container on the arm biasing the valve open when the latter is open and biasing the valve closed when the latter is closed. The amount of water discharged through the outlet during each flushing operation can be reduced by mounting a flush control device on the arm of the valve control. The flush control device is a rectangular parallelepipedic body with a groove in one side thereof for mounting the body on the arm.

  • Patent number: 4872473
    Abstract: A reversible buoyant and non-buoyant flush tank valve is adapted for use in various types of flush tanks each having different selective valve operating attachments for moving the valve. The valve for use in one type of tank includes an elongated base with opposite end portions with a valve operating attachment selectivity at one end for opening and closing the valve. The other end portion of the valve is selectively attachable to the overflow pipe. The base has opposite sides with a vertically extending hollow frusto-conical cup member on one side. When the valve is used in another type of tank the opposite end portions are removed for connecting a vertical rod valve operating attachment to a first and second oppositely disposed bores to selectively position the cup member upwardly for non-buoyant operation or downwardly for buoyant operation.

  • Patent number: 4841580
    Abstract: A flush valve for use in a flush tank for control by the operator of the amount used in flushing, the valve including an elongate body having a solid generally hemispherical protuberance extending outwardly on one side and a hollow frusto-conical cup member extending outwardly from the other side. A tab and opening therethrough on the forward portion of the body for connection to the valve operating system allows the valve to be alternatively turned with the cup member facing upward and being non-buoyant or having the cup member facing downwardly whereby air trapped therein renders the valve buoyant for substantially a full flush. Spaced arm members extend laterally from the rearward portion of the valve body and have one or more openings pivotally mounting the valve to the normal overflow tube to position the valve with respect to the water outlet in either selected position.

  • Patent number: 4101986
    Abstract: A regulatable flush valve for tank type flush toilets includes a piston-cylinder dash pot, a weighted (fluid filled) plug/valve, a cylindrical overflow tube and a fluid vortex generating element secured in a coaxial arrangement vertically above the outlet of the toilet tank. The piston and plug/valve secured to the overflow tube are lifted from a normally closed position by a conventional pivoting handle mechanism. The piston-cylinder dash pot determines the water volume of a particular flush by controlling the rate of descent of the weighted plug/valve. The vortex generating element works in combination with the walls of the raised plug/valve to generate an energetic fluid vortex as the water flows from the tank into the toilet bowl. The vortex generated by the generating element is complementary to vortex generating elements within the toilet basin to increase washing action in the toilet bowl. The above combination of elements significantly reduces the volume of water required for complete flushing action.
