Abstract
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. A slot extends into the groove from one end of the body for facilitating mounting of the body on the arm. The body changes the turning moment on the arm to close the valve before all of the water has been discharged from the tank. Thus, the quantity of water discharged from the tank to the toilet bowl during each flushing operation can be reduced.

Claim 1
Independent Claim
295 words
A flush control device on a valve control in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuation lever and a chain connecting the lever to the valve for opening the latter, the valve control including an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float connected with the arm biasing the valve toward the open position when the tank is full and biasing the valve toward the closed 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 flush control device comprising body means adjustably mounted on said arm between said float and said valve for variably adjusting the downward force on said arm by adjustable movement along the arm to control the closing of said valve, and consequently the quantity of water discharging through said outlet during each flushing action, wherein said body means includes groove means in a bottom surface thereof receiving said pivotally mounted arm and mounting said body means on the arm, wherein said body means includes slot means extending vertically through the body means and communicating with said groove means for facilitating mounting of said body means on the arm, and including rib means in said groove means for retaining the device on the arm, and wherein said body means defines a rectangular parallelepiped, said groove means being in one surface thereof, and said slot means extending inwardly from one end of said body means into said groove means for facilitating mounting of the body means on said arm.
Claim 2
Dependent Claim
295 words
A flush control device on a valve control in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuation lever and a chain connecting the lever to the valve for opening the latter, the valve control including an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float connected with the arm biasing the valve toward the open position when the tank is full and biasing the valve toward the closed 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 flush control device comprising body means adjustably mounted on said arm between said float and said valve for variably adjusting the downward force on said arm by adjustable movement along the arm to control the closing of said valve, and consequently the quantity of water discharging through said outlet during each flushing action, wherein said body means includes groove means in a bottom surface thereof receiving said pivotally mounted arm and mounting said body means on the arm, wherein said body means includes slot means extending vertically through the body means and communicating with said groove means for facilitating mounting of said body means on the arm, and including rib means in said groove means for retaining the device on the arm, and wherein said body means defines a rectangular parallelepiped, said groove means being in one surface thereof, and said slot means extending inwardly from one end of said body means into said groove means for facilitating mounting of the body means on said arm.
Claim 3
Dependent Claim
291 words
A flush control device on a valve control in a toilet tank having a bottom outlet for discharging water to a toilet bowl, a valve for closing the outlet, a conventional actuation lever and a chain connecting the lever to the valve for opening the latter, the valve control including an arm carrying the valve pivotally mounted in the toilet tank for actuation by the chain to open the bottom outlet, a float connected with the arm biasing the valve toward the open position when the tank is full and biasing the valve toward the closed 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 flush control device comprising body means adjustably mounted on said arm between said float and said valve for variably adjusting the downward force on said arm by adjustable movement along the arm to control the closing of said valve, and consequently the quantity of water discharging through said outlet during each flushing action, wherein said float means lies above said arm and said valve, and said body means is an elongate body member formed with an elongate groove in the lower surface such that said arm lies in said groove, said groove being closed at one end and open at its other end such that said elongate member can be axially inserted between said arm and valve, on the one hand, and said float, on the other hand, with the arm disposed to a greater or lesser extent in said groove, said closed end of said groove defining the maximum degree of insertion when it abuts the pivotal end of said arm.
