  • Valved volume dividing means
    Patent number: 4225985
    Abstract: This invention relates to water conserving devices to be used in the water closets of bathroom toilets. The devices may also find applications in other liquid containing and discharging vessels. The invention consists of a partition wall or alternatively a minitank installable in the water closet of a toilet so as to divide the water closet into two separate liquid holding compartments. A flapper valve with a magnetic closure, fitted into the partition wall or into the minitank, opens and closes a port which communicates between the compartments. The actuating means of the flapper valve is operably connected to the existing trip lever of the water closet in such a way that the valve will be actuated only after the existing discharge valve has been actuated first. This arrangement permits the user to discharge water from one or both compartments of the water closet according to his needs.
