Variable volume flushing cistern

A variable volume flushing cistern comprising:

• a body having a division wall across the cistern body to form a first and second compartment;
• a float located within the cistern body;
• a water inlet valve within the cistern body to be actuated by the float;
• a flushing valve in the said first compartment positioned to discharge from the said first compartment and movable by an operating stem passing through said division wall;
• a movable flap forming part of the said division wall to allow the said second compartment to be isolated from the said flushing valve in the said first compartment;
• first operating means connected to the said operating stem to actuate the said flushing valve to initiate a large flush from both said compartments;
• and
• second operating means connected to said operating stem to actuate the flushing valve and said flap to close the said flap to isolate the said second compartment from the said flushing valve, thus initiating a smaller flush from said first compartment, said division wall having a portion extending over the flushing valve and on one side extending upwardly and on the other side having a portion adapted to be engaged by said flap, the said flap being hinged to the floor of the said body to define with the division wall the said first and the second compartments, said first operating means comprising a first rotatable member, said first member being operated by a button connected thereto, a second rotatable member positioned adjacent to said first member, said second member being coupled to the said operating stem by connecting means and said first member being adapted to engage with said second member whereby operation of the button causes the first member to rotate and engage the second member causing the second member to rotate to activate the operating stem to operate the said flushing valve, and said second operating means comprising a third rotatable member located adjacent the second member and remote from said first member, said third member being operated by a second button connected thereto and having a member projecting therefrom and adapted to engage a projection extending from said flap in the direction of said first compartment, said third member being adapted to engage said second member whereby operation of the said second button causes the third member to rotate and engage the second member causing the second member to rotate and activate the operating stem to operate said flushing valve, while simultaneously the said member projecting from the third member bears on the flap projection and closes said flap to isolate the said second compartment from the flushing valve to initiate a smaller flush from the said first compartment.
