Abstract
Abstract A toilet flushing arrangement selectively operable to discharge different amounts of water from the toilet tank into the toilet bowl depending on the quantity and nature of the waste material to be flushed from the bowl. For this purpose a water level control tube is mounted over the discharge port of the tank, and provided within the walls of said tube at different levels vertically thereof are circlets of openings. Sleeves slidably received within the tube are arranged to block the flow of water from the tank through the openings into the center region of the tube when they are in their position of rest. Exteriorly of the tank dual actuating means are operatively connected to the sleeves in the level control tube and may selectively be manipulated to lift one or the other of the sleeves individually. When a sleeve has been lifted, water from the tank will flow freely through the unblocked openings into the interior of the level control tube and from there into the toilet bowl until the water in the tank has dropped to the level determined by the unblocked openings.

Claim 1
Independent Claim
141 words
A dual flushing arrangement for water toilets comprising a water tank having a bottom and provided in said bottom a discharge port, a tube mounted over said discharge port and having openings provided in its wall at different levels vertically thereof for the admission of water from the tank into the interior of the tube and hence through said discharge port into the toilet bowl, plural opening-blocking means selectively movable from a first position wherein they block the flow of water through the openings at said different levels into a second position wherein they unblock said openings, said openingblocking means having central openings to establish communication between said water tank and said discharge port, and means exteriorly of said tank selectively operable to selectively move one or the other of said opening-blocking means individually from said first to said second position.
