Abstract
Abstract A TOILET ASSEMBLY INVOLVES A FLUSHING BOWL AND A SEPARATOR FLAP PIVOTALLY MOUNTED AND SPRING-URGED NEAR THE LOWER END OF SUCH BOWL TO NORMALLY BLOCK THE VIEW INTO A LOWER, BOTTOM TANK. THE FLAP IS DISPLACEABLE BY FLUSHING LIQUID TO AN OPEN POSITION DURING NORMAL FLUSHING OPERATIONS AND THE SPRING THEN RETURNS THE FLAP AUTOMATICALLY TO CLOSED POSITION. FOR CLEANING AND OTHER PURPOSES THE FLAP MAY BE MOVED TO AN EXTREME OPEN POSITION, WHEREIN IT IS AUTOMATICALLY MAINTAINED IN A LATCHED CONDITION BY A SPECIALLY CONSTRUCTED SPRING WHICH, IN ADDITION, PERFORMS THE OTHER FUNCTIONS MENTIONED ABOVE.
