Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
In combination with a toilet bowl having a siphon forming outlet comprising, a bowl, said bowl having a sump for containing a quantity of water, a downwardly directed outlet for said bowl communicating with said bowl to receive fluids from said bowl during flushing thereof, a flexible open-ended tubular member in said outlet supported at its upper end and hanging downwardly therein and forming a flow path therethrough for said fluids whereby fluids flowing through said flexible tube cause the lower end of said tube to restrict the opening therethrough a jet nozzle adapted to be connected to the main water line under pressure said jet being supported above said flexible tube to direct water therethrough said flexible tube being adapted to be collapsed together by a differential in pressure between the pressure inside said tube and the pressure outside said tube thereby increasing the rate of flow of fluids by venturi action.
Claim 2
Dependent Claim
153 words

Claim 3
Dependent Claim
16 words
The combination recited in claim 1 wherein said bowl has rinsing nozzles disposed around said rim.
Claim 4
Dependent Claim
38 words
The combination recited in claim 2 wherein said flushing water supply means is supported in said closet for directing flush water downwardly into said outlet through said tubular member thereby increasing the flow rate through said tubular member.
Claim 5
Dependent Claim
47 words
The combination recited in claim 1 wherein a valve is connected in series with said supply of water and a pressure-sensitive means is connected to said sump and to said valve for turning off said valve when the pressure of said sump drops below a predetermined amount.
