Abstract
Abstract Disclosed herein is a water saving toilet characterized in that a single handle actuates either of two water sealing valves horizontally offset one from the other and when actuated makes it possible to vary the amount of water introduced into the bowl so that a lesser amount of water can be used to evacuate urine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
A water saving mechanism for a toilet reservoir comprising a water evacuation column connected to a commode, a pair of conduit means communicating with said column and horizontally offset one from the other, valve ball means removeably nested within said conduit means, and linkage means connected to said valve ball means for selectively removing one of the two valve balls so as to provide different volumes of water into the commode bowl by virtue of the different vertical heights of said conduits in which said linkage means includes an upper and lower chain, the upper chain being connected to the upper valve ball, the lower chain being connected to the lower valve ball, and a single lever connected at opposed extremities to the terminal point of each of said chains whereby rotation of said lever in a clockwise direction will actuate one valve ball and rotation of the said lever in the opposite direction will actuate said other valve ball and in which said chains are connected to said lever through ears and in which said lever is spring biased at the opposed extremities so as to return said lever to an initialized state.
Claim 2
Dependent Claim
194 words
A water saving mechanism for a toilet reservoir comprising a water evacuation column connected to a commode, a pair of conduit means communicating with said column and horizontally offset one from the other, valve ball means removeably nested within said conduit means, and linkage means connected to said valve ball means for selectively removing one of the two valve balls so as to provide different volumes of water into the commode bowl by virtue of the different vertical heights of said conduits in which said linkage means includes an upper and lower chain, the upper chain being connected to the upper valve ball, the lower chain being connected to the lower valve ball, and a single lever connected at opposed extremities to the terminal point of each of said chains whereby rotation of said lever in a clockwise direction will actuate one valve ball and rotation of the said lever in the opposite direction will actuate said other valve ball and in which said chains are connected to said lever through ears and in which said lever is spring biased at the opposed extremities so as to return said lever to an initialized state.
Claim 3
Dependent Claim
33 words
The device of claim 1 in which said conduit means are provided with a taper so as to accelerate the water flow when the flow goes through said conduit and into said column.
Claim 4
Dependent Claim
31 words
The device of claim 2 in which said conduits are provided with an upper portion proximate to said water evacuation column having a taper of approximately 45% relative to the horizontal.
Claim 5
Dependent Claim
36 words
The device of claim 1 in which said valve balls are each pivotally connected to said water evacuation column by rod means so as to cause said valve balls to rotate and return to said conduits.
Claim 6
Dependent Claim
27 words
The device of claim 1 in which said conduit means are provided with a rim portion which can nest with the sealing portion of said valve ball.
Claim 7
Dependent Claim
47 words
The device of claim 1 in which said lever is supported on a shaft which extends through the water reservoir and terminates in an handle orthogonally offset from said shaft and sealing means are provided on said shaft at said reservoir to discourage water flow outwardly therefrom.
