Abstract
Abstract Watersaving flush valve controls for toilets having two different capacity discharges from a reservoir. Said control having one opening and valve for lesser capacity outlet when lesser quantity discharge is required and another for using a greater capacity outlet when full discharge is required. Each control is selective and will terminate discharge action after selected discharge.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
145 words
In a water system for delivering a flow of water in a selective volume to a conduit outlet, communicating with a conventional flush toilet bowl, a first conduit for conducting a flow of water between a source of supply and an outlet from said first conduit, a branch line extending from an upstream portion of said first conduit and returning to a downstream portion of said first conduit, a valve controlling flow positioned in said first conduit between the point of departure of said branch line upstream of said valve and the point of return of said branch line to a juncture with said first conduit downstream of said valve, a valve controlling flow in said branch line between said point of departure and said juncture, and a vacuum breaker in said first conduit downstream of the branch juncture and upstream of the conduit outlet.

Claim 3
Dependent Claim
69 words
The combination with a toilet bowl, of two conduits supplying flush water to said bowl, one said conduit supplying a lesser flow, and the other said conduit supplying a greater flow, and a separate manually operable valve in each conduit for establishing the flushing flow therethrough, whereby a person operating said valves may selectively determine the volume of a given flush by actuation of either of said valves separately.
