Abstract
Abstract This invention provides a flush regulator for use in a toilet flush tank, in order to regulate the outflow through the outlet pipe in such a way that less water is used per flush than normally is the case. The regulator includes a gripping means for attaching to the vertical stem which is screwed into the standard ball valve, and the gripping means supports two upright post members from which upwardly open cups are supported. The cup members are wholly to one side of their respective post members, and are positioned such that rotation of the regulator with respect to the bracket normally supporting the stem will bring one of the post members into contact with the bracket, rather than a cup member. By insuring that the cup members do not contact the bracket, interference with the intended vertical motion of the regulator, ball valve and stem is avoided.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
A flush regulator for use in a toilet flush tank for regulating the outflow therefrom through an outlet pipe, the toilet flush tank including a hollow ball valve adapted to stop up the outlet pipe, a vertical stem with its lower end attached to the ball valve and its upper end adapted to be pulled up to initiate a flush, and a bracket extending laterally from an overflow pipe within the tank and having a vertical bore through which the stem passes, the regulator comprising: gripping means for gripping the vertical stem, two upright post members supported from said gripping means, the post members being spaced from the stem and from each other, and two upwardly open cup members capable of containing water mounted respectively to the post members, each cup member being wholly to one side of its respective post member and positioned such that rotation of the regulator in one direction with respect to the bracket will bring one of the post members into contact with the bracket, and rotation of the regulator in the other direction with respect to the bracket will bring the other post members into contact with the bracket, thereby preventing contact or catching of a cup member under or against the bracket.
Claim 2
Dependent Claim
209 words
A flush regulator for use in a toilet flush tank for regulating the outflow therefrom through an outlet pipe, the toilet flush tank including a hollow ball valve adapted to stop up the outlet pipe, a vertical stem with its lower end attached to the ball valve and its upper end adapted to be pulled up to initiate a flush, and a bracket extending laterally from an overflow pipe within the tank and having a vertical bore through which the stem passes, the regulator comprising: gripping means for gripping the vertical stem, two upright post members supported from said gripping means, the post members being spaced from the stem and from each other, and two upwardly open cup members capable of containing water mounted respectively to the post members, each cup member being wholly to one side of its respective post member and positioned such that rotation of the regulator in one direction with respect to the bracket will bring one of the post members into contact with the bracket, and rotation of the regulator in the other direction with respect to the bracket will bring the other post members into contact with the bracket, thereby preventing contact or catching of a cup member under or against the bracket.
Claim 3
Dependent Claim
37 words
The invention claimed in claim 1, in which the positions of the cup members are such that the regulator has its center of gravity close to the vertical stem, when the cup members are full of water.
Claim 4
Dependent Claim
39 words
The invention claimed in claim 1, in which each post member includes a portion adapted to contact the bracket upon rotation of the regulator, the respective cup member being mounted to the post member remote from said last-mentioned portion.
Claim 5
Dependent Claim
55 words
The invention claimed in claim 1, in which the post members are T-shaped in horizontal section, the stem of the "T" being adapted to contact the bracket upon rotation of the regulator, the respective cup member being mounted to the cross-member of the "T" and being adjustable in height with respect to the post member.
Claim 6
Dependent Claim
32 words
The invention claimed in claim 4, in which each post member has a plurality of spaced-apart protrusions so as to establish a plurality of specific vertical locations for the respective cup member.
Claim 7
Dependent Claim
35 words
The invention claimed in claim 1, in which the gripping means is in the form of a pincer grip which can be applied to the stem from the side without disassembly of the ball valve.
Claim 8
Dependent Claim
32 words
The invention claimed in claim 1, which further includes sleeve means for insertion into said vertical bore, the sleeve means providing a center passage which can snugly but slidably receive said stem.
Claim 9
Dependent Claim
96 words
The invention claimed in claim 6, in which the pincer grip has two interlocking jaw members extending in a first general direction away from a pincer location adapted to receive the stem, each of the post members extending from the end of a support arm which is integral with the gripping means, the support arms being disposed in such a way that, with both cup members supported from their respective post members in the same side and filled with water, the center of gravity of the regulator falls close to the position of the vertical stem.
Claim 10
Dependent Claim
32 words
The invention claimed in claim 1, in which each post member has a plurality of spaced-apart protrusions so as to establish a plurality of specific vertical locations for the respective cup member.
