Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
In a water closet of the type embodying a water tank with a water supply conduit having a ball-cock-filling valve, a ballcock float positioned in said tank and connected to said ballcock-filling valve and a manually operable discharge drain ball valve, a control tank assembly positioned within said water tank comprising: a. a water-control tank in communication with said water-supply conduit, encompassing a control float and defining an open top, and a discharge drain communicating with said water tank near the bottom of said control tank; b. a float chamber supported above said discharge drain and defining a control-valve seat at its top; c. a buoyant ball-control float and attached control valve, said float supported within said chamber and said valve supported above said seat, so as to float above and open said seat as the water level rises in said water tank and said control tank and so as to rest upon and close said drain, as the water level falls within said water tank and said control tank.
Claim 2
Dependent Claim
170 words
In a water closet of the type embodying a water tank with a water supply conduit having a ball-cock-filling valve, a ballcock float positioned in said tank and connected to said ballcock-filling valve and a manually operable discharge drain ball valve, a control tank assembly positioned within said water tank comprising: a. a water-control tank in communication with said water-supply conduit, encompassing a control float and defining an open top, and a discharge drain communicating with said water tank near the bottom of said control tank; b. a float chamber supported above said discharge drain and defining a control-valve seat at its top; c. a buoyant ball-control float and attached control valve, said float supported within said chamber and said valve supported above said seat, so as to float above and open said seat as the water level rises in said water tank and said control tank and so as to rest upon and close said drain, as the water level falls within said water tank and said control tank.
Claim 3
Dependent Claim
94 words
In a water closet, a control tank as in claim 1, said float chamber having a reduced-diameter top aperture defining said seat and coaxially aligned with said float chamber and said control float and control valve consisting of a control valve positioned above said seat and float member positioned beneath said seat, whereby filling of water in said chamber through said discharge drain raises the control valve above said seat and discharge of water through said control drain causes said valve to fall upon said seat and to hold water in said control tank.
Claim 4
Dependent Claim
11 words
a bottom float of greater dimension than said valve seat; and
Claim 5
Dependent Claim
11 words
a bottom float of greater dimension than said valve seat; and
Claim 6
Dependent Claim
12 words
a relatively thin stem interconnecting said control valve and said control float.
Claim 7
Dependent Claim
12 words
a relatively thin stem interconnecting said control valve and said control float.
Claim 8
Dependent Claim
50 words
In a water closet a control tank as in claim 2, the bottom of said control tank being positioned above the level of said discharge drain in said water tank, so hat water filling into said water tank enters said control tank through the discharge-drain float chamber, and valve seat.
Claim 9
Dependent Claim
41 words
In a water closet, a control tank as in claim 3, said control tank being positioned upon said water supply conduit such that said float reciprocates upon a vertical extension of said water conduit while being linked to said water-supply-filling valve.
Claim 10
Dependent Claim
28 words
In a water closet, a control tank as in claim 3, including an extension tube extending independently from said filling valve to the top of said control tank.
Claim 11
Dependent Claim
