Abstract
Abstract A trapway reseal device for a toilet tank where the toilet tank includes an overflow tube and a water control. The trapway reseal device includes a float slidably supported along the overflow tube to move with the changing level of water in the tank as the tank is flushed and refilled. A reseal hose receives water from the water control and includes a free end coupled to the float. The reseal hose selectively directs water into at least one of the tank in the overflow tube dependent upon the position of the float as determined by the level of water in the tank.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
A trapway reseal device for a toilet tank, said toilet tank including an overflow tube having a retaining pin across a top thereof and a splash guard on a side of the top of said tube, and a water control, comprising an annular float adapted to be slidably supported around said overflow tube to move with the changing level of water in said tank as said tank is flushed and refilled, said float movable upward to a point on said tube whereat said retaining pin is positioned, and a reseal hose receiving water from said water control and having a free end directly coupled to said float, said reseal hose selectively directing water into at least one of said tank and said overflow tube dependent upon the position of said float as determined by the level of water in said tank, said annular float being in the shape of a doughnut having an opening therethrough, said overflow tube extending through said opening.
Claim 2
Dependent Claim
162 words
A trapway reseal device for a toilet tank, said toilet tank including an overflow tube having a retaining pin across a top thereof and a splash guard on a side of the top of said tube, and a water control, comprising an annular float adapted to be slidably supported around said overflow tube to move with the changing level of water in said tank as said tank is flushed and refilled, said float movable upward to a point on said tube whereat said retaining pin is positioned, and a reseal hose receiving water from said water control and having a free end directly coupled to said float, said reseal hose selectively directing water into at least one of said tank and said overflow tube dependent upon the position of said float as determined by the level of water in said tank, said annular float being in the shape of a doughnut having an opening therethrough, said overflow tube extending through said opening.
Claim 3
Dependent Claim
35 words
The trapway reseal device as claimed in claim 1, wherein said float drops on said overflow tube after said toilet tank is flushed to a level where said reseal hose directs water into said tank.
Claim 4
Dependent Claim
40 words
The trapway reseal device as claimed in claim 2, wherein said float rises on said overflow tube as said toilet tank refills after flushing, said reseal hose directing water into said overflow tube when said float reaches a predetermined height.
Claim 5
Dependent Claim
15 words
The trapway reseal device as claimed in claim 3, wherein said predetermined height is adjustable.
Claim 6
Dependent Claim
23 words
The trapway reseal device as claimed in claim 1 wherein said reseal hose is coupled to said float by means of a clip.
Claim 7
Dependent Claim
160 words
A trapway reseal device for a toilet tank having an overflow tube having a retaining pin across a top thereof and a splash guard on a side of the top of said tube, and a reseal hose which receives water from a water control in said tank, comprising a float supported around said overflow tube which floats in the water in said tank and which rises and falls on said overflow tube with the changing level of water in said tank as said tank is flushed and refilled, said float movable upward to a point on said tube whereat said retaining pin is positioned, and coupling means for coupling said reseal hose directly to said float, said reseal hose selectively directing water into said overflow tube only when said float reaches at least a predetermined height in said tank, said annular float being in the shape of a doughnut having an opening therethrough, said overflow tube extending through said opening.
Claim 8
Dependent Claim
160 words
A trapway reseal device for a toilet tank having an overflow tube having a retaining pin across a top thereof and a splash guard on a side of the top of said tube, and a reseal hose which receives water from a water control in said tank, comprising a float supported around said overflow tube which floats in the water in said tank and which rises and falls on said overflow tube with the changing level of water in said tank as said tank is flushed and refilled, said float movable upward to a point on said tube whereat said retaining pin is positioned, and coupling means for coupling said reseal hose directly to said float, said reseal hose selectively directing water into said overflow tube only when said float reaches at least a predetermined height in said tank, said annular float being in the shape of a doughnut having an opening therethrough, said overflow tube extending through said opening.
Claim 9
Dependent Claim
31 words
The trapway reseal device as claimed in claim 6, wherein when said float reaches said predetermined height, said reseal hose directs water into overflow tube for a predetermined period of time.
Claim 10
Dependent Claim
17 words
