Abstract
Abstract A replacement valve for the holding tank of a toilet which includes a conical elastic valve element attached to a buoyant disc on the upper surface thereof. This valve assembly is then mounted on a centrally received shaft which extends downwardly from the lower surface of the valve to be received in the interior of a coiled spring centering guide. The centering guide, at the lower end thereof, includes four flexible convolved wire fingers which are compressed for receipt within the valve seat assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
32 words
A replacement valve assembly adapted for insertion into the seat of a flush outlet of a toilet holding tank, comprising: a frusto-conical flexible valve seal conformed for receipt in said valve seat;
Claim 2
Dependent Claim
32 words
A replacement valve assembly adapted for insertion into the seat of a flush outlet of a toilet holding tank, comprising: a frusto-conical flexible valve seal conformed for receipt in said valve seat;
Claim 3
Dependent Claim
96 words
a buoyant disc attached to the upper surface of said valve seat; a centering shaft concentrically attached to said disc and said seal to extend axially therefrom in a direction away from the lower surface of said seal; and a centering yoke assembly supporting in contilener a coiled spring guide adaped to telescopically receive said centering shaft, a plurality of flexible fingers extending from the lower end of said guide, the free ends of said fingers extending beyond the dimensions of said outlet whereby an insertion of said fingers into said outlet maintains fingers in position.
Claim 4
Dependent Claim
96 words
a buoyant disc attached to the upper surface of said valve seat; a centering shaft concentrically attached to said disc and said seal to extend axially therefrom in a direction away from the lower surface of said seal; and a centering yoke assembly supporting in contilener a coiled spring guide adaped to telescopically receive said centering shaft, a plurality of flexible fingers extending from the lower end of said guide, the free ends of said fingers extending beyond the dimensions of said outlet whereby an insertion of said fingers into said outlet maintains fingers in position.
Claim 5
Dependent Claim
40 words
Apparatus according to claim 1 wherein: said centering shaft is dimensioned to a length substantially greater than said guide and includes an enlarged cap formed on the free end thereof having dimensions greater than the interior dimensions of said guide.
Claim 6
Dependent Claim
20 words
Apparatus according to claim 2 further comprising: an articulable lever connected to said seal means for providing vertical articulation thereof.
Claim 7
Dependent Claim
79 words
A centering guide adapted for insertion into a valve seat for aligning the centering shaft of a valve during articulation, comprising: a plurality of flexible wire elements coiled to form an interleaved helical coil over the first sections thereof and extending along radial planes from said guide in the form of bent over fingers over the second sections thereof, the free ends of said fingers being separated by a dimension greater than the interior dimension of said valve seat.
Claim 8
Dependent Claim
79 words
A centering guide adapted for insertion into a valve seat for aligning the centering shaft of a valve during articulation, comprising: a plurality of flexible wire elements coiled to form an interleaved helical coil over the first sections thereof and extending along radial planes from said guide in the form of bent over fingers over the second sections thereof, the free ends of said fingers being separated by a dimension greater than the interior dimension of said valve seat.
Claim 9
Dependent Claim
21 words
Apparatus according to claim 4 wherein: said wire elements are bonded together at the juncture of said fingers and said guide.
Claim 10
Dependent Claim
28 words
Apparatus according to claim 5 wherein: said seat includes a downwardly directed tapered surface; and said valve includes a frusto-conical elastic segment adapted to mate with said seat.
Claim 11
Dependent Claim
20 words
Apparatus according to claim 6 wherein: said centering shaft is disposed axially from said valve for receipt in said guide.
