1 Claim. (ore-57) The present invention relates to a resilient repair seat of rubberlike material for use in a flush tank valve.
A purpose of the invention is to permit the cheap and easy restoration of service in a flush tank valve seat which has become worn and pitted without the expense of the replacement of the metallic seat.
A further purpose is to enable a householder to restore service in a flush tank which has failed to function through damage to the valve seat without calling upon the services of a plumber.
Further purposes appear in the specification and in the claim.
In the drawings I have chosen to illustrate one only of the numerous embodiments in which my invention may appear, choosing the form shown from the standpoints of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.
Figure 1 is a fragmentary diagrammatic perspective view of a flush tank valve and seat to which the invention has been applied.
Figure 2 is a top plan view of the seat of Figure 1.
Figure 3 is an axial section of Figure 2, on the line 3--3.
Figure 4 is a section of Figure 3 on the line 4-4. I
Figure 5 is a perspective of the repair seat of the present invention.
In the drawings like numerals refer to like parts.
Describing in illustration but not in limitation and referring to the drawings:
After extended use the metallic seat in a flush tank frequently becomes sufliciently corroded or worn so that the ball valve does not seat tightly. This has frequently necessitated replacement of the seat along with the overflow pipe which constitute a single unit. Such replacement normally requires the services of a plumber.
The present invention is concerned particularly with the temporary or permanent repair of the seat so that it can continue service when corroded or worn without replacement.
As shown in the drawings, the flush tank valve assembly consists of a ball valve 20, usually of rubber supported on a stem 21 suitably guided by means not shown, in parallel relation to an overflow pipe 22.
The overflow pipe is mounted on an extension 23 from the side of a valve seat 24 which is integral with a nipple 25 for threaded connection 2 pipe with the interior 21 of the nipple to permit drainage.
The seat 24 flares outwardly and the surfaces which are likely to become corroded and worn are the interior surfaces 28 which cooperate with the valve 20.
The repair seat 30 of the present invention is conveniently made of an elastomer such as rubber or synthetic rubber sufliciently soft to be flexible and normally of durometer reading in the range between 30 and 80. The repair seat comprises an elongated cylindrical portion 33 having one or preferably several radial ports 34 which permit overflow from the pipe 26 to enter the interior of the nipple, an outwardly flaring seat portion 32 which engages the ball valve conforming as nearly as possible on the outside and inside to the contour of the metallic seat, the outwardly flaring'portion 32 merging with the cylindrical portion 33, and a flat annular rim 3! in which the outwardly flaring portion terminates.
At the lower end the skirt is provided with an outwardly extending flange 35 which has a diameter greater than the interior diameter of the nipple. Therefore when the repair seat is forced into place the flange 35 and the skirt are contracted and grip the interior of the metallic nipple. The skirt itself when contracted will clear from the nipple as shown at 36.
In operation it will be seen that it is merely necessary to lift the ball valve and reach down with the hand under the ball valve inserting the elastomer repair seat in the metallic valve seat, and then forcing it down against the resistance due to the contraction of the flange 35 and the skirt.
The holes 34 are amply larger than the passage 26 and there is suflicient freedom in the space 38 so that it normally is not necessary to align the holes carefully with the passage 26.
In view of my invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the structure shown, and I, therefore, claim all such insofar asthey fall Within the reasonable spirit and scope of my claim.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
A flush tank valve seat repair fitting adapted to cooperate with a flush tank valve seat havin a flaring seat portion and. a depending nipple portion and having an overflow pipe connected at one side beneath the flaring seat portion, said repair fitting being of rubber-like material comprising a lower radially apertured cylindrical wall, the aperture being adapted to provide drainage from an overflow pipe adjacent to the valve seat with which the repair fitting is intended to be used, an external gripping flange at one end of the cylindrical wall having an external diameter substantially larger than the internal diameter of the nipple portion of the said valve seat and larger than the external diameter of the cylindrical wall and therefore adapted to grip the inner wall of said nipple portion resiliently, an outwardly flaring valve seat portion merging with the cylindrical wall at the other end from REFERENCES CITED The following references are of record in the file of this patent:
