Abstract
A tub waste overflow assembly is provided that is attachable to a tub wall by means of a threaded retaining body insertable through an overflow drain aperture in a tub wall to engage a cooperatively threaded pipe fitting on the opposite side of the tub wall. A chamfered washer is provided to cooperate with the retaining body and an annular sealing gasket to produce a fluid-tight seal on the interior surface of the tub wall and provide frictional engagement with a cover member spanning the drain aperture.
Claims17
A tub overflow waste assembly attachable to a tub wall through an aperture in the tub wall, the assembly comprising:
- a retaining body having a threaded, substantially cylindrical member insertable through the aperture and adapted to be reversibly engageable with a cooperatively threaded pipe fitting aligned with the aperture outwardly of the tub, a flange member disposed adjacent to the cylindrical member interiorly of the tub wall, the flange member having an outside diameter greater than the aperture and an inclined surface facing the tub wall, and a continuous axial bore through the threaded cylindrical member and the flange member;
- an annular polymeric washer having a second bore coaxially aligned with the bore through the threaded cylindrical member, the second bore having a diameter slightly greater than that of the threaded, substantially cylindrical member of the retaining body, the annular washer further comprising an interiorly facing, chamfered surface cooperatively alignable with the inclined surface of the flange member of the retaining body to create abutting contact therebetween upon full insertion of the threaded cylindrical member into the washer bore, the annular washer also having an annular gasket seating surface facing the tub wall around the aperture;
- an interior tub gasket cooperatively alignable with the annular gasket seating surface of the annular washer;
- and
- a cover member having a fluid path that admits overflow waste into the bore of the retaining body.
