Abstract: A tub waste overflow assembly 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. The retaining body is provided with an annular flange larger than the aperture, a plurality of lugs circumferentially spaced around the tubular bore and extending forwardly of the flange, opposite the male threaded end, and a selectively removable test plug molded in place across the tubular bore at the flange end.

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.

Abstract: A steam generator having an elongated vessel provided with opposed upper and lower ends and having in its interior adjacent its upper end a single transversely extending tube plate and a partition extending upwardly from said tube plate and dividing the interior space of the vessel above the tube plate into a heating-medium receiving chamber and a heating-medium discharge chamber. A bundle of tubes are connected with and extend downwardly from the tube plate to the region of the lower end of the vessel, each of these tubes having an inlet end communicating with the receiving chamber and an outlet end communicating with the discharge chamber and each of these tubes having a substantially U-shaped configuration at the region of the lower end of the vessel.
