Abstract: A drain valve comprises:(a) a drain body defining a flow port,(b) a drain cover unit movable between a down-position in which the cover closes the port, and an up-position to open the port to drain flow, the cover having a downward projection movable up and down in the port, the projection containing an upwardly extending recess, which opens downwardly,(c) a latching post carried by the drain body and extending upwardly in the recess, so as not to be movable up and down with the cover,(d) a spring anchored to the cover unit to extend downwardly into cooperative relation with the post characterized in that the post and spring yieldably hold the cover unit in centered relation to the body, and the spring also yieldably resists movement of the cover unit to down position,(e) and structure for releasably latching the projection to the post in response to movement of the cover unit to down position, and to unlatch the cover unit in response to tilting of the cover unit in down position.

Abstract: A drain assembly has a downwardly projecting threaded stem, and in combination with the assembly there are:(a) a tube having an upwardly opening bore below the stem,(b) an annular part having a skirt adjustably fitting said bore to be bonded thereto at selected elevation and penetration into the bore, and(c) a nut relatively rotatably interfitting said part and retained thereto, said part having an annular portion projecting upwardly and telescopically relative to the nut,(d) the nut telescopically interfitting the stem and having threaded connection therewith, whereby upward tightening of the nut on the stem operates to energize a seal between said part annular portion and said stem, and said nut is disconnectible from the stem to enable cleaning of the interior of the nut, part and tube.

Abstract: A drain assembly, for a drain floor having an opening toward which a drain pipe projects, comprises:(a) a tubular plastic body sized to exteriorly fit the drain floor opening, the body having an external thread, and a nut threadably engaging the body thread and rotatable relative to the body, the nut defining an exterior flange, the body and nut consisting of molded plastic material,(b) a plate defining an upper flange overlapping the top of the body, and a grille bounded by the upper flange and overlapping the upper interior of the body,(c) and a tubular base having a flange attached to the nut flange at the underside thereof, the base having a tubular portion projecting downwardly for reception of the upper extent of said pipe, said base consisting of molded plastic material.
