Abstract: A drain operating member for a tub or like vessel includes an elongated shaft component having a plunger component on its lower end and a yoke portion on its upper end, the latter being provided with a series of longitudinally spaced apertures. The shaft component is constructed of a material that is relatively rigid and yet resiliently deflectable, to afford positive action to the plunger component while also facilitating installation and accommodating lateral movement produced by the lever. In preferred embodiments, the plunger component will comprise a plug for sealing engagement with an internal seat portion of the conduit assembly with which it is employed, and the shaft and plunger components will advantageously be integrally formed as a single piece. The operating member will preferably have a bifurcated yoke portion, and most desirably will be made from a readily severable material to permit facile alteration of its effective length.

Abstract: A strainer for a tub drain has a spring-biased plunger for moving the stopper from its closed position to an open, liquid flow position. The plunger has a stem that extends into the passageway of the body of the strainer, and is mounted thereon for axial reciprocation between an extended outward (open) position and a depressed inward (closed) position. An axial bore extends through the stopper member, and provides a surface portion conforming to the corresponding portion of the plunger stem. Inward movement of the plunger causes a sealing ring, which is mounted on the stem portion, to be displaced to a position of frictional engagement on the corresponding surface portion of the stopper member bore. Subsequent outward movement, under the force of the biasing spring, causes the plunger to lift the stopper member away from the seat portion of the body, and thereby to open the strainer.
