ABSTRACT:
A rocker beam construction for use with plumbing fixtures, for insertion within a drain tube to transmit stopper opening motion from a drain actuating linkage acting at one end of the drain tube, to the stopper located at the other end of the drain tube, comprises a unitary beam having a relatively thin deep substantially flat subsection transversely flexible relative to the plane of the web, which may be inserted within the drain tube by turning the beam on its side and bending it down through the drain aperture and into the drain tube, where it is repositioned having the web thereof in a vertical plane for engagement by the actuating linkage in a downward depressing motion, the improved device having a post portion connecting one end of the rocker beam with the stopper, to transfer rocking downward displacement of the beam by the actuating linkage into upward rocking displacement of the stopper means. The post-to-stopper construction permits the use of an interposed locking collar to preclude to preclude unauthorized removal of the beam and stopper assembly.
