ABSTRACT:
A bath drain outlet control having an actuator, a plunger valve for engaging a valve seat of a bath drain outlet, a linkage between the actuator and the plunger valve, including a one-way slip clutch enabling the linkage to be contractably adjustable, and a slip clutch deactuator movable into operative relationship with the one-way slip clutch to temporarily allow expansion adjustment of said linkage. The one-way slip clutch has an elongated rod forming part of the linkage, a retaining ring having a plurality of sloped spring fingers around the rod, having an inherent bias toward the rod, and having rod engaging ends normally allowing rod movement in a linkage-contracting direction therethrough but preventing reverse rod movement therethrough in a linkage-extending direction. A compressed O-ring engages the sloped spring fingers to add bias supplementing the inherent finger bias toward said rod and equalizing the bias of the spring fingers against the rod.
