Self adjust tub drain stop

A bath drain outlet control comprising:

• an actuator, said actuator having a link;
• a plunger valve for engaging a valve seat of the bath drain outlet;
• a linkage between said actuator link and said plunger valve, said linkage having a one-way slip clutch enabling said linkage to be contractibly adjustable;
• said one-way slip clutch comprising an elongated rod forming part of said linkage, a retaining ring having a plurality of sloped spring fingers around said rod having inside surfaces toward said rod and outside surfaces away from said rod, and having an inherent bias toward said rod, said spring fingers 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;
• and
• an O-ring and a retention surface holding said O-ring in firm engagement with said outside surfaces of said plurality of sloped spring fingers in a manner to add bias to said sloped spring fingers, supplementing said inherent fingers bias toward said rod and balancing the bias load on said spring fingers.
