Abstract

See full text

Disclosed is a discharge drain assembly (for use in a sink) including a drain body and a plug assembly adapted to fit in the drain body which features limited rotational movement between an open and a closed position. The plug includes a stainless steel strainer with an integral hollow knob having opposed sides which are inwardly concave. The knob securely but releasably retains a slotted head portion of a spindle. The spindle has a neck portion for receiving a sealing washer and a lower body portion including three leg portions. The leg portions support the plug in the open position, restrain rotation in a first direction beyond the open position, and cam the plug to the closed position when rotated in a direction opposite said first direction. The structure substantially eliminates a 'finding' problem common in prior art arrangements and provides a good seal in the closed position.
