Abstract
A basket strainer and stopper assembly for a sink includes a strainer basket, a stopper positioned below the basket strainer for sealing the sink drain opening and an axial stem. The stem has an upper portion which serves as a handle and a lower forked portion which has tines or legs which both support the strainer-stopper assembly in the open drain position and retain it securely in the closed drain position. The legs of the forked portion of the stem are resilient and arcuate and they rest upon a plate extending across the drain opening to support the assembly in the open position. The drain is closed by exerting sufficient downward force on the handle portion of the stem to spring the resilient legs toward each other so they pass through and are retained in a detent opening in the plate. The drain is reopened by pulling upward on the handle with sufficient force to raise the entire assembly and to once again spring the legs toward each other so that they will pass through the detent opening.
