ABSTRACT:
In a kitchen sink, it is known to have a drain plug at the bottom of the sink; it is unpleasant to remove this plug when the sink is full of liquid. In this invention, a sliding valve controls the flow of liquid from the sink within the sink drain tube. An apertured sliding plate is housed within a two-part bored casing connected to the sink drain tube. Pushing the sliding plate toward the sink drain tube closes the latter and vice-versa. A pivotable handle surmounting the sink activates the sliding plate through a multi-lever connecting link. The two casing parts are fitted with a gasket in between and are detachable. Each part is welded to a drain nipple. The two drain nipples are series connected in the drain line. The entire assembly is easily installed and removed.
