Abstract
An improved plug device for the drain of a basin or a bathtub, which is comprised of a roller mounted on a rod and spring enclosed by two semicircular sleeves, which when assembled together form a cylindrical sleeve. The roller is guided by a guide groove which is carried on the inner wall of the two semicircular sleeves. The roller is connected to a drain plug by a rod and spring urges the device upwardly. The guide groove has rest positions so that by simply depressing the plug sequentially, the plug is automatically set in either the open or closed position.
