  • Patent number: 5428847
    Abstract: A drain assembly includes a drain body, a sleeve, a shaft and a plug. The drain body has an axial bore and a transverse cruciform web mounted in the bottom of the bore. The sleeve has an axial bore that is substantially coaxial to the drain body bore. The exterior surface of the sleeve bottom end portion is threaded for engagement with a threaded aperture in the drain body web. The shaft is slidably disposed within the sleeve bore and is retained in the sleeve by a clip. The plug has a threaded axial blind bore for engagement with the threaded outer surface of the shaft top portion and a frustum-like circumferential surface that engages the drain body seating surface to seal the drain body bore. An integral handle longitudinally extending from the top of the plug provides a means for grasping the plug to axially displace the plug to open or close the assembly.
