Abstract: A hydrostatic drain plug/outlet assembly comprises a hollow body (1) with an inlet port and an outlet port for connection to a fluid conduit. A slidable valve member (6) is movable between a locked open position and a locked closed position via an intermediate position at which the valve member (6) is urged into sealing engagement with a sealing member (3) by a spring (21) which supports a hydrostatic pressure of predetermined magnitude beyond which excess hydrostatic pressure is relieved by the valve member to prevent fluid overflow in a vessel. The valve member is moved between the locked open position and the locked closed position by rotation of valve member (6).

A closure member with a central bore is rotatably mounted on the post and is rotatable with the post when lifted to a position within the annular groove. A washer is secured within the center bore of the closure member and has a circular center bore with a flat segment adjacent thereto to permit the closure member to dwell within the annular groove when the flat segment is out of alignment with the planar surface of the post, but which will permit the closure member to slidably turn relative to the post when the flat surface is in alignment with the planar surface.

Abstract: A drain assembly which improves on the durability, economy and ease of manufacture and maintenance of previous drain assemblies. The drain assembly has a cartridge that threads onto a drain body. A spud or stopper slides up and down along the cartridge to open or close a drain. The improvement lies in a series of flexible structures extending outwardly from the cartridge to generate friction against the inner wall of the spud, holding the spud in the open of closed position. These structures may be finlike structures, bowlike structures, or both. The cartridge with the finlike structures and bowlike structures may be formed of a single piece of flexible plastic.

Abstract: A magnetically activated drain plug apparatus employs a permanent magnet placed externally of a plastic or thin non-magnetic drain pipe while another permanent magnet is placed at the lower end of the drain plug. The external magnet can be a ring shaped magnet, a plurality of magnets in a ring held in a support arm or a magnet slideably retained in a rail on the outside of the pipe. The external magnet is operated by a lever linkage or flexible cable that is external to the drain pipe. Moving the external magnet by operating the linkage or the cable attracts or repels the magnet in the drain plug. Consequently, due to the magnetic attraction or repulsion, the drain plug is moved between an open and a closed position. Guide nubs on the interior of the drain pipe and a stem or fins on the drain plug can be interengaged, thereby preventing tilting or rotation of the drain plug while in the up or open position.

Abstract: A movable fitting member such as a bathtub drain stopper can be constructed so as to be useful with different drain fittings which differ by having post holders with different sized openings into which a guide post can be threaded. Such a movable fitting member is constructed so as to use a body having a sleeve located around a post holder and having an enlarged cavity around the post holder within the body. The guide post used is double ended; one end is threaded into the post holder in a drain fitting and the other end is located within the cavity. A nut is located on this other end; it is sufficiently large so that it cannot pass through the sleeve. As a result of this the body cannot normally be separated from the guide post during the use of the fitting member.

Abstract: The present invention is a sewage clean-out line cover and removable cap made of Ultra High Molecular Weight Polyethylene. The interior of the cover carries a plurality of rows of upwardly inclined teeth, the rows being parallel and unconnectable to each other. The teeth comprising each row have a pitch to depth ratio of approximately 1:1. The ratio of the slope of the upper surface of the teeth to the lower surface is 1:1, thus providing a tip for installation over the open end of the upstanding clean-out pipe which tip is flexible for pushing the cover over the open end of the clean-out pipe due to the inherent lubricity of the UHMWPE but which resists removal of the cover by the tips folding over to increase friction against the clean-out pipe outer surface. The cover is usable with cast iron or PVC pipe or any other presently known material used to form sewage clean out pipes.
