Abstract: A drain removal tool with a central opening aligned along a central tool axis, a holding section with a hex head for applying torque to the tool, and an engagement section including elongate sharp ridges or teeth extending in a helical pattern from an external surface of the engagement section from the tool for engagement with the drain to be removed. Each elongate sharp ridge has one flat face and a ramp face. Each flat face is aligned along a radius extending outwardly from the central tool axis. The ridges are spaced such that the distance between each flat face is approximately 6 degrees. Each helical ridge is a left hand helical serration on a 15 degree pitch with respect to the central axis of the central opening. The holding section includes a hex head configuration. The central opening in the holding section has a hex configuration.

Abstract: A pipe wrench or tool with an improved I-beam handle design having a ramped or tapered cross-sectional configuration, as well as an optional stronger ductile iron material. Specifically, the portion of the tool handle adjacent the jaw or tool operating portion, has wider flanges in the I-beam configuration than the flanges in the opposite end of the tool handle. Such a design adds additional strength at what are typically critical stress areas of the tool handle. The use of the present handle design, along with the use of a stronger ductile iron material, as disclosed here, provides wrenches using these features with a substantial improvement in tool strength as compared to conventional tools.

Abstract: A powered hand held drain cleaning tool and method of operation, including a stick tool member with a brush or teeth on a first end, a hex engagement portion on a second end and an elongate, non-uniform, shaft portion extending between the first and second ends. The tool includes a body portion for housing a power supply, a motor for rotating a drive mechanism engaged with the hex engagement portion of the stick tool member, and a trigger switch mechanism for operation of the tool by a user. The body is also engaged with a face piece with an opening for receiving the stick tool member therethrough, and pin members for mating and locking engagement with locking grooves formed in the body portion.

Abstract: A drain spud wrench having a wrench body, a first end portion and a second end portion. The first end portion extends from the wrench body in alignment with a longitudinal axis of the wrench body. The first end portion includes structure that is configured to engage a drain spud. The second end portion extends from the wrench body in a direction opposite from the first end portion. The second end portion defines a polygonal recess configured to accept a standard socket drive. In one embodiment, the polygonal recess is sized and shaped to accept toilet seat nuts.

Abstract: An under-sink waste pipe system comprises first and second waste pipes telescoped together, a softly resilient seal ring that adapts a smaller pipe for coupling to a larger pipe, seals the waste-pipe juncture, and secures the waste pipes together, a locking ring for compressing the sealing ring into resilient locking and sealing engagement with the waste pipes, and a latching mechanism for securing the locking ring in place with the seal ring resiliently compressed a predetermined degree. The latching mechanism maintains the locking ring secured to the end flange structure and comprises at least first and second latching projections on the end flange structure that extend towards the locking ring, and projection guiding cam surfaces formed in the locking ring. Each projection guiding cam surface terminates in a notch-like latching recess.
