A drain cleaning device includes a power unit and a drum assembly coupled to the power unit for rotation by the power unit. The drum assembly includes a base, a cable received in the base that is configured to be fed from the base and rotated to clean a drain, and a cover releasably coupleable to the base. The drum assembly includes a plurality of taper locks releasably coupling an outer peripheral portion of the cover and an outer peripheral portion of the base. Each of the taper locks is moveable between a locked position in which the cover is retained on the base and an unlocked position in which the cover is removable from the base. Each of the taper locks being biased toward the locked position.

A drain cleaner assembly including a base unit having a housing, a first portion of a drive arrangement supported by the housing, and a motor coupled to the drive arrangement, where the motor is operable to selectively drive the drive arrangement. A drum unit is removably coupled to the base unit. The drum unit includes a rotatable drum, a cable stored within the drum and selectively extendable out of the drum and into a drain, and a second portion of the drive arrangement, where the second portion of the drive arrangement includes a driven shaft extending along an axis of rotation of the rotatable drum, where the driven shaft is rotatably fixed to the rotatable drum, and wherein the first portion of the drive arrangement is configured to drive the driven shaft and the rotatable drum when the drum unit is coupled to the base unit.

The group of inventions can be used for removal of deposits in sewers and the simultaneous removal thereof in various pipelines, providing mechanization of the cleaning process in a sewage pipeline and eliminating the need for disassembling the drain system and manually cleaning it. A movable element and a cleaning tool mounted thereon, both arranged within the sewage pipeline, are moved along the sewage pipeline by means of a drive mounted outside the sewage pipeline and connected to the movable element. In the initial position, the cleaning tool is located at the end of the sewage pipeline, outside the sewage pipeline portion connecting the drain pipe with a riser. When the cleaning tool reaches the end position at the junction of the sewage pipeline and the riser, the drive and the movable element move the cleaning tool to its initial position.

A drain-pipe interface device is disclosed. The drain-pipe interface device may include a hollow profile defining a threaded portion located on an outer surface the hollow profile. The threaded portion is configured to engage with an opening associated with a drain-pipe, to couple the drain-pipe interface device with the opening. The drain-pipe interface device may further include a handle provided on the hollow profile. The handle may be used to rotate the drain-pipe interface device couple with the opening.

An apparatus for driving interchangeable flexible shafts. The apparatus having a stand; a platform coupled to the stand, the platform being configured to rotate around an axis of rotation; a disconnect affixed to the platform, the disconnect being configured to connect a rotary power source to a flexible shaft; and fasteners affixed to the platform, the fasteners being configured to releasably couple a reel for the flexible shaft to the platform.

A drain cleaning device includes a power unit and a drum assembly coupled to the power unit for rotation by the power unit. The drum assembly includes a base, a cable received in the base that is configured to be fed from the base and rotated to clean a drain, and a cover releasably coupleable to the base. The drum assembly includes a plurality of taper locks releasably coupling an outer peripheral portion of the cover and an outer peripheral portion of the base. Each of the taper locks is moveable between a locked position in which the cover is retained on the base and an unlocked position in which the cover is removable from the base. Each of the taper locks being biased toward the locked position.

A flexible shaft which has a plurality of metal sleeves having a smaller end portion and a larger end portion at opposite ends of the metal sleeve. One of the end portions has a plurality of protrusions whereas the other one has a plurality of apertures capable of accommodating a part of each of the plurality of protrusions. The smaller end portion of is partially inside the larger end portion of the next metal sleeve in the flexible shaft. Each metal sleeve is movably connected to the next metal sleeve using the protrusions and apertures. The apertures are notably larger than the protrusions in lengthwise direction of the flexible shaft which allows two adjacent metal sleeves to be in position where their rotation axes are not parallel.

A combination toilet unblocking/cleaning apparatus for providing both a toilet unblocking and toilet cleaning tool in one convenient unit. The toilet unblocking tool further includes an adjustable auger, a combined tongs, and a detachable rod. Wherein, the adjustable auger includes two drain cleaning cable connected to a slider and slidable held in an elongated sleeve member; and the detachable rod is removably attached to the adjustable auger to form a combined tongs, constructed in such manner that the rod member can be used individually as drain rod. Also, the combination toilet cleaning tool is using the combined tongs as a handle with a plurality of different detachable bathroom accessories. Accessories may include a brush, a plunger, and a scraper; in which the brush, the plunger, and the scraper are configured to be selectively and removably coupled to the combined tongs.

A sewer cleaning machine includes a power base with a motor and a drive mechanism, and a drum removably coupled to the power base. The drum includes a cable that is selectively extendable out of the drum and is movable between a first position, in which the drum is supported by the power base and coupled to the drive mechanism, and a second position, in which the drum is separated from the power base.

A sewer cleaning machine includes a frame, a drum rotatably supported by the frame, and a motor supported by the frame and coupled to the drum. The drum includes a cable that is selectively extendable out of the drum. The motor is operable to rotate the drum. The drum is configured to engage a surface to facilitate moving the sewer cleaning machine along the surface.
