Abstract: An improved power driven waste line clean out apparatus of the type that includes an elongated flexible coil spring that is selectively rotated by a novel operating mechanism in a manner to permit sections of the coiled spring to be sequentially fed into and retracted from the waste line to be cleaned as the operating mechanism reciprocates back and forth along a pair of generally horizontally extending guide members mounted on the base of the apparatus. In operation, the coiled spring is first gripped by the operating mechanism in a manner to cause rotation of the spring about its axis so that a feed mechanism will advance a section of the coil spring into the waste line. The coiled spring is then released so that the operating mechanism can be returned to its initial starting position to enable additional sections of the coil spring to be advanced into the clogged waste line.

Abstract: A power driving waste line clean out tool which includes an elongated flexible coil spring formed from an elongated spring wire that is helically wound about a flexible water conduit.

Abstract: An improved apparatus for temporarily sealing a vent or overflow aperture provided in the upper portion of a fixture such as a wash basin, sink, bathtub or bidet so that a pneumatic or hydraulic type sewer cleanout device can be used to clear a blockage located in a sewer line downstream of the fixture by generating fluid pressure within the sewer line intermediate the blockage and the main water drain of the fixture. The apparatus is of simple construction and embodies an assembly made up of a pressure plate, a threaded tube and a wing nut which can be threadably advanced along the tube to cause the pressure plate to sealably engage the apertured wall of the fixture.

Abstract: An improved plumbers' tool of the type employing a helically wound coiled spring which is controllably inserted into waste lines to remove blockages. In operating the tool of the invention, a storage drum from which the clean-out spring is payed out is rotated, usually by a small electric motor, and the spring is clamped in a chucking mechanism so as to rotate with the housing. The improvement of the present tool resides in the provision of a unique actuating mechanism which provides a substantial mechanical advantage that enables the operator, using only one hand to grip a forwardly positioned stationary handle with the fingers and move a pivotally movable, rearwardly positioned handle with the heel of the hand to cause the chucking mechanism to positively engage the coiled spring in a manner to prevent slippage even under severe torque loading conditions.

Abstract: A drain cleaning device of the type that includes an elongated, flexible coil spring or plumbers snake formed of helically wound spring wire which can be controllably withdrawn from the device for insertion into the pipe to be cleaned. The device is provided with a novel storage reel or drum drive arrangement which includes a friction clutch mechanism that automatically disengages the drum drive mechanism from the drum so as to stop rotation of the drum prior to any excessive torque build up within the snake. The clutch mechanism is adjustably spring loaded so that the device can be easily adjusted for optimum use with springs of different diameters and rigidity. The storage container or drum can be rotated either by hand or by a motorized tool at relatively high speeds for long periods of time without excessive buildup within the plastic components of the device due to frictional engagement among the rotating parts of the device.

The machine of the present invention embodies a novel dual drive arrangement which enables the drum to be rotated and the spring wire, or snake, fed into the pipe either by means of a small electric hand drill, which can be affixed to one shaft of the dual drive arrangement, or by a hand crank which can be detachably interconnected with a second shaft of the dual drive arrangement.

Abstract: A feed control device for use in conjunction with plumbing tools of the type used for cleaning and removing obstructions from waste lines in which an elongated coiled spring wire, or plumber's snake, is advanced through the pipe and rotated. The feed control device includes a novel snake feeding mechanism movable into and out of engagement with the snake and includes a biasing means for yieldably urging removably mounted feed rollers, which form a part of the feeding mechanism, into driving engagement with the snake. A unique feature of the invention resides in the design of the feed roller holder assembly which permits the selection of rollers having either smooth peripheral surfaces, or, alternatively, surfaces having helical grooved formed therein. When the smooth rollers are used the rollers can be rotated within the holder assembly so that the snake can be driven forwardly or in reverse.
