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an elongated, flexible coil spring or plumbers snake formed of helically wound spring wire which can be controllably withdrawn from the device for insertion into the pipe to be cleaned.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.
