ABSTRACT:
The present invention relates to a power transmission device for use with a plumbing snake and a conventional hand-held drill motor to selectively extend, retract, and/or rotate the plumbing snake when positioned in a drain or sewer pipe system for clearing blockages or debris from the system. The snake is caused to extend or retract from the transmission by engagement of its coils with a threaded bore of a driven member engaged with a drive member rotated by the drill motor. Rotational motion of the snake is achieved through a brake device locking the snake and driven member together.
