ABSTRACT:
An improved pipe cleaning machine of the type which uses an elongated, flexible coil spring or plumbers snake formed of helically wound spring wire which is housed within a rotatable spring storage reel and is withdrawn therefrom for insertion into the pipe to be cleaned. The machine of the present invention embodies a novel one-piece rotatably driven spring storage reel or housing having a forward guide portion for guiding the dispensing and retraction of the spring and a rearwardly open spring storage portion. Extending into the rearwardly open reel and adapted for relative rotation therewith is an independently rotatable torque reaction element adapted to engage the spring and in cooperation with the reel, prevent the spring or snake from kinking or back-looping in response to torque build-up in the spring caused by the spring encountering an obstruction in the pipe being cleaned.
