Pipe cleaning machine
摘要:
An improved pipe cleaning machine of the type which uses an elongated flexible coil spring or plumber's snake formed of helically wound spring wire which is housed within a rotatable spring storage reel, or drum, and is withdrawn therefrom for insertion into the pipe to be cleaned. 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.
