ABSTRACT:
An improvement in drain cleaning machines comprising a removable drum containing a length of coiled spring snake in which is inserted a flexible tube for carrying a flow of water to the free end of the snake. The hub of the drum is designed to mount upon a powered shaft adapted to injecting water at house pressure into the center of the hub, and thus into the tube, without leakage. In one embodiment, a swivel is formed inside the free end of the snake, to allow differential twisting between the tube and the snake, thus avoiding kinking of the tube.
