ABSTRACT:
The present sewer pipe cleaning device may be used on a conventional plumber's fish tape. The device comprises a rowel-like member having curved tines thereon, with the axis of the rowel-like member being transverse to the axis of the sewer line. The rowel-like members are rotatable mounted on a non-rotatable member in such manner that the rowel-like member may be moved into the debris which is clogging the sewer pipe. The rowel-like members each have a plurality of curved, sharpened tines, secured thereto which tines extend in the same direction, with the tines of each rotatable member lying in a plane perpendicular to the axis of the respective rowel-like member. The rotatable members are spaced apart so they will rotate in apertures in flanges on the mounting member, when moved in one direction. The device is so constructed, that reversal of the movement of the fish tape, will lock rowel-like members against rotation, so the debris which has been engaged by the tines can be pulled to the opening of the sewer line and removed as the tape is removed.
