  • Patent number: 4001911
    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.
