  • Patent number: 6058547
    Abstract: A device for removing objects from a contained area or pipeline. A cutting means comprising at least one rotating, semi-rigid cutting arm of sufficient diameter, length, and material such that it is rigid enough to cut an object while having sufficient flexibility to avoid damaging an interior wall of said pipeline and to increase cutting area during operation. The cutting member, attachable to a shaft which is rotated by a standard motor, rotates concentrically with a longitudinal axis of the pipeline causing the semi-rigid cutting arm to move and flex during operation. The device may be employed inside a pipeline in both axial directions toward either end of said pipeline.
