Patent number: 9505040Abstract: A pipeline debris shearing device includes a forwardly positioned, self sharpening, wear compensating, diameter conforming elastomeric member that forms a peeling edge having a negative rake angle to peel away debris from the internal wall of a pipeline. The peeling edge is formed at the point of meeting between a concave-shaped, curved forward face surface and a substantially straight outer peripheral surface. Radial slots may be provided to lessen the force being exerted on the peeling edge and provide for bypass flow to carry away debris removed by the peeling edge. Spaced-apart narrow stripper teeth may be added to help in removing harder deposits of debris. The peeling edge may be arranged substantially perpendicular the central longitudinal axis of the pipeline pig or arranged oblique to it. Further, the peeling edge may spiral about at least a portion of the pipeline pig.Type: GrantFiled: July 27, 2015Date of Patent: November 29, 2016Assignee: TDW Delaware, Inc.Inventors: William J.
