ABSTRACT:
Apparatus for removing the internal bead from a polyethylene pipe joint, that has been fabricated by the fusion process, comprising a torque tube of sufficient length to reach from the open end of the pipe to the joint from which the internal bead is to be removed. At the distal end of the torque tube is a cutter head, which includes a blade set at the proper angle to contact the inner surface of the pipe. This blade is mounted on an arm which has a hub to which the torque tube can be attached. A support frame has two legs and is pivoted to the cutter arm in such a way that when the torque tube and cutter arm are turned counterclockwise, the blade is pulled away from contact with the internal surface of the pipe. When the torque tube and arm are turned clockwise, the arm rotates about its pivot on the support frame and comes into a position such that the blade is opposite the support legs, and locks against a stop pin. The cutter blade in that position is pressed against the inner surface of the pipe. At the proximal end of the torque tube which extends outside of the open end of the pipe, a handle is provided for rotating the torque tube. The handle is attached to an outer tube, which is adapted to slide along and be locked to the torque tube. The outer tube which supports the handle also supports a plate which carries three angularly spaced arms of adjustable radius. These arms centralize the torque tube at the handle end.
