    Abstract: A telescoping parts manipulator comprising a telescoping tubular arm which is extended and retracted by a cable from a cable drum, and a workpiece engaging assembly which pivots on a wrist swivel axis carried at the end of the telescoping arm which engages molded articles in a molding machine. The telescoping arm is mounted to a slide box which moves forward and backward to allow engagement with a molded article, clearance of the tie bars in the mold, and movement towards a work station such as a conveyor belt. The cable is a hollow nylon tube which provides vacuum from a vacuum source through the telescoping arm to suction cups at the end of the arm which engage the molded articles.
