  • Patent number: 4006521
    Abstract: A pipe remover for extracting a buried pipe from the ground by pulling an exposed end. The remover includes a grasping dog which engages the exposed end and a pushing dog which engages the buried trailing end. The two dogs are connected by a drawing element. By pulling outwardly on the drawing element, the pulling force is divided between pulling action on one end and pushing action on the other end. The pipe is usually extracted without breaking but, even if it breaks, is pushed through. The pipe may be simultaneously replaced by attaching a new pipe to the trailing end of the pushing dog.
