  • Pipe cutter
    Patent number: 4149312
    Abstract: A pipe cutter for cutting installed pipes comprises a frame which can be fitted round the pipe and which carries a cutting tool and pipe engaging rollers; a feeding mechanism in the frame derives a drive from rotation of the frame around the pipe to feed the cutting tool into the pipe; a two-part ring is fitted around the pipe; and a one-way drive mechanism is provided between the ring and the frame, so that as the ring is reciprocated by means of a handle the frame is rotated to feed the cutting tool and so cut the pipe.
