Description:
Three-wheel pipe cutter with the cutters in a cast or malleable frame. The movable jaw is adjusted by a screw. The construction provides ability to cut pipe by a rocking motion of the tool where it is not possible to make a complete rotation of the tool around the pipe. The patent claims the attachment of the adjusting screw to the movable jaw and aspects of the cutter wheels and pivot pins. The cutter wheels and pivot pins were the subject of a second patent (no. 287,899 granted Nov. 6, 1883).

Improved by patent no. 301,080; the tool was produced as the BARNES IMPROVED PIPE CUTTER.
