Image Number 3 for United States Patent #3985051.
A portable frame supports a mechanism for cutting pipes of various sizes. The pipe can also be grooved or bevelled at the same time. Initially a cutter cuts through a portion of a held, non-rotating pipe. Thereafter the pipe is rotated, or rolled, about its axic to permit the cutter to pass through the remaining portion of the cross section of the pipe to be cut. A single revolution of the pipe accomplishes the cutting thereof. Grooving or bevelling tools can be used simultaneously with the cutter to effect the grooving or bevelling of the pipe.
