Abstract
A carriage having rotary cutter wheels is mounting for reciprocation on a frame adapted to be rigidly secured to a pipe casing which is desired to be split along a line parallel to its axis. A hydraulic motor is mounted to the frame at one end of the carriage. A rotary crank driven by the motor is coupled to an arm which is also coupled to drive the carriage in a reciprocating motion. An adjustable hydraulic valve controls the speed of the motor, and thus the speed of the cutter. An adjustable stabilizer is mounted to the frame to stabilize the cutter by bracing against the carrier pipe within the casing.
