摘要： In a pipe perforating machine including a cutter head movable through a pipe and cooperating with shear blades carried by the machine frame, a cutter guide consisting of guide ways extending through the pipe and on which the cutter head is slidably mounted, a fixed support for one end of the guide ways, a movable support for the free other end of the guide ways which is detachable from the ways to permit the pipe to be threaded longitudinally over the ways, a fixture detachably mountable on the guide ways at the free end thereof and including a roller on an axis transverse to the pipe and engageable with the frame to support the free ends of the ways when said movable support is disengaged, while still permitting the threading of the pipe over the ways, the cutter head including a toothed cutter wheel and being movable outwardly from the end of the pipe, and a fixture carried by the frame and urged against the end of the pipe, and operable to catch and secure the cutter wheel against rotation as it emerges from the pipe, whereby when it re-enters the pipe, its teeth will always begin cutting perforations at the same distance from the end of the pipe.

摘要： A pipe perforating machine consisting of a bed adapted to support a pipe for movement longitudinally of itself, powered mechanism for driving the pipe in both directions, and a plurality of cooperating pairs of perforating elements carried in spatially fixed relation by the bed and operable to perforate the pipe as it is moved in either direction. At least several parallel rows of perforations may be cut on each pass of the pipe, and the pipe may be angularly indexed after each pass for cutting several additional rows of perforations during the next subsequent pass of the pipe in the opposite direction.
