The chain passes over a sprocket on the block which carries a clutch so that the clutch slips when the block reaches one end of the slot and allows the chain to continue driving the rotary blade. A rotary sharpening disk is mounted at one end of the slot and is driven by the chain so as to rotate against the blade in a sharpening action while the block remains stationary.

Abstract: A pipe punch apparatus which generally comprises a punch housing, a punch means situated within the punch housing, and a collar. The punch housing is connected to a bi-directional hydraulic fluid pump means. Depending on which direction the pump is set, the pump releases fluid into the punch housing which causes the punch means to either extend from the punch housing or retract into the punch housing. The collar is connected to the punch housing by a connecting means so that a notch within the collar receives the punch means when the punch means is in the extended position. The parts are also relatively situated so that positioning the punch housing within a pipe will cause the collar to be located exterior to the pipe. Thus, as the punch means moves from its initial retracted position to its extended position, it will also punch a hole through the pipe.
