Abstract: An improved flying saw of simplified and more economical construction is disclosed which operates smoothly with reduced vibration and which performs in an improved manner at higher operating speeds. The machine has a main crank arm with a rotary saw blade at one end and an adjustable counterweight at the opposite end, a stabilizing crank arm with a counterweight, and a connecting rod causing the arms to rotate in unison. Both arms telescope to permit simultaneous adjustments of arm radius while screw jacks adjust the height of the crank axis relative to the work. The work is supported on a wheel having a special sliding-block eccentric which moves the wheel in a vertical direction to deflect the work into the path of the rotary saw blade. A quick-drop support bracket permits lowering of the wheel and its eccentric away from the path of the work in an emergency situation so that flow from the mill need not be interrupted.

Abstract: An improved pipe mill is disclosed having two cooling beds and a dual conveyor for delivering cut lengths of pipe from a saw to both beds in two paths, whereby the mill can be operated at very high speeds. A unique selector unit is provided having an oscillating deflector for diverting successive cut lengths of pipe from one conveyor path to the other in timed relation to the operation of the saw and having a special cam actuating unit which can be operated in three different ways to cause delivery of pipe to either one or both of the cooling beds. The cam unit includes a rotating cam wheel having a flat flange at one side and a contoured flange at the opposite side which is engageable with a cam roller or follower to cause reciprocation of the deflector with a dwell at each of its advanced and retracted positions.
