GUTTING OFF AND REAMING MACHINEFOR PIPE AND TUBES A machine for cutting off and reaming all sizes of pipe andtubes up to 2 in. has recently been developed by the OsterManufacturing Company, Cleveland, Ohio. This machine isprovided with a large single wheel tube cutter which is sta-tionary and is mounted on a steel pinion resting in a bronzebearer. The pipe to be cut off rests on a pair of rollers and by. Oster Cutting Off and Reaming iVlachine for Pipe and Tubes a turn of the hand wheel at the top of the machine is broughtin contact with the cutting disc. The speed of cutting off is regu-lated by a slight pressure on the hand wheel. The rollers whichsupport the pipe rest on the bottom of a yoke which slides upand down in the frame. The disc cutter can easily be removed Mav, 1914 RAILWAY AGE GAZETTE, MECHANICAL EDITION 269 for sharpening or renewal. The gage rod is adjustable for tliedilierent lengths of pipe to be cut. In reaming, the pipe isheld in the vise jaws shown, which are opened or closed by amovement of the hand wheel at the side of the vise. This openvise facilitates the quick changing of work. The pressure ofthe pipe against the reamer is brought about by a slight pres-sure on the handle mounted behind the vise wheel. This handlealso moves the vise back and forth. The reamer is held in placeby a set screw and can easily be removed for sharpening when
