Saunders Pipe-cutting and Threading Machine — Fig. 5 shows a pipe-cutting and threading machine made by D. Saunders' Sons, Yonkers, N. Y. It may be run either by hand or by belt. It is arranged so that pipe can be threaded and afterwards cut off, without removing any part of the machine. It is capable of cutting off and threading pipe up to 4 in. diameter, admitting the use of either solid or adjustable expanding dies. The cutting off arrangement is fastened to the face of the largo driving gear, between the gear and the die, in such a manner that either may be used without one interfering with the other. On the face of the large gear are ways for slides which hold V-shaped jaws of steel which are closed on the pit by a right and left screw, which adjusts the pipe to the centre of die: also steadies it when being cut off. The cutting-off arrangement is provided with a ratchet and pawl, and a short lever which projects through an opening in the gear, and twice in each revolution comes in contact with a trip, which causes it to feed the cutting-off tool, thus securing an automatic feed. There is provided a universal gripping chuck on back end of the machine for holding pipe, to which is attached a threaded sleeve which engages with a ring having threaded sections in it, these sections being movable by a lever, so as to be engaged with the threaded sleeve or not, as desired. Thus large pipes are forced into the dies at the proper rate.
