Abstract
Pipe thread cutting apparatus having combined simplified control means for positively controlling the position of the thread cutting chasers throughout the thread cutting operation. The control is effective to move the chasers to a desired closed position, to adjust the closed position for sizing, to recede the chasers to produce a tapered thread and thereafter move the chasers to open position upon completion of the threading operation.
