Abstract
An attachment for apparatus that is arranged to cut threads on a tubular workpiece. The attachment includes a vertically oriented chute for delivering a stream of the tubular workpieces, by gravity, to a retractable pin on which the lowermost workpiece is supported. A reciprocating member is provided with spring biased jaws for gripping and removing the lowermost workpiece from the pin at the receiving station. The workpiece is moved into opposition with a plunger which transfers the unthreaded workpiece to the thread cutting apparatus. After the threads are cut, the plunger then retracts, together with the threaded workpiece, which is stripped therefrom by a second pair of spring biased jaws and carried away from the plunger so that the now threaded tubular workpiece may be discharged. The first and second pair of jaws move in synchronism with each other and in timed relationship with the transfer member so that, as the lowermost, unthreaded tubular workpiece is being remove from the receiving station, the workpiece that has been previously threaded is concurrently being moved towards the discharge point.
