ABSTRACT:
There is disclosed herein an apparatus adapted for use on a conventional four slide machine which allows one or more end portions of a length of stock to be threaded simultaneously with the forming of another portion of the stock to a desired contour. The apparatus includes a thread rolling head driven by a motor, both of which are secured to a compound slide which is mounted on a four slide machine and adapted to be reciprocated through the agency of a cam and cam follower arrangement provided on the four slide machine. This apparatus allows stock of any cross-sectional shape suitable for the formation of threads thereon to be fed into the four slide machine, an appropriate length severed therefrom and the end portions threaded while additional portions thereof are formed into any of a variety of irregular contours, all in a single operation, thereby eliminating the need for manually transferring the workpiece between separate machines or providing progressive work stations and associated workpiece transfer means, should such automated equipment be available.
