Abstract

324,796. Bates, F., and Bates, T. Jan. 19, 1929. Screwing - dies. - In an integral screwing - die the holes 3 which intersect the central screwed hole 2 to form cutting edges 4 are inclined to the axis of the hole 2 so that the cutting edges will be inclined to this axis. The planes containing the axes of the holes 3 are parallel to the axis of the screwed hole 2 and the axes of the holes 3 preferably lie outside the periphery of hole 2. The inclination may be in the opposite direction to that of the screw-thread as shown in Fig. 3, or in the same direction. The die may be split radially or helically as at 5 so as to be capable of heat contraction in the holder and the periphery may be provided with holes or flats. The screwed hole 2 is tapered at each end to give the die a lead when cutting.
