THREADING MACHINE DIE HEAD Abstract An annular thread cutting die head for a power driven threading machine is comprised of an annular support plate assembly supporting a plurality of radially displaceable threading cutting dies spaced apart about the axis of the die head, and a cam plate assembly coaxial with and pivotal relative to the support plate assembly to radially displace the cutting dies. The cam plate assembly is spring biased to pivot relative to the support plate assembly in the di- rection to radially retract the cutting dies, and pivoting in the latter direction is controlled by a keeper mounted on the support plate assembly and engaging a keeper track on the cam plate assembly. The keeper is mounted on the sup- port plate assembly for pivotal displacement about a keeper axis parallel to the die head axis, and pivotal displacement of the keeper is controlled by a lever mechanism actuated by a workpiece being threaded to provide for progressive dis- placement of the cam plate assembly and receding displace- ment of the cutting dies during the threading operation.
