Abstract
608,360. Screwing-dies. HAYCOCK, H.J., and WILSON, H. G. C. Feb. 21, 1946, No. 5389. [Class 83 (iii)] A screwing-die 1 comprises in combination a body part having a bore of complete thread and a lead 5 to said thread, the thread being interrupted by gashes 4 which form cutting- edges 9 and extend from the lead into but not through the axial length of the thread leaving an uninterrupted complete thread portion 3, said gashes and cutting-edges being formed by axially-inclined recesses 6 in the face of the body part and breaking into the thread. The recesses 6 may be circular and may run out to the periphery of the die to form inclined surfaces 10 which, with the curved faces 7, serve to lead the swarf away from the cutting-edges. For a reversible die, similar recesses and cutting-edges 13 are formed,on the opposite face of the die, preferably staggered with respect to the edges 9.
