Abstract

796,115. Screw-sockets. HELI-COIL CORPORATION. April 12, 1956 [May 25, 1955], No. 11149/56. Class 89(1) [Also in Group XXII] A screw-thread is formed in a bore 51 in a nut or boss 50 by forcing into the bore, (Group XXII), a wire-coil 53 having a cross-section composed of inner and outer triangular-portions 54, 55, and a rectangular-portion 56 on which the triangles are erected. The inner triangular-portion forms the screw-thread and the outer triangular-portion bears against the wall of the bore to provide a high frictionalresistance to axial and peripheral movement. The intermediate rectangular-portion provides surfaces with which the coilconvolutions can bear upon one another and take up the axial thrust applied for pushing the coil into the bore. The coil may be contracted before insertion into the bore 51.
