Abstract

778,327. Screw sockets; dowels. PHILLIPS, E. April 12, 1955 [April 9, 1954]. No. 10473/55. Classes 89 (1) and 89 (2). A self-tapping, internally-threaded insert A, Fig. 1, of wear-resisting material for insertion in a hole in a piece of softer material, comprises a substantially cylindrical body with external helical ribs 13 at an angle of from 5 to 45 degrees to the cylinder axis. The insert has a plain pilot part 11 bevelled as at 12, and may have a slit 14 to lock an inserted screw. The hole formed in the softer material is such as to receive the pilot, and the insert is then pressed in, using a disc 19, Fig. 3, which has a projection 20 seating in bevel 16, and a projection 21 which deforms the flutes cut by the insert adjacent the surface of the hole, thereby looking the insert in the hole. In a modification, the insert C, Fig. 10, secured in hole 33 in member 17b, has a cylindrical-projection 28 serving to locate a member 30 to be secured to member 17b by screws 23 engaging a number of inserts C. The locating-holes in member 30 may be bushed by inserts 31 having plain bores.
