Abstract

684,188. Making grub-screws &c. SIMMONDS AEROCESSORIES, Ltd. July 30, 1951 [Sept. 12, 1950], No. 22419/50. Class 83 (ii). [Also in Group XXV] Grub screws, screw plugs and like externally - threaded members that are self-locking are manufactured from cylindrical blanks by boring completely through, threading for about two thirds the length of the blank, turning down one end to form a thin - walled projection 4, applying a nylon or other locking annulus 6 to the projection and securing it in place by spinning over the end at 7. The remainder of the bore is then branched or otherwise machined to polygonal form and the screw may be counterbored at 9 to lighten it. In a modification this end of the screw is left imperforate.
