Abstract
609,485. Making bolt-hole bushes. VAES, M., and VAES, P.-E. May 7,1945, No. 11657. Convention date, Jan. 27, 1943. [Class 83 (ii)] [Also in Group XXV] Sockets for coach and sleeper screws are made by profiling and coiling a strip, the joint at the meeting edges of the strip being sealed by pressure applied during formation or by the screw itself during insertion. The strip may overlap at 5, 6, Fig. 2, midway between two threads of the screw and sealing is effected by pressure against the forming mandrel 1. Instead of overlapping, the edges may be bevelled and abut. In other forms, the strip may overlap over the whole of the V-portion engaging the screw-thread or a cover strip 11, Fig. 8, may be employed giving a double thickness throughout.
