Abstract
16,318. Edwards, E. A. July 12. Couplings.-Electric continuity is ensured in metallic conduits by driving a split tapered ferrule a between the spigot b and socket c. The ferrule may be flanged as at f, Fig. 1, to facilitate removal, and serrations e may be provided inside and outside the ferrule to give a better bite into the tubes of the system.
