Abstract

26,953. Terry, F. H., Bigwood, H. M., and Brotherton Tubes and Conduits, Ltd. Nov. 23. Couplings.-Electrical continuity is secured between conduits and junction - boxes or like electric fittings by a longitudinally-split tapered member contracted by means of a nut, or two tapered split members as described in Specification 24,492/12, [Class 99 (i), Pipes and tubes, Joints &c. for], the tapered member or members a being provided on their interiors with sharp projections a<1> arranged annularly, spirally, longitudinally, inclined, or as points, to cut through the insulating-coating of the pipe and make a metal-to-metal electric connexion.
