6331. Browne, J. R., and Bayliss, F. W.; March 21. Screw couplings; sleeve joints.-In joints for conduits for electric conductors, a diagonally split steel or like ring c, preferably of hollow crosssection, is caused to grip the tube d by screwing up the internally tapered nut b. The movement of the ring c during this operation scrapes away any enamel &c. from the tube d, ensuring metallic contact. Red lead may be applied to render the joint water-tight.
