Multiple Way Insulating Sleeve as Separator between Conductors on Cable Joints.

19,212. Mitchell, R. B., and Cooper, F. J. Aug. 25. Couplings.-To separate and insulate the bared electric conductors at the joint of a multiwire cable, there is threaded upon the cable before the joints arc made a multiple-way insulating-sleeve of porcelain &c. having ducts F communicating one with each cable-way E to prevent the formation of air-spaces while the sleeve is being filled with insulating-compound. The ducts are arranged as shown so as to lengthen the leakage path between the conductors, and lugs G, Fig. 2, are formed upon the sleeve to maintain it in a central position in the joint box.
