Submarine Cable Patent No. 1,259,344, issued to Edwin W. Beardsley ofSan Francisco and Philip W. Ham of Oakland, shows a newform of submarine cable for the transmission of electric cur-. rents. This cable is composed of a central metallic support-ing cable covered with insulation and spirally wrapped aroundthe supporting cable are a plurality of insulated electric con-ductors. Surrounding the insulating conductors is a leadsheath which provides a water-tight case and steel armoredwires are spirally wrapped around the lead sheath, the jointsbetween the armored wires being covered. The function ofthe steel armored wires is to act conjointly with the centralmetallic supporting cable to relieve the electric conductors ofany strain.
