The cable finally rests in thegrooves of these sheaves. The principalfeature of design of these saddles con-sists of the provision for changing insu- lators, in case one should be broken, andthe elimination of inflammable design of the anchors at the endsof the two new cables embodies practi-call\- the same ideas as contained in thedesign of the saddle. Two steel beamsare set in concrete foundations and theirtops are back-guyed by iron straps intoconcrete blocks. Six porcelain line insu-lators are mounted on cast iron pins andbolted to the upright beams. A steel. frame-work is bolted to cast ironcaps, which are cemented to thelops of the insulators. The cableterminates around an iron sheavewhich is strapped to a system of springsand beams whicli is ulliniately bolted tothe steel frame on the insulators.
