SINGLE-PHASE CATENARY CONSTRUCTION Some interesting improvements in single catenary bracketand span construction have recently been brought out bythe Elmer P. Morris Company, of New York, and areshown in the accompanying illustrations. Fig. i ilkistrates. ^^trtiet Railway ,J:urnaJ FIG. I.— CONSTRUCTION FOR CURVES a type of bracket construction for curves which preservesthe vertical position of the supports for the working con-ductor. In this type the push-off or steady strain has beeneliminated, and a pull-off substituted which clamps aroundthe porcelain insulator at the end of the arm. The upperend of this pull-off is anchored to the messenger betweenthe suspender arms and the lower end secured to the trolleywire. In this way the strain is removed from the insulatorcarrying the messenger wire. There are secondary insula-tors on the arm on either side of the petticoat messengerinsulator. In case the main insulator fails these second-aries provide against the grounding of the line by insulatingthe messenger almost as effectively as the main insulator.
