Abstract
4899. Burnett, H. R. March 7. Electric railways and tramways with safety appliances for guard - wires, trolley wires for electric traction, and other conductors. Conductors. - The insulated guard-wires Bare earthed through the coils P, or through a fusible wire of an automatic switch which serves to break the feeder circuit F to the trolley wires B, and in some cases, the earth connection of the guard-wire is also interrupted when connection is made between the wires A, B. The main circuit is broken at the contacts G by the members I or H of the switch, under the influence of the spring J, when the catch L is released by the armature of the coil. Other forms of cut-out may be used such as an electromagnet or a falling weight released by the fusion of a wire. The earth connection of the guard-wire may be broken at the same time at the contacts Q by an additional bridge on the switch, so that if the appliances are used at each end of a section they will operate successively. In case either wire A or B breaks, the connection between them is made by the loop Z attached to the trolley wire, or by a plunger V attached to one wire working in a tube T fixed on the other wire, insulated sleeves or linings Y<1>, U being provided to keep them out of contact under normal conditions.
