9341. Kando, C. de. April 20. Electric railways and tramways on the overheadconductor system. Conductors.-The rods holding the conductors at curves are arranged so as to prevent the conductor from rising or falling from the horizontal, as the tension in the line changes on account of thermal contraction and expansion, by hanging the conductor 1, Fig. 2, from a link 11 pivoted at 10 and 9 to a tie-bar 6 and a strut 5. The tie-bar and strut are pivoted at 7, 8 to the insulator, and arranged at such an angle that their axes meet at O in the horizontal plane containing the conductor 1. More than one bar of each kind may be used, or the struts alone may be duplicated, and in certain cases the rods may be arranged parallel to one another, Fig. 4. As shown in Fig. 6, the compression and tension rods 5, 6 may be hinged at 13, 14 to bellcrank levers 17, 18 and 19, 20, which are connected by toothed segments 21 or by a pin-and-hole device. When used for double wires, Fig. 8, to avoid breakage in the event of the contact-roller 24 fracturing, the tension mechanisms 26, 27 should be arranged to cross as shown.
