Abstract

503,410. Overhead conductors for electric vehicles. WISEMAN & CO., Ltd., A., WISEMAN, A., and SIMMONS, W. Oct. 1, 1937, No. 26675. [Class 104 (iii)] Gaps between overhead conductors 8, 10 at their points of intersection are bridged by a pivoted switch 1 which can be moved into either gap. The frame on which it is mounted is connected by a cable 6 to the operating point. This switch may be combined with a multiple switch, Fig. 3, comprising two pairs of pivoted arms 11, 12 coupled by an insulated slidable rod and connected ,by a cable 18 to the switch 1, so that all the switches may be operated by a single control. Where pairs of positive and negative conductors cross, four pivoted switches for the crossings are coupled together by cable connections.
