Abstract
452,108. Operating switches of overhead electric conductors. SKERRITT, E. M., and WATSON, T. M., Naranka Works, Orange Street, Sheffield, and BENNETT, S. C., 14, Glendare Road, Lidget Green, Bradford. May 15, 1936, No. 13245. [Class 104 (iii)] To ensure equal movement of a pair of connected frog switches, the switch levers 2 are pivotally connected by parallel links 3 to a floating lever 4 connected at its free end 6 by a cable &c. 7 to the actuating means. The distance between the two pivots 5 is equal to or less than the distance between the point 6 and the nearer pivot.
