Abstract

404,468. Trolly poles for electric vehicles. BRECKNELL, WILLIS, & CO., Ltd., and WILLIS, A. M., 59, Victoria Street, Bristol. Jan. 30, 1933, No. 2910. [Class 104 (iii).] A trolly pole is prevented from rising excessively on jumping the conductor by a spring 21 mounted on a rod 22 between a nut 24 on the rod and a lug 23 on the pole. The rod lies below and parallel to the pole, passes loosely through the lugs 23, 25 on the pole, and is pivoted to a link 26 which is pivoted to a strap 27 on the rotary base 7 of the pole. Specifications 404,466 and 404,467 are referred to.
