Abstract

531,814. De-wirement indicator for trolleys of electric vehicles. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. Sept. 18, 1939, No. 26088. [Class 104 (iii)] [Also in Group XXXVI] The de-wirement relay of a trolley bus or the like, which is energized from the collected high voltage supply and which operates contacts in a low voltage indicator circuit has its frame connected to the intermediate conducting member of the usual double insulating system of the trolley bus electric gear. Specification 531,762, [Group XXXVI], is referred to.
