Abstract

2747. Leitner, H. Feb. 2. Drawings to Specification. [Cognate Application, 8224/12.] Lighting systems.-In double-batter trainlighting system, a rotary commutator switch driven one step by each operation of the main switch serves at each step to connect one battery to the lamps and the other to the dynamo, a resistance always being interposed between the dynamo and the lamps.
