Abstract

641,826. Electric lighting devices for cycles. BIRMINGHAM SMALL ARMS CO., Ltd., GOLDSCHMIDT, R., and WOOD, A. E. Jan. 14, 1948, Nos. 1077, 29866, 29867, 29868 and 29869. [Class 136 (i)] [Also in Groups XXXV and XXXVII] The lamps 39, 42 of a pedal-cycle are arranged to be lit by a dynamo 38 and a battery 40, respectively. With the switch 41 closed and the cycle stationary, lamp 42 is lit through a centrifugal mercury switch (see Group XXXVII) connected between earth and the terminal 9. When the cycle reaches a certain speed, the mercury switch cuts out the battery circuit and lamp 39 remains lit from the dynamo.
