Abstract
300,109. Thurbau, T. W. July 10, 1928. Road - traffic signals on vehicles. - The electric horn, on a motor-vehicle is automatically sounded in the event of sudden emergency when the foot-brake pedal is depressed to the limit of its travel, but not when the pedal is depressed gently. The born circuit is closed when a spring d, adjustably secured to a clip e fastened to the lever-arm of the foot-brake, contacts with a metal plate b arranged on an ebonite block a on the footboard and connected through a switch to the horn.
