Abstract
347,352. Road signals for controlling traffic. HUIZINGA, W., 22, Havenstraat, Amsterdam. Feb. 12, 1930, No. 4769. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 14, 1930.] [Class 118 (ii).] A road-traffic control signal comprises a number of concentric neon tubes 5 .. 13, those of odd number being green and those of even number red, and a switch 18 driven by an electromotor 21 is adapted to light simultaneously all the red tubes and subsequently to cut them out one by one, the same cycle being then imposed on the green tubes. Other colours may be used in addition. The switch member 18 co-operates with contacts 19 to short circuit the neon lamps successively, the lamps and contacts 19 being interconnected with the high-voltage cables 14 of the transformers 25, 26. The drum 18 may comprise adjustable rings, and the contacts may be adjustably arranged to vary the duration of the short circuit. Manual control may be super-imposed for emergency signals. Trams may secure priority by the automatic operation by the tram of contacts placed in advance of the crossing. The signals may be combined with signals for pedestrians.
