Abstract
352,770. Road signals for controlling traffic. STERNBERG TRAFFIC-AUTOMATEN CO. GES., 1, Rosastrasse, Freiburg, Breisgau, Germany. Aug. 7, 1930, No. 23656. Convention date, Aug. 7, 1929. [Class 118 (ii).] In traffic-control signals at street crossings automatically actuated by vehicle-operated road contact members 3, 4, actuation by vehicles passing away from the crossing is prevented by arranging the members 3, 4 close together so as to be depressed simultaneously by the vehicle wheel 1, and by arranging that the depression of the first member 3 by a vehicle passing towards the crossing energizes a coil 8 and couples a hook 12 with a mercury switch 13, 14, while depression of the second member 4 energizes a coil 16 and lifts the hook 12 to rock the switch 14 and close the circuit of the signal lamp 19.
