Abstract
831,497. Signalling devices for road-traffic vehicles. PAUK, W. Sept. 19, 1956 [Sept. 22, 1955], No. 28655/56. Class 118 (2). A vehicle signalling device comprises an assembly of three lamps 6 (amber), 7 (red) and 8 (green) arranged to be visible from the sides of the vehicle to indicate, especially at intersections when the vehicle is stationary or moving slowly, the intention of the driver to pedestrians and to the drivers of other vehicles, the amber lamp indicating " caution " (when the engine is idling), the red lamp indicating " danger " (when the engine has been " revvedup ") and the green lamp giving an " all-clear " signal (when the brakes have been applied). Fig. 2 shows the circuit connections of the device and the arrangement operates as follows. On closing the ignition switch 12 the battery circuit to the amber lamp 6 is completed via the dynamo 9 and cut-out 10 and, at the same time, the winding 15 of a relay 16 is energized, opening contact 17 and closing contact 18 and causing condenser 19 to charge to the battery potential. When the engine is " revved-up " the dynamo voltage opposes the battery voltage resulting in the extinction of the amber lamp and the reversion of contacts 17 and 18 to the position shown, the charge on condenser then flowing through the winding 21 of a second relay 22, via a resistor 20 giving a time constant of about 4 seconds, and causing contact 23 to close and complete the circuit to the red lamp 7 which remains illuminated until condenser 19 is discharged. When the brakes are applied the brake switch 13, in addition to switching on the conventional stop lamp 14, operates the parallel connected green lamp 8 and also energizes a second winding 24 on relay 16 causing contact 17 to open and contact 18 to close, the former ensuring that the red lamp 7 is not illuminated and the latter allowing condenser 19 to recharge so that when the brake is taken off the de-energization of winding 24 allows the contacts 17, 18 to reverse and the red lamp 7 is again switched on, the amber lamp 6 being either on or off depending on the engine speed. By replacing the relay 16 by two separate relays the amber lamp 6 may be prevented from being energized when the circuit of either of the other two lamps is completed (Fig. 3, not shown).
