Abstract

745,425. Road-traffic signals on vehicles. CRAIG, R. T. G.' Feb. 6, 1953 [Feb. 12, 1952], No. 3665/52. Class 118(2) [Also in Group XIX] Means for indicating from a moving body in accordance with its state of motion comprises an inertia - operated switch adapted to close one circuit and open a second circuit when the body is changing its speed or direction, while when the change of speed or direction of the body is arrested the one circuit is opened and the other closed. A device for a motor vehicle, for indicating to pedestrians whether they should cross in front of the vehicle, comprises a casing 1 having two compartments illuminated respectively by lamps 3 and 4, one compartment having an amber glass carrying the word "STOPPING" and the other having a white or green glass with the word "CROSS". Also contained within the casing 1 is an inertia switch 6, a three-position switch 9 and a tell-tale light 10. Windows 1a and 1b indicate the functioning of lamps 3 and 4 when the unit is mounted forward of the driver. The switch 7 (Fig. 3) is the usual foot-brake switch for operating the rear "stop" light 8. When driving in a built-up area the switch 9 is moved to the right (Fig. 3) so as to render the device automatically operable by the foot-brake, on application of which the pilot light 10 is lit and the weighted pendulum switch 6 swings forward to light lamp 3 and illuminate the "STOPPING" sign. When the vehicle comes to a standstill the switch 6 is restored to its normal position and is maintained in that position by the spring 6c, thereby lighting lamp 4 and the "CROSS" sign until the brake is released. By placing switch 9 in its mid-position the device may be thrown out of action when the vehicle is travelling on the open road, and by moving it to the left (Fig. 3) a signal may be given when the vehicle is stationary with the foot-brake not in use. A small modification (Fig. 4, not shown) comprises the use of a relay operated by the pendulum switch 6 the relay contacts controlling the lamp 3. Instead of using a pendulum a mercury switch may be mounted for inertia operation to constitute the switch 6. To indicate change of direction the inertia switch is mounted so that its direction of movement is transverse to that of the moving body. By changing over the spring 6c so that the normal position of switch 6 is as shown dotted the device may be used to indicate acceleration. Or by suitably positioning the inertia switch changes of direction or elevation in a vertical plane may be indicated.
