Abstract

20,870. Walz, E. A. Oct. 12. Motor-road-vehicle signals; transparency, stencil, and illuminated signals. -Relates to direction-signal indicators for automobiles and other vehicles and of the kind in which the direction of intended movement is signalled by switching on electric lamps arranged in casings at the front and rear of the vehicle, and comprises various improvements in the lamp reflectors and casings, the combination therewith of a rear light and number plate, and an audible signal intimating to the driver the correct working of the direction signals. The front and rear direction indicators each comprise a casing 19 enclosing two electric lamps 33, 34 attached to brackets 31, a parabolic reflector 32 fitted with a cylindrical flange 37 being secured around each lamp. The casing 19 is closed at the front by a hinged door 21 carrying two concavoconvex lenses 36 for the lamps, the lenses being surrounded by flanges 35 which fit closely round the flanges 37 when the door is closed, thereby forming a substantially light-tight chamber for each lamp. The rear indicator is also fitted with a third lamp 28 arranged to illuminate the numberplate 26 through a slot 24 in the bottom of the casing 19, and also to form a rear light for the vehicle. The inner surface of each lens 36 is rendered opaque and reflecting by coats of red and white paint, except for a transparent portion in the form of an arrow. Contacts 16, 17 on the steering-wheel or other convenient part of the vehicle are closed by the driver when turning to the right and left respectively, thereby closing the circuit of lamps 33, 45 or of lamps 34, 46. In either case, an electromagnet 15 is energized and attracts a switch arm 64 to close the circuit of a buzzer 14 or like audible signal, which indicates to the driver that both front and rear lamps are lit. Should one of the lamps be defective, the reduced current in the circuit is not sufficient to actuate the relay, and the driver is informed by the silence of the buzzer. The rear light 28 is lit by closing a hand switch 62, and is independent of the push switches 16, 17,
