DIPPING HEADLIGHTS
AN INGENIOUS INVENTION Gradually the advantages of dipping headlights are becoming recognised. For some extraordinary reason manufacturers of cars have not provided easy adjustment of head lamps, so that their periodical checking is discouraged, due to the difficulties of carrying out what should be a simple operation. Headlights, after correct adjustment, soon become inaccurate, due to the slight sagging of springs, variation of loads, or through the head lamps being slightly altered, through being used as a hand-rest when pushing cars about a garage. An ingenious pneumatic system of dipping headlights has been introduced. As the reflector and the lamp bulb are the only two parts of the head lamp which have effect on the height of the beam of light above the road, this invention deals with the former. The illustration shows the device
clearly. The reflector is made in two parts, the inner is mounted on a couple of hinges, so that when the top of the reflector is pushed forward the beam of light travels downward. The reflector is operated by a small cylinder in which is a piston coupled to the reflector. With the aid of a small spiral spring the reflector is ’joked into position after the pneumatic pressure 1:o the piston ceases. Tt will be quickly recognised that the operating knob produces a partial vacuum in the cylinder which causes the reflector to dip. while by pushing the knob in the reflector is brought back to a vertical position. Summed up. a gentle push of the knob directs the light downward, and dazzle is removed.
