' HEADLIGHT FOR AUTOMOBILES Filed July 17, 1928 LE.F uwers Patented Oct. 7, 1930 UNITED STATES PATENT OFFICE JOHN E. rownnsyor LYoNs, NEBRAsKA, ASSIGNOR or ONE-HALF r HANS An'rrrna 1 NELSEN, or LYo s, NEBRASKA HEADLIGHT FOR AUTOMOBILES Application filed July 17, 1928. Serial No. 293,327.

Another object of the invention is to provide a headlight wherein one bulb may be extinguished, and wherein means will be provided for deflecting the rays of the other illuminated bulb in a direction not only to preventthe blinding effect upon approaching drivers, but also illuminate the side of the roadway. Another object of the invention is to provide a device of this character which is simple.

in construction, eflicient in operation, durable and one which can be manufactured at a very small cost. 7

lVith these and other objects in View, this invention resides in the novel features of construction, formation, combination and arrangement of parts to'be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which V Figure 1 is a horizontal sectional view through a headlight showing the same equipped with the device.

Figure 2 is a side view of the device removed from the headlight.

Referring to the drawing 1 designates the" casing of the conventional form of headlight and in which is mounted the usual parabolic reflector 2, there being a lens 3 closing the reflector, as usual. w

Suitably fitted in the reflector is a plug socket 4 having carried thereby divergently 40 arranged sockets 5 and 6, said sockets having detachably engaged therein bulbs7 an d 8, respectively. Current is furnished through the sockets for illuminating the bulbs through wires 9 which are connected to aswitch, not

shown, which may be of any well known type capable of operating to permit both bulbs to be illuminated in each headlight or just one in each headlight, as the occasion may re- 3 uire. I

zontal planes within the reflector and suitably fixed to the plug 4 is a reflector plate 10 formed from suitable polished sheetvmetal,

and preferably of the shape shown. This reflector plate is disposed vertically and is of such size that it will elfectively shield the bulbs from each other.

It will be obvious that where both bulbs are illuminated the rays therefrom will be reflected in a direction to illuminate the roadway for considerable distance in advance of the car. However,when it is desired to dim the headlights to prevent the rays from blinding the driver ofan approaching car it is only necessary to extinguish the bulb 7 upon the right hand side of the plate 10,

whereupon the rays from the bulb 8 upon the left hand side of the plate will be reflected by the plate to the left side of the reflector and thence diagonally with respect to its lon- 'gitudinal axis to the right, as indicated in dotted lines in Figure 1. In this manner the o rays will be deflected from the center of the roadway to the side thereof, thus permitting the driverto note the condition of the right hand side of the roadway.

From the foregoing, it thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description and it will be understood that various changes in the: size, shape and proportion and minor details of con struction may be. resorted to without depart-v ing from the spirit or sacrificing any of the advantages of the invention.

What is claimed is A lighting unit for headlight-s comprising a plug socket and integral lamp sockets extending. therefrom in divergent relation, and a flat pear-shaped plate rigidly attached at the smaller end to the outerend of the plug socket and projecting outwardly therefrom to lie between lamp bulbs fitted to the lamp sockets; i

In testimony whereof I alfix my signature.
