HEADLIGHT.

Application fiIed April 14, 1926. Serial N0. 102,016.

This invention relates to improvements in headlights, and has particular reference to headlight adapted to be placed between the customary headlights of an automobile so as to give better illumination directly in front of the car and to the sides thereof in counterrlistinction to the customary headlights which direct a powerful beam a con siderable distance away thus leaving a dark spot directly in front of the car and leaving the sides of the road directly adjacent the automobile almost entirely tin-illuminated.

Another object is to produce a light of this character which may be made in a single stamping and one which will be economical to manufacture.

A further object is to produce a lamp which is neat in appearance and one which will not detract from the appearance of the car.

A still further object is to eliminate the necessity of employing a lens for the purpose of diffusing the light as is common Willi] other lamps of this type.

Other objects and advantages will be apparent during the course of. the following description.

in the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure I is a front elevatio'n of my lamp partly broken away so as to show the interior thereof,

Figure II is a cross-section taken on the line 2-2 of Figure I,

Figure III is a cross section taken at right angles to that of Figure II, and

Figure IV is a fragmentary perspective view showing the parallel reflecting sun faces.

lit is quite common to have automobile accidents occur due to poor illumination. litany of these accidents occur when cars are rounding a curve. with the result that the driver cannot see any object he may be approaching.

There are several lamps upon the market at the present time designed to overcome this difficulty. These lamps, however, employ a lens which so diffuses the light that much of the illumination is lost.

I have therefore produced a light wherein all of the rays are properly controlled and directed through a plain piece of glass, thereby securing the greatest possible illumination where desired.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred example of my invention the numeral 5 designates the shell, which also as shown, forms the body of my headlight. This shell has a reflecting inner surface and is stamped so as to provide curved sections 6, 7 and 8. These curved sections are parallel to each other as best illustrated in Figures I, III and IV.

In these figures, it will also be noted that these parallel portions are curved from end to end as well as from side to side.

At 9 I have shown an illuminating bulb c: rried in the customary socket 11. The bulb has been omitted from Figure III, but shown in dotted lines so as to better illustratc the invention.

Diverging reflecting surfaces are shown at 12 and 13. These diverging surfaces are secured to the outermost edges of the reflectors 6 and 8. At 14 I have shown a plain glass which is secured to the shell by a rim 16 between which shell and glass is positioned a gasket 17.

The result of this construction is that when placed upon the front of an automobile and properly illuminated as by a bulb 9, the rays of light coming from the bulb will strike the parallel reflecting surfaces 6, 7 and 8 and will be directed forwardly so as to give a maximum amount of illumination directly in front of the car upon which the device is installed.

At the same time, the reflector surfaces 1% and 13 will reflect some of the rays and. direct the same to the sides of the road upon which the vehicle is traveling.

It will thus be seen that I have devised a simple headlight which will accomplish all of the objects above set forth in an efficient manner.

It is of course obvious that the lamp may be made in sections or stamped as an inte gral unit Without departing from the spirit of the invention.

It is to be understood that the form of my invention herewith to be taken as a preferred example of my invention, and that various changes relative to the size, shape and arrangement of parts shown and described is extending transversely of and midway the ends of the body, with a section upon opposite sides of the middle section, curved diverging reflecting surfaces formed upon opposite sides and merging from the outer edges of the outer parallel reflecting sections and cooperating therewith so that rays reflected thereby will be directed forwardly in a line with said body and upon opposite sides thereof, a glass carried by said body, and a run for securing said glass thereto.

In testimony whereof I afiix my signature.

WILLIAM E. ALLEN.
