DANIEL C. DOZIER, OF NORFOLK, VIRGINIA.

' VEHICLE HEADLIGHT.

Application filed November 5, 1923. Serial No. 672,899.

T all whom it may concern:

c it known that I, DANIEL U. DOZIER,

a citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Vehicle Headlights, of which the following is a specificat-ion.

My invention relates to vehicle headlights.

The object of the invention is toprovide an efiicient headlight for automobiles which contains advantageous features which will be more fully described herein and specifically pointed out in the claims hereunto annexed recourse being had to the accompanying drawing forming a part of this specification in which Figure 1 is a sectional view of one form of my device taken on the line 1 in Figure 2.

Figure 2 is a front view.

Figure 3 is a rear view.

Figure 1 is a front view detached from the incandescent lamp.

Figure 5 is a plan of my device removed from the lamp. 7

Figure 6 is a plan of the colored light transmitting are shaped plate.

Figures 7, 8 and 9am elevations of modified forms of shades.

Figure 10 is a sectional view of a modified v form of half shade or lamp cover.

Figure 11 is a sectional view of a reflector of a headlight showing the manner of distributing the rays of light from my device.

Figure 12 is a front view of the same.

In the drawing like reference numerals indicate similar parts in all the several views 1 represents an elevation of an incandes cent lamp used for headlights of automobiles and is provided with a base 2 fitting into the socket 8. in the ordinary manner.

4: is a shellor half shade having a straight or horizontal front portion and a rounded rear portion, as shown in Figure 1, while in Figure 10, I show a modified form 5 wherein the. whole shade is semi-elliptical and which will be described hereafter.

6 is an orifice which partly surrounds the lamp base 2.

7 is a circular shaped spring soldered, or otherwise fastened to the inner rear portion of the shade 4 or 5 and is adapted to have a spring fit over the base 2 to hold the shade in place upon the lamp.

To further support the shade and allow for the insertion of any size lamp, I provide a spring or springs 8 extending across the diameter of the shade, from side to side, as at 9, and located under the lamp 1 as shown in Figures 1, 2 and 10 thereby holding it in a yieldable manner and capable of being distended according to the size of the lamp which is inserted over the spring until the spring 7 engages the lamp base 2.

10 is a slot placed in the top of the shade 4.- or 5 and extends, with decreasing width. about two thirds of its circumference and is shaped like a segment of a circle formed by a chord and the are of a circle.

Over the opening 10 I place a curved glass or nica plate 11 of one. or two colors, for example, one. red portion 12 and a green portion 13, Figure 6, for emitting a crescent shaped glow on the head light reflector 'and lens, as shown in Figures 11 and 12,

also for causing different colored rays to be cast upwards or at an angle as will be described hereafter.

The glass plate 11 may be of even width throughout or have reduced ends 11 if desired, shown in Figure 6. The plate 11 is inserted under the ispring tongues 14 and pushed towards the rear of the shell or shade 4c or 5 until its outer edge slips below the projection 15 which holds it in place. If the glass 11 is divided into two colors or perhaps three colors, it may be moved so that any color may be used, if desired.

16 is a narrow strip formed with the shade 4e and terminates with the disc or plate 17 and is for the purpose of shading the direct rays from the source of light, as in Figure 2, while in Figure 10 I make the shade so that its outer edge will extend a little below the horizontal centre line 18 of the lamp 1.

19 is a depression which forms a knob on the inside of the shade 5, Figure 10, and is for the purpose of resting upon the upper part of the lamp and assists in keeping it in place and allowing for an air circulating space for keeping the shell or shade cool.

In Figure 1, 20 represents, by dotted or broken lines, the location of a possible side opening in the shell 4 or 5, and 21 are similar lines showing an apronfor further shading the light'if it is desired to use such.

In Figure 9 I show an inclined light defleeting shade having an angle 22 of approximately 76 degrees. I also show the top of the shade perforated at 23 arranged to form a shape like that at 10 and occupying approximately the same area.

In Figures lland 12 I show my invention within the reflector of a headlight, as at 24, showing the reflection of the rays in the ordinary manner, the arrows 26 indicating the upward or angular rays through the glass 11 passing through a suitable orifice 1n the top of the reflector, as at 25, though my device may be used without'the reflector 24, if desired.

The colored rays through the glass 11 are thrownat an angle ahead of theautomobile and if the tail lamp should go out, a following car driver may see them and would identify fire apparatus if so equipped as well as ordinary automobiles. The shape of the slot 10 covers a part of the reflector 24 with a crescent shaped light area, as at 25 in Figure 12, and if suitable marks or letters are placed on the plate 11, they would be visible in a magnified manner upon the reflector. In this manner, one car may be distinguished 'from another by properidentifying marks.

My device may be arranged so that the light may be thrown to the right or leftacting also as a light diffuser and the colored rays are so distributed that the will be raised so as to bedistinguished above the bright lights of oncomingcars and preventblinding.

My invention can be used in headlights having ordinary cheap glass and my. invention maybe readily replaced and be free from in ury. It also provides a substitute for expenslve glass lenses, will eliminate 1. In combination'with an electric incandescent lamp, of a shade adapted to be spring fitted around the bulb of the lamp, a segmental opening therein, a multi-colored light emitting medium thereover, and spring means for holding the multi-colored medium over said opening.

2. In combination with an electric lamp, a halt shade or shell therefor, double spring means for holding the same to the lamp, an openin on the shade and over said lamp adapte to direct the rays upwards and at an angle, light transmitting means over said "opening, means on said half shade for kee ing the lamp from direct contact therewith, and a disc formed from the shade adapted to cover the endu-g the lamp for throwing the rays below a horizontal line from the centre of the lamp.

In combination with an electric lamp and its reflector, of a shade adapted to be secured to two portions thereof, spring means for both of said parts, an opening in said shade, and a colored light emitting medium for casting a glow upon said reflector of approximately a crescent shape.

4:. A headlight and in combination with its lamp and reflector, of a shade for the lamp having means for directing White rays downwards and sideways. an opening in the shade, a double colored glass cover for said opening adapted to emit colored rays up-.

wards, at an angle and upon a part of said reflector, and spring holding means for the shade positioned at the end and under said lamp. 7

In testimony whereof I have hereunto affixed my signature.

DANIEL G. DOZIEB.
