Application filed January 27, 1917. Serial No. 144,945.

To all whom it may concern:

- Be it known that I, BAYARD T. MERRILL, a citizen of. the United States, and a resident of Alderton, in the county of Pierce and- State of Washington, have invented a certain new and useful Improvement in Auto mobile-Headlights, of which the following is a specification.

My present invention relates generally to headlights, and more particularly to automobile headlights, my object being to provide means whereby all upwardly directed.

rays may be cut ofl at certain times and thus all glare eliminated in order to avoid collisions and other accidents ordinarily due to the light blinding of pedestrians and drivers of other automobiles.

In carrying out my invention I preferably provide means supplemental to the usual reflecting surface, and axially disposed light source, whereby when the latter is extinguished, only those rays which are downwardly directed will be givenout, so that, while the roadway remains suficiently lighted, all blinding-glare is eliminated.

lln theaccompanying drawing illustrating the preferred manner in which my invention is carried out 'Figure 1 is a front elevation of my improved headlight, and

Fig. 2 is a vertical section taken therethrou h substantially on line 22 of Fig. 1.

Re erring now to these figures, my improvementscontemplate the use of a headlight which, in so far as its general framework,'as seen at 10, and its axially disposed lamp bulb 11, are concerned, may be of the usual construction, the lamp bulb 11 being, however, in accordance with my improvements the main source of light, reflected outwardly through the usual lens 12, by means of the reflector 13.

In connection with such a construction, my invention contemplates the provision of a supplemental lamp bulb or light source 14, above the main lamp bulb 11, together with a shield 15 constituted, as shown, by a depending flanged portion of the casing and extending across the upper forward portion of the headlight, in front of the supplemental lamp bulb or light source 14, so as to obstruct the upper portion of the dirwt rays emanating from the said supplemental lamp bulb.

Furthermore, in accordance with my invention the reflector 13 consists of a plurality of angularly disposed reflecting surfaces the. direct rays of the said supplemental lamp, the upper portion of the dlrect rays being obstructed by the shield 15 which effectively conceals the lamp bulb or light source 14 from any point in advance of the headlight in line with or; above the plane of the lower edge of the mid shield.

, It is obvious that, in the normal use of the headlight, with the main lamp bulb 11 lighted, the supplemental lamp bulb may be either lighted, to be thus ready for use when the main lamp is extinguished, or may be extinguished at the time of the use of the main lamp and lighted simultaneously with thg eilrtinguishment of thelamp bulb 11.

1. A headlight having main and sugple' mental light sources, the latter located a ove the former, a casing having an opaque portion normally concealingthe said su ple mental light source and cutting ofl all horizontal' and upwardly extending direct rays therefrom, and reflecting surfaces within the casing common to said main and said supplemental light sources and arranged to direct all reflected rays from the supplemental lightsource in a downward direction.

2'. A headlight having main and supplemental light sources, the former of which is substantially centrally located, a casing having an upwardly extended upper rear portion in which said supplemental light source is located above the main source, an opaque shield extending across the up er front por tion of the casing and depending below the horizontal plane of the said supplemental light source normally concealing the su plemental light source and cutting ofl all horizontal and upwardly extending direct rays thereof, and reflecting-surfaces within the casing common to said main and supplemental light sources and arranged to direct all reflected rays from the latter in a downward direction.

3. A headlight having main and supplemental light sources, a casing havin an upwardly extended upper portlon in w ich said supplemental light source is located above the main source and having a depending flange forming an opaque shield extending across the upper front portion of the easing normally concealing the supplemental light source and cutting off all horizontal and upwardly extending direct rays there- 10 of, and angular reflecting surfaces Within the casing adjacent the main and supplemental light sources and arranged with respect to the supplemental light source to direct all reflected rays therefrom in a downward direction.
