Sept. 5, 1933. c. c. HUBER ANTIGLARE REFLECTOR FOR AUTOMOBILE HEADLIGHTS Filed Aug. 29, 1932 Patented Sept. 5, 1933 UNITED STATES PATENT OFFICE ANTIGLARE REFLECTOR FOR AUTOMOBILE HEADLIGHTS 1 Claim.

The present invention relates to an anti-glare reflector for automobile headlights, and it has for its principal object to provide a device that will remove the objectionable glare from oncoming motorists. This is accomplished by the reflector which is properly positioned above and partially around the source of light, or bulb. The objectionable glaring rays are either blocked at certain points or reflected rearwardly, in general, to the parabolic mirror surfaces, while a larger amount'of direct rays reach the reflector and behave as usual.

To these and other ends, the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claim at the end of this specification.

In the drawing:

Fig. l is a central vertical section through an I automobile headlight reflector provided with an attachment constructed in accordance with and illustrating one embodiment of my invention;

Fig. 2 is a horizontal section on the line 2-2 of Fig. 1, showing the reflector attachmentin position above the bulb;

Fig. 3 is an enlarged side elevation of the attachment removed from the lamp;

Fig. 4 is a plan View, and

Fig. 5 is a front view, showing the upwardly inclined plane surface and also the abrupt curves.

Similar reference numerals throughout the several views indicate the same parts.

Referring to Fig. 1 of the drawing, 1 indicates the casing of an automobile headlight having the interior in the form of a parabolic reflecting surface 2, this surface being positioned in the rear of a front glass or lens 3. The electric lamp or bulb 4 is secured to the casing in a well known and usual manner, and current is supplied to the lamp by wires 5 running to the storage battery.

In the practice of my invention, I have positioned above and partially around the bulb 4 a reflector 6, the shape of which tends to throw part of the rays of the lamp or bulb downwardly and rearwardly to the parabolic reflector. This includes the flat inclined surface 7 which starts above and in front of the focal point of the main reflector and terminates in a tapering and curved portion 8, towhich is attached one of the supporting elements 9, said supporting 5 elements being, in the present instance, secured to a split spring ring 10, as at 11.

On either side'of the flat portion 7, I provide abrupt curved portions 12. These abrupt curved portions of the reflector merge tangentially with forwardly converging side Wings 13, said wings tending to prevent lateral dispersion of the direct rays from the bulb, and are so fashioned as to lend themselves to the general scheme of so reflecting the major portions of the rays from the light source that they will be kept low and out of the visions of drivers and pedestrians at the sides.

The front portion of the attachment is open as at 14, so that the direct rays of the bulb or light source may be utilized.

I claim as my invention:

The combination with a headlight lamp embodying a parabolic reflector, a lamp socket and a lamp in the focus of the reflector, of a reflecting and shielding hood encompassing the lamp and embodying an open bottom, laterally rearward open portions, forwardly converging side portions leaving an opening at the front in line with the lamp, and a forwardly and downwardly inclined top portion merging with the side por- 9 tions, all such reflecting portions being thus disposed in planes converging forwardly on three sides to intersect the horizontal geometrical axis of the lamp, and supports for the hood cooperating with the lamp socket.

CHARLES c. HUBER.
