OTTO RI'IZ, OF BROOKLYN, NEW YORK.
HEADLIGHT.
Application filed March 24, 1926. Serial No. 96,933.
The present invention deals with headlights for automobiles or other vehicles and has for an object to eliminate the objectionable glare which is produced by the forms now in common use. It is proposed to prevent this glare and at the same time provide a structure which will give the desired flood headlight when it is needed, as for example when driving over country roads where full illumination is desired.
Reference will now be had to the accompanying drawings forming a part of the specification wherein:
Figure 1 is a frontelevation, partly in section, of a preferred form of my device.
Figure 2 is a section taken on the line 2-2 of Figure 1 and looking in the direction of the arrows.
In the drawings, a represents, conventionally, the outer casing of a headlight with a back 7) and a lens 0. A rim d is provided to secure the lens 0 to the casing.
The usual bulb which is provided in the reflector is represented as at e and is mounted at substantially the focal point of the reflector f and in the axis thereof.
Suitably secured to the reflector, as by soldering, welding, etc, is a horizontal refleeting partition the plane of which is well below the axis of the bulb and reflector. It has been found that the partition should extend below the lowest portion of the glass bulb. Pressed out of the partition, at its rear, is a hood h whiehconceals the bulb e from four sides but is sufiiciently spaced therefrom at its front, as to enable the bulbto be replaced.
Directly over the hood and as near as possible, is provided a second bulb i which serves as the full headlight bulb. By providing a horizontal partition, a relatively large area of reflector is had for the flood headlight.
In operation, when driving in the city,
bulb 6 only will be illuminated. The direct rays of light from the bulb in a. concentrated dazzling beam is prevented by the hood 7?. which shields the bulb from view. The horizontal partition prevents the powerful partof the beam from being reflected The particular type of reflector, lens or casing used is immaterial and, forms no I part of the present invention, applicant merely claiming the features as set forth in the following claim.
What I claim is:
In a headlight, a reflector, a source of light comprising an electric bulb at substantially the focal point thereof, a horizontal partition mounted in the reflector and below the lowest portion of the bulb, a hood on the partition to conceal the light source from the region above the partition and being in close proximity to the bulb at its top portion, and a second source of light secured in the reflector above the hood and in close proximity to the top thereof, whereby direct rays from the first bulb will be screened from all points in front of and substmt-ially below the horizontal and the two bulbs will be clustered substantially at the focal point of the reflector.
This specification signed this 15 day of March A. D. 1926.
