HEADLIGHT RECTIFIER.

Application filed September 24, 1923. Serial No. 664,521.

i To all whom it may concern.

Be it known that I, FRANK J. SOHISLER, a citizen of the United States, residing at Winthrop, in the county of Sibley and State of Minnesota, have invented certain new and useful Improvements in Headlight Rectifiers; and I do declare the. following to be a full, clear, and exact description of the in- 'vention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention aims to provide a simple and inexpensive, yet an exceptionally effec tive device to prevent blinding glare from, automobile or other headlights, above a predetermined plane, while permitting unob structed projection of light rays below such plane.

A further object is to provide a device which will shield substantially the lower half of the headlight reflector and the upper portion of the bulb, the bulb shieldbeing so mounted as to be movable aside whenchanging bulbs.

With the foregoing in View, my invention resides in the novel subject matter hereinafter described and claimed, the descrip tion being supplemented by the accompanying drawings. I

Figure 1 is a front elevation of an auto: mobile headlight equipped with my invention.

Figure 2 is a vertical sectional view as indicated by line 22 of Fig. 1. V

Figure 3 is a horizontal sectional view taken substantially on line 33 of Fig. 1.

Figure 1 is a detail sectional view showing a slightly different form of construe tion.

Figure 5 is a horizontal sectional view on approximately the plane of line 55 of Fig. 4.

In the drawings above briefly described, the numeral 1 designates a well-known form of automobile headlight, said headlight.

' having a detachable rim 2 carrying a lens 3 which, due to the present invention, may be of plain clear glass. The headlight is provided with the usual parabolic reflector 1., bulb socket 5, and bulb 6.

Covering substantially the lower half of the reflector 4, is a non-reflecting cover 7 whose lower edge is held in place by the lens 3 or some part associated therewith, while the upper edge of said reflector is provided witha central seat 8 for the bulb socket 5. On opposite sides of'the seat 8,. the upper edge of'thecover-Tis preferablybowed upwardly as indicated at 9, with the end portionsof said edge declining from the bows. The front face of the cover 7 is preferably painted black although it could otherwise be treated to produce anon-reflecting surface and it has been found that by constructing this cover in the manner shown, no blinding rays of light will be projected from the light reflector, above a predetermined plane. Below this plane, however,

the r'eflected rays areprojected uninterrupt-' edly to adequately illuminate the. highway.

I preferably associate a bulb shield with the cover 7 In the present showing, a pair of bendable arms 10 are secured by rivets or thelike 11 to the cover'7, at opposite sides of the seat 8, said arms curving downwardly and then upwardly to extend under the bulb 6 and to straddlethe usual tip 12 of the latter- The upturned ends of these arms 10 are connected by an arched bulb. shield 13 whichis preferably integral therewith and is intended to lie in close proximityto the upper front portion of the bulb 6, over its tip 12. This shield prevents the projection of blinding rays directly from the bulb, and the inner side of said shield, as well as the inner sides of the arms 10, preferably have reflecting surfaces, to direct the rays of light backwardly against the uncovered portion of the reflector. Attention may here be directed to the fact that the arms 10 are bendable, permitting the shield 3 to be adapted todifferent sizeheadlight bulbs as well as permitting said shield to be moved aside when one bulb is being'removed and another inserted. V r

The construction above described is common toboth forms of the invention which have been illustrated. In addition to these features of construction, the device. shown in Figs. d and 5, is provided with a yoke 1 1 which is preferably integral with the cover 7, said yoke being adapted to extend over the bulb socket 5, and to be bent down upon the latter to frictionally anchor the rear end of said cover.

By providing the construction shown and described or a substantial equivalentthereof, a device is provided which may be easily and inexpensively manufactured from sheet'metal, yet regardless of simplicity, the deviceis highly ellicient and desirable. As excellent resultshave been obtained from the details disclosed, they-'may well be followed, but within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

1. A headlight rectifier comprising a non reflecting cover for substantially the lower half of a headlight reflector, a pair of arms extending forwardly from the upper edge of said cover-for disposition under the head-- 7 bulb, the front; ends of said arms being curved upwardly for location at the lower front portion of the bulb, and a shield extending between and carried by the upturned ends of said arms to shield the up per front portion of the bulb.

2. A structure as specified in claim 1; said arms and shield having reflecting surfaces at their inner sides.

In testimony whereof I have hereunto af- 20
