Application tiled. March 17, 1921. Serial N'o. 452,917.

To all 'whom zt may concern:

Be' it known that I, vFinition MCPEEK, a citizen of the UnitedStates and a resident of Sardis, in the county of Monroe and State of hio, have invented a new and Improved Headlight Dimmer, of which the followingwhich serve to confuse and to impair the.

vision of the driver of an approaching car.

A further object is to provide a dimmer, whichwill accentuate and increase the rays of light which are thrown on the road directly in front of a car so that a full road illumination is had without unnecessary glare. i y

A. still further object is to provide a dimmer, which may be uickly applied to various forms of headlights now on the market,

which will be Simp e and practical -in construction, strong and durable in use and coinparativel inexpensive to manufacture.

With t ese and other objects in view, the invention consists in certaln novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings Figure l is/a view. partly in side elevation, but mainly in vertical section through a headlight illustrating my improved dimmer in applied osition; f

Figure 2 1s a view in front elevation of the dimmer, the dimmer illustrated being intended for use on the right headlight of a car. Figure 3 is .an enlarged franentary view in vertical section therethroug Figure 4 is a view in vertical section illustrating a modified form of dimmer; and

`Figure 5 is a reduced view in front elevation similar to Figure'2 and showing a dimmer for use upon the left headlight of a car.

Referring in detail to the drawings, 1 represents a headlight casing, which supports the usual parabolic reiiector 2. The rellector 2 includes at its outer edge, an annular flange 3, overlying and resting against an annular internal shoulder 4. in the casing 1. A lens 5 is ordinarily clamped against the flange 3 headlight by a beaded frame such as 6, hingedly or otherwise connected to the headlight casing.

My improved dlmmer includes an outwardly presented annular lange 7 adapted to be clamped between the edge of the lens 5 and the flange 3. A ring of felt or other packlng material 8 is inter osed between the flange 7 and the edge o the'lens 5 to cushion the slight movement of the lens incidental to the vibration of the car.

A tapered ring 9 is integral with the flange 7 and serves to rlgidly support the ends of a vplurality of transversely disposed parallel metal strips 10. The strips 10 decliney appreclably from their rear to their forward edges and form in effect a screen or shutter to keep the glare of a headlight from the eyes of the drlvers of approachin cars.

-The under faces of t e strips 10 which are exposed to the rays of thelight from the are treated ywith a coating of highly dpolished light reflecting material 11, adapte to reect therays of light down on to the roadin front of the car; The outer upper surfaces of the strips 10 are treated with a coating of dull light absorbing material 12 to further dim the glare from the lights. The strips may either be painted to produce the desired light reflecting and absorbing surfaces, or .some reiecting or absorbing medium such as lass ofdiderent colors may be applied to t e strips, as indicated 1n Figure 3. A pair of strengthening ribs 13 attached to all of the strips prevent vibration of the strips.

The ends of the intermediate strips 10 may be painted either green or red, as indicated at 14 and 15 to represent the port and starboard running lights of ship.

InFlgure 4, I have illustrated aI slightly modified form of dimmer in which the forward edge of the ring 16 extends beyond the Aforward edges of thestrips 17 so that a lens 18 may be conveniently sup orted against the strips 17 with its outer ace lush with the flange 19. In this. instance, brackets or clips 20 are provided around the edges of the rie? 16 for retaining the lens in place.

arious slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the lnvention and hence I do not wish to limit m self to the precise details set forth, but s allconsider myself at liberty to make such slight changes and a1- including a tato be clampedhetween a headlightvcasing c and frame, said strips terminating short of l0 the `forward edge of ,the ring, and means re-y taining a lens in the ring against the strips and Hush With Said ange, said means comprising angular brackets arranged around the ring and engageable with a lens.
