flllomey Patented Feb. 7, 1933 TES CHARLES A. KUHNS, OF NIAGARAFALLS, NEW YORK Application filed March 4, 1932. Serial 1T0. 596,818.

This invention relates to reflectors, and

in accordance with the present invention a reflector is provided that is especially adapted but not necessarily restricted for use in connection with automobile headlights.

The reflector according to the present invention is adjustable toward and away from the electric lamp or bulb and to any angle of inclination as found desirable.

The invention together with its numerous objects and advantages will be best understood from a study of the following description, taken in connection with the accompanying drawing wherein:

Figure 1. is a front elevational View of a conventional automobile headlight, a portion ofthe lens being broken away to show the arrangement of the reflector in the headlight casing.

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1.

Figure 3 is a sectional view through the reflector per se.

Figure'4 is a sectional elevational view through a longitudinally adjustable pivoted supportmember.

Referring more in detail to the drawing 8 it will be seen that 5 designates generally the casing of a conventional automobile headlight, and 6 the. lens. Suitably mounted within the casing is the conventional electric lamp or bulb 7. p v

The improved reflector designated by the reference character 8 is substantially cupshaped so as to fit over the forward portion of the bulb 7 and the concave or inner side of the reflector is 'nickeled or otherwise, treated to provide an efiicient reflecting surface.

The reflector 8 is provided with an attaching bracket 9 which in the present in-- stance is formed from a single length of wire bent and shaped to a substantial V with the sides of the V at the open end thereof welded or otherwise secured to the outer side of the reflector 8 at diametrically opposite sides of the reflector. At the apex of the V, the bracket 9 is bent inwardly into the shape of a U to provide a pair of opposed spring jaws 10.

A base plate 11 is suitably secured to the 7 bottom of the casing 5 inwardly thereof and adjacent the forwardend of the casing, The

plate 11 has ears 12 extending upwardly therefrom and the ears12 support therebetween a hinge pin 13. Asubstantially fork 'shapedmember comprises a sleeve like or tubular shank 14 that is internally threaded,

and merges at oneend into a pair of'relatively spaced prongs or extensions 15 which adjacent their free ends are suitably apertured and through said apertures extends the pivot pin 13. v w A Ashank' 16-has a threaded end portion screwed into the sleeve 14 and a flattened end 7 portion 17 that is adapted to be inserted into I the U provided at the apex of the bracket 9 and gripped on relatively opposite sides by the spring aws 10 whereby the bracket is portionof the hinge pin 13, and one end 18a of the] spring engages an adjacent car 12 while thebther ,end ofthe spring engages the extensions 15 and normally urges said'extension and associated parts'to rotatein a clockwise direction whereby the reflector 8 is yieldably retained in engagement with vthe lamp bulb 7. i A

From the foregoing it is apparent that by reason'of threaded engagement of shank 16 and sleeve 14, these parts may be readily ad justed as may be required by the size of the headlight with which the reflector is used.

In actual practice, it will be found that with a reflector of this character used in conjunction with a headlight, the light will be directed downwardly and over a material area of the road enabling the driver of the vehicle to have a clear vision, and such a reflector will be found especially useful when driving in a fog. Further, byuse of the reflector, glare is, if not actually obviated, reduced to a minimum thus obviating the necessity of dimming the lights when a car approaches from an opposite'direction.

Even though I have herein shown and described the preferred embodiment of the invention, it is to be understood that the same is susceptible to further changes in the construction, combination and arrangement of parts and accordingly I claim all such forms of the invention to which I am entitled in view of the requirements of the prior art and scope of the appended claims.

Having thus described my invention, what I claim as new is:

1. In a headlight, in combination, a casing, a lamp mounted in said casing, an auxiliary reflect-or engaging said lamp and having its axis disposed at an angle to the axis of said lamp, and means for yieldablyretaining said auxiliary reflector in engagement with said lamp; said means comprising a bracket fixedly secured within said casing, a fork hav ing the legs thereof pivotally engaged with the bracket, spring means engaging said bracket and fork and normally urging the latter to rotate in one direction, said fork also having a shank provided with a threaded opening therethrough, a rod having an end screw threadedly engaged with the shank of said fork and having its other end flattened, and spring arms secured at one end to said auxiliary reflector and having remote from said auxiliary reflector parallel portions frictionally engaging therebetween the flattened end of said shank.

2. An anti-glare device for vehicle headlights comprising a concavo-convex auxiliary reflector adapted to engage the lamp of the headlight with its axis arranged at an angle to the axis of said lamp, and supporting means for said auxiliary reflector yieldably urging said reflector into engagement with said lamp, said supporting means including a bracket adapted to be attached to the usual headlight reflector, a longitudinally extensible supporting member pivotally connected at one end to said bracket, and having at its other end a flattened portion, and a V-shaped bracket having sides secured to the auxiliary reflector at the open end of the V and at the apex of the V merging into clamping jaws frictionally engaging the flattened end of said supporting member.

In testimony whereof I aflix my signature.

CHARLES A. KUHNS.
