1 Claim.

My invention relates to glare shields for headlights.

The main object of the invention is to provide a shield which will absorb all glaring stray rays from a vehicle headlight without disturbing the focused rays properly directed by its reflector.

Other objects include the provision of economical means to support the shield so devised as to be readily attached to the headlight bulb.

Further objects will become apparent by perusal of the following description of the preferred embodiment of the invention shown in the accompanying drawing, in which,

Figure 1 is a view of a section of a headlight reflector with its socket and electric lamp therein, with one of the shields mounted on the latter;

Figure 2 is a front View of the shield as seen from the front of the light; and

Figure 3 is a cross-section of the light bulb and shield holder taken on line 3-3 of Figure 1. Identical numerals in the three iigures refer to similar parts.

As previously stated, the shield is used with a regular electric bulb 5 mounted in reflector 6 i5 andy consists of a disc 1; Disc I is sufficiently large in order to intercept any ray from the filament 8 which, in the ordinary way, could emerge from the headlight without coming in contact with the reflector. By not striking the reflector, these rays, without my shield, cannot be directed 'as rays S are and will stray and blind anyone within a large area beyond the focus of the light.

With my shield, however, these rays are not permitted to so stray out but are intercepted thereby.

A further stage of this invention deals with the manner in which these stray rays are intercepted. The disc is translucent so as t-o allow light to go through but governed so as to intercept white glaring rays. By the employment of green glass for the disc, green light, which is not glaring, will go through and serve to light, for instance, the sides of a road; in other words, be of some use without the disadvantage of uncontrolled stray rays.

45 The disc may either be of green glass or of white glass with a transparent coating, or again, a thin sheet of green gelatin may be placed between two plain glasses as desired, or as an alternative. noninflammable cellutone may be used 5 kas the coloured medium.

Disc I is held vertically and centrally of lamp 5 by means of a doubled wire support Il. The wireis looped at the rear of the disc, around a rivet I2, passing through a central aperture in (Cl. 24U-48.6)

the rein; the two strands are then bent rearwardly over the lamp and twisted together to a point just in line with the meeting point of the bulb with its base. From that point, as shown in Figure 3, the strands are separated and shaped to snugly encircle base I3 of the lamp, the lowerv ends terminating in the so-called safety pin clasp I4. A resilient washer I5 is interposed between the rivet and the wire as shown.

When attaching the shield, the ends free, the base is straddled and the former hooked together. The reverse will quickly allow the shield to be removed when required to change a lamp.

While I have described my invention strictly in connection with the embodiment shown, it 15 must be understood that changes may be made to suit varying circumstances falling within the spirit of the invention and scope of my claim.

What I claim is:

In a glare shield structure for a headlight of that type having a reilector and a lamp axially of the latter, said structure including an axially apertured translucent disc-like at shield adapted to be positioned forwardly of and having its aperture aligned with the axis of the lamp, said shield being so formed and arranged to make it j adaptable, without substantially impeding the light rays passing from the lamp to the reflector and to reduce intensity of those rays which emerge from the light without being reflected, a pair of resilient suspension arms for the shield having depending rear end portions adapted to be positioned intermediate their ends against and grip opposite sides of and extended from the lamp base, outwardly inclined intermediate por- W tions twisted together throughout adapted to be "a disposed lengthwise of and in spaced relation to the top of the lamp and depending straight front end portions adapted to be positioned at the front of the lamp in abutting relation with the rear of said disc, said rear end portions at their lower ends having inherent coacting parts for latching said arms to the lamp base, said front end portions having inherent coacting parts at their lower ends merging into each other providing a closed loop surrounding the inner end of the aperture in the disc, means extending through said aperture and loopfor securing the disc to said arms, said means being spaced from said lamp, and said shield having its front and rear faces free of inherent interruptions from said means to the outer edge thereof.

FRANK SCHUCH.
