-HE'ADLIGHT-DIMMEK Application filed. .Tune 26, 1918. Serial No. 242,025.

To all whom, t 'may concern Be it known that I, PAUL P. HEIN, a 'citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the .county and State of New York, have invented a new and Improved Headlight-Dimmer, ofnwhich the following is a` full, clear, and exact description.

This invention relates 'to headlights such as are 'commonly used on road vehicles, and has particular reference to means to nullify the objectionable glare that commonly accompanies a powerful lamp of this character.l .1

Among the peculiar objects of this Vinvention is to provide a device with means for carrying it' in substantially vertical position sufficiently far in frontl of the lamp structure or lens as to provide for an appreciable amount of laterally and rearwardly projected light for illumination of the roadway at the sides of the vehicle and also to illuminate the vehicle itself, enabling thereby any person located at a distance in front of the vehicle to readily recognize or discern the nature of the vehicle or to read the license number thereon.

Another object'of the invention is to provide an attachment for a standard lamp, the same constituting a device adaptedto be readily applied to any existing headlight, and yet being possessed of qualifications to meet the demands of the law or municipal vregulations regarding the intensity of the li ht from the lamp within the structure.

lith the foregoing and other objects in View the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a prac- Y tical embodiment thereof reference is had to the' accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical central section of a standard headlight equipped with my improvement, the sectional part of the view being substantiallyA on the line 1-1 of..

or reflecting clear surface.

therethrough. This frame Fig. .4' is a horizontal sectional detail on the line 4 4 ofFig. 2.

The laws and ordnance's of various cities or municipalities requiring ysome means to nullifyor reduce the offensive glare of headlights whereby pedestrians or others who may be positioned in fron-t of an" approachleast seriouslyconfused, I provide a means either as a part of an automobile lamp or as Specification of Letters Patent.' Patented' Julyls, I'

. ing automobile are practically blinded or at l an attachment tobe applied to a l'standard l lamp casing whereby the glare from the lamp bulbv is either nullilied or reduced to such an extent as to be unobjectionable and yet suicient light is of the vehicle vand laterally thereof to meet all requirementsin practice.

eferring now more. specifically to the drawings I show at 10 a shield made of any suitable. sheet material preferably of a trans` lucent nature, suchv as white or tinted celluloid or the like, but .having a white bright This shield as indicated best in Fig. 2 is in the nature of a circular segment preferably just a little larger than a semi-circle and having a radius somewhat greater than thatof the lens or window 11 ahead of and spaced from which the shield is adapted to be supported. The shield may lamp window or lens 11 by any suitable means providing for free space between the lens and the shield for the purpose ofv dispersing the light laterally so-as to illumiin Fig. 3 as comprising a crown 13 in the projected both ahead nature of a flat ring adapted to be gripped f between the periphery of the lens 11 and the outer lamp casing ange 14 where it will be held in reliable position. This frame includes also 'a series of

legs

15 and 16 each having a foot 17 .bent at right angles to the tapped hole 17 leg and each foot having a 12 1s shown as being formed by cutting or stamping from a single pieceof sheet metal, the legs being bent forward at right angles to the plane of the ring 13 andso may project forward parallel to one another ahead of the main port-ion of the lamp. The feet 17 are bent outward from the axis of the device. The side leg 16 as indicated plainly in'Fig. 1 is shorter than the other two legs so that the side portion of the shield secured lthereto is inclined somewhat rearward toward the lamp casing and thereby two important advantages are realized, as follows: Flrst, the

' the provision of the curved edge portion to project s as to connect and also by the fact that the edge portion projects materially beyond the scope of the lamp lens. -The 'shield is provided with holes registering with the holes 17 screws 18 or similar fasteners are adapted the shield to the frame.

Each of the lamps or headlights equipped with one of my improvements has the circular portion of the shield on the left side so as to obstruct the direct rays of the light from the View of any person approaching on the road and whom the driver of the vehicle having the lamp will meet and pass by turning to the right. The upper portion of the shield has an extension over toward the. right side of the lamp to obstruct somewhat more of the light emergmg from v ever, adjacent the top of the reflector.

to the axis of the lamp is preferably vertical as shown at 10a and lies just the right'side of the edge 10 there is ob- Alight to pass directly in which hat portion, ho-wf to the right of the lamp lament; Atv

servedsuflicient space unobstructed to permitI sufficient light from the reiector to ilvluminate the-roadway ahead, while al considerable portion of the light striking against the rear reflecting surface of thev shield will be spread out laterally and rearwardly so that hicle will be able -to see clearly the nature of-the vehicle and plainly .and easily read the license number on the front of the machine. The nature of the shield itself should be such as to permit a soft diffused therethrough and still prevent an possible glare from the lamp filament. he shield as indicated covers all of the filament and a large portion of the reflector. By no reasonable possibility therefore can any person on the road see the lamp or lamp bulb directly.

A device made in accordance with this in vention is not only cheap to construct, but

may be easily applied to any standard'lamp casing and serves the purpose with a high degree ofefficiency. v

I claim: In a dimmer for headlights, the combination of a translucent glare reducingcshield .in the form o f a segment of a circular disk,
