.AUTOMOBILE HEADLIGHT.
Application filed January-14, 1922. SeriaPNo. 529,176.
To all whom z'tmay, concern.
Be it known that I, GEORGE A. ROBERTS, a citizen of the United States, and a resident of Manchester Center, in the .county '5 of Bennington and State of Vermont, have invented certain new and useful Improvements in Automobile Headlights, of which i v the followingds a specification.
My present invention relates generally to 4' 1 0 automobile headlights and more particular-.
25 taken centrally therethrou Referring now to these figures my im-,
ly to non-glare headlights, my object being the provision 'ofa headlight construction whereby maximum light may be thrown upon a roadway in advance of the headlight,
without glare,'and still permit of the use of a clear glass bulb as well as a clear lass front late in .orderthat maximum vight from t e bulb will be utilized.
.In the accompanying rawing which il-.
lust'rates my present inv ntion and forms a part of thisspe'cification,
Figure 1 is a front elevation of my improved headlight, and I Figure 2 is a vertical longitudinal section roved headlight may include the usual casmg 10 and rim 11, the lattersurrounding the open front or forward edge of the headlight casing 10 and suitablysecured thereto for the purpose of holding the clear glass front plate 12 in place across the open front of the reflector 13 located withinthe casing. I
In the reflector 13 a source of light, for instance an electric bulb 14 is focused as usual, and this bulb maybe of clear glass;
its upwardly directed rays, which would otherwise impinge upon and be reflected fonwardly'by, the upperportion of the reflector 13, being subdued and its direct forward rays being cut off by means which I 1 will now proceed to describe.
In accordance with my invention a horizontally disposed partition 15 is located within the reflector slightly above the plane of the light bulb. 14 and includes a narrow surrounding .frame 16 whose forward portion extends across the front of the reflector immediately in the rear of the trans-.
parent front plate 12, said ame extending for the' full depth of the re ector and having aflat section of translucentLmaterial as at 17 disposed therein. This section of translucent material is preferably colored to soften the light, as by giving it a greenish hue.
Below the forward portion of thepartiti n- 15 is a vertical series of relatively,
narrow light deflecting fins 18, this series of fins extending vertically throughout the lower portion of the reflector 13 that is below the partition 15, and each fin being inclined upwardly and inwardlyso that all direct rays from the light source 14 as well as all rays reflected forwardly from that portion of the reflector 13 below the partition 15, will be deflected downwardly by the fins 18 and thus directed downwardly upon 'a roadway-surface in front; of the headlight. 4 v
It is obvious from the foregoing that imdimmed light rays emanating from the 1. A headlight including a source of light,
a reflector in which the source of light is focused havingan internal horizontally dis- ,posed translucent-partition above the source" of light and extending for the full depth of the reflector, and ab-series of vertically spaced light deflecting fins extending across theforward portion of the reflector below the said partition. 3
headlight will flood a roadway surface in front of the headlight without danger of 2. A headlight including a source of light,.
a reflector in which the saidsource oflight is focused, having an internal horizontally disposed translucent partition above the source of light and a vertical series of upwardly and inwardly inclined light deflecting fins in the forward portion of the reflector, the said series extending continuous! fly from-the forward prtion of the said partition to the, lower portion of thereflcotor as described.
