UNTTD STATES PATENT OFFICE.
HEADLIGHT LENS.
Application filed may 14, 1925. Serial, No. 30,287.
Toyzll. whom it may concern:
Be it known that I, GEORGE EUSTIS Convenien a citizen of the United States, and a resident of Washington, District of Columbia, have invented a new and Improved Headlight Lens, of which the fol-' With my improved lens I provide a clear spot or section at the upper portion of the lens and break up or diffuse the rays which are deflected from the lower portion of the lens, and I accomplish this improved result by an improved construction and arrangement of crossed translucent bands which cover approximately three-quarters of the lens, leaving approximately one-quarter of the lens transparent and clear, and I provide this clear or transparent portion of the lens at the upper portion thereof, extending to a point in alinement with the center of the light or bulb.
A further object is to provide a lens which will fully comply with the legal requirements and regulations, which can be manufactured and sold at a reasonably low price, and which will most efficiently perform the functions for which it is intended.
W'ith these and other objects in View, the invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claim. v I
In the accompanying drawings Figure 1 is a view in front elevation, illustrating'my improved lens in operative position in a headlight;
Figure 2 is a very much exaggerated fragmentary view in section on the line I alterations might be made in the general 22 of Figure 1. v
1 represents a headlight which may be of any ordinary construction, which is provided centrally with an electric lamp 2. 3 is my improved lens which is located in the front of the headlight casing 1 and which may be made of any diameter and thickness of material desired.
This lens 3 is of clear glass and is provided on either its front or rear face with crossed bands 4. These bands 4 are etched into the surface of the lens, and, this etching process renders the portions of the lens covered bythe bands translucent, with the portion between the bands left transparent.
I would call particular attention to the fact that these crossed bands are provided throughout the lower portion of the lens and throughout the side portions of the lens but they do not extend over the upper portion of the lens. In other words, I leave a section of lens, indicated by the reference character 5, at the upper central portion of the lens which is clear, and this section 5 is approximately one-quarter of the entire lens.
The clear portion 5 is of somewhat inverted triangular shape with the apex of the triangle located centrally of the lens and in line with the axis of the headlight and also of the electric lamp 2.
T, of course, do not wish to be limited to the exact proportion of clear section of lens. but I have found that good results are had by making onequarter of the lens, and that the upper portion, clear, while the other surface of the lens is covered by crossed translucent bands, preferably. etched into the surface, as above described.
By reason of this construction the light rays which are deflected from the upper portion of the headlight reflector are. thrown downwardly on the road through the transparent portion 5 and are clear and of full volume and force, while the rays which are deflected from the sides and lower portion of the headlight reflector are directed through that portion of lens which is covered by the crossed translucent bands, and such light is diffused without any appreciable loss. of illumination.
While I have illustrated a specific form, it is obvious that various slight changes and form of the parts described, and hence I do not limit myself to the recise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fallwithin the spirit and scope of the a pended claim.
I c aim:
at headlight len mp sed of clear plane glass, having on at face and throughout approximately three-quarters of the surface of the lens parallel crossed bands separated from each other, leaving clear and non-difiusing areas between them, said bends being translucent and formed by etching, the other portion of the lens being clear and located at the upper portion of the lens and extending from the center of the lens to the periphery thereof and in 10 creasing in Width from the center of the lens to the periphery thereof.
