ATTORNEY WITN E55:
Patented oer, e1, 1922..
@NHTED STATEJ FATENT @FFHCZEO LENS.
Application filed June 13,
To all whom it may con'cern Be it known that I, ONIG ASLANIAN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Lenses, of which the following is a specification.
This invention relates to lenses for the headlights of automobiles and has for its object the provision of a lens of novel construc tion whereby to eliminate the glare which is such a constant source of'danger along the highways.
An important and more specific object is the provision of a lens which is formed entirely of glass and which includes an upper hood portion of a translucent nature and preferably colored and which further includes a lower frosted portion, this lower portion being stepped with the steps inclined.
An additional object is the provision of a lens of this character which will be simple and inexpensive in manufacture, highly efficient, and a general improvement in the art.
With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which- Figure 1 is a front elevation of my lens, and
Figure '2 is a vertical sectional View therethrough.
Referring more particularly to the drawings, I have shown my lens as of. circular form and formed entirely of glass pressed to define an upper hood portion 10 which is a section of a sphere and which is made translucent and preferably colored a light blue, though any other restful non-glaring color, such as green mi ht be just as well employed. From the lbwer edge of the shield portion 10 extends a downwardly and rearwardly inclined portion 11 which has 1921. Serial No. 477,229.
its rear edge terminating short of the plane of the back of the lens and leading from this rear edge is a downwardly and rearwardly double stepped portion 12. The portion 11 and the double stepped portion 12 are frosted.
In the use of the lens it will be seen that the upwardly radiating rays of light will be either absorbed by the shield 10 or be reflected thereby downwardly back onto the reflector of the lamp, not shown, and these rays will subsequently pass out through the portions 11 and 12. Owing to the frosting of the portions 11 and 12 it will be quite apparent that there will be no possibility of glare.
From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and consequently inexpensive headlight lens which will efiioiently operate to eliminate glare and consequently render night driving safe in so far as headlights are concerned.
While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.
Having thus described my invention, ll claim:
A headlight lens of circular shape designed to cover the entire front of a head lamp, formed as a glass shell having substantially its upper half of outwardly extending spherical formation and of a translucent nature and colored, the remainder of the shellbeing of step like angular formation and frosted and uncolored whereby to produce a diffused glow upon the road way.
In testimony whereof ll afiix my slgnature.
ONI G ASLANIAN.
