Description

NONGLARE HEADLIGHT LENS Filed Jan. lO, 1934 hammam, aies:
UNITED STATES PATENT OFFICE musei sonoma naanuonr ums Geom n. smith, um amen. N. J. Application January 10, 1934, Serial No. 708,115 1 cwm. (ci 24o- 41.0
The present invention relates to certain new and useful improvements in lenses and consists in the provision of an improved lens for head lights.
An object of the invention is to provide a lens especially adapted for use'with the headlights of motor driven vehicles which will effectively prevent glare.
v The invention together with its objects and advantages will be best understood from a study ci the following description taken in connection with the accompanying drawing wherein:
lllgure 1 is a plan view of the lens with certain parts broken away and shown in section, and
Figures 2 and 3 are detail sectional views taken substantially on the lines 2--2 and 3 3 respectively of Figure 1.
Referring to the drawing by reference numerals it will be seen that my improved headlight lens comprises a disk Ylike body 5 that in its centeris provided with an integral circular hollow portion or chamber 6 the walls 7 of which project beyond the plane of the disk 5 and are convexed on their outer surfaces and concaved on their inner surfaces. The chamber 6 is adapted to contain a suitable fluid and on the rear side of the lens the part 7 thereof is integral with a narrow elongated radial extension 8 ilorm-A ing with the adjacent part of the lens 5 a lilling neck or passage 9 through which the fluid is introduced into the chamber 6. A plug or the like 10 sealsthe neck9 asclearlyshown inFigures 1 and 3. A
same, glare from the headlight will be greatly u diminished if not totally eliminated.
It will be further apparent that a lens of this character may be economically and cheaply made and can be used with headlights of general construction without any material altera- 05 tion in the construction of the head lamp casing.
Having thus described my invention, what I claim as new is:
A head lampmlens having horllqrgngwntral por- 70 tion defining amililhamber opposing `iv`1ls"f` which project beyond the plane of the lens and have convexed outer surfaces and concaved inner surfaces, and a narrow channel-shaped part formed on the inner face of the lens with its lower end formed with the upper portion of the inner wall of the chamber and its upper end terminating short f the upper portion of the lens, the channel of said member, with a portion of the rear face of the lens, forming a passage, the lower end of which communicates with the chamber and the upper end of which opens out through the upper end of the channel member, and a stopper for closing the upper end of said passage.
