Description

P. JOHNSON ET AL UNBREAKABLE ANTIGLARE LENS Filed Sept. 17. 1921 TOR i 4, v ATTORNEY WITNESS:
Patented Oct. 9, 1923.
UNITED- STATES.
PATENT OFFICE,
PETER JOHNSON AND GEORGE A. GRAY, OF ARLINGTON, NEW JERSEY.
UNBREAKABLE ANTIGLARE LENS.
Application filed September 17, 1921. Serial No. 501,268.
of Hudson and State of New Jersey, have invented new and useful Improvements in Unbreakable Antiglare Lenses, of which the following is a specification. I
This invention relates to improvements in antiglare lenses and one of the principal objects of the invention is to produce an unbreakable device of this nature.
Another object is to produce an anti-glare lens from a single sheet of celluloid and-having a pluralit of light baflles.
Another object is to produce a device of this nature which shall be simple of construction, cheap to manufacture and highly etiicieait for the purpose for which it is des1 e ith these and other objects in view which will be more apparent as the description proceeds the invention consists in certain novel construction and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims and are illustrated in the accompanying drawing in which Figured, is a front elevation of my improved unbreakable anti-glare lens.
Figure 2, is a vertical sectional view of the same.
Like characters of reference refer to like parts in both views.
Referring to the drawing in detail, 10 represents the body portion of the lens, the same being made of celluloid of uniform thickness and being frosted or otherwise negatively finished. Formed out fIOI'flothG surface of the member 10 are a plurality of curved hoods or shields 11, which are also frosted. Joining the lower edges of the elements 11,
with thebody portion 10, and arranged at a slight angle are elements 12 which are made from clear celluloid so as to permit the easy passage of the light from the source of illumination downwardly on to the road.
It will be seen in this manner we have produced an anti-glare lens for automobile and other headlights which is practically unbreakable and which effectually prevents direct projection of a heavy beam of light and which through the angular clear elements 12 further causes the light to be directed downwardly and forwardly on to the road where it is needed,
lVhile we have described what We deem to be the most desirable embodiment of our invention, it is obvious that the details may be changed without departing from the spirit of our invention and we therefore do not limit ourselves to the precise details of embodiment described and illustrated but may resort to such changes as lie within the province of a skilled mechanic and the range of equivalency.
What is claimed is:-
1. As a new article of manufacture, an anti glare lens formed of a single piece of frosted celluloid and comprising a body portion," and hoods integral therewith, said hoods having angularly disposed clear base elements.
2. A lens formed of frosted celluloid having superposed hoods projecting from one face thereof and arranged in parallel relation with respect to each other and each provided with a clear angularly disposed portion at its bottom integral with the body of the lens.
. In testimony whereof we have affixed our signatures.
PETER JOHNSON. GEORGE GRAY.
