EDWARD I. rEToW, or HYANNIS, MASSACHUSETTS, AssIGNoR or ONE-'RALF To NEW ENGLAND GLASS WORKS, OF PROVIDENCE, RHODE ISLAND, A PARTNERSHIP POSED OF ALBERT WEINER, ISAAC L. RICE, AND ALEXANDER ,WEINEBh NoNenARE STRUCTURE.

Application filed October 4, 1923. Serial No. 666,623.

To all whom t may concern.'

Be it known that I, EDWARD I. PEToW, a ycitizen of the United States, residing at Hyannis, in the county of Barnstable and State 6 of Massachusetts, have invented certain new and useful Improvements in Nonglare Structures; and I do declare the following to be a full, clear, and exact description ofD the invention, such as will enable others skilled in 10 the art to which it appertainsto make and use the same.

My invention relates to light transmitting bodies such as headlightlenses, glass or other transparent coverings for casings inclosing intense light that is injurious to the eyes, etc., and more particularly to a body or structure of this character which will prevent the injurious glare of such lights without di1ninishing the amount of light radiated from the bulb, burner, torch or the like and any re- Hector which may be associated therewith.

The principal object of my invention is to provide a simple, practical and highly effec-v tive non-glare structure of this character,

which may be used as a headlight lens or for various other purposes,

The above and other objects are accomplished as hereinafter described and in the accompanying drawing I have illustrated several forms of practicing the invention.

In the drawing Fi 1 is a face view of headlight lens embodymg the invention;

Fig. 2 is a vertical cross-sectional view;

` and y Figs. 3 and 4 are sectional views through modied forms.

I have discovered that a substance known usually as essence dorient or oriental pearl 40 essence when applied to a transparent support such as a sheet of glass or sheet of celluloid will cause intense and glaring rays of light when transmitted through such treated sheet to lose thel intense glare without diminishing the volume of light. While this. essence dorienhrlwhigh is made from scales of certain fish, has been used in the manufacture of articialpearls, it is my discovery that when applied to a transparent plate or sheet that the light transmitted through the same will be so subdued that the eyes will not be injured orblinded and at the same time there will be no loss of effectiveness of the light. My invention is,

therefore, particularly adapted for use in ,connection with headlight lenses or cover.

ings of automobiles and in the drawings I have illustrated in Figs. 1 and 2 the ordinary' circular headlight lens 1 consisting of a transparent glass plate having the coating 2 applied to one face of the same. This coating may be applied by dipping, spraying or otherwise andv one or more coats maybe employed. If desired, the coating or coatings may be applied to both faces of the trans-y parent sheet 1a as indicated at 2a in Fig. 3 or as shown in Fig. 4 the coating 2b may be in the form of a separate hn or sheet 2b arranged between two transparent sheets of glass, celluloid or the like 1b. Obviously, the coating lmay be applied directly, to one face of the glass sheet as in Fig. 2 and a backing.-

or cover sheet of glass may be placed against this coating as suggested in Fig. 4.

IVhile the essence dorient maybe applied to the transparent support in any suitable manner I prefer to apply it in the vehicle such as varnish, shellac, cotton laquer or the like and I preferably, but not necessarily, use the following proportions, that is, 10 cu. cm.

of essence dorient to 12 fluid oz. of suitable vehicle. As indicated above, one or more coats may be applied to obtain varying thicknesses for the coating, depending upon whether or not it is desired to reduce the volume oflight which will pass throu h the structure. However, I have foun that where a very thin coating is used there will be no loss of light when it passes through the Structure and that the blinding glare of an intense light will be entirely eliminated.

I claim:

transparent sheet andv a film associated 2. A non-glare structure comprising a 1. A non-glare structure comprising a' transparent support and a coating thereon comprising essence dorient and a vehicle.

3. A non-glare structure comprising a sheet of transparent material and a film associated therewith andl made from a compound consisting of a mixture of 10 cu. cm. of essence dorient and 12 fluid oz. of a ve'- hicle such. as cotton lacquer; f

In testimony kwhereof I have hereunto axed my signature.

EDWARD I. PETOW.
