,ANTIGLARE DEVICE.

Applcationled September 19, 1925.

T 0 all whom t may con-cern.:

Be it known that I, IVILLIAM S. ALLEN, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, vhave invented certain new and useful Improvements in Ant-iglare Devices, of which the following is a specification.

My said invention'relates to an automobile headlight anti-glare device and it is 'an object of the inventionto provide a device of this character which may be easily attached, of simple and durable construction, and inexpensive to manufacture.

Referring to the` accompanying drawings which are made a part hereofand on which similar reference characters indicate similar parts,

Figure 1 is a vertical longitudinal section of a headlight having my inventionapplied thereto, A

Figure l2, a rear elevation of the invention as it appears when applied,

Figure 3, a detail view of a metallic fastener,

Figure 4, a view similar to Figure 2 of a modifie-d form, of the invention, and

rFiguref'), a vertical sefction of the modified form shown in Figure 4. Y f

In the drawings I have shown a headlight consisting of a light 10 and a reiiector 11. A lens 12 is also supported in any desired manner at the front of the reiiector 11. The foregoing structure4 is common in automobile headlights and forms no part of my invention.

My invention comprises a device adapted to be used in conjunction with a light of the above character to afford a distinct improvement in appearance and to soften, tone, or obscure the glaring or very bright light without sacrificing itsV effectiveness. A disk 13 of'celluloid or other material preferably colored is folded through its diameter to an acute angle and the said disk is placed behind the lens 12 and closely adjacent thereto. The disk is positioned on the lens so that the center of the arc of the disk or the locus of points of the radii is disposed at thecenter of the lens and the disk is above the horizontal diameter of the lens so that the straight or forward rays of light will pass in a substantially horizontal plane underneath the disk and illuminate the roadway while the bright rays, which would normally Serial No. 57,435.

blind the eyes of a motorist approaching in the opposite direction, "will strike the rearinclin-ed surface of the wing of the disk nearest the light and be reflected backupon the reflector 11 and thence in a horizontal direction along the roadway. The angular portions of the disk are held in fixed relation by means of' a metal clip 14 having pointedend portions 15 which are stuck through small slots in the disk and Vbent down to hold them in fixed relation. The disk is supported `on the lens 12 by means of spring fasteners or cross wires 16 and 17 secure-d by hooks 18 or other fasteners over the edge of the'lens. The vertically disposed spring fastener 16 extends through a` small opening in the center of the disk and through a similar opening 19V in the clip 14. The fasteners 16 and 17 are also provided with coiled portions 2O and 21, respectively. The coiled portion 2O is below and serves as a support for the disk 13 while the coiled portion 21 Yis disposed along the fold of the disk. Such arrangement permits only a very slight lateral movement of the disk due to the spring action as well as only a slight downward movement against the upper end of the spring' 20. The horizontally disposed spring vfastener 17 is disposed in the lbase of the angley between the folds of the disk and holds the disk against'thelens, the two spring fasteners disposed in crossed relation completely maintaining the disk in position.

If desired, the horizontal wire or support 17 `may be omitted and the structure shown Y in Figures 4 and 5 used instead. In this form of the invention a. vertical wire or support 22 is provided with the usual attachments or clamps 18 for the lens and the spring portion 23 is disposed between the wings and between themetal fastener or clip 14 and the opening in the center of the disk. Such structure will cause the disk to be maintained in proper position on account of the engagement of the metal fastener 14 with the upper end of the spring portion 23 and the opening through the center of the disk will permit tensioning of the spring downward through the opening. This will greatly simplify the attachment and reduce the cost of manufacture.

In operation only the very bright rays of light will be intercepted, theI less brilliant side rays passing out uninterrupted around the disk 13 and the bright rays will 'be softened as they j iass through the disk and some of the light will be reflected back upon the reflector and thence on a sulr=tantially horizontal line ahead on the roadway.

It will be obvious to those skilled in the art that many changes ma)T be made in my device without departing` from the spirit of the invention, and therefore l do not limit myself to what is shown in the. drawings and described in the specification but only as indicated in the appended claims.

Having thus fullv described in v said invention, what lf claim as new and desire to secure by Letters Patent is:

i. An anti-glare device for headlights comprising a colored translucent disk of thin material folded along its diameter rear* 'ardlv upon itself and adapted to be supported adjacent the central portion of the lens of the headlight in inverted position with one wing of the disk substantially parallel to the lens and the other wing extending at an angle thereto, and means for sup porting said disk, substantially as set forth.
