Fig. 3 is a fragmentaryiview toill'ustrate details Vof structure to be yhereinafter de-- sciibedf l In' Fig. :2 of the drawings, I Vhave shown just enough of the headlight structure to Villustrate the application. of the invention thereto. In'said figure, l indicates the outer casing or shell 'of the lamp,' 2the parabolic :reflector therein, and 3 the'ring for clamping the headlight glass or lenses in place.
The device of my invention comprises two relatively thin translucent discs 5, GLY These discs may be made of paper or other translucent inateri al which willV transmit light Saidl discs are provided with a plurality of holesor apertures 7, S distributed over the saine and arranged withthe holes?- in(4 one disc staggeredor'otlset l'roni'the holesV `8 in the other disc7 so that'the holes inthe r respective discs will be covered by the iinpertorate portions of the other disc when the discs are placed one against the other, as shown in Figs. 2 and 23.' By this arrange; ment, there isonly one layer of' disc material covering' the holes andV two layers 'ot disc material elsewhere. This allows more lightv tov pass Atlir'ouliifh the discs atv the holesthan elsewhere anch as these holes are relatively smalland are distributed over the entire area-of the discs in a regular or uni- Jorm maiinei",'the glare will be eliminated withont appreciably dimmi-ngor diiniiiislo` 2i, 1925. serial' ne. irons".

ln thedrawings, the holes 7, 8 are laid ont certain `corners of the squares.
I claim as my'invention: 'y l n I`l. An anti-glare device for headlights, comprising two relatively th'imilat discs ot on aj square formation with Vthe holes` at f translucent material, said discs being placed one'fagainst the other and being substantially equal jin size so fas to be coextensive, oneA ot said discs having apluralityv ot holesv `distributed `over the same and coveredrby the imperforate'portion of the other `disc.
