which stifiens "the Central, portion" of the disc. Beck oftlieflope'ning 17 is laid a disc: 18, of ground glass; or ordinary glass ether wisef'treeted to rend r the shine translucent the disc. 18 be'1n'g retained in place by inteflgrz il bent lugs 19f'emhraei'ng the periphery IOU of [the disc 18. Any ether "suitable means forniolinting and seeuring the disc 18love: the o" purvi iv ofthe p v Betweenithe vertical ribs 16 1nd; between 7 the inetal ot the Ielined louvers or vanes-2Q, between Whiclrthe ning- 17.-s ybe-empldyed within the light a a and by'which they as deside peripheral portions of the disc are,

and forward direc- 16 and the opposite flected in a downward tion. Between the ribs formed in the same "manner two similar series of vanes or louvers 21. The described" 'manner of forming the vanes onlouvers creates atthe ends of the latter warpedor twisted portions 22 (Fig. 5) by which they are integrally joined to theribs 16,1the centralring l7, and the peripheral portion' 23 of the disc, which latter isbent to torm a mar inal flange b which the disc is clam ed and securely held between thevinner periphveryof the retainingringll and theilens 14-, I as clearly shown in F g. 3. These Lwar'ped end portions of the vanes have the full widtl'i ot the ,latterand provide much stronger end supports for the vanes than is obtainable by the practice heretofore employed of slitting the Inetal at the ends of the vanes tor nearly the full width of the latter and then bending the vanes to the required inclina-' tion..- 'q

The sheet metal disc having thestructure described; is capable of being cutand 'bent ot the ring 1 vehicles.

into the describedftorm by one or two die press operations, and th'ecentral d1soj18 is ,asily and quickly applied by centering-lit behind the opening 17 against the rearsi'de T and then bending the clips 19 overits periphery. V y

lVith further reference to the louvers or vanes 20 and'21,'it will be observed by reference to Fig. 8 that the vanes in the upper half of the discare so formed as tovhave a slightly, greater downward inclination than the vanes-in the lower half of the disc. This produces-a desirable distribution. and ditfusion of thel light rays along the roadway and prevents any o'tthe director reflected light rays from strik ng into the eyes of pedestrians ordrivers traveling in the 0p posite direction. The central {1180718136} mits the passage of sufficient hght to make head-lights. easily visible at a distance, but

dims and softens the light sufficiently to make it unob]ec t1onable andtre from any blinding effect to the ClI'lVQIS of pass ng I claimf V ln inanti glare comprising a concave-convex sheet metal disc having a series of transverse downwardly and forwardly inclined louvers and a central ring, and a flat disc oft-ranslucent material mounted in said ring. 7 7' s 2.
