To all whom it may concern.-

Be it known that LWILLIAM H. Mounnousn, a citizen of the United States, re siding at Pasadena, in the .county of Los,

Angeles and State of California, have invented new and useful Improvements in Light-Ray Regulators, of which the followin is a specification. l

J his invention lator.

It. is the principal object of this invention to provide a device which may be readily interposed between the source of light and lens within automobile headlights and which will bend the light rays in a manner to prevent them from roducing a glare and at the same time irecting them upon the roadway to produce a maximum amount of illumination without materially dimming the light. Other objects will appear hereinafter. The invention is illustrated, by way of example, in the accompanying drawings in which:

Figure 1 is a view in vertical section as seen through a headlight and particularly discloses the manner in which the ray regulator is mounted.-

Fig. 2 is a view in front elevation illustrating the lamp with its lens removed and the ray regulator in position.

Fig. 3 is a view in perspective illustrating one of the deflecting vanes as viewed relates to a light ray regu- 'from above.

Fig. 4 is a view similar to Fig. 3 illustrating one of the deflecting vanes as viewed from below.

Referring more particularly to the drawin 10 indicates the outer case'of a headlig t within which is mounted a parabolic reflector 11. A lens frame 12 is securedover the front of the case and the reflector and supports a lens glass 13. Mountedat the rear. of the reflector is an incandescent lamp 14 which is positioned within a socket 15 held by the case 10 and throu h which it extends. It will be understood t at the design of the lamp is not essential to the present invention but that the ray regulator '16 is adapted to be operatively mounted upon headlights of various types.

The ray regulator as here shown is formed of a series of equally-spaced horizontallydisposed deflecting vanes 17 which are su- Speclflcation 01 Letters Patent. Application filed September 24, 1917. Serial No. 192,925.

periinposedone above the other and are mounted upon rods 18 and 19. These rods extend substantially vertical, being slightly Patented Aug. 6, 1918.

inclined t'oward each other as they approach a mounting plate 20 at the top of the regulator. This plate has an arcuate outer face which conforms to the lens frame 12 within which it is held. The lower ends of the rods 18 and 19 are secured to the lowermostvane of the regulator. This vane in turn is secured to a lower mounting plate 21 by means of bolts 22 and 23. This lower plate is angular in section and has a front arcuate portion conforming to the frame 12 in the same manner as the plate 20. Brace wires 24 and 25 extend downwardly through openings 26 and 27 in each vane. The vanes are so constructed that the metal punched from the perforations 26 and 27 will form tangsl28 which extend downwardly and space the vanes equal distances from each other. The

openings 29 at -the forward corners of the vanes through which the rods 18 and 19 pass may also be formed with tangs 28 for spacing purposes.

Reference being had to the drawings it will be seen that the vanes are all of di en cut lengths and that some of them vary as to width as well. The length of the vanes is graduated from the lower vane to the top vane in uniform order. The length of the lower vane is substantially the length of the cord of an are formed around the botin the lengths of the vanes is directly related to the curved surface of the reflector 11 so that the side rays thrown from the reflector may pass through the lens without obstruction or deflection. It is manifest that these tom of the lens frame 12. The graduation rays will not produce a glare if the headlight is properly set. 4 When considered in plan,

each of the vanes has ends which converge rearwardly to further prevent obstruction of the side rays of light. As shown inlig.

1, the vanes are substantially the same width 1 damaging to pass/from the reflector without. obstruction.

.minate a distance from'the top thereof, said distance being determinedby. the shape of the reflector to allow rays which are not In operation, the ray. regulator is mounted within the headlight as particularly shown in Fig.1 and is held by the lens'which is positioned thereover. When the lamp 14 is lighted, its front rayswill ass outwardlybetween the vanes 17 while til will. fall upon the curved surface of the ref 7 their upper and lower faces,

The light from the headlight along the central portlon of the light beam will passbetween the vanes vflected along a downward path of travel without glare. It will thus disclosed is decidedly simple in its construc tion, may be easily mountedwithin head be seen that'the device here lights of ordinary. design, and will act effectively to regulate the beam of light passing from the headlight.

While I have shown the preferred construction of my light ray regulator as now known to me, it will be understood that vation and arrangement of parts maybe made by. those skilled in the art without depart- --and .the reflector, comprising a series of equally'spaced horie remaining rays ing from the spirit of my invention as claimed. I

I claim: V

The combination ing a parabolic reflector, a lens in front of the reflector, and a light between the lens of alight ray regulator zontally disposed deflecting vanes mounted oneabove the other upon vertically extending rods, brace wires extending through the with a headlight havvanes, a lower mounting plate fixed in. pos1- tion behind the lens, bolts securing the lower vane to the lower mounting plate,'and an upper mounting plate secured in position behind the lens; the upper ends of the rods being attached to the upper mounting plate.

The cOmbination w1th a headlight hav- Y ing a parabolic secured in position behind the lower part of the lens, an upper mountingplate secured in position behind reflector, a lens infront of i the reflector, and a light between the lensand the reflector, of a lower mounting plate the upper, part of the lens, rods secured to the upper mounting plate and extending downwardlyand diverging, a series holes;. the punching's from the holes being turned toform spacingtangs and there being other holes through which the rods extend, so as tomount the vanes in horizontal positions equally spaced apart; brace wires inserted through .the holes from. which the of vanes having punched tangs arecut to hold the vanes together, and
