W. H. BURTIS GLARE DEFLECTOR Patented Feb. 21, 1928.
PA T E NT DEF-l CE...
Vide 2L,gl lieudeflector ,particularly. intended.
.and adapted for use in connection with auto mobile headlights, 1 which deflector .is in: the
form Qfiaihood.,projecting forwardly and. thenmwa i ly reduced in width .at, its extazemecend, whichNstandsdireetly in. front v\oifii'zlie center .of .the.lamp,,.for thus cutting off glaring-rays, which would :otherwise .be directedftotheleft and. forwardly, and directing the vlight?toward .the: right.
With these and other objects in view, my invention consists in the construction, ar rangement and, combination 'of the various parts of my glare deflector, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:
Figure 1 shows a front elevation of a lamp equipped with a glare deflector embodying my invention.
Figure 2 is a side elevation of the same.
Figure 3 is a detail, sectional view taken on the line 33 of Figure 1.
Figure 4 is an enlarged, detail, sectional view taken on the line 44 of Figure 1.
Figure 5 is a detail, sectional view similar to the View shown in Figure 4, illustrating another manner of mounting the reflector on the lamp; and
Figure 6 is a similar sectional view showing the deflector made integral with the lamp frame.
In the accompanying drawings, I have used the reference numeral 10 to indicate generally the lamp casing having on the inside the ordinary reflector and provided at its central portion with the bulb 11.
I have shown an ordinary lens rim 12 carrying the lens 13, which is pressed toward engagement with the forward portion 12 of the rim by means of springs 14.
My improved glare deflector indicated generally at A has the form of ahood, which is suitably mounted on the lamp at the upper left-hand portion thereof. It comprises a sheet of metal bent so that its edge adjacent to the lamp extends around about a quarter of a circle.
The rear edge of the deflector is curled or curved upwardly. .to. .iform.1a..channel flange The ereariedgeof the. deflector has .a. tongue j 16. ,c'ut ..thereifr.oin bent upwardly as shown infFigure-A. Thetongue 16 is se-. cured 1'10 flange 12 means of screw bolts or thejlikelta'fgifon' .thus'holding th d Hector; rigidly in place.
The mainbody 17 ofthecdeflector extends forwardly from, the'lamp casing 10, as shown beStI-n Figure 2,.and'is then curved inwardly at Its. intermediate,portion 18, as, shown in the drawings. The, intermediate ,portion 18 18 preferably slightly narrower than theportion 17, as shown in Figure-1.
Thev intermediateportion I8 terminates. in a tip I9, which extends to position spaced substantially in front of and extending across and directly in front of the center of the lens, as shown in Figures 1 and 3. The intermediate portion may be crimped at its edges, as at 20, for giving greater strength.
In the practical use of my improved glare deflector, two of such deflectors are mounted at the upper left-hand portions of the two headlights of a motor vehicle or the like. The tip 19 extending to a position in front of the bulb 11, but spaced substantially forwardly from the lens, serves to cut ofl the brightest rays of light, which would otherwise be directed forwardly and slightly to the left. These are the rays of light which tend to blind and confuse an approaching driver. They are deflected by the use of my glare deflector, and thus one great purpose of a desirable deflector, that of preventing the direction of blinding light rays toward an approaching driver 1s accomplished.
The undersurface of the deflector serves also as a reflector for directing rays of light downwardly and to the right for thus casting a light upon the side of the road, so that the driver can more easily see the drainage ditch or the sides of a bridge or culvert or the like, and may operate his machine with greater safety.
It will be noted therefore that I have ac-- complished two important purposes in preventing the projection of glaring rays in a direction toward an approaching driver, and in deflecting and reflecting rays of light toward the right side of the road, on which the vehicle equipped with my deflector travels for making that side of the road visible.
In Figure 5, I have shown a modified form of my invention in which the deflector A is provided at its end adjacent to the lamp with an upstanding flange 40, which fits under the edge of the lamp frame flange 12*. I provide a clip or fastener 41 having one end secured to the body of the deflector as at 42, made of annealed metal in the form of a strip, which can be bent around the lamp frame rim and bent under the'rear edge thereof, as at 43.
I preferably use two of the clips 41 and when they are installed in position, the portion 43 which is folded under the rim is engaged between the rim and the lamp frame 10, so as to be snugly held in place, and cooperating with the flange 40 for holding the deflector rigidly in position.
In Figure 6, I have shown the deflector A formed integral with the rim flange 12.
It will thus be seen that a variety of methods may be used for fastening the deflector on the lamp or it can be made integral with the rim.
My glare deflector is of very simple and inexpensive construction and can be pressed or shaped from a single sheet of inexpensive metal. It may be provided with a special reflector or lens inside, if desired.
The deflector should be made of noncorrosive material. Its size and shape may be varied somewhat for adapting it for installation on various kinds of lamps.
I claim as my invention:
The combination with an automobile lamp having a frame, reflector and light element, with a glare deflector curved at'its upper rear part to correspond to the curvature of the frame secured to the frame and extending substantially around the upper lefthand quarter of the frame, the deflector being channel-shaped and projecting forwardly and having at its enda narrowed portion projected downwardly in front of the center of the lamp, spaced therefrom a proper distance for deflecting a portion of the light rays, forwardly, downwardly and to the right, shutting off a portion of the rays directed forwardly, upwardly and to the left, and permitting the direction of diffused rays directly forwardly to light the road.
