Application filed June 9,

To all whom tmay concern.'

Ble. 1t known that I, CHARLES lV. RENNER, a citizen of the United States, residing at Altoona, in the county of Blair, Stateofv Pennsylvania, have invented a new and useful Headlight Ray Deflector, of which the following is a specification.

My invention relates to a novel construction of a headlight ray-deflector, lamp mask, W light-ra.

diffuser shade, glare, shade, or headlig t-beam modifier, ada ted to be applied to vehicle-lamps or eadlights, to searchlights, hi hiv-powered lanterns and other forms of light reflecting devices, for

l@ the purpose of dimming the glare-reflection of their lights.

M invention is es ecially adapted to the hea lights of antonio iles, .in which it is desirable to intercept the upward and to some extent the forward rays of the light, and deflect it to the` roadway to overcome the blindin glare, which as vehicles ap roach each ot er or approach an individua upon a roadway, tend to bewilder both the driver of the vehicle or the person coming into the path of the light; To theabove ends, my invention has for its principal object the construction of an inexpensive andeective defiector embodyau `ing an annular frame, from the upper por-` tion of which projects a series of arcuate louvers of di'erent lengths, which will possess the advanta of other more complicated and expensive structures, and, in addition, permit the employment of an ordiilary'` plain lens or'pa-ne of glass, in lieu of the expensive, special lenses now generally employed to comlply with special State legis-v lation relating t ereto.

un )For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same will give 1n practice satisfactory and reliable rew sults, although it is to be understood that w head ight ray deectorembodying my invention.

Figure 2 represents a vertical section on line'2-,2 of Figure 1. l

Figure 3 represents a perspective view of lamp, w ich may 1920. Serial No. 387,526.

Figure 4 represents on a reduced scale a' slde elevation of my deflector applied to a headlight.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings :m

1 de si nates a. ty icalheadlight or other Y he of any desired construction embodying an outer casing or body and a suitable internal reflector, two of these headlights being shown in Figure 3 as mounted upon the front of an automobile 2, 1n any conventional manner.

My novel deflector consists of a preferably circular frame 3, of metal or other materialg and preferably also formed with a vertical or radially and outwardly extending rear flange 4, the dimensions and outlines of which enable it to be readily applied or secured to the body of the headlight'proper by any preferred means, such, for instance,

as the bolts 5 or the like seen in Figure 4.

The frame or rin 4 may be fitted or se-l cured to the headlig t or body by any other fastening means, and serves as a carrier for a plurality of graduated, inclined, separated, crescent-shaped shades or refiectors, which in the art to which my invention apertains are usually denominated arcuated ouvers.

I preferably employ four of these louvers designated from the uppermost to the lowermost, as 6, 7 8, and 9. The light reflecting surface of each louver. decreases from the top l louver to the bottom one, that is, the uppermost louver 6 has a forwardly and downwardly inclined extension, whose light reflecting area is greater than the next louver 7, while the corresponding surface of the louver 7 is greater than the corresponding surface of the louver 8, which latter has a greater -reecting area than the bottom louver 9. @therwise .to express it, the forwardly extending, central, ,light reecting area of each louver decreasesl downwardly, so that, considered together, they constitute a series of Voverhanging reflectors whose light reecting surface increases from bottom to top, the effect of which is to cause the -downward deflection of the light emanating from about the u per half of the flamp and cause it to be t own upon the areas, arcuate and deflected wnwardly an road, rather than directly forward in a horizontal plane.

It wil be apparent that in my device, plain glass discs maybe employed in the headights, and that, if desired, no glass discs ma be employed, but it is of course prefera le to use an outer glass disc to revent d irt, dust and moisture from sett ing on the usual reflectors or their electric lights. It will onsequentl be seen that in my device in the Icase o the breakage of either one or both glass discs, an 'automobilist can proceed at night to his destination, as my device will `function effectively even if both glass discs should accidentally become broken, since the provision of the louvers having their light deflectin and reflectin decreasing from the top downwardly, as described, will .eii'ect the desired results under all conditions.

AInasmuch as the series of louvers which I employ is extended downwardly only to about the middle of the frame or ring .4,

it will be" a parent that the louvers willi affect orhde ect only such portion pf the light 4as in the il-lustrationfis thrown for-- ward through .about the upper half of the headlight, which .permits the light rays emanating from the lower halfof the headlight or lamp below its diametric horizontal center to be projected forwardly in a proper manner, the general collocation of said louvers being understood from Figure 2.

I4 do not, of course, confine myself to any special d-imension for the light deflecting areas of the louvers as a group, but said area ineach louver decreases downwardly, or gradually diminishes in extent, outline and area, so that the lowermost louver 9 is about half the size of the uppermost louverl 6, while the two intermedlate louvers are aduated' las to their li ht reflecting or eflecting area between t e dimensions of the uppermost and the lowermost of the up, so that said area of each louver ecreases from the top one downwardly, and it will be apparent that the proportioning or collocation of the louvers may bevaried accordi to requirement both as tothe'number o louvers employe the distance. they are spaced apart,and the 'extent of their li ht rellecting and deecting a it being, ho ever, essential that said area o each louver decreases downwardly. method vof connecting the louversLto" their frame-4 may. obviously be varied- In nation of the louvers, Lthe deflected rays may be caused when the device is used upon an automobile, to strike the ground at such distance in advance of the latter asvmay be desired.

It will now be apparent that I have de- .vised a novel and useful headlight ray deilector which embodies the features of advantage. enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instanceyshown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that such embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Havin thus described my irfvention, what I czim as new and desire to Secure by Letters Patent, is

In a head light. ray deiiector,'an annular fraine, and a plurality of crescent shalped forwardly -and` downwardly 'inclined ouvers located in the upper portion only of said frame, and projecting forwardly therefrom and having their outer terminals attached to the curved side walls of said frame,4 the reiiectn area of each louver decreasing downwar ly from vthe up r to the lowest louver, the rear curved. ge of the upper louver being secured to the upper inner periphery of said frame, and the lower louver havin its outer ends secured to said frame on dian line of said frame, the space between each ofA said louvers and below the lower llouver being entirely open and unobstructed,

and the forward upper edge of each louver beingbehnd the upper e ge ofthe louver immediately above 1t. l CHARLES W. RENNER.
