YTONAWANDA, NEW YORK,

HEADLrGE'r nnrrino'ron.

Application filed May 3,

To uZZ ill/1.01M it may cancer-a.

lie it known that I, IVALTER I. SCHULTZ, a citizen of the United States, and a resident of 'lonawanda, inthe county of Erie and State of New York, have. invented a certain new and useful Improvement in Headlight Deflectors, of which the following is a speciiication.

This invention relates to an improvement .in headlight deflectors, particularly of the type in which the outlet is so formed that the eyes of pedestrians and motorists are protected against both direct and glaring rays of light from the lamps.

One object of this invention is to attain the above result without reducing the amount of light from the lamp; in contradistinction to certain types of deflectors now in use in which some rays are completely cut off so that the resultant beam is weakened and the effectiveness of the headlight is greatly reduced.

Another object is to provide a headlight deflector having a projecting visor which cuts off all the upwardly directed rays from the main bulb, which deflects such rays downwardly in front of the lamp and which cuts off all the horizontal rays from the auxiliary or dimmer bulb.

Other objects will appear from a consideration of the specification and of the drawings which form a part thereof and in which- Fig. 1 is a front elevation of one embodiment of the invention with the relative location of the main lamp bulb designated in dotted lines.

Fig. 2 is a cross section thereof taken on line 2-2 of Fig. 1; and

Fig. 3 shows somewhatdiagrammatically a transverse vertical section of a headlight to which a deflector made in accordance with this invention has been applied.

leferring to the drawings the deflector illustrated therein and designated by the numeral is preferably an integral piece of metal having a transversely extending window or opening 11 of irregular conformation. The lower part 12 of the deflector is curbed slightly outwardly from the plane of the flat annular marginal band 13 while the upper section is curved very pronouncedly from the band 13 and is hereinafter referred to as the visor 14. The window 11 which separates the two sections extends transversely across the deflector from one 1921'. set-mi No. 466,571.

side ofth e band 13 to the other and is widened at the center into the semblance of an eye, the visor corresponding to the eyelid. The inner surfaces of the visor 14 and lower section 13 are polished so that the rays striking thereon are not absorbed but are reflected back again.

As shown in Fig. 3 the deflector 10 is clamped to a headlight in front of the lens 21, which is preferably made of plain glass, by the holding ring 22 which engages over the marginal band 13. Inside the headlight 20 is a reflector 23 of the usual form, a main bulb 24 and an auxiliary or dimmer bulb 25. IVhen the deflector is in place the window 11 is directly in front of the main bulb 24: so that practically all the horizontal rays are unobstructed. The horizontal beam is composed not only of rays directly from the bulb 24 but also of reflected rays. I

The beam which strikes the ground in front of and near the car is made up entirely of rays reflected either by the re.- flector 23 or by the visor 14 or both. This beam is of great assistance to the driver since it illumines the ground and enables him to avoid rats and small obstructions not disclosed by the horizontal beam.

Experience has shown that the rays re flected upwardly from the lower part of the reflector are the most dangerous, in fact these rays make the lower half of the lens a blinding source of light. This is prevented by the opaque lower part 12 of the deflector. As stated above the inner surface of the part 12 is polished so that the rays, which, if the reflector were not used, would form the objectionable upward beam, are reflected back into the lamp and will eventually pass out through the window 11.

l/Vhile the part 12 cuts off the rays which would otherwise strike the ground directly other rays striking the visor are deflected to the ground in their place.

The visor 1st is forn'ied to eliminate all the direct horizontal light from the dimmer bulb and deflect it downwardly. This function. has not been illustrated because to do so would result in undue complications, but it will be obvious upon an inspection of Fig. 3.

While one embodiment of this invention has been shown and described, applicant is not to be limited thereto since it is obvious that other embodiments can be made without departing from the spirit and scope thereof as set forth in the following claim.

Having thus set forth my invention that which I claim as new and for which I desire the protection of United States Letters Patent is the following:

An integral headlight deflector applicable to automobile headlights having an annular marginal band by which it may be mounted at the front of the headlight and having two opaque parts within the confines of said band and a window extending transversely between points at opposite sides of said band and separating said opaque parts, the upper of sald parts havlng the form of a vlzor and extending in a general forward and inward direction from said band and the lower of said parts occupying a plane substantially inward of the front edge of said Vizor and being arranged to extend across and some what closely adjacent the lower portion of the lens of the headlight.

In testimony whereof, I affix my signature.

WALTER P. SCHULTZ.
