Application November 15, 1939, Serial No. 364,612
3 Claims. (Cl. Mil-45) This invention appertains to new and useful improvements in automobile headlights and more particularly to a headlight which incorporates means for eliminating the blinding glare which frequently causes accidents alt night.
The principal object of the present invention is `to provide a headlight `structure of substantial conventional construction wherein a light reflecting baiile is installed to cause internal deflection of the light to the end that the light will be projected from the upper portion of the reflector exclusively.
Other objects and Iadvantages of the invent-ion will become apparent to the reader of the following speccation.
In the drawings:
Figure 1 represents a vertical sectional view through the headlight structure.
Figure 2 is a front elevational View of `the head- 'ght case and reflector with the lens removed.
Figure 3 is a perspective view of the adjustment boss.
Figure 4 is a side elevational View of the deilector adjusting means.
Figure 5 is a vertical sectional view .througha modiiied form of the invention.
Figure 6 is a front elevational view of the structure shown in Figure 5.
Figure 7 is a fragmentary perspective view of the adjusting means.
Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1, that numeral 5 represents a headlight case while numeral B denotes a parabolic reiiector. A lens I is mounted at the front side of the case 5, while at the center of the reflector and case is a socket 8 for a bulb 9.
A slotted raised bracket I is secured to the lower portion of the reflector 6 and has the lower portion of a arcuate post Ill depending thereinto. The lower portion of the post II has laterally disposed trunnions I2 which extend into bearing formations I3 on the said bracket I0.
A horizontally and vertically curved deiiector Ul is secured to the post H by suitable means I5. The convex side of the deecto-r I'II opposes the concave side o-f 'the reflector 6. The reector It is adjusted by adjusting means |16 to properly set the deilector I5 with respect to the lamp 9 so as to throw .the beam upwardly against the upper portion of the reect-or 6 and outwardly, tothe end that there will be no upward glare from the lower portion of the reflector 6.
A hollow boss I'I is attached to .the lower portion of the case 5 and forms part of the adjusting means I6. This bos-s I'I has attaching ears I3 and a radial arrangement of teeth I9 with which teeth 20 on a knurled nut 2l can engage. As shown in Figures 1 and 4, a threaded stem 22 extends through an opening 23 in the boss I1 and thro-ugh the radial arrangement of teeth I9 and has a laterally disposed inner end portion 24 which is disposed into the lower portion of the post I I `and adapted to extend a slight distance beyond, at .which extremity the laterally disposed portion 2-4 is circumferentially grooved as at 25 to receive a key or the like. Thus the post Il is pivotally connected at its lower end to the stem 22.
The stem 22 has the adjustable collar 26 `thereon, between which and the toothed end of the hollow boss I1 a coiled compressible spring 21 is interposed.
KIt can now be seen .that the nut 2| canbe fed inwardly or outwardly on the stem 22 to properly adjust the deflector I4 to set the beam at the desired angular-ity.
In Figure 5 the deiiecto-r Na is secured to the front side of the arcuate-shaped post l Ia by suitable -securing means Ida. The adjusting means generally referred to by numeral [6a is of the same construction as the `adjusting means I6 and the lamp 9a is mounted behind the deflector Ma as in the form of the invention shown in Figure 1.
However, in .the form of the invention shown in Figure 5, a socket 28 is mounted on the forward concave side of a, deflector Ma for carrying a bulb 29. Thus the power o-f the headlight can be increased by the pro-vision of .a bulb behind the deflector Illa yand one at the front of the same. Furthermore, due to the location of the deflecltor Ma with respect to the lamp 9a and the position of the lamp 9a with respect to the deec'tor Ma, there can be no reection of light from the lower portion of the main reflector 6.
While th'e foregoing specification sets forth the invention in speciic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without `departing from the spirit and scope ofA the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
1. A light projector comprising a. reflector, a bulb mounted in front of the reflector, a light deflector in front of the bulb, a bracket on the lower por-tion of the reiiector, a post on which the deiiector is mounted, said post having its lower portion pivotally mounted on the bracket, a threaded member extending from a portion of the post below its fulcrum point and extending through a portion of the reflector, a boss on fthe outer side of the reflector through which the threaded member extends, and a nut on the outer end of .the threaded memfber operative against the boss to adjust the position of the post yand deflector.
2. -A light projector comprising a reector, a
l :bulb mounted in front of the reflector, a light deflector in front of the bulb, a bracket on the lower po-ntion of the reecftor, Ia post on which the deflector is mounted, said post having its lower portion pivotally mounted on the bracket, a threaded member extending from a portion of the post below its fulcrum point and extending through a pontion of the reflector, a boss on the outer side of the reflector through which the threaded member entends, a nut on the outer end of the threaded member operative against the boss to adljust the position of the post and defle'otor, a collar on the threaded member, and a compression spring interposed between the collar and the inner side of the boss.
3. A light projector comprising a reflector, a bulb mounted in front of the reflector, a light defieotor in front of the bulb, a bracket on the lower portion of the reector, a post on which the deflector is mounted, said post having its lower portion pivotally mounted on the bracket, a threaded member extending from a portion of the post below its fulcrum poinlt and extending through a portion of the reflector, a boss on the outer side of the reflector through which the threaded member extends, Iand la nut on the outer end of the threaded member operative against the boss to adjust the position of the post and deflector, said nut and opposed surface of the boss being provided With meshable teeth.
