Appiieatin inea time 29, i925. serial No. 40,322.
a new and useful Improvement in a Headlight, of which the followin cation.
The' present-invention relates to improvements in headlights for motor vehicles and the like, and its particular object is to provide a headlight arrangement in which the light itself is hidden behind an opaque front cover so that no direct 'rays emanating from the source of light are projected forwardly.
It is further proposed to provide a fiat reflector above the light on an incline allo-wing rays of light emanating from the source to be reflected in a forward and downward direction so as to strike the road pavement for illuminating the same without striking the eyes of the driver o-f an approaching automobile.
It is further pro-posed to arrange the. source of light relative to the reflcctoi in such a manner that all the rays projected from the source, except those within the area of the reflector, are intercepted. y
It is further proposed to limit the beam issuing from the reector to a rectangular cross section whereby particularly the upper line of light is clearly defined.
It is further proposed to provide means whereby the angularity of the reflector relative to a horizontal plane or to the road pavement can be adjusted.
Further objects and advantages of my headlight will appear as the specification proceeds.
The preferred form of the invention is illustrated in the accompanying drawing, in which Figure 1 shows a front view of my headlight with a portion of the glass cover cut away.
Figure 2 a vertical section taken along line 2 2 of Figure 1, and
Figure 3 a horizontal section taken along line 8-3 of Figure 2.
lVhile I have shown only the preferred form of the invention, I wish to have it understood that various changes or modificag is a specifitions may be made within the scope of the have selected a oylindrial hou-sing 1 as" probably being best adapted for use in Vco'nnection with my lightl arrangement, loutit should be understood that any other suitable form may' be substituted provided it leaves sufficient Vroom for the interior arrangement forming part of my invention. An opaque disk 2 may be secured to a flange 3 projecting inwardly fromthe front edge of the housing by means of screws 4 or in any other suitable manner. The disk 2 is preferably made of metal and is provided with a rec:l tangular light opening 3 occupyingsubstantially the central portion of the disk. The
latter supports a box ('vcompr'ising a bottom 8 made substantially flush with the bottom line of the opening 3 and being substantially coextensive in width with the opening, the two sides 9 being somewhat higher in front than the height of the opening and slanting downwardly toward the. rear, and a rear wall l1 having a downward extension, as shown at 12, in which is mounted a lamp socket 13 in such a manner that a lamp 14 engaged therewith is disposed substantially centrally below the bottoni 8 of the box. To the top of the rear wall is hinged, as shown at 16, a flat reflector 17 preferably of rectangular form and of a width corresponding substantially to the width of the box, and of a length corresponding substantially to the length of the top edges o-f the sides so that the reflector would normally assume the slanting position shown in Figure 2, with its front edge. resting against theiear face of the disk 2. The position of the reflector may, however, be adjusted by means of a screw 18 held in the rear wall of the light housing with freedom of rotary motion but against endwise motion and threadedly engaging a socket member 19 pivoted to the back of the reflector as shown at 21. It will be seen that when the screw is turned from the outside of the light housing, the slanting position of the reflector will be changed.
rlhe bottom of the a central circular opening 22 substantially above the source of light, the opening being enlarged by two parallel slots 23 and 24 arranged to allow the rays of light emanating from the lamp 14 to strike the entire surface of the reflector while all the rays lying outside of the tranverse plane of the reflector are intercepted.
A glass 26 may be secured in front of the box 7 is provided with opaque disk 2 in a manner illustrated in Fig ure 2, that is7 by means of individual clips 27 secured 0n the edge of the glass and a ring 28 anged to engage with the clips and i proaching driver or pedestrian. The only light rays'thagt become active are those passing through theopening inthe bottom 8 and they strike the retlector and are reflected against the pavement in a downward direction so that they light the'V pavement where the latterushould be-lit without blinding the eyes of an approaching driver. The beam of light emanating from the reilector is turther controlled and clearly deined by the rectangular opening in lthe disk 2. -It will be `noted that the top and bottom edges of my construction are n the opening in the disk are somewhat below the top and bottom edges of the reflector which is of particular importance as far as ythe top edge is concerned, because any light rays which might be reflected from the top portionot the reflector in such a manner as te strike the eyes of -an approaching driver, are intercepted by the top edge of the openin il claim: l y y d In a headlight, a vertical opaque front plate formed with a Arectangular opening therein, a flat reliector mounted behind the plate on an incline so as to project light rays 4through the opening and a light mounted behind-the front plate below the opening and positioned below the reflector to allow light rays emanating therefrom to strike the rellector with a plate interposed between the light and the reflector' abutting the front and perforated to allow light rays to pass therethrough from the light to the reflector Within the area of the latter only. l
