JOHN M. B. LEWIS, or 'LYNCHBURG, VIRGINIA.

. HEADLIGET.

Application filed November 3, 1922. Serial No. 598,793.

To all whom t may concer/ni i I Be it known that I, JOHN M. B. Lnwis, a citizen of thev United States, residing at `Lynchburg, inl the county of Campbell and i State of Virginia, have invented certain new and useful Improvements in Headlights, of

which the following is a specification.

, This invention relates to headlights and more particularly toheadlights for automobiles wherein the direct rays of light are prevented from being thrown into the eyes of drivers of automobiles approaching in the .opposite direction.

i s is well known numerous attempts have been madeto provide non-glare headlights for automobiles, the usual method being to provide lenses having surfaces of peculiar .configuration whereby the rays of light are thrown downwardly. These devices `have not been wholly satisfactory since acertain amount of the vdirect rays of light are thrown in the eyes of drivers of approaching vehicles. y D

It is an important object of the present` invention to provide a headlight structure employing a lighting unit and a reflector both of which driver of a `vehicle approaching in the opposite direction.

Other objects and advantages of the/invention will be apparent during the course designates, as a whole, `metal lamp casing having of the following description.

In the drawings I have shown one embodiment of the invention. In this showing,

Figure 1 isa central vertical longitudinalV sectional view, and, Figure 21s a front elevation.

Referring a preferably sheet A a substantially horizontal central upper portion 11', the metal of the lamp Icurving upwardly gas at 12 toward the front end thereof and terminating in the relatively short horizontal portion 13. As shown in Figure 2 the forward end of the casing is substantially rectangular and the lamp slopes' downwardly yand rearwardly to a curved and enlarged rear, portion 15. The casing, is adapted to be supported in a bracket 16, be-

' ing adjustably secured thereto by bolts 17.

c opening 20 therein.

'Theforwardf open end of the casing is closed by a door 18 having the usual glass or lens 19. arran ed therein as shown. .The

door 18 has' a re atively narrow rectangular are screened from the view of a to the drawings the numeral 1 0" the light27 and reflectors 28 ,The door 18 isliinged4 at its upper end to the casing 10 asat 21,

while the lower end thereof is secured to the 22 carried by a stem 23 and casing by a nut adapted to engage within forks 24C carried, yby the lower wall 111 of the casing.

u The curved portion 15 of the casing nis p'rovided with a slot 25 -in which is mounted the stem 26 of an electric .bulb ory other lighting unit 27. A `parabolic reflector 28 is rigidly secured to the stein 26 and the latter, as shown, projects outwardly of theY l casing through the slot'25. rI`he'outer portion of the stem-26 is secured to a rod 29,

the outer end of which is threaded as at 30.`

A brackety 31 is secured to the-rear portion j of the casing 10 above the stem 26 of the lighting unit, and is provided with an opening in which the rod 29 is loosely mounted. Iiocks nuts 32 are threaded upon the rod 42S) upon opposite sides of thel bracket 32 Awhereby the positionof the lighting unit andits parabolic reflector maybe adjusted.

A reflector 33 is arranged in the upper portion of the casing as shown in Figure 1,

-the forward portion of the reflector curving4 upwardly as at 34 and terminating at a point space rlhe numeral 35 designates 'a light screen arranged in the upper forward portion of the casing, thescreen being hinged to Vthe casing as at 36. A threaded arcuate rod 37 is connected to the forward end of the screen 35 by an eyelet 38 and projects upwardly casing, anut 39 being threaded upon the upper end of the rod 37.

It will be seen in Figure 1 that the lower. and rear end ofthe rellector'33 is arranged at a point slightly above theupper line of the opening 20 as indicated by line therethrough. rlhe lighting element 27 andparabolicrelector 28 are arranged at a position wholly below the lower line of the opening 20 as indicated by the dotted line above the upper end of the reflector 28. It will be apparent that drivers ofvehicles approaching in protected from the direct rays of light from tue of their arrangement with respect to the opening 20v in the cover of the rays of light being indicated by the dot and dash line in Fi re 1. v"Ihe mountingpof the stem of the light permits adustment 'of the latter whereby t e paths o the rays of light may be variedl somewhat to from the forward end of the casing.-

the dotted the opposite direction are and 33 by vir.

18, the paths through an opening in the portion 13 of the v90 its forward end, an approximately horiserving as a reflector to reflect rays of light downwardly upon the forward portion of the machine and the ground adjacent the forward portion of the machine. y

It is to be understood that the form of my invent-ion herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my inventiongI claim:

,1. A device of" the character described comprising a casing having an opening in its .forward end` an approximately,hori; zontally arranged reflector disposed in the upper portion of said casing wholly above the upper line of said,openin'g,`the forward portion of said reflector being curved upwardly, and a lighting unit arranged in the lowerpoition of said casing rearwardly-of said reflector and wholly below the lower line of said opening. Y2. A device of the character described comprising a casing having an opening in zontally arranged reflector disposed in the upper portion of said casing above the upper line of said opening, the forward por- Ation of said reflector being curved upwardly,

a lighting unit arranged in the lower por- `tion of said casing rearwardly of said re- 'flector and below the lower line of said reflector having its frwardportion curved upwardly and terminating at a point spaced from the forward end of said casing, a screen pivotally connected at its upper end adjacent the forward end of said reflector, the lower edge of said screen being adapted to be arranged below the level of the lowermost portion of said reflector', means foradjnsting said screen, and a lighting unit arranged in the loweini'ear portion of said casing wholly. below the lower line of the opening therein.

In testimony whereof, I affix my signature.A
