' WALTER BAY GREENE, F A BRID E, PENNSYLVANIA;
Application filed April e,
My invention relates to a non-glaring headlight for use upon]motor vehiolesyand aims to provide'a novel and improved device of this character for efliciently directing the rays of light therefrom down upon the'roadway so as not to interfere with vehicles traveling in the'opposite direction.
Another object of the invention is the prothe major portion thereof of substantially cone shaped formationat the periphery of which there is a-forward-ly extending flange flared slightly outwardly as it extends forwardly and being slightly arcuate, said reflector being positioned with relation to the 7 electric light bulb and forward part of the casing so that all light rays reflected therefrom through the opening of the headlight will be in a downward direction.
It is also an object of the invention to provide a headlight of the kind indicated which is simple in construction, can be manufactured at a small cost, and will be thoroughly eflicient and practical in use.
With the foregoing and other objects in view,which will be apparent as the description proceeds, the invention resides in the construction andarrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawings, wherein: V
Figure 1 is alongitudinal section through my improved headlight,
Figure 2 is a front elevation of the reflector, and I Figure 3 is a. front elevation of the headlight.
In carrying out the invention, the numeral designates a cylindrical casing having de- 1926. Serial No. 100,641.
tachably secured to therear end thereof a slightly concaved end wall 11, and in the cylindrical casingagainst said'rear wallis' positioned a reflector 12, the detail construction of which will be set'forth asthe .d e' scription proceeds. The forward end of the cylindrical-casing 10 is tapered, as at 13, so
as to be gradually reduced 'in size as it extends V forwardly, to provide a restricted opening 14 at its forward end, and detach-.
ably mounted in said restricted opening is a v lens 15 through which the light rays are proj ected, said lens beingcarried by a frame 16 which may be removed from the opening;
14 with said lens. i i
WVithin the cylindrical casing 10 near the top of the concaved end wall 11 and secured in said end wall and reflector 12 is an electriclight socket 17 into which an electric lightv bulb 18 is mounted, and extending from this socket outside of the'headlight are the usual wires 19 for supplying the current to the bulb.v The bulb 18 is arranged above the horizontal plane ofthe uppermost portion of the restricted opening 14, so thatany light rays passing through said opening will necessarily be reflected from the reflector 12, which is of such shape or configuration that light rays reflected therefrom throughthe opening 14 will also be in a downward direction.
The reflector 12 has the major portion sub 2 stantially cone shaped, as at 20, and at the periphery thereof is a forwardly extendin annular flange 21 slightly arcuate or curved as it extends forwardly. The curve of the cone shaped portion 20 is alsovery slight, ex-
tending practically straight from the periphery to the center, as clearly shown in Figure 1 of the drawings, and at its upper end is provided with an opening 22 through which the lamp socket 17 extends, said socket ,being adapted to support the reflector in desired position, or at an angle with relation to the cylindrical casing 10, so that light rays from the upper part of said cone shaped portion 20 will be reflected in a downward direction through the opening 14 as well as on to the lower portion ofthe tapered forward end 13 of the cylindrical casing 10. Light rays reflected from the lower part of the cone shaped portion 20 of the reflector will I be in a more horizontal plane than those reflected from the upper part thereof as illustrated by the dot and dash line inFigure 1 of the drawings. Light rays striking the forwardly extending peripheral flange 21 of the reflector will be reflected back into the cylindrical casing lO and consequently aid in illuminating the interior of the headlight. The flange 21 extends at a greater angle from the cone-shaped portion at the top and bottom thereof than at the sides, as illustrated in Figure 2 of the drawings, so that the forward edge of said flange will snugly engage Figure 2 of the drawings. However, itis to beflunderstood that the device can be used without such coloring or dull surface if so desired. 7
At each side of the cylindrical casing 10 there is an apertured lug through which extend the reduced ends of a yoke or U- shaped bracket 26 carried by an upright post 27 forsupporting the same, said post 27 being secured to the vehicle in the usual manner.
In operation, the direct rays of light from thebulb 18 pass through the restricted opening l l in a downward direction, and light rays from the reflector 12 are also directed downwardly due to the specific configuration of the reflector, and. consequently all light rays from the headlight are in a downward direction onto the road and not in the eyes of drivers operating vehicles traveling in an opposite direction.
Having thus described my invention, what I claim as new is: i
1. A headlight of the character described comprising a casing having an opening in its forward end, a bulb positioned in said casing adjacent the top thereof, and a reflector positioned in said casing having a cone shaped portion and an annular forwardly extending flange arranged at the periphery of said cone shaped portion, said reflectorbeing positioned at an angle in said casing so that the lower portion thereof extends forwardly with the flange in engagement with the interior of the casing.irrespectiveof the fact that said reflector is arranged at an angle in the casing.
2. A headlight comprising a casing contracted at its forward end, a reflector mounted in the rear end of the casing and having a slightly conical body portion and an outwardly curved peripheral flange, said reflector being disposed within the casing with the upper portion of the conical body perpendicular'and the lower portion inclined forwardly; together with an electric lamp projecting from said reflector near the upper end thereof. r r
In testimony whereof, I have affixed my signature. v
