Dec. 29, 1936. w. F. LENNON HEADLIGHT Filed Aug. 11, 1934 Patented Dec. 29, 1936 UNITED STATES PATENT OFFICE HEADLIGHT William F. Lennon, Willimantic, Conn.
Application August 11, 1934, Serial No. 739,413
My invention relates more particularly to devices used upon vehicles for lighting the way, and an object of my invention, among others, is the production of a headlight in which the blinding glare shall be eliminated, and a further object of the invention is the production of a headlight having means for increasing the light at the righthand side of the road thereby enabling objects to be clearly distinguished. A still further object is the production of a headlight that while eliminating the glare shall at the same time clearly illuminate the roadway for a proper distance in front of the vehicle.
A still further object of the invention is the provision of a headlight that may be adapted to any device now in common use.
One form of a headlight embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawing, in which Figure 1 is a view in vertical section through a headlight embodying my invention.
Figure 2 is a front view of the same with the lens removed.
Figure 3 is a detail isometric view of the frame with vanes attached thereto.
Figure 4 is a detail view of a fragment of the frame showing its construction.
In the accompanying drawing the numeral 5 denotes the casing of a headlight which may be of any suitable form and composed of any proper material, said casing having a reflector B therein of any suitable construction, a lamp socket 1 projecting into the casing and having a lamp 8 attached thereto. A lens ring or frame 9 is secured in the open face of the headlight and a lens [0 is held in place by said ring in any usual manner, all of the parts thus far described being of old and well-known construction which will be readily understood by those skilled in the art.
In effecting my purpose I provide a frame H which may be composed of any suitable material and form, as shown herein this frame being rectangular in shape, although the particular shape is immaterial.
Vanes I2 are mounted in the fiecting surfaces.
These vanes are preferably slightly inclined, the front edges being lower than the rear edges.
They are attached at their ends to the sides of the frame in any suitable manner, and as a means for more rigidly supporting them rods l5 secured at their ends to the sides of the frame in any suitable manner extend across the frame and through notches l6 formed in the edges of the vanes and preferably at opposite edges thereof.
The frame I l is preferably yieldingly supported within the casing, as by means of springs H attached at the four corners of the frame as to eyes l8, and the opposite ends of the springs may be secured to hooks l9 engaged with the edges of the lens, and as shown in Fig. 1 of the drawing.
This frame may be arranged in any suitable manner, preferably with the vanes extending in a diagonal direction with respect to a vertical or horizontal plane extending longitudinally through the casing, and as shown in Fig. 2 of the drawing.
By the use of my improved headlight I have found that the road will be illuminated for a sufficient distance in front of a vehicle to answer all requirements, and at the same time the blinding glare is eliminated, the rays of light being projected to the right and below a horizontal plane. At a distance of approximately five hundred feet the lights are clearly visible and as this distance is decreased on approach the intensity diminishes to a mellow non-blinding light, allowing one to pass without being temporarily blinded.
While the frame may be supported with the vanes arranged at any suitable angle with respect to a horizontal or a vertical plane, I have found most satisfactory results to flow from an arrangement in which the vanes are supported at angles of forty-five degrees to such horizontal or vertical plane.
It will be'understood by those skilled in the art that other changes may be made in my glare eliminator without departing from the spirit of this invention, for instance, I may desire to make my glare eliminator octagon or round in shape instead of square as herein shown in the drawing.
In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
The combination with a headlight having a. reflector, a lens in front of the reflector and a light between the lens and reflector, of a light ray controller comprising a rectangular frame, an eyelet at each corner of the frame, spring suspension means for the frame extending between the corner eyelets and the headlight casing, a series of spaced parallel vanes confined within the frame and parallel with a pair of opposite sides of the frame, the vanes being of the same width as the bars of the frame, and means for 10 anchoring the vanes in the frame including the
