g/ ROMAN A. SCHMITT A TTURNEYS 1 ANTI-FOG HEADLIGHT WITH OPAQUE MASK caused -by reflection of light from water vapor in the fog. Various expedients were proposed to remedy this condition without success. Some expedients proposed involved use of transparent or translucent colored filters covering the entire headlight lens or selected upper or lower parts. These prior full or partial filters were not successful and did'not gain general commercial acceptance. The basic reason was that they failed to eliminate glare, and they objectionably reduced the fog penetrating ability of the light emitted by the headlamps.
I have discovered that a conventional sealed beam headlight can be converted into an anti-fog headlight by providing an integral or removable opaque, centered, right-angle cross mask on the headlight lens. This mask can be in front of the lens'or behind it. It can be manufactured as a separate attachment which can be snapped on the headlight or headlamp. It can be bonded to the lens or embedded in the lens of the headlight.
The invention operates by blocking the intense direct light beam from the incandescent filament of the headlamp. This light is internally reflected and comes out of the headlight in four separate diffused beams with high fog penetrating power. Glare is reduced due to the internal reflection and diffusion of the light beams emitted by the headlight.
Other and further features, objects and advantages of the invention will become apparent from the following detailed description taken together with the accompanying drawings, wherein:
FIG. 1 is a front view of a vehicle headlamp assembly embodying the invention.
FIG. 2 is a vertical sectional view taken on line 2-2 of FIG. 1.

FIG. 7 is an exploded perspective view of parts of the assembly of FIGS. 5 and 6.
FIG. 8 is a front view of a further headlamp assembly including headlamp and mask embodying a further form of the invention.

FIG. 12 is an enlarged top plan view taken on line l2-l2 ofFIG. l1.
Referring first to FIGS. 1, 2 and 3, there is shown a first headlamp assembly L1 for a vehicle. The assembly includes a sealed beam headlight structure 10 formed with a front externally convex transparent lens 12 and rear parabolic reflector 14 integrally joined peripherally to the lens. At the focal center of the reflector is incandescent filament 16 supported by spaced insulators 18 and terminating in electrical contact prongs 19 at the back of the reflector. The exterior of the transparent reflector is coated with a light reflective film 20. To the extent described the headlamp structure 10 is conventional. Now, according to the invention there is provided a mask 25 which converts the headlamp 10 to an anti-fog headlamp. Mask 25 is made of opaque material. It is secured to the inner concave side of lens 12. The mask has the form of a cross with vertical arm 26 andhorizontal arm 28 crossed at a right angle to each other at the center of lens 12. The opaque center portion 30 blocks a center beam of intense direct light from the centered filament 16, while arms 26 and 28 block beams in diametral vertical and horizontal planes. The mask preferably has an external black surface to prevent external light reflections. The mask may be composed of paint, lacquer or it may be made of metal or plastic cemented or otherwise bonded to the inside of the lens 12. In any case it divides the light emitted by the headlamp into four diffused beams passing through four separate quadrants 01-04 of lens 12. This effectively prevents glare formerly caused by reflection from water vapor in the fog of the direct intense beam emitted by incandescent filament 16. At the same time, the efficiency of the headlamp is not materially reduced since the light is emitted in a diffused divided pattern of four beams. Direct light emitted by the filament cannot pass through the lens in mutually perpendicular horizontal and vertical diametral planes blocked by arms 26, 28.
FIG. 4 illustrates another form of the invention in which mask 25 of headlamp assembly L2 is bonded between two abutted transparent glass layers 32and 34 forming lens 12A. As a furtheraltemative the mask can be embedded inside a single glass layer of sufficient thickness. In any case the mask has the right-angle cross configuration shown in FIG. 1.
The headlamp assembly L3 shown in FIGS. 5, 6 and 7 includes a sealed beam headlamp 10 provided with an externally applied separable mask 25a. This mask has a right angle cross structure. It is opaque and made of flexible, springy metal or plastic material. It is rearwardly bent tabs 36 at ends of its arms 26a, 28a. The mask can'be snapped over the peripheral rim 37 of the headlamp and will remain in place by spring pressure exerted by the tabs 36 on reflector 14. The arms 26a, 28a will flex to conform to the convex curvature of the lens 12. If desired, the arms of the mask can have an initial curvature to conform to the curvature of the lens. In any case the arms lie flush and snug against the front of the lens 12. The mask operates in the same manner as described above for reducing glare, improving fog penetrating ability and taking full advantage of the light beams without filtering or reducing them in intensity.
FIGS. 8-12 show another mask 25b which can be used in place of mask 25a on headlamp 10 to form the anti-fog headlight L3. Here the mask is formed of two flexible, springy opaque, black metal or plastic strips or arms 26b, 28b pivotally joined at their center by a rivet 40. The strips terminate in flexible tabs 36', 36". The mask in open right-angle cross position engages on the rim 37 at the front of the lens 12 of the headlamp as shown in FIG. 8, in the same manner as illustrated in FIGS. 5 and 6. When removed from the headlamp 10, the arms can be rotated with respect to each other from the open position of FIGS. 8, 9 and 10 to the closed position of FIGS. 11 and 12 where tabs 36 of vertical strip 26b abut and engage tabs 36", and arms 26b, 28b are juxtaposed to each other. In this position the mask can be conveniently stored in a glove compartment or other storage place to occupy minimum space.
The forms of the invention shown in 1-3 and 4 will be incorporated in the headlamps at the time of manufacture without materially increasing the cost of manufacture. The forms of the invention shown in FIGS. 5-7 and 8-12 are attachments which can be manufactured at low cost by mass production metal or plastic working machines. The masks can be mounted on conventional sealed beam headlamps and removed therefrom at any time.
All forms of the invention operate in the same basic manner described above. They will be found to fulfill a long felt need in the field. They will improve vehicular driving safety and reduce road hazards when driving at night or in fog. The invention can be used with headlights of land, water and airborne vehicles.
While a limited number of embodiments of the invention have been described, it will be understood that many modifications are possible without departing from the spirit and scope of the invention as described in the appended claims.
