Description

June 20, 1933. M 1,915,193
HEADLIGHT Filed April 12, 1932 7 JOSEPH MflLY ATTORNEY VENTOR Patented June 20, 1933 PATENT OFFICE JOSEPH MALY, OF OLD BRIDGE, NEW JERSEY HEADLIGHT Application filed April 12,
This invention relates to headlights. One of the objects of the invention is to provide an eficient headlight so that the driver of an automobile, for example, may clearly see the way if the device of my invention is used on a car.
The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection With the accompanying drawing which forms'part of the application with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise c011- struction described and, therefore, such changes and modifications may he made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as 20 expressed in the appended claim.
In the drawing:
Fig. 1 is a central vertical section of one embodiment of my improved headlight; and
Fig. 2 is a front elevation of the device shown in Fig. 1.
Referring to the drawing for a more detailed description thereof, the device comprises a casing 5 which includes a parabolic rear end portion 6 hinged to the body of the casing at 7 and latched thereto by means of a latch 8. A pair of confronting reflectors 9 and 10 are disposed within the mentioned casing with a glass plate 11 between said reflectors. The reflectors 9 and 10 carry elec- 35 tric incandescent lamps 15 and 16, respectively, the light from said lamps passing through a plurality of spaced tubes 17 which are supported by the reflector 9 and a reflector 18 disposed in the forward portion of the casing. Said reflector 18 carries an electric incandescent lamp 19 at the center thereof.
A removably attached clear glass plate 20 is disposed at the front of the reflector 18, this glass plate to be used only when the lamps 15 p 5 and 16 are not lit, it being understood that these lamps are lit only when there is a fog. When there is no fog the lamp 19 is lit and the clear glass plate 20 is used. When there is a fog, I replace the clear glass plate 20 With a. plate of colored glass in order to dim 1932. Serial No. 604,800.
the light of the lamp 19, inasmuch as I have discovered that it is necessary for the most efficient action of my headlight, to dim the light from lamp 19 when the lamps 15 and 16 are lit. The clear glass plate 20 is preferably provided with a glare preventing reflector 21 formed integrally therewith and disposed in front of the lamp 19.
The tubes 17 may conveniently be a foot in length and I have found that the longer 0 these tubes are, the more efficient the device is. The clear glass plate 20 and the colored plate substituted therefor when the fog exsts, are apertured so that the forward ends of the tubes 17 may pass therethrough, as shown for the clear plate 20 in Fig. 1.
What is claimed is:
A headlight comprising a casing, a pair of confronting reflectors in the rear part of the casing, one of said reflectors facing forwardly and the other rearwardly, a lamp in each reflector, a third reflector in the front part of the casing, a lamp in the third reflector, tubes extending from the rearwardly facing reflector and supported thereby and also by the third reflector and adapted to transmit light emanating from the lamps in said pair of reflectors.
In testimony whereof I hereby aflix my sig nature.
JOSEPH MALY.
