DIMMING HEADLIGHT FOR MOTOR VEHICLES Filed Dec. 8, 1927 Patented July so, 192
ICE-v JOHN ROCHE, F HOBOKEN, NEW JERSEY, ASSIGNOE 0F ONE-HALF T0 WILLIAM. P. I
VERJJON, OF HOIBOKEN, NEW JERSEY. I i I 1 i DIHMING HEADLIGHT JFOB MOTOR VEHICLES.
Application filed December 8,1927. serial No. 238,481.
My invention relates to a new and useful improvement in dimming head lights for motor vehicles, and has for its object to provide a new sim le and effective means for modif 5 ing or dimming'light rays from an electric lamp so as to avoid the glare heretofore incident to the head lights of motor vehicles, thus rendering the traflic upon crowded thoroughfare's less dangerous and less trying upon l0 the eyes of drivers.
Another object of my'invention is to so cover the reflector of a head light as to permit the direct rays of the lamp to pass through the coating and be modified in its reflection.
A further object of my invention is to provide for modifying the rays of light from the lamp by a suitable translucent covering upon the outer surface of the bulb of said lamp and' also to provide for the escape" for a cer- 2 tain amount of rays of light through uncoated portions of said bulb and further to provide for varying the amount of unmodified light which may issue through said bulb.
A still further object of my invention is to provide for controlling the amount of unmodified light issued from the bulb from the instrument board of the vehicle;
With these and other ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated-by the claims. j Y f" In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring surface, a' lamp positioned centrally of said by numerals bythe accompanying drawings forminga part of this application, in which Fig. 1, is a front view of the reflector of 40 a. head light containing my improvements,
the lens being removed.
Fig. 2, is a central vertical section Qf'Figtl,
' showing the translucent coating upon thereflector and upon a portion of the lamp bulb,
and one means of varying the amount of un-' obstructed light passing from said-bulb ,In carrying out'my invention, as herein em- I bodied, 10 represents the casing of a motor vehicle head light in which is mountedthe reflector 11 and this reflector has a super-imposed layer 12 of a translucent gum-like coat pass to the reflector and are returned thereing through which, when the rays of light thus modifying these rays so as to prevent an intense concentrated glare in front of the head light.
I provide a light regulating shield 15 having a shank 16 which is threadedvu on the lamp socket, the body'of the shiel being such as to close over that portion'ofthe bulb which is not coated; by which arrangement this shield may be rotated upon its axis, which Wlll cause it to move away from or toward the bulb, thereby permitting the outflow of a greater or less amount of light through the transparent portion of the bulb. This pro=- vides for increasing or decreasing the intensity of the light passing to the reflector through the super-imposed layer 12, thus giving the user of the head lights any illummation of the road bed which he may desire to meet the varying requirements of motor vehicle Of course I do not wish to be limited to p the exact details of construction'as herein shown, as these may be varied within the limitsofthe appended claims without departin from the spirit of my invention.
aving thus fully described my invention,"
what I claim as new and useful is:
1. A, device of the kind described including a reflector having a modified light reflecting reflector, said lamp'having a translucent front portion and a transparent rear portion, said translucent portion permitting modified light rays to reach the/modified light reflecting surjected onto the modified reflecting surface of rays passing to the modified reflecting surface.
said reflector, and meansjto cover a selected 2. A device a tlije'kind'dls'elosed includingi a reflector having its entire reflecting surface covered with a fil-m ofioolored light modifying substanoefa lamp positioned centrally reach the modified reflecting surface and the,
5 rear portion of said lamp being transparent causing unmodified light rays to be projected unto the modified reflecting surface, and
means removably mounted on the transparent portion of the lamp for varying the amount of unmodified light rays passing to said modi- 10 fied reflecting surface.
In testimony whereof I have hereunto affixed my signature.
JOHN ROCHE.
