HEADLIGHT DMMER.
Application filed July 17, 1924.
The present invention relates to headlights vfor motor vehicles, and aims to provide novel means whereby the light rays projected from a bulb of a lamp may be dimmed to insure against blinding of persons approaching the motor vehicle.
Another important. object of the invention is to provide a device ot this character which will be controlled by electricity, thereby previding a device which will be positively operated, and one which may be operated by merely operating a switch. j
A further object of the invention is to provide means for automatically returning the sectional housing to its active or dimming position after it has been operated to expose the lamp. Y
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment oi" the invention herein disclosed,l may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings:
Figure 1 is a sectional view through a lamp showing a dimmer constructed in accordance with the invention as mounted therein.
'Figure 2 is a diagrammatical view ot the circuit employed for operating the sections of the housing.
Figure 3 is a front elevational view disclosing the sec-tions of the housing in their v closed positions. v
AFigure 4 is a perspectiveview ofthe upper section oit' the housing.
Figure 5 is a perspective view of the lower section of the housing.
' Figure 6 is a perspective view of the core of the solenoid.
Referring to the drawings in detail, the reference character 5 indicates the lamp casing and the reference character 6 indicates a reflector positioned therein, the casing and reflector being of the usual construction The 'reference character 7 indicates a lamp socket inwhich the lamp 8 is positioned, the socket provided with laterally sei-iai No. masas.
ing pins 9 adapted to entend through the ears 10 of the housing sections to pivotally support the housing sections at a point adjacent to the lamp so that when the housing sections are moved to their closed positions7 the lamp will be substantiallyT housed within the sections.
As clearly illustrated by Figures 4 and 5 of the drawings, the upper housing section 11 is formed with an extension 12 disposed adjacent to its outer end which acts as a re- Hector to direct the light rays downwardly. rEhe forward portion ot the lower housing section 13 is formed with relatively straight end portions 1li providing a space to allow the light rays to be projected downwardly.
Secured to each housing section is a curved core 15, which cores move in the coils 16 that are secured to opposite sides ot' the lamp socket 7 by means ot the straps 17 that have connection with the bracket 17.
The battery 19 supplies electric energy to the coils 16 through the wires 2O and 21, the circuit to the coils being controlled by means of the switch 22 so that as the current passes through the coils, the cores 15 will be drawn into the coils to the end that the sect-ions will be moved into engagement with each other.
Spring member 23 is positioned on one of the pins 9 and has its ends engaging the upper and lower sections ot the housing to normally move the upper and lower sections to their closed positions.
In the use of the device, should it be desired to project the entire light rays oit a lamp, the sections ont the housing are moved to positions as shown by Figure 1 of the drawings, the movement being accomplished Vby operating the switch controlling the passage oi2 electric energy to the coils 16.
It is obvious that when the electric energy has been cut oil and it is desired to illuminate only that portion of the road directly in t'ront of the machine, the switch is moved to its inactive position with the result thati' the spring member operates to inovethelsecf" tions to their active positions. In view of the oregoing-f-detait descrip? tion' a further detail description as to' they operation of the devicetis, unnecessary,

adapted to be positioned around the socket, coils supported by the bracket, said coils being curved, curved cores adapted to move into the coils, a pair of housing sections pivotally supported by the bracket, said cores being secured to the housing sections to move the housing sections to thei-l'- open-po sitions When the coils are energized, and spring members for returning the housing,r sections to theii` closed positions.
In testimony that I claim the foregoing as my own, I have hereto utiixed my signuture.
