HEADLIGHT F AUTOMOBILES Application filed August 24, 1929, Serial No. 388,225, and in Great Britain September 3, 1928.

This invention which relates to the headlights of automobiles, has for its object the provision of an improved means or device whereby the light can be rendered nondazzling to approaching pedestrians and vehicles and without in any waydimming or dipping the headlights.

Headlights for automobiles, wherein a translucent screen is interposed between the light source and the reflector, and is movable into different interposed positions, are known, said screen being movable by a remote control.

The present invention provides for a device of the above nature, characterized in that the screen is pivoted around the longitudinal axis of the reflector, or an axis parallel thereto, so as to be movable from a position normally above the light source into other interposed positions.

In a preferable embodiment, the screen is constituted by a transparent or translucent plate arcuated in its length and of taper shape in width, said plate being carried by a spindle rotatable in a bearing on the reflector and disposed parallel to the longitudinal axis of the reflector, the spindlebeing operably connected by a Bowden wire or other flexible cable to a remote control.

The invention is illustrated by the accompanying sheet of drawings, wherein v Figure 1 is a front view showing reflector, screen and light source, three positions of said screen being indicated.

Figure 2 is a longitudinal vertical sectional view thereof. 1

- Figure 3 is a fragmentary rear view illustrative of the means for operating the screen, said figure also showing a control.

Figure 4 is a diagrammatic view illustrative of the interconnecting of the screens of two headlights.

Like numerals of reference indicate corresponding parts in the several figures.

In carrying out the invention and referring to the drawings, the screen is constituted by a plate 1 of any convenient transparent or translucent material, arcuated in its length and of tapered shape in width, and inter- 59 posed between the reflector 2 and the light 3.

The screen is fixedly carried, broad end foremost, by the arcuated front portion 4: of a spindle 5 rotatable in a bearing 6 formed in one with or aflixed to the back of the reflector 2 aforesaid, said bearing having its axis parallel with the axis of the reflector 2.

The spindle 5 at its rear end is provided with an arm 7 detachably, but non-rotatably, mounted thereon, said arm 7 being normall vertically disposed and the screen 1 pos1-"60 tioned above the light 3 aforesaid.

A clip 8 grips the lamp socket 9 (which carries the light bulb 3) and also the bearing 6 aforesaid, and the arm 7 of the spindle 5 is connected to said clip 8 by means of a '65 spring 10 which normally tends to maintain the arm 7 in vertical position and the screen 1 above the light 3 so that full light is thrown forwardly by the reflector 2 aforesaid.

To the upper end of the arm 7 there is con-' veniently connected one end of a Bowden wire 11, or other flexible cable, the sheath 12 of which is connected to a bracket 13 on the back of the reflector 2, said wire 11 being carried and connected to a control 14: on the 75 dashboard 15 of the vehicle and within reach of the driver of said vehicle.

The arms 7 of the screens of the headlights are interconnected by means of a wire 9, rod or equivalent device so as to be operable in unison from the single control 14 aforesaid.

On the driver operating the control 14 aforesaid the screens 1 of both headlights are swung more or less round the light 3 and either side thereof according as said control 14 is operated by the driver to prevent dazzle on the on or oif side of the vehicle when meeting approaching pedestrians or extending rearwardly from the reflector, a spindle journaled in said bearing, a screen carried by said spindle, said screen being disposed between the lamp and the reflector and being rotatable by said spindle to different angular positions relative to the lamp and the reflector, a clip including portions embracing the lamp socket and the bearing to reinforce the latter, a lever carried by said spindle, a flexible member connected With 7 said lever for'swinging; the same to rotate said spindle and said screen, and a spring connected at one end With said lever and at its other end With said clip constantly tending to urge the lever, spindle and screen to a normal. position.

In testimony whereof I have affixed my signaturerheretor this. 12. day of August 1929. V JOHN BAYLEY.
