HEADLIGHT-DEFLECTOR.

Application filed May'31, 1919.

To all whom it may concern.

Be it known that I, HOWARD O. CARTER, a citizen of the United States, residing at Detroit, in the county of Vayne and State of Michigan, have invented a new and useful Headlight-Deflector, of which the following is a specification.

This invention relates to head-light deflectors such as are employed to reduce the.

brilliancy and diminish the glare of motor vehicle head-lights;

It is the object of the invention to provide a head-light deflector comprising an opaque shutter covering the glass of the head-light and formed with a central aperture for allowing a limited radiation of light and to mount upon said shutter an adjustable vizor for regulating the direction and distance to which the beam of light passing through said aperture is thrown in advance of the motor vehicle.

A further object is to provide a deflector as above set forth, having fastening means whereby it may be quickly attached to'a head-light or detached therefrom.

A preferred embodiment of the invention is illustrated in the accompanying drawing, wherein,

Figure 1 is a view in side elevation of a head-light showing in sectional elevation the herein described deflector attached to said head-light, the section being taken on line l1 of Fig. 2.

Fig. 2 is a View of the same in front elevation.

In these views the reference character 1 designates a head-light which is encircled at its front by the bead 2 and is provided with the usual glass 3. 4 is a circular opaque shutter, preferably formed of sheet-metal, proportioned to substantially register with the glass 3 and having marginally secured thereto a plurality of spring clips 5 adapted to snap over the head 2 to retain said shield in proper engagement with the head-light.

Said shutter is centrally formed with an elongated rectangular slot or window 6 which extends horizontally when the dimmer attachment is properly positioned upon the head-light. \Vith said slot there is associated an angularly adjustable vizor 7 which is hinged to the shield 4 adjacent the upper edge of the slot 6 in parallelism therewith, as indicated at 8, and projects forwardly at a slight downward inclination. Provision is made for adjusting the vizor as regards Specification of Letters Patent.

Patented Sept. 14, 1920.

Serial No. 300,907.

this inclination, such adjustment being effected by an arm 9 which is loosely fastened to the vizor and is inclined upwardly therefrom toward the shield 4, its upper end being bent into parallelism with the shutter and slotted as indicated at 10 for engagement by a bolt 11, which, together with a wing-nut 12 forms a means for adjustably clamping said arm to the shield. Upon loosening said wing-nut the arm 9 may be subjected to a limited vertical adjustment to vary the inclination of the vizor to the shield. As illustrated, the desired loose connection between the arm 9 and vizor 7 is established by interposing a yieldable pad 12 formed of rubber or similar material between the vizor and the adjacent end of the arm, a rivet or bolt being )assed through the arm, pad and vizor. referably the under face of the vizor is highly polished or otherwise treated so that the rays of light impinging upon said face will be readily reflected.

The facility with which the above-described invention may be attached to a headlight or detached therefrom is highly desirable, since it enables a motorist to derive the full illuminating efficiency of the lights when traveling on rural roads, and to so reduce the brilliancy of the lights as to eliminate any glare upon entering a city or any district where such a regulation of the lights is either prescribed by law or rendered advisable by traffic conditions. The adjustability of the vizor gives control of the extent to which the road is illuminated in advance of the vehicle when the deflector is in use, lowering of the vizor serving to increase the downward deflection of the rays and to decrease the forward extent of the illuminated area, and a reverse effect being secured by raising the vizor.

What I claim is:

1. The combination with a head-light, of an apertured shield mounted thereupon at the front thereof, reducing the radiation of light, a vizor hinged upon said shield above the aperture thereof, and inclined to intersect the beam of light discharging through said aperture, an arm loosely secured to said vizor and inclined upwardly toward the shield, and means clamping the upper end of said arm to the shield permitting vertical adjustment of said end.

2. The combination with a head-light, of an apertured shield mounted thereupon at the front thereof, a vizor hinged upon said shield above the aperture thereof and inclined to intersect the beam of light discharging through said aperture, an arm extending from said vizor to the shield at an inclination to said vizor and shield, a yieldable pad interposed between said arm and the vizor permitting a limited angular movement of the arm relative to the vizor, and means clamping the upper end of the arm to 10 the shield permitting vertical adjustment of said end.

In testimony whereof I sign this specification.

HQWVARD O. CARTER.
