ANTIGLARE ATTACHMENT 1 03 HEADLIGHT5.

Application filed May 7,

To all whom it may concern Be it known that l, Fawn L. EVANS. a citizen of the United States of America. and resident of Warsaw, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Antiglare Attachments for Headlights, of which the following is a specification.

This invention relates to headlights for automobiles and the like, and the said invention has for an object the provision of novel means for preventing the glare from the lamp from reaching the eyes of those who are approaching an automobile having a headlight of this character.

It is an object of this invention to provide a light deflector which can be readily applied to lamps now in common use, and which will prove effective in deflecting the light downwardly to the roadbed. prevent-- ing the beams of the light from being projected horizontally or vertically above the horizontal.

It is a further object of this invention to produce a deflect-or of the character indi cated which can be constructed from a single piece of metal and shaped to form a partition that will prevent the light from being visible through the lens above the partition, the other deflectors being also formed as integral parts of the said plate.

With the foregoing and other objects in view, the invention consists in the details of. construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a front View of a lamp, the securing ring of which is broken away to show the deflector applied thereto;

Figure 2 illustrates a sectional view of the said lamp and deflector, and a glare attachment.

In these drawings, 5 denotes the lamp body, 6 the reflector therein, 7 a lens and 8 a lens securing ring, all of which may be of conventional type, and as the details of construction thereof do not form a part of the present invention, further description thereof is believed unnecessary.

1923. Serial No. 637,309.

The anti-glare device or light deflector comprises, in the present embodiment of the invention, a ring 9 which is adapted to be fitted between the flange of the reflector or casing and the lens, in order that the anti glare device will be located at the rear of the lens.

In the construction of the device, a plate of metal or the like may be employed, and by a stamping process, the partition and the other parts of the device may be stamped and shaped practically during a single operation.

The ring has a transversely disposed plate or shield 10 from which fins 11 are formed by the production of slots in the plate and the bending of the material between the slots inwardly to positions oblique or diago nal with respect to the face of the plate, the inner surfaces of the said fins being finished to produce reflecting surfaces effective to divert the light downwardly to the roadbed. A rearwardly and upwardly extending partition 12 is also preferably formed integral with the upper edge of the plate, and the lower surface of the said partition is tinished to produce a reflecting surface so that light from the lamp will be thrown downwardly and outwardly to the roadbed, preventing any light from being visible through the upper half of the lens or through the lamp above the said partition.

Of course, under certain conditions, the plate 10 and the partition may be made separate from the ring. and in that event, the plate will be secured to the ring by fastenings 13 of any appropriate type.

When. the plate is formed as a separate 95 element, the plate could be foreshortened by the production of the outstanding shoulders 14 at the ends of the fins and such construction would perhaps give a better finish and appearance, and under certain conditions, it would be a preferable construction, although it is obvious that the fins could be formed by bending the fins outwardly without the formation of the said shoulders.

The metal employed in the production of the ring and anti-glare plate and partition may be of relatively light gage, since there would be no perceptible strain on the device after itis installed in the lamp.

I claim:

1. In an anti-glare attachment for headlights, a ring, a plate extending from one side of the ring to the other at the diameter of the ring fins formed integral with the plate and extending inwardly and upwardly to form reflectors, and a partition extending inwardly and upwardly from the said plate and adapted to arrest the rays of light radiating about the axis of the reflector.

2. In an anti-glare attachment for headlights, a ring, a plate extending from one side thereof to the other at approximately the center 01 the ring fins formed integral with the plate and extending inwardly and upwardly to form reflectors, the said ring being adapted to be held at the rear of a lamp lens, as and for the purpose described 3. In an anti-glare attachment for headlights, a ring a plate extending from one side thereof to the other at approximately the center of the ring, fins formed integral with the plate and extending inwardly and upwardly to form reflectors, and a partition extending inwardly and upwardly frem the said plate having a reflecting surface, the said ring being adapted to be held at the rear of a lamp lens, as and for the purpose described.
