JOSEPH W. HIGGINS, F BORDENTOVN; NEW JERSEY.

AUTcMoBrLn-HEaDLIeHT.

. Bordentown, in the county of Burlingtonv and State of New Jersey, have invented certain new and useful Improvements in Automobile-Headlights; and l do declare the following to be a full, clear, and lexact descrip tion of the invention, such as will enable others skilled in tlre art to which it appertains'to make and use the same.

This invention relates to improvements in headlights forl automobile and other vehicles, the principal object being to provide means whereby the rays of light from the lamp will be diffused and directed downwardly so that the drivers of approaching vehicles and pedestrians will not be blinded by the glare of the lamps.

An additional object of the invention is to provide a pane for a headlight through which a maximum amount of light. will be directed without any of the glare incident to such lamps.

With these and other objects in View the invention resides in the novel features of construction and arrangement of parts which will be hereinafter more particularly described and claimed and shown in the drawings wherein:

Figure 1 is a vertical longitudinal section on the plane of the line 1 1 of Fig. 2;

Fig. 2 is a front elevation of a headlight provided with a pane constructed in accordance with my invention;

Fig. 3 is a detail sectional view through the plate or pane before the same is fully completed; and

Fig. 4: is a fragmentary Vertical section showing a slightly modied form of my invention.

Referring to the ligures of the accom-- panying drawing wherein similar reference characters indicate like parts, it will be seen that the numeral 1 indicates a lamp casing of any ordinary or preferred construction provided with the usual source of light, in this case being an electric lamp bulb 2, a deliector 3 for projecting the rays of light from the lamp 2 forwardly through the plate or pane 4 covering the opening in the front of the casing.- The invention consists in the novel construction of this pane, 4the means for .holding the same within` the glare.

front of the casing depending upon the type of lainp with which it is used.

In most lamps of this nature the pane in the front thereof is circular and of a thickness depending upon its diameter. `There fore I preferably construct my invention so that it may be used'in place of any ordinary pane. it is of a thickness somewhat greater than the usual pane and is provided with a plurality of openings 5 extending transversely through the saine from its front to its rear face. These openings muy be of any desired number or size and ar ranged in any suitable configuration.

ln the present instancey the pane is in the form of a fiat plaie formed -of transllu'ent glass or other vitreous material. By thus providing a translucent plate the rays of light will be thoroughly broken up and diffused so that there will be practically no lin order to further overcome, the usual glare the openings are inclined forwardly and downwardly as clearly shown in "Figs 2 and The rays-oflight are thereopenings is below the horizontal plane oc-4 cupied by thelower edge of the rear end thereof.

ln the preferred form of the invention illustrated in Figs. l to'i', these openings are filled with a transparent glass or other.

vitreous material (i, thus preventing the entrance of dust or dirt within the casing of the lamp, and also keeping the light therein from being` blown out in case it is an acetylene or oil flame. The saule result may be also accomplished as shown in Fig. 4. That is to say, a thin plate ot transparent glass may be placed in front of the translucent plate containing the openings. ln this view, the last mentioned plate is designated by the numeral 4', while the numeral il indiA Cates the additional transparent glass plate:

The pane shown in Figs. 1 and 2 may be constructed in any coi'ivenient or desired manner, but the same is preferably lirst formed from a single piece of transparent glass in which the openings are provided as in Fig. 3, which is a partially completed pane. The openings may then be. lilled by pouring in a transparent glass in molten condition. This completes the pane, and when the saine has cooled, the material placed in the openings will be formed practically integrally with the other portion.

It is very obvious that a covering for the front of a' headlight when constructed as above set forth will be greatly superior to any similar covering already in use. Furtherrnore its simple construction enables it l to be constructed at a slight cost.

I claim:

l. In a lamp, a translucent plate having a plurality of transverse inclined openingsextending entirely through the plate from its inner to its outer face. a

2. In a lalnp of the, class described, a translucent plate formed of vitreous inaterial covering the front thereof, said plate having a pluralityof forwardly and downwardly inclined openings to permit the rays of light to be projected from the lamp in a downward direction.

3.l In a lamp of the class described, a translucent plate formed of vitreous ma terial covering the front thereof, said plate having a plurality of forwardly and downwardly inclined openings, the upper edge of the outer end of each of said openings being below the horizontal plane of the lower edge of the inner end thereof, whereby to prevent any horizontal rays 0f light from being projected from said openings.

4. In a lamp of the class described, a translucent plate formed of vitreous material covering the front thereof, said plate having a plurality of `forwardly and down'- wardly inclined openings, said openings being filled with transparent vitreous material to permit the rays of light to be projected from the lamp in a downward direction.

5. In a lamp, a translucent plate'provided with a plurality of transverse inclined openings extending entirely through the plate from its inner to its outer edge, and transparent means for closing said openings.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
