NON-BLINDING DEVICE.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed February 17, 1915. Serial No. 8,701.

To all whom it may concern:

Be it known that I, EUGENE ADERENTE, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a new, simple, and useful device named Non-Blinding Device, for the controlling of the rays of glaring (blinding) lamps, of which the following is a specification.

This invention relates to a device adapted to be applied to high power headlights for automobiles and the like, the device being preferably, although not necessarily, in

the nature of an attachment applied to the glass of the lamp for the purpose of so influencing the rays that they will practically all be directed on the road or street surface without producing any blinding effect upon pedestrians or occupants of other vehicles, since the rays of light are directed forwardly in a line below the ordinary level of sight. I

- The invention has for its general objects to provide a comparatively simple, inexpensive audefl'ective non-blinding device for lamps which is of such design as to be housed within the reflector and prevent rays of light from being directed Skyward, while utilizing such rays by deflecting them downwardly on the road surface, the device consisting of a plurality of horizontally disposed spaced bars which may be silvered, nickel plated or otherwise formed into reflectors, and the bars are so designed and arranged that the rays of light from the lamp within the reflector can be directed forwardly, some between the bars of the device, without reflection, and some by reflection from one bar to another.

A more specific object of the invention is the provision of an attachment for headlights, the attachment being in the form of a ring having parallel horizontal strips of thin metal disposed with their flat surfaces in a horizontal plane so that rays of light can pass horizontally forwardly, and the rear edges of the bars being bent upwardly, whereby rays of light striking the under sides of the upwardly-bent portions will be deflected downwardly against the upper surfaces of said portions, whereby the latter will reflect the rays of light forwardly in a horizontal direction, and preferably the adjacent reflecting bars will be so spaced apart that rays reflected by the parabolic reflector can pass forwardly between the bars without being reflected by the latter, so that the attachment constitutes a device which not only prevents blinding of pedestrians and occupants of vehicles, but more brightly illuminates the road surface or materially increases the effective power of the lamp.

.With such objects in View, and others which will PPear as the description proceeds, the invention comprises various novel parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, and wherein similar characters of reference indicate corresponding partsin both the views, Figure 1 is a vertical section of a lamp with the non-blinding device applied thereto; and Fig. 2 is a front view of the lamp and attachment.

Referring to the drawing, A designates a reflector and B the lamp of a headlight which has the usual glass front.

The attachment comprises a plurality of connected sheet metal horizontal bars C set edgewise in ahorizontal plane, each bar having its rear portion throughout its length bent upwardly at an angle of approximately fifty degrees, these bars having their ends connected with a ring fitting the reflector, and they are disposed directly behind the glass front of the headlight. These bars serve as reflectors and hence they'are on both sides silvered, nickel plated or otherwise formed into reflecting elements. The upper edge of the upwardly-bent rear portion of each bar or strip is disposed below the level of the straight horizontal portion of the adjacent bar above, so that ample space is provided for the passage of the rays that are reflected forwardly by the parabolic reflector A, this effective space for direct reflection of rays from the reflector being indicated by the letter D, Fig. 1. The angularly-disposed reflecting portions of those bars lying above the focal axial line of the reflector receive 6-5 features of construction and arrangement of upper surfaces of the said portions, and these in turn reflect the rays forwardly from the headlight in a horizontal direction. Thus it will be seen that practically no rays are lost and no rays can be emitted skyward or in such a manner as to have a blinding eflect upon persons in front of the headlight with the eyes above the level thereof.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily under stood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent.

1. The combination of a headlight includ ing a source of light, and a plurality of reflector bars disposed in front of the said source and having upwardly-bent rear edges for receiving upwardly radiated light and directing it horizontally.

2. The combination of a reflector, a source of light disposed in the focal center thereof, and a plurality of reflecting bars arranged in front of the source of light and spaced apart to permit the passage of rays of light from the lamp and from the reflector, said bars having upwardly-bent rear portions whereby rays of light striking the rear portion of one bar will be reflected upon the rear portion of an adjacent bar and thereby reflected forwardly.

3. An attachment for lamps, comprising a ring having parallel reflecting bars spaced apart, the rear edges of the bars being bent upwardly in parallel relation.

4. An attachment for lamps, comprising a ring having parallel reflecting bars spaced apart, the rear edges of the bars being bent upwardly in parallel relation, the upper edge of the upwardly-bent portion of one bar being wholly below the superimposed adjacent bar.

5. The combination of a reflector, a source of light disposed at the focal center thereof, and a plurality of reflecting bars arranged in front of the source of light and spaced apart to permit parallel rays of light from the lamp and reflector to pass Without reflection by the bars, each bar having one edge bent out of the plane of the bar, the bent edges of all the bars being parallel, and the bent edge of one bar being spaced from an adj acent bar, and both surfaces of the bent portion of each bar being a reflector, whereby rays striking one bar will be reflected against an adjacent bar and thereby reflected parallel with the rays of light passing directly between the bars from the lamp and reflector.

EUGENE ADERENTE.
