HEADLIGHT DEFLECTOR.

I Application filed October 4, 1924. Serial No. 741,548.

To all whom} it may concern:

Be it known that we, ANTHONY G. GIL- LO'l'r, Jessa BROOKS, and JAMES zens of the United States, Paterson, in the county of of New Jersey,

DEAN, citiand residents of Passaic and State have invented certain new and useful Improvements in Headlight Deflectors, of which the following is a specification.

This invention has reference to a deflector for use with various light projectors, where a reflector of considerable power is used to project the rays from the light forward; and is especially designed for use on headlights on motor vehicles that project very strong rays forward, which serves to interfere with the proper operation of an approaching vehicle, at night, and prevents the driver holes.

The object of the invention is to provide from seeing the road and approaching vean attachment for a head-light or similar light-projecting means, intercept rays from the that will efficiently reflector that would pass horizontally forward in the vision 'of a driver of an approaching car, and cause such rays to be directed downwardly on the road in'front of the car; but which will permit a small be transmitted; and

number of the forward rays to which device will be very simple in its construction, being formed out of a single disc of sheet metal and which can be readily constructed by cutting and forming dies.

In the accompanying drawing showing one embodiment of our invention, Figure l is a front view or elevation of the device.

Fig. 2 is a vertical section. Fig. 3 is a side elevation. Fig. 4 is a fragmentary view enlarged at one side of the device.

As shown in the drawing the structure comprises essentially a flat annular rim 2,

a and a series of flat bars 3, that are preferably integral with the rim. These bars 3 are of substantially to the end portion equal width from one other, and extending downwardly from the plane of the rim 2, in

so a curved contour.

and bottom towards a slight distance beyond the adwhereby the general contour of rojecting iiicent bar, the front of The bars from the top the middle portion each the device is convex.

At the rear of these bars their edges gradually increase the distance from the plane of the rim 2 from the top and bottom to the center portion, as clearly shown in Fig. 2. In other words the general contour of the rear face is concave.

It will be further seen that-each of the bars 3 extends substantially in a flat plane, from one end portion to the other end portion, but at each end portion 4, the bar will be somewhat twisted or irregular.

By the arrangement of the bars asset forth it will be seen, that a small number of horizontal parallel rays from the reflector can pass between the upper edge of one bar and the lower edge of the adjacent. bar, as

indicated by broken lines 5 and 6 in Fig. 2. This will assist in lighting the road at a distance, but will not interfere with the vision of the driver of an approaching car.

In the arirangement shown, the bars have the curves of their upper and lower edges substantially the same being formed on a radius substantially equal to the diameter of the rim 2. In the construction of this device it-is preferably-formed by taking a disc of sheet metal of a size equal to the rim 2, and then simply making cuts or slits across the disc on curves that have the same radius, the centers of such curves being equally spaced on a vertical line as indicated by the line 7, 8, 9 and 10 in Figure 1. This can be readily done byasuitable punch and die. The flat strips thus produced, are then'projected by a bending operation such as a bending punch that will cause these strips to form the configuration as described, and set forth in the drawing.

Obviously such two operations might be a Sign inuous operation of the same punch and It is obvious that a structure of this char acter is very simple and of low cost to produce; and at the same time it has proved very eflicient and satisfactory in its operation.

What we claim is:

A head light deflector comprising an anwith the 'flane of the rim and projecting the rim to a medial vertical section, to prodownwardly, eachbar extending in a subduce a concave contour at the rear, and a stantially fiat plane between the end porconvex contour at the front. tions, the bars being concavely curved at 5 the rear edges and convexly curved at the ANTHONY G. GHJLOTT- front edges, and which curves are at grad- JESSE BROOKS. ually increasing distances from the plane of JAMES DEAN.
