Application filed November 30, 1921.

To all whom it may concern:

Be it known that 1', WILLIAM R. M

ANALLY, a citizen of the United States, and

a resident of Fort Dodge, in the county of WVebster and State of Iowa, have invented a certain new and useful Light Reflector, of which the following is a specification.

The object of my invention is to provide a light reflector of simple, durable and inexpensive construction.

More particularly, it is my object to provide a light reflector so constructed as to direct the bright rays of light downwardly and forwardly and to allow a suflicient spreading of the rays to properly light the road ahead of a vehicle on which the device is mounted without permitting any glare tending to blind those approaching the light.

With these and other objects in. view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a lamp equipped with a light reflector embodying my invention.

Figure 2 shows a vertical, central, sectional view taken on the line 22 of Figure 1; and

Figure 3 shows a detail, sectional view taken on the line 3-3 of Figure 2, illustrating part of the reflector.

There is an increasing demand for reflectors for lights used on motor vehicles and the like, equipped with reflectors adapted to spread the light from side to side suiiiciently for lighting the road to permit safe driving, which reflectors, however, are adapted to direct the bright rays of light downwardly and forwardly to the ground, so that they will not blind an. approaching person.

It is my object to provide a reflector, which will meet the demand just mentioned.

In the accompanying drawings, 1 have used the reference numeral to indicate generally a hollow lamp casing, having an open forward end provided with a rim or frame member 11 designed to be fastened to the casing 10 in any suitable way for hold ing in position the lens or glass 12.

Serial No. 518,817.

I provide in the casing 10, a lower rcflector member 13, shown in Figure 2, which extends from the sides and lower part of the casing near the front edge thereof in suitable shape for forming proper reflector and terminates just above the horizontal middle of the casing. The lower reflector 13 is designed to support a bulb 14 connected with an electric wire 15.

Supported at the upper edge of the re flector 13 and by means of one or more brackets 16 is a second reflector member or ray dlrecting member, which for convenience, I will call the inclined reflector. The inclined reflector has the form of a channel, having the rear wall member 17 and the top and bottom members 18 and 19. The channel shaped inclined reflector is curved from end to end as illustrated for instance in Figure 3, and is open at its forward lower end.

The rear wall 17 has an interior reflecting surface, while the lower faces of the walls 18 and 19 are provided with paint or other non-reflecting surfaces 20.

The lower wall 19 may have a curved notch 21 formed therein at its central portion. The lower wall extends downwardly to position where it stands in front of the upper part of the bulb 14L.

Mounted in the wall 17 is another bulb 22. A wall or partition member 23 is provided across the front of the casing 10 extending from the top thereof down to the forward edge of the upper wall 18 of the in clined reflector.

In the practical use of a reflector of the type herein described, the parts are so arranged that the light rays from the bulb 14: are deflected forwardly and downwardly and are more or less diffused.

Light rays from the bulb 22 are deflected downwardly, forwardly and laterally and give a good light on the road. No blinding glare is permitted and yet the road is thoroughly lighted for a short distance in front of the car on which the device is mounted and for a sufficient width to permit safety in driving.

part of the casing, a bulb holder at the upof the front of the casing to the other, and per portion of said reflector, a closure memhaving flat upper and lower Walls inclined ber extending across the upper front portion from their rear edges downwardly and for- 10 of said casing, a reflector and light ray di Wardly and a bulb holder at the back of 5 recting device mounted in the upper part of said latter reflectonsaid casing, having a rear reflecting wall Des Moines, Iowa, August 31, 1921. curved from end to end and from one side WILLIAM R. MQANALLY.
