COMBINATION HEADLIGHT REFLECTOR.

Application filed February 5, 1924. Serial No. 690,747.

To all whom it may concern:

Be it known that I, ED'VVHITAKER, a citizen of the United States of America, and a resident of ater-loo, Black Hawk County, Iowa, have invented certain new and useful Improvements in Combination Headlight Reflectors, of which the following is a specification.

My invention relates to improvements in combination headlight reflectors, and the object of my improvement is to supply a lamp of this type with such a combination of reflecting devices about a source of illumination, that the light from said source shall be all substantially employed, and directed to illuminate a desired limited area.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated by the annexed drawings, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In said drawings, Fig. 1 is a vertical medial longitudinal section of my improved dgvice, and Fig. 2 is a front elevation thereo,

It is desirable and necessary that head lights of vehicles which include a relatively powerful source of illumination should also include means for segregating the directed light toward certain limited areas in advance to avoid inconveniencing the drivers of vehicles approaching from an opposite direction, and it is also desirable that substantially all of the light rays emitted by said source should be employed for that purpose without having a certain proportion lost because of being radiated into space without the desired limited area being properly illuminated.

My device is therefore contrived to secure both these desired objects, and of course both the elements of the lamp and the kind of source of illumination may be varied at will to effect these results.

In the drawings is shown in exemplification one kind of lamp comprising a lamp shell 2 within which is mounted a parabolic reflector 1, their interspace receiving the conducting wires of an electric-lamp bulb 9 mounted in a socket 8, the wires also be- Instead of mounting an electric lamp at or near the focal point of the reflector 1, I have mounted it adjacent the upper part of the inner reflecting face of the hood 6, an opening being provided in said hood to receive the socket 8 therethrough, and I have also provided a removable housing member 7 about said socket 8 secured to said lamp-jv shell and to said hood.

The numeral 5 denotes a fiat se, ;mental covering plate for the lower part of there; 1 flector 1, having its inner face provided-""q with a reflecting surface opposed to the re-" flector 1 and secured detachably to the lampshell below the hood 6. this plate 5 serving as a lower reflecting screen, and the interspace of the

screens

5 and 6 being filled by a transparent plate 10 mounted between clamping elements 11.

When the parabolic or other kind of concave reflector 1 has an opening as in ordinary lamps to receive a bulb-socket, and it is desired to apply the

screens

5 and 6 or either of them to the reflector as shown, the opening 3 may have a stem secured therein provided with a domical boss 4 having a reflecting surface, to prevent any interruption of the reflecting face of the reflector.

As so constructed and arranged, with the lamp 9 positioned above and forward of the focal point of the reflector 1 and near the hood 6, light rays from the lamp are reflected from the hood toward the reflector 1, and light rays which are directed from the lamp upon said reflector are in part reflected toward the reflecting surface of the lower plate 5, whereby the lamp rays are approximately wholly directed through the windowplate 10 and by the restriction of the

parts

5 and 6 are directed to illuminate a desired area ahead as indicated by the scope between the horizontal and vertical arrows in Fig. 1.

The light is thus dimmed for an approaching vehicle, and concentrated on the road properly.

Having described my'invention, What I claim as new, and desire to secure by Letters Patent, is:

A device of the character described, comprising a concave reflector, a curvate hood positioned across the upper front part of the reflector and having an inner reflecting face, a source of illumination adjacent the said reflecting face above the focal point of the concave reflector, and a flat reflector screen positiond across the lower front part of said concave reflector and with a horizontal upper edge spaced vertically from the loWer edge of said upper hood, the hood and screen cooperating in directing light emitted between them Within certain vertical limits and emitting light laterally between the hood and screen.
