VEHICLE-LAMP.

Specification of Letters Patent.

Patented Jan. 11, 1921.

Application filed April 28, 1919. Serial No. 293,054.

To all w/zomit may concern Be it known that I, Fnnlmnien IV. \VAKE- rum), a citizen of the United States, and a resident of Vermilion, county of Erie, and State of Ohio, have invented a new and use.- ful Improvement in Vehicle-Lamps, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present lamp is of the general type known as spot lights, which are now in common use on automobiles, usually being attached to the windshield upright and being adapted to throw a brilliant beam ahead on the road. In the present lamp, means have been provided for furnishing a warning light rearwardly, and as the lamp is usually placed at the side of the machine, the present rear warning light serves to locate the side limit of the vehicle, thus aiding a following vehicle in passing. The lamp provides means for reflecting a portion of the light rays rearwardly, usually through a colored lens, so as to display a satisfactory warning signal. T 0 the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Figure 1 is a section through a lamp embodying my invention; and Fig. 2 is a similar section showing another form of my invention.

As shown, the lamp is of the usual type having an outer casing 1 which carries the reflector 2, the usual lens 3 and the bulb 4. The bulb is here shown as mounted in a socket 5 which extends through the casing and has a switch handle 6 at the rear. The

small disk 7 is adapted to adjust the socket and bulb but the operating means are not shown, as they form no part of the present invention.

In the form shown in Fig. 1, a tongue 8 is cut from the reflector and bent forwardly, the rear face 9 being polished so as to be a reflecting surface. A tube 10 is mounted in the casing being suitably attached to the reflector and this tube carries a lens 11 at its rear end, the lens being preferably of red glass, though any desired color of lens may, of course, be employed. The tube extends through an opening in the vertical drop face 12 of the casing.

The reflecting tongue is adapted to receive the light rays from the bulb, and reflect them rearwardly through the colored lens to furnisha warning signal. .The angle of the tongue will be such as to accomplish this result, and if desired the tongue can of course be curved to throwa more concentrated beam, although this is usually unnecessary.

In the form shown in Fig. 2 a tube is mounted on the casing, the tube extending in front of the casing and having a reflector 15 mounted in the inclined front face of the tube. An opening 16 is provided in the'tube adjacent the lens of the lamp and this is covered with glass, or other transparent material such as celluloid or the like. A suitable lens 17 is mounted in the rear end of the tube and the device is similar in operation to the first form, except that it is not inclosed in the casing. As shown it is attached to the casing by means of a bracket 19 in any suitable manner.

In the drawings the lamp casings are shown as tipped downwardly at an angle below the horizontal. This is the usual position of the lamp in use, and the rear reflector is set properly to throw the light rearwardly along an approximately horizontal line. This disposition will be varied according to the use the light is to be put to.

The present improvement gives a spot light which is very satisfactory as it does not detract from the beam ahead, and it adds the features of a rearwarning signal, and acts also as a passing light to position the side of the vehicle.

I claini- 1. In a lamp, the combination of a casing, a reflector mounted in said casing, a light source, a tongue ortion bent from said re-. fiector adjacent t e outer edge of the same,

a tube extending through said casing fitting said reflector around the opening formed by bending said tongue portion, a lens mounted at the rear end of said tube, said tongue por- 5 tion being adapted to reflect a beam of light rearwardly through said tube and lens.

2. In a lamp, the combination of a casing,

a reflector mounted therein, a light source, a

tongue portion bent from said reflector adj a- 10 cent the outer edge of the same, said tongue portion being set to reflect a beam of light rearwardly through the opening formed in said reflector in making said tongue portion, a tube inclosing such opening and extending rearwardly through said casing, a lens 15 mounted in said tube and adapted to direct the beam of light reflected from said tongue. Signed by me, this 24th day of April, 1919.

FREDERICK W. WAKEFIELD.
