NCNDESCENT ELECTRIC EADLIGHT.
Specification of Letters Patent.
Patent-edi Maty 26 i914.
Application filed Tune 17, 1912, Serial No. VGfLIQ.
To all 'whom it may concern Be it known that I, CHARLES lV. Daun, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement lin Incandescent Electric Headlights, of which the following is a specification.r
My invention relates to incandescent electric headlights for locomotives and the like.
It is illustrated' somewhat diagrammatically in the accompanying drawings, where- Figure l is a longitudinal section with parts shown in full lines; Fig. 2 is a front view of the lamp.
Like parts are indicated ters in all the figures.
A A is the base, B the body and C the back of a reflector casing which contains the`headlight-reflector D suitably mounted on the standard l)1 and the support DE. At the front end of the casing' is mounted the tubular projection E carrying the glass El. This projection is mounted in any desired manner so as to be removable or hinged or otherwise manipulated to permit access to the interior of the casing and reflector.
F, F are a series of brackets mounted at G, Gr in the forward rim of the reflector casing. Eachbracket carries an incandescent lamp J and a lamp reflector K.
I do not wisli to be limited as to the form or size or shape of the headlight reflector' or the lamp reflectors or the lamps. In the form in which I have illustrated my invention it presents a parabolic reflector properly placed in the casing and a series of incandescent lamps arranged beyondthe reflectorl and extending inwardly over the edge ihercof. .These lamps are associated each with a lamp reflector which tends to throw the light of such incandescent .lamp down into the body of the headlight reflector. Obviously the curves and surfaces will be so related and adjusted and the lamp so positioned as to get that particular result desired. It is obby the saine letviously possible by varying the arrangement By 'utilizing the lamp reflectors the ,lamps can be placed at the outer rim of the headlight reflector', thus leaving a. very large free 55 space in front of the headlight refiector. This free space is of a diameter measured by the distance between the iunerrnostedges of' the opposed lamp reflectors for the outer portion of the incandescent lamp bulb is 6o negligible as a light interrupting medium. The lamps and the lamp reflectors can be adjusted or removed and others substituted without difficulty by temporarily removing the tube'E or the glass which covers its outer G5 end. This arrangement of Athe incandescent lamp permitsa very large number of them to be used. T hey project inwardly toward the axis of the light reflector and their nonluminous portions are entirely outside of the 7 0 path of the light forwardly directed by the` headlight reflector. I
I claim:
l. An electric headlight comprising a bowl-shaped reflector with a plurality of incandescent electric lights grouped about the outer edge of said reflector projecting in wardly into the field thereof but inclined away from the focal point,` the bases of said lamps being' located outside of the field of S0 the reflector, separate reflecting surfaces one for each lamp located about the periphery of Vthe reflector and adapted to direct the rays from each lamp toward the center of the reflector'. .85
2. An electric headlight comprising a bowl-shaped reflector with a plurality of incandescent electric lights grouped about the outer edge of `said reflector projecting inwardly into the field thereof but inclined away from the focal point. the bases of said lamps boing` located outside of the field of the reflector. separate reflecting surfaces one for cach lamp located about the periphery of the. reflector located partially Within the field thereof and adapted to direct the rays from each lamp toward the center of the reflector.
Signed at Chicago, Illinois, this 10th day of June, 1912.
