EDGAR J. LU'IWYCI-IE, OF CHICAGO, ILLINOIS.

AUTOMOBILE-HEADLIGHT.

Specification of Letters Patent.

Application filed April 10, 1911. Serial No. 620,011.

To all whom it may concern:

Be it known that I, EDGAR J. LUTWYCHE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and,

useful Improvements in Automobile-Headlights, of which the following is a specification.

My present invention relates particularly to automobile head-lights, my object being to provide an inexpensive substitute for the usual brass head-lights. To this end I provide a head-light of glass at a very small fraction of the cost of the ordinary brass lamp, the glass being so treated as to present practically the same appearance as brass. 'In this'way not only is the first cost greatly diminished, but also-the cost and labor of upkeep, as a brass lamp must be frequently polished, while the present glassrlamp need only be washed off.

With the foregoing in mind, my invention resides in the features of construction, and arrangement to be hereinafter de.- scribed with reference to the accompanying drawing, in which- Figure 1 is a horizontal section through the lamp and holding means, and, Fig. 2 is a vertical cross-section taken on line 2-2 of Fig. 1.

Referring now to these figures, the main or outer portion of. the lamp body 5 is substantially cylindrical in form, and has an enlarged forward end which is open and terminates in an even circular edge 6. The rear end of the main body 5 is reduced in diameter to form a'neck 7, the outer surface of which is formed with threads. This lamp body 5 may be molded with any number of circular ribs or beads 8 for the purpose of strengthening the same, and is.

openings in the upper portions of thebranches 12fpf a supporting'standard 13,

this standard having an apertured sup portingbase 14. The studs 11 may thus e adjusted to clamp the cylinder 5, and are' adapted to receive lock nuts 15. The lamp also has an interior casing 16 having thereto.

its enlarged end 17 closed to form the lamp front, and which is connected to its intermediate flared portion 18 by a circular shoulder 19 which fits closely against the circular edge 6 of the main body 5 and is cemented or otherwise securely fastened The smaller end of the interme diate portion 18 terminates in an elongated cylindrical neck portion 20 which extends into the neck portion 7 of the main body and is separated therefrom by a rubber ring 21. The light bulb 22, which extends Within the intermediate portion 18 of the casing 16, is held in one end of a tube 28 which extends through the neck 20. A metallic cap 24 screws upon the threaded neck 7 of the main body 5.

The main body 5 is formed of amber glass and has its inner surface silvered as shown at 25, thus rendering the same opaque and giving it the appearance of brass. The casing 16 is formed of crystal glass and the outer surfaces of its intermediate portion 18 and neck 20 are silvered, thus rendering the same opaque and forming a reflector to reflect the light out through the transparent front 17.

I claim: 1. A lamp comprising an outer. casing open at one end and having a reduced neckat its opposite end, a second casing within the first casing and having an exterior shoulder fitting against the edge of the open end thereofto close-the same, said second casing being closed at its outer end, and

having an intermediate portion forming a reflector, and provided at its inner end with a neck fitting'within the neck of the outercasing, and a source of light mounted in the neck of the inner casing and projecting into the reflector portion thereof.

2. A lamp comprising a glass body having diametrically oppos te side indentations, cushioning plugs mounted in said indentations, studs engageable with the cushions, and a lamp support to which the studs are connected. I

In testimony whereof I affix signature in presence of two witnesses.
