Specification of Letters Patent.

Patented Oct. 29, 1912.

' Application filed July 18, 1910. Serial No. 572,42

To all-whom it may concern Be it known that I, FRANK C. PARSCHE, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Automobile-Lamps, of which the following is a full, clear, concise, and exact description,*reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to lamps, and, while it has quite general application, is particularly concerned with automobile lamps, such as are used for headlights, and other lamps which are exposed to the weather.

Broadly, my invention resides in the arrangement for reflecting and projecting the light and, since in structures of this kind it is the primary object to provide forj the thorough protection of the light, in embodying the particular reflecting arrangement in a one-piece 'globe, part of which is preferably opaque.

y invention further resides in the arrangement for securing apositively Weatherproof construction, all this being consistent with the features of my invention above pointed out.

My improved reflecting arrangement com-.-

prises a layer of reflecting material applied to and carried directly on the surface of't'he protecting globe, it being understood, of

course, that only that part of the globe in Furthermore, I layer of Weather-proof opaque paint applied to the outside of the globe, particof; ther I ring, which will be -ularly opposite the layer of reflecting terial' and wherever else it is deemed Jsirable. v

Those features of my invention which provide for the weather-proof construction comprise an arrangement for securely con-' madenecting the globe and a metallic bracket in such a way that it is impossible for moisture to find its way to the interior.

My 1nvent1on is embodied in the structure illustrated in the accompanylngdrawing, in which'-- -Figure 1 is a side elevational view there- 2 is a central vertical sectional view e0 Fig. '3 is a view of the clamping described in detail; and Fig; 4 is a cross-sectional view of the ring taken on the plane of the line 44 of Fig.

Fig. 2. The ring 15,

The outside reflecting layer 22, is provided with a layer 23 of v come dislocated or 3, looking in a direction indicated by the arrows. 7

Like reference numerals are applied to the same parts throughout the various figures.

As shown in Fig. 1, an angle bracketli is mounted upon a standard 6, and is heldin any adjusted position by a set-screw 7. The bracket 5 terminates in a cup 8, which is internally screw-threaded and, as ShOWll-giil Fig. 2, is provided. with a central support 9- carrying a socket 10 for the reception of the threaded base of an incandescent lamp 11. The globe 12 is of glass and is of general spherical shape, having the closed head 13 and the rim 14 at its open bottom. The rim 14 is adapted to be surrounded by theclamps ing ring 15, the latter having an internal I bead 16 which engages in an annulargroove 17 in the rim 14, a gasket 18 of cork or rubber preferably intervening between the ring and the rim, as

as illustrated in Figs. 3 and 4, is made up of two parts which are joined together by tenon and mortise joints 19-19 in coiiperation with the pins 202 0. After the gasket 18 has been put in place the two halves of the ring may be'applied thereto, and after being pressed tightly in' position the pins 2020 may be'inserted in registering opening The exterior of the ring 15 is screw-threaded so that it-may 'fit into the cup 8, a set screw 21 being pro- .vided to secure the ring, and the globe carried thereby, in any desired position. 7 As illustrated in Fig. 2, the rear half of the inside of the globe is provided with a layer 22 of reflecting material, either silver or platinum, or any. other suitable substance. of the globe, in back of the opaque vitrified weather-proof paintwhich extends over the head 13, as illusti'ated in the drawings.

It is seen that asimple and eflicient structure is secured. There are no parts to be,- disarra'nged, and the light is reflected and directed alone by the a plication of the reflecting material u on'tfie clearly illustrated in inside of the globe and the relative isposi tion' of the opaque material upon the -out-. side of the globe. The globe, reflector, and

opaque covering are and so form a structural unit which has heretofore required a number of parts. The

reflectingmaterial may be applied to the practically integral,,

inside of the globe in any suitable manner while in a working state, and may then be set in any suitable manner so as to become permanent, it being clear, of course, that, in the broader aspect of my invention, the reflecting material may be applied to the outside of the globe.

I claim as new and desire to Letters Patent:

In combination, integral globe secure by a substantially spherical open only at the bottom, re-

flecting material applied directly upon the inside of the rear half of said globe, the outside of the rear half of said globe being covered with opaque material and the front half being transparent, a support upon which the bottom of said globe is secured,

a standard secured to said support and eX- tending into said globe, an incandescent electric lamp socket carried by said standard, and an incandescent electric lamp located at the center of said globe and screwed in said socket, the rays from the lamp being thus adapted to strike said reflecting material directly and immediately and being reflected through the transparent front of said globe.

In witness whereof, I hereunto subscribe my name this 14th day of July, A. D. 1910.

FRANK C. PARSCHE.
