LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filedJune 14, 1916. Serial No. 103,599.

and resident of Milwaukee, inthe county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Lighting-Fixtures, ofwhich the following is a description, reference being had to the of this specification.

The invention relates to lighting fixtures and more particularly to electric light fixtures.

The invention is designed to provide a lighting fixture in which the lighting may be both direct or indirect or either one of these. This is accomplished by mounting on a suitable support a pair of oppositely disposed sources of light with a deflector plate disposed therebetween.

A further object of. the invention is to provide an extensible support for the lights composed of telescoping sections with spring means for frictionallv holding said sectlons to permit of their adjustment.

The invention further consists in the several features hereinafter set forth and more defined by claims at the conclusion hereof.

In the drawings:

Figure .1 is a vertical sectional view of the device embodying the invention; and

Fig. 2 is an enlarged detail view of a part of the device shown in Fig. 1 showing the connection between the lamps, the support andthe reflectors.

The device comprises a support, a pair of oppositely disposed sources of light and a reflector interposed between said sources of light carried by said support.

The support comprises a tubular base section 4 and telescoping tubular sections 5 and 6, the section 5 telescoping withm the base 4 and the section 6 within the section 5. Means are provided for frictionally holding these telescoping sections with respect to each other for the purpose of adjustment and means are also provided for locking said sections in adjusted position.

The frictional holding means comprises spiral shaped springs 7 and 8 secured by pins 9 and 10 to the lower ends of the sections 5 and 6 respectively said springs depending below the ends of said sections so as to engage the inner sides of the sections 4 and 5 respectively whereby said sections lucid material, such as glass,

may be adjusted with respect to each other I and held by the springs in adjusted position. To fixedly secure the sections in adjusted position I provide set screws 11 and 12 passing through threaded apertures 13 and 14 in. the upper ends of the sections 4 and 5 respectively to engage the sections 5 and 6 respectively. 4

The upper end of the section 6 is provided with acap or plug 15 in which upwardly extending spaced apart lamp supporting and conductor carrying tubes 16 are secured. Telescoping within the upper portions of said tubes 16 are spaced apart lamp supporting and conductor carrying tubes 17 which are adapted to be secured in adjusted position with respect to the tubes 16 by set screws 18. The ends 19 of said tubes are threaded to engage in oppositely disposed threaded bores 20 in a hollow fitting 21. Secured to the fitting 21 are the lights and reflector. previously referred to.

The interior of the upper end 22 of the fitting 21 is threaded to receive the threaded end 23 of the socket for the electric lamp 24 and the interior of the lower end 25 of the fitting 21 is threaded to receive the threaded end 26 of the socket for the electric lamp 27.

The fitting 21' is provided with a shouldered portion 28 and, a tubular portion 29 threaded at its upper end for receiving a threadedlocking collar 30 forsecuring the reflectors for the lamps 24 and 27 and the reflector to the fitting 21.

The lamp-24= is provided with an upwardly projecting hemispherical reflector 31 of translucid material, such as glass, and having a central aperture 32 through which the portion 29 of the fitting 21 passes and the lamp 27 is provided with a downwardly projectmg hemispherical reflector 33 of transand having a central aperture 34 through which the portion 29 of the, fitting 21 passes. The lamps 24 and 27 are of translucid glass to allow a portion of the light to pass through them and at the same time reflect another portion of the light.

The .reflector consists of a circular opaque disk 35 provided with reflecting surfaces 36 and 37 and with a central aperture 38 through which the portion 29 of the fitting 21 passes.

Interposed between the shouldered portion 28' 0f the fittin and '19. Ynfltmfnv 22 ia n cushion 39 preferably a ring of soft felt and similar cushions 40, 4:1 and 42 are interposed between the reflectors 33 and 35, re-

flectors 35 and 31 and reflector 31 and collar 30 respectively. Thus the reflectors 31, 35 and 33 are all mounted on-the fitting 21 and secured thereon between the shouldered por tion 28 of said fitting and the collar 30.

Each lamp 24 and 27 is provided with any suitable form of socket switch which is operated by a pull cord 43, the pull cord for the lamp 24; passing down through apertures 44:, 45 and 46 inthe reflectors 31, 35 and 33 respectively. Thus both of the lamps: may beused or either one of them as desired.

Conductor wires 47 and l8-connected with any suitable source of supply pass upwardly through the tubular supporting sections 4., 5 and 6, the conductor wires t7 passing through one pair of telescoping tubes 16 and 17 into the fitting 21 and thence to the lamp 27 and the conductor wires 48 passing through the other pair of telescoping tubes 16 and '17 into the fitting 21 and thence to thelight 24. It will he noted that the tubes 16 and 17 extend from the support 'to a position wellwithin the reflector 33 so that reflectors of varioussizes maybe used without interfering with the support.

The light from the lamp 24 passes upwardly and at the same time some of it passes downwardly through the reflector 31 and strikes the reflecting surface 36 of the disk 35 and is reflected upwardly. The light from the lamp 27 passes downwardly and at the same time some of it passes upwardly through the reflector 33 and strikes the reflecting surface 37 of the disk 35 and is refie'ct eddownwardly. V V a While I have shown the device as provided with a base member more suitable for use as a floor lamp, it will be understood that the device may be inverted and suitably suspended from the ceiling.

The invention thus exemplifies a lighting fixture adapted for direct and indirect lighting and one in which the reflectors are simply and compactly mounted upon a fitting for the lamps.

What 1 claim as my invention is:

1. A lighting fixture comprising a support, a fitting mounted thereon, vertically disposed lamps secured at the opposite ends ofsaid fitting, a translucid reflector for each lamp, a metallic reflector disposed between said translucid reflectors, and means for detachably securing said reflectors upon said fitting.

2. A lighting fixture comprising apair of oppositely disposed lamps, translucid reflectors for each of said lamps, an opaque reflector disposed between said translucid reflectors, and supporting means including tubular telescoping sections, and springs-secured to the ends of the inner telescoping sections and bearing upon the inner sidesof the outer telescoping sections to hold said sections in adjusted. position.

3. A lighting fixture comprising an extensible support, a fitting mounted thereon, vertically disposed electric lamps secured at the opposite ends ofsaid fitting, translucid glass-reflectors for each lamp mounted on said fitting, and an opaque disk having upper and lower reflectingsurfaces mounted on said fittin between said glass reflectors.

4. A lighting fixtureincluding a fitting having an outer shouldered portion and a threaded end, vertically disposed lamps secured at the opposite ends of said fitting, glass reflectors for each of said lamps having centrally disposed apertures through which said fitting passes, a metal reflector having a centrally disposed aperture through which said fitting passes, said reflectors being mounted on said fitting between said shoulde'red portion and said threaded end, cushioning means interposed between said reflectors and fitting, and a collar fitting onto the threaded end of the fitting for securing said reflectors and cushioning means between it and said shouldered portion.

In testimon whereof, I aflix my signature.
