LIGHTING-FIXTURE.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed December'22, 19-14. Serial No. 878,475.

To all whom it may concern:

Be it known that we, EARNST J. SOHWEIT- ZER and ROBERT G. WAGNER, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Lighting-Fixture, of which the following is a specification. t

This invention relates to lightlng fixtures and more particularly to fixtures for indirect lighting.

One of the objects of the lnventlon 1s to provide a lighting fixture havin a canopy with a reflecting surface throug WhlCll a light projects, said light being supported by a member carried above the reflecting surface.

Another object of the invention 1s to provide a lighting fixture having a canopy pro-' vided with a reflector, the canopy supporting a bowl suspended, some distance below the same into which a light projects, the rays therefrom being reflected downwardly by the reflector.

The invention also aims to provide a lighting fixture which is simple, practical, and which may be very cheaply manufactured.

With these, and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts, as will be hereinafter fully described, illustrated and claimed.

In the drawings: Figure 1 is a vertical sectional view partly in elevation showing the fixture provided with an inverted frusto-conical reflector; Fig. 2 is an inverted plan view of the spider which supports the incandescent light; and Fig. 3 is a longitudinal sectional view partly in elevation showing a fixture having a reflector with a concave reflecting surface.

Referring in detail to the drawings by numerals: 1 designates as an entirety a canopy below which is suspended a preferably translucent bowl 2 into which the incandescent light 3 projects. The canopy is preferably formed .of sheet metal and comprises an inverted frusto-conical reflector 4 having an annular shell 5 formed in tegrally on its upper edge. The reflector is formed with a central opening 6 through which the incandescent light 3 projects and is provided adjacent its outer edge with an annular flat portion 7. The shell 5 may be curved in any artistic manner desired such for instance as shown in the drawing and is shaped so as to create a shoulder 8. A spider 9 is arranged Within the shell 5 and the terminals of its arms 10 rest upon the shoulder 8. A lamp'socket 11 is connected to the under side of the hub of the spider by means of suitable fasteners such as screws 11 and an eye 12 is also connected to the hub for attachment to any suitable supporting means such as the chain 13.

To connect the reflector and the shell 5 to the spider 9 eye-bolts 14 are employed."

'a very soft and evenly distributed light.

In the fixture shown in Fig. 3 the canopy 18 is provided with a reflector 19 in the form of an annulus having a concave reflecting surface 20. Such a surface will concentrate the rays and produce a very strong light over a small area. The shell 21 is formed integrally on the edge of the reflecting surface and has a shoulder 22 which supports the spider 23 similar to the spider previously described. This spider supports in turn the incandescent light 24 over a bowl 25 connected to the eye-bolts 26 by links 27 in a manner previously described. It will be apparent that the canopies employed in the fixtures may be very cheaply manufactured and quickly assembled and that by a slight modification of the reflecting element the light rays may be either diffused or concentrated.

While we have shown the preferred embodiments of our invention, it will be understood that minor changes of construction and arrangement of parts may be made without departing from the scope and spirit of the invention as claimed.

What we claim is:

1. In a lighting fixture, an inverted frusto-conical reflector formed with a central opening, the reflector being flattened adjacent its outer edge, an upstanding shell formed integrally with the flata canopy having tened portion and provided with an interior shoulder extending around the same, a socket supporting member within the shell in engagementwith said shoulder, means connecting the socket supporting member to the flattened portion of the reflector, and a socket.

2. In a lighting fixture, a canopy having a reflector in the form of an annulus with a projecting concave reflecting surface, a shell formed integrally on the rim of the annulus and upwardly therefrom, said shell being provided with an interior shoulder, a socket supporting member within the shell engaging said shoulder, and means projecting through the reflecting surfaceand en-v gaging with the socket supporting member, and a socket connected to said socket supporting member.

In testimony whereof, we have hereunto set our hands at Los Angeles, California, this Hth day of December, 1914.

EARNST J. SCHWEITZER. ROBERT G. WAGNER.

In presence of- RODNEY M. SMITH, LORA M. BOWERS.
