To all wlwm it may concern:

Be it known that L'RIOHARD M. BEARD, a citizen of the United States, residing at the city; of New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Electric Lighting Fixtures, of which the following is a, full, clear, and exact description.

fixtures. v a

One of the'objects of the invention is to provide an electric lighting fixture having a reflector composed of a plaster composition which is reinforced in such a manner that it may be readily supportedv in position against the ceiling.

Another object is to provide a fixture having a reflector of a. plaster composition which may be readily attached to the part or parts utilized for holding the lamp and its socket in sition.

further object of the invention is to provide a fixture having a reflector of the type referred to, which is provided with convenient means for holding a globe or shade in :nOSitiOIl. T r I 'ith these and other objects in view, the invention consists of the constructions and combinations which will be hereinafter set forth in conjunction with; the accompanying drawings, and will be particularly pointed 1 out in the appended claims.

In the drawings: Figure 1 is a central vertical section of a lighting fixture constructed in accordance with the principles offithe invention;

Figure 2 is a bottom plan View of the re ceptacle for the lamp socket and its support in? plate igurc 3 is a top plan view ofthe reflector and lamp supporting element; and

Figure 1 is an enlarged detail showing the metallic reinforcement of the reflector.

The lighting fixture shown, as is usual with fixtures'of this type, comprises a ceiling reflector 1'which is preferably of a circular providedv at its central portion.

shape an with a frusto-conically-shaped portion or boss 2. This reflector is oflastic composition, such as plaster of aris, or any other suitable com osition, and maybe ornamented in any esired manner. The p rehector is provided with a lar central 0- 'lhis invention relates to electric lighting doctor. 7 Y

ing in the boss 2, and embedded within the walls of this opening is a metallic reinforcing strip or lining 3 which preferably has its upper embedded edge 4 curved, as shown, torigidly unite the reinforcing strip to the reflector. Preferably the reinforcing lining is embedded in the reflector by casting the reflector around the strip in a suitable mold. The lower portion of the annular reinforcmg strip 3 is provided with an annular flange 3' which rests against the bottom edge of the boss 2 and carries a ring 5 having set screws which secure a globe or shade 7 in place, the ri 5 and set screws fi-constituting a type o shade holder in common use. The shade or globe 7 may be of any suitable shape and preferably has an opening 8 in the bottom thereof and has its lower surface 9 to the line 10 translucent and the upper portion 11 thereof transparent so that the direct rays of light passing through the part 9 will be didused and the rays passing throu h the transparent ortion 11 will be re ected downwardly. y the reflector l.

Mounted within the globe or shade 7 is an electric lamp 12 which fits into a socket or receptacle 13, the socket or receptacle beingshown in Figure 2, and being provided with terminals 14 for the wires and 'holes or o enings 15 forrattaching it to a disk 16.

"spider. The disk 16 is supported from the spider by means of bolts or screws 22 passing t rough thearms 19, which screws may be adjusted to vary the position of the disk and hence the receptacle and lamp. The annular rin 18 of the spider is connected to the metal ic reinforcin 'stri 3 by means of screws 22'. The spider t erefore also supporting member for the reserves -as the Passing through a central opening in the disk 20 1S a standard or post Qtwhichis secured to the'spider by means of a nut 25, the post is carried byacoupling member 26 which is secured to an-outlet box 27,

which outlet box is preferably inserted in his receptacle is the common type of porcelain receptacle used; illv supporting reflector of plaster composition havin a cavity in the ceiling, as is the usual construction, the ceiling ine being indicated at 28. The electric wires which are attached to the terminals 14 of the receptacle pass into the outlet box through a pipe 28, the wires being indicated 29 and 30, which wires are attached to the terminals of the receptacle. c

The manner in which the fixture is assembled is obvious from the preceding description. The reflector is attached to the spider 17 by means'of the screws 22 and after the pipe 24 has been placed in osition, the reflector is held against the ceiiing and the nut 25 secured over the end of the post 24, the same being adjusted until the reflector is held tightly against the ceiling. The lamp receptacle 13 is attached to the disk 16 by screws passing through the openings 15 and these -parts are then secured'to the spider by means of the threaded bolts 22 which may be adjusted to vs the height of the lamp 12, which is threa ed into the socket or receptacle 13. The globe or shade 7 is then placedin position and held by the set screws 6. It will, therefore, be seen that the fixture described is capable of being readily assembled and placed in position, after which the parts are rigidly held there, the important parts of the fixture for this purpose bein the metallic reinforcing strip 3 andthe s ade spider 17. ,Iclaim: Q
