The sockets 17 carry incandescent lamps of very 10W candle power, While the lamp carried by sockets 17 is very strong. The lamp carried by socket 17 is designed for general illumination, While the lamps carried by socket 17 are intended for use only When a dim light is required. The -sockets 17 and the socket 17 are on dillerent circuits so that the lamps may be lighted independently of each other.

This arrangement of the lamps is very advantageous in' motion picture theaters in Which a dim light is required at all times.

During the showing of the motion picture, the lamps in sockets 17 Would be lighted', to provide a dim light, and at the completion of y the picture the lamp iny socket 17 Would be lighted to give a brilliant illumination in order to enable persons to properly leave their seats in the theater.

By means of the flexible tubes 15 and 16, sockets 17 may be moved to various positions with relation to socket 17 .thus enabling a yvariety of elects.

It is obvious that the plate 9 may be used for one socket only, :that is, the socket 17 and the flexible tubes 15 and 16, and sockets 17 may be dispensed With.r

While the cover has been described provided With a guard, it is clear that a glass maydbe substituted for the guard when so desire The foregoing disclosure is to lbe regarded as descriptive and illustrative only, and not as restrictive -orvlimitative ofthe invention, of yWhich obviously an embodiment may be `constructed yincluding many modifications Without departing from the general scope vherein indicated and denoted in the appended claims.

Having thus described my invention, What y I claim as new and desire to secure by Letters Patent, is: u

1. In a ceiling fixture, a reflector provided with a small neck `portion having a rounded edge, an apertured cap havinga grooved portion removably receiving the rounded edge of said reflector, a neck in threaded engagement with the cap, an inwardly projecting flange on said neck, a plate secured to the underside of said llange, a rigid pipe and a ,n pair of flexible tubes attached to the plate,

Vand an outwardly extending flange on the neck by means of which the fixturermay be attached to a standard outlet box.

2. In a ceiling fixture, a reflector having an open top, a neck detachably secured to the reflector, apla-te supported by said neck, a

. rigid conduit carried by said plate and normally passing through the center of the open top of the reector, vand a pair of flexible socket carrying conduits supported by the plate and normally extending into the reflector adjacent the Wall thereof, adapted to be manipulated into position adjacent the rigid conduit so that the open top of the reflector may be readily drawn thereover to remove the reflector.

3. In a ceiling fixture, a reflector, having its lower edge substantially flush with the surface of the ceiling, a circular face plate surrounding the reflector and attached to the surface of the ceiling, andv an angled cover hinged to the face plate, said cover having a plurality of spaced barsextending to a centrally positioned ring to form a guard, and a latch extending from the face plate and adapted to have latching engagement With the angled cover.

l. In a Vceiling fixture, a reflector provided .I une, 1930. n
