The present'invention relates to fighting fixtures, and is more particularly directed toward enclosed lighting fixtures suitablefor office and n contemplates a lighting The present inventio fixture having a two part translucent envelope about the light source, the lower part being separable from the upper part to permit lamp bulb renewal, and the fixture having means to support the upper translucent cover member in position when the'lower diffuser is removed.

.The invention also contemplates an improved construction which .will afford adjustment of the lamp socketrelative to the securing devices employed for. supporting the lamp shade or globe.

The single figure of the accompanying drawing is a sectional view with parts in elevation, and shows, forpurposes of illustrating the present' invention, vention may take form, it beingunderstood that the drawing is illustrative of the invention rather than limiting'the same. V A pendant lamp socket I0 supports a lamp bulb indicated at I I, and is secured in place in a shell l2. The lower portion ofthe shell walls has a plurality of slots indicated at- 13, these slots having lateral communicating slots [4 and I5.

The shell l2 slidably receives an inner shell [6 and carries screws ll adapted to enter the slots 13, I4 and I5, so'as to adjustably secure the outer shell and inner shell together. The lower end of the outer shell is enlarged, as indicated at l8, so that it may receive the lip of the usual lamp shade. In the present construction, however, the lower orskirt portion l8 of the'shell I6 is provided with pummels I9 adapted to receive screws 20. These screws support downwardly and outwardly extending straps 2| whose lower ends are secured to an annular band 22.

The inner shell 16 is threaded, as indicated at 23, to receive a ring member 24 threaded as an embodiment in which the inr is flanged outwardly, as indicated at 25, and supports a dome shaped translucent cover member 26, the lower end of which is tightly received in the band 22, so as to make a dust-tight, rat- ,5 tle-proof joint. V

The band 22 carries a plurality of shade holding screws 21 and these support a lower diffusing bowl 28 which closes the bottom of the fixture. This bowl is preferably stepped, as indilo cated at 29, to support a reflector 30.

It is apparent that, within the scope of the. invention, modifications and different arrangements may be made other than is herein disclosed, and the present disclosure is illustrative Y merely, theinvention comprehending all variations thereof.
