GLOBE norms.

I Application filed September 13, 1924. Serial-No. 737,474,

My invention relates to lighting fixtures and particularly to a holder for mounting a globe on a support or a suspended member. Lighting fixtures that are provided with a shade and a globe are often attached to the husk by a number of screws or other separately-acting devices that require a number of manual operations inassemblingthe fixture. desirable feature, particularly in large fixtures, is to avoid such structures and to provide means comprising a small number of parts that can be easily and quickly operated to assemble and disassemble the globe and shade, so that all of the rather cumbersome parts may be secured together ina single operation.

In large globes there is usually some irregularity inthe size and shape of the globe flange and there is also considerable con-, traction and expansion by reason of heating and cooling of the globe, which causes breakage of the globes where the flange is rigidly clamped. I provide a holder which adjusts itself tosuch irregularities and which permits a limited amount of expansion and contraction of the globe.

It is, therefore, one object of my invention to provide a holder which shall attach all the parts in one operation, and which shall adjust itself to the irregularities in the globe and the shade. I

Anotherobject of my invention is to provide a globe holder which shall positively unite the globe, shade and support, and shall provide means for the expansion and contraction of the globe after it is mounted.

Still another object of my invention is to provide a globe holder which shall comprise a small number of parts and shall be inexpensive to manufacture.

In the drawings constituting a part hereof and in which like numerals designate like parts,

Fig. 1 is an elevational view partly in cross section, of a lighting fixture.

Fig. 2 is a top plan view of the keeper ring, and

Fig. 3 is a bottom plan view of the sup port.

Fig. 4 is an enlarged view of a portion of Fig. 1, showing in detail the manner of attaching the globe and shade.

The illustrated lighting fixture comprises a bell-shaped support or husk 1 in which a lamp 2 is mounted and from which a globe 3 and a shade 4 are suspended. The support 1 is provided with an inwardly turned flange 5 and with an upturned circular flange or collar 6 that is provided with pins 7 spaced 180 apart. The shade and globe are supported by means of a keeper-ring, which comprises a collar member that is adapted to fit into the upturned flange 6. The collar member 8 is provided with two L-shaped slots 11 that cooperate with the pins 7 for attaching and locking the keeper-ring.

The collar 8 is further provided at its lower attaching the shade 4 to the flange 5 by inserting pins 14 in the enlarged portions 15 of double key hole slots 13, and then turning the shade so that the pins are in the small ends 13 of the slots. The globe 3 is then raised by means of the keeper-ring, and the pins 7 are entered in slots 11. By turning the keeper ring, the pins are locked in notches 16 or 17, as the case may be, accord ing to whether the shade or globe alone or both shade and globe are mounted. The

springs 12 bear against the glass globe to thereby unite the shade and globe, but in such manner that irregularities in the globe flange are compensated for by the springs 12, and a slight movement of the globe, by reason of its expansion or contraction, is

permitted. If desired, a washer 18 may be inserted between the globe and shade.

My invention thus provides means for positively holding the shade and globe. The holder allows expansion and contraction of the glass parts as well as a considerable variation in the size and shape of the glass flange of the globe, without causing it to break.

Although I have described-a specific embodiment of my invention, I do not wish to be limited thereto,- since my stru u e my be modified in various ways. For example, a different type ofv spring, such as a coil spring, may be used in place of the spring that I have shown. Other modifications will suggest themselves to those skilled in the art without departing from the spirit of my invention, the scope of which is defined in the annexed claims.

I claim as my invention:

1. A lighting fixture comprising a globe, a

shade, a support, a circular collar in saidsupport, means in said shade and collar for loosely sus oendin said shade. a flan ed rin supported in said collar, and means on said flanged ring for resiliently supporting said globe and shade.

2. A lighting fixture comprising'a globe, a shade, a support, a flanged circular collar extending upwardly 'in said support, means in said shade and collar for loosely suspending said shade,v a flanged ring supported in said collar, and means. on saidflanged ring for resiliently supporting said globe and shade.

3. A lighting fin ure comprising a globe, a shade, a support, a circular collar in said support, bayonet slots in a portion of said collar and pins-in said shade for loosely suspending said shade, a flanged ring supported insaid collar, and means on said flanged ring ior resiliently supporting said globe and shade.

l. A, lighting fixture comprisin a globe, a shade, a support, a slotted circular collar in said support, means in said shade and collar for loosely suspending said: shade, a

ring tted in said collar, slots in said ring cooperating withpins in said collar for attaching and locking said ring, an outwardly extending flange on said ring, and springs on said flange for pressing againstsaid globe and resiliently supporting said globe and shade.

A lighting fixture comprising a globe, a

shade, a support, a circular member support embodying an outwardly extending flange and a. receptacle, means cooperating with said outwardly. extending flange for loosely attaching. said shade, and means comprising a collar and an outwardly e2;- tending'tlange adapted to be fastened and in said locked in said receptacle for resiliently uniting said globe,.shade and support.
