LAMP-GLOBE FIXTURE.

Specification of Letters Patent.

Patented July 13, 1915.

To all whom it may concern:

Be it known that I, CHARLES BERTRAM, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Lamp-Globe Fixtures, of which the following is a specification. I I

This invention relates to lighting fixtures and comprises particularly a device for suspending the lamps and shade of an electric fixture employing an inverted shade or bowl, especially suspended by chains. However, the invention is not limited to any particular embodiment, but may be employed in structures of'various types.

The fixture avoids the necessity for drilling holes in a shade, and also provides means for suspending bowls of various sizes from the same fixture.

The structure comprises a spider or spac-- detail of a modification.

Referring specifically to the drawings, 6 indicates the inverted bowl or shade, and 7 the suspending chains, of which three are ordinarily used. In the form' shown in Fig. 1 the shade is provided at its rim with an inwardly projecting flange 8 which is engaged bythe supporting devices. Each of these devices consists of a finger 9 which projects from a stud or body 10 having an eye 11 at the top, to which the chain 7 is connected. This body is bored transversely to fit on one of the spider arms or rods 12,

which may be made of heavy wire, and the device is adjustable along the arm to any .desired position, being fixed at adjustment by a screw 13 tapped into the stud and bearing against the rod. The end of the rod may be cut ofi' if it is too long for the radius of the bowl. The stud also has an angular depending threaded nipple 14 on which the lamp socket 15 is screwed, this nipple being so disposed that the lamp bulb will extend electric wires which, as usual, are led down the chain. The arms or rods 12 project from a central block 17, and they are stifl' enough to space or hold the engaging devices in position under the flange of the bowl. 1

It will be seen that the lamps and the shade may be readily hung, by screwing the lamps on the nipples, and by shitting the blocks or studs outwardly on the arms until the fingers 9 catch under the flange of the shade, the studs being then fixed by set screws 13. This is much cheaper and better than drilling holes in the shade, which often breaks an expensive shade.

In the modified form shown in Fig.'"3 the shade has an outwardly extending flange 20 which is engaged by an ornamental hook 21 projecting from the stud or block 10 and extending over the rim of the shade. The same spider is used in either. form, and the blocks are fastened thereon in the same way.

The spider is concealed within the shade, and the rods 12 are so small the objectionable shadows are avoided, especially as the lamps are held below the spider.

What I claim as new is:

1. A lamp fixture comprising a spider, blocks on the spider arms having projections adapted to engage and support a shade and also having means to support lamps within the'shade, and suspending devices connected 0 to the blocks.

2. A lamp fixture comprising blocks having projections adapted to engage the rim of a shade and also having nipples to receive lamp sockets, a spacing device connecting said blocks, and suspending devices connected to the blocks.

A lamp fixture comprising a spider, blocks mounted on the arms of the spider and having fingers to engage and support a shade and also having depending nipples to receive lamp sockets, and suspension devices connected to the blocks.

,4. A lamp fixture comprising a spider,

blocks mounted on the erms of the spider, In testimony whereof, I aflix my signature each block having a pr0]ecti0n to engage a in presence of two Witnesses.
