I trenrrnenmr' 5 Application filed June s,
- My invention relates to lighting units and has particular relation to a Supporting device for such units.
Lighting units have been devised whereby the sockets, the lamps'and the globes are so arranged and supported that the globes may be removed from the supports without dis turbing the sockets. Generally, they globesv of such lighting units are provided with cylindric'al openings in their upperv portions,
} and the supporting'stand ardsrare provided with two or more projecting fingers to sup- 7 port the globes by projecting beneath suit able flanges of the gl obes. When the globes are in engaged position, supporting canopies or like membersrest uponthem to prevent them from tilting and from being disengaged from the supports.
However, such devices are so constructed that the globes are not easily removed by a single operator, and consequently, breakage of the globes frequently occurs.
My invention is intended to eliminate these 7 and other difficulties and to provide animreadily be manipulated the globe and disassembly of theunit.
proved supporting device. Therefore, an object of my invention is to. provide a sup-. porting device for a li hting unit which may to permit removal of Another object of my invention is to provide a simple, inexpensive, strong and durable device. a
Other objects of my invention will appear in the following description of my device, taken in conjunctionwith the drawings.
Referring to the drawings, in which like figures indicate like parts, V V
Figure 1 is a side view, partly in elevation and partly in section, of my device, with the globe and canopy in their engaged positions, and
Fig. 2 is a side view, partly in elevation and partly in section, of my device with the canopy in a disengaged position and showing the globe being mounted upon the supporting device. p

Referring to the drawings, the supporting member l is here shown asna tube having a 19 29. seriai 371,765 V the tube or pipe byimeansgofa nipple 4Q and a bracket .5, the'centralportionrof which; en? t gagesthenippleand the'louter'endsofwhich are fastened vscrews6.

:1 If no f rtherstructure werefprovided,"the
globe might eventually become disengaged from the globe support,'so that a canopy 14, which is'preferably of bell-shape and has. a lower flange 15,- is provided with an opening 16' at its center so thatit-maybe sl idably mounted on the standard 1 and may be moved up and down or tilted thereon; When the canopyfisvin itsrlower orengaging position,

globe andsupport In its raised .position',:,-the canopymay be tilted, and the lower edgeof the flange ,15
may be engaged by one oftheprojectio'ns :11
to hold the canopy in its raisedposition'while theglobe'is being removed.
The devices of the-prior ,art have: been so sary' for the operator: to hold the 1 canopy in arranged and constructed that it was neces its raised or disengaged positionwith one support.
It is apparent that other modifications of my device may bemade; for instance, the. support 7, instead of being a flat strip of metal, maybe apmemberof cup shape. Instead of the projections- 11, which-are adapted to coact with the flange 15, projections may be placed on the inside of the'canopy to coact with suitable depressed portions or open- "ings in the support. These and othermodifications maybe made by those skilled in the art without departing fromthe spirit and scope of my invention, as set forth in the ap pended 'claims..
. I claim as -my inventionz 1. A lighting unit including a globe, a
tacle adapted'to be connected to an energiz- 1ng source, a globe having an openlng 1n its upper part for engaging the globe support,
a canopy slidably mounted on the supporting member to hold the globe in place on the globe'support, a locking- "means for holding the .canopyin-its engaged position,-a nd coacting means on the globe support and canopy for holding the canopy in a raised disengaged position."
In testimony whereof, have hereunto subscribed my name this 7th day of June 1929. OSCAR WERNER.
