Gill Attorney-Max R. Kraus ABSTRACT: A mounting for an electrical socket for a lighting fixture whereby the socket is provided with an attachment clip, permitting it to be readily locked with a support bracket of any length, which support bracket is secured to an arm ofa lighting fixture. This arrangement permits support brackets of any desired length to be used to provide the required support length.
BRIEF SUMMARY OF THE INVENTION In providing supports for electrical sockets which are connected to the arm of a lighting fixture, it is necessary that there be carried in stock as standard equipment a unit comprising a socket fixedly attached to a support bracket of a defined length. Since such units require support brackets of various lengths, dependent upon the length of the decorative sleeve, it becomes necessary to carry a large inventory of such units in different lengths. With this invention this is eliminated as the socket comes separate and is detached from the support bracket but has means for the ready attachment thereto of a support bracket of any desired length. Instead of supplying units of various lengths it is only necessary to supply common sockets and supply support brackets of various lengths, which support brackets can be readily coupled to the sockets. This reduces the inventory that has to be stocked and results in appreciable savings.
Other objects will become apparent as this description progresses.

FIG. 1 is a view of a portion of a candelabra utilizing the invention.
FIG. 2 is an end view partly in section, showing the invention.
FIG. 3 is a side view ofFIG. 2.

FIG. 6 is an enlarged end view partly in section.
FIG. 7 is a view taken on line 77 of FIG. 6, and
FIG. 8 is a perspective view of the connector clip.
The invention is herein described in connection with an electrical candelabra fixture, although it is not so limited.
The lighting fixture generally indicated at 10 is supported in a suspended position on a rod, cord or chain 1 .2. The lighting fixture has a plurality of arms 14, only one of which is shown in detail. The arm 14 is tubular and is shaped as best shown in FIG. I, with the outer end 16 of the arm extending vertically and being externally threaded as at 18 to receive the internally threaded sleeve ofa support for a socket and light which forms this invention.
A conventional socket 20 has a flattened surface 22 to which is attached an attachment clip generally indicated at 24 by means of a rivet or other fastener 26. The attachment clip 24, best shown in FIGS. 4, 6 and 8, is formed of metal and comprises a lower portion which is shaped to provide at one end a forwardly extending side 28 and inwardly extending flange 29 which, as best seen in FIG. 7, inclines inwardly toward the back. The opposite side of the clip extends forwardly and inwardly to form with the back a generally U- shaped configuration 30. These flanges form channels 32 and 34 for receiving the upper end of the support bracket, to be described.
The lower portion of the clip has a small tongue 36 punched out which extends forwardly into the recess. The upper portion 38 of the clip has a reduced width and is provided with an opening 39 which is engaged by the rivet 26 previously described. A vertically extending reinforcing rib 40 is provided. The clip 24 is secured to the socket so that the lower end of the clip extends below the bottom of the socket and extends inwardly thereof, as best seen in FIG. 6.
The supporting member generally indicated at 42 includes a flat support bracket 44 formed of metal, of generally rectangular shape, the upper portion of which is provided with an opening 45. The upper portion of the support bracket is inserted in the channels 32 and 34 of the clip and as the opening 65 in the support bracket passes the tongue 36 it locks therewith ermanently so that it cannot be detached therefrom. be inclined front flange 29 urges and maintains the support bracket in close contact with the tongue 36 of the clip. The lower end of the support bracket 44 has an internally threaded sleeve 46 with a bottom flange portion 48.
In mounting the holder on the arm, a dish-shaped member 50 with its central opening 51 is positioned on the end of the arm M to rest against a head 52 on the arm. The internally threaded sleeve 36 of the support bracket 44 is threaded to the threaded end 118 of the arm 14 to hold the parts together so that the socket is supported. A light bulb 54 is supported in the socket 20 and a decorative sleeve 56 is positioned around the socket 20 and support bracket 44 and rests in the decorative dish 50. The conducting wires 58 from the socket extend through the decorative sleeve and into and through the arm of the candelabra and are connected in the conventional manner to the current supply.
