Application fi'led April '23,

' the wires, thus causing. short circuits with their attendant dangers.

Y My means of accomplishing the foregoing object may be more readily understood by having reference to the accompanying drawings, in which' A Y Fig. 1 1s a vertical, sectional view of my.

improvement; and t Fig. 2 1s a side elevat on of the same. Similar reference numerals refer to S111l1 lar parts throughout the entire description.

As shown in the drawings, the fixture I stem 1 extends from the fixture (not shown),

and has mounted atits outer end 2, my 1mprov-ed housing 3. This housing is formed of a cylindrical t be in which is located a standard socket shell 4 which is provided with the usual standard sleeve 5 formed of suitable insulating material. Within the tube 3, at the point of entrance of the stem 1, I mount a section of tubing6 which has a very thick or heavy wall, which is provided with 'a threaded opening 7, into which the threads on the end of the stem 1 maybe screwed. Y 'To those skilled in the art, it will be apparent from the foregoing description'that this construction provides a thickness for the support of the housing, which is not to be found inthe ordinary housings, and hence possesses unusual strength at this point.

The lower end 8 of the tube 3 is closed by a disc 9 having a central aperture 10 which forms a convenient pull in box for the electric wires (A) and in which is mounted an upwardly extending stem 11 formed on a plate 12 and fitting the threaded portion of the hickey 13 ofthe socket shell 4;. The rotation of the socket 4 is prevented by means of a small screw 14 which passes through a threaded hole 15 and extends into a hole 16 formed in the disc 9, though any other suitable means for this purpose may be employed.

such as tight or twisted corscribed will present 'tirely avoid the usual stem joins it,
