Feb. 18, 1941. LUDWIG 'STAND LAMP ASSEMBLY Filed March 18, 1940 INVENTOR. Saule uw Patented Feb. 18, 1941 PATENT OFFICE 2,232,464 STAND LAMP ASSEMBLY Louis Ludwig, Brooklyn, N. Y.

Application March 18,

' 5 Claims.

This invention relates to stand lamp assemblies, and lmore particularly .to assemblies of shades, lamp-supporting brackets, and supports therefor.` The prior usualpractice has been to solder the shade to thesupport in order to prevent the shade from turning with reference to the support.

The objects of the present invention, among others, are: To provide an improved lconstruction of assembly for a lamp shade, a lamp bracket within the shade, and the end of a support; the support maybe hollow and contain electrical wiring, which may pass thru the hollow .end of the `support and thru holes in the Shade and the lamp bracket and the `wires suitably connected to the terminals of a standard electric lamp socket.

In one embodiment of the invention the lamp bracket has a flat arm, apertured near the end and engaging the inside of the back of a shade, `a shade having a at back and centrally apertured, a hollow'ilexible supporting arm, a hollow nipple internally threaded at the outer end and secured against turning` on the flexible arm, lugs on the bracket arm projecting outwardly adjacent the aperture in the arm, extending thru the aperture in the shade and into recesses formed in the vend of the nipple, and .protrusions on lthe bracket arm on opposite sides of the arm aperture which extend into apertures on opposite sides of the shade aperture, and a hollow arm adapted to thread into the nipple threads and having Secured on the end a hexagonal head the Wall of which holds the assembly tightly together so that all of the assembled .parts turn as a rigid unit with the end of the flexible supporting arm. In another embodiment of the invention the same rigid assembly connection is mounted .on the end of a hollow swivel which is supported on the side of a vertical supporting arm at the top. In an alternate assembly structure the hollow Swivel or nipple end has opposite end recesses, the .bracket arm has the same outward lugs, but the shade has slots on opposite Sides -of its central aperture thru which the .arm lugs extend into the recesses in the end of the nipple, swivel, or other base support, in which case the arm protrusions and the apertures'in the Shade into which they are adapted tofit may be omitted.

Other objects will appear as the description proceeds.

Reference is made to the drawing in which Figure 1 isa front-view with a front section of the shade broken out.

Figure 2 is a section on the line 2 2 of Figure 1.

'Figure 3 is a` section on the line 3-3 of Figure 1.

Figure 4 is a view like Figure 2 but enlarged and showing a swivel support.

Figure 5 is an enlarged transverse section thru the assembly and swivel support.

Figure 6 is like Figure 2 but showing an enlarged alternate assembly Structure.

Fig-ure 7 is -a transverse section thru the assembly shown in Figure 6.

A shade I0 has a substantially at, circula-rly apertured approximate the center, back wall. A standard electrical lamp socket II has the usual internal screw threads and is adapted to mount an electric lamp (not shown) within the shade Ill, and is itself supported -on one arm of a rightangled bracket I2 which has an aperture for admission to the socket II of electrical wiring I3 which also passes thru an aperture I4 in the arm and into the socket II. The long arm of the bracket I2 is flat and lies against the inside back wall of the shade I IJ, and near the end has an aperture concentric with the aperture in the rear wall of the shade I0.

Referring to Figures 1, 2, 4and 3, a base I5 may have a conduit for the electrical wiring I3 and supports a hollowlexible arm I6, on the upper end of which is Secured .a hollow .internally threaded nipple I'I, the outer end I8 of which is pressed upon the exible arm IIS so as to securely grip it against turning thereon. The end of the nipple I"I is flat, lies against the outside of the back Wallof the Shade I0 around the aperture, and has two diametrically opposed recesses I9 therein. Projecting outwardly from the long arm of bracket I2 at the edge of the end aperture therein are two diametrically opposed lugs 2l adapted to snugly fit in the recesses I9. On opposite sides of the aperture in the long arm of .bracket I.2 are :outer ,protrusions 22, spaced 90 degrees from the lugs '2I, which enter apertures in the rear wall of the shade I0. A centrally apertured hexagonal nut 523 is wider than the .aperture in the long arm of the bracket I2 and heads the end of a hollow screw 24, the threads of` which engage lthe internal threads of the nipple I'I, and when the nut 23 is tightened the nipple I1, the shade I0, and the bracket I2 are locked together and against relative rotative movement; It will be noted that the assembly is easily and quickly made.

Referring to Figures 4 and 5, a rigid hollow supporting arm 25 supports near the top a lateral projection 26 on which is mounted a hollow swiveled nipple 21 externally roughened for facile manual rotation, internally threaded, and having diametrically opposed. recesses 28 like the recesses 2l. The assembly is the same as that shown in Figures l, 2, and 3.

Referring to Figures 6 and rl, the outer protrusions` 22 are omitted from the outside of the bracket I2 as are also the corresponding apertures in the shade I0. Instead of the former construction diametrically opposed slots 29 are provided adjacent the shade aperture and the bracket lugs 2l are passed thru slots 29 to hold the shade I0, the nipple Il, and the bracket arm I2 together against relative rotation when the screw 23 and the nut 24 are tightened.

Having disclosed my invention and realizing that, in View of my disclosure, many changes or omissions or substitutions of parts will readily occur to those skilled in the art, I do not limit myself to the exact structure shown and described.

I claim:

l. In an electrical lighting fixture, a substantially flat apertured member, -a second iiat member engaging one side of said apertured member, an arm having an end engaging the other side of said apertured member, a recess in said arm end, a lug mounted on said second member and extending into said recess and securing said second member and said end against relative rotation, and means for locking the assembly together.
