' Application filed m 28,

This invention relates -to electric lamp stands orsupports and more particularly, to such stands or supports wherein are provided means for conveniently adjusting the lamp to any desired elevation at the same time that 1 the lamp shade itself may be freely rotated provision of an electric,lampfsupport, the stand of which is verticallysadjustable to varythe elevation of the lamp, this stand being further provided at its upper end with means for permitting the lamp socket to be freely rotated upon an axis making any desired angle with respect to the horizontal.

A still further object of the invention is the provision of a vertically adjustable lamp stand, the upper end of which is connected by means of a flexible tubing to a lamp socket arranged for rotation freely with respect to.

said flexible tubing.

A still further object of the invention is the provision of a stand provided with a lamp socket arranged foruniversal adjustment.

Other objects, and obj pear more fully hereinafter.

' combination, construction, location and relative arrangement ofparts, all as will be described more fully in the following specification, illustrated in the drawings accompanying this specification, and finally pointed out in the appended claims. In the drawings illustrating a preferred form of the invention, 1 1 Figure 1 is a general side elevation of the lamp stand and the lamp and lamp shade supported thereon; Figure 2 is an enlarged vertical cross section through the lower portion of the stand; 7 Figures 3 and 4: are enlarged'cross sections taken on the lines 33 and 4-4, respectively, of Figure 1; and i "11. fJThe upper ends ofthese leaf springs 1 1 sets relating tov de tails and economies of constructionwill ap- PHILADELPHIA, PENNSYLVANIA. v
