One of the objects of my invention isto provide simple and effective means for storing the lamp cord and paying it out in such lengths as needed. p

Another object is to enable the adjustment. and setting ofthe lamp indifferent angular A further object toprovide for the supporting of-the lamp on walls and the like surfaces, as well as on tables and such usual horizontal supports.

Mounted on the upper side of the base and preferably seated within a depression 11-, therein is the cord reel, made up in the illustration of a hollow drum 12, pivoted on a screw stud 13 and carrying at its upper at one end at 18 t0 the base and at the other end at 19 to the drum. The reel flanges may r extend out over the as indicated in Fig. .tect the winding spring.

A convenienhand practical method ,of constru'ctingthe reel is to cupthe "central, portions of the two flanges, as indicated in Fig. 1, sothat the cupped portion of one flange will fit inside the cupeon the other flange, the two-cupped porti ing one within the other and; constituting thetdrum portion of the reel. The flanges edges ofthe depression,-

In-the illustration-these ratchet teeth are out i flange The ratchet'teeth are faced-so as: to permit the unwinding movement of the reel by simply pulling on the cord, the spring- 1- so as to cover. and pro- Fig. 4 is a detail sectional view nsf-thus nestunderside of the top or cover 2350f the-base '10s in the rim of reel vsisting in the illustration, :working through thecover of the base and serving b'y engagementwiththe pawl (F g.

The lamp is-made capable of being sup.-

s erving to draw the post firmly down in its socket and to engaged with each other.

The socket is preferably made angularly, adjustable on the post, as by mounting it on a ring 42, held clamped by a screw bolt fastening 43 between clamping jaw portions 44 at the upper end of the post. This conthe lamp socket being tilted over at an angle and this, with the rotatability of the post provides for the setof the lamp in practically any angular relation, the clamp at 43 and the springholding device 40, serving to maintainthe ported on'walls and the like by providing it with .a suction cup supporting device 45 normally housed inarecess 46 in the bottom of active extended position by a, lever 47 to be received'at 48. This lever base and working in a slot 50 extending across the base to the suction cup recess 46 at the opposite edgethereof. The suction rupis normally held in the withdrawnim active position by a spring 51 acting on the of a button 25,.

T he suction cup 15 used by simply operating on the extended handle portion 53 of the lever so as to project and force the cup into engagement with the wall or other surface. This securing device is also of use when it is desired to secure the lamp in a certain position on a table or other support. J The lamp is usually equipped with a suitable shade 54, and to hold thisshade in place in all the tilted and various angular 'posi;

- tions of the lamp, I have provided a special holderconsisting of a yoke-shaped memdoubled upon itself tovembrace the tip portionof the lamp 5'6 and having arms '57 cut outfrom the top and sides thereof and bent radially outward to form outstanding supports engaged with the shade at 58. The. cutting of the shade supporting arms frO'mthe sides of the yoke, leaves these sidesv portions 59 which can befit thelamp andwhieh act as spring-holding arms. f The invention, it will be seen, is of simple and inexpensive construction and by reasonof its adaptability to different conditions, has a wide range of usefulness. 1
