has particular reference ;to an improved lamp base which is constructed and arranged in. such a manner as to housethe extension cord-there- 5 in and permit of the withdrawal therefrom of the required length to reach fromthe lamp to the outlet box. F The invention broadly comprehends a, lamp 1 basestructure including relatively rotatable and 10 axially movable members, one ofwhich carries thelamp socket and a reel secured thereto and the other of which houses the reel and is provided with an opening through which the ,z extension cord extends for effecting; the winding and-una =15 winding of the extension cord-upon-relativerd;

The invention further contemplates means for releasably locking the members of the lamp-base.

structure against relativerotation when the-de .20 sired length of extension cord, has been wound upon or unwound from the reel.

' x As 'a further feature the invention embodies resilient means for disposing \and maintaining the locking means out of'engagement whenthe f 25 same is released so as to permit of-free, relative.

rotation of thelamp base members when winding up or unwinding the extension cord fromjthe reel. v

Other objects of the invention reside-Vin the I 30 provision of an improved lamp base structureof the indicated character hich is comparatively simple in its construction. and mode of operation, inexpensive to produce and asse ble and which is highly efficient for its intendedpurpose .35 With-theabove enumerated and other objects in view, the invention is disclosed in greaterdetail in the followingjs 'pecification andthe accompanying drawing in which: .Fig.'1 is a vertical sectional persp ctive, view in locked'relation. y V

Fig. 2 is .a horizontal sectional view taken approximately on the line indicated at 2-4 of 45 Fig. 3 is a similar viewtaken approximately'on the line 3- 3 of Fig. 1.

Referring to the drawing by characters of reference, the base includes relatively rotatable members designated generally by' the reference 50 characters Av and B. The member" A is composed of a foot l0 adapted to rest upon a supporting surface and provided with an upstanding. central boss I l which is provided with'a socket l2 within which an upstanding pedestal section I3 is ar- 55 ranged.

This invention relates to electric lamps and illustrating. the relativelyrotatable base members '4 Claims; (crass-+ 5)" The pedestal 1 section I3 is, preferably in the form of a-solid rod; the upper end ofwhich is externallythreaded at and has threadedly en gaged'therewith therupper end |,5"of a'downwardly flaring reel section l6, aset screw l1 serv- .5. inggto lock the reel section; thereto. An upper tubular pedestal section l8havins an externally threaded lower end. 19 is alsothreadedly; engaged inthe upperend portion liofthe reel section IS in spaced superposed relation to the pedestal sec- 10 tion 13 and -.is-}lockedby' a i set screw 20" against rotation with referencethereto; Anupper reel section 2| is threadedly engaged over the'threads ;l9 of the upperspedestaljsection l8 and islocked ,againstrrotation with reference thereto'by a set 15 screw 22.

The upper end of the pedestal section l8 has securedthereto a lamp socket 23 with which the wires of the extensionrord extends downwardly through the pede'stal 1 section?

Thelower pedestal section I3 is secured within the socket I2 of the boss of :the foot l0 against rotary oraxial movementby means of a plurality of radial. studs 25 which are threaded through the boss [I l'. and have theinner. pointed terminals 26 thereof engaging in depressions '21 formed in the pedestal section I 3.

.The upperportionof the boss ll above the studs- 25, is ,of. .reduced diameter. tcr' define a I shoulder28 the purp'ose of vv'vhiclqiwillbe herein afterset forth.. 1 The member B of the basestructure includes upper and lowermating hollow sections30 and 3 I- which ereremovamy secured together in any desiredmanner such as by the threaded connection 32 and the lower section is provided at its lower portion with a central bearing opening 33 through which the reduced upper end of the boss H extends. The upper section 30 of the member 13 is provided with 'a bearing opening 34 through which, the upper section l8 of the pedestal extends so that the members A andB are associated with each otherfor relative rotation and for axial sliding movement between the shoulder 28 and .thes ocket .23.; The member B is provided with a radial aperture 35 through which the extension cord 0 extends, the protruding portion thereof being provided with the usual plug 36 for connection with a current outlet socket. The member B is preferably provided with suitable handles 31.

Under this construction and arrangement it will be apparent that by lifting the lamp base structure and holding the same by the handles 31, the extension cord 2, spring latch 45 is anchored as'at 4i to'the lower portion of the lower section 3! of the member'B and said spring latch is provided with a keeper opening 32 which is adapted to u'lS anchored as at 44 to the member B and is provided with'a bifurcated 42 registers with one of the opposite direction and to permit of relative rotation thereof.
