Application August 6, 1945, Serial No. 609,077

1 Claim.

The invention relates to light fixtures and particularly to lamps having a base, a post and a head carried on the post.

Lamps and particularly oor lamps present a shipping problem by reason of the fact that even in large cartons only a few lamps can be packed because of the size of the base and the narrow diameter of the post.

The present invention, therefore, aims at providing a floor lamp where the base may be readily removed without disturbing the electric wiring passing from the head through the post and emerging from the base without the use of washers or lock nuts.

A further object constitutes the provision of a :door lamp wherein the base is constructed to permit removal thereof without necessitating the removal of the electric plug and leaving the wiring intact.

With these and other objects in View which will become apparent from a perusal of the invention, the latter comprises the means described in the following specification particularly pointed out in the claims forming a part thereof, and illustrated in the accompanying drawing, in which Fig. l is an elevational View of a oor lamp in which the invention is incorporated.

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 3 3 of Fig. 2.

Fig. 4 is a view similar to Fig. 3 with the parts in disassembled relation, and

Fig. 5 is a top plan view of a base.

Referring to the views of the drawing, the lamp comprises a base I to which is secured a post generally designated by I I carrying at the upper bend a lamp head not shown surrounded by a shade I2.

The post Il comprises a tube i3 surrounding an inner pipe I4 which is provided with threads I5 at the lower end. The pipe I4 is threadedly engaged in a threaded. aperture I6 in the base formed at the top with three openings I8 of standard construction whereby a plurality of spokes I9 are formed.

The base is surmounted by an insert or cover 2u and an ornamental break 2| is interposed between the tube I3 and the insert. These elements are further secured by a lock nut 22 against accidental turning.

The wiring 23 leads from the lterminals of the sockets through the pipe I4 and base and is provided with a plug 24 for insertion in a wall socket of a home to supply current to the lamps of the head.

The parts thus far described are standard construction oi floor lamps and per se do not form a part of the invention.

The shipping of lamps of this type is quite expensive as only a few lamps can be packed in large containers since the head and post are considerably smaller in diameter than the comparative large and heavy base.

It is for this reason that it is very desirable to enable speedy and convenient removal of the base, so that a larger number of lamps may be assembled in the shipping container and the bases may be packed and shipped separately.

To remove the bases it is important that the wiring and Ithe attached plug shall remain undisturbed so that no expert help is necessary in the removal or assembly of the base.

To this end the aperture I 6 is provided with a slot 25 which places in communication one of the openings I8 in the base with the aperture I6 Thus when the base is to be removed the base is screwed o from the pipe Id, and wire 23 is shifted laterally through the slot 25 into the large opening I8 which is large enough to clear the plug 24, obviating thereby any necessity for removing the plug 24 in order to permit disassembly of the base.

In Fig. 5 a slight modification is shown where the base 30 is solid.

Here the central aperture 3i1 is connected by a slot 32 With an opening 33 which is large enough to clear the plug upon removal of the base.

Attention is called to the fact that the post and head may be assembled and wired as an entity which may be carried out on tables, whereas the assembly of the lamp together with the base requires considerable floor space which is thus eliminated by the invention.

The embodiments of the inven-tion shown in the drawing are merely illustrative of the manner of permitting convenient removal of the base.

Various changes and alterations may be made without departing from the spirit of the invention.

I, therefore, include all variations, modifications and revisions constituting departures within the scope of the invention as defined in the appended claim.

I claim:
