ELECTRIC LAMP Filed June 9, 1945 Patented Oct. 18, 1949 UNITED STATES PATENT OFFICE ELECTRIC LAMP Evelyn Dore, Bronx, N. Y.

Application June 9, 1945, Serial No. 598,614

- 1 Claim.

This invention relates to an adjustable electric lamp. The adjustable stands or supporting arms of known construction for electric lamps, possess the drawback that the ball and socket joints and screw bolts limit the movability and are liable to damage the electric leads. It has been proposed to employ braking and sliding devices as means for securing adjustable stands in the adjusted position, but they possess the drawback that locking screws are necessary which at the slightest vibration change the position, the thread of the screw or nut becoming worn when frequently used.

It is therefore the primary object of the present invention to provide a floor or table lamp which can function as either an ordinary table lamp with comparatively easily adjustable incandescent lamps, or as a floor lamp which has a highly attractive appearance and which looks more like an ornamental luxurious lamp rather than like a utilitarian adjustable lamp that combines two lamps to one.

Another object is to provide a lamp which performs the various functions above enumerated without requiring much space and without necessitating a freakish or unconventional appearance.

Yet still another object of the present invention is the provision of a device of the character described which is light in weight, simple in construction and inexpensive to manufacture, so that it can be sold at a very reasonable price.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or without the scope of the appended claim and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawing:

Figure l is a front elevation of a preferred embodiment of my invention;

Figure 2 is a side elevation of the same; and

Figure 3 is a detailed sectional view on the line 33 of Figure 1.

Similar numerals refer to similar parts throughout the several views.

In the drawing the numeral l denotes a base which is preferably hollow and conical, and from whose center extends upwardly the lowest telescope member of a hollow center post that can be telescopically expanded as indicated in Figure 1 in dash-and-dotted lines. A head 4 is secured to the uppermost telescope member 3, and curved figures 5 (which are S-shaped in the instance shown) are laterally secured to head 4 and are connected to each other by means of an ornamental oblique cross-bar 6. An electric lamp having a shade and a switch is carried by the top portion of each figure 5. The figures 5 are hollow and their outer portions are provided with slots [0 One or more coiled cables I l, which are provided with a contact plug it 4, are extended through base ll, through the telescopically expansible center post (2 and 3), through the figures 5 and through the T-shaped members 9.

If the center post parts 2 and 3 are in the position shown in Figures 1 and 2 in full lines, the lamp can be used as a table lamp; if the center post is expanded, as indicated in dash-and-dotted lines in Figure 1, the lamp can be used as a floor lamp.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent in the United States is:

In an electric floor and table lamp, the combination of a hollow, telescopically expansible center post having a hollow base at its lower end and a head at its upper end; with two curved T-slotted tubular members laterally extended from said head and carrying electric lamps at their top portions; and T-shaped members slidably engaging the slotted portions of said tubular members and carrying electric lamps which are connected to a source of current by means of coiled cables that are extended through said base, centerpost, head, and figures.

EVELYN DORE.
