IFLOOR LAMP.

Application filed November 10, 1924.

My invention relates to the art of electric lighting fixtures, and, particularly, to that class that is commonly known as floor lamps in which a bridge arm is used to suspend the lamp at a distance from the supporting standard. r

The object of my invention is to provide such a connection between the supporting standard and the bridge arm as will permit of the vertical adjustment of the positioning of the bridge arm in a simple and easy manner. A further object is to provide such a supporting connection for the bridge arm as will permit it to be easily and quickly rotated laterally to any desired position.

I am aware that floor lamps of this character provided with means of the vertical adjustment of the bridge arm on the standard, have been in use for quite some time, but the effecting of the movement of the arm vertical and the securing of the supporting member in the proper position on the standard so that it will not slip or change its position has been most unsatisfactory, and required considerable time and effort to make the adjustment, and the same could only be accomplished by the use of both hands of the operator. It is, therefore, my purpose to remove these objectionable features, and provide a device of this character which will make such adjustment an easy matter, and it may quickly be performed by the use of one hand.

My invention consists of certain details of construction set forth and pointed out inv my claims and illustrated in the accompanying drawings, in which- Fig. 1 shows a side elevation view of a bridge arm, my improved connection, and a portion. of a'supporting standard, the light, socket, and shade being shown in dotted lines;

Fig. 2 shows a side elevation view of my device, the bushings and rotatable member being assembled;

Fig. 3 shows a longitudinal section of the same; and

Fig. 4 shows a side elevation view of the rotatable member of my fitting, separated from the bushings.

Referring to the accompanying drawings,

serial No. 748,846.

the reference numeral 10, is used to indicate the supporting standard of a floor lamp, a fragmentary portion only being shown, as obviously, the particular floor lamp used is no part of my invention; 11, the bridge arm SUSpBi1Cl8Cl therefrom; 12, the light, socket; and 13, the lamp shade. The bridge arm, 1.1, is securely attached to a rotatable member 14, which surrounds the supporting standard 10, the inner wall of the member 14- being slightly spaced from the standard.

A. bushing 15, is secured to the upper portion of the member 14, and extends upwardly therefrom. Another bushing 16, is secured to the lower portion of the said member and extends downwardly therefrom. These bushings 15 and 16, obviously surround the supporting standard, and are each provided on their inner surface with a felt pad 17 and 18, respectively, the construction of the parts being such that the felt pads securely grip the outer surface of the supporting standard 10. Although I have illustrated and described these pads as being made of felt, it will be understood that any elastic or compressible material may be used.

The bushings are secured to the member 14, in any desirable manner which will provide for the rotation of the member 14, within the bushing. i

In my drawings, I have shown a horizontally disposed recess at the lower and upper parts of the rotatable member and extending inwardly from the outer surface thereof, said recesses being identified by the numerals 19 and 20, respectively.

The bushings 15 and 16 are made of the proper size to slip over the ends of the rotatable member, and. a tool. is then used to seat the overlapping wall of the respective bushings in their respective recesses, so that the result is as shown in Figure 3.

Obviously, the connection to provide for the rotation of the rotatable member 14 within the bushing, may be accomplished in any manner, or, even the bushings may be so constructed that they may spring over their respective ends of the rotatable member and seat themselves in the recesses or depressions, so as to properly grip the rotatable member.

I, therefore, do not desire to be limited in my protection to any specific construction for this purpose, except as set out in the appended claims.

I provide'an entrance orifice 21, in the bridge arm 11, for receiving the current carrying Wires (not shown).

The operation of my device is as follows:

- The bushings 15 and 1G, constructed in the manner hereinbetore described, are of the proper size to closely lit the outer Wall of the supporting standard 10. I

The felt pads 17 and 18, provide the proper amount of resiliency, as Well as gripping surfaces, thereby making it possible to easilyslide these bushings up and down on the standard, but, unless forced up or down, they Will remain in the position placed, firmly and securely gripping the standard 10.

While these members are gripping the standard, the rotatable member 14 is free to move laterally for positioning the lamp at any desired angle surrounding the standard.

Having thus described my invention what I regard as new and desire to secure by Letters Patent of the United States is:

1. A device of the character described, comprising a supporting standard, a pair of bushings on said standard, a member intermediate said bushings in spaced relation to the standard, said member being loosely secured to said bushings whereby it is free to rotate on the standard without moving said bushings, elastic and compressible material intermediate the standard and the bushings. 2. A device of the character described, comprising a supporting standard, a bushing on said standard, a member secured to said bushing, said member being loosely secured to said bushing whereby it is free'to rotate on the standard without moving saidbushing, elastic and compressible material intermediate the standard and the bushing.
