ADJUSTABLE LAMP-SUPPORT.

Specification of Letters Patent. P t t d J l 13, 1920,

Application filed December 27, 1919. Serial No. 347,868.

To all whom it may concern:

Be it known that I, MAX KossMANN, a citizen of the United States of America, residing at Brooklyn, Kings county, State of New York, have inventedcertain new and useful Improvements in Adjustable Lamp-Supports, of which the following is a full, clear, and exact description. I

This invention relates to improvements in electric-light fixtures, but more particularly to table lamps, the object being to provide improved means to support the current carrying cord or cable and also improved means 0 adjustably support a bulb and shade there- I will now proceed to describe my invention in detail, the novel features of which'I will point out in the appended claim, reference being had to the accompanying draw.- ing, wherein Figure 1 illustrates a table lamp embodying my improvements;

Fig. 2 is a fragmentary perspective View of a portion of the arm;

Fig. 3 is an enlarged cross section on line 3-3 in Fig. 1; and

Fig. 4 is a fragmentary sectional view, partly in elevation, illustrating the means to connect the arm and swivel- As herein embodied, my improvement consists of a standard or pedestal 5 carrying a.

lamp supporting arm 6 which is both rotatably and vertically adjustable, said arm being maintained in adjusted positions by a set-screw 7. To the free end of arm 6, I attach a swivel bracket 8 carrying a clamp 9 to support a lamp socket 10. The swivel bracket is attached to the free end of arm 6 by a binding-screw 11. The bracket 8 can be secured in an adjusted position by the screw 11. The bracket 8 is rotatable around the axis of the horizontal portion 12 of the arm; hence the rays of light can be directed The socket clamp consists of a split band 13 carrying trunnions' in the form of screws 14 which pass through the arm members 15 of the bracket 8. The clamp 9v is rotatably adjustable within the frame and is held in an adjusted position by the thumb-nuts 16 Byv the combination of the swivel frame 8 and the swivel clamp; 13, I am able to adjust the lamp to suit most any requirement. As the arm 6 is mounted for rotation on the stand 5, the lamp may be moved in a circle around the st'and. The arm 6 can be raised or lowered, as has been stated, thereby pro viding for vertical adjustment. To provide a support for the cable 16, I form an eye 17 in the arm. In other words, the arm 6 will be made of a rod bent over to form the eye 17 The cable 16 will be passed through bly supported by said standard, a set screw carried by the standard to contact with said rod to bind same in adjusted positions, said rod being bent toform a loop intermediate its ends, a bracket carried by the free end of the rod, a binding screw passing through one end of said bracket and engaging the free end of said arm, whereby said bracket can be firmly secured in adjusted positions, and a clamp pivotally supported by said bracket to engage an electric light bulb.

Signed at New York city, N. Y., this 23d day of December, 1919.
