LAMP.

ap'pncatioa fixed april 2i,

This invention relates to lamps in genera-l and particularl to floor lamps j One of the o jects of thisAv invention 1s to provide a combination iloorlamp and rest support or table.

Another object of my invention is to provide with such a floor lamp adjustable means for ermitting the heightening and lowering oft e lamp stand.

Another object of my invention is to provide in connection with the lamp an adjustable shade support which may be swung 1n a vertical plane so that the lamp shade may be set either symmetrically to the lamp stand or to one 'o r the other side thereof. j

Anotherobject of my invention is to provide in connection with the adjustable stand means for holding the adjustable parts in desired relation to each other.

The foregoing land further objects will be more fully apparent from the following description and the accompanying drawings forming part of this disclosure 1n whlch,

Figure 1 is an elevation of my device shown in one of its preferred foi-ms.

Figure 2 is a crosssectional view through i my device.

Figure 3 is an enlarged detailed view of my locking device associated with the adjustable members of the lamp. A

Figure 4 is a detailed view of the lamp i shade in section showing the shade support or holder in two positions and,

Figure 5 is a cross sectional detailed view through the adjustable element by means of which the shade support may be set into desired osition. Re erring to thedrawings numeral denotes the base of my lamp, stand to which is pgrmanently attached a hollow tubular mem-- r 11.' lAssociated with that member 11 is a rest member 12 which maytake t-he s hape of either a rest, a table, a cabinet, 'as for instance for radio use, sewin utensils, etc. i Extending above t e rest member is another tubular member 13 and extendin from this member is another tubular meinl er 14. To tubular member 14 is attached in. any desired manner a casing 15 in which is adjustably mounted a frame 16 serving las support of shade 17.v

It will be seen in Figures 2 and 4 that the shade is attached b .means of brackets'lS to frame 16 and the rackets 18 are rotataby mounted tothe horizontal portions of frame 16 terminating into lamp sockets 19. Frame 192s. serii No. 103,438.

16 is composed of tubular members which are joined by means of a (yoke 20v (see Figure 5). Yoke 20 is provide with a threaded aperture to receive a clamping screw 21 provided with a knob 22. The frame members 16, composed of tubing for receiving the electric wire passing to the sockets 19, are rotatably lodged at 23 in the walls 24 of the casing.

The cover 25 of the-casing is provided with the transverse slot 26 in which clamping screw V2l may be freely swung 180 in a vertical plane. By tightening the knob 22 against the cover member 25 the frame members 16 may be set to any desired position as clearly seen in Figure 4 where shade 17 isshown in its symmetrical position relative to casing 15 in full lines while the broken lines indicate the posliion of the shade when vswung 90 to the ri ubular member 14 telesco es with tubular member 13 and tubular mem er 13 telescopes with tubular member 11. 'For the purpose of adjusting and setting the respective tubular members in desired position, a clam ing device as shown in Figure 3 in detai is provided.

In principle it consists of a conical member 27 which is referably split and is adapted to enga e wit its inner surface the smaller mem er 13. A cap 28 threaded internally rest support 33 hold rest mem er 12 in de?,v

sired relation to tubular member 11. 4 y

For the purpose of permitting the adjustment of the various tubular telescoping members 11 13 and 14 the cable 34 is wound into spirals, a large one indicated at 35 in memown tight, the

so -V ber 11 and a lsmaller one indicated. at 36 in tu- ,bular member 13.. ,The cable is securely held' within insulations 37 and 3.8 withinl these members. For the purpose of guiding the telescoping members by each other and yet permitting a fairly loose movement when desired and at the same time insulating the cable 34 from the tubular members, l preferably provide an insulating tube indicated at 39 between the tubular members as shown in Figure.

It is evident that a device as described abovey is not only an ornamental piece of furniture but a very practical appliance capable of be- 'ing used 1n many different ways My device i is capable of being collapsed to a height corv responding to the interior of a chamber into which it is to be placed.

For the purpose of reading the shade may be 4tilted to any desired position. If it is `desired that the light be lnearer to the reading matter the upper portion of the device may be lowered accordingly. On the other hand' if it is desired that the light be more spread in the room in which the lamp is placed, the stand may be extended very high. Its universal use makes my lamp a desirable piece of furniture besides its having highly decorative qualities.

'Having described my invention I claim:

In combination with an adjustable lamp,'

including telescoping members and a table su ported by one of said members, an adjustab e shade support, associated with another of said members and comprising a hollow casing provided with a centralslot, a rotary element lodged in the Walls of said casing, a clamping -member engaging said rotary element an passing through theslot of said casing, and

adapted to engage the latter when said rotary 1 April A. E. 1926. y
