The invention relates to lamps and particuexact construction and arrangement shown and larly stand lamps employing shades. The shades described, but in the claims hereinafter set forth, preferably used are those which are round and I intend to cover all modiiications and variations circular, having open tops and bottoms and made of the invention.

relatively long iluorescent lamp tubes. 'I'hese fluorescent lamp tubes being generally of great length, as for instance 18,'24 and 36 inches, and being supplied and fitted with permanent end contacts may be utilized in the ordinary lamp shades if angularly disposed within the shades as shown in the drawings and described herein. If properly installed within the shade at the proper angles, the ends of the uorescent tubes at the bottom portion of the shades should not be seen, thus causing the lamp stand to present a good and desirable appearance. As shown in the` drawings, there is a set of three iiuorescent lamp tubes a, b and c. Each of the lower 'ends of these fluorescent lamp tubes a, b and c are mechanically and electrically connected with two sets of arms or supports u, v and w, respectively and y and a, respectively. The outer ends of the supporting arms u, v and w are connected to the lower ends of the fluorescent lamp tubes a, c and b, respectively, as best shown in Figure 3 of the drawings, through the Imedium of the lamp sockets and connectors I 6,V

I'l and I8, respectively, 'Ihe shade supporting arms are shown at d, eand f.

As also shown in the drawings, the upper ends of the fluorescent lamp tubes b, c and a are mechanically and electrically connected with the second or upper set of supporting arms at, y and z, respectively through the medium of the lamp sockets and connectors i9, 20 and 2|, respectively.

'Ihe fluorescent lamp tubes, the arms or supports, and thelamp sockets and connectors are all formed carefully and properly so that each of the members of the arrangement will fit together and be connected in the enlarged portions 22 and 23 ofthe lamp standard.

In Figure 5 of the drawings the ornamental casing for one of the lamp sockets and connectors is shown at 2l. Within this casing the connection of an end of` one of the fluorescent lamp tubes and an arm or support is made. Two electrodes 25 and 26 extend from the end of the iiuorescent light tube, and these electrodes extend into sockets 21 and 28 respectively into a. corresponding connector. Each end of each ucrescent light tube is supplied with a pair of electrodes to t into a corresponding pair of sockets embodied in its correspondingconnector.

It will be noted, particularly from an inspection of Figures 2 and 3 oi.' the drawings. that the lamp sockets and connectors are in inverted positions. The lamp sockets and connectors for the upper ends of the fluorescent tubular lamps extend downwardly from the top supporting arms,

and the lamp sockets and connectors for the lower ends of the fluorescent tubular lamps ex tend upwardly from the lower supporting arms. This placement and adjustment oi' the lamp sockets and connectors in the inverted positions shown, together with the angular arrangement of the relatively long fluorescent lamp tubes, and with the double' set of extending supporting arms with Vtheir angular arrangement constitute important features of the present invention.

No claim is made in the present case to the identicalcnstruction of the fluorescent tubular lamps nor the lamp sockets or connectors -as vthey are the .products of another manufacturer and are merely utilized in applicants construction in connection with a modern form of lighting to aid in the use and disposition of the familiar type of lamp shade.

Il In view of the fact that the fluorescent light tubes and the sockets as to their specic construction are not claimed, it is not believed that any specific disclosure beyond what' has been made in the drawings or the specification is I'leCeSSSaIy.

The lamp of the invention is Wired completely i for electrical operation and hascurrent flowing through the wiring 29 and is controlled by the switch 30. The wiring diagram is shown in Figure 7 of the drawings. It is not believed to be necessary to describe the switch, the fluorescent lamp tubes and the transformers in detail, but it will be seen from the diagram that when the switch arm 3| is moved to make contact with the contact point 32 current flows through the transformer 33 and illuminates the iluorescent lamp tube a. When by means of the switch operating arm 3| contact is made with the contact point 34, current continues to ilowthrough the iiuorescent lamp tube a and its transformer 33, and valso through the transformer 35 and illuminates the iluorescent tubular lamp b. When the switch arm '3| is moved further and contacts with the contact point 36, current continues to ilow through the fluorescent tubular lamps a and b and their respective transformers 33 and 35,

and also through the transformer 31 and illumi nates the fluorescent tubular lamp c. At this .time it will be seen that each of the fluorescent .tubular lamps a, b and c are illuminated.

In order to cause the current to cease flowing through the nuorescent tubular lamps, the switch arm 3| is moved out of contact with the contact points 32, 34 and 36.

Having shown and described my invention what I claim and desire to secure Patent of the United States is:

1. A lamp construction including a lamp standard, a lamp shade, elongated lighting tubes having a length materially longer thanthe height of the shadef means for mounting said tubes on the upper end ofthe standard, said means comprising an upper and lower series of arms mounted on the standard within' the confines of the shade for supporting the ends of the lighting tubes, the supporting ends of the arms for each-tube being out of vertical alinement with each other, said lighting tubes being angularly supported within the limits defined by the-dimensions of the shade by Letters and each tube crossing'the standard within the 5' out of vertical alinement with the arms of the f lower series whereby the lighting tubes are angularly supported within the limits defined by the dimensions of the shade and each tube crossinfg Y the standard within the confines of the shade.

3. A lamp construction including a lamp standard for use-with a lamp shade and comprising an upper and a lower series of' outwardly extending arms carried by said standard, a socket carried on each arm for supporting an elongated lighting tube between the two series of arms, said lighting i tubes being materially longer than the height of the lamp shade,.the` upper series `of arms being Y out of vertical alinement with the arms of the lower series, the sockets of the upper series of arms supporting the tubes being out of ,vertical member having two series of outwardly extending:r

'arms attached thereto, said arms supportingv a alinement with the sockets of the lower series of arms supporting the same tubes wherebythe lighting tubes are angularly supported within the limits defined by the dimensions of the shade.

4. A lamp construction including-a lamp stand-- ard for use with a lamp shade and comprising an upper and a lower series of outwardly extending arms carried by said standard, a socket connector carried on each arm for supporting an elongated lighting tube between the two series of arms, said lighting tubes being materially longer than the height of the lamp shade, the upper series of arms being out of vertical alinement with the arms of the lower series, the sockets of the upper series of arms being out of vertical alinement with the sockets of the lower series of arms, said socket connectors being angularly positioned with respect to the arms and at right angles to the elongated lighting tubes whereby the` lighting tubes are angularly supported within the limits series of. uorescent tubular lamps, the ends of the individual fluorescent lamp tubes being connected to the ends of the two series of lamp tube supports, said fluorescent tubular lamps being angularly disposed and arranged about the top portion of said upright member, one series of lamp supporting 'arms being oiset from the other series and not in direct alignment with it, said uorescent tubular lamps and said supporting arms being mechanically and electrically connected at their terminals, plugs secured to the ends of said uorescent tubular lamps for making the connections and sockets secured to the ends of the two series of supporting arms extending from said upright member, said series of plugs andy socket connectors .being in inverted relationship, the connectors at the top portions of the fluorescent tubes extending upwardly from the ends of said tubes and the connectors at the bottoms of saiduorescent illuminating tubes extending downwardly from the bottom ends` of said uorescent illuminating tubes.
