The rod 15 is slidably engaged in the rod 16 through one end thereof and the rods are bent at their free or outer ends rearwardly, as at I1, and
I8. Attaching plates I9 are fixed on the terminal end-s of the portions l1 and 18 for securing the ends of the rail to the desk so the length ofthe rail will be spaced from the desk. The rail II is formed of metal or plastic or other suitable material.
The rods or tubes [5 and I6 are formed with an elongated slot 20 along the length thereof on the inner side or side toward the supporting memhers"!!! and the desk. A plug 2| is carried by one end of one of the bars, as at H, and is formed with a pair of contacts 22 and 24 with which the contacts of a correlated plug 25 are adapted to vided to form continuous extensible contact members in the rail H and are adapted to be expanded when'the bars 15 and I6 are extended and contracted when the rail is shortened. The end-s of the springs 21 are fixed to hooks or eyes 29 I carried by the opposite ends of the rail forming members l5 and 16. The eyes 29 at one end are connected to the terminals 22 and 24 of the plug 2|, and the eyes 29 at the other end are fixed to an insulating plate 30 carried by the bar or tube [5 to insulate the springs from each other and length thereof.
from the rail I I. The springs are disposed adjacent the opening 20 in the members [5 and 16 so that they may be contacted by a sliding con-v tact from without the rail I I.
The lamp-supporting carriage I2 is slidably mounted on the rail II for movement along the The carriage I2 is formed of a flat plate 3| disposed on the inner side of the rail II and extending above and below the rail. A pair of rollers 32 are rotatably supported from the upper end of the plate 3| for engagement with the rail ll.
