Abstract
Abstract A lamp with an articulated support comprising a stem and a plurality of arms disposed in succession and connected in an articulated manner to each other at intermediate points. A terminal one of the arms remote from the stem supports at the one end a lamp holder and its relative accessories and at the other end a counter weight is arranged in such a manner as to balance the terminal arm and the components supported by it. Each other arm has one end connected in an articulated manner to the next arm in the direction of the terminal arm, and its other end supports a counterweight arranged in such a manner as to balance the said other arm with all the components supported by it.

Claim 1
Independent Claim
233 words
A lamp comprising: a support including a base, and a stem mounted on said base; a transformer on said base; a plurality of arms articulated in succession and including an initial arm and a terminal arm; respective articulations between said stem and said initial arm at an intermediate location along the length of the latter and between one end of each arm and an intermediate location of each successive arm for articulating each arm for independent swinging movement; a lampholder on one end of said terminal arm; a respective counterweight on the other end of each of said arms divisioned and positioned to balance same at its respective articulation location whereby the counterweight on said terminal arm balances the latter and said lampholder and the counterweight on said initial arm balances all of said arm and said lampholders at the articulation location of said initial arm; and electrical conductor means extendi8g between said transformer and said lampholder for energizing an electric lamp received in said lampholder, said electrical conductor means including a pair of parallel spaced conductive rods connected to respective terminals of said transformer and forming said stem, further pairs of conductive rods forming each of said arms, and means electrically connecting each rod of each pair at a respective one of said locations with a corresponding rod of another pair whereby the lamp is electrically energized solely through the conductive rods.
