Abstract

Improvements in the construction of devices for lampholders of adjustable height that are essentially characterized by the fact of forming the former by providing a box of insulating material of variable configuration and dimensions within which a pulley is set rotating determined by two metal discs properly insulated each one on which the electric conductors are wound, placing inside the pulley itself a spiral spring linked at one end to it and on the other to a fixed part of the general box acting the metallic discs of the bridge pulley between the conductors and brushes that rub on those discs and that are connected to the power supply network or the corresponding lampholder.
