Abstract
A wall mounted lamp in which a bulb can be moved vertically within a shade to adjust its pattern of illumination. The bulb is suspended by its cord from a cane shaped tube, within which the cord is moved by a straight tube, which extends below the fixture for making the adjustment and to keep the cord neat. The lampshade has foil lining, a corrugated paper core, and flexible edge molding, so its covering can be changed easily. A simple plumb-and-distance instrument facilitates installation. Spring brackets keep the mounting snug and resist lifting the lamp off its mounting screws.
