one of two highly sought after original hard to find antique american industrial "white" articulating arm wall mount task light designed and fabricated by the otis c. white company, worcester, mass. at the base of the fixture, attached to the wall or column, is a sectional ball and socket joint, carrying a metal tube, in this case four feet long; this tube at its other end by an adjustable swivel joint carries a second tube (three feet long) which holds the lamp and shade by an adjustable patented wrist joint. this combination of joints allows a range of motion even more extensive than the movements of the human arm, with its three joints at shoulder, elbow and wrist. the upper and lower arm can be lengthened or shortened at will and held firmly in the exact position in which it is placed. the various joints hold their positions by friction of scientifically planned surfaces, controlled by elastic pressure which can be altered in an instant. all mechanical components (i.e., cone and wrist joints) and steel tubing have been left refinished (i.e., brushed metal finish sealed with a clear coat lacquer). the original brass shell socket with paddle switch by general electric socket has been rewired with period appropriate rayon cloth cord. the original hubbell brand "deep bowl" green porcelain enameled shade remains in great shape. the o. c. white company was incorporated in 1895, and began business at 65 beacon street in a very small way with only a few types of adjustable electric light fixtures, under patents originated by dr. otis c. white. during their peak in production the o.c. white company manufactured over one hundred different styles of lighting devices, including a large variety of portable lamps, desk fixtures, desk and table standards, wall brackets, floor portables and other types of fixtures in all finishes for use in business offices, banks, libraries and public buildings of every description, and also a great variety of heavy iron adjustable fixtures for use in machine shops, mills, factories. the company remained for ten years on beacon street and then having outgrown the old quarters, in 1905 removed to the heron street, where they remained for several years.
