An example of an "electrolier" type socket of the early 1890s. The first lighting fittings were often converted gas brackets or "gasoliers" & the latter soon developed into "electroliers", frequently of ornate design. Some of the early electroliers incorporated complicated devices to permit turning, swinging & adjustment of height. The simplicity of electricity soon gave rise to the plain pendant. A simple arrangement which did not require the service of a mechanic to change a lamp was a necessity for commercial production of electric lamp sockets. In 1880 Edison introduced the screw cap which still bears his name (Ref. 3). Edison had the idea for a light socket while screwing the cap on a kerosene can. It has the advantage of firmly seating the bulb without having to snap, pull or otherwise jar the lamp and its delicate filament. There were rival lamps before 1900, each with its own base, but Edison's base had 70% of the market in the early 1900s (Ref. 4). - Area Notes
