Canada: An example of a socket of a type used in Canada. Part of a large & varied collection of over 7500 electrical items acquired & documented by Ontario Hydro in the 1960s. The collection was thought to be the largest & most comprehensive of its kind in Canada & was donated to the National Museum of Science & Technology in 1992.
Function: An electrical wiring device used to support & connect to electricity a lamp or other electrical device.
Technical: An example of a keyless short shell socket. 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. 2). 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. Besides the Edison screw socket & receptacle, other methods of supporting lamps appeared including the Thomson-Houston, the Westinghouse & the bayonet types (Ref. 3)
