Period
circa 1920+
Canada
An example of an American made 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 Westinghouse socket of circa 1920. 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). Besides the Edison screw socket & receptacle, other methods of supporting lamps appeared: most common were the Thomson-Houston, the Westinghouse & the bayonet types (Ref. 4). The lock socket was developed around 1900 to 1909 to avoid the stealing of lamps in public places.
