Canada
An example of a socket with a shade holder of a type made and used in Canada. Part of a large and varied collection of over 7500 electrical items acquired and documented by Ontario Hydro in the 1960s. The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the National Museum of Science and Technology in 1992.
Function
An electrical wiring device used to support & connect to electricity a lamp or other electrical device, with a holder for a lamp shade & a rosette to connect it to the ceiling.
Technical
This type of raised shade holder became available in the 1880s, used with glassware adapted from gas light fixtures. They began to be replaced around 1910-1919 by a screw thread shade holder./ 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./ For ceiling drop cords, the rosette was simplified into one piece of porcelain and the fuse was omitted (Refs. 1-2).
