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.

Technique

An example of a receptacle of the 1920s to 1930s. 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 & receptacles. 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 (Ref.. 3). The electrical industry was the first to take an interest in the large-scale use of bakelite since it met the enormous demand for insulating material. In the late 1920s, bakelite was used primarily as an insulating material. In the 1920s & 1930s, the electrical industry became a vast consumer of bakelite for plugs, sockets, switches, insulators & accessories (Ref. 4).
