Period
THIS TYPE OF SOCKET USED C. 1883- EARLY 1900S, AND POSSIBLY LATER.
Canada
PART OF A LARGE & VARIED COLLECTION OF ELECTRICAL ITEMS ACQUIRED & DOCUMENTED BYONTARIO HYDRO IN THE 1960S. THIS COLLECTION CONSISTS OF OVER 7500 ARTIFACTS, AND IS THOUGHT TO BE THE LARGEST & MOST COMPREHENSIVE IN CANADA. IT WAS DONATED IN ITS ENTIRETY TO THE NATIONAL MUSEUM OF SCIENCE & TECHNOLOGY IN 1992.
Function
TO SECURE AND CONNECT AN ELECTRICAL BULB WITHIN A FIXTURE.
Technical
EDISON'S IDEA FOR DESIGNING A SCREW SOCKET WAS PROMPTED BY SCREWING THE CAP ON A KEROSENE CAN. A SCREW FITTING ALLOWED THE BULB TO BE FIRMLY SEATED WITHOUT RISK OF DAMAGE TO THE DELICATE FILAMENTS, AND BY THE 1880S 70% OF SOCKETS SOLD WERE EDISON'S. SWITCHED LAMP HOLDERS WERE AN IDEA LEFT OVER FROM THE DAYS OF GAS LIGHTING, AND IT TOOK PEOPLE A WHILE TO GET USED TO THE CONVENIENCE OF SWITCHING A LIGHT ON/OFF NEAR THE ENTRANCE TO A ROOM. THE DEMAND FOR SWITCH SOCKETS CONTINUED IN SPITE OF FREQUENT EFFORTS BY ENGINEERS & INSURANCE INTERESTS TO DISCOURAGE IT. (REF. 1)
