The years between to witnessed a rapid growth in the use of electric light and with it significant improvements in the design of light sockets. An understanding of what these changes were and when they occurred provides a valuable tool for dating early electric lamps. This discussion will gloss over internal modifications and focus on the external appearance, as this aspect is the most useful for on-the-spot assessments.
Although Edison invented the first functional electric light bulb in , more than 20 years would pass before his revolutionary device was practical enough to be embraced by the mass consuming public. In fact, early electrical systems were exorbitantly expensive to install and to maintain, as well as subject to frustrating service interruptions and frightening power surges. During this formative period, Edison’s DC direct current system dominated the market and his “Bergmann” socket was the prototypical design.
The first real challenge to Edison’s hegemony came with the inauguration of Westinghouse’s AC alternating current system in The Thompson-Houston Co. This shell design was the standard until , when Philip Lange patented an improvement that did away with the expensive solid brass cap of the earlier model. Lange’s patent utilized a sheet metal cap with a small strap across the inside to anchor the 2 screws that held the socket shell together and the internal body in place.
It was soon adopted by most suppliers and would remain a ubiquitous feature of mainstream socket architecture for the next 20 years. The Lange socket of the s was basically cylindrical in shape with an angular cap whose lower edge covered the top of the socket tube. Switched models were equipped with a flat paddle that might or might not have the company’s logo impressed in it.
Because the electric market was still small, not a lot of these Lange sockets were made and they are somewhat of a rarity today.

Plugs and sockets for portable appliances started becoming available in the s. A proliferation of types developed to address the issues of convenience and protection from electric shock. Today there are approximately 20 types in common use around the world see AC power plugs and sockets , and many obsolete socket types are still found in older buildings. When electricity was first introduced into houses in the s, it was primarily used for lighting. One common approach for other appliances such as vacuum cleaners, electric fans, smoothing irons and curling tong heaters was to connect to light bulb sockets using lampholder plugs.
As electricity became a common method of operating labour-saving appliances, a safe means of connection to the electric system other than using a light socket was needed.

Plug sockets do not produce energy if they are not switched on, and empty sockets do not produce electricity because you need a full-completed circuit to get the energy flow. At the first sign of a breeze, most people blast the heating on to warm up the house quickly. The fix to this is keeping the thermostat at a lower temperature for longer, progressively warming up your home without having to produce all of this heat straight away.
One of the other big offenders when it comes to heating is showers. But showering tends to rack up a large sum of the heating bills. You can remedy this by turning on the water at the last minute. Another option could be leaving the water running if multiple people need showers in the morning. You should also turn the shower pressure down as this uses up a lot more water, sometimes even more than a bath would.
But there are means and ways to reducing the amount of energy used in the process. Firstly, you should try washing your clothes at a lower heat where possible. Setting your machine at a lower temperature will reduce the amount of energy used and save you money on your bills. You should also consider what you are washing, for example items like towels need to be washed at a high temperature to kill any germs or bacteria.

Only buy and use 3-pin plugs which comply with the safety requirements. Do not buy or use any adaptor or extension unit which is fitted with irregular socket holes. Each socket must only allow one type of plug to be inserted. To prevent circuit overload and fire, no more than one adaptor or one extension unit should be inserted into a socket outlet. No adaptor should be inserted into any extension unit or vice versa. Stop using an adaptor or extension unit if its socket holes cannot firmly hold a plug or if it is too hard to insert a plug into it.
