An oil lamp is a lamp used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although their use is less common in modern times.
Beginning with Frederick Albert Winsor's 1807 exhibition at the Pall Mall, [3] gas lights steadily overtook candles and oil lamps as the dominant form of street lighting. Early gaslights required lamplighters, but by the late 19th century, systems were developed which allowed the lights to operate automatically.
Gas lamps gradually started replacing oil street lamps in the United States, beginning in the first quarter of the 19th century. [3] The first street in the world to be illuminated by gaslight was Pall Mall in London, starting in 1807. [1] [5] The first US city to use gas street lights was Baltimore, starting in 1817. [4]
In the beginning kerosene lamps along with burners, as well as cookers for fluid (wood alcohol, paraffin), gaseous fuels (town gas, propane, and natural gas) were made in the Lampen-Fabrik Ehrich & Graetz OHG (E&G) factory. By 1897 the firm was controlled by Albert's sons Max and Adolf Graetz.
The Crusie lamp consists of two lamp pans, one above the other. Fuel drip from the upper lamp pan fell into the lower pan minimizing oil/grease mess below the lamp. In the evolution to the Betty lamp, replacing the upper lamp pan with a metal wick holder inside the lower pan reduces the amount of metal needed for the lamp.

A moderator lamp provides a pressurized supply of oil to the lamp wick by use of a spiral spring-loaded piston operating on a cylindrical oil reservoir. A regulating mechanism, the "moderator", compensates for the varying force of the spring as the piston descends. The moderator is a wire that runs through a tube in the center of the piston.
