Learn about Argand Lamps
The Argand lamp was a lamp that burned whale oil, colza, olive oil or other vegetable oil lamp and produced a brighter light than candles. It was invented and patented in 1780 by Frenchman Aimé Argand (1750 – 1803. Aside from the improvement in brightness, the more complete combustion of the wick and oil required much less frequent trimming of the wick.
Because of the weight of the oil, the reservoir was mounted above the burner, and the wick was supplied with fuel by a gravity feed.
The wick also differed from what had been previously used. It was sleeve-shaped, and set-up so that air could pass both through the centre of the wick and also around the outside of the wick before being drawn into chimney. The cylindrical chimney steadied the flame and improved the flow of air.
The Argand lamp, together with the Carcel lamp was in general use until about 1850 when kerosene lamps were introduced.
The Carcel lamp was invented by the French watchmaker Bernard Guillaume Carcel (1750–1818) to overcome the disadvantages of the Argand lamp. He invented a clockwork mechanism that that drove a small pump in the tank that fed the Colza oil from a reservoir below the burner. more...
