The Franklin stove is a metal-lined fireplace named after Benjamin Franklin, who invented it in 1741. It had a hollow baffle near the rear (to transfer more heat from the fire to a room's air) and relied on an inverted siphon to draw the fire's hot fumes around the baffle.
The iron stove would be located on the hearth, projecting out into the room so that the heat radiated from the stove.[1] Other stoves at the time would not use heat radiation as a way to warm up the air. To deal with the loss of heat seen in other stoves Franklin created several devices within his stove. The first was called an air box. This air box was to be used to draw fresh air into the stove to stoke the fire.[2] The second device for the Franklin Stove was known as the Air Siphon.
