A bellows is a device for delivering pressurized Air in a controlled quantity to a controlled location. Basically, a bellows is a deformable container which has an outlet nozzle. When the volume of the bellows is decreased, the air escapes through the outlet. A bellows typically also has a separate inlet and valves or flaps for ensuring that air enters only through the inlet and exits only through the outlet. METALLURGY Several metallurgical processes, such as iron Smelting and Welding , require so much heat that they could only be developed after the invention of the bellows. The bellows are used to deliver additional air to the fuel, raising the rate of combustion and therefore the heat output. Various kinds of bellows are used in Metallurgy :
The Ancient Chinese engineer Du Shi once applied water-power ( Waterwheel ) to operate bellows of a Blast Furnace forging Cast Iron . The Ancient Greeks , Ancient Romans , and other civilizations used bellows in Bloomery furnaces producing Wrought Iron . In modern industry, reciprocating bellows are usually replaced with motorized blowers. its basically like a pump that pumps out air MUSICAL INSTRUMENTS In Musical Instrument s, the bellows is often employed as a substitute or regulator for air pressure provided by the human Lung s. The following instruments use bellows: Cuckoo Clock s also use bellows.
