Mechanical contrivance for creating a jet of air, consisting usually of a hinged box with flexible sides, which expands to draw in air through an inward opening valve and contracts to expel the air through a nozzle. Invented in medieval Europe, the bellows was commonly used to speed combustion, as in a blacksmith's or ironworker's forge, or to operate reed or pipe organs.
