About 1786 Scottish mechanical engineer Andrew Meikleinvented the threshing machine to remove the outer husks from grains of wheat. His machine used fluted rollers to feed sheaves of corn to a rotating drum which beat the corn against a curved casing (the concave). The ears of corn and the chaff then fell through a grating while the straw continued horizontally out of the drum casing.
Before the development of the threshing machine threshing was a very laborious process, done by hand with flails. By the 18th century it occupied about one-quarter of agricultural labor, providing employment to a very large number of workers.
