Andrew Meikle
From Wikipedia, the free encyclopedia
Andrew Meikle (1719 – 27 November 1811) was an early mechanical engineer credited with inventing the threshing machine, a device used to remove the outer husks from grains of wheat. This was regarded as one of the key developments of the British Agricultural Revolution in the late 18th century. The invention was made around 1786, although some say he only improved on an earlier design.
Earlier (c.1772), he also invented windmill 'Spring sails', which replaced the simple canvas designs previously used with sails made from a series of shutters that could be operated by levers, allowing windmill sails to be quickly and safely controlled in the event of a storm.
Meikle worked as a millwright at Houston Mill in East Linton, East Lothian, and inspired John Rennie to become a noted civil engineer.
He died at Houston Mill and is buried in East Linton's Prestonkirk Parish Church kirkyard, close to Rennie's father, George Rennie, who farmed the nearby Phantassie estate by the River Tyne.
