Horse gin


A horse mill is a mill, sometimes used in conjunction with a watermill or windmill, that uses a horse as the power source. Any milling process can be powered in this way, but the most frequent use of animal power in horse mills was for grinding grain and pumping water. Other animal engines for powering mills are powered by dogs, donkeys, oxen or camels. Treadwheels are engines powered by humans.

In Antwerp, Belgium, the Brewers' House museum is a good example of horse-powered pumping machinery. The building dates from the 16th century; although the original wooden machinery was replaced in cast iron in the mid-19th century, the original layout has been retained.

This horse mill has not been used since about 1830 when it was superseded by portable engines. It was rescued from Berwick Hills Low Farm in Northumberland by the museum, repaired and set up in their own gin gang at Home Farm as a non-functioning exhibit. The top of the mill's main vertical axle and the end of the main drive shaft are pivoted at the centre of their own separate tie beam which is below and parallel with the main roof tie beam, and set in the gin gang's side walls at either end. The mill's tie beam has to be stabilised with two massive oak beams which run, either side of the drive shaft, from tie beam to threshing barn wall. A large and basic engine like this can create great stresses from the torque engendered.
