George Manwaring
of Marsh Place, London
1812 George Manwaring erected a 'Statical Hydraulic Engine' for Messrs. Cook and Co., at their Alum Works, near Whitby. This was fully described and illustrated in a Paper in 1826 [1]. It was arranged as a beam engine, the cylinder being supplied with water at a head of 170 ft. The water supply incorporated an air cushion close to the engine to prevent damaging water hammer. The valve gear was cam-operated. The description and an illustration are also provided in Douglas Self's fascinating website [2]
