| B Hick & Son - Crank Overhead Engine
Continuing his father's great leap, John Hick MP represented Bolton in Parliament from 1868 - 1880. At home (Mytton Hall) however, he retreated regularly to his full steam driven workshop where Mrs. Hick stoked the vertical boiler! This particular 10nhp engine was shown by the company at the Great Exhibition in 1851, alongside their diminutive Oscillating engine. Geoffrey King, a professional Engineer and member of the Newcomen Society, detailed this 1" to 1' replica in 1956 from the original Hick drawing set. The vertical layout made this engine particularly suitable for driving "manufactory" line shafting, with the cylinder, valve chest and feed pump installed in a pit below. Where more that 10nhp was required, gangs of engines could be coupled together and managed by a single boiler and "engineer". Complete with its 7" x 8½" plinth the model stands almost 14" tall propelling a Ø7½" flywheel. With a bore x stroke of ¾" x 1 7/8", the engine has a double acting slide valve, an eccentric driven feed pump and a Watts type governor, driven directly from the crank with bevel gears. An imposing runner, the 'Crank Overhead' shows a great deal of movement when underway. The Hick & Son Crank Overhead in Action
