John Joseph Merlin : the ingenious mechanick, London : Iveagh Bequest, Kenwood : Greater London Council, 1985.The clock’s movement does not need winding, as it is powered by a large barometer-like mechanism in the case.ĭesigned by John Cox and the engineer John Joseph Merlin, the clock’s display of a scientific system is typical of the late 18th century fascination with the spectacle of science. Exhibited from 1768-1774 in John Cox’s popular Mechanical Museum at Charing Cross, it was widely advertised as the only working example of ‘perpetual motion’. This clock was made as a scientific curiosity.The mechanism does not need winding because it works likes a barometer, moving mercury between two large glass jars and translating the movement to the dial via a series of wheels. A star exhibit in his ‘Mechanical Museum’, it was celebrated as the first clock powered by ‘perpetual motion’. This clock was the work of James Cox, a jeweller who exported automata to India and China. In the 18th century, with the widespread interest in science, furniture sometimes incorporated elaborate mechanisms.
