This clock, made about 1700 by John Drury, London, illustrates a transitional stage between the typical brass lantern clock of the seventeenth century and the ‘long-case’ clock of the eighteenth century.

[edit] How it works

It is fitted with the anchor escapement, introduced about 1670, which requires a much smaller arc of swing than its predecessor, the verge. A longer pendulum, giving better control of the timekeeping, can therefore by employed. The lantern clock was designed for mounting on a bracket projecting from a wall, but with the introduction of the anchor escapement and long pendulum it soon gave way to the ‘long-case’ clock in which pendulum and weights were enclosed in a long wooden case resting upon the floor. The clock exhibited has only one hand, although at this period minute-hands were becoming fairly common. It is fitted with a ‘rack’ type of striking mechanism, invented by the Rev. E. Barlow in 1676, in which the hour struck depends solely upon the position of the hour-hand.
