Rare early rack-lever movement by the Patentee, circa 1796.
Fullplate movement with 3-wheel train, pierced cock table, the fusee with no maintaining power and the lever mounted in slides. Rack-lever (dead-beat) escapement with 30 tooth escape wheel (lacking), flat steel balance. Later replacement enamel dial. 45 mm diameter, 13 mm deep, not including centre arbor.
Peter Litherland, Mount Pleasant, Liverpool. PATENT No 1889, June 1792. A form of non-detached lever escapement that was successful not only for him and his partners but also gave rise to what soon became a burgeoning Liverpool watchmaking industry and its exports to America – see my drawing of the escapement. NB: Examples numbered under 1000, especially as early and as well finished as this, are rare - most surviving examples of this date being of the cheaper non-fusee type.
Lacking cap, escape wheel, lever and hands, and all rather dirty. Otherwise appears complete and is an important although incomplete document concerning the earliest work of this important Liverpool watchmaker. Not working.
