Rare early rack-lever movement by the Patentee, circa 1796.
Rare early rack-lever movement by the Patentee, circa 1796. Capped fullplate fusee movement with pierced cock table, three-wheel train, no maintaining power and the lever mounted in slides. Rack lever escapement with 30 tooth escape wheel, flat steel balance. 44.5 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.
Examples pre-1800 are rare and, as early and as well finished as this, are very rare; most surviving examples of this date being the cheaper non-fusee type.
Lacking case bolt and spring, dial, hands, balance-brake and escapement staff with its pinion, a fusee chain present, but lacking one hook. Otherwise complete and an important document concerning the earliest work of this important Liverpool watchmaker. Not working.
