Interesting ‘IMPROV’D PATENT’ movement, originally with Massey escapement, circa 1820, from the Alan Treherne collection.
£95.00
Capped fullplate fusee movement of unusual proportions and decoration, the name-bar never engraved for its intended retailer, but carrying its manufacturer’s(?) serial number, both cap and cock stamped D, signifying its Coventry origins. The original Massey escapement now being an early conversion to single-roller, with passing-flat, keeping the original lever and pallets, and retaining its rare separately mounted brass banking-block. Steel balance, spiral balance-spring. Enamel dial signed PATENT, gold hand. 42 mm diameter, 14.5 mm deep, not including centre arbor.
Edward Massey, Newcastle, Coventry and Liverpool, escapement manufacturer and Patentee of the first extensively used detached lever escapements. First identified and catalogued by Alan Treherne, the various types being designated from 1 to 5. Types I and 5 are the earliest and least common, followed by type-2 and then type-3. Type-4 is a seconds beating-variant, usually fitted with a type-3 roller, and is very rare.
NB: Banking-blocks tend to be found with the earliest use of Massey’s new detached escapement, circa 1815, using the type-1 steel roller, but the ‘IMPROV’D PATENT’ engraving on the cock would suggest this movement dates from the period that jewelled rollers were being used. If so, it was was probably converted from a type-2 or type-5 roller.
Dial with edge crack and lacking minute hand, otherwise in fine original condition, noting the conversion. Nothing broken and tries to tick when would, but sold as needing at least a service and fresh oil to work properly.
