LIBRARY CLOCK Thomas Mercer St. Albans No 1254 Ca. 1880 England
Signed: Thomas Mercer St. Albans No 1254
The eight-day, spring-driven fusee movement of this library clock consists of a going train with chronometer escapement on an engine-turned platform. The engine-turned backplate is signed and numbered by the maker in the following manner: MADE BY Thomas Mercer No 1254.
The matt-silvered dial has a Roman chapter ring with five-minute and minute divisions. The maker has signed and numbered the dial in the centre: Thomas Mercer St. Albans No 1254. Above the middle is a seconds ring with a finely cut blued-steel hand, whilst below the middle there is an up-and-down dial indicating the remaining duration of the movement (0-8). The time is indicated by a pair of blued-steel hands.
The rosewood case of the library clock has faceted glass windows on all sides so that the movement is clearly visible. The case is surmounted by a shaped brass carrying handle. Top and bottom of the case have mouldings and at the top a sculpted cornice, whilst the clock rests on four brass bun feet.
