Longcase clock

This large longcase clock was made in London around 1760 by James Cox, with later modifications by Thomas Weeks. Measuring 258 cm in height, 104 cm in width, and 84.5 cm in depth, it is constructed from mahogany, glass, brass, ormolu, and enamel. The mahogany case rests on a rectangular plinth base and is glazed on all four sides. The structure divides into two primary sections: an upper hood holding the dial and movement, and a lower glazed body housing the mechanism. Four projecting brass Corinthian columns frame the corners, adorned with gilded brass lion's head mounts and a gilded brass frieze along the lower case. Gilded brass female masks decorate the heads of the hood arches.

The clock features a white enamel dial with the movement positioned behind it, visible through the rear glass panel. It utilizes a dead-beat escapement and a bar-balance driven by a weight suspended on an endless loop of chain. The winding power is provided by an atmospheric barometer comprising suspended glass vessels that rise and fall via rocking levers as mercury shifts with atmospheric pressure, driving a wheel train. Curved brass straps holding the barometer bowl are engraved 'Weeks’s Rl. Museum' and 'London 1806'.
