ENGLISH LANTERN CLOCK
An English seventeenth century lantern clock, made of brass and iron, c. 1660. The clock consists of going work, striking work and alarm and is driven by lead weights. The front fret shows two engraved dolphins and floral and foliate motifs. The corners and the centre of the dial are richly engraved with tulips and a tudor rose.
The maker has signed the clock above the centre of the dial, under the chapter ring:
Robert Cosbey at ye Dyall
in Rood Lane London
The time is indicated by one iron hand on the brass chapter ring with Roman hour, half-hour and quarter hours divisions
The day-going movement has going work with verge escapement and balance wheel (reinstated). The striking work, which is controlled by a countwheel, indicates each hour fully on a bell. The alarm is set with an alarm disc, the alarm time being indicated by the tail of the hand and shown on the disc in Arabic numerals for each hour.
