A terrestrial clockwork globe dating from c.1906.
The lacquered paper globe is in excellent condition. There is no staining or discolouration, no scratches or scuffs; the colours are all bright still and it has aged beautifully. An oval label is signed RICHARD’S CHRONOSPHERE, PATENT 19460, CABLE. Later versions of the same globe clock have SMITH & SONS on this label, others are named THE EMPIRE CLOCK, referring to the coloured mapping of the colonies.
A polished and lacquered brass stand supports the globe. This stands on a velvet-covered ebonised wood base protected under a glass dome.
The eight-day timepiece clock movement has a lever escapement and is wound, set and adjusted from the base. Stamped on the bottom plate is Made in France and 264.
Around the equator, a silvered brass ring is engraved with Roman clock numerals, painted black on one hemisphere and red on the other. The globe rotates over 24 hours and the time is indicated by the brass pointer; Red indicates it is day, black for night. The pointer is currently positioned over London, but it can be adjusted to any time zone.
A small globe representing the Sun can be screwed up and down its arc by hand. From one solstice to the next, it moves 23.5° above or below the equator, giving the Sun’s seasonal position.
Black lines on the sphere show the distances of shipping routes in miles. Cables are marked by red lines. Some currents, such as the Gulf Stream and Antarctic Drift, are indicated by feint geographical contour lines. Six oceans are named.
Overall dimensions, including the dome:
Height of the Chronosphere: 30cms
Diameter of sphere: 15.5 cm
