Synchronous clock cases

Abstract

Clocks for domestic use have been produced for four centuries. Historically, clock case design styles have been based on furniture design styles with the obvious constraints that the case must be big enough to enclose the movement, the dial must be legible, it must be possible to set the hands, and only available materials, usually wood, could be used. Cases were usually not much bigger than needed to enclose the movement. Addition requirements for synchronous movements are: provision for the mains lead and, for non self starting movements, access to a starting knob or lever. An adjacent socket (AC outlet) is needed. If this is behind the clock then the mains lead can be concealed. Contemporary advertisements always illustrated domestic synchronous clocks without any visible wiring. A wide range of materials was used for synchronous clock cases. In the 1930s materials no longer limited, but assisted case designers. Materials used included solid wood, plywood, brass, pewter, glass, porcelain, stone, and Bakelite. Later, aluminium and Perspex were also used. Domestic synchronous clock cases were of four main types: mantel clocks, bedside clocks, wall clocks, and granddaughter clocks. Some of the artistic styles used for domestic synchronous clock cases are illustrated.
