Bracket, table and spring-driven clocks

Spring-driven clocks freed timekeeping from the hanging weight. The coiled mainspring, documented from the fifteenth century, made portable table clocks possible; to even out its declining force, makers used the fusee, a conical pulley connected to the barrel by a gut line or chain. Renaissance table clocks from Augsburg and Nuremberg — drum-shaped, square or tower-shaped in gilt brass — were luxury scientific objects, often with astronomical dials and alarms.

After the pendulum, English makers developed the bracket clock: a wooden case with a carrying handle, a short pendulum with a verge escapement, and often repeating work to sound the hours on demand at night. Later examples use the anchor escapement. In the nineteenth century, 'table clock' became a broad term for spring clocks of every nationality.
