The style of table clock called a 'bracket clock' evolved from the lantern clock.
When lantern clocks were given wooden cases and mounted on a wooden bracket, this gave rise to the term 'bracket' clock.
Early bracket clocks were wall-mounted and weight-driven but later models are spring-driven and are therefore table clocks.
Bracket clocks are distinguished by having a handle on the top and they are taller and narrower than a mantel clock.
From about 1750, London makers concentrated on bracket clocks; most longcase clocks after this date were made elsewhere.
