Bracket clocks are spring driven, rather than weight driven, making them more portable. They are referred to as bracket clocks due to the wall-mounts or brackets they were intially placed on. This clock contains a verge escapement. Escapements are mechanisms that prevent the stored energy held in the wound spring, or hoisted weights, from escaping too quickly. Instead, the escapement allows the stored energy to be released gradually, thereby regulating the movement and helping to maintain accurate timekeeping.
This clock was created by George Graham, a renowned maker of clocks, watches and scientific instruments.
