What is a longcase clock?

A longcase clock is a weight-driven pendulum timekeeper enclosed in a tall wooden case that stands directly on the floor. These pieces protect the delicate hanging weights and long pendulum swing. Cabinet makers constructed them in sections comprising a hood, trunk, and base, utilising timbers like mahogany and oak to house the dial and movement.

How do bracket clocks work?

Bracket clocks operate using spring-driven movements regulated by a balance wheel or a short pendulum rather than hanging weights. A fusee mechanism controls the tension release. Enclosed in compact wooden boxes with glass panels, these portable clocks sat on tables, shelves, or wall brackets in smaller rooms.

How do I wind an eight day clock?

An eight day clock requires winding every week using a specialised key inserted into winding holes on the dial face. This action lifts the internal weights or winds the mainsprings. Careful handling ensures the movement remains undamaged during the winding process, maintaining the tension required to drive the gear train.

What is a fusee clock?

A fusee clock utilises a conical grooved pulley that regulates the power transmitted from the mainspring to the gear train. As the spring unwinds, the leverage changes to maintain even force. This mechanical innovation prevents the timekeeper from running fast when fully wound or slow as tension decreases, improving accuracy.
