Elaborate Striking Sequences
Early 20th century, a quarter-hour chime sequences were added to the longcase clocks. Every hour the full chime-sequences sound, followed immediately by the hour strike. Then every quarter of each hour the chime plays a sound. Almost modern mechanical clock offers this features that plays Whittington chimes or St. Michael’s chimes, selectable by a switch mounted on the right side of the dial, also it can be muted. By adding this component to the longcase clock, all modern longcase clock have 3 weights instead of just 2. The left weight provides power for the hour strike, the middle provides power for the clock’s pendulum and general timekeeping functions, while the right provides power for the quarter hour chime sequences.
