How do brass weights operate the clock?

Heavy metal cylinders hang from cords wound around internal drums inside the trunk. As gravity pulls the weights downward, the stored energy turns the gear train to drive the hands and pendulum. Owners must periodically wind the cords to draw the weights back to the top of the case. This mechanical setup eliminates the need for springs in traditional longcase designs.

Where should a longcase clock be placed?

These tall instruments require a stable, level floor and a secure fixing to a solid wall to prevent movement. Keeping the case plumb ensures the pendulum swings evenly and the escapement ticks regularly. Avoid positioning them in areas subject to dampness or extreme temperature fluctuations, which can affect the timber case and internal metal parts.

What maintenance do weight driven clocks need?

Regular winding keeps the movement operational, matching the duration capability of the specific gear train, such as eight day runs. Periodic professional cleaning and oiling ensure the brass wheels and pivots avoid excessive wear. Checking the suspension spring and keeping the case level helps maintain accurate timekeeping over the years.
