Bridge Lantern Maintenance Diagram
The drawing is water-stained but readable. Three ink lines connect the lamp house, the market drain, and a round chamber marked lower lantern - do not open during flood tide.
- Lamp house - shares the same flame path as the lantern well below.
- Valve chamber - marked with a brass key symbol.
- Side drain - safe bypass if the pressure wheel is turned first.
