Chimney sections and a revolving, ventilated latrine
A privy that turns on a counterweight like a nuns' wheel and vents through the roof
The sheet gathers building services. Two sections show a chimney flue, and a detail describes a latrine whose privy seat turns like a nuns' revolving wheel and returns to its first position by a counterweight, with the ceiling above pierced by holes so that it can ventilate. A further section shows a privy that vents through the roof. A winch is sketched separately at the foot.
