turn-cap

Another cause is strong winds. The remedy is a turn-cap on top of the chimney. Another cause is the roughness of the inside of a chimney, or projections which impede the passage of the smoke. Every chimney should be built of equal dimensions from bottom to top, with no projections into it, with as few bends as possible, and with the surface of the inside as smooth as possible.

The only remedy for this inconvenience is, to raise the funnel higher than the roof, supporting it, if necessary, by iron bars; for a turn-cap in this case has no effect, the dammed up air pressing down through it in whatever position the wind may have placed its opening. Chimnies otherwise drawing well are sometimes made to smoke by the improper and inconvenient situation of a door.
