The lower Setof Louvres are constructed so that they willgive a direction to the wind impinging againstthem, and cause an upward current. TheTop Louvres also tend to increase the upwarddmugbt, while at the same time they afforda ready outlet for the wind should it blowinto the Chimney Top; and if the wholeforce of the wind be not expended throughthe Top Louvres, then the rarified air in theInner Flue, which it should be observed iscarried above the Louvres, assisted by thedraught from them will effectually check itspassage into the Chimney. In this Chimney Top there can be nolodgment of Soot, the wind blo«ing constantlythrough it: there is no revolving machineryto get clogged with Soot and rendered useless,and it is the only efficient Zinc Chimney Topyet Invented which can he thoroughly sweptby the Machine without injury.
