Abstract

150,145. Rogers, R. J. July 8, 1919. Chimney tops.-In cowls of the kind comprising a dome or cap h and a deflector c mounted over the uptake a, the deflector is spaced at a short distance from the shaft orifice so as to form a series of lateral slots or openings d. Air passing these slots after entering through holes l in the cap and impinging on the deflector induces a draught, whilst upward currents pass the slots and leave the cowl through the openings l in the cap. The top of the shaft is outwardly flared at g.
