Abstract

216,276. Machin, J. G. April 3, 1923. Chimney tops.-A chimney top comprises a cylindrical pot a embraced by a metal sleeve c which is curved inwardly at its upper end n and to which is secured, by brackets h, a frusto-conical hcod g. The dimensions are such that the cross - sectional area of the annular space j between the parts c, g, at its narrowest point m is greater than the area of the opening e in the top of the sleeve c. In a modification, the sleeve c is dispensed with and the pot a extended upwardly to form the curved part n, the hood g being supported on ribs integral with the pot a.
