Abstract

928,936. Chimney and ventilating shaft taps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 13, 1962 [May 15, 1961], No. 17606/61. Class 25. In a cowl for a chimney or ventilating shaft wherein the velocity of gaseous discharge entering the cowl is increased as it flows therethrough by a baffle defining a longitudina passage in alignment with the longitudinal axis of the chimney, the passage initially reduces in cross-section in the direction of flow and has a final parallel section, the cross-sectional area of which is adjustable, to cater for various quantities of gaseous matter being discharged from the chimney, by means of tubular removable inserts, which are available with differing outlet cross-sections. In the form shown, the cowl is secured to the chimney 1 by a flange 3 on an outer sheet metal casing 8 surrounding a baffle 7 which is of cross-section. An insert 9 is supported by means of an outwardly flanged portion 10 in a recessed portion 12 of the baffle 7. In a modification, instead of placing the inserts within the final section of cowl they are placed externally to extend upwardly from the top of the cowl. The velocity of gases leaving the cowl may be supplemented by fitting a fan in the chimney.
