Abstract
144,935. Green, T., and Oldham, B. A. Oct. 2, 1919. Chimney and ventilating-shaft tops. - A chimney or ventilating shaft top of the kind in which an updraught is caused by air passing through tubes extending from the sides of the pot through the interior towards the outlet end, comprises an ejector tube b of upwardly increasing section in which is an axially-disposed nozzle a connected by one or more tubes a<1> with one or more openings a<2> in the wall. The smoke &c. is drawn by the ejector action through ports formed between the tubes a<1> and the wall. An outer casing or sleeve e, having apertures e<1> at its lower end, may surround the tube b, the space between the tube b and sleeve e being of upwardly diminishing crosssection. Air passing through the apertures e<1> creates a further ejector action at the mouth of the tube b. Radial division members f may be arranged between the openings e<1>. Moisture may be collected by a channel formed by a flange g and passed out through drainage holes g<2>; ribs g<1> on the sides of the tubes a<1> deliver moisture collecting on these tubes to the channel.
