PROVISIONAL SPECIFICATION.
An Improved Cowl (or Chimney Pot) for Curing Smoky Chimneys.
WILLIAM BEVITT, Hazelhurst, Romford, Essex, Engineer, do hereby declare
the nature of this invention to be as follows:-
My invention is to prevent the down-draught in chimneys, or to cure what is
commonly known as "smoky-chimneys." I attain the desired object by fixing a
cowl constructed on the principle as shewn in drawings accompanying this
Specification and from which it will be seen, that which ever way the wind blows it
cannot strike direct down into the chimney. When the wind is baffling
downwards it strikes the cone-shaped top A and passes through the opening as
indicated by the arrow (a). Should there be a steady wind, or calm, the smoke
escapes as indicated by the arrow (b). My invention embraces cowls of various
shapes, having conical hoods of a corresponding form. The cones A. & B. are-by
preference supported by flat ribs, (c) thus leaving a clear passage inside for the
chimney-brush. The cowls can be made of zinc, iron, terra-cotta, or other
substances.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
A cowl having a conical top as hereinbefore described and illustrated in
accompanying drawings; also simplicity, cheapness of construction, and effective in
its object.
