PROVISIONAL SPECIFICATION.
A New or Improved Cowl.
I, THOMAS SCOTT WINTER, of Westoe Road, South Shields, in the County of
Durham, Surveyor and Valuer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a smoke-preventing cowl so constructed as to catch the
wind at almost any angle other than a direct downward current, though even in
such a case, the wind blowing into the contracted or conical space counteracts that
entering the top of the funnel.
According to this invention I form the upper end of a tubular chimney pot with
a conical cover held at a suitable distance above the end of the said pot by three
or more supports and having a large central opening of but little less diameter than
that of the pot itself. Supported a little above this conical cover is a second cover
of like shape except that its outer and lower edge is turned upwards and surmounted
by a semi-circular ridge. In section this cover is of V shape having perforations
at its lower part to allow of the escape of rain which would otherwise collect in the
annular channel which it forms. Inside this second cover is supported a slightly
conical tube open at both ends and forming a continuation of the chimney pot
proper. This tube being open at its upper end presents a clear passage for the
Sweep's broom.

COMPLETE SPECIFICATION.
A New or Improved Cowl.
I, THOMAS SCOTT WINTER, of Westoe Road, South Shields, in the County of
Durham, Surveyor and Valuer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to a smoke-preventing cowl so constructed as to catch the
wind at almost any angle other than a direct downward current, though even in
such a case, the wind blowing into the contracted or conical space counteracts that
entering the top of the funnel.
According to this invention I form the upper end of a tubular chimney pot with
a conical cover held at a suitable distance above the end of the said pot by three
or more supports and having a large central opening of but little less diameter
than that of the pot itself. Supported a little above this conical cover is a second
cover of like shape except that its outer and lower edge is turned upwards and
surmounted by a semi-circular ridge. In section this cover is of V shape having
perforations at its lower part to allow of the escape of rain which would otherwise
collect in the annular channel which it forms. Inside this second cover is supported
a slightly conical tube open at both ends and forming a continuation of the chimney
pot proper. This tube being open at its upper end presents a clear passage for the
sweep's broom.
And in order that my invention may be more fully understood and carried into

page_text: practice I will now proceed to describe the same with reference to the accom-
panying sheet of drawings, of which
Fig. 1 is a part section and part elevation of a cowl constructed according to my
invention, and Fig. 2 is a similar view of a modified form of the same.
As shown at Fig. 1 the upper end of a tubular chimney pot a is provided with
a conical cover b held at a suitable distance above the end of the said pot by
means of three or more supports e and having a large central opening of but little
less diameter than that of the pot itself. Supported by stays d above the conical
cover b is a second cover e of like shape excepting that its outer and lower edge is
turned upwards and surrounded by a semi-circular ridge f. This cover is per-
forated at g along its lower edge so as to allow of the escape of rain which would
otherwise collect in the annular chamber which it forms. Inside this second
cover e is supported by means of stays ha slightly conical tube ; open at both ends
and forming a continuation of the chimney pot a.
In a modified arrangement shown at Fig. 2 the parts are arranged in substantially
the same manner as that already described, the principal modification being the
formation of the conical cover in one with the top of the chimney a, so that there
is no air space between these parts as there is in the arrangement shown at Fig. 1.
Those parts corresponding in both the drawings are marked with the same
reference letters. The arrows indicate the direction of the wind entering the cowl
at its sides.
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 :-
The improved construction of cowls substantially as and for the purpose herein-
before set forth and described and illustrated in the accompanying drawings.
