1, HENRY BARFOOT of 74 Princes Road Notting Hill in the County of Middlesex,
Slater do hereby declare the nature of this invention to be as follows:-
The object of these improvements is to prevent down draught in chimnies-These
improvements relate to the construction of chimney pots and consists of the formation
of such pots so that the smoke or air to be emitted through them is transmitted
obliquely in an upward direction between the body and neck of a vase shaped
chamber made of galvanized Iron, Tin, Zine or any other suitable material, such
vase shaped chamber being constructed with a bell shaped mouth and the lower part
or body of this chamber is semi spherical in order to throw upwards any downward
draught that may enter at the Bell shaped mouth.

page_text: I, HENRY BARFOOT of 74 Princes Road Notting Hill in the County of Middlesex,
Slater, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement and accompanying drawing :-
The object of these Improvements is to prevent down draught in Chimnies. These
Improvements relate to the construction of Chimney Pots and consists of the
formation of such parts so that the smoke or air to be emitted through them is
transmitted obliquely in an upward direction between the body and neck of a vase
shaped Chamber made of Galvanized Iron, Tin, Zinc or any other suitable material;
such vase shaped Chamber being constructed with a bell shaped mouth and the lower
part or body of this Chamber is semi-spherical in order to throw upwards any
downward draught that may enter at the Bell shaped mouth.
At the upper or fancy portion of the Chimney Pot or Cowl I form and provide
the same with fancy scroll or other suitable pattern and having a projecting ridge
beneath and around the same, to which four vertical tubes or passages are fixed at or
about the sides or corners of the same and leading downward into the curved or
globularly formed space provided within the body of my Improved Chimney Pot
or Cowl and to which the leading or upward portion of the flue is joined and
connected and forms part of. The object or purpose of these tubes and the curved
scrolls, vanes or other suitable ornamental surroundings employed is intended to lead
the wind from whichever quarter it may beat and deflect it inward and downward
from the enlarged mouth of the said tubes into the semi-hemispherical or curved
globular space provided, as before referred to, which causes and very materially assists
the upward draught from the main flue and the free and speedy emission of the
smoke.
The top portion of the upward flue is by the form given to my Chimney Pot or
Cowl, so arranged as to be brought well within the line of the opening of the
upper part of the Chimney Pot or Cowl, so that any tendency of the wind to bear
downward, will by the curved scrolls or ornamental portions formed around the top
part, be partly led off and cannot otherwise force or bear into the mouth portion
of the upward or connecting flue, but enter into and around the semi-hemispherical
or curved globular space or chamber and in whirling around assisted by the down
draught likewise from the four vertically inclined tubes, must in finding exit outward
and upwards tend to impinge and assist in the free egress or emission of the
smoke or gaseous accumulations from main flue or flues and uptake.
The upper or fancy portion of the Chimney should be wider across at the top than
at the neck to further assist in the uprise of the smoke.
For the purpose of cleansing the Chimney or flue by the ordinary method of
sweeping which can be easily effected by my plan as the curve given to the upward
flue and the neck of the Chimney Pot or Cowl, is of such a form as to freely permit
of the brush passing direct from the main flue and through the upper.

page_text: In the accompanying Drawing Figure 1, is a vertical sectional view of my
Improved form of Chimney Pot or Cowl in position. Figure 2, is an elevation of
sanie and Figure 3 a cross section taken on the line a-b, in which the several figures
correspond to like or corresponding parts. A, A is the body or case forming
the chimney pot. B, is the internal hemi-spherical or curved globular space
formed therein, and C, the upward flue which is well recessed at its upper or open
part C, in the elbow space provided in the body of the said Chimney Pot or Cowl.
D, D, are the vertical tubes or passages and by preference of larger area opening
outwards at their upper end Dr, D' where they are suitably secured, and the said
tubes or passages lead downwards into the curved or globularly formed space B,
provided and formed within the body of the chimney pot or cowl and at the upper
portion of same I form and shape a scroll or leaf or as leaves or in other curved
fanciful design, so as to curve over and around as shewn at E, to catch or divert the
wind, from whatever quarter it may blow into and down the tubes D, D from the
enlarged mouth D¹ of each into the semi-spherical or globularly formed space B, and
in whirling around therein and in its escape to the main exit assists and creates an
upward draught from the adjoining flue C, at and around its delivery mouth (4.
I make the upper portion of the Chimney much wider in proportion than at the
neck and the curved form or design given thereto of such a shape as to tend or lead
the wind at all angles off and away in manner desired and downward through the
tubes D, D.
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 manner of forming and constructing Chimney Pot sor Cowls, either of metal or
other suitable material so that the diverted down pressure, current or draught given
or created by means of the vertical surrounding tubes into a semi-spherical or globular
space or chamber and creating in its escape an immediate upward and continuous
draught from the upward flue or partition space which leads direct from and to the
main flue to the exit substantially in manner herein illustrated and described.
