Improvements in Chimney Pots.
We, JOHN MORGAN, of Sunnybank, Surveyor, and DAVID JEREMIAH, of James
Street, Plasterer, both of Pontardawe, in the County of Glamorgan, do hereby
declare the nature of this invention to be as follows:
Our invention relates to improvements in chimney pots.
It is to be the size of the flue for a height of about nine inches above its base
and from that point it is to be enlarged and to again taper to the top round
or of any other section.
The whole of the latter portion is to take the form of a pear. Below the
enlarged portion one or more protected air inlets are to be arranged in it.
The object of our invention is to provide a chimney pot which will allow a
certain quantity of air to enter at the bottom; also to allow sufficient space for
the heated air to expand after its entry into the pot, thereby making it lighter
to ascend and to carry with it the smoke and to allow the said space for the
expansion of the heated air, in order to prevent a down draught; the expanded
air thus forming a tight plug, which cannot be forced down into the flue.
The enlarged portion shall take place all round the pot or on two sides only.
Dated this 11th day of April 1899.

We, JOHN MORGAN, of Sunnybank, Surveyor, and DAVID JEREMIAII, of James
Street, Plasterer, both of Pontardawe, in the County of Glamorgan, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
―:
Our invention relates to improvements in chimney pots.
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of the chimney pot.
Fig. 2, is a plan on line AB showing the underside of the hood with the
air inlet.
In carrying our invention into practice, we construct the chimney pot a or
cowl tapering outwards from the base b and then inwards at the top of expansion

page_text: chamber c. The air inlet d or inlets have a hood e or hoods with perforations
or clear spaces f underneath corresponding with similar perforations in wall of
chimney pot for a limited current of air to enter through.
A bonnet g is added to the above at the top and is supported on corbels h, to
prevent down draught. This arrangement is common to other chimney pots and
therefore we do not claim this as any part of our invention.
It is to be the size of the flue for a height of about nine inches above its base
and from that point it is to be enlarged and to again taper to the top round
or of any other section.
The whole of the latter portion is to take the form of a pear. Below the
enlarged portion one or more protected air inlets are to be arranged in it.
The object of our invention is to provide a chimney pot which will allow a
certain quantity of air to enter at the bottom; also to allow sufficient space for
the heated air to expand after its entry into the pot, thereby making it lighter
to ascend and to carry with it the smoke and to allow the said space for the
expansion of the heated air, in order to prevent a down draught; the expanded
air thus forming a tight plug, which cannot be forced down into the flue.
The enlarged portion shall take place all round the pot.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The chimney pot arranged and constructed in the manner as fully described in
the above specification and illustrated in the accompanying drawing.
