PROVISIONAL SPECIFICATION.
Improvements in or connected with Chimney Pots and the like.
I, RICHARD BAXENDALE, of Moor Road, Upper Wortley, near Leeds in the
County of York, Brick Maker, do hereby declare the nature of this invention to
be as follows:-
The object of my invention is to so construct chimney pots that the upward
draught in the chimney is considerably improved, whilst at the same time the down
draught, which often occurs with chimney pots at present in use, especially in windy
weather, is effectually prevented.
According to my invention I employ an outer casing round the upper portion of
the chimney pot, a space being left between the latter and the casing. Below the
casing, grooves or recesses are formed in or on the chimney pot, having the surface
of the said grooves or recesses inclined upwards at an angle towards the space
between the chimney pot and casing. This space may be divided longitudinally
into any number of parts, for the purpose of keeping the air currents separate.
As the wind blows against the chimney. pot, it enters the grooves or recesses,
which divert it upwards into the space between the chimney pot and casing.
The uprising air surrounding the chimney pot has a drawing effect on the smoke
in the chimney, which is ejected without being mixed with the said air. In this
manner the chimney is caused to draw better in windy weather, and the disadvantage
of a down draught is entirely obviated.

COMPLETE SPECIFICATION.
Improvements in or connected with Chimney Pots and the like.
I, RICHARD BAXENDALE, of Moor Road, Upper Wortley near Leeds in the
County of York, Brick Maker, 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 :-
.
The object of my invention is to so construct chimney pots that the upward
draught in the chimney is considerably improved, whilst at the same time the down
draught which often occurs with chimney pots at present in use, especially in windy
weather, is effectually prevented.
In order that my invention may be clearly understood, I will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer to
like parts in all the figures.
Fig. 1 is a vertical longitudinal section. Fig. 2 is a sectional plan, and Fig. 3 is
an outside view, showing a chimney pot constructed in accordance with my invention.
Round the upper portion of the chimney pot AI employ an outer casing B,
which is placed at a suitable distance from the said chimney pot A so as to form a
space C between them. The top or upper portion A' of the chimney pot A is
preferably at or about the centre of the casing B, and such casing B is connected
to the said chimney pot A by means of the stay pieces or ribs D, which also serve
to divide the space C vertically for the purpose of keeping the air currents
separate

page_text: Below the casing B and on the chimney pot A I provide projecting ribs D₁
which preferably run down to the base and may be a continuation of the ribs D
as shown, thereby forming grooves or recesses E, which have their surfaces inclined
upwards towards the space C between the chimney pot and casing.
As the wind blows against the chimney pot, it enters the grooves or recesses E
formed by the ribs D', which divert it upwards into the space C between the
chimney pot A and casing B.
The uprising air surrounding the chimney pot A has a drawing effect on the
smoke in the chimney, which smoke is ejected without being mixed with the
said air.
By the employment of chimney pots as above described, it will be found that
the draught up the chimney is considerably improved, at the same time the down
draught, which so frequently occurs with chimney pots at present in use, is entirely
obviated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In chimney pots, the casing B at upper part thereof, in combination with stay
pieces or ribs D and projecting lower ribs D¹ substantially as and for the purposes
set forth.
2. The combination with a chimney pot A having an expanded outwardly curved
base parts; of lower projecting ribs D', and upper stay pieces D supporting an
outer casing B around the upper part of the chimney pot, upwardly curved grooves
or recesses E being thereby formed to direct the air currents upwards between the
pot A and casing B, substantially as herein shown and described with reference to
the accompanying drawings.
3. The general arrangement, construction and combination of the various parts
forming the improved chimney pot, substantially as herein set forth, together with
any mere modification or modifications thereof.
