PROVISIONAL SPECIFICATION.
Improvements in Chimney Pots.
I, RICHARD Fox of 59 Asylum Road, Peckham, in the County of Surrey, Zinc
Worker, do hereby declare the nature of this invention to be as follows :-
The object of this invention is to construct chimney pots in such a manner that
when applied to chimneys, a down draught may be reduced, and what are commonly
called smokey chimneys may be prevented.
In order to carry out this invention, although it is possible to make the article of
clay or other material, I prefer to make it of metal, either of zinc or galvanized iron.
The body of the pot is made cylindrical, the lower portion being square or oblong in
plan and having a suitable flange all round at the bottom. Near the top of the body
and to the outside of it there are soldered two pieces of metal, one in form of a hollow
truncated cone and the other of a similar shape but inverted. The two pieces of
metal at the edge of their larger diameters are soldered together, and at their smaller
ones they are soldered to the body of the pot. In the lower of these two cones a
number of holes are formed for the entry of air. Within the cavity formed by the
foregoing cones there is another cone placed a little below the outer one, a space being
left for the passage of air at its top and sundry small spaces at the bottom. Above
the body of the pot there is yet, attached to it by suitable supports, another.cone so
placed as to admit of a current of air passing between it and the previously mentioned
cones, into the upper part of the pot. The whole is surmounted by a dwarf cylinder
in which are sundry holes protected by wind guards.
By this arrangement any wind is induced to enter the holes in the lower cone. It
then passes through the small spaces and issues as a cylindrical stream into the body
of the pot from the space left between the inner and outer cones. The sinoke is thus
caused to rise by the ascending current of air, this action being increased by the air
which enters between the upper and next lower cone, and then flows out with the
smoke from the top of the pot into the atmosphere. To reduce the chance of the
wind exerting a down draught, the upper part of the pot has a number of side
openings protected by wind guards, as stated before, so that any wind beating down-
wards may find an escape through these wind guarded holes, without prejudice to the
ascending smoke.

Improvements in Chimney Pots.
I, RICHARD Fox of 59 Asylum Road, Peckham in the county of Surrey,
Zinc Worker, 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 :-
In order to carry out this invention althrough it is possible to make the article of
clay, or other materal. I prefer to make it of metal either of zinc or galvanized iron.
The body of the pot is made cylindrical the lower portion being square or oblong in
plan and having a suitable flange all round the bottom as indicated by letter A on
Sheet 2 of according to my drawings and B to top of base. Near the top of the
body and to the outside of it there are soldered two pieces of metal, one in form of a
bollow truncated cone and the other of a similar shape but inverted. The two pieces
of metal at the edge of their larger diameters are soldered together and at their
.

page_text: smaller ones are soldered to the body of the pot as indicated by latter C on drawing.
In the lower of these two cones a number of holes are formed for the entry of air.
Within the cavity formed by the foregoing cones there is another cone placed a little
below the upper one as indicated by letter D on drawing a space being left for the
passage of air at its top and sundry small spaces at the bottom. Above the body
which is indiented by letter E on drawing, there is yet attached to it by suitable
supports as indicated by letters on drawing another cono so placed as to admit of
a current of air passing between it, as indiented by letter Fon drawing, and the
previously mentioned cones. The whole being surmounted by a dwarf cylinder as
indicated by letter H on drawing in which aro sundry holes protected by wind guards,
as indicated by letter I on drawing.
It
By this arrangment any wind is induced to enter the holos in the lower cone.
then passes through the small spaces and issues as a cylindrical stream into the body
of the pot from the space left between the inner and outer cones. The smoke is thus
onused to rise by the ascending current of air. This action being increased by
the air which enters between the upper and lower cone, and then flows out with the
smoke from the top of the pot into the atmosphere. To reduce the chance of the
wind excerting a down draught the upper part of the pot has a number of side
openings protected by wind guards as before stated, so that any wind beating down-
wards miny find an escape through the wind guarded holes without prejudice to the
ascending smoke.
Having now particularly decribed 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.
To create an upward current to counteract the downward draft in Chimneys were
