IMPROVEMENTS IN CHIMNEY TOPS
Year: 1862

page_text: LETTERS PATENT to John Edward Carter, of No. 3, Brownlow Mews,
Gray's Inn Lane, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN CHIMNEY TOPS."
Sealed the 9th June 1868, and dated the 30th December 1862.
PROVISIONAL SPECIFICATION left by the said John Edward Carter
at the Office of the Commissioners of Patents, with his Petition, on
the 30th December 1862.
I, JOHN EDWARD CARTER, of No. 3, Brownlow Mews, Gray's Inn Lane, in
the County of Middlesex, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN CHIMNEY Tops," to be as follows:-
This Invention has for its object improvements in chimney tops. For these
purposes, in constructing a top for a chimney according to my Invention,
angular or tapering wind guards are used, which partly cover, in longitudinal
channels, corrugations or spaces formed by bending the metal of which the
shaft of a chimney top is formed, and such wind guards are fixed on ridges or
convex parts formed on either side of a channel or corrugation in place of
employing similar angular or tapering wind guards fixed on to or forming
part with solid ribs fixed to the exterior surface of the hollow shaft of a
chimney top, as has before been done by me. The ridges or parts of the shaft
which are convex outwards, on to which the angular or tapering wind guards
are fixed, may be hollow on the interior of the hollow shaft of the chimney top,
so that internally, as well as externally of the hollow shaft of a chimney top.

page_text: there will be longitudinal channels; this, however, is not essential, as the two
sides of each ridge may be pressed close together. The body or shaft of a
chimney top may be of other materials than metal and be formed with longi-
tudinal channels or corrugations and have wind guards applied thereto. The
wider end of each of the angular or tapering wind guards fixed externally on
the ridges or sides of the channels or corrugations is upwards, whilst the
narrower end thereof is downwards, as was heretofore the case when using
similar wind guards, so that the external longitudinal channels formed in the
hollow shaft of a chimney top are more and more nearly covered in by the
wind guards as they ascend more and more from the bottom upwards. At
the upper ends of the wind guards a hollow truncated cone is fixed, which
comes over the upper ends of the tapering wind guards and over the channels
between them, so that any wind which may enter and rise up in the hollow
external channels will be caused to converge into the centre of the cone above
the top of the hollow shaft of the chimney top. Above the upper and smaller.
end of this cone one or more other cones, open at top and bottom, may be
placed and be secured at a distance apart from each other and from the cone
above mentioned. Over these cones a cylinder, open at top and bottom, may
be applied as heretofore, or the upper part of a chimney top may be otherwise
constructed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Edward Carter in the Great Seal Patent Office on the
30th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN.
EDWARD CARTER, of No. 3, Brownlow Mews, Gray's Inn Lane, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent,, bearing date the Thirtieth day of December, in the year of our Lord
One thousand eight hundred and. sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,.,
the said John Edward Carter, Her special licence, that I, the said
John Edward Carter, my executors, administrators, and assigns, or such
others as I, the said John Edward Carter, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of

page_text: Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN CHIMNEY TOPS," upon the condition (amongst
others) that I, the said John Edward Carter, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Edward Carter, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention has for its object improvements in chimney tops. For these
purposes, in constructing. a. top for a chimney according to my Invention,
angular or tapering wind guards are used, which partly cover, in longitudinal
channels, corrugations or spaces formed by bending the metal of which the
shaft of a chimney top is formed, and such wind guards are fixed on ridges or
convex parts formed on either side of a channel or corrugation in place of
employing similar angular or tapering wind guards fixed on to or forming
part with solid ribs fixed to the exterior surface of the hollow shaft of a
chimney top, as has before been done by me. The ridges or parts of the shaft
which are convex outwards, on to which the angular or tapering wind guards
are fixed, may be hollow on the interior of the hollow shaft of the chimney
top, so that internally as well as externally of the hollow shaft of a chimney top.
there will be longitudinal channels; this, however, is not essential, as the two.
sides of each ridge may be pressed close together. The body or shaft of a chimney
top may be of other materials than metal, and be formed with longitudinal
channels or corrugations, and have wind guards applied thereto. The wider
end of each of the angular or tapering wind guards, fixed externally on the
ridges or sides of the channels or corrugations, is upwards, whilst the narrower
end thereof is downwards,, as was heretofore the case when using similar wind:
guards, so that the external longitudinal channels formed in the hollow shaft
of a chimney top are more and more nearly covered in by the wind guards as
they ascend more and more from the bottom upwards. At the upper ends of
the wind guards a hollow truncated cone is fixed, which comes over the upper
ends of the tapering wind guards and over the channels between them, so that
any wind which may enter and rise up in the hollow external channels will be
caused to converge into the centre of the cone above the top of the hollow
shaft of the chimney top. Above the upper and smaller end of this cone one

page_text: or more other cones, open at top and bottom, may be placed and be secured
at a distance apart from each other and from the cone above mentioned.
Over these cones a cylinder, open at top and bottom, may be applied as here-
tofore, or the upper part of a chimney top may be otherwise constructed.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an external view of a chimney pot or top constructed and
combined according to my Invention; Figures 2 and 3 are horizontal sections
taken respectively at the dotted lines (1), (1), and (2), (2), in Figure 1.
a, a, are angular or tapering wind guards, the larger ends of these wind
guards are upwards; b, b, are projecting corrugations formed in the shaft of
the chimney top leaving hollow outer channels c, c, between them. The
wind guards a, a, are fixed to the projecting corrugations band partially enclose
the spaces formed by the channels c, c. Over the upper ends of the wind
guards and over the upper end of the corrugated shaft is fixed the cone & in
such manner that its lower end descends below the upper ends of the wind
guards a, and the upper ends of the channels c, c. Over the upper end of
the cone d is fixed one or more other cones e, e, as is shown, and over the
upper end of the cone d and over the cones e is fixed a cylinder f, which is
open at both of its ends.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
combination herein described.
In witness whereof, I, the said John Edward Carter, have hereunto set
my hand and seal, this Twenty-seventh day of June, in the year of
'our Lord One thousand eight hundred and sixty-three.
