Year: 1871

page_text: LETTERS PATENT to John Huish Wehber, of King's Road, Chelsea,
in the County of Middlesex, Engineer, for the Invention of "Im-
PROVEMENTS IN CHIMNEY FLUES, AND IN APPARATUS CONNECTED THEREWITH
FOR WARMING AND VENTILATING,"
Scaled the 23rd January 1872, and dated the 28th August 1871.
PROVISIONAL SPECIFICATION left by the said John Huish Webber
at the Office of the Commissioners of Patents, with his Petition,
on the 28th August 1871.
"
I, JOHN HUISH WEBBER, of King's Road, Chelsea, in the County
of Middlesex, Engineer, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN CHIRNEY FLUES, AND IN APPARATUS CONNECTED
THEREWITH FOR WARKING AND VENTILATING," to be as follows:-
The object of my said Invention is to prevent chimneys from smoking
and to warm and ventilate apartments.
The nature and description of my said Invention consists in making
and fixing a tube inside the top or other part of a flue of less dimensions
than the said flue, so as to leave a vacancy all round the tube, and then
by enclosing the top and bottom of the vacancy form a receptacle or

page_text: chamber for air to be warmed by the smoke and heated air passing
through the tube from a fire lighted in the chimney below.
When the apparatus is used at the top of a flue I would make it of a
tubular form of less size than the flue itself with an inverted hopper at
the bottom adapted to the form of the flue and tube to fit close against
the sides of the flue or built into the brickwork by means of a flange
projecting round the bottom of the inverted hopper, and at the top I
would have a flange or plate with a collar formed and fixed round the
tube and made to lay on the top of the flue and thereby suspend the
apparatus and prevent its slipping down the chimney; and in some cases
I would form the tube with flanges at top and bottom and build them
into the flue, and thereby form a chamber between the tube and sides of
the flue for the heated air.
The apparatus would be either dropped into the flue from the top, as.
in the case of old chimneys, or would be built into the flue when the
chimney is new, showing a portion of the tube outside above the top of
the flue.
When an ornamental or other chimney pot is required I would some-
times keep the top of the tube on a level with the top of the chimney
pot, but in some cases I would only pass it up a short distance and then.
cover it with the chimney pot, or I would sometimes make the upper
part of the tube of an ornamental character to serve as a chimney pot-
itself, or I would sometimes finish the upper part of the tube with a roll
or flange, and sometimes with one or more conical rims with apertures
in the tube immediately under the same to admit external air into the
upper part of the tube. In this latter case the tube would stand up to
any required height, and a plinth or flange would be formed round the
same to carry the tube when fixed or dropped into the flue.
When the apparatus is applied to the lower or other part of a flue I
would make it with a tube smaller than the flue, with hoppers or flanges
top and bottom, the lower hopper being inverted and both hoppers made
to fit tightly against the sides of the flue or with flanges built in, thereby'
forming an air chamber similar to that before described.
When an apartment is required to be warmed by the said apparatus
I would make one or more apertures; in the side of the flue next the
apartment to communicate with the air chamber round the tube and:
thereby create a circulation that would drive the warm air into the
apartment; and when the flue is an outside one or where otherwise.

page_text: practicable I would introduce an open grating or valve for admission of
fresh air from the outside into the chamber and thence to the inside of
the apartment by means of the said apertures. For filling the apertures
herein described I would use any of the ordinary chimney gratings or
valves that would be suitable for the purpose, but the kind of valve I
prefer would be formed with a flap hung on pivots or otherwise balanced
to act as a throttle valve either with self-action or otherwise as would be
required. In some cases I would use inlet and outlet pipes to convey.
warm or fresh air to or from the air chamber to any part required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Huish Webber in the Great Seal Patent
Office on the 19th February 1872.
•
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HUISH WEBBER, of King's Road, Chelsea, in the County of Middlesex,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of August, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Huish Webber, Her special licence
that I, the said John Huish Webber, my executors, administrators,
and assigns, or such others as I, the said John Huish Webber, 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 Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
CHIMNEY FLUES, AND IN APPARATUS CONNECTED THEREWITH FOR WARMING AND
VENTILATINO," upon the condition (amongst others) that I, the said John
Huish Webber, my executors or administrators, by an instrument in
writing under or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, 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.
.

page_text: NOW KNOW YE, that I, the said John Huish Webber, do hereby
declare the nature of my said 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 prevent chimneys from smoking, and 5
to warm and ventilate apartments.
The nature and description of my said Invention consists in making
and fixing a tube inside the top or other part of a flue of less dimensions
than the said flue so as to leave a vacancy all round the tube, and then
by enclosing the top and bottom of the vacancy form a recepticle or 1
chamber for air to be warmed by the smoke and heated air passing
through the tube from a fire lighted in the chimney below.
When the apparatus is used at the top of a flue I make it of a tubular
form of less size than the flue itself, the bottom being made rectangular
or otherwise adapted to the form of the flue, leaving a space all round 1
the same for the admission of heated air; and for the more easy method.
of suspending the apparatus in the flue and at the top I would have a .
flange or plate with a rim or collar formed and fixed round the tube and
made to lay on the top of the flue and cemented to the brickwork,
thereby suspending the apparatus and preventing its slipping down the 2
chimney.
When an ornamental or other chimney pot is required I would keep
the top of the tube on a level with the top of the chimney pot and then
put the chimney pot over it, or I would sometimes make the upper part
of the tube of an ornamental character, to serve as a chimney pot itself, 2
or I would sometimes finish the upper part of the tube with a roll or,
flange, or sometimes with one or more conical rims with apertures; in
the tube immediately under the same to admit external air into the
upper part of the tube for creating a better draught. In this latter case,.
the tube would stand up to any required height, and a plinth or flange 3
would be formed round the same to carry the tube when dropped into:
the flue.
:
When the apparatus is applied to the lower part of a flue I would
'make it with a tube smaller than the flue itself, with a rectangular or
other shaped hopper adapted to the form of the flue both at the top and 8
bottom, with flanges to same to fit close or be built into the sides of the
flue, forming an air chamber all round the tube for the purpose. of
warming and ventilating an apartment. I would then form an aperture

page_text: in the side of the flue for the admission of cold air into the chamber, and
another aperture for the emission of warm air into the apartment, thereby
creating a circulation of air to warm or ventilate the apartment. Into
these apertures I would insert gratings or valves adapted for the purpose
and similar to those ordinarily used for chimney ventilation. Where
practicable I would introduce the cold air from outside by apertures and
ventilators before described, or I would sometimes convey the air by
tubes carried through the walls or floors from the outside to the air
chamber round the tube.
-
In order that my Invention may be fully understood I have hereunto
annexed a Sheet of Drawings, with figures and letters of reference marked
thereon, corresponding with figures and letters of reference in this
Specification. The same letters apply to the same parts in the several
