Year: 1864

page_text: LETTERS PATENT to William Henry Kelsey, of Rotherhithe, in the County
of Surrey, Builder, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF CHIMNEYS AND FLUES FOR HOUSES AND OTHER BUILDINGS."
Sealed the 13th April 1865, and dated the 14th October 1864.
PROVISIONAL SPECIFICATION left by the said William Henry. Kelsey
at the Office of the Commissioners of Patents, with his Petition, on the
14th October 1864.
I, WILLIAM HENRY KELSEY, of Rotherhithe, in the County of Surrey,
Builder, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF CHIMNEYS AND FLUES FOR HOUSES AND OTHER BUILDINGS,"
to be as follows:-
My Invention has for its object the saving of space and material in the
construction of houses and other buildings, and also the prevention of smoke
and consequent saving of fuel.
In the ordinary mode of constructing chimneys there is a separate flue for
each fire-place in the house or building formed in the chimney breast, but my
Invention consists in constructing the chimney breast with a single flue for
one series of fire-places throughout the several floors, thereby admitting of
the discharge of the smoke at a single outlet at the top of the chimney. For

page_text: this purpose a register for the fire-place on each floor is inserted in the brick-
work of the chimney, by means of which the communication between such
fire-place and the common flue is opened or closed as required; and this
register is adjusted to the degree of opening required by means of a rack or
other suitable-means. The top of the chimney piece is covered by a slab or
by other means, the jambs of the chimney-piece. forming the receiver for the
stove. There is also inserted in the brickwork at the bottom of the chimney
a soot door, contained in a box or frame, such door being secured in a groove
formed therein, which admits of its being removed when required in order to
give access to the interior of the flue for the purpose of clearing away the
soot.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Kelsey in the Great Seal Patent Office on
the 13th April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY KELSEY, of Rotherhithe, in the County of Surrey, Builder, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

said William Henry Kelsey, Her special license that I, the said -William
Henry Kelsey, my executors, administrators, and assigns, or such others as
I; the said William Henry Kelsey, 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 "IMPROVE-
MENTS IN THE CONSTRUCTION OF CHIMNEYS AND FLUES FOR HOUSES, AND OTHER
BUILDINGS," upon the condition (amongst others) that I; the said William
Henry Kelsey, by an instrument in writing under my hand and seal, should
particularly 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 imme-
diately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said William Henry. Kelsey, 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 fol-
lowing statement, reference being had to the Drawings hereunto annexed, and
to the letters and figures marked thereon (that is to say):
My Invention of " Improvements in the Construction of Chimneys and
Flues for Houses and other Buildings has for its object the saving of space
and material in the construction of houses and other buildings, and also the
prevention of smoke and consequent saving of fuel.
In the ordinary mode of constructing chimneys there is a separate flue for
the fire-place on each floor in the house or building formed in the chimney
breast, but my Invention consists in constructing the chimney breast with a
single flue for one series of fire-places throughout the several floors, thereby
admitting of the 'discharge of the smoke at a single outlet at the top of the
chimney. For this purpose' the chimney breast is constructed with a single
flue from top to bottom, and a register for the fire-place on each floor is
inserted in the brickwork of the chimney, by means of which the communi-
cation between such fire-place and the common flue is opened or closed as
required; and this register is adjusted to the degree of opening required by
means of a rack or other. suitable means. The top of the chimney piece is
covered by a slab or by other means, the jambs of the chimney piece forming
the receiver for the stove. There is also inserted in the brickwork at the
bottom of the chimney a soot door contained in a box or frame, such door
being secured in a groove formed therein at the top and bottom, which admits
of its being removed when required in order to give access to the interior of.
the flue for the purpose of clearing away the soot.
Having thus stated the nature of the said Invention, I will proceed to
describe more particularly in what manner the same is to be performed by
reference to the accompanying Drawings, in which are represented a portion
of a chimney and a register and soot door, all constructed according to the
Invention

page_text: floor; Figures 7 and 8 are similar views of the soot door at the bottom
of the flue. In these several Figures the same letters of reference: indicate
corresponding parts.
E is the chimney breast, the front of which; as will be seen on reference-to
-Fig. 3,-extends-but-a slight distance beyond the wall, and when a thicker wall
is used it may be flush with it; F is the flue; extending through all the floors
from top to bottom of the chimney; Gis the chimney piece, the jambs of
which form a receiver for the stove; H is a slab or cover for the chimney
piece, in which slab or cover is formed an aperture I for the escape of smoke
and heated vapor from the fire-place into the flue when the register is open,
as shewn in Fig. 2. This register consists of a flap or valve K which is
formed with a groove at the top and bottom so as to fit on to a rib fixed in the
cavity in the brickwork-of the chimney,-or-the-frame-made-to-receive-the
register, and to be capable of turning on such rib as on a pivot. The degree
of opening of the flap K is regulated by the rack L, which is suspended from
a pin m, as shewn in Fig. 6. In this Figure the flap K is shewn open to
the full, and it is indicated by dotted lines as closed, but it is obvious that it
can be fixed in an intermediate position by moving it on its pivot and allowing
the rack. L to fix it by holding the top of the flap in one of its notches. The
required: adjustment of the position of the flap may be effected by other
means. N is a frame inserted in the bottom of the flue F, in which is fitted.
a door O capable of being removed when required in order to afford access to
the flue for the purpose of clearing away the soot. This door is secured in
grooves at top and bottom, and may be readily removed by raising it, so as to
admit of its lower part being drawn out, the upper groove being-of-sufficient
depth for the purpose.
"
The above-described soot door may be adapted and applied to chimneys of
the ordinary construction.
%
Having thus described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that I do not claim as
my Invention any of the parts represented and described otherwise than as
herein-after stated; but what I do claim as of my Invention is,―
of
First, the construction of chimney breasts in houses and other buildings
with a single flue for one series of fire-places throughout the several floors, as
herein-before described., -

.. Secondly, the adaptation and application to the chimney or flue of a register
capable of being adjusted in the manner described by means of ,a rack, or by
other suitable means, for the purpose of putting the fire-place on each floor

page_text: into communication with the common flue as required, and also for regulating
the draft from the fire-place into the flue..
And, lastly, the adaptation and application of a moveable soot door to the
bottom of the chimney, as herein-before described.
In witness whereof, I, the said William Henry Kelsey, have hereunto
set my hand and seal, the Eleventh day of April, in the year of our
Lord One thousand eight hundred and sixty-five.
