Year: 1854

page_text: LETTERS PATENT to William 'Weatherley and William Jordan, of
Chartham, near Canterbury, for the Invention of "IMPROVEMENTS IN STEAM
.. BOILERS."
PROVISIONAL SPECIFICATION left by the said, William Weatherley and.
William Jordan at the Office of the Commissioners of Patents, with their
Petition, on the 15th March 1854.
We, WILLIAM WEATHERLEY and WILLIAM JORDAN, of Chartham, near Can-
terbury, do hereby declare the nature of the. Invention for "IMPROVEMENTS
IN STEAM BOILERS" to be as follows:
This Invention has for its object improvements in applying tubes within a '
flue, which passes through à: steam boiler," in order to get more extensive
heating surfaces. For this purpose a steam boiler is constructed with a flue"
which passes through it, as is the case with Cornish and some other boilers.
Interior of this flue and over the fire-place or furnace (which as usual is con-
structed within the tubular flue) is arranged an arch of tubes, which at their"
front ends are connected with a water space which by a' tube is connected with
the main boiler. The back ends of the tubes..are connected with a water

page_text: space, moveable within the flue, and connected by a tube with the main boiler.
To the back of this second water space are affixed numerous tubes which at
their back ends are fixed to another water space, also moveable in the interior
of the flue, and so on according to the length of the boiler flue. The water
spaces are so arranged as to form partitions transversely across the upper part
of the boiler flue, leaving a space below for the passage away of the heat and
products of combustion to act on the next series of tubes and the main boiler,
and, lastly, to the chimney or shaft. The last water space is connected with
the feed pump; hence the water is fed first through the tubes most distant
from the fire, and then through the hotter and hotter tubes, and the water
ultimately passes into the main boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Weatherley and William Jordan in the Great Seal
Patent Office on the 15th September 1854...
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
WEATHERLEY and WILLIAM JORDAN, of Chartham, near Canterbury, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of March, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said William Weatherley and William Jordan, Her special licence that
we, the said William Weatherley and William Jordan, our executors, adminis-
trators, and assigns, or such others as we, the said William Weatherley and
William Jordan, our 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 STEAM
BOILERS," upon the condition (amongst others) that we, the said William
Weatherley and William Jordan, by an instrument in writing under our hands
and seals, or under the hand and seal of one of us, 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

page_text: Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said William Weatherley and William Jordan,
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 applying tubes within a
flue which passes through a steam boiler in order to get more extensive heating
surfaces. For this purpose a steam boiler is constructed with a flue which
passes through it, as is the case with Cornish and some other boilers. Interior
of this flue and over the fire-place or furnace (which as usual is constructed
within the tubular flue) is arranged an arch of tubes which at their front
ends are connected with a water space which by a tube is connected with the
main boiler. The back ends of the tubes are connected with a water space,
moveable within the flue, and connected by a tube with the main. To the
back of this second water space are affixed numerous tubes, which at their
back ends are fixed to another water space, also moveable in the interior of
the flue, and so on according to the length of the boiler flue. The water
spaces are so arranged as to form' partitions transversely across the upper
part of the boiler flue, leaving a space below for the passage away of the
heat and products of combustion to act on the next series of tubes and the
main boiler, and, lastly, to the chimney or shaft. The last water space is con-
nected with the feed pump; hence the water is fed first through the tubes.
most distant from the fire, and then through the hotter and hotter tubes, and
the water ultimately passes into the main boiler..
Having thus stated the nature of our said Invention, we will proceed. to
describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a longitudinal section of. a boiler having our improvements
applied thereto; Figures 2 and 3 shew an end view and transverse section of
the boiler. In each of these Figures the same letters of réference indicate
similar parts. A, A, is an ordinary construction of steam boiler having through
it a tubular flue B, within which are the furnace or fire C, and ash pit D.
The construction and arrangement of these parts constitute no part of our
Invention, and the boiler may be varied in form so long as it is made with a
tubular flúe suitable for receiving apparatus according to our Invention; E, E,
is a water space in connection with the upper part of the boiler by the branch

page_text: pipe F. Over the fire there are a series of tubes connected at their front ends
with the water space E, and at their back ends by the water space G, which
fits the upper part of the interior of the tubular flue of the boiler, but allows
of the products-from-the fire passing under it. This water.space.G is supported
at its under side by the grooved wheel resting on a bar.H, which, is fixed
longitudinally at the bottom of the tubular flue B... It will thus be seen that
the fire heats the water in the tubes F; and also the water which is in the
boiler, and the products from the 'fire' then pass over the bridge I, thence
under the water space and partition G. The products then pass into that part
of the tubular flue which is between the water space.G and the water space G,
which like the water space G forms a partition across the upper part of the
tubular flue B. The water spaces G, G!, are connected by a'system of tubes
J, J, for containing water. The arrangement we prefer is shewn by the
. cross section drawn on the longitudinal section, Figuré 1, but the arrangement
of these tubular water spaces may be varied; G2 is another water space form-
ing an end to the flue B; and the water spaces G', G², are connected by tubes
in like manner to that just described; hence the heated products from the fire
will pervade the spaces between the partitions G, G', G², and heat the water in
the boiler, and also the water in the partitions, and also in the tubes J, J, which
connect the transverse water spaces or partitions G, G', G. The products
from the fire then pass away under the water space G² to a chimney or flue;
K is the water supply pipe, which passes through the flue B, and is connected
to the water space G²; hence it will be seen that the water is supplied to the
back end of the apparatus where the heat is least, and then passes forward and
becomes highly heated in the tubes J and water spaces G', G, from the latter
of which the water passes partly through the tubes above the fire and to the
front water space E, and thence to the boiler, whilst the water also passes
partly through the branch pipe L*, which connects the lower part of the water
space G with the lower part of the boiler, as shown. By this arrangement it
will be seen that the water-heating apparatus in the flue B is only in con-
'nection with the boiler at one end. Thus the exhaustion or contraction of
the parts of this apparatus may take place freely and without prejudice to its
stability; the heating apparatus can also be readily disconnected and moved
out of the flue B for repairs. In this Drawing three water spaces G, G', G²,
are shown to be used, but in constructing longer or shorter boilers this may. be
varied, and the details of construction and connections shewn in the Drawing,
although we believe the same to be the best and most convenient for the
purpose, may be varied without departing from our Invention; and we wish it

page_text: to be understood that what we claim is the combined apparatus herein
described arranged in the tubular flue of a steam boiler for heating water as it
passes to the boiler.
In witness whereof, we, the said William Weatherley & William Jordan,
have hereunto set our hands and seals, this Nineteenth day of
August, in the year of our Lord One thousand eight hundred and
fifty-four.
