IMPROVEMENTS IN STEAM ROILERS AND IN ARRANGEMENTS CONNECTED THEREWITH.
Year: 1871

page_text: LETTERS PATENT to John Jordan, of Liverpool, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN STEAM
ROILERS AND IN ARRANGEMENTS CONNECTED THEREWITH.
ROILERS AND IN ARRANGEMENTS CONNECTED THEREWITH.
Sealed the 23rd April 1872, and dated the 4th November 1871.
PROVISIONAL SPECIFICATION left by the said John Jordan at the
Office of the Commissioners of Patents, with his Petition, on the
4th November 1871.
I, JOHN JORDAN, of Liverpool, in the County of Lancaster, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN STEAM BOILERS AND IN ARRANGEMENTS CONNECTED THEREWITH," to be as
follows:-
In carrying into effect my improvements in steam boilers and in the
arrangements connected therewith, I take large metal tubes, say of about
from 12 to about 15 or 18 inches diameter and of such lengths as may
be convenient, say from about ten to about eighteen feet long, the size

page_text: and length depending on the size of boiler and on the horse power
wanted, and I place them side by side on a suitable frame or frames
with more or less slight inclination, from say about six to about twelve
inches in the length of the tubes. At a distance above the tubes of
say about twelve inches I place another row of tubes with the same
inclination and parallel to the bottom row. These two rows of tubes
are connected together with tubes, say of about six to about eight inches
diameter, one at a short distance from each end of the tube immediately
below it. Proceeding in the same manner I place a third row at a
similar distance from the second row, and connect the tubes of which it
is composed to those of the second row by pipes of similar size to those
connecting the second and first rows. In this way I build up any
number of rows of slightly inclined parallel large tubes, always pre-
ferring an odd number of rows.
The frames carrying the tubes are arranged so as to form the sides of
furnaces and to carry the fire-grates upon which the fire is carried, and
the spaces between the tubes form the flues up and along which the
products of combustion are transferred and the heat abstracted by the
corrugated surface of the large tubes from the gases on their way to the
chimney. The ends of the tubes are fitted with man-holes to give ready
access to the tubes, and each bottom or lower end of each bottom tube
is connected to a feed main by a suitable sized feed pipe. From the
upper end of each top tube a connection is made to a steam main by
which the steam generated is led off for use as desired.
The sides and divisions of the fire-places and flues are lined with fire
resisting material of suitable size and shape for such purposes.
I enclose the whole nest of connected tubes as described with a sheet-
iron casing, doubled to enclose a portion of air and stiffened by being

filed by the said John Jordan in the Great Seal Patent Office
on the 3rd May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JORDAN, of Liverpool, in the County of Lancaster, Engincer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of November, 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 Jordan, Her special licence
that I, the said John Jordan, my executors, administrators, and assigns,
or such others as I, the said John Jordan, 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 STEAM BOILERS AND IN
ARRANGEMENTS CONNECTED THEREWITH," upon the condition (amongst others)
that I, the said John Jordan, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, 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 immediately after the date of the said
Letters Patent.
· NOW KNOW YE, that I, the said John Jordan, 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 in writing, that is to say :-
-
In carrying into effect my improvements in steam boilers and in the
arrangements connected therewith, I take large metal tubes, say of about
from twelve to about fifteen or eighteen inches diameter and of such
lengths as may be convenient, say from about ten to about eighteen.fect
long, the size and length depending on the size of boiler and on the

page_text: horse power required, and I place them side by side on a suitable frame or
frames with more or less slight inclination, from say about six to about
twelve inches in the length of the tubes. At a distance above the tubes
of say about twelve inches I place another row of tubes with the same
inclination and parallel to the bottom row. These two rows of tubes
are connected together with tubes, say of about six to about eight inches
diameter, one tube being placed at a short distance from each end of
the tube joined by the short tubes. Proceeding in the same manner I
place a third row at a similar distance from the second row, and connect
the tubes of which it is composed to those of the second row by pipes of
similar size to those connecting the second and first rows.
In this way
I build up any number of rows of slightly inclined parallel large
tubes, always preferring an odd number of rows.
The frames carrying the tubes are arranged so as to form the sides of
furnaces and to carry the fire-grates upon which the fire is carried, and
the spaces between the tubes form the flues up and along which the
products of combustion are transferred and the heat abstracted by the
corrugated surface of the large tubes from the gases on their way to
the chimney. The ends of the tubes are fitted with man-holes to give
ready access to the tubes, and the bottom or lower end of each bottom
tube is connected to a feed main by a suitably sized feed pipe. From
the upper end of each top tube a connection is made to a steam main by
which the steam generated is led off for use as desired.
The sides and divisions of the fire-places and flues are lined with fire
resisting material of suitable size and shape for such purposes.
I enclose the whole nest of connected tubes as described with a sheet-
iron casing doubled so as to enclose a portion of air, and stiffened by
being attached to the divisions forming the separate flues and fire-places;
the boiler or boilers consisting of one or more of these nests of con-
nected tubes is then ready for use.
The connecting tubes between each pair of large tubes project a short
distance into the same. At the higher end they project upwards, and at
the lower end they project downwards so as to direct the circulation of
the water.
Having now described the nature and object of my said Invention
for "Improvements in Steam Boilers and in Arrangements connected
therewith," together with the manner in which the same is to be or

page_text: may be performed or carried into practical effect, I would remark in
conclusion that I claim as my Invention, the general construction and
arrangement of steam boilers substantially in the manner herein-
before described.
In witness whereof, I, the said John Jordan, have hereunto set
my hand and seal, this Thirtieth day of April, in the year of our
Lord One thousand eight hundred and seventy-two.
JOHN JORDAN. (L.s.)
