AN IMPROVEMENT OR IMPROVEMENTS IN STEAM BOILERS
Year: 1853

page_text: LETTERS PATENT to Joshua Horton, junior, of Brierley Hill, in the
County of Stafford, Engineer and Boiler Manufacturer, for the
Invention of "AN IMPROVEMENT OR IMPROVEMENTS IN STEAM
BOILERS."
Sealed the 30th November 1858, and dated the 24th June 1853.
PROVISIONAL SPECIFICATION left by the said Joshua Horton at
the Office of the Commissioners of Patents, with his Petition, on
the 24th June 1853.
I, JOSHUA HORTON, junior, of Brierley Hill, in the County of Staf
ford, Engineer and Boiler Manufacturer, do hereby declare the nature
of the said Invention for "AN IMPROVEMENT OR IMPROVEMENTS IN STEAM
BOILERS to be as follows:
My Invention consists in so constructing a steam boiler that it may
be used as a puddling furnace boiler (that is to say, may be heated by
the waste heat of a puddling furnace), or as a firing boiler (that is to
say may be heated by an independent fire-place or fire-places). I

page_text: carry my Invention into effect as follows: I construct an ordinary
boiler furnace in the front part of the boiler, and I place a smaller fur-
nace on each side thereof, the said smaller furnaces being at right
angles to the larger one, and opening into it; these furnaces have one
common bridge, over which is a tube to deliver air and prevent the
formation of smoke; behind the bridge is the flue which conveys the
hot air from the puddling furnace; when the puddling furnace is at
work the three furnaces are not used, and it is necessary to close the
same in such a manner as to exclude the air which would enter and
injure the draught. The heated air is made to circulate around and
through the boiler in a way the details of which I do not consider it
necessary to describe.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joshua Horton in the Great Seal Patent Office,
on the 21st December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOSHUA HORTON, junior, of Brierly Hill, in the County of Stafford,
Engineer and Boiler Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of June, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Joshua Horton, Her special
licence that I, the said Joshua Horton, my executors, administrators,
and assigns, or such others as I, the said Joshua Horton, my execu-
tors, 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 "AN IMPROVE-

page_text: MENT OR IMPROVEMENTS IN STEAM BOILERS," upon the condition (amongst
others) that I, the said Joshua Horton, 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 immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joshua Iorton, 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):
My Invention consists, firstly, in constructing steam boilers so that
they may be used as puddling furnace boilers (that is to say, may be
heated by the waste heat of a puddling furnace), or as firing boilers
(that is to say, may be heated by an independent fire-place or fire-
places).
Secondly, in the method of circulating the heated air from the fur-
nace or furnaces through and around steam boilers.
Figure 1, represents in front elevation, Figure 2, in longitudinal
vertical section, and Figure 3, in longitudinal horizontal section, a
steam boiler constructed according to my Invention; Figure 4, repre-
sents a transverse vertical section of the same, taken through the line
a, in Figure 2; and Figure 5, represents a transverse vertical section
of the same, taken through the line 6, in Figure 2. c, is an ordinary
boiler furnace or fire-place in front of the boiler d; e, f, are two other
furnaces or fire-places, one on each side of the said furnace or fire-
place c, and opening into the same. The side furnaces e, f, are situated
at right angles to the furnace c, as represented. g, is the furnace
bridge, the said bridge being common to the three furnaces c, e, f; a
tube h, communicating at one end ', with the atmosphere, and at the
other end ", with the interior of the furnace, delivers air into the said
furnace immediately above the bridge y, and thereby prevents or
diminishes the production of smoke. The said tube h, is terminated
at the end ', with a register i, by which the amount of air introduced
into the furnace may be regulated. k, l, are tubes or passages situated

page_text: behind the bridge g, by means of which said tubes the heated air from
a puddling furnace or puddling furnaces may be introduced.
The course of the heated air and products of combustion is indicated
by the arrows in Figure 3, that is to say, the said heated air passes, as
indicated by the arrow m, on one side of the boiler, and crosses the
central hollow portion of the said boiler by means of the transverse
tubes n, n; it next pursues the course indicated by the arrows o, ]',
and arriving at the anterior portion of the boiler passes under and
across the same by the passage q; it eventually passes to the posterior
end of the boiler by the fluer, and from thence to the stack or chimney,
as indicated by the arrow s.
When the waste heat from puddling furnaces entering by the open-
ings, 1, is sufficient to produce the requisite quantity of steam, the
three furnaces c, e, f, are not used, and the said furnaces are closed as
effectually as possible in order to prevent the introduction of air.
When it is necessary to use the furnaces e, e, f, instead of the heated
air delivered from a puddling furnace by the pipes k, l, I prefer to
charge the said furnaces alternately, so that the fuel in two of the said
furnaces shall be in an advanced state of combustion when another is
being charged; in this way a very uniform heat and generation of steam
is secured, and suppression of smoke effected. When I construct a
double boiler I use only two fire-places to each boiler. I place the
said boilers side by side, and provide each with a furnace in the front
of the boiler, and place a lateral one on that side of each boiler un-
opposed to the other boiler.
Having now described the nature of my said Invention, and the
manner of carrying the same into effect, I wish it to be understood that
I do not limit myself to the precise methods of carrying the same into
effect herein described and represented in the accompanying Drawing,
as the same may be varied without departing from the nature of my
said Invention. I claim as my Invention, firstly, constructing steam
boilers in which the steam is generated either by the waste heat of a
puddling furnace or puddling furnaces, or by the heat of two or three
furnaces or fire-places situated at right angles to one another, as herein
described and represented in the accompanying Drawing.

page_text: Secondly, the method of circulating the heated air of steam boilers
and puddling furnaces through and around steam boilers herein
described and illustrated in the accompanying Drawing.
In witness whereof, I, the said Joshua Horton, have hereunto set
my hand and seal, this Twentieth day of December, in the year
of our Lord One thousand eight hundred and fifty-three.
Witness,
GEORGE SHAW.
