Year: 1875

page_text: LETTERS PATENT to Thomas Gidlow and James Abbott, both of
the Gidlow Coal and Iron Works, Ince, near Wigan, in the County
of Lancaster, for the Invention of "AN IMPROVED ARRANGEMENT OF
Sealed the 3rd August 1875, and dated the 23rd February 1875.
PROVISIONAL SPECIFICATION left by the said Thomas Gidlow and
James Abbott at the Office of the Commissioners of Patents, with
their Petition, on the 23rd February 1875.
We, THOMAS GIDLOW and JAMES ABBOTT, both of the Gidlow Coal
and Iron Works, Ince, near Wigan, in the County of Lancaster, both
do hereby declare the nature of the said Invention for "AN IMPROVED
ARRANGEMENT OF STEAM BOILER IN CONJUNCTION WITH METALLURGICAL FURNACES,”
to be as follows:-
Our Invention relates to the arrangement of a steam boiler in con-
junction with metallurgical furnaces in such a manner as to utilise more
completely than has hitherto been done the heat of the flame and

page_text: products escaping from the furnaces, to afford ready means of regulating
the draught, and to effect the consumption of the smoke.
For this purpose we construct two furnaces, such as puddling or
heating furnaces, side by side, and above them we place a horizontal
cylindrical steam boiler having two internal flues. We support the said
boiler on columns or open framework so as to leave the space beneath it
sufficiently clear for access to work, repair, or replace the furnaces. At
the end of the two furnaces we construct an uptake divided by a mid-
feather so as to separate it into two channels or flues by which the flame
and products escaping from the furnaces are conducted into the two flues
of the boiler, the products from each furnace being thus led into one of
these boiler flues. At the opposite end of the boiler we erect the
chimney or shaft, preferably on columns or open framework, and form a
divided flue or channel into it from the two boiler flues, fitting the same
with dampers. By this arrangement the flame and hot products from
either furnace or from both are made to give out their heat to the water
in the boiler on their way to the chimney, and are thus to a great extent
cooled before they reach the dampers. The waste heat is thus utilised
for the generation of steam in the boiler, and the dampers are con-
veniently accessible in a position where they are not liable to be damaged
by excessive heat.
In the uptake from the furnaces to the boiler we prefer to provide
apertures fitted with valves or dampers by which a regulated quantity of
air can be admitted to mingle with the hot products from the furnaces,
thus affording the supply of oxygen necessary for the consumption of
the smoke, and utilising the heat therefrom in the boiler flues.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Gidlow and James Abbott in the Great
Seal Patent Office on the 21st August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS 30
GIDLOW and JAMES ABBOTT, both of the Gidlow Coal and Iron Works,
Ince, near Wigan, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of February, in the

page_text: year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Thomas Gidlow and James
Abbott, Her special license, that we, the said Thomas Gidlow and James
6 Abbott, our executors, administrators, and assigns, or such others as
we, the said Thomas Gidlow and James Abbott, our executors, admini-
strators, 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 IMPROVED ARRANGEMENT
OF STEAM BOILER IN CONJUNCTION WITH METALLURGICAL FURNACES," upon the
condition (amongst others) that we, the said Thomas Gidlow and James
Abbott, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one
of us or them, 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 Thomas Gidlow, on behalf of
myself and the said James Abbott, 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, reference being had to the accompanying Sheet of
Drawings, and to the figures and letters marked thereon, that is to
say:―
Our Invention relates to the arrangement of a steam boiler in con..
junction with metallurgical furnaces in such a manner as to utilise more
completely than has hitherto been done the heat of the flame and
products escaping from the furnaces, to afford ready means of regulating
the draught, and to effect the consumption of the smoke.
For this purpose we construct two furnaces, such as puddling or
heating furnaces, side by side, and above them we place a horizontal.
cylindrical steam boiler having two internal flues. We support the said.
boiler on columns or open framework so as to leave the space beneath it,
sufficiently clear for access to work, repair, or replace the furnaces. At

page_text: the end of the two furnaces we construct an uptake divided by a mid-
feather so as to separate it into two channels or flues by which the flame
and products escaping from the furnaces are conducted into the two flues
of the boiler, the products from each furnace being thus led into one of
these boiler flues. At the opposite end of the boiler we erect the
chimney or shaft, preferably on columns or open framework, and form a
divided flue or channel into it from the two boiler flues, fitting the same
with dampers. By this arrangement the flame and hot products from
either furnace or from both are made to give out their heat to the water
in the boiler on their way to the chimney, and are thus to a great extent
cooled before they reach the dampers. The waste heat is thus utilized
for the generation of steam in the boiler, and the dampers are con-
veniently accessible in a position where they are not liable to be damaged
by excessive heat.
In the uptake from the furnaces to the boiler flues we prefer to
provide apertures fitted with valves or dampers by which a regulated
quantity of air can be admitted to mingle with the hot products from the
furnaces, thus affording the supply of oxygen necessary for the con-
sumption of the smoke and utilising the heat therefrom in the boiler
flues
Fig. 1 shews a plan, Fig. 2 a side elevation, and Fig. 3 an end
elevation of our before-described improved arrangement of metallurgical
furnaces in combination with a steam boiler. A, A', are two furnaces,
such as puddling furnaces; B is the uptake divided by a midfeather B¹
into two vertical flues, through which the flames from the furnaces pass
separately into two cylindrical flues C, O³, in the horizontal steam boiler
C, which 'is supported upon columns D above the furnaces A, A¹, and
the flues of which communicate at the back end with the stack or
chimney E, also carried by the columns D. The lower part of the stack
or chimney is also divided by a midfeather E' into two separate flues
with which the boiler flues communicate separately. Dampers F, F, are
provided between the boiler flues and the chimney, by means of which
the draught is regulated and apertures provided with valves or dampers
are by preference provided in the uptake B for the admission of air to
effect the consumption of smoke, as before described, and the dampers
F may also be arranged to admit a further quantity of air through side

page_text: openings into the chimney E in order more completely to consume the
smoke when the flames issuing from the flues meet at the top of the
midfeather E'.
Having thus described the nature of our Invention and in what
manner the same is to be performed, we claim the before-described
arrangement of two or more metallurgical furnaces in combination with
a steam boiler, the flames from the furnaces being made to ascend
through separate flues in an uptake into separate horizontal flues in the
steam boiler, whence they issue into a chimney divided at its lower end
by a midfeather into separate passages.
In witness whereof, I, the said Thomas Gidlow, have hereunto
set my hand and seal, this Twentieth day of August, in the
year of our Lord One thousand eight hundred and seventy-
five.
