Year: 1872

page_text: LETTERS PATENT to Henry Ourrer Briggs and David Ramsay
Ramsay, both of Saltburn by the Sea, in the County of York,
Iron Masters, for the Invention of "IMPROVEMENTS IN STEAM
GENERATING AND HEATING APPARATUS TO BE USED IN CONNECTION WITH
ROTATORY OR OTHER PUDDLING FURNACES."
PROVISIONAL SPECIFICATION left by the said Henry Currer Briggs
and David Ramsay Ramsay at the Office of the Commissioners of
Patents, with their Petition, on the 20th April 1872.
We, HENRY OURRER BRIGGS and DAVID RAMSAY RAMSAY, both of
Saltburn by the Sea, in the County of York, Iron Masters, do hereby
declare the nature of our said Invention for "IMPROVEMENTS IN STEAM
GENERATING AND HEATING APPARATUS TO BE USED IN CONNECTION WITH ROTATORY
OR OTHER PUDDLING FURNACES," to be as follows :—
This Invention relates to a peculiar construction, arrangement, and
combination of steam generator and combined furnace and combustion
chamber to be used in connection with a rotatory or other puddling

page_text: furnace, whereby provision is made for utilizing the waste heat from the
puddler when the puddling furnace is in operation, and for the heating
of the steam generator by a separate and independent furnace, if desired,
when the puddler is out of action or is disconnected from the combustion
chamber.
The combustion chamber consists of an outer casing of boiler plato
lined with fire-brick, and provided with grate bars and a fire-door of its
own. On one side of this chamber there is constructed a projecting
neck also lined with fire-brick, and provided with a self-closing sliding
or hinged door or damper which closes the entrance to the combustion:
chamber the moment the moveable neck of the puddling chamber is
withdrawn, and prevents access of cold air to the steam generator which
rests upon the top of the combustion chamber.
The steam generator consists of a vertical boiler composed of an inner
and outer shell with an annular water space between the two.
The
inner shell is traversed in different directions by a number of water
tubes placed either horizontally or at a slight inclination, and opposito
each end of each tube thero is fitted in the outer shell a hand holo
with tightly-fitting cover for the convenience of cleaning the tubes. The
upper part of the inner shell may be of rather smaller diameter than ;
the part containing tho tubes, and the upper part of this contracted
portion which is above the water level is lined with fire-brick, and
communicates directly with the chimney. Hand holes are also provided
round the outer shell near the bottom thereof, also a mud cock for
facilitating the removal of the deposit from the bottom of the boiler.
When the self-closing door or damper is shut and the puddler is dis-
connected or out of action, the combustion chamber may be used as a
separate furnace for the steam generator, but when the puddler is in
action then the generator may be heated entirely by the waste heat
from the puddling furnace.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Currer Briggs and David Ramsay Ramsay
in the Great Scal Patent Office on the 18th October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
CURRER BRIGGS and DAVID RAMSAY RAMSAY, both of Saltburn by the
Sca, in the County of York, Iron Masters, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the of
our Lord One thousand eight hundred and seventy-two, in the 35th
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Henry Currer Briggs and David Ramsay
Ramsay, Her special license that we, the said Henry Currer Briggs and
David Ramsay Ramsay, our executors, administrators, and assigns, or
such others as we, the said Henry Currer Briggs and David Ramsay
Ramsay, our executors, administrators, or 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,
usc, 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 GENERATING AND HEATING APPARATUS TO BE USED
3 IN CONNECTION WITH ROTATORY PUDDLING FURNACES," upon the condition
(amongst others) that we, the said Henry Currer Briggs and David
Ramsay Ramsay, our executors or administrators, 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 Office within
six calendar months next and immediately after the date of the said
Letters Patent.
J
NOW KNOW YE, that we, the said Henry Currer Briggs and David
Ramsay Ramsay, do hereby declaro the nature of our said Invention,
and in what. manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings, and to the letters and figures
marked thereon, that is to say :—
Our said Invention relates to. the combination of a steam generator
with a combined furnace and combustion chamber to bo used in con-
nection with a rotatory or other puddling furnace (by preference tho
Danks" puddler), whereby provision is made for utilizing the wasto
heat from the puddler when the puddling furnace is in operation, and
for the heating of the steam generator by a separate and independent
furnace, if desired, when the puddler is out of action or is disconnected
from the combustion chamber.

page_text: And in order that our said Invention may be fully understood, we
shall now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed Sheet of
Drawings, the same letters of referenco indicating corresponding parts
in all the Figures.
Figure 1 of our Drawings represents a vertical section of our arrange-
ment of steam generator and combined furnace and combustion chamber
to be applied to and used with a rotatory or other puddling furnace ;
and Figure 2 is a horizontal section taken through the combined
combustion chamber and furnace along the line 1-2; and Figure 3
is a similar section taken through the generator itself along the
line 3-4.
The combustion chamber A consists of an outer casing a of boiler
plate lined with fire-brick b, and provided with grate bars B and a fire-
door O of its own. On one side of this chamber there is constructed a
projecting neck or flue D, also lined with fire-brick, as shewn, and pro-
vided with a self-closing sliding or hinged door or damper E which
closes the entrance to the combustion chamber (by the action of the
counterweight F) the moment the movable neck of the puddling
chamber is withdrawn, and prevents access of cold air to the steam
generator which rests upon and is bolted to the top of the combustion
'chamber, or the combustion chamber may be formed in one with the
generator by carrying down the outer shell & thereof. The steam
generator G consists by preference of a vertical boiler composed of an
inner and outer shell c and d with an annular water space e between
the two. The inner shell c is traversed in different directions by a
number of water tubes II placed either horizontally or at slight inclina-
tion, and opposite each end of each tube there is fitted in the outer
shell a hand holo with tightly fitting cover f for the convenience of
elcaning the said tubes. These tubes may be placed either in the
uptake only, or in both the uptake and the steam chamber. The upper
part of the inner shell may be of rather smaller diameter than the part
containing the tubes, and the upper part of this contracted portion
which is above the water level is lined with fire-brick, as shown
at g, and communicates directly with the chimney. Hand holes arc
also provided round the outer shell near the bottom thereof, also a mud
cock for facilitating the removal of the deposit from the bottom of the

page_text: boiler. When the self-closing door or damper E is shut and the puddler
is disconnected or out of action the combustion chamber A may be
used as a separate furnace for the steam generator G, but when the
puddler is in action then the generator may be heated entirely by the
waste heat from the puddling furnace.
The ash-pit hole of the combined combustion chamber and furnace
should be fitted with a door or damper to regulate the admission
of air.
We would here observe that we do not claim the peculiar construction
of steam generator, nor its employment separate and apart from the
combined combustion chamber and furnace A.
Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that what we consider
to be novel and original, and therefore claim as the Invention secured to
us by the herein-before in part recited Letters Patent is, the combination
of a steam generator with a combined furnace and combustion chamber,
such chamber being provided with a projecting neck fitted with a self-
closing door or damper, and being further provided with a fire-grate
and firing door, to enable it to be heated either by the waste heat
from a rotatory or other puddling furnace, or by a fire of its own,
substantially as and for the purpose herein-before described..
'
In witness whereof, I, the said Henry Currer Briggs, on behalf of
myself and the said David Ramsay Ramsay, have to this our
Specification set my hand and seal, the Eleventh day of October
One thousand eight hundred and seventy-two.
