page_text: LETTERS PATENT to George William Hawksley, Matthew Wild, and Joseph
Astbury, all of Sheffield, in the County of York, for the Invention of "A
NEW AND IMPROVED ARRANGEMENT OF FURNACE TO BE APPLIED TO STEAM
BOILERS, WHICH IS ALSO APPLICABLE FOR OTHER PURPOSES.
Sealed the 5th January 1867, and dated the 11th July 1866.
PROVISIONAL SPECIFICATION left by the said William Hawksley,
Matthew Wild, and Joseph Astbury at the Office of the Commissioners
of Patents, with their Petition, on the 11th July 1866.
We, GEORGE WILLIAM HAWKSLEY, MATTHEW WILD, and JOSEPH ASTBURY,
all of Sheffield, in the County of York, do hereby declare the nature of the
said Invention for "A NEW AND IMPROVED ARRANGEMENT OF FURNACE TO BE
APPLIED TO STEAM BOILERS, WHICH IS ALSO APPLICABLE FOR OTHER PURPOSES," to be
as follows:-
Our Invention consists in an arrangement and construction of furnace to be
applied to the tubes or internal parts of boilers now used for generating steam,
or to water jackets. This novel arrangement is to be employed for various
purposes, such as "puddling" and boiling metals or for boiling or heating
other materials or substances, the flue or internal arrangement of the boiler or
the water jacket being constructed and adapted to the various dimensions
necessary to receive such furnaces, which are so arranged that the various
operations for which they may be required can be effected conveniently from
the outside. For example, to adapt a furnace for the purpose of puddling

page_text: metal and simultaneously generating steam in the boiler, the furnace would
be so constructed that the portion or space behind the "bridge" may be
rendered available for such purpose, for which object two openings would be
made in the side of the boiler (instead of one opening at the end as usual) one
of these openings would be made in front of the bridge and communicates
with the furnace for supplying fuel thereto, and the other would be made at
a point behind the bridge of the furnace, and communicates with the space or
chamber containing the metal to be puddled, and through which opening the
said operation would be carried on, or through which any other required
operation may be conducted, both openings being closed by doors if necessary.
The nature and chief feature of the Invention being the peculiar adaptation
and combination of furnaces with boilers so that the heat from such furnaces
may be simultaneously available for boiling or heating metals (or for boiling
or heating other materials) and for generating steam in the boiler containing
the furnace; for which purposes the furnace and boiler are peculiarly con-
structed as before described.
Secondly, our Invention consists in an arrangement of tubes placed under
the bottom or side plates (or both) of the puddling chamber of the furnace,
through which water circulates, such arrangement being employed and
designed to regulate the temperature of the said plates, the water being sup-
plied to the pipes from any cold water tank, and is caused to pass through the
tubes by pressure in any ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Hawksley, Matthew Wild, and Joseph Astbury, in
the Great Seal Patent Office on the 11th January 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
WILLIAM HAWKSLEY, MATTHEW WILD, and JOSEPH ASTBURY, all of Sheffield,
in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of July, in the year of our Lord One
thousand eight hundred and sixty-six, in the thirtieth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto us, the said
George William Hawksley, Matthew Wild, and Joseph Astbury, Her special
license that we, the said George William Hawksley, Matthew Wild, and
Joseph Astbury, our executors, administrators, and assigns, or such others as
we, the said George William Hawksley, Matthew Wild, and Joseph Astbury,

page_text: 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 "A NEW AND IMPROVED ARRANGE-
MENT OF FURNACE TO BE APPLIED TO STEAM BOILERS, WHICH IS ALSO APPLICABLE FOR
OTHER PURPOSES," upon the condition (amongst others) that we, the said
George William IIawksley, Matthew Wild, and Joseph Astbury, our executors
or administrators, by an instrument in writing under our, or one of our, or
their, or one of their hands and seals, should particularly describe and ascer-
tain 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 aud immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said George William Hawksley, 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 follow-
ing statement and accompanying Drawings (that is to say):-
Our Invention consists in an arrangement and construction of furnace to
be applied to the boilers or internal parts of boilers now used for generating
steam or to water jackets. This novel arrangement is to be employed for
various purposes, such as "puddling" and boiling metals, or for boiling or
heating other materials or substances, the flue or internal arrangement of the
boiler or the "water jacket" being constructed and adapted to the various
dimensions necessary to receive such furnaces, which are so arranged that the
various operations for which they may be required can be effected conveniently
from the outside. For example, to adapt a furnace for the purpose of puddling
metal, and simultaneously generating steam in the boiler, the furnace would
be so constructed that the portion or space behind the "bridge" may be
rendered available for such purpose, for which object two openings would be
made in the side of the boiler (instead of one opening at the end as usual) one
of these openings would be made in front of the bridge, and communicates
with the furnace for supplying fuel thereto, and the other would be made at a
point behind the bridge of the furnace and communicates with the space
chamber containing the metal to be puddled, and through which opening the
said operation would be carried on through which any other required open
action may be conducted, both openings being closed by doors if necessary.
The nature and chief feature of the Invention being the peculiar adaptation
and combination of furnaces with boilers so that the heat from such furnace

page_text: may be simultaneously available for boiling or heating metals (or for boiling
or heating other materials) and for generating steam in the boiler containing
the furnace, for which purposes the furnace and boiler are peculiarly con-
structed as before described.
Secondly, our Invention consists in an arrangement of tubes placed under
the bottom or side plates (or both) of the puddling chamber of the furnace,
through which water circulates, such arrangement being employed and
designed to regulate the temperature of the said plates, the water being sup-
plied to the pipes from any cold water tank, and is caused to pass through the
tubes by pressure in any ordinary manner.
In order that the Invention may be better understood and explained in
detail we have hereunto attached a Sheet of Drawings made upon a scale of
about half an inch to the foot, similar letters of referenee being marked
upon corresponding parts on all the Figures alike.
Fig. 1 represents a longitudinal sectional elevation of a steam boiler, or
generator to the flue or internal portion thereof, the puddling or metal boiling
furnace is shewn applied; this view illustrates more particularly the peculiar
arrangement and adaptation of a puddling furnace to the internal portion of
the boiler. Fig. 2 represents a transverse section of the same through the
line A, B. Fig. 3 represents an example of the same principle of combining
boiler and furnace together, but in this arrangement the boiler is supplied with
two furnaces instead of one Fig. 4 being a transverse section of the same
taken below the budge through the line C, D. Fig. 5 represents another
example or arrangement of furnace in which the heat after leaving the puddling
furnace is passed through a diminishing tube forming a flue inside the boiler
before being received by the chimney. Fig. 6 represents a transverse section
of the same through the line E, F, and Figs. 7 and 8 represent respectively a
longitudinal sectional plan view and a transverse sectional elevational view of
another arrangement of boiler and puddling furnace in which the heat of the
furnace is utilized for the purpose of heating long bars of metal. We would
bere remark that these Figures and views are shewn as examples, as the com-
bination of a puddling furnace with a steam boiler may be arranged in various
ways. In the various Figures a, a, is the outer shell of the boiler, and b, b,
the furnace or chamber, which is constructed and adapted for the purpose of
puddling, or boiling, or heating metal, and simultaneously generating steam;
the fuel is fed into the furnace below the bridge through the aperture c formed
in the side of the boiler, and the opening d communicates with the space or
chamber e containing the metal to be puddled or heated, through which open-
ing the operation of puddling is to be carried on, or through which any other

page_text: similar operation may be effected, the gasses or products of combustion escaping
from the puddling furnace pass through the flue g which may either be con-
structed as shewn in Fig. 1, or such flue may be elongated and having a
diminishing diameter as shewn in Fig. 5. The bottom or sides of the furnace or
puddling chambers may be supplied with series of serpentine pipes as seen in
Fig. 1 through which cold water is caused to circulate by pumps or otherwise
for the purpose of regulating the temperature of the plates composing the sides
or bottom of the furnace as before described. The arrangement of furnace as
shewn in Figs. 7 and 8 are more particnlarly constructed and adapted for the
purpose of heating bars or lengths of metal which are placed in the chamber
or receptacle h, through the opening at the front of the boiler, the fuel being
fed in at the openings i, i.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim,-
First, combining and employing furnaces for puddling or heating metals with
boilers for generating steam, so that the heat employed for generating steam
may also be used and utilized for the puddling or heating of metals, and we
would remark that the form or construction of both boiler and furnace may
be varied in numerous ways.
Secondly, the application of a series of pipes for the circulation of water to
maintain the due temperature of the bottom and sides of the puddling furnace,
as herein-before described, set forth, and fully illustrated in the Drawings
attached.
In witness whereof, I, the said George William Hawksley, have hereunto
set my hand and seal, this Ninth day of January, in the year of our
Lord One thousand eight hundred and sixty-seven.
GEORGE WILLIAM HAWKSLEY. (L.S.)
