page_text: LETTERS PATENT to Ernest Lowc, of Holbeck, near Leeds, in the
County of York, and John Sandford Beatson, of Sheffield, in the
County of York, for the Invention of "IMPROVEMENTS IN MACHINERY
AND ADRADATIO MEDIAVER TA DIETY TRA "
PROVISIONAL SPECIFICATION left by the said Ernest Lowe and John
Sandford Beatson at the Office of the Commissioners of Patents,
with their Petition, on the 8th June 1874.
We, ERNEST LOWE, of Holbeck, near Leeds, in the County of York,
and JOHN SANDFORD BEATSON, of Sheffield, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY AND APPARATUS EMPLOYED IN PUDDLING IRON," to be as follows:-
Our improvements have reference to machinery for agitating the metal
during the "boiling process," and in apparatus employed therefor.
On a suitable foundation or framework we mount a tube or cylinder
similar to a cupola externally. The interior is lined with fire-brick. At

page_text: the bottom of the tube or apparatus and within it is providod an agitator
or splasher, to which is imparted a horizontal rotary motion from suitable
motive power.
The iron after being melted in a cupola of ordinary construction is
placed in the boiling apparatus herein-before described, suitable doorways t
or openings being provided for its admission. The agitator or splasher
is then caused to revolve and work amongst the metal until the metal is
in a proper state for the balling furnace. Suitable fuel is thrown into
the vessel for giving the required amount of heat for boiling.
After the above operation the metal is taken and put in the balling 1
furnace, and there operated upon in the ordinary manner.
The balling furnace is arranged so as to take in a large quantity of
iron, and is provided by preference with two fire-grates, one at each end,
also two sets of doorways at each side for the admission of the metal to
be operated upon.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ernest Lowe and John Sandford Beatson in the
Great Seal Patent Office on the 4th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ERNEST
Lowe, of Holbeck, near Leeds, in the County of York, and JOHN
SANDFORD BEATSON, of Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did for Herself, Her heirs and successors,
give and grant unto us, the said Ernest Lowe and John Sandford
Beatson, Her special licence that we, the said Ernest Lowe and John
Sandford Beatson, our executors, administrators, and assigns, or such
others as we, the said Ernest Lowe and John Sandford Beatson, 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

page_text: Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN MACHINERY AND APPARATUS EMPLOYED IN PUDDLING IRON," upon
the condition (amongst others) that we, the said Ernest Lowe and John
Sandford Beatson, our executors or administrators, by an instrument
in writing under our, or one of our 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 Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Ernest Lowe and John Sandford
Beatson, do hereby declare 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 of reference marked
thereon, that is to say :-
Our improvements have reference to machinery for agitating the metal
during the "boiling process," and in apparatus employed therefor.
On a suitable foundation or framework we mount a tube or.cylinder
similar to a cupola externally. The interior is lined with fire-brick. At
the bottom of the tube or apparatus and within it is provided an agitator
or splasher, to which is imparted a horizontal rotary motion from suitable
motive power.
The iron after being melted in a cupola of ordinary construction is
placed in the boiling apparatus herein-before described, suitable door-
ways or openings being provided for its admission. The agitator or
splasher is then caused to revolve and work amongst the metal until the
metal is in a proper state for the balling furnace. Suitable fuel is thrown
into the vessel for giving the required amount of heat for boiling.
After the above operation the metal is taken and put in the balling
furnace, and there operated upon in the ordinary manner.
The balling furnace is arranged so as to take in a large quantity of
iron, and is provided by preference with two fire-grates, one at each end,
also two sets of doorways at cach side for the admission of the metal to
5 be operated upon.

page_text: In order that our Invention may be more completely understood
reference is given to the two accompanying Sheets of Drawings, in
which Fig. 1, Sheet 1, is a vertical section; Fig. 2, a sectional plan
through A, B; Fig. 3, Sheet 2, a side elevation; Fig. 4, a plan looking
at the top.
On the foundation or framework a we mount a tube or cylinder b,
which may be similar to a cupola externally.
The interior in our Drawings is lined with fire-brick, as shewn at c,
but instead of this when preferred an inner lining of wrought iron may
be employed, as shewn in dotted lines d, the space between the external
cylinder 6 and the internal lining & being supplied with water from any
convenient source.
In order to admit the required blast of air (which may be obtained
from a fan or other known means) into the interior we provide any
required number of twyers e. At the bottom of the apparatus and
within it is provided an agitator or splasher f, which is formed prin-
cipally of fire-clay or fire-brick supported on a metal carrier f¹, which is
keyed on or otherwise fixed on the shaft h. To this a horizontal rotary
motion is imparted from suitable motive power and transmitted thereto
through the bevel wheels g and g¹. The shaft h which carries the bevel
wheel 9 and transmits the rotary motion to the agitator or splasher fis
by preference made hollow for lubricating “purposes and supplied with
the required amount of oil or water through the tube i, which passes
into the top of the shaft as shown. By this arrangement the bearings j
and may be kept well lubricated.
The iron after being well melted in a cupola is placed in the interior
of the apparatus b, and for the admission of the metal we provide the
opening through into the interior, which is made at any required angle.
Outside the opening is provided the trough or conductor m for receiving
the metal.
l
For the purpose of carrying off the gases we provide an opening o at
the top of the tube or cylinder b, which may be conducted into a suitable
chimney or flue.
After the boiling operation has been completed the metal is taken out
through the doorway n, shewn on Sheet 2, Figs. 3 and 4, and put into a
a balling furnace, and there operated upon in the ordinary manner.

page_text: Having now described the nature of the said Invention and the
manner, in which the same is to be performed, we would remark in con-
clusion that we do not limit ourselves to the exact limits, details, and
configuration of parts we have explained and shewn, as the same may of
course be varied or modified without in any way departing from the
nature of our said Invention; but what we do claim and desire to be
secured to us by Letters Patent is,
.
First. The arrangement, construction, and application of the tube or
cylinder b, substantially as and for purposes herein set forth.
Second. The arrangement, construction, and application of the agitator
or splasher f, substantially as and for purposes herein set forth.
Third. The arrangement and combination of the various parts forming
the machinery or apparatus, substantially as herein set forth.
In witness whereof, I, the said John Sandford Beatson, for myself
and on behalf of the said Ernest Lowe, havo hereunto set my
hand and scal, this Thirticth day of November, in the year of
our Lord One thousand eight hundred and seventy-four.
