Year: 1869

page_text: LETTERS PATENT to Charles Sacrè, of Manchester, in the County of
Lancaster, Civil Engineer, Stanhopo Perkins, of Gorton, in the said
County, Engineer, and William Smellie, of the same Place, Forgo
Manager, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF WROUGHT IRON OR MALLEABLE METAL OF STEELY QUALITY."
Scaled the 14th April 1870, and dated_the 30th October 1869.
PROVISIONAL SPECIFICATION left by the said Charles Sacrè, Stanhope
Perkins, and William Smellie at the Office of the Commissioners
of Patents, with their Petition, on the 30th October 1869.
We, CHARLES SACRE, of Manchester, in the County of Lancaster,
Civil Engineer, STANHOPE PERKINS, of Gorton, in the said County,
Engineer, and WILLIAM SMELLIE, of the same Place, Forge Manager,
do hereby declare the nature of the said Invention for "IMPROVEMENTS

page_text: IN THE MANUFACTURE OF WROUGHT IRON OR MALLEABLE METAL OF STEELY
QUALITY," to be as follows:-
Our improvements consist in reducing wrought iron or other malleable
встар, in a cupola or other suitable melting furnace with or without an
admixture of pig iron, steel, or other metal, and in taking the metal thus
reduced while molten or when cold to a puddling furnace, to be puddled
in the ordinary manner, with or without common pig iron or other metal,
thereby producing a superior wrought iron or malleable metal of steely
quality.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Sacrè, Stanhope Perkins, and William
Smellie in the Great Seal Patent Office on the 29th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
SACRE, of Manchester, in the County of Lancaster, Civil Engincer,
STANHOPE PERKINS, of Gorton, in the said County, Engineer, and
WILLIAM SMELLIE, of the same Place, Forge Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of October, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Charles Sacrè, Stanhope Perkins, and William
Smellie, Her special license that we, the said Charles Sacrè, Stanhope
Perkins, and William Smellie, our executors, administrators, and
assigns, or such others as we, the said Charles Sacrè, Stanhope Perkins,
and William Smellic, 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 "IMPROVEMENTS IN THE MANUFACTURE OF WROUGHT IRON OR
MALLEABLE METAL OF STEELY QUALITY," upon the condition (amongst
others) that we, the said Charles Sacrè, Stanhope Perkins, and William
Smellie, by an instrument in writing under our hands and seals, or
under the hand and seal of one of us, should particularly describe and

page_text: 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 we, the said Charles Sacrè, Stanhope Perkins,
and William Smellie, 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 (that is to
say) -
Our improvements consist in reducing wrought iron or other malleable
scrap in a cupola or other suitable melting furnace, with or without an
admixture of pig iron, steel, or other metal, and in taking the metal thus
reduced while molten or when cold to a puddling furnace, to be puddled
in the ordinary manner, with or without common pig iron or other metal,
thereby producing a superior wrought iron or malleable metal of stecly
quality.
"
The manner in which we prefer to carry our Invention into effect to
produce the best quality of wrought iron such as will roll direct from the
"puddle bar" into plates, bars, angle iron, rails, or headings for rails for
railways, or any other shape is as follows:-We charge about eleven
hundredweights (11 cwts.) of wrought iron or wrought iron". scrap
together with about ten hundredweights (10 cwts.) of number one pig iron
of commerce into a cupola or other melting furnace, and when reduced
it is run out, and then broken when cold, the produce being about onc
ton of metal. Then we charge into the puddling furnace about three
hundred and eight pounds (308 lbs.) of the metal produced as above
described, one hundred and twelve pounds (112 lbs.) of No. 1 pig iron of
commerce and twenty-eight pounds (28 lbs.) of the spiegel eisen of
commerce. This mixture is puddled in the ordinary manner and produces
the best quality of wrought or malleable iron. The proportions above
named as well as the quality of the pig iron may be varied, but we prefer
the proportions and quality of metal specified. By our Invention we obtain
a better quality of wrought iron at less expense, and in greater quantity
from the same weight of wrought iron scrap than can be produced by the
ordinary process of "piling" and welding wrought iron scrap.
We have now particularly described the nature of our Invention and
the mode of carrying it into effect, and claim as our Invention, the

page_text: mode or process of manufacturing wrought iron or malleable metal,
substantially as herein-before described.
In witness whereof, we, the said Charles Sacrè, Stanhope Perkins,
and William Smellic, have hereunto set our hands and seals,
this Twenty-eighth day of April, in the year of our Lord Onc
thousand cight hundred and seventy.
CHARLES SACRÉ.
