Year: 1857

page_text: LETTERS PATENT to John James Russell, of Wednesbury, and Joseph
Bennett Howell, of Sheffield, for the Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF STEEL TUBES, APPLICABLE TO THE FLUES OF STEAM
BOILERS AND OTHER USES."
Sealed the 20th March 1857, and dated the 8th January 1857.
PROVISIONAL SPECIFICATION left by the said John James Russell and
Joseph Bennett Howell at the Office of the Commissioners of Patents,.
with their Petition, on the 8th January 1857.
We, JOHN JAMES RUSSELL, of Wednesbury, and JOSEPH BENNETT HOWELL,
of Sheffield, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF STEEL TUBES, APPLICABLE TO THE FLUES OF STEAM BOILERS
AND OTHER USES," to be as follows:-
This Invention has for its object improvements in the manufacture of steel
tabes, applicable to the flues of steam boilers and other uses; and the
improvements consist in causing the steel, after it has been converted in the
ordinary manner, to be rolled into sheets of the width, length, and thickness
required, then to cut the elges into the proper form, according as a lap or butt
weld is to be made. The sheets thus prepared are then turned up, so that
the edges meet, or nearly so, and when raised to a welling heat the welding of
the edges is performed by external pressure, by dies or by grooved rollers,
with or without the aid of internal supports or mandrils.

by the said John James Russell and Joseph Bennett Howell in the Great
Seal Patent Office on the 2nd July 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
JAMES RUSSELL, of Wednesbury, and JOSEPH BENNETT HOWELL, of Sheffield,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of January, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John James Russell and Joseph Bennett Howell, Her special licence that we,
the said John James Russell and Joseph Bennett Howell, our executors,
administrators, and assigns, or such others as we, the said John James Russell
and Joseph Bennett Howell, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF STEEL TUBES, APPLICABLE TO THE FLUES OF STEAM
BOILERS AND OTHER USES," upon the condition (amongst others) that we, the
said John James Russell and Joseph Bennett Howell, our exccutors 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 John James Russell, on behalf of
myself and the said Joseph Bennett Howell, do hereby declare the nature
of the said Invention, and in what manner the same is to be preformed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:
This Invention has for its object improvements in the manufacture of steel
tubes, applicable to the flues of steam boilers and other uses; and the
improvements consist in causing the steel, after it has been converted in the
ordinary manner, to be rolled into sheets of the width, length, and thickness
required, then to cut the edges into the proper form, according as a lap or butt
weld is to be made. The sheets thus prepared are then turned up so that

page_text: the edges meet, or nearly so, and when raised to a welding heat the welding of
the edges is performed by external pressure, by dies or by grooved rollers,
with or without the aid of internal supports or mandrils.
Ilaving thus stated the nature of our said Invention, we will proceed more
fully to describe the manner of performing the same.
For these purposes, the iron having been converted into wrought steel is to be
rolled into sheets of the desired thickness, as when preparing wrought iron for
making welded iron tubes, and suitable for making lap or butt joints or welds.
The wrought steel is then heated to a suitable welding heat, when they are to
be subjected to external circumferencial pressure, either by being drawn
through dies or by means of grooved rollers, with or without the internal
support of a mandril, as when welding wrought-iron tubes.
What we claim is the manufacture of wrought-steel welded tubes, applicable
to the flues of steam boilers and other uses..
In witness whereof, I, the said John James Russell, have hereunto set
my hand and seal, this First day of July, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness,
Jos. SMITII,
Handsworth..
