IMPROVE- MENTS IN PREPARING THE ENDS OF WELDED TUBES PREVIOUS TO THEIR BEING FIXED IN PLATES
Year: 1861

page_text: LETTERS PATENT to John James Russell, of the Crown Tube Works,
Wednesbury, Patent Tube Manufacturer, for the Invention of "IMPROVE-
MENTS IN PREPARING THE ENDS OF WELDED TUBES PREVIOUS TO THEIR BEING
FIXED IN PLATES."
Sealed the 31st January 1862, and dated the 6th September 1861..
PROVISIONAL SPECIFICATION left by the said John James Russell at
the Office of the Commissioners of Patents, with his Petition, on the
6th September 1861.
I, JOHN JAMES RUSSELL, of the Crown Tube Works, Wednesbury, Patent
Tube Manufacturer, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN PREPARING THE ENDS OF WELDED TUBES PREVIOUS TO THEIR
BEING FIXED IN PLATES," to be as follows:-
This Invention has for its object improvements in preparing the ends of
welded tubes previous to their being fixed in plates. For these purposes, in
order that the ends of welded iron tubes, which are used in the construc-
tion of the flues of tubular boilers and for other purposes, may be more
uniformly and advantageously annealed, in order that such ends may be
expanded and caused to fit the holes in the plates in which they may be
applied, I, in place of heating them as heretofore, employ a bath of fluid
lead or other suitable metal or alloy, into which the ends of the welded tubes
are immersed, and by this means they are readily and very uniformly heated

page_text: to the extent desired, which caunot be the case when a fire is used. The ends
of the tubes having been immersed in the fluid metal bath to the extent
desired and heated thereby, are then forced into powdered coke, or charcoal,
or sand, or other suitable matter to exclude the atmosphere whilst the ends
are becoming cold.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John James Russell in tho Great Seal Patent Office on
the 6th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JAMES RUSSELL, of the Crown Tube Works, Wednesbury, Patent Tubo Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of September, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John James Russell, Her special licence that I, the said
John James Russell, my executors, administrators, and assigns, or such
others as I, the said John James Russell, my 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 PREPARING THE ENDS OF WELDED
TUBES PREVIOUS TO THEIR BEING FIXED IN PLATES," upon the condition (amongst
others) that I, the said John James Russell, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, 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, do hereby declare
the nature of tho said Invention, and in what manner the same is to be
performed, 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 preparing the ends of
wolded tubes previous to their being fixed in plates. For these purposes, in

page_text: order that the ends of welded iron tubes, which are used in the construc-
tion of the flues of tubular boilers and for other purposes, may be more
uniformly and advantageously annealed, in order that such ends may be
expanded and caused to fit the holes in the plates in which they may be
applied, I, in place of heating them as heretofore, employ a bath of fluid lead
or other suitable metal or alloy, into which the ends of the welded tubes are
immersed, and by this means they are, readily and very uniformly heated to
the extent desired, which cannot be the case when a fire is used. The ends of
the tubes having been immersed in the fluid metal bath to the extent desired
and heated thereby, are then forced into powdered coke, or charcoal, or sand,
or other suitable matter to exclude the atmosphere whilst the ends are.
becoming cooled.
In witness whereof, I, the said John James Russell, have hereunto
set my hand and seal, this Fifth day of March, in the year of our
Lord Oue thousand eight hundred and sixty-two.
J. J. RUSSELL. (L.)
