NEW OR IMPROVED METALLIC TUBES
Year: 1853

page_text: LETTERS PATENT to Amédée François Rémond, of Birmingham, in the
County of Warwick, Gentleman, for the Invention of "NEW OR IMPROVED
METALLIC TUBES."
Sealed the 22nd February 1854, and dated the 29th December 1853.
PROVISIONAL SPECIFICATION left by the said Amédée François Rémond
at the Office of the Commissioners of Patents, with his Petition, on the
29th December 1853.
I AMÉDÉE FRANÇOIS RÉMOND of Birmingham in the County of Warwick
Gentleman do hereby declare the nature of the said Invention for "NEW OR
IMPROVED METALLIC TUBES " to be as follows:-
My Invention consists in making tubes of iron copper brass or other
metal or alloy with corrugations therein the said corrugations lying in planes
perpendicular to the axis of the tubes; that is to say the corrugations do not
extend from end to end of the tube but are transverse or pass round the tube.
The said tubes may either be of a circular or an elliptical section. The said
tubes are made by rolling two strips of metal between rolls of a shape proper
to give to the said strips a semi-cylindrical or semi-elliptical figure (section)
and at the same time make the transverse undulations or corrugations therein.
The two half tubes are then joined together by soldering and rivetting or
welding according to the metal of which they are made. I prefer to make
the edges of the said half tubes overlap when a cylindrical tube is made
but to be presented to each other face to face when an elliptical tube is
made in which latter case two feathers or edges are formed along the whole
16023.

the tube and I sometimes apply the last-described method to cylindrical
tubes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Amédée François Rémond in the Great Seal Patent Office on
the 29th June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME I АMÉDÉR
FRANÇOIS REMOND of Birmingham in the County of Warwick Gentleman
send greeting
WHEREAS Her most Excellent Majesty Queen Victoria by Her Letters
Patent bearing date the Twenty-ninth day of December in the year of our
Lord One thousand eight hundred and fifty-three in the seventeenth year of
Her reign did for Herself Her heirs and successors give and grant unto me
the said Amédée François Rémond Her special licence that I the said
Amédée François Rémond my exccutors administrators and assigns or such
others as I the said Amédée François Rémond 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 Inven-
tion for "NEW OB IMPROVED METALLIC TUBES" upon the condition (amongst
others) that I the said Amédée François Rémond by an instrument in
writing under my hand and seal should particularly describe and ascertain the
nature of the said Invention and in what manner the same was to be per-
formed 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 Amédee François Remond do hereby
declare the nature of the said Invention and in what manuer the same is to
be performed to be particularly described and ascertained in and by the fol-
lowing statement thereof, (that is to say) :-
My said Invention consists in making metallic tubes with corrugations
therein the said corrugations being situated in planes perpendicular to the
axes of the said tubes, that is to say the corrugations do not extend from end
to end of the tube but are transverse or pass round the tube. The said tube
may either be of a circular or of an elliptical or other section. I make the

page_text: said tubes by rolling that is to say I pass strips of sheet metal of suitable
thickness between grooved rolls the grooves in the said rolls having the
transverse impressions necessary to produce the corrugations in the sheet
metal rolled between them. The strips of metal thus rolled constitute hollow
semi-cylinders having transverse undulations or corrugations. When two of
the said semi-cylinders or half tubes are joined together by their edges they
constitute a complete hollow cylinder or tube with continuous corrugations
passing round the same. Instead of forming the half tubes by rolling 1
sometimes form them by stamping. Tubes of an elliptical section are made in
the same way excepting that the necessary difference of figure is given to the
rolls. The method of joining the semi-cylinders or half tubes must be varied
according to the different metals or alloys of which the said tubes are made
as well as the sizes and figures of the said tubes. Where copper brass or
other alloy of copper is used in the manufacture of the said tubes I prefer to
join the two half tubes together by soldering and where iron is used in the
manufacture of the said tubes I prefer to use the processes of rivetting
or welding in joining the said half tubes. In making cylindrical tubes I
prefer to make the edges of the said half tubes overlap each other in which
case the said half tubes must be made of plates somewhat broader than is
necessary to make semi-cylinders of the required diameter so that when the
said half tubes are joined together they shall constitute a cylinder notwith-
standing the overlapping of the edges. In making elliptical tubes I prefer
making a flange or feather on the edges of the two half tubes of which each
of the said elliptical tubes is made which said flanges or feathers are presented
to each other face to face; when the edges of the two semi-ellipses are
brought together the said double flanges or feathers thus running along the
whole length of the tube at points opposite to each other in the longest
diameter of the ellipse present a very convenient arrangement for rivetting
welding or soldering the said half tubes together. I sometimes effect the
junction of the halves of cylindrical tubes by means of flanges or feathers as
described with regard to elliptical tubes. My Invention is applicable to tubes
of all sizes and made of all the various metals and metallic alloys of which
metallic tubes are or may be made. Although I prefer making tubes of two
pieces as described yet where tubes of large diameter are required I some-
times make the same of three or more pieces. Tubes made according to my
said Invention are applicable to the construction of steam boilers and various
other purposes.
Having now described the nature of my said Invention and the manner of
carrying the same into effect I wish it to be understood that I do not limit

page_text: myself to the precise methods herein described as the same may be varied
without departing from the nature of my said Invention but I claim as my
Invention making metallic tubes having corrugations in planes perpendicular
to the axes of the said tubes as herein described.
In witness whereof I the said Amédée François Rémond have hereunto
set my hand and seal this Twenty-eighth day of June in the year of
our Lord One thousand eight hundred and fifty-four.
