IMPROVEMENTS IN THE MANU- FACTURE OF METAL TUBES
Year: 1876

page_text: LETTERS PATENT to Thomas Pugh Allen, of West Bromwich, in the County of
Stafford, Ironmaster, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF METAL TUBES."
Sealed the 14th March 1876, and dated the 1st January 1876.
PROVISIONAL SPECIFICATION left by the said Thomas Pugh Allen at the
Office of the Commissioners of Patents, on the 1st January 1876.
THOMAS PUGH ALLEN, of West Bromwich, in the County of Stafford, Iron-
master. "IMPROVEMENTS IN THE MANUFACTURE OF METAL TUBES."
This Invention refers to certain additions to and improvements upon a former
Invention of mine to which Her Majesty's Royal Letters Patent, dated 28th April
AD., 1875, No. 1562, have been granted to me, and it consists in continuing the
manufacture of the tube from the skelp stage to the welding without allowing it to
cool, so that by this means I produce a tube from the puddle bar without allowing
the metal to get cold, thereby saving the waste of reheating. To effect this I
employ a furnace in front of the last skelp rolls, and a pair of welding rolls or tongs
in front of the furnace, so that the metal in the form of a skelp as it leaves the
skelp rolls, being nearly but not quite hot enough for welding, enters and passes
through a sharp furnace just sufficiently to restore the lost heat, and thence into
welding rolls or tongs by which it is welded, thus the waste of reheating between
the skelp stage and welding is avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Pugh Allen in the Great Seal Patent Office on the 1st July
1876.
THOMAS PUGH ALLEN, of West Bromwich, in the County of Stafford, Ironmaster.
"IMPROVEMENTS IN THE MANUFACTURE OF METAL TUBES.'
This Invention refers to certain additions to and improvements upon a former
Invention of mine for which Her Majesty's Royal Letters Patent, dated the Twenty-
eighth day of April, in the year of our Lord One thousand eight hundred and
[Price 2d1

page_text: seventy-five, have been granted to me, and it consists in continuing the manu-
facture of the tube from the skelp stage to the welding without allowing it to cool,
so that by this means I produce a completely welded tube direct from the puddled
bar, thereby saving the waste of reheating. To effect this I employ a furnace in
front of the last skelp rolls and a pair of welding rolls or tongs in front of the
furnace, so that the metal in the form of a skelp as it leaves the skelp rolls being
nearly but not quite hot enough for welding enters and passes through a sharp
furnace just sufficiently to restore the lost heat, and thence into welding rolls or
tongs by which it is welded, thus the waste of reheating between the skelp stage
and welding is avoided.
Having thus described the nature of my said Invention and the manner in which
the same is to be carried into effect, I claim the within described improvements in
the manufacture of metal tubes by the employment of a furnace in front of the last
skelp rolls, with welding rolls or tongs in front of the furnace so as to avoid the
waste of reheating between the skelp stage and the welding.
In witness whereof, I, the said Thomas Pugh Allen, have hereunto set my hand
and seal, this Twenty-eighth day of June, in the year of our Lord One
thousand eight hundred and seventy-six.
THOMAS PUGH ALLEN.
