page_text: LETTERS PATENT to Burdett Lambton Brown, of the Wednesbury
Tube Works, Wednesbury, in the County of Stafford, for the
Invention of "AN IMPROVED MACHINE FOR STRAIGHTENING AND FINISHING
TUBES AND BARS."
PROVISIONAL SPECIFICATION left by the said Burdett Lambton Brown
at the Office of the Commissioners of Patents, with his Petition,
on the 5th December 1871.
I, BURDETT LAMBTON BROWN, of the Wednesbury Tube Works,
Wednesbury, in the County of Stafford, do hereby declare the nature
of the said Invention for "AN IMPROVED MACHINE FOR STRAIGHTENING AND
FINISHING TUBES AND BARS," to be as follows:-

page_text: are either of different diameters or driven at different surface speeds, and
by preference taper or conical, that is, one end being of larger diameter
than the other, so that when a tube or bar is placed in the angle betwixt
the three rollers, and rotary motion is given to them, their action upon
the said tube or bar has not only a rolling and thereby a straightening
effect, but a rubbing action, which consequently smooths the surface or
finishes it. Two of the said rollers are arranged horizontally, and
mounted in adjustable slide bearings, so as to be readily set to any
distance apart for different sizes of tubes or bars, either taper or parallel,
and the other roller is mounted in a moveable bearing above or over the
angle betwixt them, and acts by gravitation, but may be pressed by
weights or springs, and is capable of being lifted or raised by levers and
rods for the introduction of the tubes or bars to be operated upon, and
for the removal thereof.
SPECIFICATION' in pursuance of the conditions of the Letters Patent,
filed by the said Burdett Lambton Brown in the Great Seal Patent
Office on the 5th June 1872.

LAMBTON BROWN, of the Wednesbury Tube Works, Wednesbury, in the
County of Stafford, send greeting.
