AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OY ORNAMENTAL METALLIC TUBES.
Year: 1867

page_text: LETTERS PATENT to Thomas Weston, of Birmingham, in the County of
Warwick, Tube Maker, for the Invention of "AN IMPROVEMENT OR
IMPROVEMENTS IN THE MANUFACTURE OY ORNAMENTAL METALLIC TUBES.
PROVISIONAL SPECIFICATION left by the said Thomas Weston at the
Office of the Commissioners of Patents, with his Petition, on the 30th
September 1867.
I, THOMAS WESTON, of Birmingham, in the County of Warwick, Tube
Maker, do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT OR IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL METALLIC TUBES,"
to be as follows:-
My Invention consists of the improvement or improvements herein-after
described in the manufacture of ornamental metallic tubes, whereby economy
and simplicity of manufacture combined with strength and durability in the
tubes produced are secured. In the ordinary manufacture of ornamental
metallic tubes, a solid brass or other tube of the required thickness is passed
through ornamental rolls and its surface ornamented by the pressure of the said
rolls. Or a thin ornamental tube made in one piece or in several pieces pro-
duced by rolling or otherwise is secured by soldering or brazing or by collars
to a tubular foundation of iron.
In manufacturing ornamental metallic tubes according to my Invention, I
proceed in the following manner:-I take a tube or foundation of wrought

page_text: iron of the required strength, and I take another tube of thin brass and by
a drawing process conducted in the ordinary manner I coat or cover the said
tube or foundation of iron with the said thin tube of brass. The compound
tube thus produced is similar to the tubes known in commerce as cased tubes.
I take this compound tube and place in its interior a steel mandril and pass
the said compound tube supported upon its mandril through ornamental rolls
of the ordinary kind, the acting surfaces of the said rolls having engraved upon
them the pattern or ornament it is wished to impress upon the tube. By the
pressure to which the compound tube is subjected in its passage through the
rolls, the outer brass case or tube of the said compound tube is impressed
with the pattern or ornament upon the said rolls and an ornamental tube
thereby produced, the said ornamental tube resembling a solid brass ornamental
tube, whereas it is a compound tube, the interior being of iron and the exterior
of brass. Instead of employing a thin tube of brass as described for covering
the tube or foundation of iron a thin tube of copper or other metal or alloy
capable of being drawn upon a tube or foundation of iron and afterwards
impressed by ornamental rolls may be employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Weston in the Great Seal Patent Office on the
24th March 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WEBTON, of Birmingham, in the County of Warwick, Tubo, Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Weston, Her special licence, that I; the said Thomas
Weston, my executors, administrators, and assigns, or such others as I, the
said Thomas Weston, 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 "AN IMPROVE-
MENT OR IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL METALLIC TUBES,"
upon the condition (amongst others) that I, the said Thomas Weston, my

page_text: 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 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 Thomas Weston, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
My Invention consists of the improvement or improvements herein-after
described in the manufacture of ornamental metallic tubes, whereby economy
and simplicity of manufacture combined with strength and durability in the
tubes produced are secured. In the ordinary manufacture of ornamental
metallic tubes a solid brass or other tube of the required thickness is passed
through ornamental rolls, and its surface, ornamented by the pressure of the
said rolls. Or a thin ornamental tube made in one piece or in several pieces
produced by rolling or otherwise is secured by soldering, or brazing, or by
collars to a tubular foundation of iron..
In manufacturing ornamental metallic tubes according to my Invention,
I proceed as follows:-I take a tube or foundation of wrought iron of the
required strength, and I take another tube of thin brass and by a drawing
process, conducted in the ordinary manner, I coat or cover the said tube or
foundation of iron with the said thin tube of brass. The compound tube
thus produced is similar to the tubes known in commerce as cased tubes.
I take this compound tube and place in its interior a steel mandril and pass
the said compound tube supported upon its mandril through ornamental rolls
of the ordinary kind, the acting surfaces of the said rolls, baving engraved
upon them the pattern or ornament it is wished to impress upon the tube.
By the pressure to which the compound tube is subjected in its passage
through the rolls the outer brass case or tube of the said compound tube
is impressed with the pattern or ornament upon the said rolls, and an ornamental
tube thereby produced. On being removed from the mandril the ornamental
tube resembles a solid brass ornamental tube, whereas it is a compound
tube, the interior being of iron and the exterior of brass. Instead of drawing
the thin brass tube upon a tabe or foundation of iron, and supporting the com-
pound tube during its passage through the rolls by a steel mandril the
thin brass tube may be drawn upon a steel tube or a solid core or founda-
tion, and the said tube and steel foundation passed through the ornamental

page_text: rolls. In this case the steel tube or solid core forms the permanent foundation of
the ornamented tube. Instead of employing a thin tube of brass as described
for covering the tube or foundation of iron or foundation of steel, a thin
tube of copper or other metal or alloy capable of being drawn upon a
metallic foundation and afterwards impressed by ornamental rolls may be
employed.
Having now described the nature of my Invention and the manner in
which the same is to be performed, I wish it to be understood that I do not limit
myself to the precise details herein described as the same may be varied without
departing from the nature of my Invention; but I claim as my Invention the
improvement or improvements in the manufacture of ornamental metallic tubes
berein-before described, that is to say, making ornamental tubes by coating or
covering a tube or foundation of iron, or a tubular or solid core or foundation
of steel, by a drawing process with a thin metallic tube, and passing the
compound tube or tube and solid steel core or foundation through ornamental
rolls, whereby the outer thin tube or case is ornamented or impressed with
the pattern or ornament upon said rolls, substantially as herein-before
described.
In witness whereof, I, the said Thomas Weston, have hereunto set my
hand and seal, this Twenty-third day of Marcb, in the year of our
Lord One thousand eight bundred and sixty-eight.
Witness,
GEORGE SHAW.
THOMAS WESTON. (L.B.)
