IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL METALLIC TUBING
Year: 1874

page_text: LETTERS PATENT to James Atkins, of the Firm of Robert Walter
Winfield and Company, of Birmingham, in the County of Warwick,
Merchants and Manufacturers, for the Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF ORNAMENTAL METALLIC TUBING."
Sealed the 19th June 1874, and dated the 16th January 1874.
PROVISIONAL SPECIFICATION left by the said James Atkins at the
Office of the Commissioners of Patents, with his Petition, on the
16th January 1874.
I, JAMES ATKINS, of the Firm of Robert Walter Winfield and Com-
pany, of Birmingham, in the County of Warwick, Merchants and
Manufacturers, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTAL METALLIC TUBING," to be
as follows:-
-
In the ordinary method of manufacturing ornamental metallic tubing
a plain tube is manufactured, and the said plain tube is passed through
a series of four or other number of steel rolls, the peripheries of which
have engraved or sunk on them the design or pattern to be impressed

page_text: upon the tube, the peripheries of the rolls being so presented to each
other that those portions of the said peripheries opposed to each other
constitute virtually a moveable or travelling draw plate through which
the tube passes.
By this method of manufacture the character of the design or pattern
which can be thus impressed upon the tube is much restricted, and the
designs or patterns cannot be made in high or bold relief.
In manufacturing ornamental metallic tubing according to my Inven-
tion I take the strip of sheet metal of which the tubing is to be made,
and while in a flat or nearly flat state I operate upon it by means of a
stamp and a pair of dies, or a die and force, which dies or die and force
are provided with the ornamental design or pattern to be impressed upon
the tubing.
By working the moveable die or force in the stamp in the ordinary
way, and advancing the sheet metal strip on the lower die after each
blow a series of impressions is produced on the said strip. These
impressions may either consist of detached or separated ornamental
patterns, or the said impressions may be made to form a continuous or
running pattern on the strip.
Ono or other number of rows of detached designs or running patterns
may be made on the strip, and where required the plain portions of the
strip may be pierced with ornamental piercings in the ordinary way.
The flat or nearly flat strip of metal thus ornamented or ornamented
and pierced is next bent up into a skelp or open jointed tube, and its
edges are afterwards connected by brazing.
By means of a plug over which the tubing is next drawn a cylindrical
or nearly cylindrical general figure is given to the tubing.
Instead of cylindrical ornamental tubing ornamental tubing hexagonal
or of other figure in cross section may be made according to my Inven-
tion.
Where the tubing is not cylindrical the plug on which it is drawn has
a figure corresponding to that of the interior of the tubing.
Where it is necessary to apply pressure externally to give the required
figure to the tube the said pressure may be applied to the plain or
unornamental parts of the tubing.

page_text: Tubing made according to my Invention may be finished by burnishing
the projecting parts of the pattern or ornament, or by any of the
ordinary methods of finishing metallic articles.
ied by the said James ALKIDS in the Great Seal Patent Umce
on the 14th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
ATKINS, of the Firm of Robert Waiter Winfield and Company, of
Birmingham, in the County of Warwick, Merchants and Manufacturers,
'send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of January, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said James Atkins, Her
special license that I, the said James Atkins, my executors, admi-
nistrators, and assigns, or such others as I, the said James Atkins,
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 THE MANUFACTURE OF ORNAMENTAL METALLIC TUBING," upon
the condition (amongst others) that I, the said James Atkins, 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 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 imme-
diately after the date of the said Letters Patent.

page_text: performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
In the ordinary method of manufacturing ornamental metallic tubing
a plain tube is manufactured, and the said plain tube is passed through
a series of four or other number of steel rolls, the peripheries of which
have engraved or sunk on them the design or pattern to be impressed
upon the tube, the peripheries of the rolls being so presented to each
other that those portions of the said peripheries opposed to each other
constitute virtually a moveable or travelling draw plate through which
the tube passes.
By this method of manufacture the character of the design or pattern
which can be thus impressed upon the tube is much restricted, and the
designs or patterns cannot be made in high or bold relief.
In manufacturing ornamental metallic tubing according to my Inven-
tion I take the strip of sheet metal of which the tubing is to be made, 1
and while in a flat or nearly flat state I operate upon it by means of a
stamp or press and a pair of dies, or a die and force, which dies or die
and force are provided with the ornamental design or pattern to be
impressed upon the tubing.
By working the moveable die or force in the stamp or press in the 2
ordinary way, and advancing the sheet metal strip on the lower die after
each blow a series of impressions is produced on the said strip.
One or other number of rows of detached designs or running patterns
may be made on the strip, and where required the plain portions of the
strip may be pierced with ornamental piercings in the ordinary way.
The flat or nearly flat strip of metal thus ornamented or ornamented
and pierced is next bent up into a skelp or open jointed tube, and its
edges are afterwards connected by brazing.
By means of a plug over which the tubing is next drawn a cylindrical
or nearly cylindrical general figure is given to the tubing.
Figure 1 represents in plan and edge view, a strip of sheet metal
which has been ornamented while in the flat by the operation of a pair
of ornamented dies or by a die and force worked in a stamp or press as
before described, and Figure 2 represents in perspective and end elevation
a piece of tubing made by bending the flat ornamented strip, Figure 1,
6

page_text: into an open jointed tube, brazing its edges, and finally drawing the said
tube to perfect its form.
By an examination of the edge view of Figure 1. it will be seen that
the ornamental pattern impressed upon the flat strip has considerable
relief.
Figure 3 represents an ornamented strip impressed as before described,
and Figure 4 a piece of tubing made therefrom having a different orua-
mental pattern from that on the strip and tubing, Figures 1 and 2, the
impressed pattern on the said strip, Figure 3, consisting of detached or
separated ornaments, while that on the strip Figure 1 consists of a
running or continuous pattern.
Figure 5 represents another strip of sheet metal ornamented according
to my Invention, as before described, and Figure 6 a piece of tubing
made therefrom.
In this ornamented strip the impressions upon it consist of a con-
tinuous or running pattern, the said pattern being made in less relief
than in the strips before referred to.
Figure 7 represents an ornamented strip, and Figure 8 a piece of
tubing made therefrom, having the same pattern upon it as the strip and
tubing, Figures 5 and 6, excepting that the dividing ribs or bands of the
pattern are situated at right angles to the axis of the tubing instead of
inclined thereto.
Instead of cylindrical ornamental tubing as represented, ornamental
tubing, hexagonal, or of other figure in cross section may be made
according to my Invention.
Where the tubing is not cylindrical the plug on which it is drawn has
a figure corresponding to that of the interior of the tubing.
Where it is necessary to apply pressure externally to give the required
figure to the tube the said pressure may be applied to the plain or
ornamental parts of the tubing.
Ornamental tubing made according to my Invention may be used in
its unbrazed state in all cases where open jointed tubing is or may be
employed.
Tubing made according to my Invention may be finished by burnish-
ing the projecting parts of the pattern or ornament, or by any of the
ordinary methods of finishing metallic articles.

page_text: 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 improvements in the manufacture of
ornamental metallic tubing herein-before described and illustrated in the
accompanying Drawings, that is to say, making ornamental tubing by
taking strips of sheet metal, and while in the flat or nearly flat state
impressing upon them by means of ornamented dies or a die and force
worked in a stamp or press the pattern or design with which the tubing
is to be ornamented, the flat or nearly flat ornamented strip being made
into open jointed tubing or brazed tubing, substantially in the manner
herein described.
In witness whereof, I, the said James Atkins, have hereunto set
my hand and seal, this Ninth day of July, in the year of our Lord 1
One thousand eight hundred and seventy-four.
Witness,
CHARLES WALKER TORR.
