IMPROVEMENTS IN THE MANUFACTURE AND COATING OR CASING OF METALLIC TUBES AND RODS
Year: 1869

page_text: LETTERS PATENT to Thomas Weston and Hugh Weston, both of
Birmingham, in the County of Warwick, Tube Manufacturers, for
the Invention of "IMPROVEMENTS IN THE MANUFACTURE AND COATING
OR CASING OF METALLIC TUBES AND RODS."
Sealed the 19th April 1870, and dated the 17th November 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Weston and
Hugh Weston at the Office of the Commissioners of Patents, with
their Petition, on the 17th November 1869.
We, THOMAS WESTON and HUGH WESTON, both of Birmingham, in
the County of Warwick, Tube Manufacturers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE AND
COATING OR CASING OF METALLIC TUBES AND RODS," to be as follows, that is
to say :-
Our Invention relates to improvements in the manufacture of lock-
jointed metallic tubes and solid cased rods or rodding, whereby economy
and simplicity of production with strength and durability of the articles
produced are obtained.

page_text: In making lock-jointed tubes, as for instance, the description com-
monly known as "cased" tubes, we form the inner shell or tube in the
ordinary manner with an open joint, as shewn in section Figure 1.
We form the skeleton or casing tube, Figure 2, with the edges turned
inwards to form lips or grooves so as to pass over the inner shell or tube,
Fig. 1, as shewn in Figure 3; we then form a lock strip or clip (a),
Fig. 3, for locking or securing the edges of the metal or case; and the
tube thus produced is then passed through finishing tools with a suitable
plug or mandril in the tube, when it will present the form in section of
Figure 4. Or the open joint of the inner shell may be made of suitable
width to admit of the lock joint being formed within such width, or the
inner shell may be recessed or grooved in its thickness on the inner side
to allow the lock joint to lie within such depth.
In making tubes which are not cased we proceed in every respect as
described omitting the use of the inner shell, Fig. 1.
In making solid cased rods or rodding according to our Invention we
take a strip of metal and pass it through tools to produce the form
shewn in Fig. 5, having the edges of the metal turned inwards, wo
then pass the casing or tube over a solid rod, Fig. 6, furnished with
a longitudinal groove to receive the turned in edges of the outer casing
or tube and form the lock or joint, the rod is then finished by being
passed through finishing tools.
By the manufacture of metallic tubes and solid cased rods or rodding,
as described, the use of solder is dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Weston and Hugh Weston in the Great
Seal Patent Office on the 17th May 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
WESTON and HUGH WESTON, both of Birmingham, in the County of
Warwick, Tube Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of November, in the
year of our Lord One thousand eight hundred and sixty-nine, in the

page_text: thirty-third year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Thomas Weston and Hugh
Weston, Her special licenco that we, the said Thomas Weston and
Hugh Weston, our executors, administrators, and assigns, or such others
as we, the said Thomas Weston and Hugh Weston, our 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 MANUFACTMRE AND COATING OR CASING OF METALLIC TUBES AND RODS,'
upon the condition (amongst others) that we, the said Thomas Weston
and Hugh Weston, our executors or administrators, by an instrument
in writing under our, 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 we, the said Thomas Weston and Hugh
Weston, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had
to the Drawings hereunto annexed, and to the letters and figures
marked thereon, that is to say:-
Our Invention relates to improvements in the manufacture of lock-
jointed metallic tubes and solid cased rods or rodding, whereby economy
and simplicity in the manufacture with strength and durability of the
articles produced are obtained, the use of solder in the formation of the
said metallic tubes and solid cased rods or rodding according to our
Invention being dispensed with.
The precise nature of our improvements will be better described and
ascertained by referring to the accompanying Drawings.
In making lock-jointed tubes, as for instance, the description com-
monly known as "cased tubes," we form an inner shell or tube, Figure 1,
in the ordinary manner with an open joint (a), and we form the skeleton
or casing tube, Figure 2, with the edges turned inwards so as to produce
the lips or grooves (6), the casing tube, Figure 2, being passed over the

page_text: inner shell or tube, Figure 1, as shewn in Figure 3, so that the lips or
grooved edges (b) pass within the open joint (a) of the inner shell or tube;
we then form a lock strip or clip, Figure 4, for the purpose of locking or
securing the grooved edges (6) of the outer tube; the tube thus produced
is then passed through finishing tools with a suitable plug or mandril
in the tube, when it will present the form in section of Figure 5. Or as
shewn in Figure 6 the open joint (a) of the inner shell or tube may be
made of suitable width to admit of the lock joint described within such
width, by which means the inner surface of the tube will be regular and
free from projecting parts; or again, the inner shell may be recessed, 1
indented, or grooved in its thickness upon the inside, as shewn in
Figures 7 and 8, or upon the outside, as represented in Figures 9, 10,
and 11, so as to allow the lock joint to lie within the depth of such
recess, indent, or groove. The joint shewn in Figure 10 we sometimes
prefer to employ instead of that before specified, in which case the lock 1
strip or clip Figure 4, will not be required.
It will be seen that in forming the lock in a recess or indent upon the
outside of the inner shell, as shewn in Figures 9, 10, and 11, the open
joint (a), Figure 1, will be unnecessary.
In making tubes which are not cased, we proceed in every respect as 2
described, omitting the use of the inner shell Figure 1. Figure 12 shew's
in section a tube not cased, and secured by means of our improved
lock joint.
In making solid cased rods or rodding according to our Invention, we
take a strip of metal and pass it through tools to produce the form shewn 2
in Figure 13, having the edges of the metal turned inwards, as at (c),
we then pass the casing or tube over a solid metallic rod, Figure 14,
furnished with a longitudinal groove (d) to receive the turned in edges (c)
of the outer casing or tube, and thus form the lock or joint, the rod is
then finished by being passed through finishing tools, and presents the 3
form of Figure 15.
We have described and shewn our Invention as applicable for the
manufacture of tubes and rods of a circular form; but we purpose
applying our improvements to tubes and rods of any other suitable
outline or shape in section.
Having thus described the object and nature of our said Invention,
and the manner in which the same is to be carried into effect, we claim,
3

page_text: without limiting ourselves to these precise details, the improvements
in the manufacture and coating or casing of metallic tubes and rods,
substantially in manner as herein more fully set forth and specified.
In witness whereof, we, the said Thomas Weston and Hugh
Weston, have hereunto set our hands and seals, this Twenty-
seventh day of April, in the year of our Lord One thousand
eight hundred and seventy.
