IMPROVEMENTS IN THE MANUFACTURE OF METAL TUBES
Year: 1884

page_text: I, ELI DEELEY of Walsall in the County of Stafford Mill Roller, do hereby
declare the nature of my said invention for IMPROVEMENTS IN THE MANUFACTURE
OF METAL TUBES, to be as follows:-
This Invention refers to the manufacture of metal tubes of various peculiar
sections such as square oval half round and corrugated and it consists in rolling
such sections from the strip at one. heat.
For squares I take the heated strip either in straight length or coiled and pass it
through rolls of an oval or diamond section and then repass it edgeways through.
rolls of a square section. For oval sections I turn up the end of the strip and
insert it into the mouth of a funnel shaped die through which it is drawn and
passes into rolls of an oval section by which it is closed and completed.
For half round tubes I first roll the strip into a round tube and then by means
of a second pair of suitably shaped rolls I crush down a flat side to form the
section required. For corrugated sections when they are required to be welded
I first form a round welded tube and then pass it through shaping rolls to corrugate
it but when a close jointed tube only is required I pass the strip through a pair of
rolls which turn it up and partly form it and then through a second pair by which
it is closed and completed.
Other sections may be similarly formed. An important point of my Invention
is that I take a coil of strip heat it and whilst still hot pass the end into the rolls
and unwind the coil like a ribbon in its passage through the rolls by which the full
heat is maintained to the end of the strip.

page_text: I, ELI DEELEY of Walsall in the County of Stafford Mill Roller do hereby
declare the nature of my said invention for IMPROVEMENTS IN THE MANUFACTURE
OF METAL TUBES, 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 :-
This Invention refers to the manufacture of metal tubes of various peculiar
sections such as square oval half round and corrugated and it consists in rolling
such sections from the strip at one heat.
For squares and similar sections I take the heated strip either in straight lengths
or coiled and pass it through rolls of an oval or diamond section and then repass it
edgeways, through rolls of a square section.
For oval sections I turn up the end of the strip and insert it into the mouth of a
funnel shaped die through which it is drawn and whence it passes into rolls of an
oval section by which it is closed and completed. For half round tubes I first roll
the strip into a round tube and then by means of a second pair of suitably shaped
rolls I crush down a flat side to form the section required. For corrugated sections
when they are required to be welded I first form a round welded tube and then
pass it through shaping rolls to corrugate it, But where a close jointed tube only
is required I pass the strip through a pair of rolls which turn it up and partly form
it and then through a second pair by which it is closed and completed, other
sections may be similarly formed.
Referring to the drawings Fig 1. is a section into which the strip is first formed
in making the square tubes Fig 2. Fig 3..shews an oval section formed as described.
Fig 4 shews the section into which the strip is first formed in making the half
round tubes Fig 5. Fig 6 shews the section into which the strip is formed in
making the welded corrugated tube Fig 7. and Fig 8 shews another section for
a fender bead made in a similar way to the oval Fig 3 but with an open joint.
An important point in my invention is that I can take a coil of strip, heat it
and whilst still hot pass the end into the rolls and unwind the coil like a ribbon
on its passage through the rolls thus producing great lengths of tube of any section
such as round, oval, square, half round and corrugated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The manufacture of tubes of any required section from a coil of strip heated and
rolled into tubes at one heat.
