Manufacturer for an Invention of "AN IMPROVEMENT IN OR RELATING TO
METALLIC TUBES AND IN THE MANUFACTURE OF THE SAME "
PROVISIONAL SPECIFICATION left by the said Richard Heeley at the Office
of the Commissioners of Patents on the 27th June 1883.
RICHARD HEELEY, of Shirley, in the County of Warwick, Manufacturer. "AN
IMPROVEMENT IN OR RELATING TO METALLIC TUBES AND IN THE MANUFACTURE
OF THE SAME
"
This Invention has reference to an improvement in or relating to metallic tubes
and to the manufacture thereof; and a principal object of the Invention is to
produce tubes of metal or alloy without necessitating the soldering or brazing of
the connected edges.
According to this Invention, the tubes are made of two pieces, one of which (in
the modification now being described) may be considerably more than one half of
the whole diameter of the tube, and the edges of this part are turned round and
flanged inwardly of the tube, the other piece completes the diameter of the tube and
its edges are turned and flanged outwardly. Both these pieces may be of any
desired length, width, or thickness, these depending principally upon the diameter
of the intended tube. In manufacturing the tube, the two pieces are sprung
together, or the smaller piece may be slid end wise into the larger piece in such a
way that its outer flanged edges slide along and clip the innner flanged edges of the
other part. When in position, the flanged edges of the two pieces are tightly
closed upon each other, and the formation of the tube completed, by the aid of
suitable tool or appliance.
any
By means of this improvement, not only is the soldering or brazing of the edges
avoided, but there is produced a cheaper and better article.

RICHARD HEELEY, of Shirley, in the County of Warwick, Manufacturer,
IMPROVEMENT IN OR RELATING TO METALLIC TUBES AND IN THE MANUFACTURE
OF THE SAME
"
This Invention has reference to an improvement in or relating to metallic tubes,
and to the manufacture thereof; and a principal object of the Invention is to
produce tubes of metal or alloy without necessitating the soldering or brazing of
the connected edges.
The accompanying drawings illustrate tubes made according to the present-
Invention and represent the improved tubes as made of two pieces 1, 2, (sec
Figs 1 and 2) the former of which (in the modification now being described) is
represented as made of considerably more than one half of the whole circumference
of the tube, and the edges of this part are turned round and flanged inwardly of
the tube as shown at 3, the other piece 2, completes the circumference of the tubo,
and its edgos 4, are turned and flanged outwardly. Both these pieces may be of
any desired length, width or thickness these depending principally upon the size or
diameter of the intended tube. In manufacturing the improved tubes, the two
pieces 1, 2, are sprung together, or the smaller piece 2, may be slid end wise into
the larger piece 1, in such a way (as shown in Fig 3) as that its outer flanged
edges 4, slide along and clip the inner flanged edges 3, of the part 1. When in
position the flanged edges of the two pieces 1, 2, are tightly closed upon each other,
and the formation of the tube completed, by the aid of any suitable tools or
appliance. Fig 4 represents a section of the completed tube. Fig 5 represents a
_section of a lined or cased tube.
By means of this improvement, not only is the soldering or brazing of the edges
avoided, but there is produced a cheaper and better article.
This Invention may be used in the manufacture of plain or ornamental cased or
other tubes used for bedsteads and general purposes, and in the manufacture of
tyres for wheels, and other parts of velocipedes, and other vehicles.
The improved tubes may be made in the manner herein before described of one
or more parts, the edges to be connected being formed to clip each other substantially
in the manner hereinbefore described.
Having thus particularly described and ascertained the nature and object of iny
said Invention and in what manner the saine is to be or may be performed or
carried into practical effect I would observe in conclusion that what I consider to
be novel and original and therefore claim as constituting the Invention secured
to me by the herein before in part recited Letters Patent, is:-
The manufacture of metallic tubes by forming them of one or more parts the
edges of which are formed to clip each other and which when clipped together
form a complete tube substantially as hereinbefore described with reference to the
accompanying drawings.
In Witness whereof, I, the said Richard Heeley, have hereunto set my hand
and seal, this 15th day of December in the year of our Lord One thousand eight
hundred and eighty three.
