Complete Specification Left, 8th Aug., 1894-Accepted, 8th Sept., 1204
PROVISIONAL SPECIFICATION.
Improvements in the Securing of Flanges and other Fittings upon
Metal Pipes and Bodies.
We HENRY STOREY and WILLIAM EDWARD STOREY of the Firm of Isaac
Storey and Sons, of Little Peter Street, Knott Mill, Manchester, in the County of
Lancaster, Brass Founders, do hereby declare the nature of this invention to be
as follows:-
―
Our invention relates principally to the securing of flanges upon pipes or tubes
by brazing or soldering processes and whilst being particularly applicable in the
cases of solid drawn copper tubes may be used in the manufacture of flanged or
socketed pipes or tubes of other metal or otherwise produced and in the attachment
of flanges or rings upon cylinders and other bodies.
In ordinary practice a flange is secured upon the end of a tube by sweating in the
brazing or soldering alloy.
In our invention we turn or form an annular channel inside the bore of the flange
or part to be attached and we cut or form one or two or more ducts through which
melted spelter or suitable alloy can be run into the said channel. The parts are
heated and prepared with flux as usual and the melted alloy is run into the said
channel so as to completely fill the same and also to run into the narrower spaces
between the two bodies being sweated into such spaces if necessary.
The intention is that the alloy used shall combine with the surface of the tube
and in most or in all cases with both tube and flange or ring the result being the
formation of a strong key which secures a firmer connection and attachment of the
two parts.
If a firmer connection be considered to be desirable the tube may be grooved.
In some cases the formation of special ducts might not be necessary.

COMPLETE SPECIFICATION.
Improvements in the Securing of Flanges and other Fittings upon
Metal Pipes and Bodies.
We HENRY STOREY and WILLIAM EDWARD STOREY of the Firm of Isaac
Storey and Sons, of Little Peter Street, Knott Mill, Manchester, in the County of
Lancaster, Brass Founders, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying drawings :-
Our invention relates principally to the securing of flanges upon pipes or tubes
by brazing or soldering processes, and whilst being particularly applicable in the
cases of solid drawn copper tubes, may be used in the manufacture of flanged or
socketed pipes or tubes of other metal, or otherwise produced, and in the attachment
of flanges or rings upon cylinders and other bodies.
In ordinary practice a flange is secured upon the end of a tube by sweating in the
brazing or soldering alloy.

page_text: In our invention we turn or form an annular or other channel inside the bore of
the flange or part to be attached, and we cut or form one, two or more ducts,
through which melted spelter or suitable alloy can be run into the said channel.
The parts are heated and prepared with flux as usual, and the melted alloy is run
into the said channel so as to completely fill the same and also to run into the
narrower spaces between the two bodies, being sweated into such spaces if
necessary.
The intention is that the alloy used shall combine with the surface of the tube
and in most or in all cases with both tube and flange or ring, the result being the
formation of a strong key which secures a firmer connection and attachment of the
two parts.
If a firmer connection be considered to be desirable the tube also may be grooved
In some cases the formation of special ducts might not be necessary.
In the accompanying drawings.
Fig. 1 represents a section of a pipe with flange prepared and attached according
to our improved method.
Fig. 2 is a plan of Fig. 1.
In the said figs., a is the copper tube and 6 the flange secured to the tube by the
spelter or alloy c.
The bore of the flange b, is turned or formed with a channel d, and we provide a
suitable number of ducts or ports e, extending to the back of the flange and
communicating with the channel d.
In securing the flange to the pipe the flange is slipped over the end of the
pipe a and the parts are heated and fluxed in the usual manner.
Melted spelter,
solder or other suitable alloy is then run through the ducts e into the channel d,
which it fills, and within which it sets. Any narrower spaces between the two
bodies are at the same time filled by the spelter or alloy which might if necessary
be sweated into such smaller spaces. In setting, the spelter or alloy combines with
the surfaces of the flange and tube with the result that when cold, a strong key or
connection between pipe and flange is formed. The end of the tube may be
expanded in the flange as shown in Fig. 1, and the inner end of the flange boss may
be cupped so as to retain a ring of spelter as clearly shown in Fig. 1.
In some case where a firmer connection between tube and flange is desired, we
might groove or channel the tube as well as the flange.
This method is illustrated by Fig. 3 which shows a section of pipe and flange on
a reduced scale.
In this case the spelter or alloy fills and sets within both channels, and constitutes
a strong key embedded in both pipe and flange, thus rendering the connection
additionally secure.
The provision of special ducts e to admit the melted spelter or alloy is not an
absolute necessity, as we might make the inner part of the bore of the flange large
enough to present an annular space surrounding the tube, through which the spelter
could flow to the channel or channels.
We do not confine the application of our invention to the securing of flanges
upon tubes as our improvements could be utilised in the securing of flanges, rings
or parts upon cylinders and other bodies.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The improved method of securing flanges, rings and parts upon pipes and other
bodies, substantially as described in the foregoing Specification and as illustrated in
the drawings.
2. As means for securing flanges, rings or parts to pipes and other bodies,
forming the bore of the flange or ring with a channel, and if thought desirable also
channelling the pipe or part carrying the flange or ring, into which channel or
channels melted spelter, solder or alloy is run through ducts or spaces so as to

as described and as illustrated.
