I RICHARD HOBBS TAUNTON of Heneage Street Birmingham in the County of
Warwick Tube Manufacturer do hereby declare the nature of this Invention to be as
follows:
-
The said invention consists in constructing a flexible connection for joining or
uniting the ends of pipes or tubes for tubulous steam boilers and for other purposes
by making the bends or lateral connections and the ends of the pipes or tubes to be
secured to the said bends together with a flexible connecting ring substantially as
herein after described.
These improvements are particularly applicable to the joining or connecting together
of the ends of a series of parallel pipes or tubes but may also be applied to pipes or
tubes inclined to one another and to continuous pipes or tubes.
The ends of the two pipes or tubes to be joined or connected together are provided
with tubular heads near the open ends of which conical shoulders are made. The
ends of the connecting bend are bevilled or conical the conical ends joining the
other parts by shoulders or stops. Between the heads on the ends of the pipes or
tubes and the ends of the connecting bend flexible metallic rings are fitted. The
said flexible metallic rings are conical. The narrow end of the conical ring is
provided with a neck also conical the outer end of the said ring and the outer
end of the neck being of greatest diameter.
fits closely in the opening in the end of the
shoulder at the said end and the conical ends
themselves in the necks of the flexible rings.
The wide end of the conical ring
pipe or tube and upon the conical
of the connecting bend fit or seat
By means of lugs on each bend and

page_text: pipe or tube head and screw bolts and nuts the said heads and bend are secured
together. After the parts of the junction have been properly fastened together the
ends of the bend are screwed up to the ends of the pipes or tubes with sufficient force
to put the flexible rings under tension and thereby cause the outer edges of the rings
to be expanded into their seats at the ends of the pipes or tubes and the necks of the
said rings to be tightened upon the conical ends of the bend. A very tight and secure
joint is thereby formed. The flexibility of the connecting rings permits the bends
and pipes or tubes to have all the movements relativo to one another necessary to
compensate for the expansion and contraction of the said bends and pipes or tubes.
The said invention is applicable to the joining or connecting of pipes or tubes for
heaters condensers tubulous steam boilers and other tubular structures.

I RICHARD HOBBS TAUNTON of Heneage Street, Birmingham in the County of
Warwick, Tube Manufacturer do hereby declare the nature of the said Invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The said invention consists in constructing a flexible connection for joining or
uniting the ends of pipes or tubes: or tubulous steam boilers and for other purposes
by making the bends or lateral connections and the ends of the pipes or tubes to be
secured to the said bends together with a flexible connecting ring substantially as
hereinafter described.
These improvements are particularly applicable to the joining or connecting together
of the ends of a series of parallel pipes or tubes but may also be applied to pipes or
tubes inclined to one another and to continuous pipes or tubes.
The ends of the two pipes or tubes to be joined or connected together are provided
with tubular heads near the open ends of which conical shoulders are made. The
ends of the connecting bend are bevilled or conical the conical ends joining the other
parts by shoulders or stops. Between the heads on the ends of the pipes or tubes and
the ends of the connecting bend flexible metallic rings are fitted. The said flexible
metallic rings are conical. The narrow end of the conical ring is provided with a
neck also conical, the outer end of the said ring and the outer end of the neck being
of greatest diameter. The wide end of the conical ring fits closely in the opening in
the end of the pipe or tube and upon the conical shoulder at the said end and the
conical ends of the connecting bend fit or seat themselves in the necks of the flexible
rings. By means of lugs on each bend and pipe or tube head and screw bolts and
nuts the said heads and bend are secured together. After the parts of the junction
have been properly fastened together, the ends of the bend are screwed up to the ends
of the pipes or tubes with sufficient force to put the flexible rings under tension and
thereby cause the outer edges of the rings to be expanded into their seats at the ends
of the pipes or tubes and the necks of the said rings to be tightened upon the conical
ends of the bends. A very tight and secure joint is thereby formed.
The flexibility of the connecting rings permits the bends and pipes or tubes to have
all the movements relative to one another necessary to compensate for the expansion
and contraction of the said bends and pipes or tubes.
Figure 1 of the accompanying Drawing represents two pipes or tubes of a tubulous
steam boiler joined or connected together according to this invention a portion of the
bend and one pipe or tube being represented in longitudinal section and the other
parts in elevation; Figure 2 represents an end view of a portion of the bend, looking
towards the end of the pipe; Figure 3 represents an end view of one of the pipes and
its head; Figure 4 represents an enlarged sectional view of the flexible ring and
adjoining parts and Figure 5 represents a modification of the connection.

page_text: The same letters of reference indicate the same parts in the several Figures of the
Drawing.
a, a are the two pipes or tubes to be connected together and b, b are the heads into
which the ends of the pipes are expanded or otherwise attached. The openings c, c in
the said heads are directly in front of the ends of the pipes and are provided with
conical shoulders d, d; e, e are metallic discs or rings constructed to fit closely in the
openings e and upon the shoulders d. The said rings e are conical in shape and
sufficiently thin to have the flexibility required for the purpose for which they are
used. The shape of the flexible rings e is best seen in the sectional view Figure 4; fis
the connecting bend the ends g, g of which are hevilled and fit into the necks e² of the
flexible rings e. Shoulders h, at the ends of the bend prevent their conical ends
being forced too far into the flexible rings by coming in contact with the necks e²
of the said rings; ii are lugs on each end of the bend and jjare lugs upon the
heads of the pipes. By means of the said lugs and the screw bolts k, k the bend
and heads of the pipes are held together.
After the parts of the junction have been properly arranged and fastened together
the ends of the bends gare screwed down with sufficient force to put the connecting
rings e under tension which causes their outer edges to be expanded into their seats
in the heads of the pipes and their inner edges or necks e² to be tightened upon the
tapering ends g of the bend, thus making very tight and secure joints. The flexibility
of the connecting rings e permits the bends and the pipes with their heads to have all
the movement relatively that is necessary to compensate for the varying effects of
expansion and contraction without opening the joints; further the end wise movement
of either or both of the two pipes united by a bend is compensated for by the lateral
movement of the bend and hence by the action of both of the connecting rings so that
dividing the effects of expansion and contraction between the flexible connecting
rings of two or more joints enables small rings to be used and compact joints to
be made.
Figure 5 represents a modified form of bend marked 1, the said bend / being in
all essential respects the same as that represented in Figure 1 but constructed for
connecting the adjacent lengths of an extended line of pipes. Other modifications
may be used such as seating the flexible rings in the bends or in the ends of the
pipes and using other means of connecting the ends of the pipes to the bends but
the construction of the parts described and illustrated shows the essence of this
invention.
The said invention is applicable to the joining or connecting of pipes or tubes for
heaters condensers, tubulous steam boilers and other tubular structures and pipes or
tubes for various purposes.
Having now particularly described and ascertained the nature of this invention and
the manner in which the same is to be performed I declare that 1 claim as the said
Invention:-
Joining or connecting pipes or tubes for tubulous steam boilers and for other
purposes by means of a flexible ring having its outer edge expanded into a seat for
one of the connecting parts to seat itself upon and its inner edge tightened around the
other connecting part, the several parts being constructed and combined and acting
substantially as herein before described and illustrated in the accompanying Drawing.
