WILLIAM HENRY BECK of 139 Cannon Street, in the City of London, Consulting
Engineer and Patent Agent "A NEW OR IMPROVED UNION JOINT OR COUPLING

The invention relates to a new or improved union or coupling with an elastic
joint for connecting together, end to end pipes and tubes in general. The arrange-
ment may be called "variable
pressure union
because it is possible to effect the
connection of the pipes or tubes more or less firmly while preserving elasticity and
absolute tightness to the joint whatever the internal pressure may be. One of the
pipes or tubes to be joined is cylindrical in all its parts with one end swelled out
or enlarged and hollowed out or recessed for the reception of a washer of india
rubber or other suitable elastic and compressible material.
On the end of this pipe is fitted a ring which covers and stops against the
aforesaid enlargement. It is screwed externally at its front part
The other pipe or tube is also cylindrical except at the shoulder at its end which
is of an elliptic or oval form.
Another ring which is internally screwed takes on to the first mentioned ring, the
internal thread of the first taking into the external thread of the latter. It is
formed with an oval or elliptic opening corresponding to the oval or elliptic form

page_text: of the shoulder of the second pipe so that the said shoulder enters and passes
easily through the opening in the ring.
The elliptic or oval opening in the ring is followed by a cylindrical part which
is itself followed by the internally screwed part above mentioned. In the
cylindrical part are left two stops diametrically opposite to each other.
Putting the parts of the union or coupling together. Having put in place the
packing or elastic washer on the end of the first mentioned pipe the first mentioned
ring is threaded thereon and the second ring is screwed on to the said first
mentioned ring. Then the end of the second mentioned pipe is passed through the
opening in the second ring care being taken to make the oval or elliptic shoulder
on the pipe coincide with the oval or elliptic opening of the ring. Having passed
the shoulder of the pipe through the opening of the ring it is only necessary.to
turn the second ring about half a revolution until the stops prevent further
movement.
The union is then made. By screwing the second ring more or less upon the
first ring the indiarubber washer is squeezed with greater or lesser force that is to
say with a pressure which may be varied at pleasure according to the pressure
which the joint is intended to resist and to which the liquids, gases, fluids or
vapours may be subjected that the pipes so joined are intended to conduct.
The component parts may be varied as to forms materials and dimensions, and
the new or improved union or coupling may also be applied to connect together all
kinds of pipes tubes or conduits in which liquids fluids, gases, vapours and so forth
circulate.

WILLIAM HENRY BECK of 139 Cannon Street, in the City of London, Consulting
Engineer and Patent Agent "A NEW OR IMPROVED UNION-JOINT OR COUPLING
FOR PIPES AND TUBES [Communicated to him from abroad by Jules Louis
Bernardin Bodel, Machinist, and Joseph Laurent François Brauer, herbalist both
chez Messieurs Blétry frères, of N° 2 Boulevard de Strasbourg, Paris, in the
Republic of France.]
The invention relates to a new or improved Union or coupling with an elastic
joint for connecting together end to end-pipes and tubes in general. The arrange-
ment may be called a "variable pressure union" because it is possible to effect the
connection of the pipes or tubes more or less firmly while preserving elasticity and
absolute tightness to the joint whatever the internal pressure may be.
The annexed drawing represents an example of the new or improved union or
coupling.
Fig. 1 represents a longitudinal section figs. 2 and 3 external views of the end
of one of the pipes or tubes to be joined fig. 4, view of the end of the other pipe
or tube. fig 5, represents a section of one of the tightening rings, fig. 6. is an end
view of the said ring and fig. 7 an external elevation of the second tightening ring
a and b represent the pipes or tubes to be joined; the pipe or tube a is cylindrical
in all its parts with one end swelled out or enlarged at c; to this end is applied a
washer of indiarubber or other suitable elastic and compressible material. The
end c of the pipe or tube may be hollowed out on its end face if preferred for the
reception of the said elastic washer r.
On the end of the pipe or tube a, is fitted a ring d which covers and stops against
the aforesaid enlargement c. It is screwed externally at its front part.
The other pipe or tube b is also cylindrical except at the shoulder ƒ at its end
which is of an elliptic or oval form.
Another ring g which is internally screwed takes on to the ring d, the internal
screw thread of the first taking into the external screw thread of the latter. It is
formed at its other end with an oval or elliptic opening h corresponding to the
oval or elliptic form of the shoulder f of the pipe or tube b so that the said
shoulder can easily enter and pass into the opening h.
The elliptic or oval opening. h in the ring is followed by a cylindrical part k
which is itself followed by the internally screwed part above mentioned. In the
cylindrical part k are left two hollowed stops m m³ diametrically opposite to each
other and corresponding to the extremities of the greater diameter of the ellipse ƒ
of the pipe or tube b
PUTTING THE PARTS OF THE UNION OR COUPLING TOGETHER.
Having put in place the packing or elastic washer on the end of the pipe or
tube a the ring & is threaded thereon and the second ring g is screwed on to it.
Then the end of the pipe or tube b is passed through the opening of the ring g
care being taken to make the oval or elliptic shoulder f coincide with the oval or
elliptic opening h of the ring 9. Having passed the shoulder f through the
opening of the ring so as to clear the same it is only necessary to turn the pipe
or tube b or the ring g about a quarter of a revolution until the hollowed
stops m m¹ prevent further movement.
.

page_text: The union is then effected and by screwing the ring 9 more or less upon the
ng d the india-rubber washer may be afterwards squeezed with greater or
sser force according to the pressure which the joint is intended to resist, and to
hich are subjected the liquids gases fluids or vapours that the pipes or tubes so
ined are intended to conduct.
Having now described the nature of the said invention, and the manner in
hich the same is to or may be carried into effect, I would have it understood that
e forms, materials, and dimensions, of the parts constituting the new or improved
ion or coupling, with elastic joint and variable pressure, may be varied without
parting from the nature of the invention; that the said new or improved union
int or coupling is applicable to all kinds of pipes, tubes, and conduits, for liquids,
aids, gases, and vapours, and that what I claim as the invention to be secured by
e within in part recited letters patent is, the union with elastic joint, essentially
aracterized by the elliptic or oval forms of the jointing parts, the novel features
the said Union joint or coupling consisting
rstly In forming one of the pipes or tubes a with an enlarged end c, to serve as
a stop to a screwed ring d, fitted on the preceding cylindrical part of the said
pipe and on the said enlargement c, substantially as hereinbefore described and
illustrated in the drawing.
condly. In letting into a recess of the pipe a a washer of indiarubber, or other
suitable clastic and compressible material, or simply applying such washer on
the end of the said pipe, as herein before described.
irdly. In screwing on to the ring d another ring g screwed internally for that
purpose and formed at the end opposite to the screwed part into an opening h
of elliptic or oval shape with an intermediate cylindrical hollow in which
are formed the hollow stops m m¹ diametrically opposite to each other,
substantially as hereinbefore described and illustrated in the drawing.
urthly. In terminating the second pipe or tube b by a shoulder f of elliptic or
oval form capable of entering easily into the elliptic or oval opening h of the
second ring g, and of being secured in the said ring by turning it a quarter of
a revolution in the cylindrical hollow, as hereinbefore described and
illustrated in the drawing.
fthly. In producing at pleasure the required pressure on the joint washer by
screwing up more or less tightly the two rings d and g one on the other as
hereinbefore described.
In witness whereof I the said William Henry Beck have hereunto set my
hand and seal this twenty fourth day of January in the Year of Our Lord
one thousand eight hundred and eighty three.
