FICATION.
Improvements in or connected with Joints or Connections for Pipes
or Tubes.
We, ANDREW EADIE, and JOHN TANNAHILL, of the Clydesdale Tube Works,
Rutherglen, in the County of Lanark, North Britain, Tube Manufacturers, do
hereby declare the nature of this invention to be as follows, that is to say :—
Our said invention has for its object to apply to pipes or tubes an improved
device for jointing or connecting lengths of them together, and which when
required may be arranged to allow of two lengths being connected with a slight
inclination to each other.
In carrying out our invention one tube end at a joint is made with an enlarge-
ment which is in the form of a spherical faucet and is concave or is largest at its
extreme edge. The other tube end is also made with an enlargement but the
extreme end is contracted beyond the enlargement so as to form a convex spherical
spigot adapted to enter the spherical fancet of the other tube end. Flange rings
are put on each tube end and are connected by bolts, which may be screwed up
more at one side than at the other when the two tube lengths are to be at a slight
angle to each other. A packing of suitable compressible material may be inserted
between the joint surfaces of the faucet and spigot. The enlargements may be
formed on the tube ends by means of suitably shaped expanding tools, or in any
other convenient way.
Dated this Sixth day of September 1890.

COMPLETE SPECIFICATION.
Improvements in or connected with Joints or Connections for Pipes
or Tubes.
We, ANDREW EADIE and JOHN TANNAHILL of the Clydesdale Tube Works,
Rutherglen, in the County of Lanark, North Britain, Tube Manufacturers, 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, that is to say :-
Our said invention has for its object to apply to pipes or tubes an improved
device for jointing or connecting lengths of them together, and which when
required may be arranged to allow of two lengths being connected with a slight
inclination to each other.
And in order that our said invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing a longitudinal section of two pipes or tube
lengths as fitted with our improved joint or connection.
In carrying out our invention as shown on the drawings one tube end, E 1, at a
joint is made with an enlargement which is in the form of a sphe. ical fancet, F, and
is concave or is largest at its extreme edge. The other tube end, E 2, is also made
with an enlargement but the extreme end is contracted beyond the enlargement so
as to form a convex spherical spigot, S, adapted to enter the spherical faucet, F, of
the other tube end, E1. Flange rings, R, are put on each tube end and are
connected by bolts, B, which may be screwed up more at one side than at the other
when the two tube lengths are to be at a slight angle to each other. A packing, P,

page_text: of suitable compressible material is inserted between the joint surfaces of the
faucet, F, and spigol, S. The enlargements may be formed on the tube
ends, E1, E2, by means of suitably shaped expanding tools, or in any other
convenient way.
Hasing 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:
In forming joints or connections for pipes or tubes making a spherical fancet on
one end of a length of pipe or tube and a spherical spigot on one end of another
Jength of pipe or tube substantially as and for the purposes hereinbefore
described.
