PROVISIONAL 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 to be as follows, that is to say :-
This Invention has for its object an improved mode of applying joints or connec-
tions to plain-ended pipes or tubes, one advantage of which is that it will allow of the
pipes or tubes being packed in the smallest possible space for conveyance to a
distance.
In carrying out the Invention a joint or connection between two pipe or tube
lengths is formed by means of a pair of flange rings arranged to be drawn towards
each other by bolts, combined with a band or ring of lead or other suitable compressible
metal or material and an outer band or ring of iron, steel, or other metal of suffi-
cient strength. The lead or compressible ring covers the joint at the ends of the
pipe or tube lengths, and the outer ring covers the lead or compressible ring and
extends over short cylindrical necks formed on the flange rings. The bolts connecting
the flange rings pass outside of the outer confining band or ring; and when the
flange rings are drawn together their necks compress the inner band or ring of lead
or compressible material. The edges of the necks of the flange ring may be shaped
with a single or double bevil to act wedge-ways ou the compressible ring. If found
desirable pins may be fixed in the ends of the pipe or tube lengths to prevent
separation of the joint pieces from theu:; or the ends of the pipe or tube lengths
may be roughened in any convenient way for the same purpose.

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:
This Invention has for its object an improved mole of applying joints or connec-
tions to plain-ended pipes or tubes one advantage of which is that it will allow of
the pipes or tubes being packed in the smallest possible space for convoyance to a
distance.
In carrying out the Invention a joint or connection between two pipe or tube
lengthis is formed by means of a pair of flanged rings made with short cylindrical
necks and arranged to be drawn towards each other by bolts, combined with a band
or ring of lead or other suitable compressible metal or material and an outer band
or ring of iron, steel, or other metal of sufficient strength. If found desirable pins
may be fixed in the ends of the pipe or tube lengths to prevent separation of the
joint pieces from them; or the ends of the pipe or tube lengths may be roughened
in any convenient way for the sante purpose.
And in order that the said Invention and the manner of performing the same may
DC77

page_text: be properly understood we hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing our improvements.
Figures, 1, and 2, are longitudinal sections of two modifications of our improved
pipe joint. In these drawings the same reference letters are used to mark the same
or like parts wherever they are repeated.
In the modification shown in figure, 1, a joint or connection between two pipe
or tube lengths, A, A 1, is formed by means of a pair of flanged rings, B, B 1, arranged
to be drawn towards each other by bolts, C, combined with a band or ring, D, of
lead or other suitable compressible metal or material and an outer band or ring, E,
of iron or steel or other metal of sufficient strength. The lead or compressible
ring, D, covers the joint at the ends of the pipe or tube lengths, A, A 1, and the
outer ring, E, covers the lead or compressible ring, D, and extends over short cylin-
drical necks, F, F 1, formed on the flanged rings, B, B1. The bolts, C, connecting
the flanged rings pass outside of the outer confining band or ring, E, and when the
flanged rings are drawn together their necks, F, F1, compress the inner band or
ring, D. The edges of the necks, F, F 1, of the flanged rings, B, B1, are shaped
with a single bevil to act wedge-ways on the compressible ring, D.
The modification shown in figure, 2, is similar to that shown in figure, 1, except
that the edges of the necks, F, F1, of the flanged rings, B, B 1, are formed with a
double bevil.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
Forming a joint or connection between two pipe or tube lengths by means of a
pair of flanged rings drawn towards each other by holts so as to compress a band or
ring of lead or other suitable compressible metal or material confined by an outer
band or ring of iron, steel, or other metal of sufficient strength substantially as
hereinbefore described.
