PROVISIONAL SPECIFICATION.
An Improved Coupling or Joint for Malleable Iron and other Tubes
or Pipes.
I, JAMES MENZIES of Phoenix Tube Works, Dalmarnock in the County of Lanark,
North Britain, Tube Manufacturer do hereby declare the nature of this invention to
be as follows:→→
This Invention relates to an improved joint for malleable iron and other pipes or
tubes for conveying steam, water, gas, and the like, and my Invention has for its
object the production of a joint of simplicity in construction and capable of being
readily fixed.
In the carrying out of my Invention I employ a pair of annular flanges which 1
slip over the ends of the tubes to be connected, the one flange for each tube. I con-
struct the flanges widened out at the part where they surround the tubes and I form
the inner periphery of each of the flanges with a recessed portion for the reception
of a steel or other metal ring which is slipped over the junction of the tubes, the said
ring being clamped by and between the said recessed portions of the flanges. The
position of the flanges upon the ends of the tubes is such that a space is left between
the faces of the flanges for the purpose of allowing the necessary tightening up, by
connecting the flanges by an arrangement of bolts and nuts. A space is left between
the edges of the steel ring and the closed end of each of the recesses in the flanges for
the reception of an india-rubber ring or other equivalent packing, which forms an
effective water or gas tight joint when the flanges are clamped up.

COMPLETE SPECIFICATION.
An Improved Coupling or Joint for Malleable Iron and other Tubes
or Pipes.
1, JAMES MENZIES of Phoenix Tube Works, Dalmarnock, in the County of Lanark,
North Britain, Tube Manufacturer, 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 :—
This Invention which relates to an improved coupling or joint for malleable iron
and other tubes or pipes for conveying steam, water, gas and the like has for its
object the production of a coupling or joint which owing to the simplicity of its con-
struction is very efficient and easily connected or fixed.
In order that my said Invention may be more readily understood and easily carried
into effect, I will proceed to describe the same reference being made to the annexed
sheet of drawings, Figure 1 of which is a perspective view, and Figure 2, a section
of my improved joint or coupling.
Referring to the said Figures 1 and 2 1 employ a pair of metal flanges A, each of
which I slip over the ends of the tubes or pipes B which are to be connected, the said
flanges A are widened out or made thicker as shewn at a, so as to enable a recess or
hollow part a', being formed on their inside, and into which is fitted a steel or other
metal ring C, this ring being so placed as to cover the junction b, of the two tubes
or pipes ends. This ring is clamped by means of the two flanges A, and bolts and
nuts D, which also form an efficient and tight joint around each pipe or tube by their
pressing the india rubber or other suitable packing rings E around the outside
circumference of the said pipes or tubes the said packing rings being fitted into the
гр.

page_text: angled spaces left between the inside peripheries a², of the flanges' recesses and the
outside edges c, of the rings C, thus forming a simple, easy and efficient coupling or
joint when clamped up; the said clamping being regulated by means of the space
left between the faces of the said flanges, through the medium of the bolts and
nuts D.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is―
First. The general arrangement, combination, and construction of the various parts
constituting my improved coupling or joint for malleable iron and other tubes or
pipes, substantially as herein before described.
Second. In couplings or joints for malleable iron and other tubes or pipes, the
employment of a pair of recessed flanges A, metal ring C, packing rings E, and bolts
and nuts D, all substantially as and for the purposes hereinbefore described and shewn
in the accompanying drawings.
