PROVISIONAL SPECIFICATION.
An Improved Coupling or Joint for Malleable Iron and other Tubes,
and Pipes.
I, JAMES MENZIES, of Phoenix Tube Works, Dalmarnock Bridge, Glasgow,
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
I slip over the ends of the tubes to be connected, one flange for each tube.
I construct or form one of the flanges with a circular or other shaped recess or
groove into which is fitted a circular or other shaped rib or pap formed on or
attached to the other flange. 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 preferably left between the faces of
the flanges for the reception of an india-rubber ring or other equivalent packing;
said coupling or joint thus forming an effective water or gas tight joint when the
flanges are clamped up.
Dated this 16th day of March 1894.

COMPLETE SPECIFICATION.
An Improved Coupling or Joint for Malleable Iron and other Tubes
and Pipes.
I, JAMES MENZIES, of Phoenix Tube Works, Dalmarnock Bridge, Glasgow,
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 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 and as is illustrated in section in Figure 1
of the annexed drawings, I employ a pair of annular flanges A, A' which I slip
over the ends of the tubes B to be connected, one flange for each tube. I construct
or form one of the flanges A with a circular or other shaped recess or groove C
into which is fitted a circular or other shaped rib or pap D formed on or attached
to the other flange A'. The position of the flanges A, A' upon the ends of the
tubes B is such, that a space is left between the faces of the flanges for the purpose

page_text: of allowing the necessary tightening up, by connecting the flanges by an
arrangement of bolts and nuts E. A space is preferably left between the faces of
the flanges A. A¹ as shown for the reception of an india rubber ring F or other
equivalent packing; said coupling or joint thus forming an effective water or gas
tight joint when the flanges are clamped up.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is.
1st. The general arrangement, construction and combination of the parts
constituting my improved coupling or joint for malleable iron and other tubes and
pipes, substantially as hereinbefore described and shown in the accompanying
drawings.
2nd. In couplings or joints for tubes and pipes, forming or providing one of the
flanges A with a recess or groove C and the other flange A¹ with a ring or pap D,
with an india-rubber ring F or its equivalent, substantially in the manner as
herein before described and shown in the accompanying drawings.
