page_text: I, WILLIAM HENRY WITHINGTON of 37 Brown Street, Manchester in the County
of Lancaster Sanitary Engineer do hereby declare the nature of this invention to
be as follows:-
This Invention relates to the means for joining or connecting lead, indiarubber
and other pipes and has for its object to permit such joints or connections to be
made readily and without the use of solder.
These improvements consist in a means for making the joints or connections of
lead, indiarubber and other pipes as hereinafter described.
I construct a short metallic tube within which I form an annular projection
which may be rectangular in section or have a groove turned or formed in one or
both its surfaces. The hole through the annular projection may correspond with
the internal diameter of the pipe to be joined or connected.
The short tube is tapped with a female screw at each end into which may be
fitted suitably shaped and similarly screwed rings having holes corresponding to
the external diameter of the pipe to be joined. In some cases a cock, valve or
other fitting may be fitted to one end of the short tube when one of the rings only
will be required.
The rings may have hexagonal or other projection or surface thereon by means
of which they may be turned by a spanner or other apparatus.
In making the joint or connection the end of the pipe to be joined is inserted
through the ring until its end comes into contact with the annular projection and
the ring is then screwed home, when the end of the pipe is compressed between
the annular projection and the ring and a tight joint is made.
For low pressures the annular projection may be square and for higher pressures
it may be grooved.
The joint may in some cases be additionally secured by the employment of
indiarubber, lead, leather or other similar washers or by yarn asbestos or other
suitable packings.

page_text: Improvements in the Means for Joining or Connecting Lead,
Indiarubber, and other Pipes.
I, WILLIAM HENRY WITHINGTON of 8, & 10 Brown Street Manchester in the
County of Lancaster Sanitary Engineer, 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 the means or devices employed for joining or con-
necting lead indiarubber and other pipes and has for its object to permit such
joints or connections to be readily made without the use of solder or cement,
These Improvements consist in the construction and application of a connecting
device consisting of a short tube internally screwed at each end and provided with
an internal annular projection in combination with one or two externally screwed
rings or ferrules adapted to screw into the short tube and to fit upon the end or
ends of the pipe to be joined.
And in order that this my Invention may be more readily understood and
carried into practical effect I have hereunto appended a sheet of Drawings and
will now proceed to describe the same having reference to the letters thereon,
similar letters being employed in each of the figures to denote similar parts.
Fig. 1 represents a longitudinal section and Fig. 2 a side view of portions of
two tubes or pipes having their ends connected according to these improvements.
A is a short tube internally screwed at each end and having formed therein an
annular projection B which may be rectangular in section or, as represented, have
a groove turned or formed in one or both its faces.
The clear opening through the projection B may correspond with or be some-
what larger than the internal diameter of the pipes to be connected. D D are two
externally screwed rings or ferrules the internal diameters of which correspond with
the external diameters of the pipes or tubes.
The short tube or coupling A and the rings or ferrules D have by preference
cast or formed upon, them hexagonal flanges collars or projecting parts whereby
they may be held or turned by spanners or other apparatus. CC are the ends of
the connected pipes.
A cock, valve or similar fitting may be connected to a pipe by screwing or
otherwise connecting it to one end of the tube or coupling A in which case the
cock valve or other fitting will take the place of one of the rings or ferrules D.
A branch pipe may be connected by making the tube or coupling A similar to
an ordinary T coupling the internal annular projection being formed on each side
of the perpendicular branch. Two branch pipes may similarly be connected by
making the tube or coupling A equivalent to an ordinary cross coupling. In
either case the branch pipe or pipes may be connected to the perpendicular branch
or branches of A. by screwed ferrules similar to those shown at D.
In making the joint or connection the end of the pipe to be joined or connected
is inserted through the ferrule when the end if practicable and desirable may be
slightly coned. The ferrule holding the end of the pipe is then inserted into the

page_text: coupling piece A and is screwed up until the end of the pipe is compressed between
the annular part of A and the ferrule, effecting a tight joint. For low pressures
the annular projection may be square in section or of other convenient form but
for high pressures I prefer to groove it on each face as represented in Fig. 1.
When indiarubber tubes are connected by the hereinbefore described means or
device it may be necessary in some cases to insert a short light metallic liner within
the ends of the tube to prevent its collapsing.
The joint may in some cases be additionally secured by the employment of
indiarubber lead leather or other similar washers or by yarn asbestos or other
suitable packing.
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:-
(1.) As a device or means for connecting the ends of lead indiarubber and other
pipes, the combination and arrangement of a screwed coupling having an internal
annular projection B, with two or more screwed ferrules, substantially as herein-
before described with reference to the accompanying sheet of Drawings
(2.) As a device or means for connecting the end of a lead indiarubber or
other pipe with a cock valve or similar fitting, the combination and arrangement
of a screwed coupling having an internal annular projection, with a screwed
ferrule fitting on the end of the pipe, substantially as herein before described with
reference to the accompanying sheet of Drawings.
(3.) In a coupling or device for connecting the ends of lead india-rubber and
other pipes, a screwed tube having an internal annular projection substantially as
herein before described.
