PROVISIONAL SPECIFICATION.
An Improved Pipe Joint.
1, FREDERICK CLEAVER, of "The Crofts," off Punt Road Richmond near
Melbourne in the Colony of Victoria Engineer, do hereby declare the nature of
this invention to be as follows:-
Heretofore it has been found to be a somewhat difficult and comparatively
expensive matter to make a simple and efficient joint between the ends of two
lengths of steam or other pipe.
Now the object of my invention is to provide a simple and efficient joint whereby
the ends of two lengths of piping can be readily connected and disconnected, and
which will when coupled together, be perfectly steam, air, or water tight.
Lengths of pipe are ordinarily coupled by means of outwardly projecting flanges
at their ends provided with holes at intervals through which bolts can be passed for
the purpose of drawing said flanges, and therefore the ends of the two lengths of
pipe, together. Now, according to my invention, the face of this flange or of the
end of each length of said pipe is formed with an annular recess corresponding in
size and position with the annular recess on the opposite end of the next length of
pipe.
Into each pair of these adjacent annular recesses is fitted a ring of soft metal,
which, when inserted, is rectangular in cross section, but which when the two
flanges on the ends of the lengths of pipe are drawn together is compressed at its
centre and compelled to assume the shape of a cross, the side arms of said cross
being forced out between the two flanges and thus forming a perfectly tight joint.

COMPLETE SPECIFICATION.
An Improved Pipe Joint.
I, FREDERICK CLEAVER, lately of "The Crofts" off Punt Road, Richmond,
near Melbourne in the Colony of Victoria, but at present residing at No. 8 Reed
Street, South Melbourne, near Melbourne aforesaid, 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 :—
Heretofore it has been found to be a somewhat difficult and expensive matter
to make a simple yet efficient joint between the ends of two lengths of steam or
other piping.
Now the object of my invention is to provide a simple and efficient joint whereby
the ends of two lengths of piping can be readily connected and disconnected, and
which when coupled together will be perfectly air, steam or water tight.
Lengths of piping are usually coupled together by bolts passed through outwardly
projecting flanges on their ends, such flanges being provided with holes at intervals,
through which said bolts can pass in order to draw said flanges, and therefore the
ends of the lengths of piping together.
Now, according to my invention, I make the face of each of these flanges on the
end of each length of piping with an annular recess corresponding in size and
position with the annular recesses on the opposite flange or end of the next length
of piping, and in each of these annular adjacent recesses I fit a ring of soft metal
which when first inserted is rectangular in cross-section, but which when the two
Price 8d1

page_text: flanges on the ends of the lengths of piping are drawn together, is compressed at its
centre, and compelled to assume the shape of a cross, the side arms of said cross
being forced out between the two flanges, thus forming a perfectly tight joint.
Referring to the accompanying drawings,
Figure 1 is a vertical central section of the adjacent ends of two lengths of
piping shewing them fitted with my improved pipe joint.
Figure 2 is a front elevation of the end of one of said lengths of piping, and
Figure 3 is a similar view to Figure 1, but showing the ring of soft metal after
the lengths of piping have been drawn together.
A-A represent the flanges which are formed on the ends of each length of
piping B. C-C represent the holes which are formed through said flanges to
receive bolts for the purpose of drawing said flanges, and therefore the ends of
the lengths of piping, close together. D-D represent the annular recesses which
are formed in each of the flanges A, and E represents the ring of soft metal which
is inserted in said recesses, as shewn in Figure 1, so that when the bolts F passing
through the flanges A are tightened up, said ring will be compressed into the form
of a cross, as illustrated in Figure 3, the side arms of said cross being forced out
between the flanges A-A, as shown, so as to form a perfectly tight joint.
It will be readily understood that a joint such as I have described will be simple
and inexpensive to make, and will be a very efficient one for many different purposes
where a face joint is required.
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 :-
The herein described pipe joint consisting of flanges formed on the ends of a
length of piping to be joined, and having adjacent annular recesses (such as D)
formed in the opposite end of each length of piping, a ring of soft metal (such as E):
being inserted in said adjacent annular recesses so that when said flanges are drawn
together by means of bolts provided for the purpose, said soft metal ring will be
compressed into the form of a cross, substantially as and for the purposes herein
described and explained and as illustrated in the accompanying drawings.
