IMPROVEMENTS IN FLEXIBLE OR UNIVERSAL PIPE JOINTS to be as follows
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I EDWARD GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex
Fellow of the Institute of Patent Agents do hereby declare the nature of said
Invention for "IMPROVEMENTS IN FLEXIBLE OR UNIVERSAL PIPE JOINTS
to be as
follows:-
"
The main feature of this new flexible or universal joint is its simplicity: it is
composed of three chief parts, viz a fixed part, formed with a flange, a coupling,
bolted to it and a movable part the whole forming a ball and socket joint.
Between the coupling and the fixed part there is an annular cavity of equilateral
triangular form in which a caoutchouc packing ring of circular section is inserted
in order to preserve a tight joint. This flexible or universal joint is applicable to
all kinds of pipe joints and is especially available for dredging boats or barges
where the line of floatation is continually changing; the ordinary joints often
cause breakage of the pipes whereas by this invention a breakage is rendered next
to an impossibility.

Fellow of the Institute of Patent Agents do hereby declare the nature of said
invention for "IMPROVEMENTS IN FLEXIBLE OR UNIVERSAL PIPE JOINTS" and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
The main feature of this new flexible or universal joint is its simplicity, and the
invention will be best understood by reference to the accompanying drawings.
This new joint is composed of three chief parts viz, a fixed part formed with a
flange; a coupling bolted to it, and a movable part, the whole forming a ball and
socket joint. Between the coupling and the fixed part there is an annular cavity
of equilateral triangular form in which an annular caoutchouc washer is inserted in
order to preserve a tight joint,
Figure 1 of the accompanying drawings is a front view of a flexible or universal
pipe joint constructed according to this invention. Figure 2 is a top view or plan
of same; Figure 3 is a vertical section through the middle; Figure 4 is a top view
or plan of the part marked B, the movable part is removed; Figure 5 is a
detached view of the movable part with the caoutchouc ring, and Figure 6 shows
the caoutchouc ring detached.
A is the movable part; a is the joint cover; B is the lower part of the joint;
C the caoutchouc ring; c Figure 4 the cavity formed by the pieces a and B in
which the caoutchouc ring is placed when the joint is complete; "the dotted lines
Figure 3 show one of the inclined positions of the joint.
This flexible or universal joint is applicable to all kinds of pipe joints and is
especially available for dredging boats or barges where the line of floatation is
.continually changing; the ordinary joints often cause breakage of the pipes whereas
by this invention a breakage is rendered next to an impossibility.
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
In flexible or universal pipe joints the combination of fixed part with movable
part and cavity for the reception of india rubber joint or ring as and for the
purposes set forth.
