Improvements in Flexible Pipe Connections.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to flexible pipe joints, and has for its object an expan-
sible and contractible metallic pipe connection, whereby the distance between
the termini of the pipe may be varied within reasonable limits and lateral move-
ment of the pipe also had without causing loss of the fluid passing through said
pipe.
Metallic couplings or pipes, may be made of any suitable form. The first
coupling is provided with a threaded opening in which is threaded a connecting
joint provided with annular shoulders that forms a tight joint with the first
coupling. The outer portion of said connecting joint flares outwardly. Spider
seats are formed on the inner portion of said joint and in said seats are seated
the spider. The second coupling has a threaded opening in which is threaded
a cap that is provided with a seat in which is seated the spiral spring. A washer
is located on the upper portion of said spring and forms a seat for the nipple of
the spider. A packing ring of bevel seat formation is located intermediate of
the second coupling and connecting joint.
When it is desired to couple up the two couplings, the packing ring is slipped
over the connecting joint until it engages with the outwardly flaring portion
of said connecting joint. The connecting joint is then inserted through the
shoulder opening of second coupling and is screwed into the opening of first
coupling until the shoulder engages with said coupling. Spiral spring is then
seated in the seat of cap and the washer slipped over the nipple of the spider.
The spider is seated in the spider seats of the connecting joint and the cap screwed
into the opening of second coupling until a tight joint is formed.
It will readily be seen that this form of coupling permits easy rotative move-
ment of the two parts of the coupling, and by locating the several joints in
planes at right angles to each other, the complete pipe may be expanded and
contracted longitudinally, and free lateral movement of the pipe also had.

page_text: I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 flexible pipe joints, and has for its object an expan-
sible and contractible metallic pipe connection, whereby the distance between
the termini of the pipe may be varied within reasonable limits and lateral move-
ment of the pipe also had without causing loss of the fluid passing through said
pipe.
The annexed drawings and the following description set forth in detail, certain
mechanism embodying the invention; such disclosed means constituting but
one of various mechanical forms in which the principle of the invention may
be used.
In said annexed drawings:-
Figure I is a plan view of several joints of pipes provided with my flexible
connections; Figure II is a central horizontal longitudinal view taken through
one joint, and Figure III is a detail view of the connecting joint and spider.
Metallic couplings or pipes, respectively A and B may be made of any suit-
able form. The coupling A is provided with a threaded opening a in which is
threaded a connecting joint C provided with annular shoulders c that forms a
tight joint with the coupling A. The outer portion of said connecting joint
flares outwardly Spider seats are formed on the inner portion of said joint
and in said seats is seated the spider D. Coupling B has a threaded opening b
in which is threaded a cap E which is provided with a seat e in which is seated
the spiral spring el. A washer is located on the upper portion of said spring
and forms a seat for the nipple f of the spider D. A packing ring G of bevel
seat formation is located intermediate of the coupling Band connecting
joint C.
When it is desired to couple up the couplings A and B, the packing ring G
is slipped over the connecting joint until it engages with the outwardly flaring
portion of said connecting joint. The connecting joint is then inserted
through the shoulder opening of coupling B and is screwed into the opening a
of coupling A until the shoulder e engages with said coupling. Spiral spring el
is then seated in the seat of cap E and the washer slipped over the nipple f
of the spider 1. The spider is seated in the spider seats of the connecting
joint and the cap E screwed into the opening of the coupling B until a tight
joint is formed.
It will readily be seen that this form of coupling permits easy rotative move-
ment of the two parts of the coupling, and by locating the several joints in
planes at right angles to each other, the complete pipe may be expanded and
contracted longitudinally, and free lateral movement of the pipe also had.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, 1 declare that what I claim is:-
:―
1. In a flexible pipe joint, or connection, the combination of two couplings, a
connecting joint rigid with one coupling, a packing ring located intermediate
of said connecting joint and second coupling and a pressure device exerting
pressure against said connecting joint and packing ring, substantially as set
forth.

page_text: 2. In a flexible pipe joint or connection, the combination of two couplings, a
connecting joint rigid with one coupling and loosely fitting in the second coupl-
ing, a packing ring interposed between said second coupling and connecting
joint, and a spring pressure device having bearing against said connecting
joint, substantially as set forth.
3. In a flexible pipe joint or connection, the combination of two couplings,
one provided with a connecting joint, a conical packing ring interposed between
said second coupling and said connecting joint, and a spring pressed spider seated
in said connecting joint, substantially as set forth.
4. In a flexible pipe joint or connection, the combination of two couplings,
one of said couplings provided with a connecting joint having an annular shoulder
bearing against said coupling, a screw cap threaded in said second coupling,
carrying a spring and a spider said spider having bearing against said connecting
joint and a packing ring interposed between said connecting joint and second
coupling, substantially as set forth.
