Improvements in Pipe Connections.
I, WILLIAM PHILIPPS WENHAM of Wenham and Waters Limited, Paragon
Works, Croydon, in the County of Surrey, Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to pipe connections, and is mainly useful for hot water
circnlating systems, although it may be used for gas and other connections where
circumstances render it desirable.
In hot water circulating systems it is frequently desired to have not only a
horizontal inflow and returu pipe but also to have vertical connections from such
pipes, and as the horizontal pipes are usually placed one directly above another it
is necessary to curve or bend the vertical pipe from the return so as to pass the
inflow pipe.
According to this invention it is proposed to form socket pieces or joints con-
taining both an inflow and return, and also an inflow and return connection at
right angles thereto, the return connection passes directly through the inflow pipe,
which at this point is divided and virtually forins a water or gas jacket around the
return flow, although it would be obvious that the return flow may form the water
jacket around the inflow.
With the construction as first described the entire section can be made in a
single casting provided with the usual sockets for the reception of the connecting
pipes. The construction may also be carried out in wrought iron or pipes of other
material or with pipes of different materials.

Improvements in Pipe Connections.
I, WILLIAM PHILIPPS WENHAM of Wenham and Waters Limited, Paragon.
Works, Croydon, in the County of Surrey, Manufacturers, 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 :-

circulating systems, although it may be used for gas and other connections where
circumstances render it desirable.

horizontal inflow and return pipe but also to have vertical connections from such

right angles thereto, the return connection passing directly through the inflow pipo
which at this point is divided and virtually forms a water or gas jacket around
the return flow, although it would be obvious that the return flow may form the
water jacket around the inflow.
With the construction as first described the entire section can be made in a
single casting provided with the usual sockets for the reception of the connecting
pipes. The construction may also be carried out in wrought iron or pipes of
other material or with pipes of different materials.
To clearly illustrato my invention reference is made to the accompanying
drawings in which :-
Fig. 1 is a view of one form of connection constructed according to my invention.
Fig. 2 is a view of another form.
Fig. 3 is a sectional elevation of Fig. 1.
Fig. 4 is a plan of same.
Fig. 5 is a section on line z- Fig. 3.
Fig. 6 is a right hand end view of Fig. 3, and
Fig. 7 is a view of a modification shown partly in section.
In Figs. 1, 3, 4, 5 and 6 the connection is shown as a casting comprising the
inflow pipe a and return pipe b the latter having a connection c at right angles
thereto passing through the pipe a which is enlarged at d to form a chamber or
passage around the connection o. The inflow pipe a is also provided with a
connection e. In this construction the pipes a and b are cast with flanges f, g, at
either end which connect them together, and the connections c, e, are also cast with
a flange h.
In Fig. 2 a simpler construction is illustrated, the flanges being dispensed with,
the pipes a and b having simply spigot and socket ends and the connections c, e,
sockets (or it may be spigots).
In Fig. 7 a construction is illustrated in which the pipes a consist of a casting
provided with a chamber d having a separate wall d' forming a passage through
which the connection c may be carried or through which any other pipe or part
may be taken when the pipe a would otherwise come in the way of same. Such
pipe a may or may not be provided with a connection such as e.
The pipe a may be provided with flanges f, g, as shown, or with socket and
spigot ends or other means for connecting same to pipes, and this applies also to
the other arrangements shown.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A connection for pipes consisting of pipe sections provided with a branch
connection or connections all formed in one piece, substantially as and for the
purpose described.
2. A connection for pipes consisting of pipe sections provided with branch
connections one of which latter passes through one of the main pipes which is
enlarged to receive it, substantially as and for the purpose described.
3. A connection for pipes consisting of a pipe section having a passage way
through an enlargement of same, and means for connecting such section to other
pipes, substantially as and for the purpose described.
4. The improvements in pipe connections substantially as and for the purposes
described, and as illustrated in the drawings.
