PROVISIONAL SPECIFICATION
Improvements in Couplings for Pipes on Railway Trains.
We, MARIE FERDINAND LANCRENON, Engineer, of No. 45 Rue de Rennes,
Paris in the Republic of France, and GEORGE WILLIAM ADOLPHUS
FITZGEORGE, of 2 Bryanston Place, Bryanston Square in the County of
Middlesex, Colonel retired, do hereby declare the nature of this invention to be
as follows:-
This invention relates to couplings for pipes such as are used for conducting
steam or hot water for heating, or compressed or rarefied air for working
brakes or signals, on railway trains.
A complete coupling from carriage to carriage, according to this invention,
consists of two tubular parts each of which may be of flexible tube, or one of
which may be of flexible tube and the other of rigid tube connected by a spherical
joint to the pipe on the carriage. In either case the two parts which hang freely
down are united by a metallic coupling consisting of two equal and syminetrical
halves each of which is of the following description. It consists of a tubular part
which may be screwed to receive a metal union or shaped to have a flexible tube
wired on it. The passage through this tubular part bends at right angles to a
circular mouth, which opens through a flat face and is surrounded by a ring of
packing material. The two halves of the coupling being put together face to face,
with their two openings coinciding, are held together in either of two ways,
according as they are intended to remain more or less permanently coupled. When
they are to remain permanently coupled, as in the case of a train made up to
remain without change of carriages, each of the tubular arms has a projecting
bracket having a setting screw, so arranged that the end of the screw carried by
the bracket of the one half bears centrally on the back of the other half, the two
halves having their packed faces thus pressed firmly together.
When the coupling has to be frequently disconnected, each half is made with a
segmental undercut groove under a bracket projecting from its tubular part, and
with a segment projecting beyond its flat face, these parts being so arranged that
when the two parts are held face to face but with their tubular parts at an angle to
one another, the segment of the one can be engaged under the groove of the other,
and then, on turning the halves till their tubular parts come into line with one another,
the two faces are pressed firmly together by the wedging action of the brackets in the
grooves, which are made slightly taper. In some cases it is of advantage to make a
tubular part having a half coupling of the one kind at its one end and a half
coupling of the other kind at its other end, and to use this as an intermediate part
connecting the flexible tube to the spherically jointed tube. The spberical joint
consists of several parts, the first is sliaped as the zone of a hollow sphere attached
to a pipe, the second is a socket spherically shaped internally to receive the zone,i
the third is a ring which screws on to the socket, and presses an inner ring and
packing, put on in halves, against the spherical surface.
It is of advantage to provide each half coupling with a hook by which it and
the tube to which it is attached can be suspended when the coupling is
lisconnected.

We, MARIE FERDINAND LANCRENON, Engineer, of No. 45 Rue de Rennes,
Paris in the Republic of France, and GEORGE WILLIAM ADOLPHUS
FITZGEORGE, of 2 Bryanston Place, Bryanston Square, in the County of
Middlesex, Colonel retired, 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 couplings for pipes such as are used for conducting
steam or hot water for heating, or compressed or rarefied air for working brakes
or signals, on railway trains.
We shall describe the invention referring to the accompanying drawings.
Fig. 1 is a side view of a separable coupling from carriage to carriage.
Fig. 2 is a section of the ball joint.
Figs. 3. and 4 are respectively elevation and section of part of the coupling
shewn in Fig. 1.
Figs. 3 and 4 are respectively elevation and section of separable coupling.
Fig. 5 is an elevation of permanent coupling from carriage to carriage.
Fig. 6 is a plan of the coupling.
A complete coupling from carriage to carriage according to this invention as
shewn in Fig. 1 consists of two tubular parts, each of which may be of flexible
tube as A; or one of which may be of flexible tube A and the other of
rigid tube B connected by a spherical joint C, (shewn on an enlarged scale
in Fig. 2) to the pipe on the carriage. In either case the two parts D, E
which hang freely down are united by a metallic coupling F (as shewn
on an enlarged scale in elevation Figs. 3 and 34 and section in Figs. 4
and 4) consisting of two equal and symmetrical halves each of which is of the
following description. It consists of a tubular part G which may be screwed to
receive a metal union or shaped to have a flexible tube wired on it. The passage
through this tubular part bends at right angles to form a circular mouth, which
opens through a flat face and is surrounded by a ring g of packing material. The
two halves of the coupling being put together face to face, with their two openings
coinciding, are held together in either of two ways, according as they are intended
to remain more or less permanently coupled. When they are to remain
permanently coupled, as in the case of a train made up to remain without change
of carriages, as shewn in Figs. 5 and 6, each of the tubular arms of the coupling F
has a projecting bracket g' having a setting screw, so arranged that the end of the
screw carried by the bracket of the one half bears centrally on the back of the
other half, the two halves having their packed faces thus pressed firmly
together.
When the coupling has to be frequently disconnected as in Figs. 3, 4, 3 and 44
each half is made with a segmental undercut groove g under a bracket projecting
from its tubular part, and with a segment g³ projecting beyond its flat face, these
parts being so arranged that when the two parts are held face to face but with
their tubular parts at an angle to one another, the segment g³ of the one can be
engaged under the groove g2 of the other, and then, on turning the halves till
their tubular parts come into line with one another; the two faces are pressed
firmly together by the wedging action of the brackets g³ in the grooves g these
parts being made slightly taper. In some cases, as shewn in Figs. 1, 3 and 4, it is
of advantage to make a tubular part G' having a half coupling of the one kind F
at its one end and a half coupling of the other kind F at its other end, and to use
this as an intermediate part connecting the flexible tube A to the spherically

page_text: jointed tube B. The spherical joint C shewn in Fig. 2 consists of several parts,
the first, c, is shaped as the zone of a hollow sphere attached to a pipe, the
second, e', is a socket spherically shaped internally to receive the zone, the third is
a ring which screws on to the socket c' and presses an inner ringe and packing c
put on in halves, against the spherical surface.
It is of advantage to provide each half coupling with a hook H by which it
and the tube to which it is attached can be suspended when the coupling is
disconnected.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim in respect of pipe couplings on railway trains is :-
1. The separable coupling F constructed substantially as described with
reference to Figs. 3 and 4^.
2. The permanent coupling F substantially as described with reference to
Figs. 5, 6 and 4.
3. The ball joint C, substantially as described with reference to Fig. 2.
4. The combination of the flexible pipe A, the couplings F and F, the metal
pipe B, and the ball joint C, constituting a readily separable coupling from carriage
to carriage, substantially as described with reference to Fig. 1.
5. The combination of two ball joints C and the permanent coupling F¹ with
flexible or bent pipes, constituting a permanent coupling from carriage to carriage,
substantially as described with reference to Fig. 5.
