PROVISIONAL SPECIFICATION.
Improvements in Pipe Couplings.
I, ALEXANDER SPENCER, of 77 Cannon Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to a construction of pipe coupling designed to
enable the adjacent flexible ends of four or more pipes to be connected together in
two or more pairs, by one engaging operation.
For this purpose the pipe coupling is made in parts adapted to be readily
engaged with and disengaged from each other and each formed with two or more
separate passages, one end of each of which is adapted to be connected to the end of
a flexible pipe, the other end being arranged to come opposite the corresponding end
of the corresponding passage in the other part coupling when the parts of the
coupling are brought together.
According to one construction the pipe coupling is made in two parts provided
with interlocking jaws or engaging parts having inclined or screw like surfaces
similar to those provided in the well known Westinghouse coupling. Each part
coupling is formed with two passages arranged parallel to each other, and
terminating at the one or outer end in two parallel pipes or nozzles arranged at an
angle to the periphery of the part coupling, and at the other or inner end in two
holes formed in the flat or abutting side of the part coupling and arranged one on
either side of the centre thereof. Each hole is or may be provided with a ring
similar to those ordinarily employed for forming an abutting or jointing surface
with the corresponding ring in the opposite hole of the other part coupling when
the two parts of the coupling are connected together..
Pipe couplings constructed as described are specially suitable for connecting
together the lengths of gas or other fluid supply pipes used on railway carriages
for gas lighting, or brake-operating and heating purposes..

Improvements in Pipe Couplings.
I, ALEXANDER SPENCER, of 77 Cannon Street, in the City of London,
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 :-
This invention has reference to a construction of pipe coupling designed to
enable the adjacent flexible ends of four or more pipes to be connected together
in two or more pairs, by one engaging operation.

page_text: For this purpose the pipe coupling is made in parts adapted to be readily engaged
with and disengaged from each other and each formed with two or more separate
passages one end of each of which is adapted to be connected to the end of a
flexible pipe, and the other end of each passage being arranged to come opposite
the corresponding end of the corresponding passage in the other part coupling
when the parts of the coupling are brought together.
Figs. 1 to 5 inclusive of the accompanying drawings represent one construction
of pipe coupling suitable for connecting together the ends of two adjacent pairs of
pipes, Fig. 1 being a side elevation of one half of the coupling, Figs. 2 and 3
showing sections on the lines x and y y respectively of Fig. 1; Fig. 4 an
elevation of the entire coupling put together, and Fig. 5 a plan thereof.
In this construction the pipe coupling is made in two halves or parts 1 1*
provided with interlocking jaws or engaging parts 2, 2ª having inclined or screw
like surfaces similar to those provided in the well known Westinghouse coupling.
Each part coupling is formed with two passages 3 and 4 arranged parallel to each
other and terminating at their outer ends in two parallel pipes or nozzles 5 and 6
arranged at an angle to the periphery of the part coupling, and at the other or
inner ends in two holes 7 and 8 formed in the flat or abutting side of the part
coupling and arranged one on either side of the centre thereof (Fig. 1). Each
of the holes 7 and may, as shown, be provided with a ring 9 similar to
those ordinarily employed for forming an abutting or jointing surface with the
corresponding ring in the opposite hole of the other part coupling when the two
parts of the coupling are connected together as shown in Figs. 4 and 5, each ring
being held in place as usual by a slotted tube or cage 10 and screw cap 11.
Pipe couplings constructed as described are specially suitable for connecting
together the lengths of gas or other fluid supply pipes used on railway carriages
for gas lighting, brake-operating, and heating purposes.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A pipe coupling made in parts adapted to be readily engaged with and
disengaged from each other and each formed with two or more separate passages
one end of each of which is adapted to be connected to a flexible pipe and the
other end being arranged to come opposite the corresponding end of the corre-
sponding passage in the other part coupling when the parts of the coupling are
brought together, substantially as described.
2. My improved pipe coupling constructed substantially as described and shown.
