Steam Heating Apparatus for Railway Carriages.
I, HAROLD IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus for heating railway carriages by steam
supplied from the locomotive boiler. For this purpose each carriage of the train
has fixed below its underframing a pipe which at each end is provided with a
suitable union, so that, in making up a train, the pipe of each carriage can be
coupled by a flexible hose to that of the next carriage. The pipe of the first
carriage is flexibly connected to a pipe communicating with the locomotive boiler,
which pipe is provided with a stop cock or valve under command of the driver and
also with a regulating valve which he can adjust so that the steam passing into the
train pipe shall not exceed a certain moderate pressure. The pipe of the last
carriage may be provided with a stop cock or steam trap for running out water of
Under a seat in each compartment of each carriage is fixed a
cylindrical vessel or heater which communicates by a pipe with the pipe below the
underframing from which it is charged with steam, and into which water of
condensation may at the same time escape. Instead of one heater there may be
several in a compartment. For the first and second class compartments it is
preferred to provide in the pipe leading to the heater a stop cock or valve having
a pull or handle extending up into the compartment so that passengers can turn on
more or less steam at will. This stop cock or valve is preferably provided with a
lateral escape orifice so that when the supply of steam from the train pipe is cut
off, water of condensation can escape from the heater above.

COMPLETE SPECIFICATION.
Steam Heating Apparatus for Railway Carriages.
I, HAROLD IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, 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 apparatus for heating railway carriages by steam
supplied from the locomotive boiler. For this purpose, each carriage of the train
has fixed below its underframing a pipe which at each end is provided with a
suitable union, so that in making up a train the pipe of each carriage can be

which pipe is provided with a stop cock or valve under command of the driver and
also with a regulating valve which he can adjust so that the steam passing into the

The pipe of the last carriage may be provided with a stop cock or steam trap for
running out water of condensation.

cylindrical vessel or heater C which communicates by a pipe P with the train
pipe T below the underframing, from which it is charged with steam, and into
which water of condensation may at the same time escape. Instead of one heater,
there may be several in a compartment. For first and second class compartments
it is preferred to provide in the pipe leading to the heater a stop cock or valve S
having a pull or handle H extending up into the compartment so that passengers
can turn on more or less steam at will. This stop cock or valve is preferably
provided with a lateral escape orifice, so that, when the supply of steam from the
train pipe is cut off, water of condensation can escape from the heater C above.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
-
Apparatus for heating railway carriages consisting of vessels placed under seats,
and communicating with a pipe conveying steam from the locomotive boiler along
the train.
