Improved System for Heating Railway Carriages.
ROBERT ROBERTS JARDINE, Clerk to H.M. Office of Works Birmingham,
Oughton Place, Camp Hill, Birmingham ALBERT JOHN KALLAWAY Hot
Water Engineer, Hurst Street Birmingham do hereby declare the nature of this
invention to be as follows:-
Small wrought steam pipes as A in drawing Fig. 1 are carried underneath the
railway carriages near to the side of same, and at the centre of each compartment
a larger steam pipe B of the necessary dimension is joined on to the smaller pipe at
right angles, and carried along the compartment to the other side just underneath
the grating C which is let in level with the floor, through which the hot air rises
and diffuses heat of an equal temperature throughout the compartment. The
larger pipe is again joined by the small one, which small pipe is carried along &
connected to the large pipe which runs at right angles to the small one, underneath
the centre of the other compartment, and in like manner the whole train is fitted
up. The pipes of the one carriage are joined to that of the other carriage or engine
by a steam flexible tube or such like arrangement. The whole of the pipes are.
heated by the steam from the engine. To prevent the pipes from becoming cool
they are boxed up at D.
Figure 1 represents plan of carriage showing the pipes running underneath the
carriage, also the grating let into floor of same.
Figure 2 represents the section through E F showing the large pipe, boxing to
same, & grating.

Birmingham ALBERT JOHN KALLAWAY Hurst Street Birmingham Hot Water
Engineer &c. 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 :-
Improved system of heating railway carriages from the engine. This is carried
out in the following manner :-
A small steam pipe as C in drawing is connected to engine and carried under-
Death railway carriage and near to side of same as far as the centre of the
1st compartment where it is connected to a large steam pipe D, which latter pipe
runs at right angles to the small feed pipe, to the other end of the compartment or
carriage, where it is again connected to the small pipe, which small pipe is carried
on to the centre of the next compartment where it is similarly connected to

page_text: another large steam pipe and this arrangement is carried on throughout all the
compartments of the train.
The pipe of the one carriage is connected to the pipe of the other carriage by a
coupling pipe.
At the end of the train the small pipe is connected by a coupling pipe F to the
return pipe G which latter pipe empties itself into the tank of engine.
A perforated grating E of suitable metal is let into the centre of the floor of
each compartment directly over and in proximity to the large steam pipe.
The large steam pipes are covered in by boxings H to prevent them from cooling,
and if it were found necessary, the small pipes could be covered with a solution for
the same purpose.

Figure 3 représents section through A B of Figure 1 showing grating E; large
pipe D; & boxing to same at H.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is
1. Carrying of small steam pipe underneath railway carriage which is
connected to
II. Large steam pipe runuing directly underneath centre of each compartment,
in floor of which is let in a
III. Suitable perforated grating running parallel and directly over the large
steam pipe.
IV. Small steam flow pipe commencing from engine and small return pipe
terminating in engine.
