Improvements in and Apparatus for Heating Railway Carriages,
Tram-cars, and other Vehicles.
I HENRY CORNES of 50 Renshaw Street, Hulme, Manchester, Shirt Manufacturer,
do hereby declare the nature of my invention to be as follows:-
The object of this invention is the special application of hot air, steam, hot water or
other suitable heating medium to the purpose of heating railway carriages tram cars
or other vehicles and consists in carrying a pipe beneath the vehicle and supplying the
same with hot water, steam or hot air say in the case of a railway train from the
boiler or furnace of the locomotive or in the case of a tram car or other single vehicle
from a special heating stove.
This pipe in the case of railway carriages is supplied with unions at either end to
facilitate its connection to the heating apparatus in the adjoining vehicles and with
stop cocks and draw off cocks for controlling the flow for emptying and withdrawing
any water or other fluid as required from time to time.
And in order to convey the heating medium to the interior of each vehicle-I
arrange a branch pipe rising from the pipe hereinbefore mentioned and which opens
into a copper or other metallic heating casing constructed with a flat top which is by
preference flush with the floor of the vehicle and this not only acts as the heating
apparatus for heating the vehicle but also as a foot warmer for the use of the
occupants-In this branch pipe a suitable stop cock or valve is conveniently disposed
for the passengers to actuate the same so as to open and close the communication
at will.

I HENRY CORNES of 50 Renshaw Street, Hulme, Manchester Shirt Manufacturer
do hereby declare the nature of my invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention is the special application of hot air, steam, hot water or
other suitable heating medium to the purpose of heating railway carriages, tram-cars
or other vehicles and consists in carrying a pipe beneath the vehicle and supplying the
same with hot water, steam or hot air say in the case of a railway train from the
boiler or furnace of the locomotive or in the case of a tram-car or other single vehiclo
from a special heating stove. This pipe in the case of railway carriages is supplied
with unions at either end to facilitate its connection with the heating apparatus in the
adjoining vehicles and with stop cocks and draw off cocks for controlling the flow for
emptying or withdrawing any water or other fluid as required from time to time.
And in order that this my said invention may be the more readily understood and
carried into practical effect I have hereunto annexed a drawing illustrative of my
improvements applied to a railway carriage and to a tram-car.
Fig. 1 represents a side view of a locomotive and railway carriage (partly in section)
with my improved heating apparatus applied.
Figs. 2 and 3 on a large scale represent a side sectional view and transverse section
respectively of a portion of the same railway carriage shewing my improvements more
clearly and Fig. 4 is a plan view of the top of the heating casing.
In all the views (a) is the heating pipe carried beneath the railway carriage (b) and
provided with unions (c) at either end to facilitate its connection with the similar
heating pipe of the adjoining carriage at one end and at the other end to facilitate its
connection with the steam space of the locomotive (d).
And in order to convey the heating medium say steam in this case to the interior of
each compartment of the railway carriage I arrange to each such compartment a
branch pipe (e) rising from the aforesaid main heating pipe (a) and which opens into
a copper or other metallic heating casing (f) constructed with a flat top (g) and
which is by preference flush with the floor of the vehicle and thus not only acts as the
beating apparatus for heating the compartment but also as a foot warner for the use
of the occupants the top surface being roughened for instance as illustrated by
the diaper pattern in the plan view Fig. 4 to prevent slipping in walking across
the same.
On the branch pipe (e) a suitable stop cock or valve (h) is fitted, the handle (i) of
which is conveniently disposed as illustrated for the passengers to actuate the same so
as to open and close the communication at will.
And thus each compartment is capable of being heated and controlled independently
of the adjoining compartments of the same carriage.
And in order to blow off the air in the first instance I provide a blow off cock (j) at
each end of the casing (f) and which also may be arranged to be operated from the

page_text: inside of the vehicle if found desirable. A draw off cock (k) is also fixed at either
end of the carriage for withdrawing any condensed water accumulating in the length
of the heating pipe (a) and for emptying such pipe in case of hot water being used as
the heating medium.
In Fig. 5 I illustrate a side view and in Fig. 6 a plan view of a tram-car shewing
the application thereto of my improved heating apparatus.
In both views (a) is a vertical steam boiler conveniently arranged at the left side of
the driver and which is shewn heated by the flames of a number of lamp wicks (bb)
supplied with hydrocarbon or other suitable oil from a reservoir (c) and controlled
as to their height by the usual adjusting spindles (d).
The waste heat and products of combustion from these burners are by preference
carried up through a central flue (e) and thereby assist the heating operation. The
top of this boiler is further enclosed with a casing (f) fitted with a door (9) and
thus constitutes a heating chamber or oven for warming the driver's and conductor's
meals.
Rising from the top or steam space of this boiler is a heating pipe (h) which is first
carried round one side of the roof of the tram-car then crosses to the other side, where
it is continued in the opposite direction until the opposite corner is reached. Here
the pipe descends to the floor of the tram-car and is continued along both sides thereof
in a similar manner to that in the roof and finally opens into a drip box (i). This
pipe (h) is kept supplied with steam at a low pressure from the boiler (a) and thus it
performs the function of heating the tram-car."
In case I desire to use the steam pipe (h) as a foot warmer I cast or otherwise
form the upper surface thereof flat and so as to present a broad surface and at that
part where such pipe dips down to cross the entrance of the tram-car, I arrange a
heating casing () upon which the conductor can conveniently stand. In some cases
the heating pipe is only carried round the floor of the tram-car.
The boiler is supplied with a water guage (k) water feed pipe (1) and draw off
cock (m) and the usual fittings and the drip box with a draw off tap (n) for the
periodical removal of any condensed water.
Although I have only hereinbefore described and illustrated the application of steam
as the heating medium employed it will be apparent that hot water or hot air could
also be used with my improved system of heating railway carriages tram-cars or other
vehicles. I wish it also to be understood that I do not confine myself in the case of
a tram-car to the use of a steam boiler heated by lamp wicks as it will be obvious that
compressed gas or other form of furnace might be substituted.
Having thus particularly described and ascertained the nature of my invention and
in what manner the same is to be performed I declare that what I claim is -—
1st. The improved combination and arrangement of heating apparatus for railway
carriages substantially as hereinbefore described and illustrated on the accompanying
drawing.
2nd. The application of a heating chamber to each compartment of a railway
carriage fitted and operated substantially as and for the purpose hereinbefore described
and illustrated upon the accompanying drawing.
3rd. The improved combination and arrangement of heating apparatus for tram-cars
and other vehicles substantially as hereinbefore described and illustrated on the
accompanying drawing.
