Improvements in Apparatus for Warming Railway Carriages.
JAMES CHEETHAM Riversdale, Stanton Avenue West Didsbury, Manchester
Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the method and means for warming
railway carriages, where steam or hot water is caused to circulate through pipes,
in the interior of the carriages, and consists in a combination of radiating plates
made of copper or other metal with the iron piping, and so connected or fixed to
the said warming pipes, inside the compartments of the carriages for the purpose
of increasing the heating surface, the metal plates being made in shape, to fit
tightly on the iron pipes, and by close contact with them while hot, will extract
the heat therefrom, and radiate it off into the compartment.
For this purpose I provide or fix lengthwise or transversely on the exterior of
the pipes, one or more plates or webs, of good conducting metal such as copper,
which I place in suitable, and convenient positions, so that the heat from the pipe
being readily conducted throughout the said plates or webs a greatly increased
heating surface is presented to the air in the carriage.

I JAMES CHEETHAM of Riversdale Stanton Avenue West Didsbury Manchester
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 :-
My invention consists in improvements in the method and means for warning
railway carriages when and where steam or hot water circulates through pipes
placed in the interior of the carriages by fixing upon and combining with such
circulating pipes radiators made of metal plates of the form shewn and attached
thereto in the way and according to the method described for the purpose of very
much increasing the heating surface of the metal and so to throw off greater heat
into the compartments of the carriages.
For this purpose I provide and fix lengthwise or transversely on to the circulating
pipes one or more plates or radiators of good heat conducting metal which I place
in suitable and convenient positions inside the carriages so that the heat from the
pipes being readily conducted throughout the said plates or radiators a greatly
increased heating surface is presented to the air in the carriage.

fitted to the pipes in a convenient position at each corner of the compartment
underneath the seats.
Sheet 2 Figures 3 and 4 shew sections of the radiating plates and how fixed or
attached to the circulating pipes Figure 5 being an elevation of the same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In combination with apparatus for warming railway carriages radiating plates
made of metal of the shape and form described and illustrated in Figures 3, 4 and 5
so as to fit or slide upon the circulating pipes substantially as described.
The combination of these radiating plates with the circulation pipes in the
manner described and shewn for the purpose of increasing the surface of the metal
to throw off a greater amount of heat into the carriage from the steam or hot
water passing through the pipes.
Dated this 26th day of September 1895.
