JOHN MILNES Commission Agent 4, Manor Street, Kings Mill Lane Huddersfield
in the County of Yorkshire, do hereby declare the nature of this invention to be as
follows:
An apparatus for warming railway carriages by means of the roof lamps, that are
used to illuminate, the said carriages, utilising the heated air that is given off, from the
gas or oil in the lamps.
This apparatus consists of two circular cases, an inner and an outer case, the inner
is made much longer than the outer case, the space at the bottom and between the two
cases is closed up and joined together, on a level with each other, the space at the top,
and between the two cases is closed up and joined together by means of a dish-shaped
cover, which reaches up, a certain distance on to the inner case.
-
The space between the two cases, is now completely closed in, this space or
chamber is intended for the warm air to accumulate.
The portion of the inner case which projects above the outer case, I will now call
the cap of the lamp-case.-round the sides of the cap of the lamp-case, I place venti-
lation holes or slits, I also cover the top of the lamp-case, which is the funnel or inner
circular case, with a covering, which covering is punctured with a quantity of holes
to allow the smoke to pass out.-the centre portion of this covering, I make in the
shape of a lid, it shall lift up by means of a hinge, this opening is intended for lighting
the gas or oil in the lamp, this is to avoid the lifting up or opening of the apparatus
or of undoing any of the tubes of the apparatus, which apparatus fits into the rim
that holds the present lamp-glass and lamp.-The apparatus can be fixed to the rim-
holder and lifts off or on by means of an hinge, and is fastened down by means of a
catch.
The inner circular case will act as a funnel for the smoke and foul vapours to
pass away.

page_text: At the upper portion of the dish-shaped cover, I place one or more funnel-shaped
mouthpieces for the warm air to escape, from the warm air chamber, which is between
the inner and outer case,-to these funnel-shape mouthpieces can be fixed tubes or
pipes which connect the case with the inside of the carriage.
The outer case is provided with a number of draught slits or holes, made near
the bottom of the outside case, but placed so, that they are above the roof of the
carriage, as an inlet for cold air, the momentum of the train, which will act upon
the draught holes or slits, at the bottom of the outside case, is sufficient to drive
the warm air into the pipes or tubes and thence into the carriage.

page_text: COMPLETE SPECIFICATION.
An Apparatus for Warming Railway Carriages and other
Conveyances.
JOHN MILNES Commission Agent 4, Manor Street Kings Mill Lane, Huddersfield
in the county of Yorkshire, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
1. This simple invention, is intended to be used in connection with the gas and
oil roof lamps, that are now in use to illuminate the said carriages, utilising the
heated air that is given off, from the gas or oil in the lamps..
2. This apparatus consists of two circular cases, an inner and an outer case, the
inner is made much longer than the outer case, the space at the bottom and between
the two cases is closed up and joined together on a level with each other, the space
at the top and between the two cases is closed up and joined together by means of a
dish-shaped cover which reaches up a certain distance on to the inner case, The
space between the two cases is now completely closed in, this apace or chamber is
intended for the warm air to accumulate.
3. The portion of the inner case which projects above the outer case, I will now
call the cap of the lamp-case,-round the sides of the cap of the lamp-case, I place
ventilation slits or boles, I also cover the top of the lamp-case which is the funnel
or inner circular case, with a covering, which covering is punctured with a quantity
of holes to allow the smoke to pass out, the centre portion of this covering, I
make in the shape of a lid, it shall lift up by means of an hinge, this opening is
intended for lighting the gas or oil in the lamp-this is to avoid the lifting up
or opening of the apparatus or of undoing any of the tubes of the apparatus,
which apparatus fits into the rim that holds the present lampglass and lamp,-the
apparatus can be fixed to the rimholder and lifts off and on by means of an hinge
and is fastened down by means of a catch.
4. The inner circular case will act as a funnel for the smoke and foul vapours
to pass away.
5. At the upper portion of the dish-shaped cover I place one or more funnel-
shaped mouthpieces for the warm air to escape from the warm air chamber, which
is between the inner and outer cases, to these funnel shaped mouthpieces, can be
affixed tubes or pipes, which connect the case with the inside of the carriage.
6. The outer case is provided with a number of draught holes or slits, made
near the bottom of the outside case, but placed so, that they are above the roof
of the carriage, as an inlet for cold air, the momentum of the train, which will
act upon the draught holes or slits at the bottom of the outside case, is sufficient
to drive the warm air into the pipes or tubes and thence into the carriage.
7. 1 place a sliding shutter, which covers a portion of the draught holes or slits,
which are situated near the bottom of the outside case, this shutter can be regulated
as required.

page_text: 8. For using one or more pipes or tubes, which can either remain loose or be
fixtures, which pipes or tubes connect the mouthpieces and case with the inside of
the carriage. The pipes or tubes entering the carriage through an opening on the
roof or sides of carriage or so placed as to meet the requirements of the different
lamps and carriages-in the inside of the carriage is placed a shutter-box with a
ventilating-shutter, in which is placed the pipes or tubes, the passengers can
regulate the warmth that is desired.
In order to explain my simple invention, if needs be more clearly, I enclose
along with this a drawing of the apparatus as attached to a railway roof lamp.-
The inner circular case in figure 1, is marked A on diagram, which is a vertical
section of the apparatus and roof lamp, the space between the inner circular and
outer case is marked B. which space or chamber is intended for the warm air to
accumulate and then pass out by the funnel shaped-mouthpiece marked C. along
the pipe or tube marked D. into the carriage, the outside case is provided with a
number of holes or slits marked E, as inlets for cold air, the lid on the top of apparatus
is marked F.-The shutter is marked G.
Figure 2, represents the pipe or tube.
Figure 3, represents the cases in circular form.
This invention can be used with reference to ordinary road or tramway conveyances.-
either from the roof or sides of carriage.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
1. The inner circular case.
11. The draught holes or slits near the bottom of outside case with shutter attached
to the same.
III. The lid on top of apparatus, which is used for lighting the gas or oil in the
lamps.
IV. The warm air chamber as described in specification, which is the space between
the two cases.
