PROVISIONAL SPECIFICATION.
New or Improved Apparatus for Heating or Ventilating Railway or
other Carriages.
İ, ROBERT BELL of 29 Lynedoch Street, Glasgow, in the County of Lanark
North Britain, Doctor of Medicine, and Fellow of the Faculty of Physicians and
Surgeons of Glasgow do hereby declare the nature of this invention to be as
follows:
This Invention which relates to a new or Improved apparatus for heating or
ventilating railway or other carriages, consists of a tubular spiral coil, communicating
with an inlet or suction pipe and a discharge pipe, the said coil and piping being
made of iron or other suitable metal. The inlet or suction pipe, which is provided
at its outer end with a Bell-mouth for the admission of air, is connected to the coil
at its base, or to that revolution which has the greatest radius, whilst the discharge
pipe which communicates the hot air to the carriage, is connected to the coil at its
apex. A cock is placed at a convenient part of the inlet pipe to regulate the supply
of air. When not in use as a beating apparatus, the invention can be employed as a
Ventilator.
The spiral coil is intended to be placed or fixed immediately above the usual gas
light, and preferably covered with asbestos or other incombustible material, so that
the gas light striking on the coil and asbestos, creates a heated air which is com-
municated to the carriage as herebefore described.

COMPLETE SPECIFICATION.
New or Improved Apparatus for Heating or Ventilating Railway or
other Carriages.
I, ROBERT BELL of 29 Lynedoch Street; Glasgow, in the County of Lanark
North Britain, Doctor of Medicine and Fellow of the Faculty of Physicians and
Surgeons, 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 which relates to new or improved apparatus for heating or ventilating
railway or other carriages consists in the employment of a tubular spiral coil com-
municating with an inlet or suction pipe, and a discharge pipe, the said coil and
piping being made of iron or other suitable metal.
The apparatus is so arranged that the coil is placed or fixed by suitable means
immediately above the usual gas light and which may be covered with asbestos or
other incombustible material. The inlet pipe which is provided at its outer extremity
with a bell-mouth capable of being adjusted and turned by the force of the wind is
connected at its inner end to the base of the coil whilst the discharge pipe is con-
nected to the coil at its apex. The supply of air to the apparatus is regulated by
means of a suitable cock placed at a convenient part of the inlet pipe.
When not in use as a heating apparatus the invention may be used as a ventilator.
by adjusting the inlet pipe and cock for regulating the supply of air.
In order that my invention may be more easily understood and readily carried
into effect, I will now proceed to describe the same with reference to the accom-
panying drawings. Figure 1, sheet 1, is an elevation of my apparatus, and
Figure 2, sheet 2 an elevation of one method of employing my apparatus to a
railway carriage.

page_text: A, is a tubular spiral coil of iron or other metal piping, which may be covered in
any suitable way by asbestos or other incombustible material, and placed or fixed by
suitable means above the usual gas light B, of the carriage. The base a, of the coil
or that revolution which has the greatest radius is connected to the inlet pipe C, of
iron or other metal which is provided at its outer end with an adjustable bell-mouth D,
and a cock E, for regulating the supply of air. The apex a', of the coil is connected
to the iron or other suitable metal discharge pipe E, which may be led in any suitable
way to any desired part of the carriage, but preferably as shown in Figure 2, that
is, led along the roof, thence down the wall or partition and out near the floor and
under the seat, as shewn at f.
This arrangement being such that on the cool air passing in at the bell-mouth it
then proceeds through the coil where it is heated by means of the gas flame, after
which it discharges into the carriage near the floor, where it becomes inixed with the
air in the carriage and tends to heat it
up.
If desired when my apparatus is not in use as a heating apparatus it may be used
as a ventilator, the ventilation being regulated by means of the.cock E.
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 1.
claim is.
In apparatus for heating or ventilating railway or other carriages the employment
and arrangement of a tubular spiral coil A, inlet pipe C, bell-mouth D, regulating
cock E, and discharge pipe F,.all substantially as and for the purposes hereicbefore
described and shown in the accompanying drawings.
