I, JAMES DOUGLAS WATSON of 162 Renfield Street, Glasgow, in the County of
Lanark, North Britain, Manufacturing Chemist and Druggist do hereby declare the
nature of this invention to be as follows:-
This Invention which relates to improvements in ventilators is especially applicable
to the ventilation of compartments of railway carriages, steam and sailing vessels, and
other such enclosed spaces. The said Invention consists of a cylindrical casing the
lower end of which is partially closed by a perforated concave cap or plate and which
casing is secured in position at the top of the compartment by means of a flange
encircling the said casing. At the interior of the before-mentioned casing is provided
an inwardly-projecting flange or ring in the central opening of which a vane-wheel is
capable of rotating horizontally the said central opening being of diameter only
sufficient to enable the vane-wheel to rotate without contact with the surrounding
edge thereof. This vane-wheel is, or may be constructed with an outer band of metal
to which the outer ends of the inclined or helical vanes are secured, and the said
wheel is securel upon a vertical spindle the lower end of which is preferably supported,
in and upon a small piece of sheet glass which is carried by a bracket secured to the
sides of the casing. The upper end of the spindle may be similarly supported by a
piece of glass drilled for the purpose or it may be retained in a vertical position by
means of a metal bracket or its equivalent.
To prevent the rain entering the beforementioned ventilator a cover is provided
and the said cover is constructed with two, three, four or more downwardly-projecting
pins which enter holes formed in standards which are secured to the flange encircling
the enclosing casing, or the said cover may be supported by any other equivalent
means.

page_text: I, JAMES DOUGLAS WATSON of 162 Renfield Street, Glasgow, in the County of
Lanark, North Britain, Manufacturing Chemist and Druggist, 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 improvements in ventilators is especially applicable
to the ventilation of compartments of railway carriages, steam, and sailing vessels and
other such enclosed spaces. The said Invention consists of a cylindrical casing the
lower end of which is partially closed by a perforated concave cap or plate and which
casing is secured in position at the top of the compartment by means of a flange
encircling the said casing. At the interior of the beforementioned casing is provided
an inwardly projecting flange or ring in the central opening of which a vane wheel is
capable of rotating horizontally the said central opening being of diameter only
sufficient to enable the vane wheel to rotate without contact with the surrounding
edge thereof. This vane wheel is or may be constructed with an outer band of metal
to which the outer ends of the inclined or helical vanes are secured and the said wheel
is secured upon a vertical spindle, the lower end of which is preferably supported in
and upon a small piece of sheet or crystal glass, which is carried by a bracket secured
to the sides of the casing. The upper end of the spindle may be similarly supported
by a piece of glass, drilled for the purpose, or it may be retained in a vertical position
by means of a metal bracket or its equivalent.
To prevent the rain entering the before-mentioned ventilator a cover is provided
which may be constructed with two, three, four or more downwardly projecting pins
which enter holes formed in standards which are secured to the flange encircling the
enclosing casing, or the said cover may be supported or carried by other equivalent
means such as, by 2, 3 or more bent wires projecting downwards and inwards, the
upper ends of said wires being fixed to the cover, and the lower ends secured to a belt
which exactly fits the external circumference of the said casing.
In order that my said Invention may be properly understood, and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed.
Figures 1 and 2, illustrate an arrangement according to my Invention for ventilating
the compartments of railway carriages, steam and sailing vessels, and other such
enclosed spaces, Figure 1 representing a vertical section of the ventilator and cover,
and Figure 2 being a plan of the same with the cover removed.
According to the arrangement illustrated in the said Figures, my Invention consists
of a cylindrical casing A, the lower end of which is partially closed by a perforated
concave cap or plate B, and which casing A, is secured in position at the top of the
compartment by means of a flange C, encircling the said casing A. At the interior of
the beforementioned casing A, is provided an inwardly projecting flange or ring D,
above the central opening of which a vane wheel E is capable of rotating horizontally,
the said central opening being slightly larger in diameter than the vane-wheel E.

page_text: This vane wheel E is constructed with an outer band of metal F, to which the outer
ends of the inclined or helical vanes G are secured and the said wheel E is secured
upon a vertical spindle H, the lower end of which is preferably supported in and upon
a small piece of sheet or crystal glass I, which is carried by a bracket K, secured to
the inner flange D, of the casing A. The upper end of the spindle H is similarly
supported by a piece of glass L, drilled for the purpose, and carried by a bracket M
which is secured to the side of the casing A.
To prevent the rain entering the beforementioned ventilator a cover N, is provided
and the said cover N, may be constructed with two three, four or more bent wires O,
which project downwards and inwards as shewn at Figure 1, the upper ends of the
bent wires O, being secured to the cover N and the lower ends secured to the belt P,
which exactly fits the external circumference of the casing A.
The heated or foul air accumulated in the compartments of railway carringes or
other enclosed spaces ascends and enters the ventilator in the direction indicated by
the arrow shewn in Figure 1, causing the vane wheel E to revolve drawing and forcing
the foul air to the outside of the 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
The general arrangement and combination of parts constituting the improvements
in ventilators substantially as, and operating in the manner hereinbefore described,
with reference to the annexed drawings,
