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 relates to improvements in ventilators and consists of a box which
is preferably of cast iron and formed in two parts jointed and bolted or otherwise
secured together. The underside of this box is perforated, and thus constitutes the
inlet to the ventilator, and one of the vertical sides thereof is formed with an opening
and pipe which together constitute the outlet of the ventilator. In this outlet pipe at
or near the end thereof nearest the beforementioned box, a vane-wheel is supported in
bearings co-axially within the outlet pipe, while at or near the outer end of the said
outlet pipe a fan like wheel is supported in bearings so that its axis of rotation lies
diametrically accross the said outlet pipe. The first-mentioned wheel, that is to say,
the vane-wheel is of similar or approximately similar construction to those often used
in anemometers, that is to say, its consist of a circular band or short light metal
cylinder with the vanes arranged radially within it on lines oblique to the axis of
rotation of the said wheel. The beforementioned fan-like wheel is constructed with a
series of radial blades, and in order to prevent any wind blowing into the ventilator a
catch is so arranged within the outlet pipe thereof relatively with the said fan-like
wheel as to admit of its rotating in one direction only.
The hereinbefore described ventilator is arranged to be placed between the ceiling
of the room or other apartment to be ventilated and the floor of the room or other
apartment next above it. When so arranged it is preferred to locate the said ventilator
above the gasalier, when such is employed, under which circumstances the before-
mentioned box is provided with a bracket or its equivalent, of sufficient strength to
support the weight of the said gasalier, the gas supply pipe to which passes in at one
of the vertical sides of the box, and out through the perforated underside thereof, the
box itself being secured to and between the floor joists in any suitable manner. The
beforementioned outlet pipe is connected to one communicating with the outside of
the building.

Improvements in Ventilators.
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, consists of a box
which is preferably made of cast iron, and formed in two parts, jointed and bolted,
or otherwise secured together. The underside of this box is perforated which
constitutes the inlet to the ventilator, whilst one of the vertical sides thereof is formed
with an opening and pipe which together constitute the outlet of the ventilator. In
this outlet pipe at or near the end thereof, nearest the beforementioned box a vane
wheel is supported in bearings co-axially within the outlet pipe, while at or near
the outer end of the said outlet pipe a fan-like wheel is supported in bearings so that
its axis of rotation lies diametrically across the said outlet pipe. The first mentioned
wheel, that is to say, the vane wheel, is of similar or approximately similar construction
to those often used in anemometers, that is to say, it consists of a circular band or
short light metal cylinder, with the vanes arranged radially within it on lines oblique
to the axis of rotation of the said wheel. The beforementioned fan-like wheel is
constructed with a series of radial blades, an in order to prevent any wind blowing
into the ventilator, a catch is so arranged within the outlet pipe thereof, relatively
with the said fan-like wheel, as to admit of its rotating in one direction only.
The hereinbefore described ventilator is arranged to be placed between the ceiling
of the room or other apartment to be ventilated and the floor of the room or other
apartment next above it. When so arranged it is preferred to locate the said ventilator
above the gasalier, when such is employed, under which circumstances the before-
mentioned box is provided, with a bracket or its equivalent of strength sufficient to
support the weight of the said gasalier, the gas supply pipe to which passes in at one
of the vertical sides of the box, and out through the perforated underside thereof, the
box itself being secured to and between the floor joists in any suitable manner.
beforementioned outlet pipe is connected to one communicating with the outside
of the building.
The
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.
Figure 1, is a vertical section of a ventilator constructed according to and
constituting my present Invention.
Figure 2 is a plan of the same with the upper part of the casing or box removed,
and Figure 3, is a front elevation of the vane wheel.
The ventilator constructed in accordance with this Invention consists of a box A,
which is preferably of cast iron and formed in two parts jointed and bolted together
at the flanges B. The underside C of this box A, is perforated as shown at Figure 2,
and thus constitutes the inlet to the ventilator, whilst one of the vertical sides thereof

page_text: is formed with an opening and pipe D, which together constitute the outlet of the
ventilator. In this outlet pipe D, at or near the end thereof nearest the before-
mentioned box A, a vane wheel E, is supported in bearings F F, co-axially within the
outlet pipe D, while at or near the outer end of the said outlet pipe D a fan like
wheel G is supported in bearings H H, so that its axis of rotation lies diametrically
across the said outlet pipe D. The vane-wheel E consists of a circular band or short
light metal cylinder I, with the vanes J, arranged radially within it on lines oblique
to the axis of rotation of the said wheel E. The beforementioned fan like wheel G
is constructed with a series of four or more radial blades, and in order to prevent
any wind blowing into the ventilator a catch K is so arranged within the outlet
pipe D thereof relatively with the said fan like wheel G as to admit of its rotating
in one direction only, thus preventing any back current or draught.
The hereinbefore described ventilator is arranged to be placed between the ceiling
of the room or other apartment to be ventilated, and the floor of the room or other
apartinent next above it. When so arranged it is preferred to locate the said ventilator
above the gasalier, when such is employed, under which circumstances the before-
mentioned box A, is provided with a bracket, or the bottom C is made of strength
sufficient to support the weight of the said gasalier, the gas supply pipe to which
passes in either at one of the vertical sides of the box A, or through the hole L, at
the top thereof, and out through the perforated underside at M. The heated air,
Gas, or smoke, which may accumulate in the room or other enclosed space ascends
towards the ceiling and enters the ventilator, causing the vane wheel E and fan
wheel F, to revolve, and thus still farther increase the current of air in that direction,
and forces it onwards through the outlet pipe D, to the outside of the building.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be preformed, I declare that what I claim is :-
:-
First The general arrangement and combination of parts constituting the
improvements in ventilators, substantially as and operating in the manner herein-
before described with reference to the accompanying drawings.
Second The improvements in ventilators consisting of the arrangement of the
fan like wheel G, at one end of the pipe D, and in relation to the vane wheel E,
substantially as and operating in the manner and for the purposes hereinbefore set
forth.
Third The catch K within the outlet pipo D substantially as and for the purposes
herein before set forth with reference to the annexed drawings.
