PROVISIONAL SPECIFICATION.
Improvements in Ventilators used on Board Ship, Railway Carriages,
or in other places.
1, CHARLES GANNAWAY of 6 Robertson Street, Glasgow, in the County of
Lanark, North Britain, Steamship Inspector do hereby declare the nature of this
invention to be as follows :—
This invention, which relates to improvements in ventilators used on board ship,
railway carriages, or in other places has in the first place for its object whilst
insuring perfect ventilation to prevent the water or rain storms or that due to the
waves or spray of the sea from passing down into the ship or other space or spaces
or apartments to which such ventilators are applied. My invention consists of a
shield which is placed over the mouth of the ventilator, being preferably attached
thereto by a hinged joint so that it can be instantly applied to the ventilator
mouth or lowered or raised therefrom on a hinge after a storm has passed. The
improvements consist of a series of curved nozzles which are fixed into or form part
of a plate constituting the front of the shield and whose inner portions curve down-
wards in the direction of the ventilator shaft at the lower part of the ventilator
mouth. Where the improvements are applied a chamber or pocket is placed, into
which the rain, or storm water which may pass through the nozzles during al
storm is caught. This chamber or pocket is provided with doors at each side
through which such rain water escapes, these being placed at such an angle that
they keep practically shut by the action of gravity during the heeling over or
rolling of the ship. In lieu of placing these doors at the side of the chamber or
pocket, a door may be placed in the front thereof or both at the side and front.
When the improvements are applied to windows or other places through which
light as well as ventilation is required to pass, the nozzles may be made of glass,
talc, or other transparent material and in which case they may be fixed or
suspended.

COMPLETE SPECIFICATION.
Improvements in Ventilators used on Board Ship, Railway Carriages,
or in other places.
1, CHARLES GANNAWAY, of 6 Robertson Street, Glasgow, in the County of
Lanark, North Britain, Steamship Inspector, 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 used on board ship,
railway carriages, or in other places, has for its object, whilst insuring perfect
ventilation, to prevent the water or rain storms or that due to the waves or spray of
the sea from passing down into the ship or other space or spaces or apartments to
which such ventilators are applied. My invention consists of a shield which is
placed over the mouth of the ventilator, being preferably attached thereto by a
hinged joint so that it can be instantly applied to the ventilator mouth, or
lowered or raised therefrom on a hinge after a storm has passed. The improve-
ments consist of a series of curved nozzles which are fixed into or form part
of a plate constituting the front of the shield and whose inner portions curve
-

page_text: towards the ventilator shaft at the lower part of the ventilator mouth. Where
the improvements are applied a chamber or pocket is placed, into which the
rain, or storm water which may pass through the nozzles during a storm is
caught. This chamber or pocket is provided with doors at each side through
which such rain water escapes, these being placed at such an angle that they
keep practically shut by the action of gravity during the heeling over or
rolling of the ship. In lien of placing these doors at the side of the chamber
or pocket, a door may be placed in the front thereof, or both at the side
and front.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended an explanatory sheet of drawings, in the
several figures of which corresponding parts are marked with the same letters
of reference.
Figure 1 is a front elevation showing one modification of my improvements.
Figure 2 is a section thereof.
Figure 3 is a front elevation of another modification of my improvements.
Figure 4 is a section thereof.
A is the shield which is placed over the mouth of the ventilator B. This shield A
is preferably attached to the ventilator by a hinged joint C, so that it can be
readily applied to the ventilator mouth or lowered therefrom after a storm has
ceased. D are the curved nozzles or sub-divisions which are fixed into or form part
of the plate E forming the front part of the shield A. Any rain or storm water
which may pass through the nozzles D during a storm falls into chamber or pocket F
provided for the purpose. This pocket F has doors G at each side through which
such rain escapes, these being placed at such an angle that they keep practically
shut by the action of gravity during the heeling over or rolling of the ship, as
already described.
In place of having the spaces forming the nozzles subdivided as shown in Figures 1
and 2, I may have these continuous as shown at H Figures 3 and 4. The other
parts being in every way similar to those described and shown with reference to
Figures 1 and 2, need not be herein further described.
When the improvements are applied to windows or other places through which
light as well as ventilation is required to pass, the nozzles may be made of glass,
talc, or other transparent material, and in which case they may be fixed or
suspended.
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 :-
The improvements in ventilators used on board ship, railway carriages, or in
other places, substantially as and for the purposes hereinbefore described and shown
on the accompanying sheet of drawings.
