1, JAMES MEEK, of 9 Park Road South, Birkenhead, in the County of Chester,
Marine Superintendent, do hereby declare the nature of my said invention to be as
follows:-
The object of my Invention is to so construct a ventilator for ships that while
leaving space for the free ingress, or egress of air such space is protected from the
ingress of water caused by seas breaking over the mouth of the ventilator, or
otherwise.
Ventilators as at present used on board ship are most commonly open mouthed
cowls turning on the top of a pipe or duct leading to the part to be ventilated.
Downcast ventilators being turned with their mouths to the wind, and the upcast
ventilators being turned with their mouths from the wind. In bad weather at sea
the cowls are generally unshipped and the top of the ventilator pipes are covered
over, so that there is no danger of water passing down the ventilator, which would be
the case if the cowls were left on, the ventilator is thus inoperative during such bad
weather.
Now my Invention consists in providing a means to prevent water entering the
cowl and ventilator and at the same time not to stop, or block the air passage. To
this end I provide the mouth of the cowl with an internal fitting having a gutter, or
waterway, and a central passage, or hole, which passage has a sectional area equal to,
or greater than the sectional area of the ventilator pipe. The upper portion of the
periphery of this central passage is provided with a lip. Surrounding the central
passage I provide a
section bonnet, which when in
position leaves an annular
passage between itself and the rim of the gutter or waterway. This bonnet is also
provided with a central opening protected by a second bonnet of ▷ section. This
central opening may be further protected by an internal shield. The whole of the
parts are connected together by brackets, or feathers and are made to fit into the cowl
mouth of a ships ventilator, or they can be made to fit on to the doors of deck houses,
cabins and like places which are exposed to the action of the sea breaking on them,

page_text: In application the device according to my Invention may be detachable from the
ventilator cowl and only applied in bad weather, or it may be a permanent part of the
ventilator cowl. Water when striking the ventilator cowl with my appliance fitted
thereto, falls into the gutter, or waterway of the internal fitting and is thus carried
off, the bonnets protecting the centre of the cowl mouth, at the same time the
construction of the gutter, or waterway and the bonnets and their combination are
such as to allow for a free passage for air, equal to about seventy five per cent of the
capacity of the cowl mouth and about equal, or more than equal to the sectional area
of the ventilator pipe.

I, JAMES MEEK, of 9 Park Road South, Birkenhead, in the County of Chester,
Marine Superintendant, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my Invention is to so construct ventilators of the disc, or face type
for ships that while leaving space for the free ingress, or egress of air such space is
protected from the ingress of water caused by seas breaking over the mouth of the
ventilator, or otherwise.
Ventilators of the disc, or face type as at present used on board ship are most
commonly open mouthed cowls free to turn on the top of a pipe, or duct leading to
the part to be ventilated; "downcast" ventilators being turned with their mouths to
the wind and the upcast ventilators being turned with their mouths from the wind.
In bad weather at sea the cowls are generally unshipped and the top of the Ventilator
pipes are covered over so that there is no danger of water passing down the ventilator,
which would be case if the cowls were left on; the ventilator is thus inoperative during
such bad weather.
Now my Invention consists in providing a means to prevent water passing the
ventilator and at the same time not to stop, or block the air passage. To this end I
provide the ventilator with an internal annular fitting, constituting a gutter, or
waterway and having a central passage or hole.
The upper portion of the periphery of this central passage may be provided with a
lip. Surrounding the central passage I provide a bonnet, which when in position
leaves an annular passage between itself and the rim of the gutter, or waterway.
This bonnet is preferably also provided with a central opening protected by a second
bonnet. This central opening may be further protected by an internal shield. The
whole of the parts are connected together by brackets, or feathers and are made to
fit into the cowl mouth of a ships ventilator, or they can be made to fit into deck
houses, cabins and like places which are exposed to the action of the sea breaking
over them.
The following is a description of examples of my Invention (in its preferred forms)
sufficient to enable any person skilled in the art to which it belongs to carry the same
into practice, reference being had to the annexed sheets of Drawings and to the letters
and figures of reference marked thereon, like letters and figures being used to denote
the same, or corresponding parts throughout the Drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional elevation of a ventilator cowl with my improvements applied
thereto.
Figure 2 is a sectional elevation of a ventilator cowl shown with a modification of
my improvements applied thereto.
Figure 3 is an elevation of a ventilator according to my Invention as applied to
deck houses, cabins and like places.
According to my Invention, I provide the mouth of the ventilator cowl a with an
internal fitting b¹ (a convenient form of which is shown at Figure 1 and a modification

page_text: of which is shown at Figure 2) which fitting constitutes a circular gutter, or
waterway b (the outer rim of the fitting is made to correspond with the mouth
of the cowl) and it may be a fixture therein, or detacheable, the waterway b¹
extending some distance inside the cowl mouth and having a mouth, or central
passage b².
The upper portion of the periphery of the central passage may as
shown at Figure 1 be provided with a lip c. In this example surrounding the centra
passage 6 of the fitting b¹ I provide the bonnet d which is so located as to leave
annular passages e between itself and the rim of the mouth 62 of the gutter, or
waterway 6. This bonnet d is also provided with a central opening protected by
a second bonnet g and the opening f may be further protected by an internal shield h.
The whole of the parts namely the fitting and bonnets d and g are connected
together by brackets, or feathers i.
In the modification shown at Figure 2 the fitting 61 is set up so as to touch the
top of the cowl a at a. a³ is a plate reaching from the fitting to the shell of the
cowl a provided to prevent the air eddying between the fitting b and the shell of the
cowl a.
63 is a shield which is placed inside the opening 2 of the fitting b¹ to throw
any water which may enter it into the waterway 6. The shape of the bonnet d in
this example is different from the bonnet shown in Figure 1, and the bonnet
is
dispensed with and there is provided a shield h placed inside of the opening f, and
outside and over the bonnet d'there are provided two additional bonnets & which act
to break the force of the water when striking the ventilator.
In Figure 3 A represents in elevation the side of a deck house, or like place,
provided with a ventilator having fittings as above described in reference to Figure 2.
In application the guard devices, or fittings b' and the parts connected therewith
according to my Invention may be detacheable from the ventilator, or cowl and only
applied in bad weather; or they may be a permanent part of the ventilator cowl, or
they may constitute the ventilator. Water when striking the ventilator with my
appliance fitted thereto falls into the gutter, or waterway of the internal fitting b¹ and
runs out at the bottom and is prevented from getting past, or through the opening b²
by means of the bonnet which protects the centre of the ventilator mouth, at the same
time the construction of the gutter, or waterway 6' and the bonnets and shields and
their combination are such as to allow for a free passage for air equal to about ninety
per cent of the capacity of the ventilator mouth, and in the case of cowl ventilators
the free area is about equal, or more than equal to the sectional area of the ventilator
pipe a. The arrows in the Drawings indicate the passage of the air through the
ventilator.
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. In ships ventilators of the disc, or face type the means substantially set forth for
preventing water passing therethrough which consists essentially of an annular fitting,
or waterway (such as 6) having a central opening (such as 62) provided with a
protecting bonnet, or bonnets.
2. In ships ventilators of the disc or face type the combination of an annular fitting,
or waterway bonnet d and shield h, the said waterway b¹ and bonnet d having
central passages b² and f.
3. The construction of ventilator substantially as set forth with reference to Figure 1
of the Drawings hereto annexed.
4. The construction of ventilator substantially as set forth with reference to Figure 2
of the Drawings hereto annexed.
