PROVISIONAL SPECIFICATION.
Improvements in and relating to Ships' Side Lights and Ventilators
I, EDMUND SILARER, of The Fairfield Shipbuilding and Engineering Company,
Limited, Fairfield Works, Govan, in the County of Lanark, Shipbuilder, do hereby
declare the nature of my invention to be as follows;-
-
This invention has reference to and comprises improvements in and relating to
ships' side lights and ventilators for oabins and the like by which these are used
in combination and means adopted for preventing the entry of water within the
vessel, when at any time the ventiluting opening is temporarily immersed and for
closing same when the sea is heavy.
In carrying into practice the improvements of this invention the frame of the
circular or otherwise shaped side light by which it is secured to the ships' side is
extended upwards and has another opening for ventilating purposes formed
therein which is preferably fitted or covered with a grating of metal fretwork or
the like but is otherwiso permanently open. On the inside of the vessel and
secured to the frame is a casing forming an air inlet or duct which is fitted with a
float valve and a closing valve constructed and arranged under one modification all
as follows:--Within the cusing the air passage is formed of a cylindrical shape
with an open bottom and an inwardly projecting flange around its lower edge
while the upper part is formed as a hood so as to allow the air to flow out in a
horizontal direotion. At the top of the cylindrical part another inwardly project-
ing flauge is formed and indiarubber or other packing is inserted within au
annular recess formed in the lower face of the flange. A float valve, preferably a
hollow metal float works within the cylindrical part and is guided and supported
by stepped feathers secured or formed therein and by a spindle working through
a bridge piece or perforated diaphragm formed or secured above it. The top
edge of this float valve is tormed as a ridge to make a fluid tight joint with the
annular packing when pressed into contact by the float valve rising when water
enters within the casing and so prevents it passing into the cabin or vessel.
The opening at the top of the casing admitting the air to the interior of cabin
or vessel is formed circular and has a flange projecting within the casing and is
closed by a dished disc valve having indiarubber or other packing inserted within
an annular recess around its edge.
This valve is operated by a screwed stem formed in one with or secured to it
and screwing through a bridge piece or perforated plate secured on front of air
outlet from the casing, a small operating hand wheel being secured to the end
of the stem.
Under another modification the hood part of casing is dispensed with and the
air directed in a vertical direction from the cylindrical part. In this case the
closing dished dise valve is operated by a vertical spindle screwing through a
bridge piece at top of casing, and forms a fluid tight joint with the lower end of
cylindrical part. The float valve works on the spindle between stops or shoulders
on the spindle and forms fluid tight joints with the upper flange of cylindrical

page_text: part and with the upper stop on spindle. Instead of the upper stop a fixed bridge
piece may be used or both may be dispensed with.

Improvements in and relating to Ships' Side Lights and Ventilators.
I, EDMUND SHARER, of The Fairfield Shipbuilding and Engineering Company,
Limited, Fairfield Works, Govan, in the County of Lanark, Shipbuilder, do hereby
declaro the nature of my invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement in writing reference being made to the accompanying sheet of illustrative
drawings:-
-
This invention has reference to and comprises improvements in and relating to
ships' side lights and ventilators for cabins and the like by which these are used
in combination and means adopted for preventing the entry of water within the
vessel, when at any time the ventilating opening is temporarily immersed and for
closing same when the sea is heavy.
And in order that my said invention may be properly understood I have here-
unto appended a sheet of explanatory drawings in which Figuro 1 is a sectional
sido elevation and Figure 2a front view of a combined ship's side light and
ventilator constructed according to my improvements, while Figure 3 is a
sectional side elevation of the ventilator portion showing another modification.
Referring to these drawings:-In carrying into practice the improvements of
this invention the frame A of the circular or otherwise shaped side light A by
which it is secured to the ship's side is extended upwards and has another opening A²
for ventilating purposes formed therein which is preferably fitted or covered
with a grating B of metal fretwork or the like but is otherwise permanently open.
On the inside of the vessel and secured to the frame is a casing C forming an sir
inlet or duct which is fitted with a float valve D and a closing valve E constructed
and arranged under one modification, as illustrated by Figures 1 and 2, ns
follows:
Within the casing C the air passages C is formed of a cylindrical shape with
an open bottom and an inwardly projecting flange around its lower edge while
the upper part is formed as a hood so as to allow the air to flow out in a hori-
zontal direction. At the top of the cylindrical part another inwardly projecting
flange is formed and indiarubber or other packing is inserted within an
annular recess formed in the lower face of the flange C³. A float valve D preferably
a hollow metal float works within the cylindrical part and is guided and supported
by stepped feathers c secured or formed therein and by a spindle D working
through a bridge piece or perforated diaphragm formed or secured above it.
The top edge of this float valvo is formed as a ridge d to make a fluid tight joint
with the annular packing when pressed into contact by the float valve rising
when water enters within the casing C, and so prevents it passing into the cabin
or vessel. The opening at the top of the casing admitting the air to the interior
of cabin or vessel is formed circular and has a flange C³ projecting within the
casing and is closed by a dished valve E having indiarubber or other packing c
inserted within an annular recess around its edge.
This valve is operated by a screwed stem E formed in one with or secured to
it and screwing through a bridge piece E or perforated plate secured on front
i

page_text: of air outlet from the casing, a small operating hand wheel E being secured to
the end of the stem E¹.
Under another modification, as illustrated by Figure 3, the hood part of casing C
is dispensed with and the air directed in a vertical direction from the cylindrical
part C. In this case the closing dished disc valve E is operated by a vertical
spindle E screwing through a bridge piece E at top of casing C, and forms a
fluid tight joint with the lower end of cylindrical part. The float valve D works
on the spindle E¹ between stops or shoulders et on the spindle E¹ and forms
fluid tight joints with the upper flange Cs of cylindrical part C and with the
upper stop el on spindle. Instead of the upper stop e¹ a fixed bridge piece may
be used or both may be dispensed with.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
First. Combined side lights and ventilators for ships fitted with self closing
float and hand operated valves constructed and arranged all substantially as herein
described and illustrated by Figures 1 and 2 of the accompanying drawings.
Second. Combined side lights and ventilators for ships fitted with self closing
float and hand operated valves constructed and arranged all substantially as herein
described and illustrated in reference to Figure 3 of the accompanying drawings.
