PROVISIONAL SPECIFICATION.
Improved Ships' Sidelight and Automatic Ventilator, for Lighting
and Ventilating Ships between Decks, and the like.
JOHN SHAW, 22 Rosehill Terrace Willington-on-Tyne, Northumberland
Ironfounder do hereby declare the nature of this invention to be as follows:-
:-
This invention consists of frame and casement, made of brass or other material,
to give light and ventilation, where required. The frame has two inlets through
the sides to allow fresh air to pass into each ventilator one on each side of
frame. The frame is fixed to inside of ship for receiving casement, and is provided
with nuts and bolts. The frame having a round edge to press into a cushion ring,
which is made of india rubber or other material to make it water tight when
screwed up.
The ventilators are provided with one or more loose shutters hung out of centre.
The casement for glass has two inlets to correspond with those in frame when
open for ventilation, with a recess for ring cushion, it has two facings round
outside, which are machined to fit inside of frame, and slots for passing round screw
bolts under the nuts. When frame is fixed to inside of ship the casement is put
inside of frame, when turned round against the screw bolts, which are fixed to
correspond with inlets, which allow fresh air to pass through the ventilators into
inside of ship, when screwed up it is perfectly watertight. The inlets for fresh air
are between the outside of ship and glass fixed in casement, so that there is a
continual supply of fresh air passing through the ventilators. In case of a storm-
when the sea is lashing against the glass, the water rushes into the inlets against
the bottom part of loose shutter which is hung out of centre and which forces it
back, and closes the air passage and prevents the water from rising, as soon as the
sea goes back the shutters open again. It is so arranged that the ventilators can
be shut off at any time, by turning casement round, and screwed up again by same
appliances as above, it is then perfectly watertight.
There is a dead light provided when required, also a lining if necessary to
replace casement in conjunction with deadlight.

I, JOHN SHAW 22 Rosehill Terrace Willington-on-Tyne Northumberland
Ironfounder 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 consists of a frame and casement made of brass, or other material
to give light and ventilation where required. The frame is provided with inlets
between the outside of the ship, and glass in the casement, for the passage of air
into the ship or cabin through the ventilators. The frame is fixed to the shell
plating, or other parts of the vessel, and is also provided with a projecting edge for
making the casement, which holds the glass, watertight, when screwed up with
suitable fastenings.
The ventilators are provided with shutters, or floats made of copper, or other

page_text: suitable material, hung out of the centre, or made without shutters, or floats, and
can be applied to any design of ships side, or deck house light.
In the accompanying drawings
Figure 1 is a front elevation of the light, and the ventilators, with one of the air
chamber doors removed, showing the interior of the ventilators.
Figure 2 is a horizontal section through line C. D. Fig. 1.
Figure 3 is a side view on the line A. B Fig. 1.
Figure 4 is a storm water-tight cover and seat.
Figure 5 is a horizontal section of an air chamber through ventilator.
Like letters of reference indicate corresponding parts throughout the drawings.
N, Fig. 1, is the frame fixed to ships shell R, R, Fig. 3. which receives the
casement K Fig. 1. containing the glass M Fig. 1. E, E, Fig. 1, are the air
chambers, which can be applied to any design of ships side or deck house light.
P, P, Fig. 2. are the inlets to the air chambers E, E, Fig. 2. between the outside
of the ship R., and the glass M. in the casement K, Fig. 2. G, G, Fig. 1. are the
shutters, or floats, which close the air passage when the water enters the ventilators.
H, H, Fig. 1, are the partitions faced for the shutters G, G, Fig. 1. to butt
against. F Fig. 1, is one of the air chamber doors. J. J. Fig. 1, are the water-
tight covers for shutting off the ventilators, when required. Q. Q. Fig. 1, are the
fastenings for same. L Fig. 1, is the deadlight door. S. S Fig. 1, are the
fastenings for casement K Fig. 1, which is made to come flush with the inlets in
the frame N Fig. 1. so that there is a free passage for the air to enter into the
ventilators.
The casement K which holds the glass M. is provided with a recess for a cushion
ring, made of india rubber, or other suitable material, which when closed comes in
contact with a projection on the frame, which when screwed up with the
fastenings on the frame, makes a watertight joint, and leaves a free passage for the
air to enter into the ventilators, between the outside of the ship, and the glass, in
the casement, when the frame is fixed to ships shell.
To prevent water entering the ship, each ventilating passage E is provided with
one or more hinged lifting shutters or floats G. so that when water enters the
ventilators E, its passages is cut off. These shutters G, are made light in structure
to float easily, and faced with india rubber or other suitable material. They are
slung easily, and when open to such an angle, that water entering it catches the
bottom and lifts the shutter G, up against the partition H, in the ventilator, and
makes a watertight joint, and prevents the water rising up inside the ventilator.
On the removal of the water pressure the shutter or float G falls back to the
hanging angle owing to its weight, and allows the air to pass through the air
chamber E into the ship or cabin.
A storm cover J, is provided with a watertight seat, by means of which the
ventilating openings E, can be entirely shut off.
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
1st. A combined ships sidelight and ventilator.
2nd. A ships sidelight frame, with inlets for the air to pass into the vessel, placed
between the outside of the ship, and the glass in the casement, when the frame is
fixed to the ships shell.
3rd. Shutters or floats hung out of the centre in the ventilators.
4th. A ships sidelight and automatic ventilator, constructed substantially as
described with reference to the drawings, and operating as, and for the purposes
specified.
