PROVISIONAL SPECIFICATION.
Improvements in Ships' Side Lights or Scuttles for Ventilating.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Company of Deptford
in the County of Kent and DUNCAN WILLIAM MCLAREN in the employ of the
said firm, Engineers do hereby declare the nature of this invention to be as
ollows:-
:-
These improvements refer to ships' side lights or scuttles and have for their
object to render them ventilating or adapted for the supply of fresh air to the
interior of the deckhouse or other structure fitted with such side lights without
opening the glass doors of such lights or irrespective of their being fitted with
doors or not, the construction being of such a character that any water spray or
rain entering the ventilator part of the side light shall readily find its way out of it
again, means being also by preference provided for regulating the air supply and
for closing up the ventilator tightly when desired.
We chamber out the frame of the side light in the upper part and down the
sides till about the middle or somewhat below it where the chamber is made sloping
and is provided on each side with a number of small openings and we continue the
upper part of the chamber into an enlargement or box which has an outlet opening
or openings towards the inboard side of the side light; this opening is fitted with
one or more circular or other hit and miss regulating valves, and also if desired
with an outer door or the latter door may form the regulating valve or flap for
closing up the ventilator: The air enters the aforesaid chamber by the aforesaid
small openings on each side of the frame. The ventilator box or valve box may
be provided with a central partition for creating an in current and an out current.
Any spray entering one set of openings say in the forward motion of the ship
will be broken up by the small inlet holes and any small portion entering the
chamber will be thrown up more or less to the top of the chamber and there
descend on the other side and pass out of the openings on that side.
The invention is applicable to lights fitted with movable doors or otherwise.

Improvements in Ships' Side Lights or Scuttles for Ventilating.
We, EDWIN JAMES PRESTON of the Firm of J. Stone and Company of
Deptford, in the County of Kent, and DUNCAN WILLIAM MOLAREN in the
employ of the said firm Engineers 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 :-
These improvements refer to side lights or scuttles and have for their object to
render them ventilating or adapted for the supply of fresh air to the interior of
the cabin, deck house, or other structure fitted with such side lights, without
opening the glass doors of such lights or irrespective of their being fitted with
doors or not the construction being of such a character, that any water spray or
[P1

page_text: rain entering the ventilator part of the side light shall readily find its way out of it
again, means being also by preference provided for regulating the air supply and
for closing up the ventilator tightly when desired.
We chamber out the frame of the side light in the upper part and down the
sides till about the middle or somewhat below it where the chamber is made sloping
and is provided on each side with a number of small openings and we continue the
upper part of the chamber into an enlargement or box, which has an outlet opening
or openings towards the inboard side of the side light; this opening is fitted with
one or more circular or other hit and miss regulating valves and also if desired
with an outer door, or the latter door may form the regulating valve or flap for
. closing up the ventilator. The air enters the aforesaid chamber by the aforesaid
small openings on each side of the frame. The ventilator box or valve box may
be provided with a central partition for creating an in-current and an out-current.
The invention is applicable to lights fitted with movable doors or otherwise.
Fig. 1 of the accompanying drawings is a sectional elevation and Fig. 2 a
_vertical cross section of a ventilating side light or scuttle suitable for a deckhouse
or other structure. The upper part and sides of the frame is formed with
chambers A provided with a number of small holes A¹ and continued up into an
enlargement or box A' which has outlet openings A³ towards the indoor side of
the scuttle. B is a hit-and-miss valve with corresponding openings and serving to
regulate the air inlet from the holes A¹ and chambers A to the interior of the
cabin or deckhouse. Round hit-and-miss valves may be used instead of those
shown here and in the following figures. C is an outer door for closing up the
ventilating scuttle. It is hung from an upper fulcrum C¹ and is provided with joint
ring C. It is arranged to be fastened by hinge bolt at each side. The lateral
chambers A may be provided with plates A* or other projections to keep back the
spray that may enter the holes A¹ along with the air. The box A' may be
provided with partitions A' and A' for creating and guiding an in-current and an
out-current. D and E are the glazed door and the dead door, but we do not here
claim the construction of these doors.
Any spray entering one set of openings A', say in the forward motion of the
ship, will be broken up by the small inlet holes (and plates A* if fitted therewith)
and any small portion entering that side chamber A will be thrown up more or less
to the top of same and then descend into the other side chamber A and pass out of
the openings A' on that side.
Figs. 3 and 4 are elevation and vertical cross section shewing the invention
applied to a construction of scuttle described in Patent Specification 9543 of 1888
with vertically pivoted glazed door D and ring F with rack and pinion motion for
turning the ring F thereon under slanting cleats and tightening it against them
and thus compressing the rubber ring F against the door D and scuttle frame so
as to hold the door D firmly in position.
Figs. 5 and 6 are sectional elevation and vertical cross section shewing the
invention applied to another such Stone & Co. construction of scuttle with pivotted
glazed door D with tightening ring F having rack and pinion motion for turning
it under slanting cleats and thus compressing the rubber ring F against the door D
so as to hold it firmly in position.
Figs. 7 and 8 are similar views shewing the invention applied to another
such Stone & Co. construction of scuttle with hinged glazed door D with tightening
ring F having rack and pinion notion for turning under slanting cleats and thus
pressing the door D against the rubber ring D' and making joint.
Figs. 9 and 10 are sectional elevation and vertical cross section of the upper
part of another such Stone & Co. construction of scuttle with the invention
applied thereto. In this case hinged valves H of very light construction are fitted
so as to momentarily close the ventilating box on one side or the other of the
mid-partition A' in case spray should be thrown up one of the side chambers A
with any considerable force, while the other valve H would or might remain open,
as shewn, the valves H thus assisting the spray, which may enter by the holes A'

page_text: in one chamber A to pass out by the holes A¹ in the chamber A on the opposite
side, as described with reference to Figs. 1 and 2.
Figs. 11 and 12 are similar part views of a similar kind of scuttle, where the
valves H however are made ball shaped and adapted to be thrown from their lower
rests or bearings H¹ up against upper seats H' and thus momentarily close the
ventilating box on one or both sides of the mid-partition A*.
Figs. 13 and 14 are part sectional side views of the upper part of scuttle in
which the hit-and-miss valve B is omitted, and the outer door C is pivotted below
at C' and fastened at the top. In Fig. 13 this door can be left more or less open
as desired, any one of the teeth of the rack I pivotted at I¹ being adapted to gear
with the peg C on the door C. In Fig. 14 the opening of the door is not made
adjustable and its hinge has merely a heel C* which in the open position rests on a
lug on the box.
The door arrangements in Figs. 13 and 14 may be used in connection with the
valves H shewn in Figs. 9, 10, 11 and 12, without hit-and-miss valve B.
Any spray entering one set of openings A' in the above described scuttle, say in
the forward motion of the ship will be broken up by the said small openings and
any small portion entering that chamber A will be thrown up more or less towards
the top of the chamber and descend on the other side and pass out of the
openings A¹ on that side.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Constructing the frames of ships' scuttles for cabins, deckhouses and other
structures, with lateral chambers communicating at their lower part by small
openings with the outer air, for the purpose of ventilation, and terminating above
in a box closed with a valve or valves, which open towards the interior of the
cabin, deckhouse or other structure, all so arranged that any spray entering by the
holes in one lateral chamber may pass out by the holes in the other, substantially
as set forth.
2. The combination with the lateral chambers firstly claimed of spray deflectors.
arranged therein, substantially as set forth.
3. The combination with the upper box, of partitions for dividing the ingoing
from the outgoing current, substantially as set forth.
4. The combination with the lateral chambers and the upper box, of partitions
for dividing the ingoing from the outgoing currents and of valves which close
automatically or one of them in case of spray being thrown up into the box,.
substantially as set forth.
5. The constructions of ventilating ships' scuttles described with reference to
Figs. 1 to 12.
6. The constructions of ventilating ships' scuttles described with reference to.
Figs. 13 and 14.
