PROVISIONAL SPECIFICATION.
Improvements in the Side Ports of Sailing Ships and Well-deck
Steamers.
I, JAMES FAIRLIE of 24 Oswald Street, Glasgow, in the County of Lanark, North
Britain, Shipowner do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the side ports of sailing ships and well-
deck steamers, and has for its object an automatic arrangement for the purpose of
quickly clearing a ships deck of any water that may come over the bulwarks, and at
the same time preventing the admission of any water through the port, and my
invention also relates to incans for preventing the ropes or other gear from being
washed through the port, as happens with the ports at present in use.
In carrying out my improvements, in lieu of the port, when in its normal condition
being hinged flush with the bulwarks, I hinge the said port at an angle outwards
therefrom and provide the port so mounted with angular shaped side pieces in such a
manner as to provide a false bottom or mouth which I close with a balanced flap.
The said flap is pivoted between the two said sides of the port, and is balanced by
an arm at the inside of the bulwarks provided with an adjustably mounted weight.
I cover up the port-hole at the inside of the bulwarks with a wire guard, mounted
upon the edges of the triangular shaped sides, so that in its normal position it is
flush with the bulwarks.
The said guard allows water to run out, but prevents any solid articles, such as
ropes, escaping.
When in action, any water that has flowed over the bulwarks, rushes through the
guard and on to the balanced flap, which opens automatically as soon as the weight of
water thereon overcomes the balance weight; and as soon as the flap is relieved of the
water it automatically closes, but it also, under any circumstances closes automatically
if a sea strikes the outside of the flap; or if the ship lies over at such an angle as to
submerge the flap; the flap is instantly closed against the entrance of any sea.
When in harbour the port may be closed flush with the bulwarks, and be in the
position of ordinary ports; and for this purpose I provide the inside of the bulwarks
with catches for the purpose of locking and unlocking the wire guard when it is
required to open or close the port.

Improvements in the Side Ports of Sailing Ships and Well-deck
Steamers.
1, JAMES FAIRLIE of 24 Oswald Street, Glasgow, in the County of Lanark, North
Britain, Ship-owner, 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 the side ports of Sailing Ships
and Well-deck Steamers has for its objects to provide an Automatic arrangement of
ports for the purpose of quickly clearing a ship's deck of any water that may have
come over the bulwarks, while at the same time it also prevents any water from
getting admission by the port, and also prevents any loss of ropes or other gear.
by their being washed through the ports as happens with ports at present in use.
In carrying out my Invention 1 employ a port plate hinged at an angle outwards
from the ship's side, and provided with two angular shaped side pieces so as to allow
of a mouth being formed, which is then closed with a falso bottom or balanced flap,

page_text: which is pivoted between the said side pieces, and balanced on the inside of the
bulwarks by means of an arm carrying an adjustable weight.
On the inside edges of the angular side pieces I mount a wire guard or cover,
which in its normal position is flush with the bulwarks. This guard allowing of the
free outlet of water but preventing any solid articles such as rope, escaping.
The whole arrangement being such that the port may be closed flush with the
bulwarks when in port or harbour, or opened and the guard flush with the bulwarks
when at sea, the said positions being obtained by mounting suitable catches for
locking or unlocking the wire guard when required.
In order that my said Invention may be more readily understood and easily carried
into effect, I will now proceed to describe it, reference being made to the accompany-
ing sheet of Drawings, Figure 1, of which is an elevation looking from the deck of
the ship when the port is open, while Figure 2, is an end elevation of the port open
as when at sea, and Figure 3, a sectional elevation of the port closed as when in port
or harbour.
A is the port plate which I provide with suitable hinges a, which are fastened to the
ship's side B, so as to enable the port to be opened or shut. The said port plate has
two angular shaped side pieces mounted on it, so as to form a mouth or opening
for the outlet of the water from the ship's deck, this mouth or opening is provided
with a false bottom or balanced flap D, which is pivoted between the two side pieces
at d, and balanced by means of the arm E, and adjustable weight F, which projects
inside the bulwarks. The said side pieces C have fixed to their inner edges a wire
guard or cover G for preventing any solid articles such as rope from passing through
the port. This guard or cover being held in the desired position by means of 2 or
more suitable catches H which are mounted on the ship's side B.
The working of the whole arrangement being as follows:-When the ship is at
sea the port is open, as shown in figures 1 and 2, so that on any water which has
flowed over the bulwarks rushing through the guard G on to the flap D), the said flap
opens automatically when the weight of the water on it has counterbalanced that of
the weight F, thus allowing of the free outlet of the water, any solid article being at
the same time prevented from escaping by means of the guard G. (The position of
the flap D, and weight F when open is shown dotted at D and F¹ figure 2). This
flap D at all times prevents any water from rushing in through the port, as the instant
a sea strikes the said flap on the outside it automatically closes and thus prevents the
water from rushing in, or if the ship lies over at such an angle as to submerge the
flap, the flap is held closed by the pressure of the water on its outside, thus only
allowing water to rush out through the port but not in through the port.
When in port or harbour the port is closed as shown in sectional elevation
Figure 3, the port plate A in this instance being flush with the ship's side.
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
First. In sailing ships and well-decked steamers, the employment of an automatic
working port for allowing the egrees but preventing the inlet of water substantially
as herein before described with reference to the accompanying Drawings.
Second. In sailing ships and well-decked steamers, the employment of a hinged
port plate A, having a balanced flap D, substantially as and for the purposes
herein before described and shown in the accompanying Drawings.
Third. For the ports of sailing ships and well-decked steamers the employment
of a guard G, in combination with the port plate A, and flap D, substantially as
and for the purposes herein before described with reference to the accompanying
Drawings.
