Complete Specification Accepted, 13th Apr, 1889
I, WILLIAM RODGER HAYES of No 8 Derby Terrace Harrow Lane Poplar,
London, E Carpenter, do hereby declare the nature of this invention to be as
follows
-
In the specification of my invention No 15,869 dated 18th November 1887 I have
described an appliance capable of ready adjustment to, and removal from the side
ports or scuttles of ships, with a view to facilitate the ventilation thereof The device
according to my present invention is designed as a means of automatically closing
and opening the ventilating ports or scuttles of ships without the necessity for
operating upon the ordinary glazed door of said ports or scuttles said operation
requiring to be attended to frequently in cases of sudden changes, from a rough sea-
when it would be necessary to close the ports,-to such a state as would allow of the
side ports or scuttles remaining open I am enabled also by the means which I
employ as hereinafter described, to utilize the device according to my invention, to
effect the ventilation of other parts of the vessel, by a system of ducts or chinnels
leading to the operating part of the device, and, as a supplementary means of
ventilation, apart from that effected through the ports or scuttles aforesaid
The device according to my invention consists of a pipe or tube of requisite area,
adapted to an opening formed in the ships side at a suitable distance above the water
line Within said tube or pipe, which serves the purpose of a cylinder, is arranged
a piston having a piston rod, the upper part being preferably hollow-attached
thereto
In said hollow piston rod takes the end of a rod or spindle attached to a sluice
valve like glazed door or shutter working within a suitable casing, employed for
closing the port or scuttle when operated by the action of the waves beneath the
piston aforesaid, which, forcing the latter up the cylinder, imparts a corresponding
motion to the sluice-valve-like door or shutter by means of the valve rod above
021

page_text: described, said valve rod being secured to the piston rod by means of a suspended
cottar or equivalent Suitable means are employed to reduce the friction of the
sliding sluice valve like door or shutter to a minimum, and at the same time to
ensure a water tight joint
In calm weather the piston and attachments would be at the bottom of the
cylinder above mentioned, and thereby uncover the port or scuttle in the ship's side,
and, in order to utilize, for ventilating purposes the reduced motion imparted to the
piston by the wash of the sea against the ship's side, the cottar or equivalent ahove
mentioned would be removed, thus allowing of the free movement of the piston,
relieved of the weight of sliding sluice valve aforesaid, this reduced motion would
be utilized to pump out vitiated air and injurious vapours from the different parts of
the ship to which my improved appliance may be adapted by means of the ducts and
channels herein before referred to, which latter are provided with the requisite check
and delivery valves, and thus serve as herein before stated as a supplementary means
of ventilation apart from that effected through the ports and scuttles aforesaid

page_text: Improvements relating to and in the Means Employed for the
Ventilation of Ships
I, WILLIAM RODGER HAYES of No 8 Derby Terrace, Harrow Lane, Poplar,
London, E Carpenter, 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
In the specification of my Invention No 15869 dated 18th November 1887 I have
described an appliance capable of ready adjustment to, and removal from the side
ports or scuttles of ships, with a view to facilitate the ventilation thereof The device
according to my present Invention is designed as a means of automatically closing
and opening the ventilating ports or scuttles of ships without the necessity for operating
upon the ordinary glazed door of said ports or scuttles, said operation requiring to be
attended to frequently in cases of sudden changes from a rough sea-when it would
be necessary to close the ports,-to such a sea as would allow of the side ports or
scuttles remaining open
I am enabled also by the means which 1 employ as herein-
after described, to utilise the device according to my present Invention, to effect
the ventilation of other parts of the vessel, by a system of ducts or channels leading
to the operating part of the device, and, as a suplementary means of ventilation
apart from that effected through the ports or scuttles aforesaid
In this
The device according to my invention which is illustrated in the accompanying
drawings consists of a pipe or tube A of requisite area, adapted to an opening a
Within said
formed in the ship's side at a suitable distance above the water line
tube or pipe A, which serves the purpose of a cylinder, is disposed a piston B having
a piston rod b the upper part being preferably hollow-attached thereto
hollow piston rod takes the end of a rod or spindle Cattached to a sluice-valve like
glazed door or shutter D, working within a suitable casing, employed for closing
the port or scuttle E when operated by the action of the waves beneath the piston B
aforesaid, which, forcing the latter up the cylinder A imparts a corresponding motion
to the sluice-valve-like door or shutter D by means of the valve rod C above
described, said valve rod being secured to the hollow piston rod 7 by means of a
cottar d or equivalent A plug
e is adapted to a hole or aperture in the cylinder A
to allow of access to, and removal, when desired, of the cottar & above mentioned
Suitable provision is made to reduce the friction of the sliding sluice-valve-like
door or shutter D to a minimum, and at the same time to ensure a watertight
Joint
In calm weather the piston B and attachments would be at the bottom of the
cylinder A as shown in the drawings, hence the port or scuttle E would be open, and,
in order to utilise, for ventilating purposes, the reduced motion imparted to the
piston by the wash of the sea against the ships side, the cottar d or equivalent
would be removed, thus allowing of the free movement of the piston, relieved of
the weight of the sliding sluice-valve D aforesaid This reduced motion would be

page_text: utilised to pump out vitiated air and injurious vapors from the different parts of the
ship to which my improved appliance may be adapted, by means of the ducts or
channels Fibove referred to, which latter are provided with the requisite check
and delivery valves f, f¹ and thus serve, as hereinbefore stated, as a supplementary
means of ventilation apart from that effected through the ports and scuttles E
aforesaid
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 15 -
First The automatic opening and closing of the ports or scuttles of ships sub-
stantially as herein described and shown in the accompanying drawings
Second In the automatic opening and closing of the ports or scuttles of ships
the employment of a piston working in a cylinder, said piston being provided with a
hollow piston rod, to which is attached by means of a rod, a sluice-like valve or
shutter, substantially as and for the purpose herein described and shown
Third In the appliance herein described the utilisation of a piston working in a
cylinder for pumping out vitiated air, and thus serving as a supplementary means of
ventilating a ship substantially as herein set forth and shown
