Improved Means and Appliances for the Dislodging and Destruction
of Barnacles and the like from the Hulls of Sea-going Vessels.
I, RICHARD BARRINGTON DAINES, of 5, St. James Road, Gravesend, County of
Kent, Trinity Pilot (Sea), do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to improved means and appliances for the dislodging
and destruction of barnacles and the like from the hulls of sea-going vessels.
For the purpose of my said invention, I employ ordinary paraffin oil, or an oil
having life destructive property, such as naphtha, petroleum, or a mixture of
any or all of the above either for use alone or mixed with other liquids, say,
water ammonia, an acid, or the like which I preferably pass by gravitation
to a pipe or pipes from the deck of a vessel downwards for egress by spray or
otherwise from at or near the keel of a vessel, so that in rising against the hull, it
may attack the barnacies and other marine growth and dislodge the same therefrom,
the fish, insects, and other debris adhering to the hull being suffocated or reduced
in bodily strength as to drop off.
The liquid so employed may be forced by pump and I may make the convey-
ing pipes as part of the structure, or affix them in any desired manner and at
suitable positions.
This cleansing of a ship's hull may be effected at any part of the ship's voyage,
such as when progress is reduced by such obstructions, or while at anchor, or
when hove to for the purpose, the distribution of the oil being regular or inter-
mittent as found necessary.
If perforated keel pipes be arranged fixed quantities of the oil can be forced
through from above, and this oil having a tendency to rise proportionately to
its quality and specific gravity will lick against the ship's hull and so destroy or
so stupefy adherent life that the hull becomes clean.

page_text: what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement: -
This invention relates to improved means and appliances for the dislodging
and destruction of barnacles and the like from the hulls of sea going vessels.
For the purpose of my said invention, I employ ordinary paraffin oil, or an oil
having life destructive property, such as naphtha, petroleum, or a mixture of
any or all of the above, either for use alone or mixed with other liquids, say,
water, ammonia, an acid, or the like which I preferably pass by gravitation
from a tank A (see annexed drawings) to a pipe or pipes B from the deck of a
vessel downwards for egress by spray or otherwise from at or near the keel C of
a vessel D, so that in rising against the hull E it may attack the barnacles and
other marine growth and dislodge the same therefrom, the fish, insects, and
other debris adhering to the hull E being suffocated or reduced in bodily strength
as to drop off.
The liquid so employed may be forced by pump, and I may make the convey-
ing pipes B as part of the structure, as at Figure 1, or affix them in any desired
manner and at suitable positions either down the sides of the vessel, as at Figure 2,
or down the stern of a vessel, as at Figure 3, where the end may be perforated,
as at Figure 3, or when so employed down the stern of a vessel, the pipes may
have branched end, as at Figure 4.
This cleansing of a. ship's hull may be effected at any part of the ship's voyage,
such as when progress is reduced by such obstructions or while at anchor, or
when hove to for the purpose, the distribution of the oil being regular or inter-
mittent as found necessary.
If perforated keel pipes be arranged, as at Figure 3, fixed quantities of the oil
can be forced through from above, and this oil having a tendency to rise pro-
portionately to its quality and specific gravity will lick against the ship's hull
and so destroy or so stupify adherent life that the hull becomes clean.
In some cases, the perforated distributing pipes may run the whole length of
the vessel, so that the destructive agent can be distributed all over the hull of the
vessel, this is especially suitable for use when the vessel is at anchor in still waters,
but when the vessel is on the move, or a tide is running it is only necessary to
apply the pipes at the stern of the vessel, the onward motion of the vessel, or the
tidal action distributing the oil or other destroying agent all over the hull of
vessel for the purpose intended.
It will be understood that the pipes may emanate from any part of the ship
according to requirements and may be permanent with the ship, or be affixable
thereto when required for use and the pipes may be cleaned or cleared at various
times by a rod or wire.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
The improved means and appliances for the dislodging and destruction of bar-
nacles and the like from the hulls of sea going vessels, consisting in passing by
gravitation or pressure through a pipe or pipes suitably arranged a destroying
agent such as paraffin oil, naphtha, or the like either alone or mixed with another
liquid for allowing such liquid to be disseminated all over the hull of a vessel,
substantially as set forth.
