Improvements in Apparatus for Pouring Oil on the Waves from
Ships at Sea.
I, JOHN BENJAMIN WOOLLEY, of Como Lodge, Coombe Road, South Croydon,
in the County of Surrey, Master Mariner, do hereby declare the nature of my said
invention to be as follows:-
The utility of oil as a means of lessening the violence and destructive force of
the waves under certain conditions being now generally recognised, a satisfactory
apparatus for pouring the oil on the waves to the windward of the ship has become
a desideratum and my invention is intended to supply this want.
According to my invention I provide a cylindrical vessel in which the oil to be
used is placed and from which it is expelled by suitable mechanism into and
through a flexible pipe, or hose, and so on to the water.
The cylindrical vessel has on its upper surface a covered cup, or funnel-shaped
vessel communicating with its interior, and has at or near the lower part an outlet
with a cock for regulating the flow of oil and a nozzle to which the flexible pipe,
or hose, is attached. Within the cylinder is a piston with a port, or ports, or
openings through it, closed by a valve, or valves, on the under surface so as to
admit of the oil passing downwards through the piston but not upwards. The
piston is fitted with a piston-rod, or other device, for raising it, and is pressed
downwards by a spiral spring within the cylinder, or other suitable device.
When the apparatus is to be used, oil is poured into the cylinder through the
funnel-shaped vessel, and the piston raised, thereby allowing the oil to pass into the
part of the cylinder below the piston, the piston is then allowed to descend and
presses on the surface of the oil which is thereby expelled through the pipe, the
rate of flow being regulated by means of the cock.
The success of the operation very much depends on the oil being poured on the
sea in a proper position in relation to the ship, that is to say, to the windward, or
nearly so, and at a proper distance.
In order to carry the free end of the pipe to the required point it is attached to
the discharge-cock, or nozzle, of the cylinder and passed preferably through the
scupper holes, or mooring pipes, and its free end attached to a suitable float."
A line is also attached to the float to act as preventer and to take the strain off
the flexible pipe.
For running before a sea, one apparatus may be placed on each side of the vessel.
a little before the midships.
With sea on the quarter, place one apparatus on the quarter and another on the
fore part of the bridge.
With beam sea place one apparatus as far forward as possible and keep the line
attached to the float well forward, so as to keep the discharge pipe and float well
clear of the ship's side.

float to act as a preventer and to take the strain off the pipe.
For running before a sea one apparatus may be placed on each side of the vessel
a little before the midships.
With a sea on the quarter it is best to place one apparatus on the quarter and
another on the fore part of the bridge.
With a beam sea I prefer to place one apparatus as far forward as possible and
keep the line attached to the float well forward, so as to keep the discharge pipe
and float well clear of the ship's side.
In many circumstances however it is sufficient and indeed preferable not to use
a float but simply to fix the rigid discharge pipe over the ship's side.
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:
1. The hereinbefore described apparatus for pouring oil from ships, boats and
the like at sea upon the waves.
2. An apparatus for pouring oil from ships, boats, and the like upon the sea
waves, characterized by a cylinder A, containing a piston E, capable of allowing
the oil to pass through it downward but not upwards, a spiral spring K actuating
the same, a piston rod I, an inlet and an outlet with regulating cock or valve
for the latter all substantially as described.
3. An oil reservoir from which the oil is expelled by a piston actuated by a
spring substantially as described and for the purpose set forth.
