PROVISIONAL SPECIFICATION
Improvements in Apparatus for Distributing Oil on the Waves of
Rough Seas to Moderate or Subdue their Turbulence.
We, PETER DOUGLAS MURRAY, of 3 St. Pauls Villas, Rock Ferry, in the
County of Chester, and PETER LAMONT, of 68, Selborne Street, Liverpool, in the
Lake Huron,"
County of Lancaster, Captain and Engineer respectively of .s.
do hereby declare the nature of this invention to be as follows:-
"
This invention has for its object an apparatus for distributing oil on the wave; of
rough seas to moderate or subdue their turbulence and is distinguished from many
of those hitherto in use in that it is designed to be mounted in a steamer or sailing-
vessel, on a harbour pier, or other situation instead of being adapted to be thrown
into the sea.
In carrying out our invention as applied to a maritime vessel we provide a
cylinder mounted vertically in a suitable position and having a piston and piston
rod moving vertically therein. The latter is provided at its extremity with a
removable weight. The piston may be packed with a leather ring or in any other
suitable manner.
The cylinder is connected with the oil store tanks or barrels by
means of a pipe having a suitable valve under the control of those in charge.
Orifices are made in the starboard and port bows of the vessel preferably
about 2 or 3 feet below the load line, and the oil is led from the cylinder to these
orifices by means of pipes controlled by valves.
The mode of action is as follows:-
To fill the cylinder with oil the piston is raised to the top of the cylinder, the
valve in the feed pipe is opened, and the oil flows from the tanks into the cylinder.
The feed pipe is now closed and the weight is put on the top of the piston thereby
compressing the oil in the cylinder.
When it is desired to subdue the waves the valve or valves in the exit pipe are
opened, and the oil flows out through the orifices in the starboard or port sides of
the bow.
If desired several ejection orifices may be provided on each side of the vessel.
The arrangement of the apparatus for harbour piers or other situations is some-
what similar to the above and does not require further description.

Improvements in Apparatus for Distributing Oil on the Waves of
Rough Seas to Moderate or Subdue their Turbulence.
"
We, PETER DOUGLAS MURRAY of 3, St. Pauls Villas, Rock Ferry in the
County Chester and PETER LAMONT of 68, Selborne Street, Liverpool in the
County of Lancaster, Captain and Engineer respectively of s.s. "Lake Huron
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 has for its object an apparatus for distributing oil on the waves
of rough seas to moderate or subdue their turbulence and is distinguished from

page_text: many of those hitherto in use in that it is designed to be mounted in a steamer. or
sailing vessel, on a harbour pier, or other situation instead of being adapted to be
thrown into the sea.
The sheet of drawings hereunto annexed shows an apparatus in accordance with
this invention, similar letters of reference indicate like parts in each of the figures
on such sheet.
Figure 1 being a sectional elevation of the cylinder with its allied parts, from
whence the oil is distributed,
Figure 2 is a plan view of Figure 1, and
Figure 3 shows in outline the cross section of the bows of a ship having fitted in
them such cylinder aforesaid along with the series of pipes or tubes leading to and
from the cy linder as hereinafter fully described.
In carrying out our invention as applied to a maritime vessel, we provide a
cylinder A mounted vertically in a suitable position and having a piston B and
piston rod C moving vertically therein. As will be seen from Figure 2, for
convenience in mounting this cylinder A, it has cast on its side a bracket D whereby
the cylinder, with its parts, can be bolted in an upright position at any convenient
part in the ship. The piston rod C is provided at its extremity with a removable
weight E. This weight for the purpose for which it is required must be con-
siderably heavy, it is applied in any convenient manner for instance by attaching
it to the piston rod C by means of a washer G' resting on a small turned neck and
a nut G. Just under such weight E, a cross bar F is preferably arranged so that
its ends can be grasped. By this means the weight E can be easily removed from
off the end of the piston rod by simply unscrewing and removing the nut G and
lifting up the cross bar F with the weight E on it. The piston B may be packed
with a leather ring, or in any other suitable manner. In the drawing it is shown
with a cup leather packing H but the joint between the outside of the piston and
the cylinder wall may be made in any other suitable way.
The cylinder A is connected with the oil tanks or barrels by means of a pipe I
having a suitable valve or cock J under the control of those in charge.
Orifices K L are made in the starboard, and port bows M N of the vessel about
two or three feet below the load line, and the oil is led from the cylinder A to these
orifices by means of pipes P Q controlled by valves R S; the bottom of the
cylinder A being provided with a small opening T out of which the oil can flow to
pipe O. It may be here observed that we lay special stress on the fact that the
orifices K L of the vessel (or other body or place where the apparatus is applied)
should be some distance below the load line, that is to say, the orifices should dip
into or enter the water below its surface so that the oil will not be carried away by
the wind from the bows of the vessel (or other part to be protected) as otherwise
it might be.
The mode of action is as follows:-
To fill the cylinder A with oil, the valve J in the feed pipe is opened, the
piston B is raised to the top of the cylinder, and the oil flows or is drawn from the
tanks (or other reservoir where it is stored) into the cylinder A. The feed
pipe I is now closed and the weight E is put on the top of the piston B, thereby
compressing the oil in the cylinder ready to force it out through the orifices Ki
when the valves are opened.
When it is desired to subdue the waves, the said valve or valves R S on the
exit pipe are opened and the oil flows out through the orifices K L on the star-
board or port side of the bow.
If desired, several ejection orifices may be provided on each side of the vessel.
The cover of the cylinder A is perforated, as shown in Figure 1 of the drawing
allowing the air to have access to the cylinder above the piston as the latte
descends, or to escape therefrom as the piston is raised.
The arrangement of the apparatus for harbour piers, or other situations, being
substantially similar to the above, does not require separate description.

page_text: 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. A wave subduer, composed of a reservoir of oil under pressure, and pipes
leading to exits a little below the surface of the sea, and, in ships, preferably near
the bows, whereby the oil is applied just where it is wanted and is introduced
to the water in a way that prevents or greatly lessens the danger of its being
blown away.
2. The herein described combined arrangement of parts forming our improved
apparatus for subduing the waves, substantially as described.
