COMPLETE SPECIFICATION.
Improvements in Sea-calming Apparatus.
I, AUGUST JOACHIM SCHJÖTT of Bergen, Norway, Rope Manufacturer, 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 consists in applying a fixed oil tank to the boat or vessel itself and
to provide in connection therewith pipes for causing the oil to flow out into the sea
in such manner as to distribute it in the most advantageous manner as required.
The tank may be placed in any suitable part of the vessel or boat and is provided
with a valve of any suitable construction in or at the bottom. This valve is arranged
to be opened and closed more or less by means of a lever, handle, screw and hand-
wheel or other suitable well known appliance. The valve admits oil to a pipe or
pipes fixed along the sides of the vessel or boat and provided with perforations for
the oil to issue through same. By suitably arranged pipe and valve connections
the oil may in some cases be distributed more or less towards the bow the sides or
the stern or to one side or the other as the case may require.
In the accompanying drawings I have shown the invention applied to a large
boat
Figure 1 being a side view.
Figure 2 a part plan showing the tank applied in the bow end of the boat and
Figure 3 a sectional side view of same.
Figure 4 is an enlarged side view of the tank and valve the latter being in the
closed position.
Figure 5 a side view of the valve in the full open position,
Figure 6 a vertical section of same and
Figure 7 a plan section.
Figure 8 is a vertical cross section of an apparatus suitable for a small boat.
I only give these forms of valve as suitable examples but many other valve con-
constructions will answer the purpose.
The oil tank A is in Figures 1. 2 and 3 shewn fixed in the bow end of the boat
as high up as convenient so as to afford suitable head or pressure. A' is an air
tight fitting lid which covers a filling opening. The valve B consists of an outer and
an inner part which latter by a flange is fixed to the bottom of the tank and by four
screwed bolts with nuts also stayed to the top of the tank. The inner part has four
lateral openings B. To the outer part of the valve attached a rod B² the upper
end of the which is screw threaded and passes through a nut C fixed on the top of
the tank. The screw thread has a narrow length groove whereby air is admitted
when the valve is opened so as to allow the oil to flow out freely.
By means of the hand wheel B³ fixed in the valve rod B the valve can be raised
and lowered as required. The oil flows from the valve into the pipe D which in
this example branches off to each side and supplies oil to the fore end of a pipe E
fixed in this case under a strake so as not to protrude or be materially in the way.
The pipe E is provided with small holes for the oil to issue upon the water. There
may be two or three such pipes, say for instance one for supplying oil to the
water at the fore end of the boat, one in the midde, and one near the stern, and by
suitable pipes and valves inboard. I may then admit oil to any or all of them
according to the state of the sea and course of the boat. In Figure 8 the tank A is
provided with a valve B of ordinary form having a lead washer B* for making joint
with the valve seat which latter may be screwed for easy removal. The necessary air
for replacing the space taken up by the oil as it flows out of the tank is supplied by
a fine tube Ax in the filling lid A¹.

page_text: If, instead of the hand wheel and screwed part of the rod B2, 1 apply a lever to
a plain valve rod, I may impart a sort of pumping action to the valve and thereby
force out the oil as may sometimes be required for clearing the pipes and in cases of
emergency.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A sea calming apparatus consisting of a closed oil tank fixed in the vessel, a
pipe fixed along each outer side of the vessel provided with a number of holes, and
suitable valve and pipe connection. between the tank and the perforated pipes for
regulating the issue of the oil from the perforations direct upon the sea substantially
as set forth.
2. A sea calming apparatus consisting of a closed oil tank fixed in the vessel, and
provided with a regulating oil outlet valve and with means for air supply to permit
the oil to flow out freely, a pipe fixed along each outer side of the vessel provided
with a number of holes, and suitable pipe connections between the outlet side of the
valve and the perforated pipes. substantially as and for the purpose set forth.
3. In a sea calming apparatus a closed oil tank fixed in the bow of the vessel and
provided with a bottom outlet regulating valve operated by a hand wheel on a
screwed spindle passing through a nut fixed to the tank and provided with a small.
air supply pipe passing through a screwed filling lid in combination with perforated
pipes fixed to the outer sides of the vessel and with intermediate pipes between the
said valve and the said perforated pipes substantially as and for the purpose set
forth.
4. The construction of sea calming apparatus shown in the drawings.
