PROVISIONAL SPECIFICATION.
Improvements relating to the Distribution of Oll on the Sea from
Fishing Boats and other Small Craft.
We, SAMUEL ROBINSON, of 18 St. John's Road, Gravesend, in the County of Kent,
Mariner, and HENRY WILLIAM PERRY, of Cleethorp Road, Grimsby, in the County
of Lincoln, Mariner, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide small craft such as the boats of fishing
smacks, with means for distributing oil on the sea to cause the same to roll easily
and quietly under the craft, and thus obviate the loss of life by overturning or
"staving in of the sides, which frequently happens when the seamen in the boats
are attending to the fish cutters, or are otherwise engaged.
"
According to this invention we place a suitable oil tank or reservoir in the bottom
of the boat, near the stern and lead two or more pipes therefrom discharging the
oil by gravity into the sea through the stern of the boat. Taps or cocks are fitted to
the pipes, at a convenient spot for manipulation, so as to regulate the discharge of
the oil therefrom. The tank or reservoir is surrounded by an annular chamber or
Jacket, into which hot water or steam is passed during cold weather to prevent the
oil from congealing, cold water being placed in the jacket during hot weather to
prevent the evaporisation of the oil.

Improvements relating to the Distribution of Oil on the Sea from
Fishing Boats and other Small Craft.
We, SAMUEL ROBINSON, of 18 St. John's Road, Gravesend, in the County of
Kent, Mariner, and HENRY WILLIAM PERRY, of Cleethorp Road, Grimsby, in the
County of Lincoln, Mariner, 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 :-
The object of this invention is to provide small craft such as the boats of fishing
smacks, with means for distributing oil on the sea to cause the same to roll easily
and quickly under the craft, and thus obviate the loss of life by overturning or
staving in of the sides which frequently happens when the seamen in the boats
are attending to the fish cutters or are otherwise engaged.

"
According to this invention we place a suitable oil tank or reservoir in the stern
of the boat, and lead two or more pipes therefrom discharging the oil by gravity
into the sea through the stern of the boat. Taps or cocks are fitted to the pipes,
at a convenient spot for manipulation, so as to regulate the discharge of the oil
therefrom. The tank or reservoir is surrounded by an annular chamber or jacket,
into which hot water or steam is passed during cold weather to prevent the oil from
congealing, cold water, ice, or a freezing mixture being placed in the jacket during
hot weather to prevent the vaporisation of the oil.
And in order that our invention may be more fully understood and carried into
practice, we will now proceed to describe the same with reference to the
accompanying drawings, in which similar letters indicate corresponding parts
throughout.

page_text: Figure 1 is an elevation of our oil tank or reservoir; Figure 2 is a sectional
elevation on the line A B Figure 1 ; Figure 3 is a sectional elevation on the line CD
Figure 2 and Figure 4 is an elevation of the stern of a boat with our invention
fitted thereto.
E is the receptacle for the oil, and F' is the annular chamber or jacket. The oil
receptacle E is replenished when desired through an aperture G in the top, on to
- which screws, a .cap H provided with an air vent or vents to maintain the air
pressure on the surface of the oil, and cause it to flow through the taps or cocks J
when they are opened. These taps J are provided with unions.L by, means, of which
they may be readily affixed to and detached from the horizontal ends of the right
angled tubes K rigidly fixed to the stern of the boat. The horizontal ends of the
said tubes K pass through apertures specially made in the stern of the boat and their
vertical ends lie close up to and against the stern as shewn in Figure 4, so that
they may not easily be knocked off by an accidental knock or blow. The horizontal
ends of the said tubes K are screwed to correspond with the threads on the unions L
and on, the ends of the taps or cocks J By this arrangement the jacketed oil tank
or reservoir may be readily removed from or placed in the boat as required, the
right angled tubes K being of course immoveable.
The annular chamber or jacket F is provided with a screw capped aperture M for
replenishing and also with a tap or cock N to carry off water when it is desired to
empty the said chamber or jacket.
In the drawings, we have shewn a simple form of jacketed oil tank or reservoir,
but we do not confine ourselves to the shape shewn, which will in all cases be made
to conform to the shape or configuration of the stern of the boat or other craft to
which it is to be applied, nor do we confine ourselves to the mere details of our
invention, such as the position of the taps or cocks etc., as they are obviously
capable of considerable modification without departing from the essence of our
invention.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim 18:-
(1) An oil reservoir E provided with an annular chamber or jacket F with taps
or cocks J with unions L to be screwed into a corresponding number of angled
tubes K passing through, and rigidly affixed to, the stern of the boat for discharging
the oil from the reservoir E, substantially as and for the purpose 'hereinbefore set
forth and illustrated.
(2) In a boat carrying an oil reservoir or tank, provided with discharging taps or
cocks and unions, the use of angled tubes K passing through and rigidly affixed to
the stern of the boat substantially as described and illustrated in Figure 4 of the
accompanying-drawings.
