Improvements in Vessels Constructed to Convey Liquid such as
Petroleum.
We, MARCUS SAMUEL of 20 Portland Place, London, Merchant, and Alderman
of the City of London, and JAMES FORTESCUE-FLANNERY of 9 Fenchurch
Street, in the City of London, Member of the Institution of Civil Engineers and of
the Institution of Naval Architects, do hereby declare the nature of this invention
to be as follows:-
Steamers constructed with compartments forming tanks for the conveyance of
liquid such as petroleum have heretofore usually been worked at considerable
disadvantage owing to the tanks not being adapted for the conveyance of general
cargo so that it has been customary after conveying a cargo of petroleum to make
the return voyage in ballast, water being for this purpose placed in the tanks.
Now the object of this invention is to obviate the serious loss resulting from this
state of things by adapting the tanks for use either to convey liquid such as
petroleum in bulk or other cargo according to requirement. For this purpose
according to this invention the bottoms of the tanks are constructed to receive and
are provided with " ceilings "made in sections and fitted in hatches or otherwise
adapted to be readily placed in position when it is desired to carry general cargo
and to be readily removed and conveniently stowed when the tanks are to be used
for conveyance of liquid.

COMPLETE SPECIFICATION.
Improvements in Vessels Constructed to Convey Liquid such as
Petroleum.
We, MARCUS SAMUEL of 20 Portland Place, London, Merchant and Alderman
of the City of London, and JAMES FORTESCUE-FLANNERY of 9 Fenchurch
Street, in the City of London, Member of the Institution of Civil Engineers and of
the Institution of Naval Architects, 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:-
Steamers constructed with compartments forming tanks for the conveyance of
liquid such as petroleun have heretofore usually been worked at considerable
disadvantage owing to the tanks not being adapted for the conveyance of general
cargo so that it has been customary after conveying a cargo of petroleum to make
the return voyage in ballast, water being for this purpose placed in the tanks.
Now the object of this invention is to obviate the serious loss resulting from this
state of things by adapting the tanks for use either to convey liquid such as
petroleum in bulk or other cargo according to requirement. For this purpose
according to this invention the bottoms of the tanks are constructed to receive and
are provided with "ceilings" made in sections and fitted in batches or otherwise
adapted to be readily placed in position when it is desired to carry general cargo
and to be readily removed and conveniently stowed when the tanks are to be used

page_text: for the conveyance of liquid, as we will now proceed to describe by aid of the
accompanying drawings, in which
Fig. 1 is a vertical cross section; and
Fig. 2 is a horizontal section of a portion of a vessel of the kind referred to
constructed according to this invention.
At the bottom of each tank are a number of hatchies formed by and between the
transverse plates 1, the keelson 2 and the intercostal. keelsons 3, to the
upper ends
of which parts are secured the angle irons 4, 4, 4 the whole forming in conjunction
with supplementary transverse angle irons 4, a skeleton floor to carry the removable
ceiling. The ceilings, one only of which is shewn in the drawings, are each com-
posed of a number of removable sections 5, 5, 5 that are fitted into the said
hatches as shewn and are supported at the ends by the upper flanges of the transverse
angle irons 4, 4 and the upper edges of the transverse plates 1, and some of which
are also further supported at one side by the lower flanges of the longitudinal angle
irons 4 4 as shewn.
By this construction it will be seen that the ceilings, which may be composed of
wood as shewn, can be readily placed in position or removed and stowed, according
as the tanks are to be used for the conveyance of general cargo, or liquid
in bulk.
The skeleton floor and removable ceiling may at the outer portion be of curved
form, as seen in transverse section, in Fig. 1, or the whole of the floor may be made
flat as shewn in vertical cross section in Fig. 3 for which purpose the upper edge
of the transverse plates 1 and the angle irons 4, 4° are made straight throughout
their length as shewn.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
claim is :-
A vessel constructed to convey liquid such as petroleum in bulk, in which the
bottoms of the tanks are constructed substantially in the manner described and
shewn with ceilings" made in sections adapted to be readily placed in position
when it is desired to carry general cargo and to be readily removed when the tanks
are to be used for the conveyance of liquid in bulk as set forth.
