Water through the Vessel, or Parts of the same, or Cisterns
therein.
We, "TRANSPORTAKTIEBOLAGET FÖR LEFVANDE FISK
"of Thurenas pr.
Billeberga, Sweden 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 refers to an improvement of and a supplement to the invention
forming the object of the English Patent No. 8051 of 1892 concerning renewal of
water in vessels for carrying fish.
In the accompanying drawings is shown schematically a vessel fitted with a
cistern k, known from the said Patent No. 8051 of 1892, the upper edge of which
is below the waterline b, and which is provided with a raised structure o (which
may extend entirely up to and be built together with the deck of the vessel if
desired). Said cistern may be divided by means of one or more watertight
partition-walls, that extend above the waterline b, with the view of preventing
the water in the raised chamber from flowing from astern and forward or
vice versa, when in a rough sea. One or more tubes s² directed forward from the
cisterns kopen in the prow; said tubes may also be arranged otherwise and on
other place or built together with the vessel itself, for instance be located in the
keel &c., provided only that they are directed forward.
The tube may, if desirable, be fitted with a strainer or filter and with a
perforated lengthening tube or cap in the interior of the cistern for the distribution
of the water.
When the vessel advances by means of its steam or sail power, water enters in
the cistern k through the tubes and rises until it passes over the partition wall x,
in order to find its issue through the tubes 2 directed astern (or through outlets
arranged in some other way), after having flowed through the partitions of the
cistern from below and upward and vice versa. In or over the openings in these
tubes the self acting inlet and outlet valves described in the Patent 8051 of 1892
may be fitted, The partition wall x may extend up to the upper edge of the
raised chamber o and be provided with a self acting valve opening backward
placed for instance in the waterline b.
When the prow of the vessel descends in the waves the self acting inlet valve
in opens, water flows into the first part of the cistern, continues through the self
acting valve in the partition wall to the rear part of the cistern k, and when the
aft part rises it passes away through the self acting valve of the tube opening
outward, or through outlets arranged in some other place. The inlet tubes may
be, if desired, fitted with stop valves for regulating the flow of water, and for
enabling the cistern to be emptied in order to use it as a hold for dry goods. The
tubes may also be differently arranged, for instance in such a manner that the

page_text: one opens in the foremost part and the other in the aftermost part of the cistern k,
and in each of said parts outlets are suitably placed and arranged.
The inlets may also be placed at a higher level and the outlets at a lower and
vice versa.
If the cistern is located in the prow of the vessel no tubes but only openings are
used.
If openings are made at the crest of the wave fore, and in the depression of
the wave just behind, the water will in this case, if for instance a steamer advances
in a calm sea, enter through the opening st, rise to the same level in the cistern p,
divided by the watertight bulkhead a, as before the prow, and find its outlet
through the opening 13.
The openings may be fitted with self acting inlet and outlet valves, intended
for sea.
If the cistern is located more astern the outlet of the water may take place
through openings without tubes and with or without self acting valves, besides it is
indifferent, where the openings are located.
When the vessel is still the surface water is discharged by pumping in such a
manner that the fresh water enters through the inlets.
Instead of any of the circulating arrangements above described which we do
not claim, a propeller is provided, for instance in the wall or at some other
suitable place, said propeller is operated by hand, or for instance by clockwork
or by special motor. In rotating it sends water from the foremost cistern to the
aftermost, fresh water thus entering through the inlets to pass away successively
through the outlets.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
To produce a flow of water through a vessel by help of a propeller, substantially
as set forth.
