Improvements in Fishing Craft.
RICHARD SIMPSON St. Andrew's Dock Hull Smack owner and Fish salesman
and SAMUEL PUPLETT 5 Thornbury Road Clapham Surrey Engineer do hereby
declare the nature of this invention to be as follows:-
It is well known that all descriptions of fish deteriorate in quality-some kinds
more quickly than others-directly life is extinct and to prevent this deterioration of
quality certain fishing craft have been fitted up with wells or tanks in which the
fish are placed as soon as caught, with a view of keeping them alive until port is
reached.
These craft have perforations through the hull to allow the water to pass freely in
and out with the motion of the boat.
Such well boats have answered to a certain extent the desired purpose when the
port at which the fish is landed is near the open sea, but when the port is situated far
up a river as at Hull or London for example the river water is fatal to the fish and
but few survive and those are depreciated in quality.
To overcome this difficulty and to keep the fish alive as long as required we
construct wells or tanks in our craft in such a manner that by opening a valve or
valves, which may be placed at or near the stern of the craft, and other valves which
may be placed forward, a current of water is allowed to flow from the sea through
the wells or tanks and by this means the water is constantly changed and kept from
becoming foul-before the craft leaves the open sea and enters a river or other
contaminated waters the beforementioned valves are closed, the tanks being then full
of the water out of which the fish was taken and which is thereby shut off from
contamination by other water.
We force into the water contained in the wells or tanks a measured quantity of air
and we also maintain an artificial circulation in the wells or tanks, by means of
pumps or other convenient arrangements, and apparatus.
Dated this 15th day of June 1889.

Improvements in Fishing Craft.
RICHARD SIMPSON St. Andrew's Dock Hull Smack owner and SAMUEL PUPLETT
5 Thornbury Road Clapham S.W. Engineer 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 :-
Our Improvements relate particularly to Steam Fishing Craft which are fitted up
with wells or tanks in which the fish are placed as soon as caught with a view of
keeping them alive as long as required. For this purpose we employ apparatus which
we shall describe referring to the accompanying drawings in which like letters of
reference indicate corresponding parts.
Fig. 1 sheet 1 is a sectional elevation of a Steam Fishing Smack fitted up in
accordance with our invention.
Fig. 2 sheet 1 is a plan of the same.
A is the fish well or tank. B & B¹ are two pipes communicating with the sea by
means of sea cock or valves C & C fixed on the sides of the craft at the bow below
the water line. D and D¹ are retaining or non-return valves fixed in any convenient
position in the pipes B & B¹ and which prevent the water from returning from the
וני_מד

page_text: well A. E is a pipe passing from the well A aft through the side of the craft in
front of and in proximity to the propelior H, and is provided with a sea cock or
valve F. fixed on the aft bulkhead over the stern gland. G is a pipe connected to
the donkey pump I. K & K are discharge pipes which may be perforated- and
which we fix at any convenient height above the water level in the well at the forepart
we cause the water to fall from these pipes into the well in the form of spray and it
thereby is re-oxigenized and purified.
In carrying out our invention the well A may be of any convenient form and may
either be entirely or only partially covered in.
In the operation of our invention the progress of the craft through the water forces
a stream through the pipes B and B into the well A the motion of the screw or
propellor H. creates a partial vacuum in the pipe E and thereby induces a flow of
water from the well A-we make the pipe E of such proportions that it will pass as
much water as is admitted by both the pipes and Bi and we thus establish a free
circulation the speed of which can be regulated by means of the sea cock F. and the
water in the well changed as often as desired.. By closing the sea cocks or valves ()
and C and F. the admission of water to the well can be prevented and by means of
the pump I and the pipes G. K and K¹ a circulation of the water in the well can be
maintained. Intake valves for filling the tanks or wells of vessels are not novel and
form the subject matter of various patents for example 1526385 and these we do not
claim per se.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we
claim is
In steam fishing craft fitted up with wells or tanks in which the fish are placed
as soon as caught with a view of keeping them alive the method of obtaining a
circulation of water through the wells or tanks by means of the way on the craft
and the partial vacuum caused by the propellor, in combination with the pipes E
and B and B and the sea cock or valve F and also the circulation of the water in
the well by means of the donkey pump and the spray pipes K and K' substantially
as described and shewn.
Dated this 28th day of February 1890.
