I WILLIAM COPPIN of No. 23 Dulwich Road Herne Hill in the County of Surrey
Engineer and Marine Architect do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in boats and apparatus for fishing.
I employ for this purpose a vessel similar to a steam launch and to attract fish I
provide for the exhibition of electric light downwards into the water.
The electric current is derived from a dynamo driven by an engine receiving steam
from the boilors which supply the propelling engines.
In the fore part of the vessel I provide a light compartment which I separate from
the rest of the vessel by water tight bulkheads rising above the water level.
Within this compartment I provide two holes in the bottom of the vessel one on
either side of the keel and these I glaze with thick clear glass strong enough to safely
support the water pressure. Immediately over the glazed aperture I provide electric
lanthorns lighted preferably with incandescent lamps as these are more easily managed
at sea than arc lamps. Over the lamps I provide reflectors which throw the light
downwards. I provide for replacing the glasses at sea in case of breakage by having
slides or doors to close the apertures whilst a new glass is put in.
Breakage of the glass will not be attended with any risk to the vessel as it is only
the small light compartment into which the water can enter.
This vessel can be used in fishing in different ways-one way is to lay out a floating
net and then decoy the fish into it by running the vessel over the net where provision
is made to allow her to pass without injury to the gear.
It is also possible to secure the fish following the light with hand nets similar to
landing nets.

I, WILLIAM COPPIN of No. 23 Dulwich Road, Herne Hill, in the County of Surrey,
Engineer and Marine Architect, 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 has for its object improvements in boats and apparatus for fishing.
I employ for this purpose a vessel similar to a steam launch and to attract fish I
provide for the exhibition of electric light downwards into the water.
The electric current is derived from a dynamo driven by an engine receiving steam
from the boilers which supply the propelling engines.
In the fore part of the vessel I provide a light compartment which I separate from
the rest of the vessel by water tight bulkheads rising above the water level.
Within this compartment I provide two holes in the bottom of the vessel one on
either side of the keel and these I glaze with thick clear glass strong enough to safely
support the water pressure. Immediately over the glazed aperture 1 provide electric
lanthorns lighted preferably with incandescent lamps as these are more easily managed
at sea than are lamps. Over the lamps I provide reflectors which throw the light
downwards. I provide for replacing the glasses at sea in case of breakage by having
slides or doors to close the apertures whilst a new glass is put in.
Breakage of the glass will not be attended with any risk to the vessel as it is only
the small light compartment into which the water can enter.
This vessel can be used in fishing in different ways-one way is to lay out a floating
net and then decoy the fish into it by running the vessel over the net where provision
is made to allow her to pass without injury to the gear.
It is also possible to secure the fish following the light with hand nets similar
to landing nets.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan, Figure 2 is a side elevation and Figure 3 is a transverse section
of a steam fishing boat fitted in accordance with my invention.
a and bare two transverse water tight bulk heads rising to the level of the deck;
they enclose the light chamber between them, e is another bulk head dividing the
light chamber amidships into two parts. dd are windows glazed with stout glass
which may if desired be somewhat convex to control the divergence of the beam of
light. ee are shutters closing water tight over the windows and capable of being
closed from the outside. They serve to protect the glass when not in use and in case
of the window being broken to close the aperture. Just within each window an
incandescent electric lamp is provided and behind this a silvered reflector f. The

page_text: electric lamps receive their current from a dynamo driven by a small engine in the
engine room. Or the electricity may be generated by a battery as is well understood.
In place of electric light I may use light from other sources as from a petroleum or
other lamp.
My invention is applicable in part to sailing vessels and row boats which may be
provided with light compartments and lights as herein described.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. A fishing boat having bulkheads enclosing a light compartment with a window
or windows below water line and with a light or lights exposed at such window or
windows substantially as described.
2. A fishing boat fitted with a screw propellor and having bulk heads enclosing
a light compartment with a window. or windows below water line and provided with a
dynamo driven as described and supplying current to electric lamps exposed at the
windows substantially as described.
