REES EVANS 18 Scarboro' Street West, Hartlepool Merchant do hereby declare
the nature of this invention to be as follows:
My invention having for its object the increasing of speed of ships, preferably
steamships and the consequent saving of power; as compared with the ordinary
system and consists in so building and configuring ships that there shall be a
channel or channels running parallel with the keel in the and thro the centre of the
vessel from stem to stern such channel or channels being either round, oval, square
or other configuration provided there is room for the placing of such channels at
the centre or alongside the keel through the centre of vessel, so as to enable one two
or more propellers to be used in the channel or channels for the propulsion of
vessel, such propellers being driven by steam engine or other motive power and such
channels forming water guide to and from propellers from stem to stern.
It is intended that the propellers shall be placed in this or these channels, or
waterways, such waterways being either straight, concave, convex, or any other
shape or form, so as to allow of large or small propeller and with large or small
channel orifices at entrance and discharge.

I REES EVANS of 18 Scarborough Street West Hartlepool in the County of
Durham, Merchant 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 :-
My invention has for its object the increasing of speed of ships preferably steam
or other power ships and the consequent saving of power, as compared with the
ordinary system, and it consists in so building and configuring ships, that there
shall be a channel or channels running in and through the centre of the vessel from
stem, to stern or any portion of the vessel, such channel or channels being either
round, oval, square or other configuration so as to enable one two, or more
propellers to be used in such channel or channels, such propellers being driven by
steam engines or other motive power, and such channels forming water guides to and
from propellers from stem to stern. It is intended the propellers shall be placed in
this or those channels or waterways, at such point as is most convenient, the water-
ways being straight, concave, convex, or any other shape or formn longitudinally so
as to allow large or small diameter propellers to be used and with enlarged or
diminished orifices at entrance and discharge.
