Utilizing Sea Water, and also the Rise and Fall of the Tides, for a
Motive Power.
WALTER HORNE, Surveyor 12 Chapel Road Worthing 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 :-
In low laying lands adjoining the coast and particularly where the land is below
ordinary high water mark-two reservoirs to be formed on the land, side of the
bank, which usually keeps out the sea, the bottom of one reservoir (for the purpose
of description to be named A) to be at about ordinary low water level, and the
bottom of the other reservoir (for the purpose of description to be named B) to be
at a level about half way between, ordinary high, and low water marks a pipe to
be laid through the bank above referred to from the bottom of the reservoir A to
a point at or near ordinary low water mark on the fore shore in this pipe at a point
inside or to the land side of the bank-to be fixed a turbine, screw, wheel or other
engine, so constructed, that the same will revolve when water passes through the
pipe-either inwards or outwards, a shaft to be in connection with the same, in
order that the motive power thus attained may be used at the reservoir end of the
pipe a sluice valve to be fixed so as to regulate the flow of water either into or out
of the reservoir A-the reservoir A to be larger in capacity than the pipe above
referred to is capable of discharging therefore the head of water in the sea will be
constantly greater than that in the reservoir A whilst the tide is rising thus causing
the turbine, wheel, or screw to revolve quicker from the pipe referred to, at a point
between the turbine &c.-and the sluice valve, a junction to be inserted and a pipe
conveyed from the same to, and connected with the bottom of the reservoir B which
is at a higher level where a sluice valve will be fixed so as to govern the quantity
of water which passes through the turbine-therefore the water may, by the two
sluice valves be admitted to, or released from, the reservoirs A & B, through
the turbine at will-a connection of any description to be made between the
reservoirs A & B in order that water may be admitted from one to the other-at
high water, it will be found that the reservoir A is not full the pipe not being
sufficiently large to fill it, a large pipe or trunk to be constructed at a level a little
below ordinary high water mark, to convey a large volume of water to fill up to
sea level both reservoirs A and B this pipe or trunk to have a sluice to regulate
such inlet of water thus at high water time the water in the reservoirs being equal
in height to the sea outside, the turbine wheel or screw will be for some time
stationary when the tide drops the water to be let out of reservoir A. and the
pipe not being of sufficient capacity to carry the water from the reservoir as the
tide falls the water in the reservoir will keep a higher head than the sea, and will
leave sufficient water in reservoir A to keep the turbine &c. running during the
whole time of low water and until the tide rises to the level of the pipe, when the
valve from reservoir A will be closed, and the valve from reservoir B, opened thus
admitting the water from the higher level which will drive the turbine wheel or
screw until the tide has risen to a sufficient height above the pipe as to be admitted
into reservoir A. when it will be so admitted thus the turbine wheel or screw will
only be stationary for a short time at high water-this to be repeated at every
tide, or at will.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
I

page_text: 2. No cost of engines or cost of coal, engineers &c. will be required to work the
same.
3. That the same is my own invention and that the same may be applied
anywhere along the coast where the land is of little or no value, and may be made
of great value and various industries introduced into such neighbourhoods.
Dated this 20th day of March 1891.
