This invention has for its object a novel arrangement of apparatus by which the rise
and fall of the tide may be made available to raise sea or other water into an elevated
reservoir for the supply of baths for street watering, for flushing sewers and for other
purposes.
I provide a reservoir in such a position that it fills at high water. I also provide a
float in a convenient enclosure constantly open to the tidal water. I mount on the
float an hydraulic ram or like apparatus. I lead a flexible or jointed pipe from the
reservoir to the hydraulic ram and another pipe I lead from the ram to the elevated
reservoir. As the tide falls the water descends from the lower reservoir to the ram
and when the current attains a certain velocity it carries a valve up to its seat and
the flow is thereby suddenly checked. The momentum of the water in movement is
then expended in raising water to the elevated reservoir. The valve afterwards falls
away from the seat and the operation is repeated and so on continuously until the tide
again rises or the water in the lower reservoir is all expended.
The hydraulic ram being carried upon the float the waste water is always delivered
at the lowest available level.
Sometimes I employ steam to raise the water; I then dispense with the lower
reservoir but retain the tidal float.
On the float I mount an aquapult or like apparatus by which a jet of steam is
applied to propel water up through a rising pipe into the elevated reservoir.
The aquapult or like apparatus being carried by the float always remains at the
same distance from the surface of the water and the dist: nee is that at which the
apparatus works most efficiently.

such pipe delivers the water propelled forwards by the aquapult or apparatus into the

maintained.

Improvements in Apparatus for Raising Water for the Supply of
Public or Private Baths, Street Watering, Flushing Sewers, and
other Purposes.
I, WILLIAM GREEN, of Ramsgate, Alderman, 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 a novel arrangement of apparatus by which the
rise and fall of the tide may be made available to raise sea or other water into an
elevated reservoir for the supply of baths, for street watering, for flushing sewers and
for other purposes.
I provide a reservoir in such a position that it fills at high water.
I also provide a
floating stage or pontoon in a convenient enclosure or basin constantly open to the
tidal water. I mount on the float an hydraulic ram or a series of such rams or like
apparatus. The number of the machines on each float or stage will depend upon the
rise and fall of the tide and the supply of water required.
In some cases there will be a rise and fall of over twenty feet in which case the tidal
force will be available during nearly the whole period of the fall. In other cases such
tidal force is only available for a few hours during each fall. In such latter case I
prefer to use a series of machines capable of allowing nearly the whole of the stored
water to pass therethrough and so become available as a source of lifting power at
each fall. There are several varieties of rams or similar machines suitable for this
purpose. There are also other machines or apparatus of a like character such for
example as the turbine suitable for the purposes of this invention. Whatever the
machine or apparatus employed I load a flexible or jointed pipe from the reservoir or
from the tanks connected therewith as hereinafter described to each hydraulic ram or
other machine and another pipe from such machine or apparatus to the elevated

page_text: reservoir. The store or lower reservoir has a portion of its space divided from the
main portion for the purpose of feeding the rams or other apparatus at as nearly as
possible an uniform level. When the tide has fallen a few feet-say for example
about five feet the float or floating stage bearing the machines will sink to the same
extent and the pressure of water from the store reservoir will then begin to exert its
power and, a portion of the water entering such rains or similar apparatus will be
raised to the elevated or upper reservoir either by direct action or by means of a
pump or pumps worked by the power thus obtained. As the tide falls the water
descends from the lower or store reservoir or from tho tanks connected therewith to
the ram or other apparatus on the float and in the case of a ram being employed
when the current attains a certain velocity it carries a valve up to its seat and the
flow is thereby suddenly checked. The momentum of the water in movement is then
expended in raising water to the elevated reservoir. The valve afterwards falls away
from the seat and the operation is repeated and so on continuously until the tide again
rises or the water in the lower reservoir is all expended.
The drawing will show how this invention may be carried into effect. A represents
the lower or store reservoir which may be of any desired capacity. This is enclosed
by lock gates communicating with a channel leading to low water level. When the
tide is at its height the gates are closed so as to retain all the water stored therein.
B is a basin constantly open to the tidal water but having gates to be used if so
desired to regulate the full of water therein as the tide falls. C is a float or stage
bearing the rams or other apparatus. D D is a supply tank divided into sections and
communicating direct with the lower reservoir by means of openings at the lower part.
In order to keep the water at an uniform level with that in the lower reservoir AI
employ apparatus like or of an equivalent character to that shown in the drawing in
which E E are double jibs containing pulleys over which chains pass bearing
weights F F, also weighted buoys G G. As soon as the water in the basin has fallen
sufficiently the water in the tanks D D will begin to work the rams or other machines
and as it falls both in the tanks and the lower reservoir the weighted buoys G G will
also fall thereby lifting the weights H H. These in their turn will cause the weights I I
to exert pressure on the sliding valves J J and by so doing will keep the outlet
pipes K K at the same level as the water in the store reservoir. This automatic action
will continue until all the water in such reservoir, is expended. As the tide again
rises the weighted buoys will also rise causing the weights H H to descend and the
sliding valves to rise. This will be repeated with each rise and fall of the tide. The
sliding valves pass through stuffing boxes placed a little above the bottom of the tanks
and into chambers sunk in the ground. When turbines are used for the purposes of
this invention the pumps connected therewith are to be arranged either on the floating
stage or on the walls of tho basin. By using a series of rams, turbines or similar
apparatus at the same time as described the water stored in the lower reservoir exerts
its full power in the smallest time with a maximum effect. For example:-
assuming that the lower reservoir has an area of twenty acres and the rise and fall of
the tide be from twelve to fourteen feet the sixteen turbines shewn on the float will each
be capable of raising to a height of 100 feet about sixteen thousand gallons per hour
with an average fall of seven feet each tide or about three million gallons a day in the
two tides. The hydraulic rams or other apparatus being carried upon the floating
stage the waste water is always delivered at the lowest available level.
Sometimes I employ steam to raise the water, 1 then dispense with the lower
reservoir but retain the tidal float.
On the float I mount an aquapult or like apparatus by which a jet of steam is
applied to propel water up through a rising pipe into the elevated reservoir. The
aquapult or like apparatus being carried by the float always remains at the same
distance from the surface of the water and the distance is that at which the apparatus
works most efficiently. A flexible pipe conveys the steam to the aquapult or like
apparatus and another such pipe delivers the water propelled forwards by the aquapult
or apparatus into the rising main. The apparatus continues to act automatically so
ong as the supply of steam to it is maintained.
