Civil Engineer do hereby declare the nature of this invention to be as follows:-
See Drawing where Figs. Nos. 1 and 2 show the arrangement in Vertical and
horizontal Sections respectively. A is the large storage tank, (which may be formed
of slate, timber or galvanized iron): B the receiving and filtering vessel, attached to
the underside of the cover of A: B is the filter within B C is the usual pipe from
rose head" pipe E that
the roof: 1) is a swan neck pipe resting on the top of the
carries a perforated plate F: D is secured to C by the pin shown, but upon its being
taken out D can be raised to clear the flanges of E and taken out to clean F: at the
bottom of E (which enters B at its side) a small pipe G is supported at one end by E,
the other by H in which a slot is formed: H is carried by the lever J, having a
counter-balancing weight J2, the other side of the fulcrum at the bottom of Ha
conical rubber band H2 is secured, and on the inside of H at the bottom a ring H³ of
rubber or leather is secured: the long stem of a T piece K passes through H the cross
arms are bent down and carrie a ring of cork L, the cross arms of K pass through
slots in H from the top, near the lower end of K it carries a rubber collar that rests
upon H³ and forms a valve and supports K, the bottom of K passes through a guide
as shown: B3 is made of earthenware or china, it has an aperture (out of the centre)
formed in it as shown through which H passes and is arranged to allow a large space
on the side the pipe E enters B, B' has a lip on that side to prevent the water passing
directly from it over B: the filtering medium in B2 is to be composed of spongy iron,
or coke and sand and carbon and is kept in place by its cover: the pipe M passes
from B' through B to the bottom of A: the bottom of B is provided with the outlet
pipe N to act as a flushing out pipe and overflow.
A has an overflow at A' and is supported at the base by a ring of brick work with
taps for drinking, culinary, and flushing purposes: H. J &c are enclosed by the box
1

page_text: Thus the water entering at C is strained by F passes through B and N and goes to
waste, but a small portion enters G and passes down H, being stopped by the valve H³
and when it rises to 2 or 3 inches below the slots supporting G and K its weight
forces H down and H2 prevents any more from passing through N; the water then
rises in B and passes into the filter and through M to A, and as it continues to rise
in B. L floats, raises K and opens the valve H³ and lets the water in H go to waste
through N, then H also rises but as the water continues to rise in B it passes through
the slots into H and forces H down again (K being still upheld by L) and the over-
flow passes on through N. As the water is drawn off and sinks in B. upon its falling
to the level of the slots in H it ceases to flow into H and it empties itself, when H
and J2 causes H to assume and maintain the position shown on the Drawing, and as
the water continues to recede H³ is closed by K falling and is again ready for the first
water passing through C to go to waste through N. The coil O with an oil lamp is
provided to counteract frosts.

RORERT COOKE SAYER 3 Summer Hill Villas, Maindee, Newport Monmouthshire
Civil Engineer do hereby declare the nature of my invention for FILTERING AND
STORING RAIN WATER and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
See the Drawing attached where Fig. 1 shows the arrangement in Vertical Section
that is applicable to cold climates and the rain fall of a light intermittent nature.
:
A is the large storage tank which may be formed of slate, timber, galvanized iron,
or earthenware glazed socket pipes. B is the receiving vessel attached to the under-
side of the cover of A: B2 is the filter within B C is the usual pipe from the roof:
D is a swan-neck pipe resting on the top of the "rose head" pipe E (dotted) that
carries a perforated plate F: D is secured to C by the pin shown, but upon its being
taken out D can be raised above the flange of E and taken out to clean F: the bottom.
of E enters B. B³ is a box the top of which has a concave form and drains off to the
hole B, B3 contains a lever J that carries at its end the rod H and vessel H' which
has an overflow leading to the exterior: the bottom of H carries a large washer, and
below it passes through a guide, and the whole is balanced as required by means of
the weight J2 the other end of the lever. The fitter B has a projecting lip on top to
direct the flow from E clear of the filter cover and has two pipe connections M
(leading into A) which are made tight by means of rubber washers or cork plugs, at
the top they are plugged in with spongy iron or porous pumice or silica stone. B is
covered in by a perforated cover, and is divided vertically by the four discs that have
a portion of their side cut off alternately as shown, the spaces between which are filled
up as follows viz:-the top one with fine sand, the next with coarser sand, the next
with prepared granular animal and vegetable charcoal the next with coarse sand and
the bottom with similar charcoal except that round the plugs which is to be finer :
B2 has a centre chamber allowing the rod H to pass through it. N is an overflow
communicating with B: L is a ring of cork or other float supporting the rods K that
unite in one at K2 which carries a rubber valve at the bottom, and opens or closes the
aperture A which admits either to a drain below or a second (or more) storage tanks.
O is a coil pipe connected with the lamp 03 outside and carries a cowl O³ on top.
The whole is supported on the ring of brickwork Z.
The working will be as follows: the water coming down C, is partly filtered by
passing through F, it then enters B, is directed by the lip of B' to the side and passes
through to the overflow N. until sufficient rain has fallen upon the top of B* and gone
into Has to overbalance the weight J', which causes the valve at the bottom of H to
close the waste N, the water then rises in B and flows into B2 through its cover and
is directed through the filtering medium by the divisions as shown by the arrows
and passes into A through M. rising in A to the float L the valve at A' is opened

page_text: but closes again as the water is drawn off. The coil O is to keep it from freezing,
when heated by a lamp at 0³.
For tropical climates and others where the winters are not so severe, and the rain
fall is great in short periods the same principal is applied as shown in Fig. 2 where
the same figures refer to the same parts as before. It consists of a similar storage
reservoir, and where the heat is great it is to be covered in the cover is similarly
formed and has a similar base and valve the lever J works in a similar way: the
overflow from H2 goes direct into the overflow N. and the communicating pipe E
between E and N works with the lever J as shown in dotted lines, and the balance
weight J has an aperture in A opposite so that it may be adjusted without removing
the cover (a tray being formed as shown to prevent any extraneous liquid or other
being inadvertently inserted). The filtering medium is the same and occupies the
whole area of the section of the storage vessel A: a pair of holes ✗ are formed in A
at any one or all the strata of the filter so that upon drawing (the special) plug
provided, the water flowing through shall carry the medium above with it, which after
plugging again may be replaced through the opposite hole. The working will be as
follows: the water is received from E into E2 and passes off through N until H2 is
charged (by the rain from the cover) and causes E to take the dotted position, when
the water falls upon the filter cover and passes down as before the overflow from H
is carried off by the pipe attached (being raised up in it to the level required). In
both cases upon the rain ceasing the water in H2 is evaporated, when J2 returns E to
the original position ready for the next dirty water.
A tropical (or heavy) fall of rain that comes too rapidly for the filter to pass is
stored in that part of A above B². When the column forming A is high the straps Y
keep it secure to the adjoining house.
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
1st. The above mode of cleansing, gathering, filtering, and storing rain water which
is suitable to hot or cold climates, heavy tropical falls of rain or light and intermittent
falls, substantially as described.
2nd. The mode of letting the first fall of rain that passes over and cleanses the roofs
and is consequently dirty pass either to waste or to store for garden or other purposes,
while that which follows and is clean passes through the filter and is stored for drinking
purposes, substantially as described.
3rd. The construction of the filter which causes the water to traverse a great length
of the filtering medium backwards and forwards through varying strata, and the mode
of plugging its exit, substantially as described.
4th. The simple means of cleansing and renewing the upper only or all the strata
of filtering medium with only drawing one or two cork or other plugs, substantially
as described.
5th. The impossibility of the arrangement being tampered with wittingly or
unwittingly without damage, substantially as described.
