Year: 1875

page_text: LETTERS PATENT to Charles Lambert, of Sunk Island, Hull, in the
County of York, for the Invention of "IMPROVEMENTS IN FILTERS OF
APPARATUS INTENDED CHIEFLY TO CLEAR RAIN WATER DURING ITS FLOW
FROM ROOFS TO RESERVOIRS."
Sealed the 27th July 1875, and dated the 30th January 1875.
PROVISIONAL SPECIFICATION left by the said Charles Lambert at
the Office of the Commissioners of Patents, with his Petition, on
the 30th January 1875.
I, CHARLES LAMBERT, of Sunk Island, Ilull, in the County of York,
IMPROVEMENTS
do hereby declare the nature of the said Invention for
IN FILTERS OR APPARATUS INTENDED CHIEFLY TO CLEAR RAIN WATER DURing its
FLOW FROM ROOFS TO RESERVOIRS," to be as follows:-
This Invention relates to improvements in filters or apparatus intended
chiefly to clear rain water during its flow from roofs to reservoirs, the
object being the construction of apparatus that can be attached, say, to
a wall of a building, and be put in connection with a down rain water

page_text: pipe, so that the water can before it 'runs to a tub, cistern, or other
reservoir be rendered comparatively clear or into a state fit for domestic
and other purposes for which such may be suitable.
The apparatus consists of an outer casing with lugs by which it can
be attached to a wall. This outer casing has an inner vessel, into which
the descending water from a roof is permitted to flow by an attachment
of the down pipe with it in any suitable manner.
The bottom of the inner vessel is closed, except to a hole in which a
cork or plug can be fitted to allow of the inner vessel being cleared of
the sediment which settles at that part. The upper part of the inner
vessel has one or more openings, into which boxes supplied with charcoal
or other filtering medium can be placed, the box or boxes being retained,
suspended from the rim by thumbscrews or other appliances by which
the boxes can be removed from time to time when the boxes require
refilling with the filtering medium or for other purposes. The upper-
part of each box has preferably a kind of bail or handle by which it can
be lifted, and on which the screw presses to hold the box rim down upon
its seating. The filtering medium is held between two or more perforated
plates, and the water which flows through them from the chamber of
the inner vessel has to flow over the top into passages, say at cach side
between the casing and the vessel, down which it passes to an outlet
common to both, and from there to a tub, cistern, or other reservoir.
I provide a separate outlet above the level of the outer casing, this
being in connection with an overflow pipe leading to a drain or to some
other channel or to a cistern, so that should the filtering portion become
blocked from frost or other cause a passage remains open for the
discharge.
The face of my apparatus may have a plate of glass fitted in the front
to enable a person to ascertain the depth of the sediment within the
vessel, which glass may be protected by a shield.
The thumbscrews are arranged in sliding cover plates which enclose the
inner vessel and the filtering boxes to protect them from the weather.
The apparatus can be fitted for supplying portable or other engines
or machines in or to which rain, ditch, or other-water can be made
available.

filed by the said Charles Lambert in the Great Seal Patent Office
on the 30th July 1875. .
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
LAMBERT, of Sunk Island, Hull, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of January, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Charles Lambert, Her special
licence that I,. the said Charles Lambert, my executors, adminis-
trators, and assigns, or such others as I, the said Charles Lambert,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man,' an Invention for "IMPROVEMENTS
IN FILTERS OR APPARATUS INTENDED CHIEFLY TO CLEAR RAIN WATER DURING ITS
FLOW FROM ROOFS TO RESERVOIRS," upon the condition (amongst others) that
I, the said Charles Lambert, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
.
NOW KNOW YE, that I, the said Charles Lambert, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say:-
This Invention relates to improvements in filters or apparatus intended
chiefly to clear rain water during its flow from roofs to reservoirs, its
object being the construction of an apparatus that can be attached, say,
to a wall of a building, and be put in connection with a down rain water
pipe, so that the water can before it runs to a tub, cistern, or other

page_text: .
reservoir be rendered comparatively clear or into a state fit for domestic
and other purposes for which such may be suitable.
The apparatus, as shown in Figures 1 and 2 of the Drawings annexed,
consists of an outer casing. A with lugs B, B, by which it can be attached
to a wall. This outer casing has an inner vessel C, into which the
descending water from a roof is permitted to flow by an attachment D of
the down pipe E with it.
i
The bottom of the inner vessel C is closed, except to a hole G, in.
which a cork or plug can be fitted to allow of the inner vessel being
cleared of the sediment which settles at that. part. The upper part II of
the inner vessel C has openings, into which boxes I, I, supplied with
charcoal or other filtering medium can be placed, the boxes I, I, being
retained suspended from the rims by thumbscrews J, J, or other appli-
ances. The boxes can be removed from time to time when they require
refilling with the filtering medium or for other purposes. The upper
part of each box has preferably a kind of bail or handle K, K, by which
it can be lifted, and on which the screws J, J, press to hold the box rim
down upon the seating, a layer or ring of india-rubber or other equiva
lent material being placed between as a washer for tightness. The
filtering medium is held between two or more perforated plates L, M,
and the water which flows through them from the chamber of the inner
vessel C has to flow over the top into passages P, P, at each side
between the casing A and the vessel C, down which it passes to an
outlet Q common to both, and from there to a tub, cistern, or other
reservoir.
"
I provide a separate outlet Rabove the level of the outer casing A,
this being in connection with an overflow pipe leading to a drain or to
some other channel or to a cistern, so that should the filtering portion
become blocked from frost or other cause a passage remains open for the
discharge.
'
I propose that the face of my apparatus should have a plate of glass S
fitted in the front to enable a person to ascertain the depth of the
sediment within the chamber N, which glass may be protected by a
shield:
t
The thumbscrews J, J, are arranged in sliding cover plates T; T; which
enclose the inner vessel C and the filtering boxes I, I, to protect them
from the weather

page_text: The apparatus can be fitted for supplying portable or other engines
or machines in or to which rain, ditch, or other water can be made
available.
In the view I have shown the filter apparatus of rectangular shape,
with a curved bottom, but I do not limit myself thereto, neither do I
limit myself to placing it in any position, nor to use the filter for any
special purpose. In the case of house filters they may be made to fit
the service pipe leading to kitchen sink or otherwise.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,—
The construction and arrangement of vessels and filter boxes for
receiving and for filtering rain and other water, as hercin-before described
and as shown in the accompanying Drawings, or any mere modification
thereof.
Secondly. I claim constructing and arranging apparatus for the
separation of stones and foreign bodies from rain water, and for. the
upward filtration of rain water on its way from eaves, gutters, to
receptacles, as and for the purposes set forth.
In witness whereof, I, the said Charles Lambert, have hereunto
set my hand and seal, this Twenty-seventh day of July, One
thousand eight hundred and seventy-five.
