Improvements in Filters.
FREDERICK ROGERS LIPSCOMBE 45 Queen Victoria Street. London E.C.
Water Filter Manufacturer. I do hereby declare the nature of this invention to
be as follows :—
A filter constructed according to my invention has for general object the
compelling of the water or other liquid passed through it to do so in a circulatory
manner, so that the water or other liquid to be treated may be kept as long a
time as possible in contact with the filtering media, or with any mechanical
arrangement, or with both, placed in the filter to act upon it.
The above mentioned conditions are effected by my placing obstructions in the
form of plates, preferably, made of earthenware or other suitable material at
intervals in the filtering vessel, so that the flow of water or other liquid is round
the edge of one plate, which is made of less diameter than the filtering vessel,
and then through a hole or holes in centre of the next plate which is made to
touch the sides of the filtering vessel all round, and so on alternately to the hole
in side or other part of filtering vessel to which is attached the pipe delivering
the purified liquid to a container.
For the mechanical separation of greasy or other matter in suspension from
water or other liquid the filtering vessel may be provided with a false bottom
into which are fitted a number of perforated tubes round which may be wound
cord or other material, into which material may be plaited, bristles, wire, or
woollen fabric, which will attract or retain any greasy or other matter held in
suspension in the water or other liquid passed through or among them, these
tubes with their appurtenances are made to pass through holes in each of the
obstructing plates mentioned above, and these plates themselves may be furnished
with an arrangement of bristles, wire, or other material in order further to
extend the retaining or attractive surface for the greasy or other matter in
suspension and desired to be abstracted from the liquid under treatment.
The obstructing plates may be fixed upon a central movable rod which by
alternate pulling and pressing can be made to pass up and down the perforated
tubes, and so remove from the bristles surrounding them, any greasy or other
matter adhering, or force such matter through the perforations in tubes when it
will gravitate into the false bottom of filtering vessel thence to be removed by a
suitable aperture.
My invention is applicable to filters under pressure or by gravitation.

FREDERICK ROGERS LIPSCOMBE. 45 Queen Victoria Street London E.C.
Water Filter Manufacturer. I 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:-
manner,
A filter constructed according to my invention has for general object the
compelling of the water or other liquid passed through it to do so in a circulatory
and also the filter is so constructed as to divide the water or other liquid
in its passage through the filter, that such water or other liquid may more easily be
kept in contact with each and every part of the filtering media, or with any
mechanical arrangement, or with both, placed within the filtering vessel in order to
purify it, and also the filter is so constructed as to present a very large filtering
area to the water or other liquid passed through it, and also the filter is so
constructed that it may be easily cleansed.
The above mentioned conditions are effected by my placing obstructions to the
passage of the water or other liquid to be treated in the form of movable or fixed
plates B. B. B. in the drawings Fig. 1, or a combination of both, preferably made
of earthenware or other suitable material at intervals within the filtering vessel,
and filling up the spaces between with suitable filtering media A in the drawings
Fig. 1, so that the flow of water or other liquid admitted at one end of the filtering
vessel, and passing through it to the other end, is round the edge of one obstructing
plate, which is made of less diameter than the inside of the filtering vessel, and
then through a hole of holes pierced in the centre of the next obstructing plate,
which is made to touch the sides of the filtering vessel all round, and so on
alternately round and through all the obstructing plates to a hole in the side or in
other convenient part of the filtering vessel, to which may be fitted a pipe delivering
the purified liquid to a container.
The filtering vessel may be further provided when required with a perforated
false bottom B in the drawings Fig. 2, over each hole of which are fitted perforated
tubes C. C. C. Fig. 2, around such tubes may be wound cord or other suitable
material into which has been plaited bristles, wire, woollen fabric, sponge &c.
1) Fig. 2.
The cores of the perforated tubes E. E. E Fig. 2 may be provided with such
filtering media as is best calculated to further purify the liquid which has passed
through the outer coating of the tubes. These tubes with their appurtenances are
made to pass through holes pierced in the obstructing plates, made as explained
above F F F Fig. 2, or all the obstructing plates used in this combination may be
made to touch the sides of filtering vessel all round.
The inlet pipe H Fig. 2 admitting the impure water or other liquid to be treated
to filtering vessel is preferably fitted through the centre of one end of the filtering
vessel, and passing through the false bottom almost to the other end of the filtering
vessel is stopped by a plug. This inlet pipe is perforated at intervals from the
false bottom to its other end stopped by plug, and admits the impure liquid to be
treated between each of the obstructing plates simultaneously. The outlet I
Fig. 2 for the purified liquid is preferably made in the side of the false bottom of
the filtering vessel, and may communicate with an outer vessel surrounding the
first and containing filtering media or mechanical arrangement placed there iu
order to obtain a still further purification of the liquid passed through it, the
purified liquid may be drawn off preferably from an outlet pierced in the top part
of this outer vessel.
By another combination and arrangement of the same invention I take a filtering
vessel provided with a perforated false bottom B Fig. 3, over each hole of which

page_text: are fitted hollow tubes without perforations in their sides C C C Fig. 3, extending
from the false bottom to nearly the other end of the filtering vessel, the core of
each tube D D Fig. 3 may be provided with a movable rod upon which are fixed
suitable materials calculated to arrest matter in suspension in the liquid passed
through them, the space between the sides of the filtering vessel and the tubes
described may also be occupied with suitable filtering media G Fig. 3, separated
when required by a convenient number of obstructing plates E E E Fig. 3 pierced
with holes to pass over the tubes into their places.
The obstructing plates at either or both ends of the filtering vessel may be
acted upon by a screw or other suitable presser, which upon application will press
from any elastic filtering media such as sponge any impurities in suspension in the
liquid passed through which may have accumulated there. In the sides of the
filtering vessel preferably immediately above the false bottom preparations are
made to enable the liquid under treatment to escape into an outer vessel,
surrounding the-first and fixed to it, which outer vessel may also be provided with
an arrangement of hollow tubes and cores as explained above, or be filled with
suitable filtering media or mechanical arrangement in order further to purify the
liquid passed through. The aperture I Fig. 3 for the drawing off of the purified
water or other liquid is preferably made in the side of top part of outer vessel.
The inlet pipe H. Fig. 3 admitting water or other liquid to be purified to the
filtering vessel is preferably fitted into one end of it in the true bottom.
Each and all of the arrangements of a filter constructed according to my
invention can be worked by gravitation, by suction, or by pressure, by uncovering
one end of the filtering vessel, or by closing both ends.
A reference to the drawings will explain.
