I, WILLIAM HUCKS of 12 Oval Road Upper James Street Camden Town N.W.
in the County of Middlesex do hereby declare the nature of my invention for
IMPROVEMENT IN THE SEPARATION OR FILTERATION OF SOLID AND LIQUID MATTER
to be as follows:-
--
This invention is designed for the filteration of all Liquids, but more particularly.
for the separation of meal from worts, pulp from paper washings, and sludge from
sewage matter, It consists of a travelling or revolving diaphragm, arranged in
such a manner as to receive the liquid on a portion of its surface, The diaphragm
or seive shall be formed into an endless band travelling or revolving in such a
manner that the solid matter collected on its surface shall be brought out of the
liquid (passing through it) and the aforesaid solid matter delivered into a separate
vessel, the diaphragm or seive after having thrown off its surface the solid matter:
into a separate vessel, shall be between this point and its again re-entering the
liquid (that is being filtered) subjected to a process of clensing by means of
revolving brushes, jets of water or any other. suitable means, so as to offer a clean
surface to re-enter the liquid that is being filtered.
I wish it to be understood that, owing to the diaphragm or filtering medium
being capable of continuous movement, the following several processes, can be:
carried on simultaneously and continuously viz Filtering the liquid Desiccating
compressing or othewise treating the solid particles or matter separated by the
filtering medium Clensing filtering surface and preparing same. by the introduction
of any suitable medium such as sand charcoal or othewise on the surface of,
travelling seive so as to form a suitable diaphragm before re-entring the liquid.
which is being filtered.
Further I do not bind myself to a revolving motion only but any movement that
will enable me to remove the solid matter collected on filter and clensing of same
before returning into liquid that is being filtered.
The novelty I claim is that at one and the same time the filter bed can be moved;
without stopping the process of filteration Solid matter collected on filter can be
deposited into a separate vessel. Filter bed can be clensed, thus rendering the
process of separating solid matter from liquid (and the removal of the aforesaid,
solid matter) by filteration a continuous in place of an intermittent process.

I, WILLIAM HUCKS of 12 Oval Road Upper James Street, Camden Town in the
County of Middlesex Engineer 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:-
"
My invention relates to the filtration of all liquids and is designed to provide
a filtering medium or diaphragm arranged in such a manner, as to be capable
of separating and removing any solid matter present in a liquid, the separation
and removal of the solid matter, and the clensing of the filtering medium or
diaphragm, to proceed at the same time the liquid is being filtered, the solid matter
so separated from the liquid is capable of being compressed, desiccated or otherwise
treated during its removal from the liquid to any given point.
My improvements are applicable to the filtration of all liquids, but more parti-
cularly to the separation of Meal or Grist from Worts, Pulp from paper washing,
and sludge from sewage matter.
My invention consists of a travelling or revolving diaphragm or filtering medium
arranged in such a manner as to receive the liquid on a portion of its surface.
The diaphragm or seive shall be formed into an endless band revolving in such a
manner as to be capable of collecting on its surface the solid matter contained in
the liquid which is passing through it.
The solid matter as it is elevated from the liquid may be compressed by the
rollers or any other means to more effectually remove any moisture present if
necessary, or the solid matter so separated may be carried to any given height
either for the object of draining the moisture from it, or for the purpose of elevating.
it to any given point, when the solid matter is removed from the surface of the
diaphragm or filtering medium, this diaphragm, seive, or filtering medium, may be
cleaned by scrapers made of metal, india-rubber, or any suitable material, also
revolving brushes, jets of water or any other means found necessary for cleaning
the diaphragm or filtering medium before again entering the liquid which is being
filtered. Also on again entering the liquid it may be found desirable to introduce
on the surface of the diaphragm or seive some material such as sand, charcoal,
coke-dust, dry earth or any substance which may form a suitable filtering medium
for separating the solid matter present in the liquid to be filtered.
In the accompanying drawings sheets 1. 2. & 3, I have shewn sectional elevations
of side and end of travelling diaphragm arranged to carry out the several conditions
of filtration as described in my invention.
Sheet 1. Figs. 1 & 2, show the arrangement of the diaphragm or seive e, e, e, e,
arranged as an endless band passing over and under the rollers or wheels a, a, a, a,
moving in the direction as indicated by the arrows and thus conforming. the
diaphragm or band e, e, e, e, to the shape of the trough m, m, m, thus making the
receptacle to hold the unfiltered liquid, and in its passage through the diaphragm
or band the solid matter present is collected on one side of its surface.

page_text: When the band e, e, e, e, is set in motion the solid particles are brought out of the
liquid which is being filtered and thrown off at the point g, as the diaphragm or
seive continues to move from point.g, it again enters the unfiltered liquid at the.
point 7, thus causing a continuous removal of solid matter from the unfiltered liquid
and a constant change of the surface of the diaphragm for the unfiltered liquid to
filter through.
The liquid in the trough shaped vessel m, m, m, pressing on the top side of the
diaphragm or band e, e, e, e, causes it to rest on the fillets d, d, d, d, d, d, d, d, d, d,
Fig. 2.
"
The pressure of the liquid will be found enough to make the band or seive
sufficiently water tight to prevent the liquid passing otherwise than through it.
Sheet 2. Figs. 3, & 4, represent the diaphragm or band passing over one roller at
the point o, and entering the bottom of the trough between two rollers coated with
some suitable elastic material at the point p.
The sides and bottom of trough are packed at the points 8, 8, where the rollers
revolve in order to render the trough f.f, sufficiently water tight. I have also
shewn two rollers c, & d, suitable for pressing the moisture from the solid matter
separated from the movable diaphragm e, e, e, e.
This elevation represents the suitable form of the apparatus for raising the solid
particles separated, to a considerable height.
Sheet 3. Figs. 5, & 6, represent the diaphragm over and under a set of four rollers
or wheels a, a, a, a, thus adapting the form of the diaphragm or band e, e, e, e, to
the shape of the trough h, containing the unfiltered liquid entering by the inlet 1,
passing through the diaphragm to bottom of trough running out by the outlet m,
the sliding boards g, g, answer several purposes.
First to prevent the unfiltered liquid coming in contact with the portion of the
diaphragm which is passing under the roller a, at the point n. Secondly to scrape
any impurity on the roller referred to and to avoid it being crushed into the
diaphragm at the point n. Thirdly to form a receptacle to hold charcoal, coke-dust
or any suitable material to be distributed on the diaphragm or band so as to assist
the process of filtration, the rollers c, & d are for pressing the moisture from the
separated particles, at this point the separated matter may be further treated by
passing between hot rollers or the diaphragm might pass over a space. heated in a
suitable manner for the purpose of disiccating or otherwise treating the solid
matter separated from the liquid which is being filtered.
The revolving brush k, is for clensing the diaphragm or band before again
entering the trough h, containing the unfiltered liquid. Many processes of washing
and clensing the band or diaphragm may be necessary to clense it before again.
entering the trough containing the unfiltered liquid.
I do not bind myself to propell the rollers by the diaphragm or band as shewn
in these drawings, but if necessary the rollers may actuate each other independently
of the diaphragm either by belts or gear wheels.
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 :-
1. A diaphragm formed into an endless band either jointed or otherwise in such
a manner that it may enter a vessel or trough and in doing so it is capable of
dividing the said vessel or trough into two parts so that any liquid entering the
trough on the top side of the diaphragm must pass through the diaphragm before
it can enter the lower portion of the vessel or trough which the diaphragm has
divided.
2. The arrangement of the diaphragm for the purpose of elevating and removing
the particles separated by filtration from the liquid which is being filtered.
3. The clensing the diaphragm by means of scrapers, brushes, jets of water or
any other means, before again entering the liquid which is being filtered.

page_text: 4. The distribution on the surface of the diaphragm in its progress through the
liquid which is being filtered, of any suitable material which may assist the sepa-.
ration of the solid matter present in the liquid which is being filtered.
5. Generally, a vessel or trough fitted with a moving diaphragm for the removal
of solid matter present in a liquid. The clensing of the medium that is filtering.
the liquid. These several processes to be carried on at the same time without
retarding each other.
