Improvements in and connected with Filters, Water Purifiers, and
Grease Catchers.
WILFRED REEVES of 39 Victoria Street, Westminster, S.W. Engineer, and
THE REEVES PATENT FILTERS COMPANY LIMITED, of 39 Victoria Street,
Westminster S.W. Water Purifiers, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object an improved method of filtering, purifying, &
separating air, grease, metallic oxides, free acids, and other impurities from
liquids, for example; boiler-feed and other water, by passing such liquids through
one or more chambers charged with granular absorbent compounds or materials,
& relates to an apparatus, or filter, constructed so that the absorbent materials
when saturated with impurities can be discharged without opening the filters, and
the chambers re-charged with fresh material as often as required.
The apparatus constructed according to this invention, preferably consists of
three flanged cylinders, bolted, or rivetted together so as to form one cylindrical
chamber, which may be placed vertically, horizontally, or in a diagonal position,
and closed at either end by suitable covers, preferably domed, secured by bolts
or studs.
Inside of this cylinder are placed two perforated grids, or plates, preferably
shaped so that they assume the forms of cones, open at both ends, the larger ends
being flanged, and the smaller ends terminating in the form of a tube. The flanges
of these perforated cones are inserted between the flanges of the cylinders in such
a manner, that the smaller ends of the cones look towards the cylinder covers,
and are secured in place by the bolts or rivets which joint the flanges of the
cylinder, or other suitable means.
Upon the cover of the inlet section of the cylinder is fitted a small door,
covering a hand hole communicating with the internal chamber formed by the
inverted perforated cones, or a removable air-vessel, or a combined air-vessel and
relief valve, may be fitted to take the place of this door.
Upon the cover of the outlet section of the cylinder is fitted a sluice, or
blow-out valve, communicating with the internal chamber forined by the inverted
perforated cones.
A steam-jet cock, or valve, and a drain cock, are fitted in a convenient position
upon the inlet section of the cylinder and a drain cock, or test cock, is preferably,
likewise fitted upon the outlet section of the cylinder.
In the case of a single cylindrical chamber an inlet valve is fitted to the inlet
section of the cylinder, and an outlet valve to the outlet section of the cylinder.
In cases where two cylinders are employed the two inlet sections of the cylinders
are preferably connected to a "twin" inlet valve, and in like manner the two
ower sections are preferably connected to a "twin" outlet valve. These "twin"
valves having, respectively, common inlet openings, and common outlet openings.
It is obvious that two ordinary valves may be used in the place of "twin"
alves.
To these "twin" valves pipe-bends are preferably fitted, looking, respectively,
p, and down, so that the centers of their inlet and outlet openings are in a
common horizontal line, and pipes, conveying the liquid are not deflected.

page_text: The inlet inverted perforated cone is covered on the outside by a glove com-
posed preferably of coarse copper gauze, and the outlet inverted perforated cone
is preferably lined on the inner side with a sufficient number of copper gauze
linings, or other suitable material, so as to prevent the escape of the absorbent
material.
The internal chamber formed by the inverted perforated cones is filled with the
granulated absorbent material (preferably soft wood sawdust).
The two perforated cones are so fitted to the cylinders and covers that the
liquids to be filtered can only pass through their perforations.
In operation, in the case of a single cylinder filter, (assuming the filter to be
charged) the unfiltered liquid enters the filter through the inlet valve on the inlet
section of the cylinder, passes through the coarse copper gauze glove and inlet
inverted perforated cone, permeates the absorbent material, and escapes through
the copper gauze linings and the outlet inverted perforated cone in the outlet
section of the cylinder, whence it passes by the outlet valve to destination.
The operation of cleaning out is as follows:-
In the case of a single cylinder filter, the inlet and outlet valves are closed,
and the blow-out valve on the cover of the outlet section of the cylinder is opened,
at the same time steam is admitted through the steam jet cock, or valve, on the
cover of the inlet section of the cylinder, the absorbent material being thus
instantly expelled by the pressure of the steam. This being accomplished, the
steam jet cock, or valve, and the blow-out valve are closed, and the small door op
the cover of the inlet section is removed, and a fresh charge of absorbent material
is poured in, when the charging door is closed and the inlet and outlet valves
opened, the filter being again placed in circuit.
When two cylinders are employed, one may be shut off for cleaning, as above
described, the other being left in circuit, thus insuring a continuous supply of
filtered liquid.
When it is desirable to use one cylinder only, a by-pass pipe, with suitable valve,
may be employed to keep up the circulation of liquid."

COMPLETE SPECIFICATION.
Improvements in and connected with Filters, Water Purifiers, and
Grease Catchers.
WILFRED REEVES, Engineer, of 39 Victoria Street, Westminster,
London S.W. and THE REEVES PATENT FILTERS COMPANY LIMITED,
Filter Manufacturers, of 39 Victoria Street, Westminster, London S.W. 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 an improved method of filtering, purifying
and separating air, grease, metallic oxides, free acids and other impurities from
boiler feed and other water by passing such waters under pressure or gravity
through one or more chambers charged with granular absorbent compounds or
materials and relates to an apparatus or filter constructed so that the absorbent
materials when saturated with impurities can be discharged without opening the
filters and by means of the employment of duplicate chambers the said chambers
can be recharged with fresh material as often as required without stopping the
process of filtration.

page_text: The apparatus constructed according to this invention preferably consists of
three flanged cylinders (Figs. 1 and 2) bolted or rivetted together so as to form
one or more cylindrical chambers which may be placed vertically, horizontally or
in a diagonal position and closed at either end by suitable covers preferably domed
secured by bolts, studs or rivets.
Inside of these cylinders A (Figs. 1, 2, & 3) are placed two perforated grids or
plates B and B 1 (Figs. 1 and 3) preferably shaped so that they assume the form
of cones open at both ends the larger ends C (Fig. 1) being flanged and the
smaller ends D (Fig. 1) terminating in the form of a tube. The flanges of these
perforated cones B and B 1 are inserted between the flanges E (Figs. 1 and 2) of
the cylinders in such a manner that the smaller ends D (Fig. 1) of the cones B
and B1 (Fig. 1) look towards the cylinder covers F and F 1 (Figs. 1 and 2) and
are secured in place by the bolts or rivets which joint the flanges E (Figs. 1 & 2)
of the cylinders A (Figs. 1 and 2) or other suitable means.
Upon the covers F (Figs. 1 and 2) of the inlet section of the cylinders A
(Figs. 1 and 2) are fitted small doors G (Figs. 1 and 2) covering hand holes
communicating with the internal chambers formed by the inverted perforated
cones B and B 1 (Fig. 1) or removable air vessels or combined air vessels and
relief valves may be fitted to take the place of these doors G (Figs. 1 & 2).
Upon the covers F 1 (Figs. 1 and 2) of the outlet section of the cylinders A are
fitted sluice or blow-out valves H (Figs. 1 and 2) communicating with the internal
chambers formed by the inverted perforated cones B and B 1 (Fig. 1).
Steam jet cocks or valves J (Figs. 1 and 2) and drain cocks are fitted in con-
venient positions upon the inlet sections of the cylinders A (Figs. 1 and 2) and
drain cocks or test cocks L (Figs. 1 and 2) are preferably likewise fitted upon the
outlet sections of the cylinders A (Figs. 1 and 2).
In the case of a single cylindrical chamber an inlet valve is fitted to the inlet
section of the cylinder A and an outlet valve to the outlet section of the
cylinder A.
In cases where two cylinders are employed the two inlet sections of the
cylinders A (Figs. 2 & 3) are preferably connected to a twin inlet valve M
(Figs. 2 and 3) and in like manner the two lower sections are preferably connected
to a twin outlet valve N (Fig. 2). These twin valves M and N having respectively
a common inlet opening and a common outlet opening. It is obvious that two
ordinary valves may be used in the place of twin valves M and N.
To these twin valves M and N pipe bends O (Fig. 2) are preferably fitted
looking respectively up and down so that the centre of their inlet and outlet
openings are in a common horizontal line and pipes conveying the liquid are not
deflected.
The inlet inverted perforated cones B (Fig. 1) are covered on their outsides by
gloves P (Fig. 1) composed preferably of coarse brass gauze and the outlet
inverted perforated cones B1 (Fig. 1) are preferably lined on their inner sides
with a sufficient number of brass gauze linings R (Fig. 1) or other suitable
material so as to prevent the escape of the absorbent material.
I may also make the perforations in the cones sufficiently small to effect this
without the employment of wire gauze.
The internal, chambers formed by the inverted perforated cones B and B 1
(Fig. 1) are filled with the granulated absorbent material preferably soft wood
sawdust.
The two perforated cones B and B 1 (Fig. 1) are so fitted to the cylinders A
(Fig. 1) and covers F and F 1 (Fig. 1) that the liquids to be filtered can only
pass through their perforations.
In operation in the case of a single cylinder filter (assuming the filter to be
charged) the unfiltered liquid enters the filter through the inlet valve on the inlet
section of the cylinder A passes through the coarse brass gauze glove P (Fig. 1)
and inlet inverted perforated cone B (Fig. 1) permeates the absorbent material
and escapes through the brass gauze linings R (Fig. 1) and the outlet inverted

page_text: perforated cone B1 (Fig. 1) in the outlet section of the cylinder A whence it
passes by the outlet valve.
The operation of cleaning out is as follows:-
In the case of a single cylinder filter the inlet and outlet valves are closed and
the blow-out valve H (Figs. 1 and 2) on the cover F 1. of the outlet section of the
cylinder A is opened at the same time steam is admitted through the steam jet
cock or valve J on the cover F of the inlet section of the cylinder A, the absorbent
material being thus instantly expelled by the pressure of the steam.
This being accomplished the steam jet cock or valve J and the blow-out
valve H are closed and the small door on the cover F of the inlet section is
removed and a fresh charge of absorbent material is poured in when the charging
door G is closed and the inlet and outlet valves opened the filter being again placed
in circuit.
Whilst the process of cleaning and filling is going on in one cylinder (Figs. 1, 2
and 3) the other is left in circuit and in this way the process of filtration is
rendered continuous.
When it is desirable to use one cylinder only, a bypass pipe with suitable valve
may be employed to keep up the circulation of the liquid.
It is obvious that the filter may be constructed of one single cylinder instead of
being built up in three or less sections as in Fig. 4. In this case the perforated
grids or cones B 2 and B 3 (Fig. 4) are constructed without flanges on their larger
ends and are not tubular on their smaller ends but are made as plain perforated
cones open at both ends.
Their larger ends rest upon metal rings S (Fig. 4) bolted or rivetted on to the
inner walls of the cylinder A 1. (Fig. 4) and spaced at a suitable distance apart.
Their smaller ends it into the shaped holes in the covers F and F1 (Fig. 4) and
these covers F and F 1 being bolted or rivetted to the top and bottom flanges
of the cylinder A1 (Fig. 4) hold the perforated cones B2 and B3 (Fig. 4) in
position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A filter having the filtering material contained in a chamber having
perforated conical ends with or without wire gauze covering substantially as
described and for the purposes specified.
2. A filter constructed substantially as described with reference to Figs. 1, 2
and 3 of the accompanying drawings.
3. A filter constructed substantially as described with reference to Fig. 4 of the
accompanying drawings.
