PROVISIONAL SPECIFICATION.
An Improved Filter for Wines and other Liquids.
I, THEOBALD FRIEDRICH SEITZ, of Kreusnach, in the Empire of Germany,
Merchant, do hereby declare the nature of this invention to be as follows:-
The improvement consists in the peculiar formation of the filtering cells:
receiving the liquid required to be filtered and of the cells receiving the filtered
liquid, these cells consisting of walls w arranged at an inclination relatively to one
another, as well as in the general construction of the filter which can be con-
veniently manipulated and readily cleaned while being at the same time highly
efficient.
The filtering material consists of particularly suitable substances such as
asbestos for instance and the like which is torn into fine shreds or fibres; this
filtering material is allowed to float in the liquid to be filtered and is deposited
along the inner walls of the cells.
Figure 1 of the accompanying drawings is a longitudinal section of the filter
Figures 2 and 3 being sections on lines a, and c, d of Figure 1 respectively. The
filter shell or casing g is furnished with a bolted on bottom and top or lid and is
rendered water tight by any suitable means. In this casing inclined walls of fine
tinned wire gauze are arranged in such a manner as to form cells and between
them. The walls of the cell =¹ do not extend to the bottom of the casing so that
communication is formed between the several cells 2. From each one of the
cells an outflow cock h extends outside through the wall of the casing or shell.
The liquid requiring to be filtered is-conveyed through the inlet piper to the
pipe extending under the lid of the casing and the necessary quantity of filtering

openings o in the pipe and runs subsequently over the sieve or plates b arranged
between the pipe and the cells and serving to distribute the liquid. This sieve
may either be horizontal or have the shape of a roof and regulates the floating
of the filtering material. The liquid rushing out of the cells ¹ towards the
cells passes through the floating filtering mass and is cleared. The uniform
action of the filtering mass is ensured by allowing the filtered liquid to run off at
the highest point, whereby the filtering substance is surrounded by and enclosed in
the liquid. The filtered liquid is let off through the cock k which is connected by
means of the outflow pipes and the tubular necks s' with the cells. A second
outlet contrivance k' is provided at the bottom of the casing for the purpose of
allowing the withdrawal of the last drops of filtered liquor after the layers of the
filtering material have been formed.
The filter shewn in Figures 4 and 5 forms a modification of the above described
construction; which is more particularly adapted for filtering smaller quantities of
liquids and for pharmaceutical purposes, in chemical works where volatile oils and
the like are manufactured. It consists of the conical vessel g open at the top as
well as at the bottom the upper opening being covered by a lid d to which is
connected a feeder e at the top; below is arranged a funnel shaped wire gauze
which is soldered, while a perforated plate or sieve b provided with a handle
placed loosely on the rim of the lid, the wire gauze funnel is surrounded by a
funnel shaped vessel of sheet metal but somewhat wider. If the liquid required
to be filtered is poured with the filtering material into e, it will be first conveyed
through the sieve plate bacting as a distributor into the wire gauze funnel in such
is

surfaces. The filtered liquid passing through the wire gauze funnel
passes over
the edge of the sheet metal cone gl and thence through the lower openings of the
casing into a vessel placed below the same. When a sufficient mass of filtering
material has floated, the cock y is opened allowing a direct outflow of the filtered
liquid, without the latter having to rise first in the conical vessel g. The filter
shewn in Figures 1 to 3 can be as readily cleaned as the filter shewn in Figures 4
to 5, as they both can be taken to pieces so that all the parts are easily accessible.
To stiffen or strengthen the wire gauze walls w the latter may be surrounded by
wire gauze having wide meshes. Instead of using wire gauze in the formation of
the cells any other suitable porous material may be used such as for instance:
silica, fabrics and the like. The inclined position of the cell walls allow the
floating filtering mass to adhere better thereto than to vertical walls.

I, THEOBALD FRIEDRICH SEITZ of Kreusnach in the Empire of Germany,
Merchant, 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 :-
The improvement consists in the peculiar formation of the filtering cells receiving
the liquid required to be filtered and of the cells receiving "the filtered liquid;
these cells consisting of walls w arranged at an inclination relatively to one
another, as well as in the general construction of the filter which can be con-
veniently manipulated and readily cleaned while being at the same time highly
efficient.
The filtering material consists of particularly suitable substances such as asbestos
for instance and the like which is torn into fine shreds or fibres; this fiitering
material is allowed to float in the liquid to be filtered and is deposited along the
inner walls of the cells.
Referring to the drawings filed with my Provisional Specification in which
Figure 1 is a longitudinal section of the filter, Figures 2 and 3 being sections on
lines a b and c d of Figure 1 respectively, the filter shell or casing 9 is furnished
with a bolted on bottom and top or lid and is rendered water tight by any suitable
means. In this casing inclined walls of fine tinned wire gauze are arranged in
such a manner as to form cells 21 and 2 between them. The walls of the cell ='
do not extend to the bottom of the casing so that communication is formed
between the several cells 2. From each one of the cells z¹ an outflow cock h
extends outside through the wall of the casing or shell. The liquid requiring to
be filtered is conveyed through the inlet pipe to the pipe extending under
the lid of the casing and the necessary quantity of filtering material is mixed
therewith through the hopper t. The mixture passes through openings o in the
pipe and runs subsequently over the sieve or plates 6 arranged between the pipe
and the cells and serving to distribute the liquid. This sieve may either be
horizontal or have the shape of a roof and regulates the floating of the filtering
material. The liquid rushing out of the cells z towards the cells passes through
the floating filtering mass and is cleared. The uniform action of the filtering mass
is ensured by allowing the filtered liquid to run off at the highest point, whereby
the filtering substance is surrounded by and enclosed, in the liquid. The filtered
liquid is let off through the cock k which is connected by means of the outflow

page_text: pipes and the tubular necks s¹ with the cells. A second outlet contrivance k¹ is
provided at the bottom of the casing for the purpose of allowing the withdrawal
of the last drops of filtered liquor after the layers of the filtering material have
been formed.
The filter shewn in Figures 4 and 5 forms a modification of the above described
construction which is more particularly adapted for filtering smaller quantities of
liquids and for pharmaceutical purposes, in chemical works where volatile oils and
the like are manufactured. It consists of the conical vessel 9 open at the top as
well as at the bottom the upper opening being covered by a lid d to which is
connected a feeder e at the top. Below is arranged a funnel shaped piece of wire
gauze which is soldered to the lid d while a perforated plate or sieve 6 provided
with a handle is placed loosely on the rim of the lid, the wire gauze funnel
being surrounded by a funnel shaped vessel of sheet metal but somewhat wider.
If the liquid required to be filtered is poured with the filtering material into e it
will be first conveyed through the sieve plate b acting as a distributor into the
wire gauze funnel in such a manner as to cause a uniform deposit of the filtering
material along the filtering surfaces. The filtered liquid passing through the wire
gauze funnel passes over the edge of the sheet metal cone g' and thence through

the lower openings of the casing into a vessel placed below the same.
sufficient mass of filtering material has floated, the cock y is opened allowing a
direct outflow of the filtered liquid, without the latter having to rise first in the
conical vessel g. The filter shewn in Figures 1 to 3 can be as readily cleaned as
the filter shewn in Figures 4 to 5, as they both can be taken to pieces so that all
the parts are easily accessible. To stiffen or strengthen the wire gauze walls w the
latter may be surrounded by wire gauze having wide meshes. Instead of using
wire gauze in the formation of the cells any other suitable porous material may
be used such as for instance, silica, fabrics and the like. The inclined position of
the cell walls allows the floating filtering mass to adhere better thereto than to
vertical walls.
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 for wine and other similar liquids characterized by a group of cells 2¹
formed of walls wo of wire gauze arranged at an inclination relatively to each other
whereto the liquid requiring to be filtered and which is mixed with the filtering
material is conveyed through a pipe r¹ extending above these cells and after having
passed through a sieve plate acting as a distributor this liquid forcing its way
through the floating filtering material, passes over towards the second group of
cells whence the now filtered liquid may be drawn off through the upper
cock k or a lower cock such as k¹, substantially as described with reference to
Figures 1, 2 and 3 of the annexed drawings.
2. The modification of the filter described in Claim 1 and its adaptation as a
suitable apparatus for smaller quantities of liquid consisting of a casing g
surmounted by a lid connecting the feeder e with the funnel to which is surrounded
by the conical receptacle g¹ and is formed of wire gauze or of porous material, a
perforated plate acting as a distributor, being arranged between them,
substantially as described with reference to Figures 4 and 5 of the annexed
drawings.
