Improvements in and relating to Filtering Apparatus.
I, HEINRICH JÜRGEN ERNST JENSEN, of 54, Feldstrasse, in the City of
Hamburg, Germany, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to apparatus for filtering liquids such as wine, beer and the
like by means of a layer of asbestos or similar fibre.
The improved apparatus mainly consists of an upper inlet or distributing chamber
containing a supply funnel and carrying at its lower and somewhat contracted end
the, preferably cylindrical, filtering surface, and of a lower chamber adapted to
collect the filtered liquid. The outlet of the supply funnel within the upper or
distributing chamber is, at its lower end, closed by a solid plate which projects all
around the lower tube of the funnel to a certain extent, so that the liquid to be
purified and entering the said funnel, is caused to flow off into the distributing
chamber in a radial direction through a number of holes in the wall of the down-
wardly extending narrow outlet tube of the funnel. By the said bottom-plate of
the outlet tube, a deflection of the liquid is effected towards the surrounding wall
of the said inlet chamber in order that the current of the liquid supplied through
the said funnel shall be uniformly conducted into the actual filtering chamber.
The latter has a solid bottom and a perforated peripheral surface or wire gauze
sieve lined with asbestos or similar fibre. In consequence of this arrangement, the
liquid to be purified, flows uniformly from the supply funnel through the filtering
layers in such a manner that no whirlings are produced which would cause an
irregular settling of the asbestos or similar filtering fibres upon the wire gauze
surface of the filter.
The filtered liquid may be drawn off from the collecting vessel through a valve
or cock and a float-valve or cock may be provided at the inlet chamber to regulate
the supply of unpurified liquid according as the filtered liquid is drawn off from the
collecting vessel.

Improvements in and relating to Filtering Apparatus.
1, HEINRICH JÜRGEN ERNST JENSEN, of 54, Feldstrasse, in the City of
Hamburg, Germany, Manufacturer, 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 improvements in and relating to filtering apparatus for
filtering liquids such as wine, beer and the like, by means of a layer of asbestos or
similar fibre; aud my invention consists in certain novel features of construction
and combinations of parts, as will be hereinafter fully described, and pointed out in
the claims.

page_text: In order that my invention may be more fully understood I have illustrated the
same in the accompanying drawing in which
Figure 1 is a central vertical section of my improved filtering apparatus;
Figure 2 is a top view of the same; the supply valve of the apparatus shown as
opened in both the figures.
Figure 3 is a similar section as Figure 1 showing the supply valve in its closed
position.
Figure 4 illustrates a modification of the upper part of Figs. 1 and 3.
Similar letters refer to similar parts throughout the several views.
In some
The improved apparatus consists of an upper inlet or distributing chamber a
containing a supply funnel ↳ and carrying at its lower and somewhat contracted
end a', the preferably cylindrical filtering surface e, and of a lower chamber d
adapted to collect the filtered liquid. The outlet of the supply funnel within
the upper or distributing chamber a, is at its lower end and is closed by a solid
plate which projects all around the lower tube of the funnel to a certain extent,
so that the liquid to be purified and entering the said funnel b, is caused to flow off
into the distributing chamber a in radial direction through a number of holes & in
the wall of the downwardly extending narrow outlet tube of the funnel.
cases, the perforated tube may be dispensed with and the lower mouth of the
funnel set at a small distance from the bottom plate, so that the liquid flowing
over the edge of the bottom plate will form a bell shape (Fig. 4). By
the said bottom-plate of the outlet tube, a deflection of the liquid is effected
towards the surrounding wall of the said inlet chamber a in order that the
current of the liquid supplied through the said funnel may be uniformly conducted
into the actual filtering chamber c. The latter has a solid bottom c² and a
perforated peripheral surface or wire gauze sieve c¹ lined with asbestos or
similar fibre. In consequence of this arrangement, the liquid to be purified flows
uniformly from the supply funnel through the filtering layers on c in such a
manner that no whirlings are produced which would cause an irregular settling
of the asbestos or similar filtering fibres (carried along with the entering liquid
when the filtering apparatus is started) upon the wire gauze surface c¹ of the
filter c.
The filtered liquid may be drawn off from the collecting vessel d through a valve
or cock e and a suitable ball-valve or cock may be provided at the inlet chamber in
order to regulate the supply of unpurified liquid according as the filtered liquid is
drawn off from the collecting vessel d.
The ball cock shown in the figures forms a somewhat modified faucet in which
the cock turns around the plug-shaped end of the supply pipe i, and is made to
open or close an aperture of the plug i so that the liquid may accordingly pass
through this aperture into the spout and into the pipe g extending from the
latter. The faucet is opened or closed by means of a ball fattached to the pipe g
and floating on the surface of the liquid in the funnel 6 so as to allow the cock to
remain open until the liquid has attained a certain level, but when the liquid rises
beyond this level, the said ball of closes the cock h, as indicated in Figure 3 to
stop the supply till the liquid in the funnel & sinks again below the aforesaid level.
The outlet arms or branches gl of the pipe g extend or project downward to such
an extent that they always dip into the liquid contained in the funnel thus causing
the supply of the unpurified liquid to the funnel to take place beneath the surface
of the liquid in the funnel and without mixing with the air.
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 filtering apparatus which consists of a distributing chamber a somewhat
contracted at its lower end a', of a supply funnel 6 provided with a distributing
plate, of a filtering chamber e formed by a perforated surface or wire gauze
sieve c¹ to be lined with asbestos or similar filtering fibres and attached to the

page_text: contracted part a' of the chamber a, and of a collecting chamber d with an outlet
device e, all arranged substantially as set forth and for the purpose specified.
2. In a filtering apparatus, the combination of a distributing chamber a a¹, a
filtering chamber ccc, a collecting chamber d and a supply funnel 6 b', with a
ball valve or cock having a stationary slotted hollow plug and a movable
casing to which is attached a pipe 9 carrying the ball f, substantially as and
for the purpose specified.

3. In a filtering apparatus the combination of a distributing chamber a a¹, a
filtering chamber cc, a collecting chamber d and a funnel 6 b with a ball cock
the pipe g of which is provided with one or more outlet arms or branch pipes g'
adapted to discharge the liquid below the surface of the liquid within the supply
funnel, substantially as and for the purpose set forth.
