PROVISIONAL SPECIFICATION.
Improved Construction or Arrangement of Apparatus for Filtering
Beers and other Liquids.
I, DENNIS WICKHAM, of Star. Brewery, Ware, Hertfordshire, Brewer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for filtering beers and other liquids.
For the purpose of my invention, I construct a cylindrical shape of vessel with
a dished bottom, the upper edge being recessed for the reception of a packing
ring on to which the cover with an internal flange can be secured by fly or other
nuts and bolts as fasteners, which bolts pass through holes of exterior flanges
for the purpose. The interior of the cylinder has a depending screen or shield
from near the top to near the bottom, and has one or more bottom lips on which
cross bars can rest for supporting perforated trays or meshed wirework par-
titions, on which the filtering media can be placed, there being triangular shaped
rings near the edges which retain the filtering media in compact condition and
prevents unnecessary side swaging yet ensuring a perfect closing between the
edges of the trays or partitions and of the cylinder.
These triangular shaped rings may be loosely fitted or attached as desired.
The upper part of the cylinder has a somewhat coarse meshed or perforated
partition to collect the larger particles of material fed to the apparatus, say,
under pressure from a supply pipe of the lid or cover which is also provided with
a pressure gauge and a draw off tap for removal of air at starting."
A liquid draw off tap is fitted to the side of the cylinder near the top, the draw
off being from the space between the cylinder and the depending screen or shield
and said draw off tap may be in connection with a socket to which an extra tap
can be affixed for testing purposes.
I prefer to set the cylinder on a stand of convenient height and provide the
dished bottom with a sludge tap, or for emptying the cylinder previous to the
cover being removed for the renewal of the filtering media.
The apparatus is preferably of a portable character and is specially applicable
for aërated beers ready for being bottled off direct therefrom.

༽、
This invention relates to. apparatus for filtering beers and other liquids.
For the purpose of my invention and as I show on the annexed drawings,
Figure 1 part sectional elevation, and Figure 2 a plan with the cover removed,
I construct a cylindrical shape of vessel A with a dished bottom B, the upper
edge being arranged for the reception of a packing ring C on an internal flange E
on to which a cover D can be secured by fly or other nuts F and bolts as
fasteners, which bolts pass through holes of exterior flanges G for the purpose.
The interior of the cylinder has a depending screen or shield H from near the
top to near the bottom, and has one or more lips on which cross bars I can rest
for supporting perforated trays or meshed wirework partitions J, on which the
filtering media can be placed, there being triangular shaped rings K near the
edges which while serving to close the joints between the trays J and the
screen H by compression or wedging of the filtering material between themselves
and the side of the screen on pressure being applied by means of the bolt which
holds the plates together, thus preventing free passage of the liquid to be filtered,
also retain the filtering media in compact condition and prevent unnecessary side
swaging yet ensuring a perfect closing between the edges of the trays or par-
titions J and of the cylinder screen H. These triangular shaped rings K may
be loosely fitted or attached as desired, or may be substituted, by deep angled
rings such as I show at L.
The upper part of the cylinder has a somewhat coarse meshed or perforated
- partition M to collect the larger particles of material fed to the apparatus, say,
under pressure from a supply pipe to the nozzle N of the lid or cover D which
is also provided with a pressure gauge P and a draw off tap Q for removal of air
at starting. A liquid draw off tap R is fitted to the side of the cylinder near
the top, the draw off being from the space S between the cylinder A and the
depending screen or shield H, and said draw off tap may be in connection with
a socket to which an extra tap T can be affixed for testing purposes.
I prefer to set the cylinder on a stand U of convenient height, and provide
the dished bottom B with a sludge tap V, or for emptying the cylinder A previous
to the cover D being removed for the renewal of the filtering media.
The apparatus is preferably of a portable character and is specially applicable
for aërated beers ready for being bottled off direct therefrom.
Ar
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In an apparatus for filtering beers and other liquids, the combination of
outer cylinder A, inner suspended screen H, space S, of a filter vessel in which
trays provided with wedge rings K or L serve to make liquid-tight the edges
of the trays and supports for edges of filtering medium, as described and sub-
stantially as shown.
