PROVISIONAL SPECIFICATION:
Improvements in or connected with Apparatus for Filtering Beers
and other Liquids.
I, HENRI VUYLSTEKE, of 16, Rue du Boulet, Brussels, Belgium, Brewers'
Engineer, do hereby declare the nature of this invention to be as follows:
This invention relates to the construction or arrangement of apparatus by which
beers and liquids generally can be filtered and cleared of flocculent and organic
matters.
For the purpose of this invention, I construct a cylinder slightly narrowed in
at or near the centre, and provide the end plates with slots or openings, into some
of which I arrange perforated plates in pairs, within which I place the filtering
medium of any desired kind, so that the liquid has to pass through the intervening
spaces to the outlet apertures which alternate with the entry apertures, said plates
are kept at their respective distances apart by bridge pieces or stays.
Above and below the perforated plates are chambers formed by the end covers,
into the upper of which the liquid is allowed to flow from a supply tube, this
being a branch from an air vessel provided with a blow off tap or a pressure gauge,
and also with a pipe connection from the upper chamber.
The interior of the cylinder and the surfaces of the plates and all parts with
which the liquid can come into contact are tinned or nickel coated to prevent
metallic action.
The ends of the channels are provided, particularly the upper ends if the
apparatus be vertical, with a perforated plate to retain any solids which may pass
nto the apparatus.
The centrally contracted sides of the cylinder where it comes into contact with
some of the perforated plates compel a detour or second filtering process of the
quid before passing to the outlet passages into the outlet chamber.

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement:-
This invention relates to the construction or arrangement of apparatus by which
beers and liquids generally can be filtered and cleared of flocculent and organic
matters.
For the purpose of this invention, I construct a cylinder slightly narrowed in
at or near the centre, and provide the end plates with slots or openings, into some
of which I arrange perforated plates in pairs, within which I place the filtering
medium of any desired kind, so that the liquid has to pass through to the intervening
spaces to the outlet apertures which alternate with the entry apertures, said plates
aie kept at their respective distances apart by bridge pieces or stays.
Above and below the perforated plates are chambers formed by the end covers,
into the upper of which the liquid is allowed to flow from a supply tube, this
being a branch from an air vessel provided with a blow off tap or a pressure gauge,
and also with a pipe connection from the upper chamber.
The interior of the cylinder and the surfaces of the plates and all parts with
which the liquid can come into contact are tinned or nickel coated to prevent
metallic action.
The ends of the channels are provided, particularly the upper ends if the
apparatus be vertical, with a perforated plate to retain any solids which may pass
into the apparatus.
The centrally contracted sides of the cylinder where it comes into contact with
some of the perforated plates compel à detour or second filtering process of the
liquid before passing to the outlet passages into the outlet chamber.
My invention will be clearly understood by reference to the annexed drawings.

axles of a traveller for facility of shifting its position when found desirable.
A, cylinder or dium having ends contracted at the central parts B, feeding end
chamber to which the liquid to be filtered is supplied from the inlet C for distribu-
tion over the perforated plate D for checking the passage of impurities or solids
which may pass into the apparatus. E, E, are slots or openings in the cylinder or
of boxes fitted thereto and through which the liquid has free passage into spaces
so partitioned by perforated disc plates F, F, in pans that the liquid has to pass
through the perforations of the plates from one side to the other and in doing so
passes through the filtering media within each pair of plates, as indicated by the
arrows at Figure 1.
The filtering media may be of any known kind such as a woven fabric or canvas
kept extended by washed gravel, glass spheres or other material to keep the cloth
in contact with the plates, these being fitted within other slots of the end or bottom
of cylinder plate G and stayed at intervals by the bridge pieces H.
The liquid
after passing through the filter in zigzag manner, as indicated by the arrow>,
flows into a chamber I at the opposite end of the casing through other slots or
openings for collection in a branch pipe J up which it passes to a draw off casing K
for casking, bottling, or otherwise, the casing is provided with a blow off tap L
and a pressure gauge M for release of excess of gas supposing the liquid, say,
beer, be first charged with gas, in which case I provide the receiving chamber B
with a gas cylinder N also provided with a blow off tap P and pressure gauge R
in addition to a connection tube from the first receiving chamber B to put the gas
pressure of the filtering chamber in equilibrium.
The main cylinder is preferably in a single casting with, say, the back, and
after the plates, and the filtering media and the stays are in position the end cover $
is fitted in place and by the screws and fly-nuts T becomes reliably fixed.
The apparatus is mounted upon axles U for support on a carriage V with
wheels W, and the connection is easily effected with casks or bottling apparatus
by rubber or other tubing as found convenient.

page_text: The apparatus and the removable parts, say, of ion or copper are tinned or
nickled to preserve the liquid from injurious action.
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
1 claim is
1. The construction or arrangement of apparatus for filtering beers and other
liquids, as herein described and represented on the annexed diawings.
2. Affixing perforated plates and applying a filtering media thereto in the
manner represented on the annexed drawings.
3 Contracting the centres of cylindrical filter ends when such are employed
with internal perforated plates supplied with a filter fabric and distanced by
intermediate stays, and between which filtering media the liquid has passage to and
fro, and is discharged from opposite end holes out of the line of feed, as indicated.
