of Thurgovia, in Switzerland do hereby declare the nature of this invention to be as
follows:

This invention has reference to the clarifying of beer wine or other fermented or
fermenting liquids and may be employed with advantage for the separation of the
clouding constituents (such as yeast, gluten, and the like) in beer and wine as it
enables the use of "clearing chips" (Klarspahne) and other organic clearing media
(which are often the cause of these liquids becoming partially or wholly spoiled) to be
dispensed with.
According to this invention there is introduced into the liquid to be clarified porous
bodies of burned calcined or baked clay or loamy earth or of neutral porous mineral
substance of volcanic origin.
The substances introduced have no chemical action upon the liquids to be clarified ;
the clarifying bodies should be well soaked and washed before use. They afford to
the brewer and wine producer a clean neutral medium which can be used over and
over again and which may be cleaned or purified by being burned or calcined after
use.
These clearing or clarifying bodies may be of any shape, but it is advantageous to
employ very porous forms and such as have a comparatively large surface and can be
easily cleaned
One form that may be employed with advantage is a hollow cylinder having its
inner and outer surfaces corrugated serrated or fluted
Fig. 1 illustrates an arrangement of three such cylinders connected, the clarifying
body thus formed having a rough and large surface.
This form is designed to be introduced into vats, casks, barrels or other receptacles
through doors or openings.

Clarifying bodies of the kind above referred to, are, after being moulded, dried as
slowly as possible; they are then well burnt, after which they are thoroughly soaked
and washed so that no soluble substances shall remain in them.
To obtain an especially porous clarifying body, burnt clay is pulverized and mixed
with moist clayey or loamy earth specially prepared for this purpose, and the mixture
is suitably moulded and burned.
In using the bodies they are allowed to remain in the liquid to be clarified until the
clarifying proces is completed the said process being usually effected by the separa-
tion of the clouding particles of yeast, gluten &c. and the deposition of the same
upon the surface of the clearing bodies introduced, in a manner similar to that which
is designed to be effected by the employment of organic clearing media (clearing
chips &c.

and other Fermented or Fermenting Liquids.
We, ADOLF GUSTAV JERIOKA, Brewery Technologist, at Gottlieben, Canton of
Thurgovia, in Switzerland, and AUGUST EGGIMANN, Architect, at Ermatingen, Canton
of-Thurgovia, in Switzerland 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 reference to the clarifying of beer wine or other fermented or
fermenting liquids and may be employed with advantage for the separation of the
clouding constituents (such as yeast, gluten and the like) in beer and wine as it
enables the use of "clearing chips" (Klarspahne) and other organic clearing media
(which are often the cause of these liquids becoming partially or wholly spoiled) to be
dispensed with..
According to this invention there is introduced into the liquid to be clarified porous
bodies of burned calcined or baked clay or loamy earth or of neutral porous mineral
substance such as mineral of volcanic origin.
Porous inorganic substances according to this invention are particularly applicable
for replacing the above mentioned organic clearing agents in the manufacture of
wine and beer.
The substances introduced have no chemical action upon the liquids to be clarified;
the clarifying bodies should be well soaked and washed before use They afford to
the brewer and wine producer a clean neutral medium which can be used over and
over again and which may be cleaned or purified by being burned or calcined
after use.
These clearing or clarifying bodies may be of any shape but it is advantageous to
employ very porous forms and such as have a comparatively large surface and can
be easily cleaned.
One form that may be employed with advantage is a hollow cylinder having its
inner and outer surfaces corrugated, serrated or fluted.
Referring to the drawing filed with our Provisional Specification:
Fig. 1 illustrates an arrangement of three such cylinders connected, the clarifying
body thus formed having a rough and large surface.
This form is designed to be introduced into vats, casks, barrels or other receptacles
through doors or openings.
Fig. 2 illustrates in elevation and partial section a clarifying body which is designed
to be introduced through the bung hole of the cask containing the liquid to be
clarified.
Fig. 3 is an end view. a is a wire by means of which this clarifying body b is
introduced into the liquid
Clarifying bodies of the kind above referred to (burned clay bodies) are, after
being moulded, dried as slowly as possible; they are then well burnt, after which they
are thoroughly soaked and washed so that no soluble substances shall remain in
them.

page_text: To obtain an especially porous clarifying body, burnt clay is pulverized and
mixed with moist clayey or loamy earth and the mixture is suitably moulded and
burned.
In using the bodies they are placed and kept in the liquid to be clarified until the
clarifying process is completed the said process being usually effected by the separa-
tion of the clouding particles of yeast, gluten &c. and the deposition of the same upon
the surface of the clearing bodies introduced, in a manner similar to that which is
designed to be effected by the employment of organic clearing media (clearing
chips &c.)
The porous bodies herein before described and shewn in the drawing may also be of
any other suitable form; the larger the surface, the better the action of the body
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what
we claim is .—
1. The hereinbefore described method or process of effecting the separation from
fermented or fermenting liquids of yeast, gluten and other clouding matters or con-
stitutents, the said method or process consisting in the introduction into the liquid of
a burned porous body or of burned porous bodies of clay or loamy earth or the
like.
2. The use for effecting the separation of yeast, gluten and other clouding matters
or constituents from fermented or fermenting liquids, of a burned porous body of
clay, loamy earth or the like, having a plain or serrated surface, and with or without
hollow spaces or channels.
