PROVISIONAL SPECIFICATION.
Improvements in "Pasteurising " Apparatus.
I, ARTHUR REGEL, of Schoningen, Brunswick, Germany, Brewer, do hereby declare
the nature of this invention to be as follows:-
The invention relates to pasteurising apparatus that may be advantageously employed
for beer, wine, and other beverages, and which possesses the advantages of being
readily operated, allowing of continuous working, and being compactly arranged.
Referring to the annexed drawings,
Fig. 1 shows apparatus according to this invention partly in vertical section, and
partly in external elevation.
Fig. is a plan.
Fig. 3 shows a modified arrangement, in which four warming or cooling cylinders
surrounded by a common shell or casing are used.
In the arrangement shown in Figs. 1 and 2, there are two cylinders C C³, closed at
their upper and lower ends by means of covers and bottoms or heads, and whose lower
ends are connected by unions ee, with a pipe a through which latter the beer or other
liquid to be pasteurised, (hereinafter called beer) is conveyed from the cask A to. the
cylinder.
Each cylinder CC is surrounded by a shell or casing B B' which encloses a
hollow space that is employed as a warming or cooling space. In each cylinder. C, C¹
there is a piston D, D', operated by air pressure as hereinafter described.
These pistons are provided with rubber rings which serve to make a tight joint
between the pistons and their cylinders. Each piston carries a thermometer c,, the
bulb of which passes through the piston and serves to indicate the temperature in
the space below the piston, also a rod u which serves to set an electrical alarm or
signal u into operation when the piston has reached its highest position in its
cylinder.
Each piston is further provided with a cock p which serves to allow of the escape of
the air from the space in the cylinder below the piston.
The top cylinder cover is furnished with a dome of glass or other transparent
material into which the thermometer o can enter, and thus enable the thermometer to
be observed. There is also provided on the cover the electrical alarm or signalling
device u¹ which is operated as described by means of the rod u and the piston. The
upper cylinder cover also carries a pressure gauge n n'.
The upper part of each cylinder is connected with a pump or other device capable
of supplying compressed air, by a pipe.g' having three-way cocks q, q.
In the pipe a are cocks with sight-glasses 1, of which is further provided with a
pressure gauge for the purpose of indicating the air pressure. y is an air escape cock,
and fa cock for enabling the liquid from the cylinder to flow into a froth-preventing
device. The cylinders C, C are arranged on stands.
The method of using the apparatus is as follows:-
1
The beer to be pasteurised, contained in the cask A, is, by means of compressed air
supplied by the pipe a', caused to pass through the draw off cock a², pipe a, valve l,
and cock b, and union c into the cylinder C.
By the pressure of the beer, the piston D is moved upward, after the air present in
the cylinder has escaped by opening the cock y.
When the piston has reached its highest position, this is indicated by the electrical.
alarm or signalling device u u¹.
The space between the cylinder C and the shell or casing B is then heated to
65° Reaumur = 82° Celsius = 178° Fahr.
This is preferably effected by means of steam which enters by the valve r and passes

page_text: off by a pipe with a valve t, whilst the pipes which is also provided with a valve
carries off the water of condensation of the steam.
Whilst beer is being forced into the cylinder (, and during the heating process, the
cock dis closed.
When
a temperature of 65° R. has been reached, the cock d is opened, and the
heated beer passes out of the cylinder C through the unions cand e into the
cylinder C¹.
In order to cause the piston D' to rise in the cylinder C³, the three-way cocks
are opened, and air is allowed to pass by the air pipe q¹ into the cylinder C above the
piston D, so as to exert a pressure upon this piston D which moves downward; and
the piston D' is forced into its highest position by the inflowing beer.
When this has been effected, which is indicated by means of the alarm or signalling
apparatus u u', the cock d is closed, and the heated beer is cooled first by means of
warm water, then by means of ice cold water which enters and leaves the space between
the shell or casing B¹ and cylinder C, through pipes rt similar to those for the steam
in the cylinder, until the thermometer o in the piston D¹ indicates the temperature
of 4° R. = 5° C. = 41° F.
The cock is then opened, and the upper end of the cylinder brought into
communication with the compressed air flowing through q', after the cock q has been
opened, whereupon the beer is conveyed into the froth-preventing device g, and thence
through the draw off cock and pipe into bottles or casks.
As the cylinders CC with their shells or casings B, B¹, are of identical construc-
tion, each cylinder may be employed either as a cooling or a heating apparatus.
When the cylinders are employed separately for beating and for cooling, as above
described, the apparatus may be operated continuously during the downward movement
of the piston D¹ in the cylinder C, the piston D being carried up, and fresh beer being
passed into the cylinder C.
In the arrangement shown in Fig. 3, several cylinders are surrounded by a common
shell or casing, and can all be alternately heated and cooled. By this arrangement the
cooling and the heating surfaces, and the cooling and the heating liquids can be better
utilized.

COMPLETE SPECIFICATION.
Improvements in "Pasteurising" Apparatus.
I, ARTHUR REGEL, of Schoningen, Brunswick, Germany, Brewer, 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 invention relates to pasteurising apparatus that may be advantageously
employed for beer, wine, and other beverages, and which possesses the advantages
of being readily operated, allowing of continuous working, and being compactly
arranged.
Referring to the drawings filed with my Provisional Specification
:-
Fig. 1 shows apparatus according to this invention partly in vertical section, and
partly in external elevation.
Fig. 2 is a plan.
Fig. 3 shows a modified arrangement, in which four warming or cooling cylinders
surrounded by a common shell or casing are used.
In the arrangement shewn in Figs. 1 & 2, there are two cylinders C C₁, closed at
their upper and lower ends by means of covers and bottoms or heads, and whose lower
ends are connected by unions cc, with a pipe a through which latter the beer or other
liquid to be pasteurised, (hereinafter called beer) is conveyed from the cask A to the
cylinder.

device u¹ which is operated as described by means of the rod u and the piston. The
upper cylinder cover also carries a pressure gauge n n¹.
The upper part of each cylinder is connected with a pump or other device capable
of supplying compressed air, by a pipe q' having three-way cocks q, q.
In the pipe a are cocks with sight-glasses 7, of which is further provided with
a pressure gauge for the purpose of indicating the air pressure. y is an air escape
cock, and a cock for enabling the liquid from the cylinder (³ to flow into a froth-
preventing device. The cylinders C are arranged on stands.
The method of using the apparatus is as follows
The beer to be pasteurised, contained in the cask A, is, by means of compressed
air supplied by the pipe a', caused to pass through the draw off cock a², pipe a,
valve, and cock b, and union e into the cylinder C.
By the pressure of the beer, the piston D is moved upward, after the air present in
the cylinder has escaped by opening the cock y.
When the piston has reached its highest position, this is indicated by the electrical
alarm or signalling device u u¹.
The space between the cylinder C and the shell or casing B is then heated to
65° Reaumur = 32° Celsius 178° Fahr.

This is preferably effected by means of steam which enters by the valve r and
passes off by a pipe with a valve t, whilst the pipe s which is also provided with a
valve carries off the water of condensation of the steam.
Whilst beer is being forced into the cylinder C, and during the heating process,
the cock d is closed.
When a temperature of 65° R. has been reached, the cock d is opened, and the
heated beer passes out of the cylinder C through the unions cand e into the
cylinder C.
In order to cause the piston D¹ to rise in the cylinder C, the three-way cocks g
are opened, and air is allowed to pass by the air pipe q¹ into the cylinder C above
the piston D, so as to exert a pressure upon this piston D which moves downward;
and the piston D is forced into its highest position by the inflowing beer.
When this has been effected, which is indicated by means of the alarm or
signalling apparatus u u', the cock d is closed, and the heated beer is cooled first by
means of warm water, then by means of ice cold water which enters and leaves the
space between the shell or casing B¹ and cylinder C₁, through pipes rt similar to
those for the steam in the cylinder C, until the thermometer o in the piston D'
indicates the temperature of 4° R. = 5° C. = 41° F.
The cock is then opened, and the upper end of the cylinder C¹ brought into
communication with the compressed air flowing through q', after the cock q has been
opened, whereupon the beer is conveyed into the froth-preventing device g, and
thence through the draw off cock and pipe into bottles or casks.
As the cylinders CC with their shells or casings B B₁, are of identical construction,
each cylinder may be employed either as a cooling or a heating apparatus.
When the cylinders are employed separately for heating and for cooling, as above

page_text: described the apparatus may be operated continuously during the downward move-
ment of the piston D' in the cylinder C, the piston D being carried up,, and fresh
beer being passed into the cylinder C.
In the arrangement shown in Fig. 3, several cylinders are surrounded by a common
shell or casing, and can. all' be alternately heated and cooled. By this arrangement
the cooling and the heating surfaces, and the cooling and the heating liquids can be
better utilized.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Apparatus for pasteurising beer and other liquids, comprising two cylinders C, C¹¹
surrounded by cooling or heating shells or casings, and provided with pistons D, D
adapted to be moved up and down by beer or other liquid when introduced into the
cylinder by the action of compressed air, and with pipes by which the interiors of
the cylinders can be connected with a cask, whose contents are to be pasteurised,
substantially as described and illustrated.
2. The modified construction of pasteurising apparatus for treating beer and other
liquids, in which several cylinders C or C, are surrounded by a single shell or casing
common to them all, as herein before described and illustrated in Fig. 3 of the drawings
