page_text: I, HENRI VUYLSTEKE, of 16, Rue du Boulet, Brussels, Belgium, Brewer's
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved means and apparatus connected with the
cooling of beers.
For the purpose of this invention, I arrange a series of pipes within other pipes
but of less length in head or end plates which separate the annular spaces between
cach series of pipes from the general area of the vessel in which such pipes are
arranged or nested.
The cooling medium has a return flow from the first entry tubes to the middle
or longer tubes terminating in a chamber from which the cooling agent passes
by an outside pipe back into another chamber from whence it circulates around
the shorter pipes of the series before passing away.
The beer to be cooled by the foregoing enters the vessel from the opposite end
and traverses in thin annular streams between the first and third set of pipes
into a chamber from which it can be drawn or flow from as desired.
The cooling medium entrance is into a chamber containing tubular socket.
as and extensions of the mid-length of pipes, and these sockets have side open-
ings for the passage of cooling agent into the annular spaces between their pipes
and of the longer pipes which are within them and by the ends being shut, the
cooling agent is compelled to flow along the central pipes to the end chamber
and to the branch pipe.
The end caps of the vessel are luted and are held thereto by screw bolts and
fly nuts as to be easily removable for cleansing or repairing purposes.
The rapidity of the passage of the cooling agent and also that of the beer to
be cooled can be regulated by taps, the plates to which they are connected and
by which the chambers are formed are held to the vessel in any suitable manner.
Dated this 2nd day of December 1898.

This invention relates to improved means and apparatus connected with the
cooling of beers.
For the purpose of this invention I arrange a series of pipes within other pipes
in head or end plates which separate the annular spaces between each series of
pipes from the general area of the vessel in which such pipes are arranged or
nested.
The cooling medium has a return flow from the first entry tubes to the middle
tubes terminating in a chamber from which the cooling agent passes by an out-
side pipe back into another chamber from whence it circulates around the other
pipes of the series before passing away.
The beer to be cooled by the foregoing enters the vessel from the opposite end
and traverses in thin annular streams between the first and third set of pipes
into a chamber from which it can be drawn or flow from as desired.
The cooling medium entrance is into a chamber containing tubular socket
as and extensions of the mid-length of pipes and these sockets have side open-
ings for the passage of cooling agent into the annular spaces between their pipes
and of pipes which are within them and by the ends being shut, the cooling agent
is compelled to flow along the central pipes to the end chamber and to the branch
pipe.
The end caps of the vessel are luted and are held thereto by screw bolts and
fly nuts as to be easily removable for cleansing or repairing purposes.
The rapidity of the passage of the cooling agent and also that of the beer to
be cooled can be regulated by taps the plates to which they are connected and
by which the chambers are formed are held to the vessel in any suitable manner.
My invention is clearly represented in the annexed drawings
Figure 1, vertical section
Figure 2, elevation.
A, A, are pipes connected to end plates B, B at opposite ends of a cylinder
or outer vessel C, the upper having a flanged ring D for the attachment of dome
shaped cover E by ily nuts F for easy removal for cleansing or other purpose.
The lower plate B₁ has a web flange G to fill up a space between the lower
flanged ring H and the upper flange I of an intermediate casting J secured to
it by fly nuts F¹ between the top plate K of which and the lower plate B¹ a
chamber is formed and provided with a pipe connection opening L.
The top plate K of the casting is provided with holes for wedge or cone fer-
ruled sockets M to rest in said holes in a water tight manner. The sockets M
have side holes N near their lower ends and their upper ends are prepared for
the reception of the lower ends of pipes P, P, the upper ends of which are closed
by caps or plugs or as represented.
The inner lower ends of the sockets M are screwthreaded for the reception of
thimbles Q, Q which serve as the continuations of pipes R and lead into a separ-
ate chamber formed by the partition S which is also part of the casting before
referred to and to which the thimbles Q, Q, are secured by nuts T, T.
The lower end of this casting has a flange J' for the affixture of an end cover
or closer U by fly nuts F, said cover U having a central opening V in com-
munication by pipe W with the lower part of the upper vessel C. The upper
portion of this vessel C has an overflow X.
The upper or dome shaped cover E has also a central opening Y and the
chamber a under it and between the top plate B forms the beer receiving cham-
ber which beer flows down the annular spaces b between the pipes A, P, in thin
annular streams or annular films and reassembles in the space or chamber e for
delivery by the outlet L.
The cooling water or other cooling agent enters the apparatus by the open-
ing & fills the chambers e then passes through the side holes N into the sockets M
thence up the annular spaces between the pipes P and R from which it over-

page_text: flows down the pipes R into the lower chamber and into the pipe W for entry
into the vessel Cup which it rises to the outflow or escape X.
Thus is may be observed that the cooling liquid or agent enters the apparatus
at the entry fills the chamber e and travels up the annular spaces f, f, between
the pipes P, R, exerting its cooling properties to the beers flowing down the
annular spaces 6 between the pipes A and P before the cooling agent passes
down the central pipes R into the chamber g to flow through the pipe W to the
upper chamber h or vessel C the cooling agent having what may be termed a
double or a treble circulation before reaching the exit while the beer has only
one simple travel it enters by the opening passes down or along the annular
spaces 6, 6, and leaves by the opening L. It is thus enclosed between two cur-
rents of the cold mixture.
The speed is rapid and this greatly increases the coefficient of convection of
the metal to the beer and consequently the transmission of heat also. The same
thing occurs with regard to the cold water.
The rapid speed of travel of the beer also prevents it from freezing or that any
sediment shall become deposited in the tubes.
The whole of the apparatus may be taken to pieces by unscrewing the nuts F
of the top cover E which can then be lifted off. The nuts are then discon-
nected and the tubes can be removed for cleaning if required; the apparatus
is therefore easily accessible in all its parts.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:
1. An apparatus for cooling beers the construction as represented on the an-
nexed drawings in which the beer to be cooled has a single flow in annular sheet
like form and between two flowing currents of the cooling agent which has a
double or treble flow, substantially as described.
2. In an apparatus for cooling beers the particularly arranged group of three
pipes of different lengths and in connection with different chambers through
and from which the cooling agent has motion with a transfer from the lower
chamber to the upper chamber before escaping, as described and substantially
as indicated.
3. The construction of refrigerating apparatus in three parts attachable to each
other and forming three distinct vessels so connectable and provided with groups
of pipes that the cooling agent has first an up flow in annular passages, secondly
a down flow in column form and thirdly in bulk through the upper chamber and
circulating round the pipes therein as explained with reference to the annexed
drawings.
