PROVISIONAL SPECIFICATION.
An Improved Refrigerator or Heater for Cooling or Heating Wort
or other Liquid.
1, CHARLES FREDERICK HUGHES-HALLETT, of 41 St. Stephen's Avenue,
Shepherd's Bush, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of this invention to be as follows:-
This improved refrigerator is made as follows: A vertical refrigerator, or heater
is made in or of a number of sections similar to the "Lawrence" refrigerators made
of corrugated plates, either placed as in the said Lawrence refrigerator, or back to
back, so as to present a tubular appearance inside or consisting of tubes. These
sections are placed parallel to each other at a suitable distance apart and between
each two sections a deflecting diaphragm with baffle plates or projections is placed,
which may be solid or also corrugated and hollow, or tubular, so as to cause the wort
to impinge against the whole of the corrugations &c., and thus get more cooling or
heating surface in a given area than by flat tubes placed edge to edge.
The sections are interchangeable and removable for cleaning purposes and
connected together by flanged D-shape or other bends, the joints of which are above
the level of the wort or liquid treated. The ends of the sections can be made
removable when required so that the interior can be cleaned.
The whole is enclosed in a "wood back" lined with copper, or made of brass or
gun-metal, and in addition to the wort or liquid inlet and outlet proper, a small
draining pipe is connected to and with each pair of sections. The corrugations &c.
can be placed so as to run vertically or horizontally as required, but the latter is
probably the best form; each corrugation may be drained separately. The liquor
to be treated flows over or about each section in succession until it issues from the
apparatus.
The advantage consists in obtaining a larger surface in a given area which is
usefully obtained by means of the diaphragms which cause the liquor to be treated
to impinge on the whole of the corrugated surface.

COMPLETE SPECIFICATION.
An Improved Refrigerator or Heater for Cooling or Heating Wort
or other Liquid.
I, CHARLES FREDERICK HUGHES-HALLETT, of 41 St. Stephen's Avenue,
Shepherd's Bush, in the County of Middlesex, Civil Engineer, 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 improved refrigerator or heater is made as follows:
A vertical refrigerator, or heater is made in or of a number of sections, similar to
the Lawrence refrigerators made of corrugated plates, or back to back, so as to
present a tubular appearance inside or consisting of tubes. These sections are
placed parallel to each other at a suitable distance apart and between each two
sections a deflecting diaphragm with baffle plates or projections is placed, which
nay be solid or also corrugated and hollow, or tubular so as to cause the wort to
impinge against the whole of the corrugations of the refrigerating or heating plates,
and thus get more cooling or heating surface in a given area than by flat tubes

placed edge to edge. The sections are interchangeable and removable for cleaning
purposes, and connected together by flanged D shape or other bends, the joints of
which are preferably above the level of the wort or liquid treated. The ends of the
sections can be made renovable when required, so that the interior can be cleaned.
The whole is enclosed in a "wood back lined with copper, or made of metal, and
. in addition to the wort or liquid inlet and outlet proper, a small draining pipe, is
connected to the space between each pair of sections. This draining pipe may also
be one and the same with the usual outlet pipe. The plates may be placed so that
the corrugations run at any angle or vertically or horizontally as required, but the
latter is probably the best form, and the spaces within the plates of each
refrigerating or heating section may be drained separately.
-
The liquor to be treated flows over or about each section in succession until it
issues from the apparatus.
The advantage consists in obtaining a larger surface in a conveniently shaped
space and is usefully obtained by means of the diaphragms which cause the liquor
to be treated to impinge on the whole of the corrugated surface.
In the annexed drawing
Fig. 1 is a side elevation partly in section of a form of machine made according
to this invention with the corrugations of the walls of the refrigerating or heating
chambers arranged horizontally.
Fig. 2 is a plan view thereof.
Fig. 3 is an elevation of part of the end of one of the said chambers.
Fig. 4 is a section through the same.
Fig. 5 is a horizontal section through the same showing parts of the ends of the
two adjacent chambers.
Fig. 6 is a sectional elevation and Fig. 7 a plan of a machine in which the
corrugations run vertically.
Referring to Figs. 1 to 5 each operative section or chamber in which the fluid
for effecting the heating or cooling passes, is composed of a corrugated plate or
plates a a fixed at their ends to and carried by two end frames 6b which are hollow
and preferably broader than the breadth of the corrugated chamber formed by the
plates a as will be more clearly seen in Fig. 5 so that each section may touch the
next on either side and enclose a space between the sectional interior of the said
end frames for passage of the wort or liquid to be treated. At or near the base of
one end of frame or chamber is a passage way c for the heating or cooling
operative liquid to pass into the space within the corrugated plates a, and at or near
the upper, end of the end frame or chamber which is at the other end of the
plate'a is a similar passage way for outlet of the heating or cooling liquid from
said space.
It will thus be obvious that the said liquid or operative fluid of whatever nature
in passing from the one end chamber to the other traverses the space, within the
corrugated plates a in a direction transverse to the corrugations. The two end
chambers of each section are connected respectively at their upper ends to the
adjacent end chambers of the two next sections, the one to that on the one side the
other to that on the other side, by means of the D or equivalent shaped pipes d d Fig. 2.
The first section and the last section however are provided with inlet e and outlet
respectively from one of their end chambers. It will be clear therefore that the
operative Huid entering at e, Fig. 2, traverses the interior of the first section I
passes to the next section. II and traverses the latter in the contrary direction
passes thence to the third section III and thus through all the sections successively
until it issues at the outlet f Fig. 2.
The tank or back in which. these sections are placed may be of the form and
construction shown in Figs. 1 and 2. The lateral extension of each end chamber b
forms an abutment for the next and secures the space between the sections when
they are firmly pressed together by the screws g and g'.
At the meeting edges of the end chambers bb, is cut a slot down the edge,
which lies towards the interior of the back. This slot forms a groove into which

page_text: i
the end of the diaphragm plates may be slid, or they may be otherwise secured.
These diaphragms stand vertically in the spaces between the sections and divide
each space into two. They are corrugated or provided with projecting baffle
plates extending from each face towards the corrugations in the plates a. These
diaphragms, which are easily removable by lifting out, rest so as to leave a free
passage way under their lower edges.
The wort or liquid to be treated enters at 7 and passes upward over the summit
of the nearest section, then descends between that section and the near side of the
diaphragm, ascends on the other side of said diaphragm in contact with the next
section, passes over the latter and so on till it reaches the outlet m where it is
carried off by pipe n.
For draining the spaces between the sections the pipe o is provided with
branches to cach said space.
P
This pipe may be omitted and pipe » made to serve
the purpose. A. valve may be used to close each branch and is removable after
the diaphragms have been. lifted. For this purpose the valve may be attached
to the diaphragms. r are air cocks.
In the construction shown in Figs. 6 and 7 the wort or liquid to be treated flows
horizontally back and forth around the sections, the latter must therefore be so
fixed as to leave passage way for the said liquid at the edges of the vessel at any
rate along one side. The diaphragm has its corrugations or battle plates arranged
vertically and the corrugations of the plates a are similarly arranged.
The
diaphragm fits into a groove at that side of the back which the sections do not
touch, while at the other end the passage way is left.
The passage of the liquid to be treated and the operating fluid will be apparent
from the arrows in the drawing and the equivalent lettering of the parts with those
fulfilling the same functions in Figs. 1 to 5. The apparatus as shown in Figs. 1, 3,
4 and 6 is conveniently placed at an angle as shown to give a fall to the liquid
treated.
I do not confine myself to any particular number of sections.
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. In a refrigerator or heater for wort or other liquid the combination of a series
of parallel vertical sections spaced from each other by the lateral extension of the
end chambers thereof and having in said spaces diaphragms with corrugations or
baffle plates, arranged so that the liquid to be treated and the heating or cooling
liquid pursue courses substantially as hereinbefore described.
a
2. In a refrigerator or heater for wort or other liquid the combination of a scries
of sections consisting of plates a, end chambers bb, connecting pipes d, diaphragms
between said chambers and a containing back; the plates being corrugated
horizontally, vertically or at any convenient angle, the diaphragms provided with
equivalently arranged corrugations or baffle plates and fitted to leave a passage way
for the liquid to be treated, and the attemperating sections arranged to permit
passage of said liquid over or alongside of them so that the latter liquid pursues a
course in relation to the diaphragms and attemperating sections substantially as
set forth.
