PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating or Cooling Air or Water
and other Gases or Liquids.
I, WILLIAM TATTERSALL, of 90, Arden Terrace, Accrington, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in apparatus for heating or cooling air or
water or other gases or liquids and its object is to simplify the construction of this
class of apparatus.
For this purpose I employ a number of square plates placed parallel to each other
or side by side a suitable distance apart. These plates are connected together in
pairs by two opposite edges which may be termed their vertical edges to distinguish
them from the edges at right angles thereto. The horizontal edges of each pair
of plates are connected in a similar manner to the horizontal edges of the pair of
plates on either side. The edges of the plates to be joined together are preferably
bent towards each other and flanged for that purpose and such plates may be
made interchangeable.
By this simple construction two series of passages are formed at right angles to
each other arranged alternately and perfectly separated. They may be made of
any desired width and any relative proportion. The heating or cooling medium is
confined to one series of passages and the gas or liquid to be heated or cooled is
drawn or forced through the other.
The simple and interchangeable construction allows the apparatus to be readily
reduced to sections to facilitate transit.
Two or more apparati may be arranged side by side or one above the other.

Improvements in Apparatus for Heating or Cooling Air or Water
and other Gases or Liquids.
I, WILLIAM TATTERSALL, of 90), Arden Terrace, Accrington, in the County
of Lancaster, 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 invention relates to improvements in apparatus for heating or cooling air
or water or other gases or liquids and its object is to simplify the construction of
this class of apparatus.
The
For this purpose I employ a number of rectangular plates placed parallel
to each other or side by side a suitable distance apart. These plates are
connected together in pairs by two opposite edges which may be termed their
vertical edges to distinguish them from the edges at right angles thereto.
horizontal edges of each pair of plates are connected in a similar manner to the
horizontal edges of the pair of plates on either side. The edges of the plates to
be joined together are preferably bent towards each other and flanged for that
purpose and such plates may be made interchangeable.
By this simple construction two series of passages are formed at right angles to
each other arranged alternately and perfectly separated. They may be made of

page_text: any desired width and any relative proportion. The heating or cooling medium is
confined to one series of passages and the gas or liquid to be heated or cooled is
drawn or forced through the other.
This simple and interchangeable construction allows the apparatus to be readily
reduced to sections to facilitate transit.
Two or more apparatı may be arranged side by side or one above the other.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, is an elevation of an apparatus constructed in accordance with my
invention.
Figure 2, is a similar side view of one of the plates shown separate.
Figure 3, is a full view of said plate.
Figure 4, is a section of one of the ends on a larger scale.
Figure 5, is a full view of one corner of a plate illustrating a convenient way
of cutting the corners of the plate previous to bending it so as to leave projecting
pieces on the corners to facilitate the attachment of an Langle iron along each
corner of the apparatus to fully separate the two sets of passages and to form the
foundation (if required) for the attachment of a heating, cooling, receiving or
exhausting chamber.
Figure 6, is a similar view of the corner after the plate is bent.
Figure 7, is an edge view of the same.
Figure 8, is a similar view to Figure 6 with the said angle iron shown in position
in section.
Figure 9, is an edge view similar to Figure 7 of two plates with the angle iron
attached in this manner.
The plates after having a piece of suitable size taken out of each corner
according to the width of the passages have each pair of parallel sides A, A
and B, B bent over to form the spacing or distance pieces C (half the width of the
passages) and the connecting flanges D. One pair of parallel sides being bent in
one direction and the other pair in the reverse direction. To form the two series
of passages the plates are placed face to face as shown in Figure 1 and the flanges D
which meet each other riveted or otherwise secured together.
Any suitable method of filling in the corners to completely separate the two sets
of passages may be employed and also for the attachment of a heating, cooling,
receiving or exhausting chamber or chambers may be employed but Figures 5 to 9
illustrate a convenient method.
Instead of cutting a rectangular piece from each corner of the plate the corners
are cut as shown Figure 5 and the piece thus left at each end of the distance
pieces C is divided by the diagonal line F. Thus when the plates are bent this
leaves a triangular piece G projecting at each end of each of the spacing pieces C to
which the angle iron H is riveted along each corner of the apparatus.
my
said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what
I claim is :
The particular construction of heating or cooling apparatus formed of a number
of plates having the parallel edges of each plate bent over to meet the similarly
bent edges of the plates on each side to form the spacing and connecting medium,
substantially as herein shown and described.
