PROVISIONAL SPECIFICATION.
An Improved Plate for Use by Confectioners and others for Cooling
or Heating Substances.
I, JAMES LUKE COLLIER, of Wellington Works, Rochdale, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a hollow plate adapted to have water or steam or other
cooling or heating fluid passed through it and designed for use by confectioners
and others for cooling or heating substances placed upon it, the object of my
invention being to so construct the plate that the maximum of cooling or heating
efficiency shall be obtained from the cooling or heating medium.
My improved plate, which is preferably made of cast iron, has formed in the
space between the top and bottom surfaces a number of ribs or partitions of a
length somewhat shorter than the length or breadth of the plate, the openings
formed by thus shortening the said partitions being at the opposite ends of adjacent
partitions, whereby the fluid introduced into one end of the space within the plate
will have to flow backwards and forwards across the plate, in passing from one
end to the other thereof, as many times as there are partitions.
In practice the opposite sides of the plate against which the partitions abut are
made removable in order to afford access to the passages between the partitions
for purposes of manufacture and for cleaning the same if required. The inlet
and exit openings for the fluid may be at the bottom of the plate or on the sides
or ends.
I find it advantageous to provide my improved plate with a rim or flange around
its outer edge but as in some cases a perfectly flat surface is required I make this
rim partly or wholly detachable when necessary.
By making my improved plate of cast iron in one casting in the manner herein-
before described I find that it is much stronger and less liable to get out of level
than two plates bolted together as heretofore constructed when subjected to
pressure or heat.

An Improved Plate for Use by Confectioners and others for Cooling
or Heating Substances.
I, JAMES LUKE COLLIER, of Wellington Works, Rochdale, 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 :-
My invention relates to a hollow plate adapted to have water or steam or other
cooling or heating fluid passed through it and designed for use by confectioners
and others for cooling or heating substances placed upon it, the object of my

page_text: invention being to so construct the plate that the maximum of cooling or heating
efficiency shall be obtained from the cooling or heating medium.
My improved plate, which is preferably made of cast iron, has formed in the
space between the top and bottom surfaces a number of ribs or partitions of a
length somewhat shorter than the length or breadth of the plate, the openings
formed by thus shortening the said partitions being at the opposite ends of adjacent
partitions, whereby the fluid introduced into one end of the space within the plate
will have to flow backwards and forwards across the plate, in passing from one end
to the other thereof, as many times as there are partitions.
In practice the opposite sides of the plate against which the partitions abut are
made removable in order to afford access to the passages between the partitions
for purposes of manufacture and for cleaning the same if required. The inlet
and exit openings for the fluid may be at the bottom of the plate or on the sides
or ends.
1 find it advantageous to provide my improved plate with a rim or flange around
its outer edge but, as in some cases a perfectly flat surface is required, I make this
rim partly or wholly detachable when necessary.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a plan of a plate constructed according to my invention:
Figure 2 is a horizontal section of the same:
Figure 3 is a section on the line 3-3 of Figure 1:
Figure 4 is a section on the line 4-4 of Figure 1.
a is the top surface of the plate, and 6 the bottom surface of the same; c, c are
the ribs or partitions forined in the space between the two surfaces a and b, the said
ribs being somewhat shorter than the breadth of the plate. The two surfaces a
and and the partitions c, c are preferably cast in one piece. The ribs or
partitions c, c extend alternately from the opposite sides d, e of the plate so that
the openings left between the ends of the partitions c and the sides of the plate
are at opposite ends of adjacent partitions as shewn clearly in Figure 2.
f is an opening at one end of the plate for the introduction of the cooling or
heating fluid, and g is a similar opening at the other end of the plate through which
the said fluid can flow away after passing backwards and forwards in a zig-zag
manner across the plate.
The sides d, e are made separate from the rest of the plate to which they are
screwed, as shewn clearly in the drawing, in order that they may be removed to
afford access to the partitions.c, c when desired.
In the plate shewn in the drawing, the rim h at each of the opposite sides d, e is
shewn cast in one with the body of the plate whilst the rim i at each end of the
plate is made separate from the same and is secured in position by means of screws
so that it can be detached from the plate when desired.
By making my improved plate of cast iron in one casting in the manner herein-
before described I find that it is much stronger and less liable to get out of level
than two plates bolted together as heretofore constructed when subjected to
pressure or heat.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. A plate for use by confectioners and others for cooling or heating substances,
wherein a space is left between the top and the bottom surfaces of the same and a.
number of ribs or partitions are formed in the said space, substantially as, and in
the manner, hereinbefore described.
2. In a plate of the kind described in Claim 1, forming the sides against which
the ribs abut detachable from the plate and the rim around the edge of the upper
surface of the plate partly or wholly detachable, substantially as, and for the
purpose; hereinbefore described.

page_text: 3. The manufacture and use of the improved plate for cooling or heating
substances herein before described and illustrated in the accompanying drawing.
