A Refrigerative show
I, ROBERT KENNETH BALCARRAS, of 14 Lower Ormond Quay, Dublin, in the
County of Dublin, Engineer, do hereby declare the nature of this invention to be
as follows:- .
My invention relates to a refrigerative show-case.
The object of my said invention is to provide a refrigerator suitable for meat or
other articles of food for example and which, unlike those heretofore employed,
does not hide its contents from view while at the same time it serves to keep said
contents perfectly cool.
According to one method of carrying out my invention I construct a show-case
the sides and back of which are made double and packed with non-conducting
material. The front of the case is preferably made of plate-glass which may be
The ice or the
supported upon suitable legs furnished with castors if desired.
like for maintaining a low temperature inside the case is preferably contained
in a tray placed in an ice-chamber which forms the top portion of said case
and which is separated by a perforated portion from the lower portion or show-
case proper. The ice chamber is provided with proper ventilation apertures
where necessary. I make the tray with one side higher than the other so that
a circulation of cold air is maintained in one direction through the ice-chamber
and case.
The drain pipe to carry away the water from the ice tray passes
down one angle of the case and then round the four sides of the bottom before
being finally led out.
The case proper, that is to say, that portion below the ice chamber is of course
made as air-tight as possible so as to prevent the efflux of cold air therefrom,
I preferably provide a suitable sun-blind which can be drawn out or down to shade
the case when necessary.
I provide the case with suitable hooks, shelves or the like for displaying the
goods, and I sometimes line the sides with mirror-glass so as to increase the
attractiveness of the same. A door is fitted in one or more of the sides to provide
access to the interior of the case.
I make the case in readily separable sections so that when the case is not required
it may be taken to pieces and stowed away in a small space.
My improved show-case will be found very suitable for butchers, fishmongers
and the like who have hitherto been accustomed to put their goods out of sight
in a cold room during hot weather, and have thus been deprived of the opportunity
of displaying the same to advantage.

page_text: I, ROBERT KENNETH BALCARRAS, of 14 Lower Ormond Quay, Dublin, in
the County of Dublin, 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 refrigerative show-case.
The object of my said invention is to provide a refrigerator suitable for meat or
other articles of food for example and which, unlike those heretofore employed,
does not hide its contents from view while at the same time it serves to keep the
contents perfectly cool and fresh. The air in the case is cooled by means of ice or
other suitable materials placed in a chamber in the upper part of the case.
My improved refrigerative show-case is adapted especially to stand in a shop
window.
In order that my invention may be clearly understood I will now describe the
same with reference to the accompanying drawings in which
Figure 1 is a front elevation of a part of my refrigerative show-case.
Figure 2 is a vertical longitudinal section of the same on the line Y Y of
Figure 5, looking in the direction of the arrow.
Figure 3 is a vertical transverse section on the line X X of Figure 2, looking
in the direction of the arrow.
Figure 4 is a top plan and
Figure 5 is a broken ground plan of my refrigerative show-case.
The sides A A, back A' and top A² are made double the cavities therein being
filled and tightly packed with non-conducting material preferably consisting of
charcoal and sawdust in about equal proportions as shown at A A³ Figures 2, 3
and 5. The case is provided with a plate glass front B so that the contents shall
be visible. The whole case which may be made ornamental if desired may be
supported on suitable legs which can also be furnished with castors if desired. In
the figures the case is shown without either.
The ice blocks C' or the like for maintaining a low temperature inside the case
are contained in a tray C¹ which rests on transverse beams C° C and is placed in
the ice chamber C. This chamber is lined with zinc throughout, and forms the
top portion of the case being separated by a partition D from the lower portion or
the show-case proper.
The partition D is provided with an opening or with
openings at D¹ to allow of the passage of air therethrough as will be hereinafter
described.
I make the ice-tray C' with one side C³ higher than the other side C* so that a
circulation of the air is maintained in one direction through the ice chamber and
lower case.
The two sides C3 C4 of the ice tray are preferably made double and
packed similarly to the walls with non-conducting material. The direction of the
air-current is shown by the arrows.
The case proper E, that is to say, that portion below the ice-chamber C is
constructed to prevent the escape of the cold air therefrom.
I provide the case E, round the two sides and back thereof, with hollow
shelves E E E preferably made of copper or zinc, which may be supported on
ornamental brackets or pillars E' E'. I also provide another hollow shaft E³
resting on the floor boards E' which boards are preferably covered with lead E¹º.
Hooks E E may also be provided in the floor D of the ice-chamber C so that
meat or the like may be suspended in the refrigerating chamber E.
The interior of the sides and back of the case E is provided with mirrors E³ E'
to add to the attractiveness of the case.

page_text: A door E is provided in the side of the case for the insertion and removal of the
rticles of food or the like.
The ice chamber C is also provided with several doors, that is to say F F are
wo large flap doors which can be opened to allow of filling and replenishing
he ice chamber with ice.
F¹ is a ring provided on one of the doors to facilitate the opening of the same.
G is a small door also provided in the top of the ice chamber which may be opened
occasionally if desired to let out any foul or obnoxious gases or odours from the
case. All the doors are preferably provided with rubber tubing or the like
round their edges to render the same air tight. The water from the melting
ice is drained off from the ice tray C¹ by a pipe H. H' is a perforated cover
over the outlet opening in the ice tray, to prevent any rubbish passing down
the pipe H. The cold water from the melting ice flows down the pipe Hand
into the top hollow shelves E¹ E¹ E¹, and thence by another pipe passes into
the lower hollow shelf E³ and finally rises up a stand pipe to an outlet tap H³
which is above the level of the upper shelves. By this means the shelves are
kept cool, being always full of cold water.
The air warmed by contact with the articles in the lower part of the case
rises up through the opening or openings D¹ in the partition D, passes over
the higher side of the ice tray C³ and then over the ice which cools it. It
then passes down a passage L between the outer and inner walls of the case
and again enters the case through an opening or openings E' under the side
mirror E³.
The case is provided with a roller or other sun-blind K, fixed in the cornice M
at Figure 3, which may be drawn out or down to shade the case when necessary.
I preferably make the case in readily separable sections so that when it is
not required to be in use, it may be taken to pieces and stowed away in a
small space.
My improved refrigerative show-case will be found very suitable for butchers,
fishmongers and the like who have hitherto been accustomed to remove their
goods to a cold room during hot weather and have thus been deprived of the
opportunity of displaying the same to advantage.
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 refrigerative show-case having an upper chamber in which the ice or
other refrigerating material is placed, and a lower chamber provided with hollow
shelves through which the water from the melting ice drains, substantially as
shown and described.
2. A refrigerative show-case constructed substantially as shown and described
with reference to the accompanying drawings.
