PROVISIONAL SPECIFICATION.
Improvements in and relating to Ice or Cooling Tanks.
I, THOMAS FROST, of 49, Sadler Gate, Derby, in the County of Derby, Pork
Butcher, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to derive the greatest possible benefit from the
freezing mixture in an ice tank, my said invention referring principally to tanks
which are placed inside apartments for cooling the atmosphere of same, it may
however be applied to other forms of tanks if desired.
In carrying out my said invention I employ a tank to contain the ice and salt
or other freezing mixture, of any suitable shape with either closed or open top
and a stay or stays across same to strengthen it, inside this tank are arranged a
number of tubes running from one side to the other, from end to end or from top
to bottom, these tubes have open ends on the outside and passing through the heart
of the tank much greater cooling surfaces are provided and consequently more
benefit derived from the contents of the tank, the tubes may slope slightly outwards
to drain any moisture away.
anl
The tank is provided with fixed or removable legs or feet, to enable it to stand
in any convenient position, a liquid receiver is placed below the tank and projects
slightly all round to catch any moisture running down the sides of same;
overflow is placed at or near the top of the tank, the outlet of which also com-.
municates with the aforesaid liquid receiver. A tap may be provided at or near
the bottom of the tank for convenience in emptying same, the said tap being also
arranged to empty into the said liquid receiver which is preferably made to slope
to one point, such as the centre, from which there passes a trapped waste pipe
communicating with the drain or sewer.
By arranging a liquid receiver as described and having the tap and overflow
communicating therewith I am enabled to drain all the waste liquid away down
the one waste pipe from the liquid receiver.

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of my invention is to derive the greatest possible benefit from the

which are placed inside apartments for cooling the atmosphere of same, it may
however be applied to other forms of tanks if desired.
In describing my invention reference will be had to the accompanying sheet
of drawings upon which Figure 1 is a sectional elevation of a tank constructed
according to my invention and Figure 2 is a plan of the same
Figure 1.

As my improved tank may be applied to a number of different forms of refriger-
ating chambers I have not shewn any particular chamber but simply the tank
and its parts.
In carrying out my said invention I employ a tank A to contain the ice and
salt or other freezing mixture, of any suitable shape with either closed or open top
and a stay or stays across same to strengthen it, inside this tank are arranged a
number of tubes B, B¹ running from one side to the other, from end to end or
from top to bottom, these tubes have open ends on the outside and passing through
the heart of the tank much greater cooling surfaces are provided and consequently
more benefit derived from the contents of the tank, the tubes B' from side to side
or from front to back may slope as shewn to drain any moisture away. The tank
is provided with fixed or removable legs or supports C to enable it to stand in any
convenient position, a liquid receiver or gutter D is placed below the tank and
projects slightly all round to catch any moisture running down the sides of same;
an overflow E is placed at or near the top of the tank, the outlet of which com-
municates with the aforesaid liquid receiver or to the waste gulley F therefrom.
A tap G may be provided for convenience in emptying same, the said tap being
also arranged to empty into the liquid receiver or into the waste gulley F from
same; the liquid receiver is preferably made to slope to one point such as the
centre, or as shewn upon the drawings to one corner from which it passes to a
gulley or the like F communicating with the drain or sewer the said gulley being
trapped at F after the overflow and drain pipe have been connected to it.
By arranging a liquid receiver as described and having the tap and overflow
communicating with the waste therefrom I am enable to drain all the waste liquid
away down the one pipe from the gulley and by trapping it as already stated
prevent the inlet of any warm air or offensive gases from the sewer.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is;-
-
In an ice or cooling tank the employment of tubes BB¹ a liquid receiver or.
gutter D and waste pipe or gulley F in combination with overflow E, drain cock G.
and trap F¹ substantially as described and illustrated.
