Improvements in Apparatus for Producing Blooks of Transparent Ice.
PHILIP BORN 11 Queen Victoria Street, London in the County of Middlesex
Manufacturers Agent, do hereby declare the nature of this invention to be as
follows:-
-
This invention consists of a cold water tank A a boiler or vessel B and a
freezing vessel C. The two vessels B and C are connected by means of a tube D, the
interior of this tube D consists of two seperate passages or canals a and d.
The tube D is fixed to an axle E as shown in Fig. 4 which turns and rests in
bearings F and F as shown in Fig. 4 and can be turned by means of the spiral
gearing by which means the vessels B and C can be brought in any desired position
as shown in Fig. 1. 2. 3.
The manipulation to produce ice is as follows-fill the tank A with cold water,
place the vessels B and C in the position shown in Fig. 1, fill the vessel B about full
with a full saturated solution of Ammonia, place under the vessel B a gas, petroleum,
charcoal or any other suitable heating apparatus and light the same.
After the air has escaped through the small opening fat the top of the tube D
as shown in Fig. 1, close the opening by means of a screw stopper, the ammonia gas
arising out of the solution will now pass through the canal a of the tube D into the
freezing vessel C in which it condenses and becomes fluid.
To prevent parts of the fluid solution being drawn into the canal a through its
boiling action, a metal guard 6 and several perforated plates or sieves b¹ are fixed in
the cover of the vessel B. The opening 9 as shown in Fig. 4, permits the introduction
of a Thermometer into the vessel B.
When the temperature has reached 130 to 150 degrees Centigrade, the heating
apparatus is removed and by means of the spiral gear c, the two vessels B and C are
brought into the position as shown in Fig. 2.
In this position the liquid Ammonia gas evaporates again and returns through
the canals a and d of the connecting tube D into the vessel B where it is again

page_text: absorbed by the solution weakened of Ammonia, and in consequence of the
expansion of the gas, the cold is produced in the freezing vessel C. A block of
transparent ice is than produced in the mouldse e placed in the freezing vessel (
In commencing a new operation the machine is brought into the position shown
in Fig. 3. so as to cause all the fluid which collected in the vessel C to return
through the canal a of the tube D into the vessel B, and by means of the canal d and

'HILIP BORN 11 Queen Victoria Street, London, in the County of Middlesex,
Manufacturers Agent, 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 as shown in the drawings left with the provisional specification,
consists of a cold water tank A a boiler B and a freezing vessel C, the two vessels B
and C are connected by means of a tube D, the interior of this tube D consists of two
seperate passages or canals a and d
The tube D is fixed to an axle E as shown in Fig. 4 which turns and rests in
bearings F and F as shown in Fig 4 and can be turned by means of the spiral
gearing c by which means the vessels B and C can be brought in any desired position
as shown in Fig. 1, 2, 3.
The manipulation to produce ice is as follows: fill the tank A with cold water,
place the vessels B and in the position shown in Fig. 1, fill the vessel B about full
with a full saturated solution of Ammonia, place under the vessel B a gas, petroleum,
charcoal or any other suitable heating apparatus and light the same. After the air
has escaped through the small opening at the top of the tube D as shown in
Fig. 1, close the opening f by means of a screw stopper, the Ammonia gas arising
out of the solution will now pass through the canal a of the tube D into the freezing
vessel C in which it condenses and becomes fluid.
To prevent parts of the fluid solution being drawn into the canal a, through its
boiling action, a metal guard b and several perforated plates or sieves 6' are fixed in
the cover of the vessel B. The opening 9 as shown in Fig. 4, permits the introduction
of a Thermometer into the vessel B.

page_text: When the temperature has reached 130 to 150 degrees Centigrade, the heating
apparatus is removed and by means of the spiral gear c the two vessels B and C are
brought into the position as shown in Fig. 2.
In this position the liquid Ammonia gas evaporates again and returns through the
canals a and d of the connecting tube D into the vessel B where it is again absorbed by
the solution weakened of Ammonia and in consequence of the expansion of the gas
the cold is produced in the freezing vessel C, a block of transparent ice is than
produced in the moulds e e placed in the freezing vessel C.
In commencing a new operation the apparatus is brought into the position shown
in Fig. 3 so as to cause all the fluid which collected in the vessel C to return through
the canal a of the tube D into the vessel B, and by means of the canal d and its
prolongation d¹ the air in the vessels B and C is balanced.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
The general arrangement of the ice producing apparatus in particular the tube D,
which connects the vessels B and C, and its interior consisting of the canals a and d
and the prolongation d' and bringing the vessels B and C into any required position
by means of the spiral gear c, the whole substantially as described and shown in the
drawings.
