Improvements in the Manufacture of Carbonated Waters.
MARK LOUIS OR, Soda Water Manufacturer of Palermo. Blackrock,
County Dublin PIERCE GILES HOVENDEN, Soda Water Manufacturer of Spencer
Villa Moyne Road, Dublin and JAMES VASS Soda Water Machinist of
131, St. Stephen's Green W. Dublin 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:-
The object of our invention is the more highly charging of waters with carbonic
acià gas and to obtain this we employ a closed tank or vessel capable of standing
pressure, to hold the liquid to be carbonated and we employ an ordinary carbonating
machine consisting of a pump and cylinder. To this cylinder we fix on the top an
automatic safety valve for allowing any excess of gas to escape, and as better
results are obtained by passing more gas through the pump than the liquid will
theoretically absorb, this gas is as a rule either returned to the producer or escapes
to waste, but according to our invention we conduct this excess gas to the subsidiary
tank or vessel and we provide an inlet pipe or perforated partition at or near the
bottom of same for entry of gas and to cause same to be divided up into smaller
bubbles and pass through the liquid. At the top of this closed vessel we provide
a safety valve to open at a lower pressure than in the carbonating cylinder. When
this is opened the air is allowed to escape, being displaced from the water by the
gas which has been passed through it. This vessel is also provided with a gauge
glass, so that when empty it can be refilled and at the bottom is connected to the
water suction of the soda water carbonating machine. To obviate the refilling of
the tank, when we have a suitable supply with sufficient pressure of liquid we
employ a floating ball operating on the inlet cock, but where this is not obtainable
we provide a pump which is thrown in and out of gear by the action of the float,
which is connected to suitable disengaging gear (when the pump is operated by
power).
As in the manufacture of carbonated mineral waters it is necessary to add to
the water certain salts in solution we also employ two pumps on one frame of
proportionate diameters to the amount required, one for the salts in solution and
the other for the water.
In operation the water in our closed tank gradually becomes thoroughly charged
with gas and any air originally in same has been driven out and escaped. When
the water is pumped out by the carbonating machine a further quantity of gas is
forced in in the usual way and waters are obtained of a highly charged nature at
a comparatively low pressure.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The employment of a vessel in connection with any carbonating machine to
hold the liquid to be carbonated and connected to the cylinder so that the surplus
gas shall partially charge same as herein described.
2. The employment of a secondary pump or pumps for filling this vessel in a
continuous manner as herein described.
