An Improved Method and Apparatus for Preparing Beverages
Containing Carbonic Acid.
I, MAX HOLZAPFEL of the City and county of Newcastle on Tyne, Manufacturer
do hereby declare the nature of this invention to be as follows :-
The beverages are impregnated with carbonic acid under pressure in the following
manner: use a cylinder vessel or holder, at least 3 feet long at one end of which a
perforated aperture is inserted, through which the liquid, which is to be impregnated
with carbonic acid, enters in finely divided particles. The cylinder is nearly filled
with small pieces of a porous substance, such as pumice stone, coke ect., or with
many small pieces of another substance which is not soluble in the liquid or in
carbonic acid, as for instance glass, marble, china ect. The carbonic acid is introduced
as near to the bottom as convenient, so that the acid penetrates the cylinder from the
bottom towards the top, the liquid from the top towards the bottom. The liquid which
has entered through the perforated opening is further subdivided by the small pieces
contained in the Cylinder. The carbonic acid, entering from the opposite direction,
comes into contact with very small particles of the liquid at very many points.
I find it convenient to introduce the carbonic acid under a pressure of sixty to seventy
five pounds per square inch. The liquid is introduced at such a ratio, that the pieces
of coke in the cylinder just remain saturated. Under these conditions the liquid
absorbs the largest possible quantity of carbonic acid. It can then be withdrawn
through a cask at the bottom of the cylinder.
By these means a liquid containing the maximal quantity of carbonic acid, is
obtained so long as the necessary quantities of carbonic acid and liquid are simul-
taneously introduced. In fact the process enables me to produce uninterruptedly
beverages containing carbonic acid by the means of a cylinder or vessel containing
small pieces of a suitable substance, by which the largest possible surface of the liquid
to be impregnated is exposed to the carbonic acid which enters from the opposite
side and simultaneously comes into contact at a great many points.

An Improved Method and Apparatus for Preparing Beverages
Containing Carbonic Acid.
I MAX HOLZAPFEL of the City and County of Newcastle on Tyne, Manufacturer
do hereby declare the nature of this invention and in what manner the same is to
be performed, to he particularly described and ascertained in and by the following
statement :-
The beverages are impregnated with carbonic acid under pressure in the following
manner I use a Cylinder, vessel or holder at least 3 fee tlong at one end of which a
perforated aperture is inserted through which the liquid to be impregnated with
carbonic acid, enters in finely divided particles. The Cylinder is nearly filled with
small pieces of glass, porcelain pumice stone or coke or such other suitable substance
as may not be soluble in water or Carbonic acid; the Carbonic acid is introduced as
near to the bottom as convenient B so that the acid penetrates the cylinder from
the bottom to the top, the liquid from the top towards the bottom. The liquid which
has entered through the perforated opening is further subdivided by the small pieces

thus comes in contact with very small particles of the liquid at very many points
After being thus impregnated, the liquid by its own weight falls to the bottom and
enters an accumulator whence it is drawn off into bottles by suitable arrangements.
D is the pump and E is a pipe by which the water is drawn into the pump.
It then enters the Cylinder at F. G is a valve to let the air out of the Cylinder.
Having now particularly described the nature of my said invention and in
what manner the said is to be performed I declare what I claim as novel & as
my invention is:
The arrangement for subdividing the surface of the water by small pieces of glass
or other suitable substances by which the impregnation of the largest quantity
possible, of Carbonic acid gas is brought about, and the accumulators at the back of
the machine, by which a constant supply of impregnated water is maintained.
Dated this 21st day of December 1889.
