PROVISIONAL SPECIFICATION.
Improved Process or Means or Arrangements for the Manufacture
of Carbonic Acid Gas.
I DAN RYLANDS of Shepcote Stairfoot near Barnsley in the Comity of York
Glass Bottle Manufacturer lo hereby declare the nature of this invention to be as
follows:-
My invention has for its object the production or manufacture of carbonic acid
gas in a very simple and economical manner. According to my invention I take
bicarbonate of soda or other suitable substance and instead of pouring thereon
sulphuric acid as is now done 1 place this bicarbonate of soda in a suitably shaped
vessel made of glass or any other suitable material or metal and I subject such
bicarbonate of soda to such a heat as will drive off the carbonic acid gas. The
said vessel containing the bicarbonate of soda connect either direct to a gas
holder for receiving the carbonic acid gas or to a pump for drawing off such
carbonic acid gas and forcing it under pressure into suitably closed inbes where it
can be held securely until it is required for transport or for use. In some cases the
pump is used for charging or aerating (with the carbonic acid gas) water in a
Suitable cylinder from whence it can be bottled off by the means in general use
amongst mineral water manufacturers. The resultant bye product will be carbonate
of soda which can be sold as such whereas under the system now in use the resultant
byeproduct is of little or no value. In addition to or in place of bicarbonate of
da any other suitable substance or bicarbonate may be used the special intention
of my invention being to substitute heat instead of sulphuric acid for obtaining
carbonic acid gas from any suitable substance or chemical compound especially after
such chemical compound has passed clear of the works where it has been made.

COMPLETE SPECIFICATION.
Improved Process or Means or Arrangements for the Manufacture
of Carbonic Acid Gas.
I, DAN RYLANDS of Shepcote, Stairfoot, near Barnsley, in the County of York,
Glass Bottle Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention has for its object the production or manufacture of carbonic acid
gas in a very simple and economical manner. According to my invention I take
Bicarbonate of soda or other suitable substance, and instead of pouring thereon
sulphuric acid as is now done I place this bicarbonate of soda in a suitably shaped
vessel made of glass or any other suitable material or metal, and I subject such
bicarbonate of soda to such a heat as will drive off the carbonic acid gas. The
said vessel containing the bicarbonate of soda I connect either direct to a gas
holder for receiving the carbonic acid gas or to a pump for drawing off such
carbonic acid gas and forcing it under pressure into suitably closed tubes where it
can be held securely until it is required for transport or for use. In some cases the
pump is used for charging or aerating (with the carbonic acid gas) water in a
suitable cylinder, from whence it can be bottled off by the means in general use
amongst mineral water manufacturers. The resultant bye-product will be carbonate
of soda which can be sold as such, whereas under the system now in use the

bicarbonate of soda any other suitable substance or bicarbonate may be used, the
special intention of my invention being to substitute heat instead of sulphuric acid
for obtaining carbonic acid gas from any suitable substance or chemical compound
especially after such chemical compound has passed clear of the works where it has
been made.
In the accompanying drawing a represents a bench of horizontal retorts furnished
with the usual ascension pipes b, hydraulic main c, mouth pieces and lids; d a gas
main conveying the carbonic acid gas to the holder e, a branch pipe f from the
main enables the gas-compressing pump to draw its gas supply either direct
from the retorts or from the holder or from both at the same time. The object of
this arrangement of gas pipes is to enable the compressing pumps at times to
produce a partial vacuum in the interior of the retorts (which is done by closing the
stop cock ), and so help in the giving off of the carbonic acid gas.
The liquefied gas after leaving the compressor is conveyed by pipe i to the iron
bottle, or a portion may be conveyed by branch pipe to the gas holder from
whence it can be bottled off by the means in general use amongst mineral water
manufacturers.
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 manufacture of carbonic acid gas from bicarbonate of soda or any other
suitable substance by means of heat applied as in manner herein set forth and
illustrated or any mere modification thereof.
