other when gas is required to be evolved; and the connection of the
vessels is made in such manner as to obtain self-regulation by the gas
acting on a piston surface or column of fluid, so as to prevent the
coming together of the separated materials, used for evolving the gas so

TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
SAMUEL TAYLOR, of 53, King Street, Manchester, Barrister-at-Law,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of August, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Samuel Taylor, Her special licence
that I, the said Samuel Taylor, my executors, administrators, and
assigns, or such others as I, the said Samuel Taylor, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN APPARATUS FOR GENERATING AND APPLYING CARBONIC ACID GAS,"
upon the condition (amongst others) that I, the said Samuel Taylor, by
an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Taylor, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
This Invention has for its object the combining apparatus in such
manner that carbonic acid gas may be generated and supplied to
vessels, in which are placed fermented or other liquids which it is desired

page_text: to preserve, by filling up the space from which a fermented liquid is
withdrawn, or which it is desired to ærate or press on for the purpose of
facilitating the drawing off from the vessel; and the Invention consists
of arranging the parts of the apparatus in such manner that the pres-
sure of the gas as it is evolved shall cause the mixing of the matters
used for evolving the gas to be regulated and to be stopped when the
gas evolved is sufficient for the time being; for which purpose separate
vessels are employed to contain the materials for evolving carbonic acid
gas, and the vessels are connected together so that the liquid used
(diluted acid) shall be allowed to flow from one into the other when gas
is required to be evolved, and the connection of the vessels is made in.
such manner as to obtain self-regulation by the gas acting on a piston
surface or column of fluid, so as to prevent the coming together of the
separated materials used for evolving the gas so long as the previously
evolved gas is sufficient.
Having thus stated the nature of my said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing shows a vertical section of an apparatus constructed
according to my Invention. The materials I prefer to use are marble
and dilute muriatic acid. The apparatus shewn is of glass, but other
suitable materials may be employed. Lumps of marble are placed in
the compartment A, of the apparatus, and the hollow plug (which is
ground into its seat and fits fluid-tight) is put into it splace; dilute acid
is poured into the compartment B, of the apparatus, and the cover c, is
fastened down. The plug h, forms part of a vessel, to the neck of
which the flexible tube f, is attached, by which the carbonic acid gas
is conveyed to the place where it is to be used; g, is a stop cock on
the pipe; c, is a collar or step formed on the vessel h', and on which a
washer of vulcanized india-rubber is placed; hence, when the cover c,
is fixed down, the vessel h, h', will be pressed downwards, and the
plug h, at its lower part will be pressed into its seat or opening. The

page_text: upper part of the plug h, ascends into the vessel h', as is shown, and
there is a neck formed at b, through which the dilute acid runs, and
descends to the marble below, except when the pressure of gas is such
as to act on the yielding surface of the dilute acid in the vessel h', so as
to force it back into the compartment B, of the apparatus. u, is a
very small hole in the vessel ', through which the dilute acid flows,
when permitted, from the compartment B, into the vessel ', and hence
down the plug h, at the bottom of the vessel ', amongst the marble in
the compartment A, of the apparatus. I would state that in place of
the gas acting on the yielding surface of the diluted acid, and thus pre-
venting the same flowing to such a height in the vessel h', as to allow
of its flowing over the upper part of the plug, and thence to the marble,
the apparatus may be so arranged that gas inay be caused to act on a
piston, so as to cause a plug to be closed, when the flow of diluted acid
is to be stopped, as will readily be understood by a mechanic; but I
think it better to act directly on the yielding surface of the dilute
acid. It will be evident that by the arrangement of apparatus shewn
that carbonic acid gas will be evolved from the marble so long as
the pressure of the gas in the vessel h¹, is insufficient to keep back
the dilute acid, hence the apparatus is self-regulating. The flow of
dilute acid will be stayed when the gas has for a time been evolved
faster than it has been allowed to escape by the pipef, but so soon as
the pressure again diminishes the flow of acid to the marble will
again take place, till the evolution of carbonic acid gas is again in
excess of the requirement, when the increased pressure will again, by
acting on the yielding surface of the dilute acid in the vessel h', press
it back and prevent its overflow for a time.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood I do not confine
myself to the form and arrangement of the parts shawn, as they may
be varied without departing from the peculiarity of the Invention,
which consists in so arranging or combining apparatus that the pressure
of the carbonic acid gas for the time being in the apparatus regulates
the further evolution of that gas by admitting, retarding, or preventing

page_text: the combining of the acid with the matters from which the gas is
evolved.
In witness whereof, I, the said Samuel Taylor, have hereunto set
hand and seal, this Twenty-second day of February, in the
year of our Lord One thousand eight hundred and fifty-four.
