WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent
Agents, Southampton Buildings, London, "IMPROVEMENTS IN THE MANUFACTURE
OF COMPOUNDS FOR MAKING EFFERVESCENT LIQUIDS" [a communication to him
from abroad by Gebr. Stollwerck of Cologne-on-the-Rhine, in the Empire of
Germany]
This invention relates to the manufacture of compounds for causing liquids to
effervesce and the object of the said invention is to prepare such compounds so
that the substances or ingredients which they contain for producing the carbonic
acid when combined with water, are kept separate from each other, instead of
being mixed as heretofore.
The said invention consists essentially in thoroughly mixed bicarbonate of soda
with pulverized sugar. The latter before being mixed with the said bicarbonate
of soda, is preferably flavored by adding to it some suitable volatile oil or perfume
so as to give it a flavor of raspberry, apple, ginger, pine-apple or other fruit, or the
said sugar may also be mixed with some medicine or drug in a pulverized state,
such as Chininum sulphuricum, Ferrum oxidatum dialysatum, Santoninum, or the
like. Part of the said mixture of sugar and bicarbonate of soda is then brought
into a mould or die, preferably of a square shape and of convenient size, and is
pressed down therein by means of a suitable stamper or pestle. Then by means of
some proper instrument a cavity is made in the centre of the said mass and into
the said cavity a proper amount of pulverized citric acid or tartaric acid is
introduced which is then also pressed down therein, whereupon another part of the

page_text: said compound of sugar and bicarbonate of soda is placed on the top of the acid
and pressed down thereon so that the said acid forms the core of the surrounding
compound of sugar and bicarbonate of soda. The entire mass after having thus
been thoroughly pressed down is allowed to remain in the said mould for some
time, and is then taken out. If the mould is of a square shape, the mass will be of
a square shape likewise that is to say the lumps of effervescent material thus
obtained will be of the shape of a hexahedron containing the carbonate and the
acid separated from each other; this arrangement provides against a premature
reaction in case of moisture whereby the said effervescent compound may be kept
without spoiling
It is obvious that instead of mixing the carbonate with the sugar, the latter may
-be-mixed-with-the-acid-and-the-carbonate-be-introduced-into-the-cavity provided
in the centre of the mixed mass after the same has been pressed down as above
described. In this latter instance the carbonate would form the core of the
surrounding compound of sugar and acid
In using the lumps of effervescent compound thus obtained, the same are crushed
in some suitable vessel, whereupon water or other suitable liquid is added which
will cause the mixture to effervesce.

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co Patent
Agents, Southampton Buildings, London. IMPROVEMENTS IN THE MANUFACTURE
OF COMPOUNDS FOR MAKING EFFERVESCENT LIQUIDS."-A communication to me
from abroad by Gebr. Stollwerck, of Cologne-on-the-Rhine, in the Empire of
Germany
This invention relates to the manufacture of compounds for causing liquids to
effervesce; and the object of the said invention is to prepare such compounds so
that the substances or ingredients which they contain for producing the carbonic
acid when combined with water, are kept separate from each other, instead of
being mixed, as heretofore.
The said invention consists essentially in the novel method of combining the
substances of which the compound is composed, for the purpose of providing
against premature re-action, and causing the compound to keep without spoiling,
as hereinafter specified.
The said compound consists principally of pulverized sugar, bi-carbonate of soda
and citric or tartaric acid.
The sugar which is preferably flavoured by adding to it some suitable volatile
oil or perfume, so as to give it a flavour of raspberry, apple, ginger, pine-apple, or
other fruit, but which may be mixed with some medicine or drug in a pulverized
state, such as Chininum sulphuricum, Ferrum oxidatum dialysatum, Santoninum,
or the like, is first mixed with the bi-carbonate of soda. A portion of the said
mixture of sugar and bicarbonate of soda is now placed in a mould or die, and is
pressed into a lump therein by means of a suitable stamper or pestle. By means
of a convenient instrument a cavity is formed in the centre of the said lump, and
into this cavity a proper amount of pulverized citric or tartaric acid is introduced
and pressed down, and a further portion of the said compound of sugar and
bicarbonate of soda is placed on the top of the said acid so that the latter forms
the core of the surrounding compound of sugar and bicarbonate of soda. The
entire lump after having been thoroughly compressed, is allowed to remain in the
mould for some time.
If the mould is of a square shape, the said lump will also be of a square shape,
that is to say, the lump of effervescent compound thus obtained will be of the shape
of a hexahedron, containing the carbonate and the acid separated from each other.
This arrangement provides against a premature re-action in case of moisture, and
enables the said effervescent compound to be kept without deteriorating.
It is obvious that instead of mixing the carbonate with the sugar, the latter may
be mixed with the acid, and the carbonate be introduced into a cavity formed in
the centre of the mass after the latter has been compressed as above described.
In this instance the carbonate would form the core of the surrounding compound
of sugar and acid.
It is also obvious that instead of one cavity a number of cavities may be formed
and filled with one of the ingredients of the compound, and also that the separation
of the carbonate from the acid may be effected by arranging the carbonate, sugar
and acid in layers, the one on the top of the other, without departing from the
nature of this invention,
In using lumps of effervescent compound thus obtained, the same are crushed in
some suitable vessel and water or other suitable liquid is added, whereupon the
said liquid is caused to effervesce and produce a refreshing drink similar to
sparkling lemonade.

page_text: The before-mentioned ingredients applied for preparing the said effervescent
compound as herein described, are preferably made use of in about the following
proportions that is to say flavored or non-flavored, drugged or non-drugged sugar,
five (5) parts by weight more or less; bicarbonate of soda, one (1) part by weight
more or less; and citric acid or tartaric acid one (1) part by weight more or less.
The mould or die wherein the said effervescent compound is made into lumps
may be of any convenient form and construction. It is however preferably square.
The mould must in all cases conform to the shape of the pestle or stamper applied
for stamping down the said sugar carbonate and acid.
}
[
The said lumps of effervescent compound are preferably made of such size as to
measure about three fourths to one inch in every direction..
Having-thus-fully-described-the-said-invention-as-communicated-to-me-by-my-
Foreign.correspondent and the manner of performing the same I wish it understood
'that I Claim
First. The herein described lump of compound for causing liquids to effervesce,
and which consists of pulverized sugar suitably flavored and readily soluble in
water, the said pulverized sugar being mixed with citric or tartaric acid and
enclosing carbonate of soda, or vice versa, being mixed with the carbonate and
enclosing the acid, substantially as, and for the purpose, set forth
Second. The herein described lump adapted to be used for medicinal purposes,
and which consists of pulverized sugar suitably drugged and readily soluble in
water, the said drugged sugar being mixed with, the carbonate and surrounding
the acid, or vice versa, substantially as, and for the purpose set forth
Third. In the manufacture of-compounds for causing liquids to effervesce, the
process, substantially as set forth, which consists in flavoring or drugging pulverized
sugar, then mixing the same with bicarbonate of soda, and introducing into the
said mixture a core of citric or tartaric acid for the purpose specified.
Fourth. In the manufacture of compounds for causing liquids to effervesce, the
process, substantially as hercin set forth, which consists in flavoring or drugging
pulverized sugar, then mixing the same with citric or tartaric acid and introducing
into the said inixture a core of bicarbonate of soda, for the purpose specified.
In Witness whereof I the said William Robert Lake have bereunto set my hand
and seal this Sixth day of October in the year of Our Lord one thousand, eight
hundred and eighty three.
