IMPROVEMENTS IN PREPARING OR MAKING UP MEDICATED AND OTher EFFERVESCING MIXTURES.
Year: 1872

page_text: LETTERS PATENT to William Temple Cooper, of Oxford Street, in the
County of Middlesex, Pharmaceutical Chemist, for the Invention
of "IMPROVEMENTS IN PREPARING OR MAKING UP MEDICATED AND OTher
EFFERVESCING MIXTURES.'
Sealed the 28th January 1873, and dated the 24th October 1872.
PROVISIONAL SPECIFICATION left by the said William Temple Cooper
at the Office of the Commissioners of Patents, with his Petition, on
the 24th October 1872.
I, WILLIAM TEMPLE COOPER, of Oxford Street, in the County of
Middlesex, Pharmaceutical Chemist, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN PREPARING OR MAKING UP MEDICATED
AND OTHER EFFERVESCING MIXTURES," to be as follows:-
My Invention consists in the preparation or making up of effervescing
mixtures in the form of lozenges, which are manufactured by the aid of
pressure in diés. These lozenges effervesce on being dissolved in the mouth,
and form an agreeable means of administering effervescing mixtures,
medicated for the treatment of ailments, and are especially valuable in
cases in which it would be hurtful to take the quantity of liquid required
for mixing an effervescing draught, as in the treatment of diabetes for

page_text: instance. The lozenges may also be made without medicinal properties
for use by public speakers and others for moistening the mouth or
alleviating thirst. As the materials must not be wetted they cannot be
made into a paste as in the ordinary method of making lozenges. I
therefore take the effervescent mixture or materials and mix it with a
little sugar, and if necessary gum or other glutinous substance, to give it
coherence, and then compress it in a dry state in suitable dies to form
lozenges, which may be flavoured or not.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Temple Cooper in the Great Seal Patent
Office on the 24th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
TEMPLE COOPER, of Oxford Street, in the County of Middlesex, Phar-
maceutical Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of October, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Temple Cooper, Her special
licence that I, the said William Temple Cooper, my executors,
administrators, and assigns, or such others as I, the said William
Temple Cooper, 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 Inven-.
tion for "IMPROVEMENTS IN PREPARING OR MAKING UP MEDICATED AND OTHER
EFFERVESCING MIXTURES," upon the condition (amongst others) that I,
the said William Temple Cooper, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands
and seals, 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.

page_text: NOW KNOW YE, that I, the said William Temple Cooper, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Sheet of
Drawings hereunto annexed and to the letters and figures marked thereon
thereon (that is to say) :-
My Invention consists in the preparation or making up of effervescing
mixtures in the form of lozenges, which are manufactured by the aid of
pressure in dies. These lozenges effervesce on being dissolved in the
mouth, and form an agreeable means of administering such mixtures,
medicated for the treatment of ailments, and are especially valuable in
cases in which it would be hurtful to take the quantity of liquid required
for mixing an effervescing draught, as in the treatment of diabetes for
instance. The lozenges may also be made without medicinal properties
for use by public speakers and others for moistening the mouth or
alleviating the thirst. As the materials must not be wetted they cannot
be made into a paste as in the ordinary method of making lozenges. I,
therefore, take the effervescible mixture, or the ingredients, for forming
the same, and mix therewith small quantities of sugar, in powder, in the
proportion of about three parts of sugar to two parts of the mixture. A
variable proportion of powdered gum may also be added, to give it
coherence, but this is usually unnecesary, and I prefer to omit it. The
mixture is then compressed in a dry state in suitable dies to form
lozenges, which may be flavoured or not, as desired. The ingredients I
use to form the effervescible mixture are the same as those put in
effervescing draughts by chemists, and consist usually of a carbonate of
an alkali, such as soda or potash, with an acid (citric or tartaric,
preferably the latter), or acid salt, both in a dry and powdered state.
Medicines or any flavoring matter which can be prepared in a dry state
and reduced to powder can be mixed with the indredients to impart the
desired medicinal qualities or flavor, as the case may be.
Dies of an ordinary description may be used, but the dies which I find
answer best, and which I employ, are shown in central vertical section
in the accompanying Drawing. These dies are preferably made in three
pieces to admit of the lozenge being readily withdrawn, and consist of
an upper die or plunger a, a mould 6, and a lower die c; the mould 6 is
open throughout, and is closed at bottom by the lower die when in use,

page_text: as shown. The faces of the two dies, which should be perfectly smooth
or polished, may be hollowed or otherwise formed to produce a lozenge
of any desired shape, that shown by the space left between the dies being
preferred, as the upper and lower dies should not come in contact. The
mould b being placed on the lower die is filled with the mixture, and the
upper die is placed thereon, and pressed slightly to cause it to enter the
mould sufficiently to guide it in its descent when placed beneath the
plunger of a fly press, by which the ingredients are compressed into a
solid form. The dies are then removed from the press, and the finished
lozenge removed from the mould, which is again filled, and the operation
repeated as before.
Having described the nature of my Invention, and the manner in
which the same is to be performed, I declare that what I claim as my
Invention to be protected by the herein-before in part recited Letters
Patent is, the manufacture of effervescible lozenges from a mixture of
ingredients in a dry state by the aid of pressure in dies, substantially as
set forth.
In witness whereof, I, the said William Temple Cooper have
hereunto set my hand and seal, this Twenty-third day of April,
in the year of our Lord One thousand eight hundred and seventy-
three.
