IMPROVED PREPARATIONS OF TEA, Coffee, Cocoa, AND MILK
Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
SEARLE, of Batlı, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of June, in the fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Charles
Searle, Her especial licence, full power, sole privilege, and authority, that I,
the said Charles Searle, my cxors, adñiors, and assigns, or such others, as
I, the said Charles Searle, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVED PREPARATIONS OF TEA, Coffee, Cocoa, AND MILK;'
in which said Letters Patent is contained a proviso, that I, the said Charles
Searle, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Searle, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof (that is to say) :-
The Invention relates to preparing and solidifying milk after the cream is
removed by evaporating the aqueous matter therefrom, and also to combining

page_text: tea, coffee, and cocoa, with milk so prepared. And in order that the In-
vention may be fully understood, and readily carried into effect, I will proceed
to describe the process pursued by me, first remarking that I am aware that
it has been before proposed to prepare milk, together with the cream, by
solidifying by evaporation, and also afterwards combining the same with tea,
coffee, and cocoa; but it has been found that the presence of cream renders the
product obtained readily acted on and easily injured and spoiled by climate
and atmosphere, becoming rancid and offensive; but by first removing the
cream, the product obtained will keep sweet a very much longer time. Having
removed the cream from the milk to be prepared, I put the milk into a suitable
vessel surrounded by or contained in a water bath, adding thereto not less than
one-fortieth part of loaf sugar, by weight, with the view of increasing the
solubility of the product, and as tending to its preservation; and by means of
steam or other heat applied to the bath or surrounding water-containing vessel,
I evaporate the aqueous matter therefrom, taking care that the temperature of
the beat applied does not injure the milk; and the most advantageous mode of
evaporating the aqueous matter from the milk, is by means of a closed vessel;
into which the milk is put, and from which the air and vapours are withdrawn,
and a partial vacuum is obtained, by which the evaporation will be performed
at a low temperature, in like manner to the means now commonly resorted to
in refining sugar, and which is well understood. by engineers; and in this
manner a product of milk may be obtained in a pure and perfectly dry state,
which may be preserved in closely-stopped bottles or jars. And when the
milk is to be combined with tea, coffee, or cocoa, a strong extract of either of
such matters is to be previously obtained by a carefully-conducted evaporation
of a concentrated aqueous infusion in vacuo, or by distillation, and the fluid
extract, thus obtained, added to the milk at an advanced stage of its pre-
paration towards solidification, mixing therewith a suitable proportion of refined
sugar, or not, as it may be desired, and continuing the evaporation of the
compound at a low and carefully-conducted temperature in a glass, porcelain,
silver, or other suitable vessel, immersed in a water bath, till the whole is con-
verted into syrup, paste, candy, or powder; or by the addition of arrowroot,
isinglass, Iceland moss, or the like, and thus rendered more nutritive, con-
verted into lozenges, adding these, one or other, or not, or some essence or
spice, to impart flavor, as may be desired.
In witness whereof, I, the said Charles Searle, have hereunto set my
hand and seal, this Third day of December, in the year of our Lord
One thousand eight hundred and forty-two.
CHARLES (L.B.) SEARLE.
