in the County of Glamorgan, for an Invention of "IMPROVEMENTS IN AND
RELATING TO THE MANUFACTURE OF FOOD OR MATERIAL FOR FORMING
PROVISIONAL SPECIFICATION left by the said Edward Williams and John
Williams at the Office of the Commissioners of Patents on the 25th February
1881.
EDWARD WILLIAMS and JOHN WILLIAMS, both of Swansea, in the County of
Glamorgan. "IMPROVEMENTS IN AND RELATING TO THE MANUFACTURE OF FOOD
OR MATERIAL, FOR FORMING DECOCTIONS OR DRINKS RESEMBLING (AND FORMED
IN PART OF) COFFEE."
This Invention relates to the manufacture of a material possessing all the
advantageous properties of dandelion and of coffee combined, and consists in
saturating and soaking coffee with extract of dandelion, preferably during the
roasting process, as hereafter described.
The following description of the manufacture of some of our product is given
as an illustration of the process, and not as binding us to these exact ingredients
and quantities, as they can be considerably varied to suit taste and other
circumstances:-
Take 33 pounds weight of dandelion root as prepared and roasted, duty paid, same
as coffee, then place this quantity in water and boil it till all the soluble matter has
been extracted. Strain or filter it, and boil down the liquor till it weighs only 2
pounds. Add ½ pound of lump sugar. It is now a syrup. Take 112 pounds of
raw coffee; roast it. When it has gone through the half roasting process, commence
adding the syrup. The warm coffee quickly absorbs it, especially towards the
finish of the roasting; without the syrup the coffee would roast down from 112 to
96 pounds, with the syrup to 98, showing that but a small proportion of the syrup
is lost by evaporation.
The result is a coffee that contains the full medicinal properties of the dandelion
plant in combination with the coffee, and in a very concentrated form.
As soon as this prepared coffee is cold after roasting, it is ground (mixed if desired
with chickory and burnt sugar) and placed in air tight cases. It is now ready for
The refuse dandelion after boiling is thrown away.
use.
It will be seen from the above that it takes 112 pounds of coffee and 33 of
dandelion, or 145 pounds on which duty has been paid to make 98 parts of the
prepared coffee.

EDWARD WILLIAMS and JOHN WILLIAMS, both of Swansea, in the County of
Glamorgan. "IMPROVEMENTS IN AND RELATING TO THE MANUFACTURE OF FOOD
OR MATERIAL FOR FORMING DECOCTIONS OR DRINKS RESEMBLING (AND FORMED
IN PART OF) COFFEE."
This Invention relates to the manufacture of a material possessing all the advan-
tageous properties of dandelion and of coffee combined, and consists in saturating
and soaking coffee with extract of dandelion, preferably during the roasting process
as hereafter described.
The following description of the manufacture of some of our product is given
as an illustration of the process, and not as binding us to these exact ingredients
and quantities, as they can be considerably varied to suit taste and other
circumstances:-
Take thirty three pounds by weight of the dandelion root as imported, and on
which duty has been paid, prepare and roast it in the same manner as coffee, and
then place this quantity in water and boil it till all the soluble matter has been
extracted; next strain or filter the solution and boil down the resulting liquor until
it weighs only two pounds, and by the addition of a quarter of a pound of lump
sugar make it into a syrup. Take one hundred and twelve pounds of green
coffee, roast it, and when it has gone through half of the roasting process, commence
to add the syrup. The warm coffee quickly absorbs it, especially towards the
finish of the roasting. Without the addition of the syrup the one hundred and
twelve pounds of coffee would produce after roasting ninety six pounds, with the
syrup it produces ninety eight pounds, showing that but a small proportion of the
syrup is lost by evaporation.
The resulting product is a substance that contains in combination with coffee
the full medicinal properties of the dandelion plant, and in a very concentrated
form.
As soon as this prepared coffee is cold after roasting it is ground (mixed if
desired with chickory and burnt sugar) and placed in air tight cases.
It is now
ready for use. The refuse dandelion after boiling is thrown away.
It will be seen from the above that it takes one hundred and twelve pounds
of coffee and thirty three of dandelion, or one hundred and forty five pounds on
which duty has been paid to make ninety eight pounds of the prepared coffee.
Having now described our Invention, and the best mode known to us' of
carrying it into effect, we wish it to be understood that what we believe to
be new and desire to protect under the herein before in part recited Letters
Patent is,―
First. The manufacture of food or material for forming decoctions or drinks
resembling coffee, by treating the coffee, preferably during roasting, with a syrup
or extract, so as to cause it to absorb the extract or syrup into its pores, and thus
be capable of giving out a stronger decoction with a given weight of solid, and a
concoction combining the qualities of coffee and the syrup or extract employed.
Second. The manufacture of an extract or solution of dandelion, substantially as
and for the purposes described.
Third. As a new article of manufacture, coffee beans, or crushed or ground coffee

page_text: saturated or partially saturated with the soluble constituents of roasted dandelion,
preferably mixed with sugar, syrup, or other suitable glutenous material.
In witness whereof, we, the said Edward Williams and John Williams, have
hereunto set our hands and seals, this Twenty second day of August, in the
year of our Lord One thousand eight hundred and eighty one.
