PROVISIONAL
SPECIFICATION.
Improvements in the Manufacture of Concentrated Preparations of
Tea and Coffee, and of Aërated Tea and Coffee.
We, JAMES ARTHUR PHILLIPS of 47 Minories, Druggist, and LEONARD
BUTLER WRIGHTSON of John Street, Minories, Tea Merchant, both in the County
of London, do hereby declare the nature of this invention to be as follows:-
:-
The object of our invention is to manufacture concentrated preparations of tea
and coffee, that shall contain all the natural aroma and be free from turbidity, and
that when bottled, will keep fresh clear and aromatic, available at any time
for immediate use, when diluted with hot or cold water. Another object of our
invention is to utilize the extracts in the manufacture of aërated drinks.
According to this invention, we percolate blended or other tea or coffee with
pure glycerine and cold or lukewarm distilled water, air being excluded. In this
manner we retain all the aroma. The tea or coffee should be in a comminuted
condition, and we are able to use tea dust to advantage. Flavouring substances
may be added if desired. The percolate or extract obtained should be bottled at
once. The tea or coffee extract, when diluted with hot or cold water forms a
pleasant beverage, to which sugar and cream or milk may be added according to
taste.
Or we may combine the tea or coffee extract with aërated water during the
manufacture or bottling of the latter, the extract if desired, mixed with flavouring
substances, being drawn in by the syrup pump or otherwise, and distilled water
being used.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Concentrated Preparations of
Tea and Coffee, and of Aërated Tea and Coffee.
We, JAMES ARTHUR PHILLIPS of 47, Minories, Druggist, and LEONARD
BUTLER WRIGHTSON of John Street, Minories, Tea Merchant, both in the
County of London, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of our invention is to manufacture concentrated preparations of tea
and coffee that shall contain all the natural aroma and be free from turbidity,
and, that when bottled will keep fresh, clean and aromatic, available at any
time for immediate use when diluted with hot or cold water or with aërated water.
Another object of our invention is to utilize the extracts in the manufacture of
aërated drinks.
According to this invention we percolate blended or other tea or coffee with
pure glycerine and cold or lukewarm distilled water, air being excluded. In this
manner we retain all the aroma. The tea or coffee should be in a comminuted
condition and we are able to use tea dust to advantage. Flavouring substances
may be added if desired.
A suitable mode of carrying out this part of our invention is as follows.
The tea or coffee carefully blended is packed in a glass percolator, 8 ounces
being a suitable quantity to treat. We then percolate with a mixture of glycerine

page_text: and distilled water, about 54 ounces of the former and 27 ounces of the latter,
the percolation being regulated so as to extract the full strength from the tea
or coffee. In hot weather in order to assist the keeping properties we add
about 1 ounce of boracic acid to the tea or coffee before percolation. The
percolate or extract obtained should be bottled at once.
The above tea or coffee extract when diluted with hot or cold water or with
aërated water such as salutaris water, forms a pleasant beverage to which sugar
and cream or milk may be added according to taste.
Or we may combine the tea or coffee extract with aërated water during the
manufacture or bottling of the latter, the extract if desired mixed with
flavouring substances, being drawn in by the syrup pump or otherwise and
distilled water being used in the proportion of about 1 part of the extract
to 14 parts of the water.
The extracts or aërated drinks made as described will not decompose or
produce fungoid growth.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The manufacture of tea and coffee extracts by percolating them with
glycerine and distilled water substantially as set forth."
2. The manufacture of aërated beverages substantially as set forth.
