I, JAMES FORBES HENDERSON, of Aberdeen, Aberdeenshire, North Britain, Manu-
facturer, do hereby declare the nature of the said Invention, to be as follows:-
This Invention relates to the production of homogeneous soluble compounds or
admixtures of "saccharine" with coffee and coffee extracts, essences and compounds
hereinafter referred to as coffee.
The Invention consists essentially in the production of such compounds or admixtures
by the application and use in combination with soluble saccharine and coffee, of
glycerine, which is compounded and intimately mixed in suitable proportions with
suitable relative proportions of such respective ingredients.
Soluble saccharine is a powdered product consisting essentially of bicarbonate of
soda and saccharine, and in such condition a homogeneous admixture thereof with
coffee as ordinarily prepared cannot be produced, the tendency of the finely powdered
soluble saccharine being to settle downwards in the mass of coffee so that in a very short
time the compound is lacking in homogeneity, the upper portion being insufficiently
sweetened and the lower portion too intensely sweetened.
The special object of the present Invention is to cause the mutual adherence of such
ingredients and to produce homogeneous soluble compounds thereof in which the
soluble saccharine is distributed equably and maintained in equable distribution
throughout the mass and such object I attain in accordance with the present
improvements by admixing suitable proportions of glycerine with suitable relative
proportions of the other said respective ingredients, intimately and thoroughly
admixing such combined ingredients so as to produce a homogeneous mixture thereof.
The glycerine is further of advantage in preserving the aroma of the coffee and its
contained essential principles, and renders the product more easily soluble.
Such improved compounds are preferably hermetically closed in tins, bottles or other
suitable receptacles for sale or until required for use.
Dated this 25th day of October 1887.

page_text: I, JAMES FORBES HENDERSON, of Aberdeen, Aberdeenshire, North Britain, Manu-
facturer, do hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This Invention relates to the production of homogeneous soluble compounds or
admixtures of "soluble saccharine" with coffee, and coffee extracts, essences and
compounds hereinafter intended to be comprehended where the word "coffee" alone
occurs.
Soluble saccharine is a finely powdered product which when mixed with coffee as
ordinarily prepared tends to settle downwards in the mass thereof so that in a short
time the compound is lacking in homogeneity, the upper portion being insufficiently
sweetened and the lower portion too intensely sweetened.
The special object of the present Invention is to cause the mutual adherence of such
ingredients and to produce homogeneous soluble compounds thereof in which the
soluble saccharine is distributed equably and maintained in equable distribution
throughout the mass of coffee, and to this end the Invention consists essentially in the
application and use for such purpose of glycerine, the said ingredients being intimately
adimixed in suitable relative proportions so as to produce a perfectly homogeneous
mixture thereof.
Without limiting myself to the following proportions of the said respective
ingredients or the following methods of compounding the same I give the following as
those which I have found to give the desired result.
To every 112 lbs. of ground roasted Coffee Beans, take about 9 ounces of soluble
Saccharine, about 20 Huid ounces of pure Glycerine and about, 18, ounces of
Bicarbonate of Soda.
For the production of saccharinated coffee, the coffee when ground is caused to fall
into an enclosed coffee mixer, a portion (say about 14 lbs. thereof) being kept back
and put into a large mortar which has been previously warmed, to this portion the
glycerine is added and intimately mixed therewith by means of a suitable pestle or in
any other suitable manner. The soluble saccharine is then added to such mixture and
is intimately mixed therewith in any suitable manner, after which the Bicarbonate of
Soda is added to the mixture, the whole of the ingredients being then pounded or
otherwise suitably intermixed in any suitable manner, after which the mixture is
added to the bulk of the coffee in the mixer, and the whole is kept in motion until a
perfectly homogeneous mass is obtained. The coffee is then put up in tins or other
suitable receptacles which are hermetically sealed.
The Glycerine besides serving the purpose of enabling a homogeneous mass to be
obtained, is also of advantage in retaining the Cafeine, aroma and essential principles
of the coffee and in rendering the product more easily soluble. The Bicarbonate of
soda is also of advantage in giving a richer infusion.of.Coffee and by neutralising the

page_text: Cafeic Acid renders the Coffee more easily digestible. The soluble saccharine is of
advantage in imparting sweetness to and in making the coffee palatable, being used in
lieu of sugar, and coffee prepared therewith as herein described can be freely taken by
persons of weak or impaired digestion, and in all cases where sugar is contra
indicated.
In some other preparations of coffee, a less proportionate quantity of glycerine may
be used, say about one quarter of that hereinbefore mentioned, for example, in the
production of saccharinated coffee essence, the whole of the said quantity of coffee is
placed in a steam jacketted tinned copper percolator and about 65 gallons of boiling
distilled water in which the said bicarbonate of soda has been dissolved is allowed to
percolate slowly through the coffee, care being taken that the coffee is kept covered
till the last of the water is added and that the mass is kept at boiling point by steam
or otherwise during the process which should take about an hour. The infusion from
the percolator (about 60 gallons) is discharged into a vacuum pan of suitable capacity
wherein it is mixed first with the glycerine and then with the soluble saccharine, the
mixture is afterwards evaporated to about one third its bulk and is immediately after-
wards bottled in the ordinary way. This gives a very superior essence of coffee
requiring no sugar, and containing all the stimulating and nutritive properties of coffee
in a concentrated form.
In the preparation of saccharinated Coffee Tablets, an infusion is made as
immediately above described, and with which the glycerine is mixed, after which the
soluble saccharine, together with about 41 lbs. of pure raw Cane sugar is dissolved
therein prior to the evaporation of the infusion, which should be continued till the
mass is of a proper consistency for cutting up into tablets of any suitable size, and
which are packed in hermetically sealed tins or other suitable receptacles wherein they
will keep indefinitely, and when required for use can be dissolved in hot water.
For troops on service, exploring expeditions and travellers, Saccharinated Coffee
tablets will be of considerable service.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The production of homogeneous soluble compounds of soluble saccharine with
coffee by the application and use in combination with such ingredients of glycerine,
the whole of such ingredients being intimately admixed in suitable respective pro-
portions.
2. The hereinbefore described improved compounds of coffee.
