the County of Surrey, for an Invention of "A NEW PREPARATION TO BE
USED AS A SUBSTITUTE FOR COFFEE."
PROVISIONAL SPECIFICATION left by the said Samuel Trevor Francis at
the Office of the Commissioners of Patents on the 25th February 1881.
SAMUEL TREVOR FRANCIS, of 118, Southwark Street, in the County of Surrey.
"A NEW PREPARATION TO BE USED AS A SUBSTITUTE FOR COFFee.”
This Invention has for its object to provide a new preparation to be used as a
substitute for coffee.
For this purpose I reduce grapes or raisins to a pulp by any suitable grinding
or pulping apparatus, and add sufficient meal or flour to such pulp to bring it to.
a stiff dough or paste, say, in the proportion of about 1/, of meal or flour. I then
reduce this stiff dough or paste to a thin cake, say, about 1/3 of an inch in thickness
and dry it. The dried cake I subsequently reduce into pieces of about the size of
coffee berries, and roast these pieces in the same way that coffee berries are now
roasted. The preparation so formed is afterwards ground to powder to be used as
a substitute for coffee.

"A NEW PREPARATION TO BE USED AS A SUBSTITUTE FOR COFFEE."
This Invention has for its object to provide a new preparation to be used as a
substitute for coffee.
For this purpose I reduce grapes or raisins to a pulp by any suitable grinding
or pulping apparatus, and add sufficient meal or flour to such pulp to bring it to
a stiff dough or paste, say, in the proportion of about 1/, of meal or flour. I then
reduce this stiff dough or paste to a thin cake, say, about '/; of an inch in thickness
and dry it. The dried cake I subsequently reduce into pieces, and roast these
pieces in the same way that coffee berries are now roasted. The preparation so
formed is afterwards ground to powder to be used as a substitute for coffee.
In practically carrying out my Invention I prefer to employ for reducing the
raisins to a pulp or stiff dough together with meal or flour of wheat, maize, or
other farina a kneading and mixing machine, such as is described in the Specifi-
cation of a Patent granted to P. Pfleiderer, No. 4116, in the year 1875; but other
constructions of kneading and mixing machines may be used for the purpose.
I first put into the machine the grapes or raisins and to some extent pulp them,
and then introduce the requisite quantity of meal or flour and knead the materials
together in the machine until the whole is reduced to the state of stiff dough.
This dough I subsequently reduce to a thin cake, say about '/, of an inch in
thickness, preferably by passing it between rollers. And I place the cakes on to
shelves in a drying chamber through which a current of heated air is passed so as
to dry the cakes. The dried cakes I subsequently reduce into lumps; the size
of the lumps is not very material; they may be as small as ordinary coffee berries,
but preferably I only reduce the cakes into lumps of much larger size.
The lumps are then roasted in an ordinary revolving coffee roaster just in the
same way as coffee berries are now roasted, and they are subsequently ground to
powder, and the powder may be used either alone as a substitute for coffee, or it
may be used admixed with coffee as desired.
Having thus described my Invention I would have it understood that I claim,―
The manufacture of the new preparation, substantially as herein before described,
to be used as a substitute for coffee.
In witness whereof, I, the said Samuel Trevor Francis, have hereunto set
my hand and seal, this Twenty-fifth day of August, in the year of our
Lord One thousand eight hundred and eighty one.
