IMPROVEMENTS IN THE Manufacture OF DIETETIC FOODS
Year: 1875

page_text: LETTERS PATENT to Campbell Morfit, of Baltimore, in the State of
Maryland, in the United States of America, but at present of
23, Southampton Buildings, in the County of Middlesex, Consulting
Chemist, for the Invention of "IMPROVEMENTS IN THE Manufacture
OF DIETETIC FOODS."
Sealed the 7th April 1876, and dated the 12th November 1875.
PROVISIONAL SPECIFICATION left by the said Campbell Morfit at the
Office of the Commissioners of Patents, with his Petition, on the
12th November 1875.
I, CAMPBELL MORFIT, of Baltimore, in the State of Maryland, in the
United States of America, but at present of 23, Southampton Buildings,
in the County of Middlesex, Consulting Chemist, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
DIETETIC FOODS," to be as follows :—
My Invention consists in the use of cows' or goats' milk condensed by
evaporation (so as to deprive it of the greater part of its natural water
without impairing its normal condition otherwise) in combination with

page_text: the flours and meals of wheat, rye, oats, maize, rice, millet, peas, beans,
and lentils, singly or intermixed in pairs or greater numbers among
themselves or with gluten, for the manufacture of a complete dietetic
food containing in eminent proportions and agreeable conditions all the
elements necessary for nourishing the human body comfortably and
sustaining its vital functions in normal condition.
The food aforesaid may be prepared in the forms of biscuits, biscuit
powder, macaroni, vermicelli, pâtes, and granules, by mixing the selected
meal or meals with the milk, kneading thoroughly into dough, shaping
it and baking or carefully drying, and cooking, and granulating it by
the usual mechanical means according to the form of product required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Campbell Morfit in the Great Seal Patent Office
on the 12th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CAMPBELL
MORFIT, of Baltimore, in the State of Maryland, in the United States
of America, but at present of 23, Southampton Buildings, in the County
of Middlesex, Consulting Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of November, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Campbell Morfit, Her special license,
that I, the said Campbell Morfit, my executors, administrators, and
assigns, or such others as I, the said Campbell Morfit, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
The ManufacturE OF DIETETIC FOODS," upon the condition (amongst others)
that I, the said Campbell Morfit, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said

page_text: Invention and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Campbell Morfit, 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 thereof, that is to say :—
My Invention consists in the use of cows' or goats' milk condensed
by judicious evaporation in vacuo or otherwise (so as to deprive it of the
greater part of its natural water without impairing its normal condition
otherwise) in combination with flours and meals of wheat, rye, oats,
maize, rice, millet, peas, beans, and lentils, singly or intermixed in pairs
or greater numbers among themselves, or with gluten for the manu-
facture of a complete dietetic food containing in eminent proportions
and agreeable conditions all the elements necessary for nourishing the
human body comfortably and sustaining the vital functions in normál
condition.
I carry my Invention into effect by first taking the grain of the
wheat, oats, or other one of the farinaceous articles above noted, and
after removing the husk grinding it entirely into a whole meal which
will be free from spicular particles and yet have a sufficient degree of
coarseness to regulate the action of the bowels without producing any
irritating effect. In other words the proper degree of coarseness will be
adjusted when the meal is ground so that it will all pass through a sieve
of about 17 round or square meshes to the running, or about 289 to the
square inch. If more than one kind of grain is to be used in the pro-
duction of the food under process then the required proportion of each
in the form of meal as above ground is to be thoroughly mixed by the
hand or suitable mechanical means. The next step is to make the
weighed portion of the meal into a dough with as much of the condensed
milk, produced as above described, as may be required for the purpose,
and then briskly knead the mass for at least thirty minutes. The milk
must be free from all sugar other than its natural constituent lactose.
The dough is now ready to be converted into maccaroni, granules, or
biscuits according to whichever of these forms it is desired to give the
product. If the paste or dough is to be made into maccaroni then it is

page_text: only necessary to draw it into tubes or into ribbons after the known
manner and by the known mechanical means employed for making that
article and drying carefully. So also to make the dough into granules
it must be passed through a granulating machine of suitable known
construction, such for instance as is used for making "French tapioca."
The granules thus formed are to be carefully dried in a well ventilated
hot-air chamber and packed for market.
To convert the dough into biscuits it is only necessary to roll it out
into sheets, cut into forms, prick the latter, and bake them sufficiently
in the usual manner and by the usual means.
Sometimes it may be desired to impart greater lightness to the
product and even yet further improve its flesh-forming property. For
these purposes gluten freshly made by removing the starch from wheat.
flour dough in the usual manner of kneading it in water is to be mixed
with the meal or meals and in the required proportion just previous to
adding in the milk condensed, as herein described, for making the
dough.
:
Having thus described the nature of my said Invention, and the
mode in which I carry the same into effect, I would have it understood
that what I claim is, the combination of wheat, oat, and other grain:
meals of adjusted coarseness, and condensed cows' or goats' milk with
or without the addition of gluten for the manufacture of a complete
dietetic food, in the manner substantially as herein set forth and
described.
In witness whereof, I, the said Campbell Morfit, have hereunto
set. my hand and seal, this Tenth day of May, in the year of
our Lord One thousand eight hundred and seventy-six.
