PROVISIONAL SPECIFICATION:
Improvements in or connected with Flour, Meal, and other Bread
Stuffs.
I, LAVINIA RAWSTHORN, of Greenbank Flour Mill, Preston, in the County of
Lancaster, Miller, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to produce a bread stuff from flour meal or the
like containing special nourishing and digestive properties.
It consists essentially in the combination with flour whole meal or other similar
products preferably during manufacture of certain proportions of hypophosphites of
Iron lime soda and similar salts.
In carrying out the invention it is preferred to use two or more of these salts, for
whole meal hypophosphite of iron, hypophosphite of lime and hypophosphite of
soda and for white flour hypophosphite of lime and hypophosphite of soda with the
addition of sugar of milk.
In addition to or instead of these other suitable hypophosphites may be
employed.
.
The hypophosphites are preferably mixed or incorporated with the meal flour or
the like during the process of grinding or at other convenient stage during
manufacture so as to be thoroughly and evenly mixed therewith.

COMPLETE SPECIFICATION.
Improvements in or connected with Flour, Meal, and other Bread
Stuffs.
I, LAVINIA RAWSTHORN, of Greenbank Flour Mill, Preston, in the County of
Lancaster, Miller, 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 this invention is to produce a bread stuff in the form of flour meal
or the like containing special nourishing and digestive properties.
It consists essentially in the combination with flour whole meal or other similar
products, preferably during manufacture of certain proportions of hypophosphites of
iron alone or in conjunction with hypophosphites of lime and soda."
In carrying out the invention I prefer to use in conjunction with the hypo-
phosphite of iron the hypophosphites of both lime and soda though one of them
only may be used or both may be dispensed with.
prepare white flour and whole wheat flour or meal with these ingredients added
thereto in suitable proportions.

page_text: ingredients may if found desirable also be added but I consider it better not to add
any other ingredients to the flour.
->
The hypophosphites of iron lime or soda are finely ground or pulverised and are
worked into the flour or meal during the process of grinding so that they are well
and evenly mixed and distributed. If found convenient, however they may be
mixed at any other stage during or after manufacture so as to be thoroughly and
evenly mixed therewith.
I thus produce a flour of increased food value especially in regard to bone and
muscle forming constituents which will be found very nutritious for growing and
delicate children and a most strengthening, sustaining and invigorating food.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the manufacture, or preparation for consumption, of white flour or whole
wheat flour the combination therewith of hypophosphite of iron either alone or in
conjunction with hypophosphites. of lime or soda substantially as described.
2. The combination with white flour or whole wheat flour of hypophosphite of
iron hypophosphite of lime and hypophosphite of soda substantially as and for the
purpose described.
