page_text: LETTERS PATENT to Henry Martin, of Old Kent Road, in the County of
Surrey, and of 8, Scotts' Yard, in the City of London, for the Invention
of "IMPROVEMENTS IN SEPARATING STARCH FROM GLUTEN, IN APPARATUS USED
THEREIN, AND ALSO IN PREPARING CEMENT FROM GLUTEN."
Sealed the 8th April 1859, and dated the 14th October 1858.
PROVISIONAL SPECIFICATION left by the said Henry Martin, at the
Office of the Commissioners of Patents, with his Petition, on the
14th October 1858.
I, HENRY MARTIN, of Old Kent Road, in the County of Surrey, and of
8, Scotts' Yard, in the City of London, do hereby declare the nature of
the Invention for "IMPROVEMENTS IN SEPARATING STARCH FROM GLUTEN, IN
APPARATUS USED THEREIN, AND ALSO IN PREPARING CEMENT FROM GLUTEN," to bo
as follows:-
This Invention has for its object improvements in separating starch from
gluten, in apparatus used therein, and in preparing cement from gluten. For
these purposes a rectangular trough is used, having wire gauze let in at the
ends and middle, or at other convenient parts. In this trough a reciprocating
frame is used, carrying rollers, by preference four, although other numbers of
rollers may be used. The dough which is to have the starch separated from
the gluten is placed between the two end pairs of rollers, the frame is made to
reciprocate, and a constant flow of water is allowed to flow on the dough,

page_text: which will wash out and separate the starch from the gluten; the wash water
continually flowing through the wire gauze into a suitable vessel to settle, and
then to be treated in the ordinary manner of manufacturing starch. After the
dough has been subjected for a time to the action of the frame of rollers, the
dough, now for the most part gluten, is placed between the ends of the frame
and the ends of the trough, by which the dough or gluten is continually beaten
by the ends of the frame whilst still subject to a constant flow of water. In
order to convert gluten into cement it is combined with stale beer or fermented
liquor and oil.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Martin, in the Great Seal Patent Office on the
14th April 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
MARTIN, of Old Kent Road, in the County of Surrey, and of 8, Scotts' Yard,
in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Martin, Her special licence that I, the said Henry Martin,
my executors, administrators, and assigns, or such others as I, the said Henry
Martin, 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 SEPARATING
STARCH FROM GLUTEN, IN APPARATUS USED THEREIN, AND ALSO IN PREPARING CEMENT
FROM GLUTEN," upon the condition (amongst others) that I, the said Henry
Martin, 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 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 Henry Martin, do hereby declare
the nature of the said Invention, and in what manner the same is to bec

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in separating starch from
gluten, in apparatus used therein, and in preparing cement from gluten. For
these purposes a rectangular trough is used, having wire gauze let in at the
ends and middle or at other convenient parts. In this trough a reciprocating
frame is used, carrying rollers, by preference four, although other number of
rollers may be used. The dough which is to have the starch separated from
the gluten is placed between the two end pairs of rollers, the frame is made to
reciprocate, and a constant flow of water is allowed to flow on the dough,
which will wash out and separate the starch from the gluten; the wash water
continually flowing through the wire gauze into a suitable vessel to settle, and
then to be treated in the ordinary manner of manufacturing starch. After
the dough has been subjected for a time to the action of the frame of rollers,
the dough, now for the most part gluten, is placed between the ends of the
frame and the ends of the trough, by which the dough or gluten is continually
beaten by the ends of the frame whilst still subject to a constant flow of

water.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 is a plan, and Figure 2 a longitudinal section of apparatus con-
structed suitably for carrying out my Invention. a, a, are two troughs, which
are similar to each other and are to be of any convenient length; within each
of these troughs there is a rectangular frame 6, which is caused to move to
and fro within the trough by a crank axis c and connecting rod d. When
two frames are used in two troughs a, as is shown in the Drawing, it is
preferred that the two cranks should be set opposite to each other, as is shown.
Each of the frames & carries the bearings of four or other convenient number
of grooved rollers e, c. At the bottom of each of the troughs a, a, at intervals
there are openings f, f, covered with wire gauze; at the ends of each trough
are applied spring buffing apparatus g, 9, as shown in the Drawing. Below
the troughs is an inclined sieve h of fine wire gauze, and below it an inclined
shoot i, down which the fluid which passes through the sievo h flows, and from
it into any suitable receiving tank, vessel, or cistern, where the starch is
allowed to settle; and then the process of starch making is finished as here-
tofore. j, j, is a perforated pipe above each trough, through which numerous

page_text: jets of water flow on to the dough introduced into the trough, and such jets of
water wash away the starch from the gluten contained in the dough as the
dough is more and more rolled or kneaded by the rollers. The water
carrying the starch with it flows through the openings in the bottom of the
trough on to the inclined sieve h which is below, and if any portion of the
dough or other matter descends which will not pass through the sieve, it will
pass down the inclined sieve to the lower end thereof and fall into a suitable
receiver below, whilst the starch and water will pass through the inclined sieve
on to the inclined shoot i below the sieve h and be conducted into a suitablo
settling tank or vessel. The dough is put into the troughs on the bottom,
between the openings f, and the rolling or kneading process is to be continued
till the water comes off clear and free from starch. The remaining gluten is
then removed from the trough and placed between the ends of the frames and
the buffing apparatus, where it is beaten for several minutes, say twenty
minutes, and is then used for any purpose to which it is applicable.
In carrying out the second part of my Invention, I combine or intimately
mix stalo fermented liquor, such as beer, and also a quantity of oil; and the
relative proportions which I generally employ are, as follows:-Twenty pounds
of gluten, one pint of fermented liquor, and a quarter of a pint of linseed oil.
In witness whereof, I, tho said Henry Martin, have hereunto set my
hand and seal, this Twelfth day of April, in the year of our Lord
One thousand eight hundred and fifty-nine.
