PROVISIONAL SPECIFICATION.
A New or Improved Substance or Product for Use in Finishing
Fabrics, Yarns, and Threads.
We WILLIAM PATERSON of the Phoenix Chemical Works, Maryhill Glasgow,
Chemist, and ROBERT STARKE of 43 West Regent Street Glasgow, in the County of
Lanark North Britain, Writer do hereby declare the nature of this invention to be as
follows:-
This Invention which relates to a New or Improved Substance or product to be
known as Bicextine for use in the finishing of manufactured fabrics Yarns, &
Thread, has for its object to produce a superior & cheaper finishing Substance than
hitherto used, and of greater strength and durability.
First. We take a suitable quantity of cereals, roots, or seeds, such as Maize, Indian
Corn, Oats, Rye, Potatoes Rice, Barley, or any of the aforesaid cereals, or substances,
or any suitable cereal, root, or farinaceous substance containing Starch, and Glutinous
material, or their compounds, partly or wholly malted in a vat, mash-tun, Tank, or
other suitable vessel. Such malting process may take place by a combination of any
of the aforesaid substances or collectively or by any single substance to obtain the
soluble ingredients therefrom.
Second. Having determined which is the most suitable class of any of the aforesaid
substances for the manufacture of the Bicextine we take a certain quantity of water,
at a suitable temperature to a certain amount of any of the above named materials
either singly or collectively with a proportion of malted seed-Barley preferred-and
mix the same together.
This
Third. Whilst the resulting product obtained from the above is in every way well
fitted for the purpose for which it is intended, I preferably take-instead of water a
solution of Gluten obtained in one of the first processes in the manufacture of Starch,
from any of the cereals above mentioned, or any other convenient manner.
solution of "Gluten "-in certain quantities-is mixed with an equivalent proportion
of a mixture of the cereals, roots, seeds, and malt, above mentioned, and subjected
to a macerating process, at a suitable temperature, so as to fully extract all the soluble
ingredients, or valuable material, the resulting product of this mixture, after having
gone through the process of purification, and filtration, is placed in a copper vacuum
pan, Copper Boiler, Copper Tank or any other suitable vessel, and is boiled down to
the desired consistency.
The use of the "gluten" adds materially to the strength of the Bicextine, and
consequently strength and durability to the fabric, to which it is applied by the
Finishers of manufactured cloth.

A New or Improved Substance or Product for Use in Finishing

We, WILLIAM PATERSON of the Phoenix Chemical Works, Maryhill, Glasgow
Chemist and ROBERT STARKE of 43 West Regent Street, Glasgow, in the County of
Lanark, North Britain, Writer, 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 :-

D

page_text: known as "Bicextine for use in the finishing of manufactured fabrics, yarns and
threads has for its object to produce a superior and cheaper finishing substance than
hitherto used and of greater strength and durability.
In carrying out our Invention we take a suitable quantity of cereals, roots or
seeds such as maize, Oats, Rye, Potatoes, Rice, Barley, or any of the aforesaid cereals
or substances, or any suitable cereal root, or farinaceous substance containing starch
and glutinous material or their compounds. These after being prepared or ground
may be partly or wholly mashed in a mash-tun, tank or other suitable vessel which
process, may take place by a combination of any of the aforesaid substances, or
collectively or by any single substance to obtain the soluble ingredients therefrom.
According to our experience to produce the substance under our invention we find
the following to give most satisfactory results. We take equal parts of crushed malted
harley and roughly ground maize the proportion being say quarters of barley to
5 qrs. of maize, the quarter being 336 lbs. The 5 quarters of malted barley is mashed
in a mash tun with say 60 gallons of water, per quarter of malt operated upon, the
water being first heated to a temperature of 140 degrees Fahrenheit and gradually
increased to a temperature of 152°, one hour being taken to increase the temperature
from the lower to the higher degree to effect the solution of the starch. We also
take 5 quarters of the ground maize and place it in another vat or vessel to be heated
or mashed gradually to a temperature ef 190° Fahrenheit with 36 gallons of water
per quarter. This mixture after being allowed to cool down to about 150° is
gradually poured into the mash-tun containing the mashed malt, and mixed thoroughly
with the mashed malt by the regular mashing and mixing method for one and a
half hours. The combined mixture in this mash-tun after being allowed to settle
for the purpose of the solution being. run off in a clear state, is thereafter drawn
into a copper vacuum pan, copper tank or other suitable vessel and boiled down
usually to the thickness of ordinary syrup or thereabout which produces the substance
called Bicextine to be used for the purposes herein before described. If desirable
however the concentration can be carried on until the material is formed or worked
into an almost solid state.
Instead of using water to mix with either of the cereals above described we may
take or use a solution of gluten obtained in one of the first processes in the
manufacture of starch, corn flour etc. say 70 gallons per quarter and with the like
material and operation as before described, produce the substance "Bicextine." If
necessary the caustic soda or other alkali used in dissolving out the gluten from the
grain obtained in the manufacture of starch, corn flour &c. may be partially or
wholly neutralised with either sulphuric, nitric or hydrochloric acid.
The foregoing result we have found to be very successful but it is to be understood
that the quantities of the cereals used as above may vary, thus should the malted
cereal be of good quality 1 portion of malted barley to 3 portions of ground maize
will be found to produce results equal to those before referred to.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
The manufacture or production of the substance known as Bicextine by employing
and subjecting the malted and unmalted cereals in the proportions named to the
process and operation substantially as and for the purposes hereinbefore set forth and
described.
