page_text: I JOHN CHARLES WILLIAM STANLEY of 41 Barnsdale Road in the County of
Middlesex Gentleman do hereby declare the nature of this invention to be as
follows:-
The object of this invention is for the treatment of cotton and other fibrous
materials but preferably that which can be obtained as refuse containing leaf seed
and other impurities to clean it and make it suitable for paper making and other
useful purposes. If the cotton be very seedy and leafy I pass it through an
ordinary machine known as a gin which will remove a quantity of the seed but to
more perfectly cleanse it I subject it to a further treatment in a breaker which
machine is well known in the cotton trade and consists of a rapidly revolving
drum with projecting spikes which as the drum revolves pass between fixed spikes
in the casing of the machine. The cotton is then dusted and is boiled with water
or a weak solution of alkali or lime may be used; this boiling may be continued
until the particles of leaf &c are soft. After the boiling or in the same vessel
I then mix chalk fine sand or other mineral with the cotton; it is then thoroughly
crushed which may be effected by rollers or ordinary horizontal stones care being
taken that the fibres of the cotton are not broken up fine but only subjected to a
rubbing action. It is then put into a drum or flat strainer working in water
and the crushed leaf mineral &c well washed from the cotton. Should the first
grinding not have crushed all the impurities the operations of grinding and
washing may be repeated until the cotton is perfectly clean. It is then in a
condition for sale, but for the requirements of paper makers the fibre of the cotton
can be reduced into a finer state of pulp in a paper maker's rag engine and if
desired be bleached by the methods now generally in use. For convenience of
transport the excess of moisture can be removed by pressure or the pulp can be
converted into paper by being run over a paper machine.

Middlesex, Gentleman 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 the treatment of cotton and other: fibrous
materials but preferably that which can be obtained as refuse containing leaf seed
and other impurities to clean it and make it suitable for paper making and other
useful purposes.
If the cotton be very seedy and leafy I pass it through an
ordinary machine known as a gin which will remove a quantity of the seed but to
more perfectly cleanse it I subject it to a further treatment in a breaking machine
consisting of a rapidly revolving drum with projecting spikes which as the drum
revolves pass between fixed spikes in the casing of the machine. The cotton is
then dusted and is boiled with water or a weak solution of alkali or lime may be
used; this boiling may be continued until the particles of leaf &c are soft.
After the boiling or in the same vessel I then mix chalk, fine sand or other
mineral with the cotton; it is then thoroughly crushed or ground which may be
effected by rollers or ordinary horizontal stones care being taken that the fibres of
the cotton are not broken up fine but only subjected to a rubbing action. It is
then put into a drum or flat strainer and worked in water and the crushed leaf
seed mineral &c well washed from the cotton. Should the first grinding not have
crushed all the impurities the operations of grinding and washing may be repeated
until the cotton is perfectly clean. It is then in a condition for sale but for the
requirements of paper-makers the fibre of the cotton can be reduced into a finer
state of pulp in a paper-makers rag engine and if desired be bleached by the
methods now generally in use. For convenience of transport the excess of moisture
can be removed by pressure or the pulp can be converted into paper by being run
over a paper engine.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-

1. In the treatment of cotton and other fibrous materials the method of removing
the fine particles of fibre from the leaves and seeds by the abrading action of
mineral matter mixed with the leaves and crushed or ground with them substan-
tially as specified.
2. In the treatment of cotton and other fibrous materials the method of removing
the broken leaves and mineral matter by sifting in water substantially as specified.

page_text: 3. The complete method or process for treating cotton and other fibrous materials
consisting in
(a) Passing the material through an ordinary "gin" to remove a portion of
the seed and other foreign substance.
(b) Passing through a "breaker."
(c) Dusting and boiling in water or a weak alkaline solution.
(d) Mixing with chalk fine sand or other mineral.
(e) Crushing or grinding and
f) Sifting in water.
