We MILES ASHWORTH, of Falinge Road, Rochdale, Cotton Waste Merchant, and
ROBERT WILD, of 3, Carlisle Street, Littleborough, Mechanical Engineer, both in
the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
Our Invention refers to and consists in the first part, to the manufacture, use, and
employment, of a mixture, for Washing, Scouring and Boiling of fibres, fibrous
materials and textile fabrics, and the stripping of Fibres from Hides or Skins; or such
like materials as Cotton, Wool, Silk, Flax, Hemp, Jute, Rhea-Ramie and China Grass,
Esparto, Yucca, Rags and other fibres, or fibrous materials.
The said mixture, either in the dry or liquid form, being composed of Bi-Borate of
Soda, Phosphate of Soda, Phosphate of Lime, Soda Ash or Potash, Potassium
Chlorate or Chlorate of Potass, and Sulphate of Magnesia; and with or without any
Soap, Caustic Soda, or Caustic Potash; by preference in the following proportions,
that is to say, by weight, One pound of Bi-Borate of Soda; Two pounds of Phosphate
of Soda; Two pounds of Phosphate of Lime; Seven poun is of Soda Ash or Potash;
Eight ounces of Potassium Chlorate or Chlorate of Potass; and four ounces of
Sulphate of Magnesia; and with or without Soap as may be desired and thought best;
such Soap being used in various proportions as may be required.
We do not confine ourselves to these proportions absolutely, as the same be
varied, and one or more of the said ingredients may be omitted in some cases as
required.
The second part of our Invention refers to the manufacture, use, and employment,
of a mixture, for the Bleaching of Fibres, Fibrous Materials, and Textile Fabrics; the
said mixture being either in the dry or liquid form composed of Bi-Borate of Soda ;
Phosphate of Soda; Potassium Chlorate; Chloride of Sodium; and Carbonate of

page_text: Soda by preference in the following proportions, that is to say, by weight. One
pound of Bi-Borate of Soda; Three pounds of Phosphate of Soda; Three pounds of
Potassium Chlorate; Five pounds of Chloride of Sodium; and Seven pounds of
Carbonate of Soda; the same to be used to every Five hundred gallons of water,
more or less.
We however do not confine ourselves absolutely to these proportions, as the same
may in some cases require to be varied, and one or more of the said ingredients may
be omitted as required.
The said ingredients for the said mixtures, are all crushed and ground into a fine
powder, and thoroughly amalgamated together, and thereafter packed in the usual
way, in casks, bags, and packets, for the trades and public use.
In carrying out our Invention for Bleach, Print, and Paper, or other works, where
washing, scouring, boiling and bleaching is done; in the process of Washing, Scouring
and Boiling, we simply, wash, scour or boil the fibres, fibrous materials, or textile
fabrics, in a cold, warm, hot or boiling solution of the said mixture hereinbefore
described of a more or less strength or Twaddle, and for a longer or shorter period,
as may be required; after washing, scouring, or boiling of the goods or materials that
are under treatment, we pass or run such goods or materials thereafter, through a pair
of press howls, rollers, pullies, or squeezers; and thereafter wash the goods or
materials in clear or clean water, and pass them again through press bowls, rollers,
pullies or squeezers; and thereafter pass the goods under treatinent into the ordinary
style of Bleach Tank or Tanks; (or otherwise) first of which, the goods are placed in
the Tank or Tanks, containing as beforementioned the solution mixture for Bleaching,
consisting of Bi-Borate of Soda, Phosphate of Soda, Potassium Chlorate, Chloride of
Sodium, and Carbonate of Soda; after the goods under treatment, have been in the
Bleaching liquid for a longer or shorter period as may be required; we then pass the
goods through a pair of press bowls, rollers, pullies, or squeezers, then wash the said
goods, and pass them through press bowls, rollers, pullios, or squeezers, and thence
pass them into the Tank or Tanks, containing an Acid solution, as is at present done
in the ordinary way of bleaching; after the goods have been sufficiently long (as may
be deemed best) in the said Tank or Tanks containing the Acid solution; we then pass
the goods through a pair of press bowls, rollers, pulleys or squeezers; and thereafter
wash the said goods under treatment in clean or clear water, and again run the goods
through another pair of press bowls, rollers, pullies or squeezers and thereafter as
circumstances may require, we pass the said goods through a hot or cold solution Blue
and Soap, as at present is done, or of a solution of Blue, or of Soap, as the case may
call forth, and again run the goods through press bowls, rollers, pullies or squeezers;
and thereafter dry the said goods under treatment by any of the well known methods
and plant therefore as is at present done.
For the Stripping of Fibres from Hides or Skins; we steep such Hides or Skins,
in a solution consisting of the mixture employed for the washing, scouring, and
boiling of fibres, fibrous materials, and textile fabrics, as hereinbefore described;
the solution may be hot or cold as desired.
By the said process, and the employment and use of the said mixtures hereinbefore
described, we accomplish great saving in time, cost and labour of Washing, Scouring,
Boiling and Bleaching of Fibres, Fibrous Materials, and Textile Fabrics, and the
Stripping of Fibres from Hides or Skins.

We MILES ASHWORTH of Falinge Road Rochdale, Cotton Waste Merchant and
ROBERT WILD of 3 Carlisle Street, Littleborough, Mechanical Engineer, both in the
County of Lancaster do hereby declare the nature of our said invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
Our invention refers to and consists in the first part in the manufacture use and
employment of a mixture for the washing, scouring and boiling of fibres, fibrous
materials and textile fabrics or such like materials as cotton, wool, silk, flax, hemp,
jute, (Rhea-Ramie), China grass, Esparto, Yucca, rags and other fibres or fibrous
materials applicable also in the stripping of fibres from Hides or Skins.
The said mixture either in the dry or liquid form is composed of Bi Borate of Soda
Phosphate of Soda, Phosphate of Lime, Soda Ash or Potash, Potassium Chlorate or
Chlorate of Potass and Sulphate of Magnesia and with or without any soap. Caustic
Soda or Caustic Potash by preference in the following proportions that is to say by
weight one pound of Bi-Borate of Soda, two pounds of Phosphate of Soda, two pounds
of Phosphate of Lime, seven pounds of Soda ash or Potash Eight ounces of Potassium
Chlorate or Chlorate of Potass and four ounces of Sulphate of Magnesia and with or
without soap as may be desired and thought best such soap being used in various
proportions as may be required.
This compound is hereinafter referred to as the washing and scouring mixture.
The second part of our invention refers to the manufacture, use and employment of
a mixture for the bleaching of fibres, fibrous materials and textile fabrics the said
mixture being either in the dry or liquid form and composed of Bi-Borate of Soda,
Phosphate of Soda, Potassium Chlorate, Chloride of Sodium and Carbonate of Soda
by preference in the following proportions, that is to say by weight one pound of
Bi-Borate of Soda, three pounds of Phosphate of Soda, three pounds of Potassium
Chlorate five pounds of Chloride of Sodium and seven pounds of Carbonate of Soda
the same to be used to every five hundred gallons of water more or less and which
is hereinafter referred to as one bleaching solution.
The said ingredients for the said mixtures are all crushed and ground into a fine
powder and thoroughly amalgamated together and thereafter packed in the usual way
in casks, bags and packets for the trades and public use.
In carrying out our invention for bleach, Print and Paper or other Works (where
washing, scouring, boiling and bleaching is done) in the process of washing, scouring
and boiling we simply wash, scour or boil the fibres, fibrous materials or textile
fabrics in a cold, warm, hot or boiling solution of the aforesaid washing and scouring
mixture of a more or less strength or twaddle and for a longer or shorter period as

page_text: may be required and after so washing, scouring and boiling such goods or materials
we pass or run the same through a pair of press bowls, rollers, pullies or squeezers
and thereafter wash such goods or materials in clear or clean water.
We then pass
them again through press bowls, rollers, pullies or squeezers after which such goods
are introduced into the ordinary style of bleach tank or tanks (or otherwise) the
first of which contains our bleaching solution consisting of Bi-Borate of Soda,
Phosphate of Soda, Potassium Chlorate," Chloride of Sodium and Carbonate of Soda
as aforesaid. After the goods under treatment have been in the bleaching liquid for
a longer or shorter period as may be required to complete the bleaching operation
we then pass them through a pair of press bowls, rollers, pullies or squeezers then
wash the said goods and pass them through press bowls, rollers, pullies or squeezers and
thence pass them into the tank or tanks containing an acid solution as is at present
done in the ordinary way of bleaching after the goods have been sufficiently long
(as may be deemed best) in the said tank or tanks containing the acid solution, we
then pass the goods through a pair of press bowls rollers pullies or squeezers and
thereafter wash the said goods in clean or clear water and again run them through
another pair of press bowls, rollers, pullies or squeezers and thereafter as circumstances
may require, we pass the said goods through a hot or cold solution of blue and
soap as at present is done or through a solution of blue or of soap as the case may
be and again run the goods through press bowls, rollers, pullies or squeezers and
finally dry the said goods under treatment by any of the well known methods and
plant therefor as is at present done.
For the stripping of fibres from Hides or Skins we steep such Hides or Skins in
a solution consisting of the washing and scouring mixture as herein before described,
the solution may be hot or cold as desired.
By the said process, and the employment and use of the said mixtures hereinbefore
described we accomplish great saving in time, cost and labour in the washing,
scouring, boiling and bleaching of fibres, fibrous materials and textile fabrics and in
the stripping of fibres from Hides or Skins.
We do not confine ourselves to the exact proportion of the ingredients forming
our improved mixture hereinbefore described as the same may be considerably
varied without departing from our invention nor in such mixtures do we bind
ourselves to the employment of all the ingredients hereinbefore described as in some
cases one or more of the said ingredients may be omitted.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
