I, GEORGE RYDILL, Auctioneer and Commission Agent, Grove
House, Dewsbury, do hereby declare the nature of the said Invention
for "A NEW METHOD OR METHODS FOR EXTRACTING AND PURIFYING MILL

This Invention consists of a new method or methods for extracting
oily or fatty matter, vegetable substances, particles of dirt, foreign
matter, and dyed colour from flocks, mill waste, refuse, and other
woollen substances containing flock material, for re-dying the same into
other colours and producing therefrom a clean healthy brown and
yellow woollen flock for beds, upholstery, saddlery, and other purposes,
also for producing a woollen material for re-manufacture after having
extracted the oily and other matters by means of high-pressure steam
and powerful presses, carbon, or other methods usually adopted for
that purpose, and for the recovery of a certain fertilising agent.
My Invention consists in the employment of sulphuric acid, hydro-
chloric acid, sulphurous acid, nitromuriatic acid, oxalic acid, nitric acid,
nitros acid, chlorine gas, fustic, American bark, bycroom, tumerick,
flavine, acetic acid, for extracting the oily or fatty matter, vegetable
substances, particles of dirt and foreign matter, and removing died
colours from flock materials, wool, woollen, and woollen waste material
from "woollen mills, called mill waste refuse or shoddy manure, and
other substances containing the same matters.
My Invention further consists in the recovery of the acid waters
employed for the above-named purposes after they have been used for
extracting, purifying, and removing dyed colours, and converting the
same into a fertilising agent for land by mixing with the waste refuse.
Having thus stated in what my Invention consists, I now proceed to
describe the method or methods by which the same may be carried into
effect. I first take the mill waste refuse after it has been cleared of
the oil, which contains all kinds of dyed colours and foreign matter, and
I submit the flock material, wool, woollen, and mill waste material,
called mill waste refuse or slioddy manure, to the centrifugal force of
a shake willey, or cleaner, which forces through small mash wire or
perforated grating foreign matter, particles of dirt, and shive into a
receiver at the back and underneath the willey or cleaner, leaving to
a great extent the small particles of flock material, wool, woollen, and
woollen waste material or mill waste refuse free to a great extent of
refuse and heavy matter. I subject the flock material, wool, woollen,
and mill waste material to a sharp boil in alum water in order to

page_text: in acid water.
Supposing sulphuric acid to be the agent adopted for stripping and
removing those dyed colours and foreign matter I employ for the
reception of the flock, wool, woollen, or mill waste material a cylinderical
or other shaped vessel made of iron, wood, lead, or any other suitable
material having a cover at the top, or worked in an open vessel with
a false perforated bottom. I also fix in this vessel a moveable perforated
bottom with chain attached to be raised or lowered by means of a block
or any other suitable mechanism. I then pour sulphuric acid and water
into a reservoir placed above the receiver at a strength varying from
1 to 8 degrees, when the deluted sulphuric acid and water will flow
down the pipe leading from the reservoir into the cylindrical vessel near
the bottom, having a tap or valve to cut off the supply at will. I then
connect with the interior of the vessel a steam pipe from a boiler with
a tap or valve to regulate the flow of hot steam to heat the sulphuric
acid and water in the cylindrical vessel, which is heated to boiling point
and allowed to act on the flock material, wool, woollen, and woollen.
waste material under pressure or in an open vessel from 4 to 20 minutes
according to the dirty state of the material, which acid is allowed to
act on the vegetable matter which such might contain as cotton shieve
and foreign matter; then the steam supply is cut off and the cover
removed. I then open the tap or valve fixed at the bottom of the
cylindrical vessel, when the acid liquid containing coloured matter is
removed from the woollen waste, flock material, or shoddy manure and
run off through the perforated bottoms into a receiver fixed underneath.
I then raise the wool, woollen waste, flock material, or shoddy manure
in the cylindrical vessel which rests on the moveable false bottom to
the top of the vessel, when it is placed in a hydro-extractor to remove
thoroughly the acid waters it might contain, and I allow a stream of
clean water to act upon it while it is in motion in the hydro-extractor in
order to rinse the same, or it is placed in a cistern to be washed with clean
water in case the first supply from the reservoir has not sufficiently
removed or extracted the dye, colouring matter, and vegetable and
foreign substances. A second supply of sulphuric acid and water is
allowed to run into the cylinderical vessel from the reservoir placed above,
and again heated to boiling point, when the material and liquid are

page_text: removed as in the first process, or the material is raised on the false
moveable bottom as before described and washed and the acid liquid
reused. I then remove the woollen waste, flock material, or shoddy
manure from the hydro-extractor or the wash cistern, which with the
action of the acid water upon it is changed from a dark colour to a light
brown or drab into a vessel having a fixed perforated false bottom and
a moveable perforated bottom and containing diluted nitric acid, nitros
acid, fustic, American bark, bycroom, tumerick, but I prefer nitric acid,
and give the flock material a sharp boil from 5. to 20 minutes, according
to the strength of the liquid, when the action of the nitric acid changes
the light brown or drab flock material to a clear yellow or fawn
colour; and as the liquid becomes exhausted I place the flock -material-
in the oldest vats and change and finish in the newest and strongest,
which gives the finest bloom as a finish. All the liquors pressed or
drawn out by the hydro-extractor from the flock is put back into the
respective vats for re-use.
After the material has attained the proper colour it is raised from the
vessel or vat and allowed to drain, or I immediately place the same in
a hydro-extractor and after the acid water has run out I allow a stream
of clear water to run through it to remove the nitric acid as much as
possible from it. I then remove the woollen material or flock stuff
in the hydro-extractor and place the same in a vessel to be steeped in
water under pressure, which pressure is obtained by a hydraulic pump
or artificial means; and from time to time I let off the water and refill
with fresh water until the effect of the acid to a great extent is removed.
I then let in upon the woollen flock material a weak alkali or alkalies
for instance, caustic soda, ammonia, which destroy any acid that may
have been left. I then remove the flock material into a hydro-extractor
or cistern and allow clean water to act upon it for a short time. I
then cut off the water and allow the material to throw off as much
of its moisture as possible. I then raise the material and dry in a
stove or by means of hot air until it is thoroughly dry. I then place the
woollen flock material in a shake willey to remove any small particles of
dust, or shive, or foreign matter, which then leaves a clean healthy woollen
flock for beds and other purposes. I also take the woollen waste material
shaken out of the mill waste refuse or shoddy manure in the shake willey
and place it in an ordinary dye pan with diluted sulphuric acid and water

page_text: and boil the same for from 5 to 20 minutes according to the strength
of the liquid to strip the colour. I then allow the liquor to be let off
and rinsed well with cold water. I then from a reservoir allow a weak
solution of nitric acid and water to run upon the material and heat
the same to boiling point until the yellow colour is produced, and then
rinse, wash, and dry.
By another method I take the material from a willey and steep the
same in sulphuric acid or hydrochloric acid of from 2 to 10 degrees,
drain and dry in the acid state to destroy the, vegetable matter, and
then wash and dry as before. Or I allow the acid gases to act upon
the flock material from a retort to destroy the foreign matter, and then
wash and dry as before.

page_text: Invention, 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 George Rydill, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement :—
This Invention consists of a new method or methods for extracting
oily or fatty matter, vegetable substances, particles of dirt, foreign
matter, and dyed colours from flocks, mill waste refuse, and other
woollen substances containing flock material, for re-dyeing the same
into other colours, and producing therefrom a clean healthy brown and
yellow woollen flock for beds, upholstery, saddlery, and other purposes,
also for producing a woollen material for re-manufacture after having.
extracted the oily and other matters by means of high-pressure steam
and powerful presses, carbon, or other methods usually adopted for that
purpose, and for the recovery of a certain fertilizing agent.
My Invention consists in the employment of sulphuric acid, hydro-
chloric acid, sulphurous acid, nitromuriatic acid, oxalic acid, nitric acid,
nitros acid, chlorine gas, fustic, American bark, bycroom, tumerick,
flavine, or acetic acid for extracting the oily or fatty matter, vegetable
substances, particles of dirt, and foreign matter, and removing dyed
colors from flock material, wool, woollen, and woollen waste material
from woollen mills, called mill waste refuse or shoddy manure, and other
substances containing the same matters.
My Invention further consists in the recovery of the acid waters
employed for the above-named purposes after they have been used
for extracting, purifying, and removing dyed colours, and converting
the same into a fertilising agent for land by mixing with the waste
refuse.
Having thus stated in what my Invention consists I now proceed to
describe the method or methods by which the same may be carried into
effect. I first take the mill waste refuse after it has been cleared of the

page_text: oil, which contains all kinds of dyed colours and foreign matter, and
I submit the flock material, wool, woollen, and mill waste material
called mill waste refuse or shoddy manure, to the centrifugal force of
a shake willey or cleaner, which forces through small mesh wire or per-
forated grating foreign matter, particles of dirt, and shive into a receiver
at the back and underneath the willey or cleaner, leaving to a great
extent the small particles of flock material, wool, woollen, and woollen
waste material, or mill waste refuse, free to a great extent of refuse and
heavy matter.
I subject the flock material, wool, woollen and mill
waste material to a sharp boil in alum water in order to remove the
coloured matter and dirt. I then drain and place the same in acid water.
Supposing sulphuric acid to be the agent adopted for stripping and
removing those dyed colours and foreign matter I employ for the
reception of the flock, wool, woollen or mill waste material a cylindrical
or other shaped vessel made of ironwork, lead, or any other suitable
material having a cover at the top, or worked in an open vessel with a
false perforated bottom. I also fix in this vessel a moveable perforated
bottom with chain attached, to be raised or lowered by means of a block
or any other suitable mechanism. I then pour sulphuric acid and water
into a reservoir placed above the receiver at a strength varying from
1 to 8 degrees, when the diluted sulphuric acid and water will flow
down the pipe leading from the reservoir into the cylindrical vessel near
the bottom, having a tap or valve to cut off the supply at will. I
then connect with the interior of the vessel a steam pipe from a boiler
with a tap or valve to regulate the flow of hot steam to heat the sul-
phuric acid and water in the cylindrical vessel, which is heated to
boiling point and allowed to act on the flock material, wool, woollen,
and woollen waste material under pressure, or in an open vessel from
4 to 20 minutes according to the dirty state of the material, which acid
is allowed to act on the vegetable matter which such might contain, as
cotton shive and foreign matter; then the steam supply is cut off and
the cover removed. I then open the tap or valve fixed at the bottom
of the cylindrical vessel, when the acid liquid containing coloured
matter is removed from the woollen waste, flock material, or shoddy
manure and run off through the perforated bottoms into a receiver fixed
underneath. I then raise the wool, woollen waste, flock material or
shoddy manure in the cylindrical vessel which rests on the moveable

page_text: false bottom to the top of the vessel, when it is placed in a nyaro-
extractor to remove thoroughly the acid waters it might contain, and I
allow a stream of clean water to act upon it while it is in motion in
the hydro-extractor in order to rinse the same, or it is placed in a cistern
to be washed with clean water in case the first supply from the reservoir
has not sufficiently removed or extracted the dye colouring matter and
vegetable and foreign substances. A second supply of sulphuric acid
and water is allowed to run into the cylindrical vessel from the reservoir
placed above and again heated to boiling point, when the material and
liquid are removed, as in the first process, or the material is raised on
the false moveable bottom; as before described, and washed and the
acid liquid reused. I then remove the woollen waste, flock material,
or shoddy manure from the hydro-extractor or the washi cistern, which
with the action of the acid water upon it is changed from a dark colour
to a light brown or drab, into a vessel having a fixed perforated falsc
bottom and a moveable perforated bottom, and containing a diluted
nitric acid, nitros acid, fustic, American bark, bycroom, or tumerick, but
I prefer nitric acid, and give the flock material a sharp boil for from 5
to 20 minutes according to the strength of the liquid, when the action
of the nitric acid changes the light brown or drab flock material to a
clear yellow or fawn colour, and as the liquor becomes exhausted I
place the flock material in the oldest vats and change and finish
in the newest and strongest, which gives the finest bloom as a finish.
All the liquors pressed or drawn out by the hydro-extractor from the
flock material is put back into the respective vats for re-use.
After the material has attained the proper colour it is raised from the
vessel or vat and allowed to drain, or I immediately place the same in
a hydro-extractor, and after the acid water has run out I allow a stream
of clear water to run through it to remove the nitric acid as much as
possible from it. I then remove the woollen material or flock stuff
in the hydro-extractor and place the same in a vessel to be steeped in
water under pressure, which pressure is obtained by a hydraulic pump
or artificial means, and from time to time I let off the water and refill
with fresh water until the effect of the acid to a great extent is removed.
I then let in upon the woollen flock material a weak alkali or alkalies,
for instance, caustic soda or ammonia, which destroy any acid that
may have been left.
I then remove the flock material into a hydro-

page_text: extractor or cistern, and allow clean water to act upon it for a short
time. I then cut off the water and allow the material to throw off as
much of its moisture as possible. I then raise the material and dry in a
stove or by means of hot air until it is thoroughly dry. I then place the
woollen flock material in a shake willey to remove any small particles of
dust or shive or foreign matter, which then leaves a clean healthy woollen
flock for beds and other purposes.. I also take the woollen waste material
shaken out of the mill, waste refuse, or shoddy manure in the shake
willey and place it in an ordinary dye pan with diluted sulphuric acid
and water, and boil the same for from 5 to 20 minutes according to the
strength of the liquid to strip the colour. I then allow the liquor to be
let off and rinsed well with cold water. I then from a reservoir allow a
weak solution of nitric acid and water to run upon the material and
heat the same to boiling point until the yellow colour is produced, and
then rinse, wash, and dry.
By another method I take the material from a willey and steep the
same in sulphuric acid or hydrochloric acid of from 2 to 10 degrees,
drain and dry in the acid state to destroy the vegetable matter, and then
wash and dry as before. Or I allow the acid gases to act upon the flock
material from a retort to destroy the foreign matter, and then wash and
dry as before.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I do not in
any way confine myself to the particular methods herein-before described
for carrying my Invention into effect, and moreover I do not confine
myself to any particular construction or arrangement of apparatus in
connection therewith; but I claim,―
First. The extracting of dyed colouring matter and foreign substances
from mill waste refuse in a closed vessel under pressure by means of
diluted sulphuric acid, hydrochloric acid, sulphurous acid, nitric acid, or
alum, in the manner herein-before described.
Second. Washing the mill waste refuse or flock material in a closed
vessel under pressure with diluted caustic soda and ammonia, in the
manner herein-before described.
Third. Dyeing the mill waste refuse or flock material a yellow colour
by means of nitric acid, American bark, or bycroom, in the manner
herein-before described.

page_text: Fourth. The employment of the spent acid liquids as a fertilizing
agent for land by mixing with the mill waste refuse, in the manner
herein-before described.
Fifth. Extracting vegetable matter from mill waste refuse by means
of sulphuric acid, hydrochloric acid, or sulphurous acid, in the manner
herein-before described.
In witness whereof, I, the said George Rydill, have hercunto set
my hand and seal, this Twentieth day of August, in the year of
our Lord One thousand eight hundred and seventy.
