The object of my Invention is the treatment of rags and other fibrous materials
after the process known as "extracting" or destroying vegetable matter in rags
composed of cotton and woollen; and which is now done by immersing the said
rags in a preparation of sulphuric acid and called the cold process.
For this purpose of carrying out my Invention I employ a cylindrical boiler,
having a flue or chainber therein. The boiler is filled with water or steam for the
purpose of heating the chamber, in which is placed a perforated cylindrical cage,
caused to revolve by suitable gearing.
Rags to be treated after the extracting or destroying process are placed within
the revolving cage and after each end of the beated chamber has been closed, the
cage is set in motion, slowly whereby the material is carried partially around
within the cage, partitions, spikes, or similar devices, being fixed therein for that
purpose. When the material is sufficiently dried, the rotary motion of the cage is
considerably increased which converts the machine into a willey or shaker and by
means of spikes (fixed on bars running lengthwise of the machine) in conjunction
with spikes fixed on the moving cage, the material is willeyed or shaken whilst
the perforations made in the cage allows the dust or refuse matter to escape into
the outer chamber. When the fibre is sufficiently willeyed the rotary motion
of the cage is reduced and I introduce therein a liquid solution composed of steam
and soda, soda ash and common whiting or chalk which destroys any acil left in
the animal matter after the extracting process.
°
The method of obtaining this mixture consists in the employment of a zigzag
or other form of pipe passing through a steam box for heating the alkali solution
within the said pipe, whilst another pipe having steam therein, is in connection
with the said alkali pipe so that the two elements can be combined when necessary,
suitable tops or valves being arranged for supplying the mixtures as and when
required. When the acids in the fibre have been destroyed, the cage continues to
revolve and in addition thereto, an exhaust fan is employed for exhausting the
condensed steam arising from the dried fibre, air being admitted at the opposite end
of the machine, and drawn out by the fan, whereby the fibre is thoroughly dried
and made ready for use. By the employment of this form and construction of
apparatus, and the method of treating rags as herein described, the various
processes are effectually accomplished and a considerable length of time is saved
over other systems at present in use.
This form of apparatus is also useful for exposing fibres to the action of gases or
vapours as in the case of destroying cotton when mixed with woollen.

JOHN ILLINGWORTH, of Whitelee Batley in the County of York, Flock
Manufacturer IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR TREATING
"
COTTON AND WOOLLEN RAGS AND FIBRES."
The object of my Invention is the treatment of rags and other fibrous materials
after the process known as "extracting or destroying vegetable matter in rags
composed of cotton and woollen, and which is now done by immersing the said
rags in a preparation of sulphuric acid and called the "cold process."
For the purpose of carrying out my Invention I employ a cylindrical boiler
having a flue or chamber therein. The boiler is filled with water or steam for the
purpose of heating the chamber, in which is placed a perforated cylindrical cage,
caused to revolve by suitable gearing.
In order that these Improvements may be better understood, reference is given
to the accompanying sheets of Drawings wherein Fig 1 is longitudinal section,
Fig 2 cross section and Fig 3 side elevation of a machine constructed according to
my Invention. A is a cylindrical one flued boiler, B being the water or steam space,
and C the flue. Within the flue or chamber C is a perforated cage D resting upon
rollers E working in suitable brackets F attached to the sides of the chamber C.
The cage is driven at one end by shaft G from a suitable arrangement of wheels,
consisting of bevil gearing H, and spur wheels I from the main driving shaft J.
Fixed within the cage D and projecting therefrom are a series of bars or plates K
having serrated or saw teeth edges. Another set or series of serrated plates L are
employed, the teeth of which pass between the spaces formed in the plates K both
of which spiked plates are employed for willeying or shaking the fibrous
materials. The serrated plates K rotate with the cage, but the serrated plates L
are fixed, one end being attached to the bracket M whilst the other end is
connected to the pulley N which is placed loosely on the shaft G and has no
motion, the said pulley being weighted so as to counterbalance it. One end of the
Blued boiler A is made up by a plate, but the other end is provided with a door O,
having small sliding doors P therein for the purpose of admitting air into the
chamber. In communication with the chamber is an exhaust fan S driven at a
high speed by an arrangement of compound driving pulleys Q and R, for purposes
hereinafter explained; and T is another small sliding door for admitting and
regulating the supply of air to the fan. The boiler is supplied with a steam
gauge U and blow-off valve V as will be well understood that such things are
necessary for guidance and safety of the apparatus. In connection with the boiler
is an arrangement of pipes and apparatus for preparing or making a liquid
solution, composed of steain and soda, soda ash and common whitening, chalk or
lime which will destroy any acid left in the vegetable matter after extracting
process. The pipe W is placed within a jacket or outer pipe of larger diameter X,
the space or chamber b between the two pipes containing steam, which is admitted
thereto by pipe Y from any convenient source.
The alkali solution consisting of
whitening, chalk or lime is poured into the cup Z down the pipe Z¹ into the
pipe W which when full, the tap or valve Z2 is closed. When the alkali solution
is sufficiently heated by means of the steam within the chamber b the tap Z³ is
opened and steam blows at a high pressure into the alkali chamber which is forced

page_text: therefrom in combination with steam through the pipe Z' amongst the fibre in the
chamber C.
The action of the machine is as follows.—
The boiler A is supplied with steam or water until the temperature of the
chamber C reaches about 240°, when the rags or other fibre to be treated, after
the extracting or destroying process, are placed within the revolving cage D, and
after the door O of the heated chamber has been closed, the cage is set in motion
slowly, whereby the material is carried around and agitated by the serrated
plates K and L. In addition to this the exhaust fan S is set in motion, causing a
current of air, previously heated, to pass through the machine, such hot air being
obtained or brought to the fan by pipes from a steam boiler or other source
of heat.
When the material is sufficiently dried, the rotary motion of the cage is
considerably increased, whereby the machine is immediately converted into, and
answers all the purposes, of a willey or shaker, the dust or refuse fibres escaping
through the perforations a made in the cage and lodging in the bottom of
the flue.
When the fibre is sufficiently willed, the rotary motion of the cage is reduced,
and I introduce into the chamber from the alkali pipe W. the liquid solution as
herein described, which neutralizes or destroys any acid left in the animal matter
after the extracting process.
When the acids in the fibre have been destroyed by the introduction of the
alkali just mentioned, the cage continues to revolve, and in addition thereto, the
exhaust fan S is again set in motion, and a suitable quantity of hot air again
brought through the chamber as before explained, whereby the condensed steam
within the chamber, arising from the dried fibre is removed, allowing the fibre to
be thoroughly dried, after which cold air is admitted instead of hot air, whereby
the fibre is dried, softened and made ready for use.
By the employment of this form and construction of apparatus and the method
of treating rags as herein described, the various processes are accomplished and a
considerable length of time saved over other systems at present in use.
This form of apparatus is also useful for exposing fibres to the nation of gases or
vapours-as-in-the-euse-of-destroying cotton-when-mixed with woollen.
Having thus described my Invention and the manner in which the same has to
be performed, I would have it understood that I do not confine myself to the exact
details herein shewn and described as some of them may be varied without
departing from the escential [sic] features thereof but what I desire to claim is.
Firstly. The employment of a rotary cage working within the heated flue or
chamber of a steam boiler, for the purposes of drying fibrous materials substantially
as herein shewn and described.
Secondly. In combination with such machinery and for purposes herein
described, I claim the application of an alkali solution composed of whitening,
chalk or lime combined with steam for neutralizing the acids left in the animal
fibre after the extracting process.
Thirdly The employment of an exhaust fan working in combination with the
drying machine herein shown and described.
In witness whereof I the said John Illingworth have hereunto set my hand
and seal this first day of December in the year of our Lord one thousand eight
hundred and eighty three.

"
The object of my Invention is the treatment of rags and other fibrous materials
after the process known as extracting or destroying vegetable matter in rags
composed of cotton and woollen, and which is now done by immersing the said
rags in a preparation of sulphuric acid and called the "cold process."
For the purpose of carrying out my Invention I employ a cylindrical boiler
having a flue or chamber therein. The boiler is filled with water or steam for the
purpose of heating the chamber, in which is placed a perforated cylindrical cage,
caused to revolve by suitable gearing.
In order that these Improvements may be better understood, reference is given
to the accompanying sheets of Drawings wherein Fig 1 is longitudinal section,
Fig 2 cross section and Fig 3 side elevation of a machine constructed according to
my Invention. A is a clyindrical one flued boiler, B being the water or steam space,
and C the flue. Within the flue or chamber C is a perforated cage D resting upon
rollers E working in suitable brackets F attached to the sides of the chamber C.
The cage is driven at one end by shaft G from a suitable arrangement of wheels,
consisting of bevil gearing H, and spur wheels I from the main driving shaft J.
Fixed within the cage D and projecting therefrom are a series of bars or plates K
having serrated or saw teeth edges. Another set or series of serrated plates L are
employed, the teeth of which pass between the spaces formed in the plates K both
of which spiked plates are employed for willeying or shaking the fibrous
materials. The serrated plates K rotate with the cage, but the serrated plates L
are fixed, one end being attached to the bracket M whilst the other end is
connected to the pulley N which is placed loosely on the shaft G and has no
motion, the said pulley being weighted so as to counterbalance it. One end of the
flued boiler A is made up by a plate, but the other end is provided with a door O,
having small sliding doors P therein for the purpose of admitting air into the
chamber. In communication with the chamber is an exhaust fan S driven at a
high speed by an arrangement of compound driving pulleys Q and R, for purposes
hereinafter explained; and T is another small sliding door for admitting and
regulating the supply of air to the fan. The boiler is supplied with a steam
gauge U and blow-off valve V as will be well understood that such things are
necessary for guidance and safety of the apparatus. In connection with the boiler
is an arrangement of pipes and apparatus for preparing or making a liquid
solution, composed of steam and soda, soda ash and common whitening, chalk or
lime which will destroy any acid left in the vegetable matter after extracting
process. The pipe W is placed within a jacket or outer pipe of larger diameter X,
the space or chamber 6 between the two pipes containing steam, which is admitted
thereto by pipe Y from any convenient source. The alkali solution consisting of
whitening, chalk or lime is poured into the cup Z down the pipe Z¹ into the
pipe W which when full, the tap or valve Z' is closed. When the alkali solution
is sufficiently heated by means of the steam within the chamber b the tap Z³ is
opened and steam blows at a high pressure into the alkali chamber which is forced
therefrom in combination with steam through the pipe Z* amongst the fibre in the
chamber C.

The action of the machine is as follows.—
hailan A Iliad with atoom on water until the temperature of the

page_text: chamber C reaches about 240°, when the rags or other fibre to be treated, after
the extracting or destroying process, are placed within the revolving cage D, and
after the door O of the heated chamber has been closed, the cage is set in motion
slowly, whereby the material is carried around and agitated by the serrated
plates K and L. In addition to this the exhaust fan S is set in motion, causing a
current of air, previously heated, to pass through the machine, such hot air being
obtained or brought to the fan by pipes from a steam boiler or other source
of heat.
When the material is sufficiently dried, the rotary motion of the cage is
considerably increased, whereby the machine is immediately converted into, and
answers all the purposes, of a willey or shaker, the dust or refuse fibres escaping
through the perforations a made in the cage and lodging in the bottom of
the flue.
When the fibre is sufficiently willed, the rotary motion of the cage is reduced,
and I introduce into the chamber from the alkali pipe W the liquid solution as
herein described, which neutralizes or destroys any acid left in the animal matter
after the extracting process.
When the acids in the fibre have been destroyed by the introduction of the
alkali just mentioned, the cage continues to revolve, and in addition thereto, the
exhaust fan S is again set in motion, and a suitable quantity of hot air again
brought through the chamber as before explained, whereby the condensed steam
within the chamber, arising from the dried fibre is removed, allowing the fibre to
be thoroughly dried, after which cold air is admitted instead of hot air, whereby
the fibre is dried, softened and made ready for use.

of treating rags as herein described, the various processes are accomplished and a
considerable length of time saved over other systems at present in use.
This form of apparatus is also useful for exposing fibres to the action of gases or
