MACHINERY FOR DECORTICATING THE TEXTILE OR FIBROUS SUBSTANCES."
The object of our Invention is to disaggregate the stalks of china grass in its
green state, and to remove the fibre which is confined in the bark. The improved
machinery is equally applicable to the treatment of flax, hemp, and other textile
fabrics. On the accompanying Drawing,
Figure 1 represents a plan of the machine; Figure 2, elevation, and Figure 3,
detailed view of part of the same. Like letters of reference indicate corresponding
parts in all the Figures. A, represents the frame of the machine; B and C, rotary
cylinders armed longitudinally with blunt blades or knives, the intervals between
which are provided with wood or other soft and resistant material. When in
motion each blade of one cylinder corresponds with the middle of an interval on
the other cylinder, and vice versa, as in Figure 3; B', toothed wheel on the axis of
the cylinder B, gearing with the toothed wheel G¹ on the axis of the cylinder C;
E, E, adjustable screws with their cramps for drawing together or separating tho
cylinders B and C; H, driving pulley; H', pulley on the axis of the pulley H
giving movement to the pulley E by the belt O, or this movement may bo
transmitted by chain or by gearing; F¹, endless screw or worm on the axis of the
pulley F, gearing with its wheel G which gives motion to the grooved fly wheel D;
D, circular grooved plate with its cord J feeding the cleaning cylinders B and C,
and receiving into its groove the cord J which is maintained and tightened by the
grooved pulley L by means of its apparatus L'; M, india rubber pad on the stem
of the apparatus L' serving as a spring to compensate for the inequalities more or
less of the stalks of china grass furnished to the machine. The grooved fly wheel D
with its cord J and its tightening apparatus L and L' constitute a novel circular

page_text: holder or continuous pincer; K, roller crusher which is supported by the apparatus K¹
turning on its axis fixed to the piece A¹ of the frame A. By means of its lever K
the roller crusher is more or less brought towards the plate D, and crushes the feet
of the stalks introduced at I between the cord J and the circular plate D;
N, revolving guide holding the fibres close to D, and preventing them from
turning aside until at the end of the cylinders B and C; D, hooks placed on the
circumference of the grooved fly wheel D for suspending the fibres, the feet of
which it is desired to clean; P, table on which are brought over the tops of the
stalks, whereof the feet are engaged at the point I between the cord J and the fly
wheel D.
R, guide placed below the fly wheel D for effecting the introduction between the
cylinders B and C of the feet of the stalks-which-are-returned for being, cleaned.
All the parts of the frame above the machine can be placed below the cylinders B
and C and fly wheel D. The pulley of cominand H gives motion to the two
cylinders B and C. The pulley H¹ by the belt O transmits the movement of the
pulley F, causing to turn by means of the endless screw or worm F' and its gear
wheel a the circular holder D with its cord J. The arrows indicate the direction
of the movement of the pieces.
Each packet of china grass of 5 to 20 stalks, according to their size, is introduced
by its large end or feet of the stalks between the cord J and the fly wheel D at
the point I, and being immediately seized the heads or-tops-of-the-stalks.are brought
over on the table P.
The rotary movement of the plate D introduces the stalks by degrees between
the cleaners or cylinders B and C, and these bruising and peeling the stalks
disorganise them, and clear their fibres from leaves, wood, bark, and other matters.
The stalks having followed the rotary movement of the holder D are brought back
and discharged at the point I', being delivered in the form of fibres suspended by
the feet engaged between the cord and the fly wheel. When it is wished to clean
the ends or feet, that is to say, the part of the stalks which being engaged between
the cord J and the fly wheel D has not been able to receive the action of the
cylinders, the workman at I' makes a turn with his small packets of fibres round
about one of the hooks D' placing on the plate D the cleaned fibre, and leaving the
feet to hang below the plate D about 0-10 centimetres. This fibre is retaken by
the cord Jencountering the guide R which introduces the feet between the
cylinders, where they are worked and go out again cleaned at the point I'. When
the operator has water readily at hand, and principally for certain kinds of grasses
charged with gums or resins, it would be convenient to arrange a small pipe which
would allow a light stream of water to escape between the two cylinders with the
effect of carrying off the greater part of the gum or resin.

on the axis of the pulley H giving movement to the pulley E by the belt O, or
this movement may be transmitted by band, chain, or by gearing; F¹, endless
screw or worm on the axis of the pulley F gearing with its wheel G gives motion
to the grooved plate or fly wheel D, which feeds the cleaning cylinders B and C,
and receives into its groove the cord J, which is maintained and tightened by the
grooved pulley L by means of its apparatus L'; M, india rubber pad on the stem
of the apparatus L', serving as a spring to compensate for the inequalities more or
less of the stalks of china grass furnished to the machine. The grooved plate
or fly wheel D with its cord J and its tightening apparatus L and L' constitute a
novel circular holder or continuous pincer; K, roller crusher which is supported
by the apparatus K¹ turning on its axis fixed to the piece A¹ of the frame A. By
means of its lever K' tho roller crusher is more or less brought towards the plate D,
and crushes the feet of the stalks introduced between the cord J and the circular
plate D; N, revolving guide holding the fibres close to D, and preventing them
from turning aside until at the end of the cylinders B and C; D', books placed on
the circumference of the grooved plate or By wheel D for suspending the fibres,
the feet of which it is desired to clean; P, table on which are brought over the tops
of the stalks whereof the feet are engaged between the cord J and the fly wheel D;
K, guide placed below the fly wheel D for effecting the introduction between the
cylinders B and C of the feet of the stalks which are returned for being cleaned.
If desired all the parts of the frame above the machine may be placed below the
cylinders B and C and fly wheel D. The pulley of command H gives motion to
the two cylinders B and C. The pulley H by the belt O transmits the movement
to the pulley F, causing by means of the endless screw or worm F' and its gear
wheel Ġ the circular holder D with its cord J to revolve. The arrows indicate the
direction of the movement of the pieces.
OPERATION OF THE MACHINE.-Each packet of china grass of 5 to 20 stalks,
according to their size, is introduced by its large end or foot of the stalks between
the cord J and the fly wheel D at the point I, and being immediately seized the
heads or tops of the stalks are brought over on the table P. The rotary movement
of the plate D introduces the stalks by degrees between the cleaners or cylinders B
and C, and these bruising and peeling the stalks disorganise them, and clear their
fibres from leaves, wood, bark, and other matters. The stalks having followed

page_text: the rotary movement of the holders D are brought back and discharged at the
point I' being delivered in the form of fibres suspended by the feet engaged between
the cords and the fly wheel. When it is wished to clean the ends or feet, that is
to say, the part of the stalks which being engaged between the cord J and the fly
wheel D have not been able to receive the action of the cylinders, the workman
at I¹ makes a turn with his small packets of fibres round about one of the hooks D'
placing on the plate D the cleaned fibre, and leaving the feet to hang below the
plate D about 0-10 centimetres. This fibro is retaken by the cord J encountering
the guide R which introduces the feet between the cylinders where they are
worked, and go out again cleaned at the point 1. When the operator has water
readily at hand, and principally for certain kinds of grasses charged with gums or
resins, it would be convenient to arrange a small pipe which would allow a light
stream of water to escapo between tho two cylinders with the effect-of-carrying off-
the greater part of the gum or resin.
Having now described the nature of my Invention I would observe in conclusion
that what is claim is,―
1. The construction and arrangement of the grooved circular plate or fly
wheel D with its cord J and tightening apparatus L. L', substantially as and
for the purpose hereinbefore described and illustrated by the accompanying
Drawing.
2. The construction and arrangement of cylinders B and C with their spaces
between the blades or knives furnished with a soft and resistant material,
substantially as and for the purpose herein before described and illustrated by the
accompanying Drawing.
3. The combination and arrangement of the circular carrier D-with-the-cylinders-B-
and C, and other parts of the machine, as and for the purpose herein before
described and illustrated by the accompanying Drawing.
In witness whereof, I, the said Eugéne Joseph Couty, have hereunto set my
hand and seal, this 5th day of October, in the year of our Lord One
thousand eight hundred and eighty.
