HERBERT JOHN HADDAN, of Kensington, Middlesex, IMPROVEMENTS IN
FLEECE-DIVIDING ATTACHMENTS TO CARDING MACHINES," a communication to me
from abroad by J. S. Bolette, of Massau-Cornesse, near Pepinster, Belgium,
This invention relates to fleece dividing apparatus for carding machines.
The improvements consist in dividing the fleece when it leaves the carding
machine, into slivers on the rubber of the carding machine itself by means of
endless steel-bands passing over rollers on both sides of the dividing-cylinders and
arranged in such a manner as to pass twice between the dividing cylinders, so that
both parts nearly come in contact with each other at the point where the division
takes place.
Another modification consists in arranging the steel bands so as to pass to and
fro between the dividing cylinders, in which case the bands are fixed to grooved
rollers either with one end only or with both ends and slowly drawn forward and
backward by the alternating motion of these rollers.
If only one end is fixed, the other end is held against the dividing rollers by a
roller.
A further improvement consists in applying to the dividing cylinders a travelling
brush for the purpose of cleaning the steel bands and the cylinders, the said brush
being preferably pivoted on a shaft and caused to travel from right to left and
vice-versa in one of the angles formed by the dividing cylinders.
The invention further consists in the application of a movable plate or blade
pivoted on a shaft and serving to introduce the fleeco between the dividing
cylinders.

HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
FLEECE DIVIDING ATTACHMENTS TO CARDING MACHINES," a communication to me
from abroad by J. S. Bolette, of Massau-Cornesse, near Pepinster, Belgium,
The improvements consist:
1. In causing the dividing steel blades of the apparatus invented by Bede & Cle
and patented in England on the 10th of March 1873 to travel in the direction of
their length.
2. In the use of two special sleeves for keeping the travelling blades close
against the dividing blades.
8. In the use of a stretched steel blade mounted on oscillating levers for
introducing the sheet of wool into the divider.
The steel blades J J¹, are fixed with one of their ends to two horizontal
rollers E E', extending along the upper and lower dividing sleeves, pass between
them and cross each other close behind the contact point of the latter-A toothed
rack G moving slowly up and down catches the pinions F F¹, keyed on the ends of
the axle of the rollers E E¹, thereby giving to the latter a rotary motion forward
and backward, actuating at the same time the dividing blades in the way shown.
The lower roller pushes one row of blades, while the upper roller is attracting the
other row.
The motion of the toothed-rack G is effected by an eccentric H provided with a
groove, into which projects a roller g, fixed at the end of the rack.
The eccentric H has on its axle a pinion O and is set in rotation by an endless
screw V fixed at one end of the shaft of the lower moveable sleeve L. It
communicates its motion to the pinion O by means of a pinion p and an endless
screw V fixed on a shaft secured to the bracket.
These pieces of mechanism are calculated so that the motion of the blades as
compared with that of the slivers passing between the said blades and with the
friction sleeve is slow enough not to be detrimental to the passages of the said
slivers. This slow forward and backward motion, communicated to the blades,
has for its object to increase their duration by causing them to wear slowly and
uniformly on a greater length of the blades and to clean them continually from
the waste and coom which usually accumulate in case of fixed blades.
The above mentioned motion of the blades may be obtained by attaching them
to bars or rails and giving the latter an up and down motion, or the said blades
may be actuated by means of counterpoises.
Two small rings & d' serve to hold the blades on the rollers in order to prevent
their bending by elasticity, so as to escape from the small sleeves.
A roller R is in contact with the inner surface of the dividing sleeve in order to
increase the resistance of the latter at the point where the friction of the sleeve occurs.
A roller S coated with grease and revolving with the rubber M serves to collect
the broken threads falling from the top of the apparatus. The small special
sleeves serving to hold the dividing blades applied at all points of their travel to
the friction sleeve are sufficiently shown in the drawing. It is therefore only
necessary to remark that they are set in motion by the other sleeves by means of
tooth wheels.
The mechanism for introducing the fleece between the sleeves, is composed of
two levers D' placed at each side of the divider which oscillates on fixed pivots
attached by slotted brackets to the frame of the apparatus.

page_text: These levers carry at their extremity the two ends of a steel blade D stretched
7 a screw-spindle e which connects the two levers. When the fleece C is detached
om the combing machine by the comb B, it is allowed to fall against the blade D
ee dotted line C¹), and in proportion as the fleece leaves the combing machine,
e lever D' and the blade D are lifted by hand (see the different positions of the
tter indicated by dotted lines C to C) until the blade delivers the fleece between
e sleeves at the point where the dividing blades cross each other.
Owing to the mechanism described one workman is sufficient in starting the
achine for introducing the fleece at once along its whole width between the
viding sleeves which result cannot he obtained in seizing the fleece by hand, as
as hitherto been done with the aid of four persons.
What I claim is:
A fleece dividing attachment for carding machines having dividing blades which
cross each other between the dividing sleeves and receive an independent to
and fro motion in the direction of their length with a speed different from
the circumferential speed of the dividing sleeves substantially as described.
The mechanism consisting of the combination with a rack G and the pinions F F¹
keyed on the shaft of the blade rollers, of an eccentric H driven by the
pinion O, the worm V' with worm wheel p and the worm V keyed on the
shaft of the rubber L', substantially as described.
The combination of the dividing blades and dividing sleeves with special
sleeves N N¹ for holding the said blades against the said sleeves, substantially
as described.
The combination of the dividing sleeves L L with a steel blade for introducing
the fleece between the dividing sleeves, substantially as described.
The combination of the dividing sleeves L L' with a steel blade attached to and
stretched by oscillating levers, substantially as described.
n witness whereof I the said Herbert John Haddan have hereunto set my
and and seal this fourth day of October A.D. 1883.
