Improvements in and relating to the Fleece Delivering and Feeding
Apparatus of Carding Engines.
I, CARL OSWALD LIEBSCHER, of Gera, in the Principality of Reuss, German
Empire, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The present invention relates to an improvement in cards by means of which
the composition as well as the fibre direction of the fleece to be removed from
one card to the other can be varied. With certain material it has been necessary
to feed the fleece, which was fed up to now only in longitudinal or transverse
direction, in combined direction, in order to get a better mixture, and a com-
pletely uniform fleece.
To prevent any misunderstanding as to the expressions "feeding with trans-
verse and feeding with longitudinal fibres" I beg to state that in the feeding
with longitudinal fibres the Heece or the fibres removed from the doffer are thrown
in a vertical or nearly vertical direction to the working parts of the cards, so that
the fibres lie in the longitudinal direction of the feeding band or feeding table.
When feeding with transverse fibres the fleece is placed upon the feeding table
in such a manner, that the fibres are lying transversely to the direction of motion
and consequently parallel to the working parts of the card.
Evidently the combinations are not limited to the longitudinal or transverse
feeding but also any inclined sheets can be used whereby either one sheet is
lying longitudinally and the other transversely, or both are diagonal the one
to the other.
In order to make my invention more clear, I refer to the accompanying draw-
ing, in which an example of my feeding device is represented and in which
similar letters refer to similar parts throughout the different figures.
Figure 1 represents an elevation of the removing device.
Figure 2 is an elevation of the feeding-device,
Figures 3 & 4 are respective plan views of Figs, 1 & 2,
Figure 5 is a detail elevation of the card and removing device;
Figure 6 is a uetail elevation view of the cutting-device
Figure 7 is an enlarged elevation of the blade when stretched and bent.
In the feeding of the fleece two slivers F F are separated either on the card
itself or by a blade, and then superposed in different fibre-directions. The dis-
position is made in such a way, that the one sheet of the fleece is removed in
longitudinal and the other in transverse fibre direction. The sliver coming from
the left part of the card P is conducted through a slotted band P¹ situated diago-
nally to the card and to the feeding-band. By means of the slotted band Pl it
is folded together whereby its thickness is increased and then placed in this
thickness upon the feeding table, in a reversed direction, owing to the slotted band.
The placing upon the feeding-table is effected by means of the rollers W*.
Naturally the fibres are situated with their longitudinal directions in such a

page_text: manner that they run parallel to the direction of motion. The fleece by the
turn has only altered its direction of motion.
Upon this fleece-sliver F a second fleece-sliver coming from the right side
of the card is placed, which fleece also is folded up and its thickness increased
by means of the roller W, as will be seen from the annexed drawing. This
fleece-sliver, the longitudinal fibre direction of which is lying vertically, is cut
by a blade into pieces of a length equal to the breadth of the fleece-sliver F
lying underneath. The upper fleece-fibre with its longitudinal direction is
lying transversely to the underneath fleece as by means of the blade it is con-
ducted from its vertical position into a horizontal position and folded up.
The same process can be employed when several cards have to work with one
doffing cylinder. When turning the rollers WW2 (Figures 1 & 3) the fleece
can be placed diagonally át a certain angle. The blade M (Figures 6 & 7) used
for cutting the fleece, when returning, must pass the new delivered fleece F".
For this purpose the blade M, Figure 7, comprises several parts mounted together
in such a manner, that the upper part of the blade can turn around the pivot C.
In proximity of the pivot C is fixed a cam 1; the blade is stretched by a spring Z.
This cam I fixed to the upper part of the blade, when the blade is in the straight-
ened position, bears against a stop a fixed to the lower part of the blade. The
blade is actuated by an eccentric E driven from the shaft of the card, Figure 6,
which eccentric is in connection with the rod V and the tooth wheel sectors S.
By the revolution of the eccentric E the wheels $ (one of which is rigidly con-
nected to the blade M) are caused to revolve, so that the blade will be placed
horizontally. When the blade is withdrawn, the elastic pin Q pushes against
the upper surface of the slide G and is obliged to adopt the way of the slide.
Thereby the knife is bent, as shown in Figure 7, in dotted lines, and the hanging
fleece-sliver can pass. As soon as the pin Q has reached the end of the slide &
the spring which is attached to the upper as well as to the lower part of the
blade comes into action and returns the blade to its original stretched position
when the cam D bears against the stop a.
Evidently it is not necessary to bend the blade as it can easily be constructed in
such a manner as to pass the fleece-sliver by sliding together. The fleece may also
be placed continually in the usual way by means of oscillating rollers whereby
the band shown in Figure 4 is formed, characterized by the zigzag-lines formed
on the one hand by the double motion of the table and on the other hand by the
double motion of the rollers. The fibres are lying transversely or nearly
transversely.
As it will be seen from Figures 1 & 2 the sliver B is conducted from the
table T to the feeding bands TT³ placed parallel one to the other. From the
latter it is passed between the rollers MM" and conducted to the table T¹
forming part of the card where it is placed in sheets (Figure 4). The folding
of the sliver is effected by the combined feeding and oscillating motions of the
bands TT3. The side-walls supporting the bearings of the rollers (Figures 2
& 4) which run on rails, are at their upper ends pivotable around the pin b;
the device embracing the table T pivots round the pin f. The oscillating motion
of the tables T2 T3 as well as the motion of the rollers M* and M connected
with the aforesaid tables is effected in the following manner:
The spindle of the guide-rollers (Figure 4) is rigidly connected with a chain k
running over chain-wheels KK", while the latter get their motion from the
bevel-wheels K K¹ K2 and the spur-wheels J J. The wheels K and K² are
mounted upon a sliding sleeve operated by a lever U pivoted at O. When the
pusher N strikes against the lever U, the wheel K2 is thrown into gear with the
wheel K and when the pusher N' strikes against the lever U¹ pivoted at ()
the lever is operated by means of the rod %, throwing the wheel K into gear
with the wheel K¹ and thereby reversing the direction of motion of the wheels J.J¹
the chain-wheels K* K* and the chain k. To the chain k are attached rollers r
running on rails s, whereby a horizontal motion is given to the tables T2 and T³.

page_text: The rapid reversing of motion of the wheel K¹ effects the oscillating motion
of the tables T2 T3 and the placing in sheets of the fleece B on the table T
It has already been mentioned that the direction of one fleece sliver can be
varied by turning the fixed rollers W W (Figures 1-3) around a certain angle.
The same can be done with the second fleece sliver by turning the roller W*. In
this way different combinations of fleece slivers are rendered possible. Naturally
the number of the possible combinations can be increased with three or more
fleece-sheets.
It has to be said that this feeding device can be employed for several cards,
the fleece slivers of which have to be superposed in different fibre direction. For
the sake of clearness only one card has been taken as example.
No special weight is laid upon the continuation of the treatment of the slivers,
but only upon the different combinations of the fleece-slivers and the use of the
interchangeable feeding-devices.

Improvements in and relating to the Fleece Delivering and Feeding
Apparatus of Carding Engines.
I, CARL OSWALD LIEBSCHER, of Gera, in the Principality of Reuss, German
Empire, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The present invention relates to an improvement in cards by means of which
the composition as well as the fibre direction of the fleece to be removed from
one card to the other can be varied. With certain material it has been necessary
to deliver the fleece, which was delivered up to now only in longitudinal or trans-
verse direction, in combined direction, in order to get a better mixture, and a
completely uniform fleece.
To prevent any misunderstanding as to the expressions delivering with trans-
verse and delivering with longitudinal fibres "I beg to state that in the delivering
with longitudinal fibres the fleece or the fibres removed from the doffer are
thrown in a vertical or nearly vertical direction to the working parts of the cards,
so that the fibres lie in the longitudinal direction of the delivery apron. When
delivering with transverse fibres, the fleece is placed upon the delivery apron
in such a manner that the fibres are lying transversely to the direction of motion
and consequently parallel to the working parts of the card.
Evidently the combinations are not limited to the longitudinal or transverse
delivery but also any inclined sheets can be used whereby either one sheet is
lying longitudinally and the other transversely or both are diagonal the one to
the other.
In order to make my invention more clear, I refer to the drawing filed with
the Provisional Application, in which an example of my delivery device is repre-
sented and in which similar letters refer to similar parts throughout the different
figures.
Figure 1 represents an elevation of the removing device,
Figure 2 is an elevation of the delivery device,

page_text: Figure 5 is a detail elevation of the card and removing device;
Figure 6 is a detail elevation of the cutting device,
Figure 7 is an enlarged elevation of the blade when stretched and bent.
In the delivery of the fleece two slivers F F¹ are separated either on the card
itself or by a blade, and then superposed in different fibre-direction. The dis-
position is made in such a way, that the one sheet of the fleece is removed in
longitudinal and the other in transverse fibre direction. The sliver coming from
the left part of the card P is conducted through a slotted band P₁ situated diago-
nally to the card and to the delivery apron. By means of the slotted band P¹ the
sliver is folded together whereby its thickness is increased and then placed in
this thickness upon the delivery apron in a reversed direction, owing to the slot-
ted band.
The placing upon the delivery apron is effected by means of the rollers W*.
Naturally the fibres are situated with their longitudinal directions in such a
manner that they run parallel to the direction of motion, which the fleece by
this turn has only altered.
Upon this fleece-sliver a second fleece-sliver F¹ coming from the right side
of the card is placed, which fleece also is folded up and its thickness increased
by means of the roller W, as will be seen from the drawing. This fleece-sliver,
the longitudinal fibre direction of which is lying vertically, is cut by a blade
into pieces of a length equal to the breadth of the fleece-sliver Flying under-
neath. The upper fleece fibre is laid transversely on to the underneath fleece,
as, by means of the blade, it is conducted from its vertical position into a hori-
zontal position.
The process can be employed in the same manner when several cards and one
doffing cylinder are in action. By turning the rollers W (Figures 1 & 3) the
fleece can be placed by the blade M. diagonally at a certain angle. The blade M
(Figures 6 & 7) used for cutting the fleece, when returning, must pass beneath
the new delivered fleece F. For this purpose the blade M, Figure 7, comprises
several parts mounted together in such a manner, that the upper part of the
blade can turn around the pivot C. In proximity of the pivot C is fixed a cam D);
the blade is stretched by a spring Z. This cam 1) fixed to the upper part of the
blade, when the blade is in the straightened position bears against a stop
fixed to the lower part of the blade. The blade is actuated by an eccentric E
driven from the shaft of the card, Fig. 6, which eccentric is in connection with
the rod and the tooth wheel sectors S. By the revolution of the eccentric E
the wheels S (the one of which is rigidly connected to the blade M) are caused
to revolve, so that the blade will be placed horizontally. When the blade is
withdrawn, the pin Q rendered elastic by means of a spiral spring pushes against
the upper surface of the slide G and is obliged to adopt the way of the slide.
Thereby the knife is bent, as shown in Figure 7 in dotted lines, and the hanging
fleece-sliver can pass. As soon as the pin Q has reached the end of the slide G
the spring which is attached to the upper as well as to the lower part of the
blade comes into action and returns the blade to its original straightened position
when the cam D bears against the stop a.
Evidently it is not necessary to bend the blade as it can easily be constructed
in such a manner as to pass the fleece-sliver by sliding together. The fleece may
also be placed continuously in the usual way by means of oscillating rollers
whereby the band shown in Figure 4 is formed, characterised by the zigzag-
lines and formed on the one hand by the motion of the apron and on the other
hand by the double motion of the rollers. In this band the particular fibres are
lying transversely or nearly transversely.
As will be seen from Figures 1 & 2 the sliver B is conducted from the apron T
to the aprons T T placed parallel one to the other. From the latter it is thrown
between the rollers M* M* and conducted upon the apron T₁ forming part of
the card where it is placed in sheets (Figure 4). This folding of the sliver is
effected by the fact, that the aprons T and T3 have besides their rotative motion

page_text: also an oscillating motion. The side-walls supporting the axles of the rollers r
(Figures 3 & 4) running on rails, are on their upper parts pivotable around the
pin b; a part of the apron T is carried by a frame pivoted round the pin f. The
oscillating motion of the aprons T2 T3 as well as the motion of the rollers M* M*
connected with the foresaid aprons is effected by the fact that the spindle of
the guide-rollers r (Figure 4) is rigidly connected with a chain running over
chain-wheels KK" while the latter get their motion from the bevel-wheels K
K K2 and the spur wheels J J. The wheels K and K are in driving connection
and movable upon a slide-piece such as to turn the lever U round the point 0
when the pusher N pushes against it. At the same time this motion is communi-
cated to the lever U₁ pivoting round 01 by means of the rod Z.
When the lever U turns, the wheel K being in connection with the back-part of
the lever U gets out of engagement and the wheel K² engages with K': thereby
a reversing of the direction of motion of the wheels J J the chain-wheels K* K*,
and the chain K is effected. To the chain k are attached rollers running on
rails whereby a horizontal motion is given to the aprons T2 T3. On the opposite
side, the reversing is effected by means of the lever and the pin N¹, and again
the direction of motion is changed. The rapid reversals effect the oscillating
motion of the aprons T2 T3 and the placing in sheets of the fleece B on the apron T¹.
It has already been mentioned that the direction of one fleece sliver can be
varied by turning the fixed rollers W2 W2 (Figures 1-3) around a certain angle.
In this way different combinations of fleece slivers are rendered possible.
Naturally the number of the possible combinations can be increased with three
or more fleece-sheets.
In the drawing the fleece slivers are removed from one doffer only, evidently
they might be removed from several doffers and superposed crosswise or diagonal.
The continuation of the treatment of the slivers, does not form a part of my
invention, but only the different combinations of the fleece-slivers and the use of
the delivery devices adapted to be arranged in different inclinations.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In fleece-delivering of cards, an arrangement for feeding the fleece with the
fibres arranged simultaneously in different directions, substantially as described.
2. In fleece-delivering, the combination with means for removing the fleece
in two or more portions or slivers from the doffer of means for superposing the
slivers in different fibre-directions, substantially as described.
3. The improved fleece-delivery of cards, substantially as described.
