Improvements in, or connected with Carding Engines.
We, GUSTAV JOSEPHY, of Bielitz, Austrian Silesia, and EDUARD SCHÖNEICH, of
Kupawna, near Moscow, in the Russian Empire, Spinning Mill Proprietor and Spinning
Mill Manager respectively, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement in carding engines its object being to
effect in a ready and efficient manner the removal of coarse inelastic and hard
portions or hairs or the like which we will refer to as hairs from fine fibrous material.
It is well known that such hairs occur in almost every kind of wool but more
particularly in "
goats down," in camelshair, mohair, alpaca wool, and the like, and
as these hairs very materially impede the treatment of the mass of fibres to be spun,
their removable is most desirable.
This invention mainly consists of the combination with a carding engine of an
attachment wherein an intermittently moving knife edge is brought as near as may
be necessary to the clothing or card cloth of the drum.
The arrangement is interposed between the doffer and the device which serves to
raise the fibres out of the card-cloth of the drum, so that they may be readily
removed by the said doffer, so that the said knife acts on the mass of fibre which
lies loose upon the surface of the drum at that part.
The knife employed in accordance with our invention is adjusted as accurately as
the nature of the material to be cleansed may require, by any suitable means, such
as screws for instance. The fine supple fibres of the mass do not lose their proper
direction on account of their impinging on the said knife edge but pass through
underneath the same, and are thus in the usual way conveyed to the doffer; whereas
the coarse hair cannot withstand the impact against the knife edge but fall upon the
knife surface and are delivered on to a table or bench. In order to prevent the
removed hairs from collecting in the vicinity of the knife, means are provided to
blow said hairs towards a receptacle that may adjoin the said bench or table.
To keep the knife constantly free from any material that might collect thereon,
the knife has a reciprocating movement imparted to it, being adapted to slide in
suitable supports, and brushes are arranged to sweep the knife on both sides of the
card.
Instead of a knife as mentioned above, revolving knives may be employed if
desired. These revolving knives turn at brief intervals so as to bring intermittently
a new knife close to the drum in the manner and for the purpose herein before
described; where there are for inst. 2, 3, 4, 5, or 6 knives, one half, one third, one
quarter, one fifth or one sixth of a revolution upon each occasion is performed, and
so on according to the number of knives.
The hairs eliminated are dropped upon a suitable delivering table.

We, GUSTAV JOSEPHY, of Bielitz, Austrian Silesia, Spinning Mill Proprietor, and
EDUARD SCHÖNEICH, of Kupawna, near Moscow, in the Russian Empire, Spinning Mill
Manager, do hereby declare the nature of this 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 relates to an improvement in carding engines its object being to
effect in a ready and efficient manner the removal of coarse inelastic and hard portions
or hairs or the like which we will refer to as hairs from fine fibrous material. It is
well known that such hairs occur in almost every kind of wool but more particularly
in << goats down," in camelshair, mohair, alpaca wool, and the like; and as these
hairs very materially impede the treatment of the mass of fibres to be spun, their
removable is most desirable.
This invention mainly consists of the combination with a carding engine of an
attachment wherein an intermittently moving knife edge is brought as near as may
be necessary to the clothing or card cloth of the drum.
The arrangement is interposed between the doffer and the device which serves to
raise the fibres out of the card cloth of the drum, so that they may be readily
removed by the said doffer, so that the said knife acts on the mass of fibre which lies
loose upon the surface of the drum at that part.
In the accompanying drawings
Figure 1 is a cross section, and Figure 2 is a sectional side elevation of a carding
engine fitted with an arrangement according to this invention.
Figure 3 is a corresponding rear view, and
Figure 4 a cross section of a modified form of the arrangement.
Figure 5 illustrates an arrangement for intermittently rotating the cutters shewn
in Fig. 4.
The knife employed in accordance with this invention for removing the hairs above
referred to, is adjusted, as accurately as the nature of the material to be cleansed may
require, by means of the screw 2. The fine supple fibres of the mass do not lose
their proper direction on account of their impinging on the said knife edge, but pass
through, underneath the same, and are thus in the usual way conveyed to the doffer;
whereas the coarse hair cannot withstand the impact against the knife-edge, but fall
upon the knife-surface and are thus delivered on to the table or bench 3. To prevent
the removed hairs from collecting in the vicinity of the knife 1, the device which
raises the fibres is so adjusted that it blows them towards the receptacle 4 adjoining
the said bench or table 3.
In order to keep the knife I constantly free from any material that might collect
thereon, the knife-which for this purpose is made twice as wide as the card-has a
reciprocating or backward and forward movement imparted to it by means of a rack 7,
on the knife, engaged by a toothed wheel or pinion 8 rotated by means of gearing 9
from any suitable part of the machine the direction of rotation and consequently of
the traverse of the knife 1 being reversed by means of a reversing clutch as shewn
in Figure 3, the said knife being adapted to slide in its supports 5. The knife is
constantly swept on both sides of the card by brushes 6 maintained in rapid rotary
motion from any suitable part of the machine as shewn for instance in Figure 2.
Instead of a knife such as is shewn in the examples illustrated in Figures 1, 2
and 3, revolving knives as shewn in Figure 4, may be employed if desired. In this
case also the knives 1 should be arranged close to the drum and the shaking or
knocking off of the hairs takes place in the manner herein before described.
The said revolving knives operate on the fibrous material in succession at each

page_text: quarter of a revolution, or where there are 2, 3, 5 or 6 knives, at one half, one third,
one fifth or one sixth of a revolution and so on according to the number of knives.
The intermittent motions of the cutters 1 are produced as shewn in Fig. 5 by a
pawl 5 secured to the lever 4 and in gear with a ratchet wheel 2 on the shaft of the
rotating cutters. A swinging motion of the lever 4 is produced by the rod 7 which
is raised against the counteracting power of a spring 11 by a stud 9 projecting from
a disc 8 and acting on a tappet 10 on the rod 7. The extent of the downstroke or
movement of the rod 7 by the spring 11 is limited by a collar 12 thereon coming
into contact with a stop 13. A roller carried by a lever 14 engages in recesses
provided in the periphery of a disc 15 mounted upon the cutter shaft to prevent
retrograde movements of the cutters after each intermittent movement. The disc 8
receives motion from the combing or card cylinder through the medium of toothed
gearing.
The hairs eliminated drop onto the delivering apron or table 3 which may be made
of slats or laths. The knives 1 are cleaned by a rotating brush 6 operated from any
suitable part of the machine.
This arrangement attains a result which hitherto has been accomplished but very
imperfectly or not at all, viz. that of cleansing or freeing fine wool from coarse hard
hairs, and the like, the loss of good, useful fibre being at the same time reduced to a
minimum, and the fibres under treatment being neither unduly strained nor damaged;
so that textile materials intermingled with coarse and rough hairs may, by the aid of
this invention, be successfully dealt with.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
:-
1. In combination with carding engines and in proximity to the drum a knife
moved intermittently and interposed between the device which raises the fibre and
the doffer, substantially as and for the purpose described.
2. The arrangements or combinations of parts constituting the apparatus herein-
before described and shewn respectively in Figures 1 and 2 and Figures 3 and 4 of
the accompanying drawings.
