Improvements relating to Carding Engines.
I, WILHELM GEILE, Spinnery Technologist, of Speyer a/Rh., in the Kingdom of
Bavaria, 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:-
The subject of my invention is an arrangement for complete removal of dust
and waste in the carderies of cotton-mills. Formerly there was produced much
dust and waste with the cleaning of cotton by the usual carding-engines in the
respective rooms, whereby the air in the workroom became infected and very
unwholesome. Therefore improvements have been already tried to meet the case by
bringing to or sucking off the air by ventilation-systems; but these arrangements
did not succeed, because a renovation of the air is of no use against the continually
whirling up of the dust. What caused the most complaints in this regard is the
cleaning of the revolving covercards by the cleaning brushes, wherefore many
cotton mills have taken up again the former method of cleaning by hand, although
this manipulation does not afford a relief to the workers employed.
The chain of revolving cards is another place for accumulating dust. This
also becanes disadvantageous, not only in hygeian relation, but also respecting
the management and the mechanical effect of the card itself. From the dust
accumulating there result lumps which are pressed together by the driving wheels
of the flats, whereby the flats moving round these wheels are pressed against the
stripping-brush of the flats so that it stops and their garnitures are damaged.
Otherwise, small lumps are cramped between the flats on the large inner side
whereby the position of the covers to the cylinder is altered, and lastly the links
of the chain are always covered with dirt which never can be removed by cleaning
wheels etc.
The subject of my invention which easily may be applied to present engines
consists in an arrangement that removes the dust and waste arising from these
engines in its origin and therefore prevents it from entering into the workrooms
as well as from soiling the cotton being in preparation.
The invention consists on the one hand in the arrangement of a case fixed above
the stripping brush for cylinder and doffer, the case bears an interior channel
and an outward socket-piece for the leading away of the dust and waste
accumulated there. This piece can be applied on either side, according to the
side on which brushes are to be driven. The case encloses the stripping brush
set on the cylinder, lying on the cylinder.
Otherwise the invention consists in that the air trunk of the chain of flats is
ntroduced between the flats and consists of a tube having a slit to the back of
he flats this tube is closed on one side and brought in connexion on the other
side with a suction-channel, whereby the dust which has penetrated through
he flats is sucked off, and the air in the work-room renewed. A strip of
eather (G2) applied on the side of the tube towards the comb hinders the sucking
f the waste on the flat through the flat-chain.

Fig. 1 a disposition representing the arrangements of my invention,
Fig. 2 a longitudinal view of the case of the stripping-brushes,
Fig. a cross-section to A B of the Figure 2 and the
Fig. 4 a side-view of it,
Fig. 5 & 6 a longitudinal section, respectively a cross-section through the
arrangement for the sucking of the waste on the flat.
Fig. 7 & 8 a form executed (for instance) for the junction of the vertical pipe F
with the main air trunk F1 of an entire row of engines.
For this purpose the two stripping brushes (A) & (B) Fig. 1 on the cylinder
and doffer are enclosed by a case (D), made of tin-plate and of cast-iron plates and
inserted between the brush-bearings (C). The upper part of the case is formed
into a tube (D). which is open on one side and in which the dust and waste is
driven in consequence of the rotation of the brush-cylinder; from the tube the
dust and waste is conducted by a socket-piece with a hose (E) and by the channel
(F) which is supported vertically in the frame of the card and carries on the
bottom a tractive and regulating register (F2): from there the dust and waste
is led away into a suction-channel (F1) common to a row of engines. The remova!
of the coverdust and the waste of the revolving covercards (L L, Fig.1) is effected
by the hollow trunk (G), introduced between the endless chain of cards on the
whole width of the engine; this trunk is open on the under side (G1), from where
the dust accumulated on the flats is conducted to it by the sucking-effect of the
suction-conduit (FFI) for the purpose to lead the dust away-The trunk (G)
is closed on the one side (the driving side) respectively formed to a pivot ()
open on the other side going over into the vertical channel and supported ou
both sides by closed bearings. By means of the channel F the pipe (G) is
connected with the main channel (F1) which is common to a row of carding-
engines, in the manner shown in Fig. 7. Eventually the opening of the channel
can be closed by the cover-plate (H) Fig. 8.
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:
An inserted arrangement for the purpose of expelling the dust from the cylinder
and doffer as well as removal of the accumulation of dust upon the flats of the
carding engines of cotton-mills, so characterized that on the one hand betwee
the bearings of the stripping brushes of the cylinder and doffer, a case is applic
which bears in itself still a tubular room for accumulating dust, open on the on
side to the length of the drum and which is closed on the one end, but connecte
on the other end with the suction-conduit common to a number of engines i
one row also an arrangement in which a hollow trunk closed on the one side an
open in its whole length by a slit, is introduced between the revolving flats o
these cards; the open end of the trunk, which is led out being brought int
connexion with the suction-conduit.
