"IM-
PROVEMENTS IN SELF-ACTING SORTING AND DRAWING APPARATUS APPLIED TO
CARDING ENGINES USED FOR CARDING WOOL OR OTHER FIBROUS SUBSTANCES.'
[A communication from abroad by Louis Philippe Messelier, of Tourcoing, in the
Republic of France.]
This Invention consists of a new arrangement of self-acting sorting apparatus
applied to carding engines, and has for its object the separation of the long fibres
and the formation of a band or sliver of combed wool or other fibrous substance,
uniform in its character and having its fibres sorted to lengths about equal.
By this Invention a quantity of long fibre is removed dependant upon the nature
of the material which is being treated and the extent of regularity which it is
desired to obtain; and it may vary from one to fifteen per cent. or more. The
ribbon or sliver thus obtained being freed from such fibres which do not amount in
most cases to more than from three to five per cent. becomes reduced to ninety-five
to ninety-seven per cent. of the total quantity treated, and is of a uniform fineness,
and composed of even and regular fibres, a result of great value on account
of the advantages which accrue in the processes of spinning and manufacture.
The fibres removed amounting to from three to five per cent. from another and
commoner sliver.
The improved apparatus may be applied to carding engines of different systems
of construction.
The accompanying Drawing is in illustration of the Invention; a is part of the
drum or cylinder of a carding engine; b represents the drawing apparatus ordinarily
used, in which the fibres are drawn first through a funnel-shaped space, and afterwards
through compressing apparatus; c, c, are drawing and sorting cylinders, the position
of which is capable of being adjusted nearer to or further from the cylinder a,
according to the nature of the material to be treated and the per-centage of fibres to

shewn, and serving to straighten the fibres and deliver them in a horizontal position.
It is held by moveable supports which allow its position to be varied; f is a
stretching roller round which passes the endless leather band g, the surface of which
is suitably grooved or fluted; h is a guide of polished metal placed obliquely, its
lowest part being arranged near the roller c and serving to support the separated
fibres which are rolled upon the leather.
The action of the apparatus is as follows:-The cylinders c, c, being adjusted at
a distance from the large cylinder a, proportioned to the character of the separation
and sorting which are to be effected, take up the long fibres which are to be
extracted; these are then brought to the proper position by the guide d, and by
means of the fluting upon the leather become rolled together round it and form a
flat ribbon or sliver, which is broken off as desired. These flat ribbons or slivers
are afterwards amalgamated and united by passing them through the apparatus
well known as a "gill box," which converts them into a regular and even ribbon
or sliver.
