page_text: I, PIERRE BASTIN, of Roubaix, France, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
The subject of the present application is a system of superposed carders, the
multiple drum barrels of which form a covering or winding of several layers upon
a common comber.
Two drum barrels are arranged the one above the other the combing cylinder
doffing these two drum barrels being located behind the said drum barrels and
being in contact with both of them. The lower drum barrel is fed with material
by means of two little cylinders for opening which take it from a feeding apron,
the material is worked as in all carders, and then forms a layers upon the doffing
cylinder at the point of contact of this latter with the hereinbefore mentioned
drum barrel.
The material is supplied to the upper drum barrel by feed cylinders which take
it from a movable apron upon which the material is placed; the said upper drum
barrel being also capable of being fed by the large working cylinder of the carder
which has been previously mentioned, when this cylinder is approached near
enough to this carder for it to take the material, with the object which will be
specified in the course of the present description. In all cases and whatever
may be the source from which the second carding cylinder may derive its feed
the material which has been worked upon it is subsequently formed into a layer
upon the common doffing cylinder which has been hereinabove mentioned, but
at a point situated above the point of contact of that cylinder with the first carding
cylinder. The result of this is that whilst the fleece coming from this latter
cylinder is taken by the doffing cylinder, this latter possesses already a fleece from
the second carding cylinder: the two layers thus superposed upon the doffer
constitute a single fleece which will be taken off the doffer by the comb placed
behind this latter.
Supposing that blue fibres are being worked upon the first carding drum barrel,
and red ones upon the second, at the point of contact of this first drum barrel
with the doffer will be formed a blue layer which will be placed upon a red layer
previously furnished at the contact of the second carding drum barrel
with the same doffer; thus the fleece which will be taken off the
doffer by the action of the before mentioned comb will be partly red and partly
blue, so that by cutting up this fleece in a divider of any description, strands will
be formed which after drawing out and twisting will produce a thread equally
spun red and blue.
In many cases the feeding of the second carding drum barrel by means of a feed
apron can be dispensed with, this carding drum barrel being capable of being
fed by means of the large working cylinder of the first carding drum barrel
which supplies to this latter the material necessary to form the layer which being
worked upon the second carding drum barrel is passed to and drawn out on the
doffer cylinder; the fleece remaining upon the first carding drum barrel will

page_text: suffice to form the second layer at the point of contact of the first carding drụm
barrel with the doffer cylinder.

Improvements in Carding Engines,
I, PIERRE BASTIN, of Roubaix, in the Republic of France, Manufacturer, 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 present invention relates to a system of superposed cards the multiple drums
of which form a fleece of thicknesses or layers upon a common doffing cylinder.
The drawing hereto annexed shows a section of two superposed cards the drums
of which are arranged to discharge themselves upon a common doffing cylinder.
The cylinders A and B represent the drums, which have as a common doffer
the cylinder C. The material is supplied from the apron, K L, to the drum A,
by the feed cylinders or rollers H I. This material is worked in a similar manner
to that usual in all cards and forms a fleece or layer upon the doffer C at the point
of contact of this latter with the drum A.
The material is supplied to the drum B by the supply cylinder E which takes
or receives it from the feed cylinders or rollers O, P, which receive it from a cloth
or apron M. N, or else from the large operating drum D of the card A, if it be
approached sufficiently near to this cylinder or roller to take the material there-
from. The fibres or filaments after having passed through the different parts,
finally form a fleece or layer upon the doffer C at the point of contact V with the
drum B.
The two fleeces or layers thus superposed form a fleece of a special description
which will be detached from the doffer by means of the comb X.
Let us now suppose that fibres or filaments of a blue colour are being worked
upon the drum A, and fibres or filaments of a red colour upon the drum B, at the
point T will be formed a blue layer which will be placed upon a red layer which
has been previously formed at the point V. The fleece which will be detached from
the doffer under the action of the comb X will be partly red and partly blue so
that when it is cut up by any suitable dividing apparatus it will form strands
which after being drawn out and twisted will form an equally twisted red and
blue thread.
This however is not the principal advantage of the invention. The most marked
improvement consists in the fact that the fleece is formed by layers instead of being
made in a single throw or operation, this piece of double fleece necessarily giving
a greater regularity in the thickness of the fleece and preventing the empty
spaces which would be caused by cuts in the prepared strands. A more perfect
carding can likewise be obtained than is possible with the existing systems.
As has been herein before stated, it is possible in many cases to do away with
the feeding of the card B by the feeding device O, P, in as much as that carder
may be fed as well by taking the supply of material from the large operating drum
or cylinder D of the carder A, which is necessary to form the layer at the point V,
the additional or extra material which will remain upon the drum A being
raised by the flier F and sufficing for the formation of the second layer at the

page_text: point T. This division of the material between the two cards constitutes a
further improvement comprised in the invention.
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:
-
The system of superposed cards to cards with multiple drums supplying the
carded fibres or filaments to a common doffer, where the fleece is formed in
successive layers instead of being completed at a single throw or operation,
substantially as hereinbefore described and illustrated in the annexed drawing.
