Improvements in or relating to Carding-engines.
I, CARL SCHMIDT, of No. 31 Bismarkstrasse, Forst i/Lausitz, in the Kingdom
of Prussia, German Empire, Spinning Manager, do hereby declare the nature of
this invention to be as follows :-
The objects that it is desired to attain by carding; namely, the production
of extreme uniformity in the slivers; the intimate intermixture and perfect
disentanglement of the wool or cotton treated, the uniform distribution of the
wool or cotton throughout the fleece, and the separation of such impurities as
may still be present, have not, until recently been attainable, without employing
a set of generally three, and sometimes even four, carding-engines. There have,
indeed, been endeavours to attain these objects with a set of two machines by
providing each of them with a breast-cylinder with two or three workers; but
even under these conditions two machines could not be made to satisfactorily
work up either wool or cotton or a mixture of these, that is knotty and difficult to
disentangle.
Now according to one part of my invention I attain these objects with two
carding-engines without breast-cylinders, by means of apparatus adapted to take
the material that is not yet sufficiently worked off one of the last workers and
automatically carry it back over one or more workers and then again introduce into
the machine thus causing it to be subjected to the mutual action of the cylinder,
workers, and clearers, as often as may be required.
In the accompanying illustrative drawings,
It

engine provided with apparatus according to this part of my invention.
comprises an endless apron arranged in connection with, for example, the last
worker a' of the carding-engine. The material not yet sufficiently disentangled is
combed off the work a by a comb b and allowed to drop on the apron c¹ from
which it is taken by a roller d' and transferred to a long endless apron e by means
of which it is taken back over one or more, or if required the whole, of the workers
and clearers. By means of a roller d', the fleece or web of material is transferred
from the aprone to a smaller apron from which it is carried by another roller d³
to the clearer f which transfers it to the cylinder T.
It will thus be seen that the material that is not yet sufficiently disentangled,
that is to say, has not the required degree of uniformity after having passed once
through the engine, is returned to the engine either between two workers or at the
place at which it originally entered the engine, and only leaves the engine after
the objects above enumerated have been attained.
Apparatus such as described may be applied to both of the carding-engines
employed. If the material under operation is easy to disentangle the apparatus is
thrown out of action by simply raising the comb 6; the material then pursues the
ordinary course. Two advantages are hereby obtained: material easy to dis-
entangle is not unnecessarily shortened by being kept too long under treatment ;
and, when necessary, knotty material can be easily disentangled.
This invention not only secures the advantage of a smaller outlay for plant by
enabling two simple carding-engines to be employed where, hitherto, two, and as a
rule three, carding-engines with breast-cylinders have been considered necessary,
and effecting an economy of space and motive power, but also enables an increase
in output to be obtained through the considerably less time taken up by stripping

page_text: as only two machines require to be stripped in each set; moreover, on account of
this fact the waste of material is considerably reduced.
The arrangement described above has also the effect of producing a more uniform
result, since the material taken off the worker is made to unite with material that
has entered the engine at a later stage. Thus, if in consequence of inattention or
otherwise, the engine is somewhat irregularly fed, the larger and smaller feeds will
unite and an equalization will be thus brought about.
The second part of my invention has for object to considerably increase possibly
two-fold the output of material without in any way interfering with its quality, for
which purpose, a fleece or web is taken off the last worker.
In the accompanying drawings,
Fig. 2 represents diagrammatically and by way of example only two methods of
carrying out this part of my invention.
According to one method, an additional apron shown in dotted lines, is
arranged in connection with the last worker a', so as to transfer a fleece or web
therefrom to the fleece-roller P, as in the case of the doffer. Thus as the material
is taken off the cylinder at two different places, the engine is cleared much more
rapidly, and a correspondingly greater quantity of raw material can be fed thereto.
Instead of transferring the fleece or web from the worker to the fleece-roller P, it
may be transferred by means of an apron arranged as shown in dotted lines at cor
in any other suitable position, to a combined carding-engine and slubbing-machine
or to a condensing or other desired machine or be merely delivered as a
continuous fleece or web to be subsequently dealt with in any desired way.

Improvements in or relating to Carding-engines.
I, CARL SCHMIDT, of No. 31 Bismarkstrasse, Forst i/Lausitz, in the Kingdom
of Prussia, German Empire, Spinning 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 :-
The objects that it is desired to attain by carding; namely, the production of
extreme uniformity in the slivers; the intimate intermixture and perfect dis-
entanglement of the wool or cotton treated, the uniform distribution of the wool or
cotton throughout the fleece, and the separation of such impurities as may still be

into the machine thus causing it to be subjected to the mutual action of the
cylinder, workers, and clearers, as often as may be required.
In the drawings filed with my Provisional Specification,
Fig. 1 shows by way of example only, a diagrammatic elevation of a carding-
engine provided with apparatus according to this part of my invention.

in connection with the last worker a¹, so as to transfer a fleece or web therefrom
to the fleece-roller P, as in the case of the doffer. Thus as the material is taken

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. A carding-engine provided with means whereby cotton, wool, or the like that
has not been sufficiently worked by one passage through the engine can be
conveyed back from one of the last workers and reintroduced into the said carding
engine behind one of the preceding workers, or at the entrance end of the engine as
set forth.
2. In a carding-engine transferring or conveying apparatus constructed arranged

page_text: and operating substantially as hereinbefore described with reference to Fig. 1 of
the drawings for the purpose specified.
3. A carding-engine provided with means such as an endless apron c or c³
adapted to take a portion of the wool cotton or the like passing through the engine
from one of the workers and deliver it, independently of that taken off by the
doffer, to a combined carding-engine and slubbing-machine or to any other desired
machine or device, or to simply deliver it as a continuous fleece, substantially as
hereinbefore described.
