COMPLETE SPECIFICATION.
An Improved Machine for Winding Yarn or Thread.
I, CHARLES SIMON, of No. 13, Albananlage, Bâle, in the Republic of
Switzerland, Engineer, 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 the construction of an improved spooling machine.
It is well known to spinuers and weavers that the machines called weft winding
machines for the most part are not capable of winding on thin spindles as they
cause the cops to be wound of irregular size and firmness and possess other defects
with the result that they cause bad weaving as the crossing of the ascending and
descending layers is always very defective with these machines. These incon-
veniences and defects arise owing to the threads drawn by the spindles not
having a regular tension this depending upon the condition of each bobbin
feeding the spindles which varies with the diameter, the length remaining on
the spindles, the inequalities of the surfaces &c. whether these bobbins become
unwound by winding off or from the points. This tension is still more variable
when hanks or skeins are being wound on bobbins or spools.
For these reasons such machines are but little employed for spinning which, by
reason of the exigencies of the weaver, is confined to bobbins of regular and perfect
shape hitherto obtained only on "self acting "mules. Their employment is
confined to weavers who would derive great advantage in making perfect hobbins
for themselves seeing that they insist upon having them perfect when buying
them.
On the other hand as the produce of ring throstle frames is from two to four
times as great as that of "self-acting" machines according to the material, attempts
have been made to make the untwisted weft into cops directly on these throstle
frames. These attempts have always failed when it has been required to wind
delicate or fine spun thread on spindles the diameters of which are as small as
those of the self-acting machines. Each thread has its proper tension given by
the ring traveller and the cops in this case also become irregular and not sufficiently
firm.
In view of the large production which can be obtained with throstle frames
spinning onto large tubes there is an advantage in so spinning the weft and placing
it in cops on a special machine having the properties of the "self-acting" machine
from the point of view of the formation of the cops, and further a much larger
production which compensates for the hand work of this special machine.
To this end I have devised a machine which will be hereinafter described for
winding the thread into cylindro-conical cops with a regular feed by cylinders and
winding on the spindles by means of driving gear which imparts to the latter a
movement of rotation regulated by a compensated faller giving at the same time
a uniform tension to the threads during the whole operation of forming the
cops which in this manner are wound as regularly as by the "self-acting
mules.
"
In order to enable my invention to be fully understood I will describe the
same by reference to the accompanying drawing, in which
Figure 1 is an elevation of my improved bobbin-winder the upper part of the
front frame being removed.
Figure 2 is a plan of a part of the apparatus.
A and A are two cylinders surmounted by a pressure cylinder B; these
exlinders turn with a constant speed and furnish to the spindles the thread which

page_text: passes over the faller wire c supported by end arms F and intermediate sickle-
shaped supports E connected to the shaft C of the faller which shaft gives under
the action of an adjustable counterweighted lever D, the desired tension to all the
threads g, of the apparatus which can be single or double. The counter-
weighted lever D is connected by a rod V and a metal riband X to an arm
carrying a segment Z the said arm being fixed to the shaft C of the faller.
In order that this faller c may be capable of adapting itself to the slightest
movement of the threads and be free from the inconveniences possessed by the
fallers and counter-fallers of the self-acting mules I have nullified the effect of
the drag of the thread of the faller on the two end arms F and consequently
on the shaft C by another wire c' stretched between continuations of the two end
arms F.
In this manner the shaft C of the faller rests in a perfectly straight line and
requires but few supports along its length which increases the sensitiveness of this
faller which I term compensated faller. The pull of the faller c on the shaft C
being nullified by the wire c' the shaft C remains as above described in a perfectly
straight line without any tendency to sag thereby allowing of it resting on rollers
instead of fixed supports.
A further function of this compensated faller is to regulate the speed of winding
of the spindles to its proper rate and such as it should be at each downward and
upward movement of the carriage G by the intermediation of the brake N H H
and of the friction clutch I, O. The initial speed of the drum J which drives the
spindles is given in order that the first layer of thread may be rolled on the tube,
the brake being completely loosened.
C
In proportion as the layers of the base or first layers are formed and increase in
diameter the faller e acts under the greater tension of the threads g and descends a
little towards the spindles while the roller K fixed on one of the end arms F, F, of
the faller moves in an upward direction the length of the curved part of the bent
lever L jointed to the end frame of the machine and causes this lever to oscillate
on its pivot and by means of the rod M and the brake lever N causes the
brake strap or chain to gradually tighten on the brake pulley H keyed on
the shaft of the drum J which drives the spindles and is driven by the friction
clutch I, O.
This gradual tightening of the brake reduces the speed of movement of the shaft
of the drum J the friction plate I keyed on the shaft slides on the pulley-plate
loose on the said shaft and driven by a band from a pulley Of fixed on the
prolonged shaft of one of the cylinders A or A'. It is obvious that movement can
be equally well communicated by gearing. The friction plate I is pressed against
the plate by a helical spring P which surrounds the shaft of the drum J; the
tension of the spring is regulated by means of nuts.
The whole being in position the faller is slowly lowered with the carriage G
which guides the thread over crossing diameters and is raised with the said carriage
when the inverse movement is produced.
The power of the brake and of its parts is combined in order that for all the
threads of the machine a very slight effort is necessary to apply the brake. The
operation is so sensitive and so perfect that a few cops only can be made on a
machine which the movement of the fallers and of the other parts does not allow
with self-acting machines. For fine numbers the necessary tension of the threads
for tightening the brake can be compensated by a regulator composed of a lever
arm Q fixed to a friction plate U on a shaft m which produces the to and fro
vertical movement of the carriage G and provided with a finger T fixed thereto, so
that the said arm is operated by the shaft m through a friction arrangement and
has consequently an alternate or oscillating movement around the axis of the
shaft m.
Upon the upward movement of the carriage G at the moment when
the faller c rises the arm Q is moved down through friction by the shaft m and the
finger T fixed to the arm Q, moving with the latter, presses upon the spring R of
the lever D so that this lever becomes loaded, in addition to the weight adapted

page_text: thereto, with a supplementary pressure exerted thereon by the spring R. This
supplementary pressure causes the descent of the lever D thus effecting the
loosening of the strap-brake and, consequently, simultaneously increasing the speed
of the winding spindles. During the upward movement of the carriage G the
downward movement of the levers D and Q continues until the lever Q comes.
against the screw S. At this moment, the lever Q being prevented from moving
further downward by the said screw S, the friction plate U ceases to be carried
round by friction by the shaft m during the very small remainder of time.
occupied in the ascending movement of the carriage G. By turning the screw S
in one direction or the other the supplementary pressure exerted by the finger T
on the spring R and consequently on the lever D can be caused to cease sooner
or later, that is to say, by this screw the duration can be regulated of the
part of the ascending movement of the carriage G during which the lever Q
exerts a supplementary pressure on the lever D causing the loosening of the
brake.
The set screw S adapted to the frame of the machine limits the action of the
lever arm Q.
Such are the means by which I attain the object desired of winding large bobbins
with warp threads from hanks, or weft threads on throstle frames but I reserve
to myself the right of applying these means to any other machines to which they
are applicable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what [
claim is :-
C
(1). A machine for winding threads into cylindro-conical cops in which the
threads delivered or fed regularly by cylinders A. A' B. receive a uniform tension
by a faller c acted on by a counterweighted lever D connected to an arm Z of the
shaft C of the faller, while this faller further regulates the speed of rotation of the
spindles by a roller K fixed to one of the arms F of the shaft of the faller and
acting on the curved arm of a bent lever L actuating the lever N of a band or
chain brake the pulley H' of which is fixed on the shaft of the drum J which
transmits the movement of rotation to the spindles and is driven from one of the
feed cylinders A A' B by a friction clutch I. O. the whole forming a differential
movement of great simplicity.
(2). The combination of the end arms F. F. supporting the faller c and connecting
it to the shaft C and having prolonged parts joined by a second wire c' stretched
between them nullifying the pull or drag of the faller c on the two arms F. F. and
consequently on the shaft C so that this shaft rests in a perfectly straight line
which diminishes the number of supports required by this shaft and gives a certain
quickness of action to the faller termed "compensated faller."
(3). The combination of the arrangement claimed in Claim 1 with a regulating
apparatus consisting of a lever arm Q actuated by the driving shaft of the
carriage G and provided with a finger T fixed thereto and combined with a set
screw S and which on the upward travel of the carriage and the faller presses on a
spring R adapted to the counterweighted lever D for the purpose of rendering the
tension of the thread uniform and of forming the cops with firm and compact points,.
that is to say with the thread tightly wound.
