Improvements in or relating to the Weighting of the Counter-
faller of Self-acting Mules.
I, ALBERT WINTGENS Sen., Foreman of Dahlhausen-Wupper, Germany 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:-
Until now one used for stretching the yarn by means of the counter-fallers of
self-acting mules constant weights, which were acting on the counter-faller by
means of a chain or the like and were imparting to the spun threads a constant
tension during the back-motion of the carriage, that is during the process of
copping the threads. But now every one knows that the shorter becomes the
thread, the greater is the tension which it may support. Therefore, if the threads
shall be wound upon the bobbins with the same strength during the whole process
of copping, there must be imparted to them a tension increasing gradually with the
beginning of the back-motion of the carriage, or in a few words: the shorter
becomes the thread to be wound up, the greater must be the tension imparted to
the same.
This fact indeed has been recognised by the men skilled in this trade
and the same have tried already to attain this end in several different ways. Still,
all these trials are characterized by the use of springs, which, during the back-
motion of the carriage, shall transmit to the counter-faller the tension which has
been imparted to them during the driving out of the carriage.
The mechanism represented in the annexed drawing solves the problem in a form
as simple and as sure as possible. The same rests on the principle that one and the
same force imparts a tension which is the stronger the more grows the lever-arm on
which acts this force.
Fig. 1 of the annexed drawing shows a sectional view through the carriage, the
new mechanism for stretching the counter-faller being disposed below the same.
In this figure the contrivance for connecting the carriage with the wheels has been
omitted, for the sake of greater clearness.
Fig. 2 represents on a greater scale the view from above of the new stretching
mechanism.
Fig. 3 finally shows a section through the stretching mechanism.

The contrivance consists of two rods S, S, at the extremities of which angular

plate P is connected with the carriage by means of a hinge D. On the frontside
of the carriage the plate P', is connected with the chain K, the latter going over
the bow B of the counter-faller, said plate carrying the weights G which are held
is
together by means of a pin. The front-plate P, as well as the back-plate P₂
provided sideways with vertical downward directed loops L, L, which serve as
bearings to the axles A, A,. On the axle A, which is situated on the backside of
the carriage, is fitted a pulley R (Fig. 1) to which the extremities of two ropes are
fastened in such a manner, that the pulley, through winding up one of these ropes
aud through winding off the other of the same, turus, during the back-motion of the
carriage, from the right to the left and during the driving out of the carriage, from
the left to the right. On the same axle A, a little chaiu-wheel C, is mounted in
the middle between the two rods S₁ S,; a similar chain-wheel is mounted at the
other extremity of the two rods on the axle A, that rests on the loops L. Over
the two wheels goes an endless chain E. On the two rods the weight H, the form
of which can easily be discerned in Fig. 3, is made to slide, this weight H being

page_text: fastly connected with one link of the chain so that the same, if the wheels C₁ C₂
turn from the right to the left and the chain in accordance therewith goes from the
right to the left, which action takes place during the back-motion of the carriage,
moves gradually as far as the other extremity of the two rods, whereby the tension
of the counter-faller, during the back-motion of the carriage, is gradually increased.
During the driving out of the carriage the weight H is to be brought back by
means of the described contrivance.
Of course the weight H as well as the weight G may be regulated by adding
some metal plates.
The action of the mechanism is immediately to be understood, if it be stated that
the axis of the hinge D of the back-plate P. coincides with the fulcrum.
As long as the weight H is still situated in its extreme position on the right, near
the plate P, the same presses the mechanism round about its fulcrum D froin the
right to the left; consequently, the tension imparted to the counter-faller owing to
the constant weight G is even partly annuled. As soon however, as the movable
weight, during the back-motion of the carriage, has been moved towards the left
beyond the fulcrum D, the same acts in the opposite way from the left to the right
and indeed with the more tension, the further the same is distant from the
fulcrum D, that is the greater is the lever-arm of the moment of rotation that is
acting round about D from the left to the right. Therefore the chain K too is
drawn with a gradually increasing tension, the more the weight H approaches of
its extreme position on the left.
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 I
claim is
In self-acting mules, in order to gradually increase the tension imparted to the
yarn by the counter-faller, during the back-motion of the carriage, the disposition
of a movable weight sliding over two rods fulcrumed on the back-side of the
carriage, said movable weight, as the counter-faller is disengaged and the carriage
returns back, sliding gradually from the back-side of the carriage to the other side
of the same, all substantially as described and for the purpose specified.
Dated this 6th of September 1895.
