This Invention, which relates to improvements in winding and folding yarns or
threads, has for its object to ensure that that number of yarns or threads which it
is desired to fold together shall invariably be delivered to the winding bobbin,
and, further, to stop the rotation of the winding drum when any one of the yarns
or threads being folded together breaks or otherwise fails to be delivered to the
bobbin. For these purposes a pulley placed on the main shaft of the winding
frame, and another pulley on an intermediate shaft, the two pulleys being connected
by a belt or band. On the intermediate shaft a "paddle or apparatus consisting
of two discs connected together by bars or rods is situated loosely, and geared with
the shaft by means of a spring or retarder, which is connected to the paddle and to a
hoop fixed on the shaft. A second pulley is placed on the intermediate shaft, which
drives the winding drum by means of a belt passed round that pulley and round a
similar pulley on the spindle of the drum. The winding bobbin, which is situated
in proximity to the drum, is driven by frictional contact therewith. In a series of
sockets formed or fixed on a bar or plate situate above the paddle before referred
to guides are carried, the number of these corresponding to the number of threads
or yarns being folded and wound together. Through these guides, which consist of
metal rods with eyes at their upper ends, the yarns or threads are so passed that
when the machine is in operation the guides are suspended by the threads or yarns,
but when one thread or yarn breaks its guide falls, and the lower extremity
thereof striking against one of the cross bars or rods of the paddle stops the rotation
of the intermediate shaft and of the winding drum and bobbin until the broken

page_text: thread is pieced or tied up again, and the guide raised from contact with the paddle
by means of a spring lever provided for that purpose.
In stopping the winding and folding, as above set forth, the spring or retarder by
which the paddle is geared with its shaft so acts as to prevent the other threads
or yarns from being strained or broken by the sudden check or stoppage of the
apparatus.
A separate apparatus constructed as herein-before described is provided for each
winding drum of the frame.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John France in the Great Seal Patent Office on the 23rd April
1877.

"IMPROVEMENTS IN WINDING AND FOLDING YARNS, AND IN THE MACHINERY OR
APPARATUS EMPLOYED THEREFOR."
My said Invention, which relates to improvements in winding and folding yarns or
threads, has for its object to ensure that that number of yarns or threads which it is
desired to fold together shall invariably be delivered to the winding bobbin, and,
further, to stop the rotation of the winding drum when any one of the yarns or
threads being folded together breaks or otherwise fails to be delivered to the
bobbin.
.
And in order that my said Invention may be properly understood I now proceed
more particularly to set forth the system, mode, or manner in or under which the
same is or may be used or practically carried into effect, reference being had to the
annexed Sheet of Drawings and to the letters and figures marked thereon, that is to
say-
On the Sheet of Drawings hereunto appended Figure 1 is a transverse section;
and Figure 2 a front elevation of parts of a winding frame having the apparatus
constituting my said Invention shewn applied thereto."
As seen by these Figures a pulley a is placed on the main shaft b of the winding
frame, and another pulley c on an intermediate shaft d, the two pulleys being con-
nected by a belt or band e. On the intermediate shaft d a "paddle" or apparatus
consisting of two discs f, connected together by bars or rods g, is situated loosely
and geared with the shaft d by means of a spring or retarder which is connected to
the paddle and to a hoop or disc h fixed upon the shaft d.
Figure 3 of the Drawings is an enlarged detailed view of one of the end discs of
the "paddle," shewing one method under which the spring or retarder k may be con-
nected thereto, and to the hoop or disc, but instead of so connecting it the said
spring or retarder may be varied in form or construction, and connected in any
other suitable manner.
A second pulley is either placed firmly on the intermediate shaft d, or connected
to or formed on the hoop or disc (or it may be connected to one end of the
spring k, and in that case the hoop or disc is dispensed with). The said pulley
drives the winding drum m by means of a belt passed round that pulley, and round
a similar pulley n on the spindle of the drum. The winding bobbin o, which is
situated in proximity to the drum m, is driven by frictional contact therewith.

In a series of sockets s formed on or fixed to a bar or plate r, situate above the
' paddle" before referred to, guides p, which consist of metal rods with eyes at their
upper ends, are carried. Through these guides the yarns or threads to be folded
together on the bobbin o are so passed from the bobbins t on the pins of the peg
board u that when the machine is in operation the guides p are suspended by the
threads or yarns, but when one thread or yarn breaks its guide falls downwards in
its socket, as indicated at A, Figure 2, and the lower extremity of the guide striking
against one of the cross bars or rods g of the "paddle" stops the rotation of the

page_text: 66
intermediate shaft & of the winding drum m and of the bobbin o until the broken
thread is pieced or tied up again, and the guide raised from contact with the
paddle." This raising of the guide is effected by means of a spring lever w, with
which each guide is furnished, the spring being provided for the purpose of exerting
a slight tension on the thread or yarn, and of ensuring that the guide will sink
downwards into contact with the "paddle" immediately on a thread or yarn being
broken. The number of guides p provided in connection with the drum m determines
the maximum number of threads that may be wound or folded by the drum on to
the bobbin o at one time, but some of the guides may be when desired rendered
inoperative, or adjusted in order that any number of threads less than the maximum
may be so wound.
In stopping the winding and folding of the yarns, as herein-before set forth, the
spring or retarder k, by which the "paddle" is geared with its shaft so acts as to
prevent the threads or yarns from being strained or broken by a sudden check or
stoppage of the apparatus, the spring permitting the drum m and intermediate
shaft d to rotate after the "paddle" is stopped, and until the increasing retarding force
of the spring due to its compression by being wound up overcomes the friction of
the belt or band on the pulley c. When this is effected, which it is in a very short
time after the "paddle" stops, the drum m and bobbin o become stationary, the
belt or band e running round the pulley c without rotating the intermediate shaft d.
To prevent those yarns or threads being wound and folded together from becoming
twisted in the operation, and which might otherwise be the case if the bobbins are
not properly adjusted, and the threads or yarns from them allowed to overrun each
other, each yarn or thread passes through a compensator x between the guide p and
the bobbins t on the pegboard . This compensator consists of a bracket bolted,
screwed, or otherwise fixed to the under side of the pegboard u, and carrying a shaft
whereon are loosely situated a series of fingers or bars having loops or eyes at their
outer ends. The threads or yarns are passed through these eyes or loops, and any
slack being so taken up overrunning is prevented.
A separate apparatus, constructed substantially as herein-before described and
shewn on the Drawings, is provided for each winding drum of the frame, so that
when one drum is stopped the working of the other drums of the frame is not
interfered with.
Between the compensator and the guides the threads or yarns are preferably made
to pass over a glass rod y.
The apparatus may also be employed in winding or folding yarns on to spindles
as well as on to bobbins, and it may be further used in winding single yarns on to
bobbins and spindles when two or more yarns are not to be folded together.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the system, mode, or manner in or under which the same is or may be
used or practically carried into effect, I would observe in conclusion that what I
consider to be novel and original and therefore claim as the Invention secured to
ance by the hercin-before in part recited Letters Patent is, the apparatus consisting
of the "paddle", and meclianism connected therewith, whereby it is geared with
the main shaft of the winding frame and with the winding drum, and the employ-
ment of the said apparatus in winding and folding yarns and threads on to bobbins
and spindles, substantially as herein-before described with reference to the Sheet of
Drawings hereunto annexed.
In witness whereof, I, the said John France, have hereunto set my hand and
seal, this Twentieth day of April, One thousand eight hundred and seventy-
