page_text: LETTERS PATENT to John Clough, of Haincliffe, in the Parish of Bingley, in
the West Riding of the County of York, Worsted Spinner and Manufacturer
for an Invention of "IMPROVEMENTS IN APPARATUS FOR PREVENTING WASTE
IN THE OPERATIONS OF TWISTING AND DOUBLING YARNS AND THREADS."
PROVISIONAL SPECIFICATION left by the said John Clough at the Office of
the Commissioners of Patents on the 11th May 1880.
JOHN CLOUGH, of Haincliffe, in the Parish of Bingley, in the West Riding of
the County of York, Worsted Spinner and Manufacturer. "IMPROVEMENTS IN
APPARATUS FOR PREVENTING WASTE IN THE OPERATIONS OF TWISTING AND
DOUBLING YARNS AND THREADS."
This Invention relates to improved apparatus for preventing waste in the
operations of twisting or doubling yarns and threads.
The bobbins containing the yarns or threads to be twisted or doubled are placed
on tubes running freely upon pegs carried by a cross-rail, and the bobbins and
tubes are caused to rotate together by means of pins projecting from wings, plates,
or extensions of the latter, and engaging with recesses or holes in the former. The
tubes are provided with other 'extensions or stopping-plates, which are situated
nearer the bottom end thereof, and are acted upon by the means and with the
result hereinafter described.
In connection with this arrangement I use a balanced or centrally mounted lever,
a forward arm of which extends to over the centre of the spindle carrying the
bobbin on which the twisted or doubled threads are to be wound, and is thero
provided with an eyelet or pot-guide, through which the twisted or doubled threads
pass on their way from the ordinary horizontal drawing rollers of the spinning or
doubling frame (and by which they are drawn from the first mentioned bobbins) to
the bobbin on which they are to be wound in the ordinary way; and rearward
arms of which extend sufficiently far to engage with the said stopping-plates of the
first mentioned bobbins, when a breaking of either of the threads takes place, upon
n

page_text: which the drag of the bobbin on which the twisted or doubled threads are wound
breaks the other thread, whereupon the lever is no longer balanced at its forward
end, and so allows of its rearward arms falling and engaging with the stopping-
plates of the first mentioned bobbins, thus preventing then revolving or delivering
any more thread to the drawing rollers, and thus accomplish the object of the
Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Clough in the Great Seal Patent Office on the 11th November
1880.
JOHN CLOUGH, of Haincliffe, in the Parish of Bingley, in the West, Riding of
"IMPROVEMENTS IN
the County of York, Worsted Spinner and Manufacturer.
APPARATUS FOR PREVENTING WASTE IN THE OPERATIONS OF TWISTING AND
DOUBLING YARNS AND THREADS."
This Invention, which relates to improved apparatus for preventing waste in the
operations of twisting or doubling yarns and threads, is illustrated on the
accompanying Sheet of explanatory Drawings in sectional elevation in Fig. 1, and
in plan view in Fig. 2.
The bobbins 1 containing the yarns or threads 2 to be twisted or doubled are
placed on tubes 3 running freely upon pegs 4 carried by a cross-rail 5, and the
bobbins and tubes are caused to rotate together by means of pins 6 projecting from
wings, plates, or extensions 7 of the latter, and engaging with recesses or holes in
the former: The-tubes 3 are provided with extensions or stopping plates 8, which
are situated nearer the bottom end thereof, and are acted upon by the means "and
with the result hereinafter described.
In connection with this arrangement I use a balanced or centrally mounted
lever 9, a forward arm 10 of which extends to over the centre of the spindle 11
carrying the bobbin 12 on which the twisted or doubled threads are wound, and is
there provided with an eyelet or pot-guide 13, through which the twisted or
doubled threads pass on their way from the ordinary horizontal drawing rollers 14
of the spinning or doubling frame (and by which they are drawn from the
bobbins 1) to the bobbin 12 on which they are to be wound in the ordinary way;
and rearward arms 15 of which extend sufficiently far to engage with the stopping
plates 8 of the bobbins 1, when a breaking of either of the threads 2 takes place,
upon which the drag of the bobbin 12 breaks the other thread, whereupon the
lever 9 is no longer balanced at its forward end 10, and so allows of its rearward
arms 15 falling and engaging with the stopping plates 8 of the bobbins 1, thus
preventing them revolving or delivering any more thread to the drawing rollers 14,
thus accomplishing the object of the Invention.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that what I claim as the Invention secured to
me by the hereinbefore in part recited Letters Patent is,-
The new and peculiar application to spinning or doubling. frames of a series of

page_text: balanced levers, the position of which is controlled by the twisted or doubled
threads passing from the ordinary horizontal drawing rollers to the bobbins on
which they are to be wound, and which levers upon any breakage of the threads
are released so as to engage with stopping plates or extensions on the tubes, or
other means by which the bobbins containing the yarns or threads to be twisted or
doubled are carried and revolved, so as to prevent the latter revolving or delivering
any more of the yarn or thread to the drawing rollers until the severed threads are
again united, for the purpose of preventing waste in the above referred to
operations, the whole being substantially as and for the purposes hereinbefore
described.
In witness whereof, I the said John Clough, have hereunto set my hand and
seal, this Sixth day of November, in the year of our Lord One thousand
eight hundred and eighty.
Signed, scaled, and delivered, by
the above-named John Clough,
