IMPROVEMENTS IN FLYERS USED IN SPINNING AND DOUBLING PROVISIONAL SPECIFICATION
Year: 1881

page_text: LETTERS PATENT to Thomas Arthur Duncan, of Otley, in the County of
York, of the Firm of William Ackroyd and Co., Worsted Spinners, for an
Invention of "IMPROVEMENTS IN FLYERS USED IN SPINNING AND DOUBLING
PROVISIONAL SPECIFICATION left by the said Thomas Arthur Duncan at
the Office of the Commissioners of Patents on the 25th August 1881.
THOMAS ARTHUR DUNCAN, of Otley, in the County of York, of the Firm of
William Ackroyd and Co., Worsted Spinners. "IMPROVEMENTS IN FLYERS USED
IN SPINNING AND DOUBLING FIBRES."
My Invention has for its object improvements in flyers used in spinning and
doubling fibres, by which I am enabled to wind firmly on to the bobbins or spools
tender or soft twisted worsted or other fibres, and by confining the drag to a short
portion of the fibre under operation, I am enabled to spin sounder and better yarn
with less waste than heretofore.
Flyers are usually constructed with a curl or eye at the bottom end, and
some times with a curl upon the shoulder also, but according to my Invention I
construct the flyers with the curl at the bottom or extremities of the legs as usual,
but also with an extra curl or eye about midway or at other convenient position,
but under the turn of the shoulder, i. e., between the shoulder and the ends on the
straight part of the leg or legs, so that the fibre or end passing direct from the
roller or the eye of the top board of the spinning frame to the said eye or curl on
the straight part of the leg or legs, shall then be wrapped round the said leg or legs
of the flyer between the said eye or curl and the extremity of the leg or legs, and
then through the usual bottom eye or curl at the extremity. It will thus be wound
smoothly and firmly on to the bobbin. Of course the fibre may be passed straight
from the eye or curl upon the straight part of the leg through the bottom eye
without being twisted around the leg or legs of the flyer.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Arthur Duncan in the Great Seal Patent Office on the
22nd February 1882.
THOMAS ARTHUR DUNCAN, of Otley, in the County of York, of the Firm of
"IMPROVEMENTS IN FLYERS USED
William Ackroyd and Co., Worsted Spinners.
IN SPINNING AND DOUBLING FIBRES."
My Invention has for its object improvements in flyers used in spinning and
doubling fibres by which I am enabled to wind firmly on to the bobbins or spools

page_text: tender or soft twisted worsted or other fibres, and by confining the drag to a short
portion of the fibre under operation I am enabled to spin sounder and better yarn
with less waste than heretofore.
Flyers are usually constructed with a curl or eye at the bottom end, and
sometimes with a curl upon the shoulder also, but according to my Invention I
construct the flyer with the curl at the bottom or extremities of the legs as usual,
but also with an extra curl or eye about midway or at other convenient position
but under the turn of the shoulder, i. e., between the shoulder and the straight
part of the leg or legs, so that the fibre or end passing direct from the roller or the
eye of the top board of the spinning frame to the said eye or curl on the straight
part of the leg or legs shall then be wrapped around the said leg of the flyers
between the said eye or curl and the extremity of the leg or legs, and then through
the usual bottom eye or curl at the extremity. It will thus be wound smoothly
and firmly on to the bobbin. Of course the fibre may be passed straight from the
eye or curl upon the straight part of the leg through the bottom eye without being
twisted around the leg of the flyer..
In order that my Invention may be more clearly understood, I have appended a
Sheet of Drawings, showing a side elevation and plan of my new flyers which are
very similar when merely observed in a general way.
Figure 1 is a side elevation, and Figure 2 is a plan of my flyer; F, F, F, F,
represent the flyer; B, B, is the bobbin on which the yarn thread or other
fibre a, a, a, a, is being wound. Now the curl c, c, at the bottom end of each leg
is the usual carl given to flyers, and flyers have been made with a second curl on
the top of the shoulder d, d, but according to my Invention I place a curl e, e, on
each leg of the flyer at about the middle of its length, but the curl may be nearer
the top or bottom, but in all cases under the bend of the shoulder or on the straight
part of the leg, so as to confine the drag to as short a portion as possible of the
fibre under operation, which enables me to spin better and sounder yarn with less
waste.
Having now described my said Invention, I would have it understood that my
Invention is applicable to all spindles, whether for gill boxes, intermediate or
roving, or spinning frames, and what I claim as my. Invention and wish to
secure is:
Constructing flyers with an extra eye or curl in the leg or legs midway or at
other desired position underneath the shoulder and between it and the bottom curl,
and for the purposes described.
In witness whereof, I, the said Thomas Arthur Duncan, have hereunto set
my hand and seal, this 20th day of December, in the year of our Lord
One thousand eight hundred and eighty one.
