IMPROVEMENTS IN TWISTING FRAMES
Year: 1868

page_text: LETTERS PATENT to John Pickles, Edward Ramsbottom, Samuel
Haggas, Samuel Foulds, Joseph Shackleton, all of Bingley, in the
County of York, and William Berry, of Bradford, also in the County
of York, for the Invention of "IMPROVEMENTS IN
TWISTING FRAMES."
Sealed the 4th June 1869, and dated the 11th December 1868.
PROVISIONAL SPECIFICATION left by the said John Pickles, Edward
Ramsbottom, Samuel Haggas, Samuel Foulds, Joseph Shackleton,"
and William Berry, at the Office of the Commissioners of Patents,
with their Petition, on the 11th December 1868.
We, JOHN PICKLES, EDWARD RAMSBOTTOM, SAMUEL HAGGAS,
SAMUEL FOULDS, JOSEPH SHACKLETON, all of Bingley, in the County of
York, and WILLIAM BERRY, of Bradford, also in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SPINNING AND TWISTING FRAMES," to be as follows:-
Our Invention has for its object the economizing of mill bands or
lists in spinning and twisting frames, as well as time, during the

page_text: operation of "doffing" owing to the construction of the flyer and
spindle afterwards described.
It is customary in the present system of "doffing" and " refilling,"
for the minder to take the mill band out of the wharve and then impart
a rotary motion with the one hand to the spindle, whilst holding the
flyer with the other, thus disconnecting the two for the purpose of
"doffing" and "refilling." This process injures the band and also
slackens it and occupies considerable time. To obviate these defects
we use a double-threaded screw upon the upper end of the spindle,
with a plain part above and below it. The flyer has a corresponding
screw in the higher part of its head, but is plain in the lower part.
The screw being double the flyer is sooner taken off; the operator by
touching the flyer shoulder towards the left hand for spinning, or
towards the right hand for twisting, releases the screw; the flyer then
only requires to be lifted off, and after the exchange of the full bobbin
for the empty one the flyer is placed on the spindle, and it is not
necessary to screw it down, but the frame being set in motion the flyer
finds its seat without flying off, in consequence of the plain parts referred
to on the spindle upper immediately above and below the screw thread.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Pickles, Edward Ramsbottom, Samuel
Haggas, Samuel Foulds, Joseph Shackleton, and William Berry
in the Great Seal Patent Office on the 11th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PICKLES, EDWARD RAMSBOTTOM, SAMUEL HAGGAS, SAMUEL FOULDS,
JOSEPH SHACKLETON, all of Bingley, in the County of York, and WILLIAM
BERRY, of Bradford, also in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of December, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Pickles, Edward Rams-
bottom, Samuel Haggas, Samuel Foulds, Joseph Shackleton, and William
Berry, Her special licence that we, the said John Pickles, Edward
Ramsbottom, Samuel Haggas, Samuel Foulds, Joseph Shackleton, and

page_text: William Berry, our executors, administrators, and assigns, or such others
as we, the said John Pickles, Edward Ramsbottom, Samuel Haggas,
Samuel Foulds, Joseph Shackleton, and William Berry, our executors,
administrators and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN SPINNING AND
TWISTING FRAMES," upon the condition (amongst others) that we, the said
John Pickles, Edward Rainsbottom, Samuel Haggas, Samuel Foulds,
Joseph Shackleton, and William Berry, our executors or administrators,
by an instrument in writing under our, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said John Pickles, Edward Ramsbottom,
Samuel Haggas, Samuel Foulds, Joseph Shackleton, and William Berry,
do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to
the Sheet of Drawings hereunto annexed, and to the letters and
figures marked thereon (that is to say) :-
In the present system of "doffing" and "refilling" the bobbins of
spinning and twisting frames it is customary for the minder to take
the mill band out of the wharve, and then impart a rotary motion to
the flyer spindle with the one hand whilst holding the flyer with the
other, thus disconnecting the two for the purpose of "doffing" and
"refilling" the bobbins. This process injures and slackens the band
and also occupies considerable time.
The object of our Invention is to curtail the time and labor required
in the operation of "doffing," and at same time to obviate the necessity
of taking the bands off the spindle pulleys, as above mentioned. This
we effect by means of the improved construction of flyer and spindle
herein-after described. Upon a small portion of the spindle top we
form a double threaded (or it may be a treble or quadruple threaded)
screw, with a plain part above and below it. The flyer has a.

page_text: corresponding female screw tapped into the upper part of the head
or boss thereof, the lower part being plain to correspond with the plain
part below the screw on the spindle top before mentioned. This screw,
which is made left-handed as usual for the spindles of spinning frames,
and right handed for twisting frames, greatly accelerates the discon-
nection of the flyer from the spindle. We make the pitch of the screw
from one-eighth to one-quarter of an inch, and so that by giving a
slight touch to the shoulder of the flyer in the direction the spindle
runs it will release itself from the spindle in one turn of the screw or
thereabouts. When the bobbin is full and requires doffing the operator
unscrews the flyer from the spindle by slightly hitting the flyer shoulder
in the manner above mentioned; he then with one hand removes the
flyer together with the full bobbin, and with the other hand places an
empty bobbin on the spindle. The flyer is now replaced on the spindle
top, and being struck on the shoulder as before (the way the spindle
runs) a portion of the thread from the full bobbin which is still held
in the hand is wound on the empty one. The thread between the full
bobbin and the empty one is then broken, and the full bobbin being
placed on the peg to receive it the operation is completed. The flyers
do not require to be screwed down, but on the frame being started will
find their seats without flying off.
The same result may be attained by employing a treble or quadruple
threaded screw on the spindle top, with plain parts above and below as
before described. With this construction of spindle top, together with
corresponding parts in the flyer head, the flyer has firm hold and sup-
port on the spindle, and will not fly off when the frame is suddenly
started or stopped.
Our Invention is illustrated in the accompanying Drawings, in which
Figure 1 represents a vertical section of a flyer and spindle constructed
according to our Invention.
a is the spindle which is provided with a double (or it may be a treble
or quadruple) threaded screw b formed on a small portion of the spindle
top and made left-handed, as seen, being intended for use in the spinning
frame. This screw b takes into a corresponding screw in the upper
part of the flyer head, the remaining portions c and d of the spindle
top being left plain as is likewise the lower portion of the flyer

page_text: head. Figure 2 is a section of a flyer and spindle provided with a
double (or it may be a treble or quadruple) threaded screw b, with plain
parts c and d as before; the screw 6 however in this case is right-
handed, being intended for use in a twisting frame. When the flyer,
Figure 1, is to be disconnected from the spindle it is struck on the
shoulder, as before described, one turn or thereabouts (and in flyer,
Figure 2, two turns or thereabout) being sufficient to bring it to the
position shown in red lines, when it only requires to be lifted off the
spindle top c. After an empty bobbin has been exchanged for a full
one, in the manner before described, the flyer is simply placed on the
spindle top c in the red line position, it not being necessary to screw
it down as it finds its scat on the spindle shoulder immediately said
spindle is set in motion.
Having described the nature of our Invention, and the manner of
performing the same, we declare that what we claim as our Invention
to be protected by the herein-before in part recited Letters Patent
is the improved construction of flyer and spindle top for spinning and
twisting frames arranged and operating in the manner and for the
purpose specified.
In witness whereof, I, the said John Pickles, for myself and
on behalf of the said Edward Ramsbottom, Samuel Haggas,
Samuel Foulds, Joseph Shackleton, and William Berry, have
hereunto set my hand and seal, this Ninth day of June, in
the year of our Lord One thousand eight hundred and sixty-nine.
JOHN PICKLES. (L.S.)
