IMPROVE- MENTS IN MULES FOR SPINNING AND DOUBLING
Year: 1866

page_text: LETTERS PATENT to John Warburton, Cotton Spinner, Peter Warburton,
Overlooker, and Smith Barnes, Operative Spinner, all of Haslingden,
in the County of Lancaster, for the Invention of "IMPROVEMENTS IN
Sealed the 17th July 1866, and dated the 3rd February 1866.
PROVISIONAL SPECIFICATION left by the said John Warburton, Peter
Warburton, and Smith Barnes at the Office of the Commissioners of
Patents, with their Petition, on the 3rd February 1866.
We, JOHN WARBURTON, Cotton Spinner, PETER WARBURTON, Overlooker,
and SMITH BARNES, Operative Spinner, all of Haslingden, in the County of
Lancaster, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MULES FOR SPINNING AND DOUBLING," to be as follows:-
Our Invention consists of a self-acting combination of parts for regulating or
governing the backing off or unwinding of the yarn on the spindles according
to the size and length of the cop.
In performing our Invention we connect to the faller shaft a slotted lever

page_text: in which is a screw acting on a sliding nut; to this nut is fixed or cast
a hook to which the backing-off chain is connected. The screw is turned
partly round at every stretch by a ratchet wheel and catch or other equivalents
to move the nut and hook gradually up the slot, or the point of connection
of the chain may be varied by other means. At the commencement of
forming a set of cops the nut is down and the greatest amount of backing
off is produced, but as the cop increases in length the backing off is pro-
portionately reduced by the moving of the nut up the screw; by this means
time is gained and the nose of the cop is kept tight, and the waste or injury
by snarls is avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Warburton, Peter Warburton, and Smith Barnes in
the Great Seal Patent Office on the 2nd August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WARBURTON, Cotton Spinner, PETER WARBURTON, Overlooker, and SMITH
BARNES, Operative Spinner, all of Haslingden, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of February, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the
said John Warburton, Peter Warburton, and Smith Barnes, Her special
license that we, the said John Warburton, Peter Warburton, and Smith
Barnes, our executors, administrators, and assigns, or such others as we
the said John Warburton, Peter Warburton, and Smith Barnes, 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 SELF-ACTING
MULES FOR SPINNING AND DOUBLING," upon the condition (amongst others)
that we, the said John Warburton, Peter Warburton, and Smith Barnes,
our executors or administrators, by an instrument in writing under our, or
their, or one of our or their hands and seals, should particularly describo
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

page_text: 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 Warburton, Peter Warburton,
and Smith Barnes, 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 (that is to say)
-
Our Invention consists of a self-acting combination of parts for regulating
or governing the backing off or unwinding of the yarn on the spindles according
to the size and length of the cop.
In performing our Invention we connect to the faller shaft a slotted lever
in which is a screw acting on a sliding nut, to this nut is fixed or cast a hook
to which the backing-off chain is connected. The screw is turned partly
round at every stretch by a ratchet wheel and catch or other equivalents to
move the nut and hook gradually up the slot, or the point of connection of
the chain may be varied by other means.
And in order that our Invention may be fully understood and readily
carried into operation we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is a front view, and Figure 2 a plan of our improved machinery
for regulating or governing the backing off or unwinding of the yarn on the
spindles. a is the faller shaft, and 6 the slotted lever fixed upon it by a
set screw or otherwise; the screw c revolves in bearings in the slotted lever b,
and on the screw c is the nut d to which is fixed or cast the hook e, and to
this hook is connected one end of the backing-off chain f, the other end being
attached as usual to the winding-on barrel. To the upper end of the screw c
is fixed the ratchet wheel g, and to a projection from the lever b is fixed a
stud for the retaining catch h taking into the teeth of the ratchet wheel g;
as the faller ascends after every stretch the ratchet wheel comes in contact
with a stud or catch fixed to the front of the headstock which moves the
ratchet wheel round for one tooth and gives a partial turn to the screw c,
At the commencement of
thereby slightly raising the nut d and hook e.
forming a set of cops the nut is down or about in
Drawing and the greatest amount of backing off is produced, but as the cop
increases in length the backing off is proportionately reduced by the moving
of the nut up the screw. By this means time is saved and the nose of the
cop is kept tight, and the waste or injury by snarls is avoided. The pitch of
the screw c and the number of teeth in the ratchet wheel ġ must be varied
according to the count of the yarn that is being spun or doubled.
the position shewn in the
Having thus stated the nature of our Invention, and described the manner

page_text: of performing the same, we declare that we claim the improved self-acting
combination of parts shewn and described for regulating or governing the
backing off according to the size and length of the cop, or any modification of
the same, whereby the point of connection of the backing-off chain is varied
it every stretch.
In witness whereof, we, the said John Warburton, Peter Warburton, and
Smith Barnes, have hereto set our hands and seals, this Thirty-first
day of July, One thousand eight hundred and sixty-six.
