LETTERS PATENT to James King, of Rochdale, in the County of Lan-
caster, Cotton Spinner, and John Sutcliffe, of the same Place, Overlooker,
for the invention of "CERTAIN IMPROVEMENTS IN UB APPLICABLE TO MACHINED
D"
Sealed the 4th March 1862, and dated the 14th September 1861.
PROVISIONAL SPECIFICATION left by the said James King and John
Sutcliffe at the Office of the Commissioners of Patents, with their
Petition, on the 14th September 1861.
We, JAMES KING, of Rochdale, in the County of Lancaster, Cotton Spinner,
and JOHN SUTCLIFFE, of the same Place, Overlooker, do hereby declare the
nature of the said Invention for "CERTAIN IMPROVEMENTS IN OR APPLICABLE
TO MACHINES FOR SPINNING AND DOUBLING," to be as follows:-
The object of our Invention is to facilitate the removal of the full cops from
the spindles of mules or other machines for spinning, our improvements being
particularly applicable to those spindles to which thin metal cop tubes are
applied.
In performing our Invention we make use of straightedges or rulers,
having recesses fitting on the spindles, and hinged on centres fixed on that
side of the spindle nearest the roller beam. The spindles are furnished by
preference with buttons, and the rulers act on these buttons to raise the cops.

page_text: The rulers are provided with handles or other apparatus, by acting on which
the cops are forced up the spindles.
Another part of our Invention consists in regulating the position of the nut
of the winding-on chain by a rod with notches. This rod bears on a pulley
fixed to a bevil pinion mounted on the stud of the radial arm; the catch for
taking into the notches is connected to both the faller shafts. When the yarn
is too tight, the catch is lowered, so as to act on the notches, and at other
times the catch is held out of contact with the notches.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James King and John Sutcliffe in the Great Seal Patent
Ollice on the 13th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JAMES
KING, of Rochdale, in the County of Lancaster, Cotton Spinner, and Joun
SUTCLIPPE, of the same Place, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Ier Letters
Patent, bearing date the Fourteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Iler reign, did, for Flerself, Her heirs and successors, give and grant unto us,
the said James King and John Sutcliffe, Her special license that we, the
said James King and John Sutcliffe, our executors, administrators, and
assigns, or such others as we, the said James King and John Sutcliffe, 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 "CERTAIN IMPROVEMENTS IN OR APPLICABLE TO
MACHINES FOR SPINNING AND DOUBLING," upon the condition (amongst others)
that we, the said James King and John Sutcliffe, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of our or
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 James King and John Sutcliffe, do
hereby declare the nature of our said Invention, and in what manner the

page_text: same is to be performed to be particularly described and ascertained in and
by the following statement (that is to say):-
The nature of our Invention consists, first, in an improved arrangement of
parts for doffing or raising the full cops partially up the spindles of mules or
other machines for spinning and doubling.
Secondly, in an improved combination and arrangement of parts for
regulating the position of the nut on the screw of the radial arm (to which
one end of the winding-on chain is attached), according to the tension of
the yarn.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation of part of a self-acting mule to which our improve-
ments are applied; Fig. 2 is a detached view of the doffing bar.
a is the framing of the mule headstock; b, the carriage, running as usual
on the rails c; d, the spindles; e, the faller shaft; f, the counter-faller shaft;
g, the radial arm; h, the screw; h³, the nut; and h², the small pulley on the
fulcrum stud of the radial arm; these parts and all the others requisite to
complete the mule which are not shewn in the Drawing, and not particularly
referred to hereafter, are made in the usual manner. The improved arrange-
ment of parts for doffing the full cop consists of the straightedge or ruler i,
which is shown of sufficient length to doff 36 spindles simultaneously; but we
wish to remark that it may be increased or diminished in length, so as to act
on a greater or less number of cops. The ruler i is supported at each end and
in the centre in the bearings j, which are fixed on the bolster rail of the
carriage 6; the ruler i is provided with recesses corresponding to the spindles,
and with a handle k. When the cops are being built, the handle and ruler are
in the positions indicated by the full lines in Fig. 1, that is to say, the edge
of the ruler is resting on the bolster rail; but when the cops are completed
and ready for being doffed, the attendant presses down the handle k into the
position indicated by dotted lines, thereby raising the ruler i and bringing each
recess on to one of the spindles, the edges of the recesses are thus brought
against the buttons on to which the cop tubes rest, or else against the under
side of the conical cop tube on which the bottom of the cop is built; by this
means 36 or other convenient number of cops are raised simultaneously partly
up the spindles, ready for being taken off by hand in the usual manner, and
as the ruler i is placed behind the spindles, or between the spindles and the
roller beam, the parts are not in the way of the operator.
Our improved apparatus for regulating the position of the nut on the screw

page_text: of the radial arm consists of the following parts:-The winding-on strap
instead of being an endless strap, as usual, is now attached at each end to the
horizontal rod m which bears on the pulleys and h³; to this rod is fixed
three or other convenient number of catches marked m³, m³, and m³; to the
carriage bis hinged the pall n, which is connected by the chain n' to the faller
and counter-faller shafts e and f; when the yarn is too tight the extra tension
depresses the faller wires, and the pall n is lowered into the position indicated
by the dotted lines, so that when the carriage is running in the pall comes
against either of the catches m³, m³, or m³, and moves the rod m in the
direction of the arrow; this motion of the rod m is communicated by the
strap to the small pulley 3, and from it to the screw and nut h¹ of the
radial arm by bevel pinions in the usual manner, thus increasing the distance
of the nut from the fulcrum, and letting off more of the winding-on chain.
During the outward run of the carriage the stud of the pall n acting on the
projection m brings the rod m back to its original position. It is evident as
the catches m³, m³, and m³ are of different heights, that the pall n will come
in contact with either one or the other, according as the tension of the yarn
lowers the pall n more or less. When the bottom of the cop is built the
pall n is held above the catches on the rod m, consequently the carriage in
running in ceases to act on the catches until the set of cops is completed, after
which the nut h' is screwed back by hand to near the fulcrum of the radial
arm, and the operations are repeated as before.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim,-
First, the improved arrangement of the parts for doffing the full cops
from the spindles of machines for spinning and doubling, as shewn and
described.
Secondly, the improved combination of machinery for regulating the
winding-on motion, as shewn and described.
In witness whereof, I, the said John Sutcliffe, have bereto set my hand
and seal, this Twelfth day of March, in the year of our Lord One
thousand eight hundred and sixty-two.
JOHN SUTCLIFFE. (L.S.)
