page_text: LETTERS PATENT to John Kerr M*Myn, of Blackburn, in the County
of Lancaster, Manager, and Thomas Taylorson, of the same Place,
Mechanic, for the Invention of "IMPROVEMENTS IN MULES FOR SPINNING
AND DOUBLING COTTON, WOOL, AND OTHER FIBROUS Materials.”
Sealed the 3rd November 1874, and dated the 3rd August 1874.
PROVISIONAL SPECIFICATION left by the said John Kerr M°Myn and
Thomas Taylorson at the Office of the Commissioners of Patents,
with their Petition, on the 3rd August 1874.
We, JOHN KERR MºMYN, of Blackburn, in the County of Lancaster,
Manager, and THOMAS TAYLORSON, of the same Place, Mechanic, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MULES FOR SPINNING AND DOUBLING COTTON, WOOL, AND OTHER FIBROUS
MATERIALS," to be as follows:-
-
This Invention relates to the "winding-on" motion in spinning and
doubling mules, and consists in an improved arrangement of parts for
regulating the position of the "nosing peg," which by pressing upon

page_text: tho "winding-on chain" at cach stretch or draw of the mule carriage
imparts to the spindle during the operation of winding on the yarn a
speed proportional to its gradually decreasing diameter or taper, tho
object of our Invention being to provide means whereby the tension of
the yarn may be more uniformly controlled than heretofore, and so
devised as to impart increased firmness to the "nose" of the cop by
increasing the tension of the yarn uniformly from any desired point prior
to the completion of the cop.

According to our Invention we employ a screw mounted in a suitablo
bracket, working in a direction at right angles to the quadrant arm to
which the bracket is attached. The screw, which is rotated by a ratchot
and pawl arrangement, passes transversely through the "nosing peg,'
which in our improved arrangement is constructed to answer the purpose
of a travelling nut. The end of the nosing peg opposite to that which
bears upon the winding-on chain, enters a guide slot running parallel 1
to the screw, and extends through it a short distance so as to form a
travelling projection. On the same side of the bracket as this projection
there is a lover (which we term the "cross lever") running in the same
direction as and parallel with the screw.
One end of this cross lever
works freely on a pin or stud, and the other engages with a swing lever
carrying the pawl which actuates the ratchet wheel. Attached to this
cross lever and at about right angles thereto there is another lever of such
a length that when the carriage is at the end of the stretch it will
extend below the faller rods. On the upper edge of the cross lover we
affix a plate or flange which projects inwardly or at right angles towards a
the screw, and rests on the top of the projection formed on one end of
tho travelling nut, this arrangement being designed to control tho lift of
the pawl on the ratchet wheel by arresting at a given point the down-
ward motion of the cross lever each time the carriage recedes. This
plate or flange is made shorter than the screw, and may be made a
adjustable longitudinally by means of a slot and one or more set screws.
The action of the apparatus is as follows:-At the beginning of the
cop the travelling nut, which also constitutes the nosing peg, is brought
to a position near the ratchet end of the screw. As the carriago.
approaches the end of each stretch or draw the faller rod will come in
contact with and push forward the lever depending from the cross lever,
thereby causing the latter to be lifted up and with it the pawl actuating

page_text: the ratchet wheel. As soon as the carriage recedes the cross lever will
return to its former position, being arrested in its downward motion by
the flange which projects from its upper edge coming in contact with
the projection on the travelling nut. By the time the bottom of the
cop has been formed, the nosing peg having been moved forward upon
the screw at each stretch of the carriage will begin to press upon the
winding-on chain, and will continue to increase its pressure uniformly
at each succeeding stretch of the carriage until the projection on the
travelling nut has advanced to a point beyond the end of the flange on
the cross lever, when the latter having no longer the travelling projec-
tion to arrest its downward motion will descend still lower, thereby
causing the pawl carried by the swing lever with which the cross lever
engages to take up a greater number of teeth in the ratchet wheel. The
advance of the nosing peg will thereupon be accelerated, and its pressure
upon the winding-on chain increased, thereby augmenting the tension of
the yarn during the operation of completing or "nosing" the cop. To
determine the number of teeth on the ratchet wheel to be "taken up ”.
during the "nosing" of the cop we regulate the lift of the cross lever by
an adjustable stop placed below it. The lever depending from the cross
lever is also adjustable, so that it may be pushed forward by the faller
rod any convenient distance to correspond with the speed at which it
may be found requisite to advanco the nosing peg. When a new “set”.
has to be commenced the travelling nut and nosing peg aro brought back
to their original position on the screw, suitable provision being made to
ensure the nosing peg always starting from the samo point on tho
screw.

others as wo, the said John Kerr MºMyn and Thomas Taylorson, our
executors, administrators, and assigns, should at any time agree with
and no others, from time to time and at times all thereafter during
the term therein expressed, should and lawfully might make, usė,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MULES FOR SPINNING AND DOUBLING COTTON, WOOL, AND
OTHER FIBROUS MALERIALS," upon the condition (amongst others) that we,
the said John Kerr M°Myn and Thomas Taylorson, our executors or
administrators, 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 John Kerr MoMyn and Thomas
Taylorson, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described.
and ascertained in and by the following statement thereof, reference
being had to the accompanying Drawings and the letters and figures
marked thereon (that is to say):-
This Invention relates to the "winding-on" motion in spinning and
doubling mules, and consists in an improved arrangement of parts for
regulating the position of the "nosing peg," which by pressing upon tho
"winding-on chain" at each stretch or draw of the mule carriage
imparts to the spindle during the operation of winding on the yarn a
speed proportional to its gradually decreasing diameter or taper, the
object of our Invention being to provide means, whereby the tension of
the yarn may be more uniformly controlled than heretoforo, and so

page_text: devised as to impart increased firmness to the "nose" of the cop by
increasing the tension of the yarn uniformly from any desired point
prior to the completion of the cop.
According to our Invention we employ a screw mounted in a suitable
bracket working in a direction at right angles to the quadrant arm to
which the bracket is attached. The screw which is rotated by a ratchet
and pawl arrangement passes transversely through the "nosing peg,"
which in our improved arrangement is constructed to answer the purpose
of a travelling nut. The end of the nosing peg opposite to that which
bears upon the winding-on chain enters a guide slot running parallel to
the screw, and extends through it a short distance so as to form a
travelling projection. On the same side of the bracket as this projection
there is a lever (which we term the "cross lever") running in the same
direction as, and parallel with the screw. One end of this cross lever
works freely on a pin or stud, and the other engages with a swing lever
carrying the pawl which actuates the ratchet wheel. Attached to this
cross lever and at about right angles thereto there is another lever of
such a length that when the carriage is at the end of the stretch it will
extend below the faller rod. On the upper edge of the cross lever we
affix a plate or flange which projects inwardly or at right angles towards
the screw, and rests on the top of the projection formed on one end of
the travelling nut, this arrangement being designed to control the lift
of the pawl on the ratchet wheel by arresting at a given point the down-
ward motion of the cross lever each time the carriage recedes. This
plate or flange is made shorter than the screw, and may be made
adjustable longitudinally by means of a slot and one or more set
Screws.

page_text: Figs. 4 and 5 are side and end views respectively of our improved
apparatus, and Fig. 6 shows more clearly the construction of the "nosing
peg," as arranged for the
purposes of our Invention.
The same letters of reference are applied to like parts in all the
views.
In Figs. 1 and 3 A represents a portion of the framing of a mule
headstock, and B the arm of a quadrant to the upper end whereof is
attached our improved apparatus, which in these two Figures is shown
affixed to an extra bracket a slotted to allow of more ready adjustment of
the position of the apparatus relatively to the winding-on chain C. In
Fig. 1, the apparatus is shewn with the front faller rod 6 nearly touching
the lever (herein-after referred to as the depending lever). In Fig. 2,
the depending lever c is shewn in the position which obtains when it
has been pushed backwards, and has thereby lifted the cross lover d and
with it the swing lever e carrying the pawl ƒ which actuates the ratchet
wheel g
In Fig. 4 are shown more distinctively the details of our improved
apparatus. is the screw mounted in a bracket D; i, that portion of
the nosing peg which bears on the winding-on chain; j, an enlargement
or put through which the screw works; k, the guide slot in which the
nosing peg fits casily; 7, the other end of the nosing peg forming a
travelling projection; m, the flange (shewn by dotted lines in Fig. 4),
which rests upon the travelling projection 1, acting as a stop to arrest
the downward motion of the cross lever during the formation of a certain
portion of the cop. This flango or plate may be made adjustable
longitudinally by making it separate from the cross lever, and fastening
it by means of set screws passing through clongated holes; n, the pin or
stud on which the cross lever d works radially; o is a handle for the
purpose of winding the nosing peg to and fro upon the screw when
necessary; p is the adjustable stop under the cross lever, and on to
which the lower side of the cross lover falls by the lever's own weight
when the travelling projection is in the position shewn in Fig. 4. By
raising or lowering this adjustable stop the number of teeth of the ratchet
wheel to be taken up by the pawl during the "nosing" or completing of
the cop may be easily regulated; q is a device for the prevention of
breakage of any portion of the apparatus in the event of the spinner in

page_text: charge of the mule at the commencement of a set neglecting to bring
back the nosing. peg to the end of the screw nearest the ratchet wheel.
In Fig. 5, a portion of this device q is left out, so that other constructive
details may be more clearly seen. The projection if allowed to press
upon the upper portion of the projecting device q would force it back
until the cross lever would be raised, and the depending lever moved
backwards out of the reach of the faller rod, thereby putting the
apparatus out of action. The incline r at the end of the flange m
answers the double purpose of graduating the increase in the number of
teeth taken whilst the level portion of the flange rests upon the pro-
jection, and until the cross. lever drops to the stop p, and of allowing
the projection when the nosing peg is being drawn back to enter
underneath the flange without the necessity of lifting the cross lever by
hand.
:
The action of the apparatus is as follows:-At the beginning of the
cop the travelling nut which constitutes the nosing pog (i, j, l,) is
brought to a position near the ratchet end of the screw. As the carriago
approaches the end of each stretch or draw the faller rod will come in
contact with and push forward the lever c depending from the cross
lever d, thereby causing the latter to be lifted up and with it the pawl f
actuating the ratchet wheel g. As soon as the carriage recedes the cross
lover & will return to its former position, being arrested in its downward
motion by the flange m which projects from its upper edge coming in
contact with the projection on tho travelling nut (i, j,,). By the timo
the bottom of the cop has been formed, the nosing peg i having been
moved forward. upon the screw h at each stretch of the carriage - will
begin to press upon the winding-on chain C, and will continue to increaso
its pressure.uniformly at each succeeding stretch of the carriage until
the projection on the travelling nut has advanced to a point beyond the
end of the flange m on the cross lever, when the latter having no longer
the projection: to arrest its downward motion will descend still lower,
thereby causing the pawlf carried by the swing lever e, with which the
cross lever d engages, to take up a greater number of teeth in the
ratchet wheel g. The advance of the nosing peg i will thereupon be
accelerated, and its pressure upon the winding-on-chain C´increased so as
to augment the tension of the yarn during-the-operation of completing
or nosing the cop. The lever depending from the cross lover is also

page_text: adjustable, so that it may be pushed forward by the faller rod any con-
venient distance. At the commencement of a fresh "set" the nosing
peg will have to be wound back upon the screw by means of the
handle o until it reaches the ratchet end of the screw.
Having described the nature of the said Invention and the manner
of performing it, we wish it to be understood that wo do not limit our-
selves to the precise details illustrated in the accompanying Sheet of
Drawings, as they may evidently be modified to suit circumstances
without departing from the distinctive character of our Invention. We
are aware it is not new to apply a screw and a travelling nosing peg to 1
the end of a mule quadrant, and that arrangements have been devised
for imparting motion to a screw so applied, but the motion so imparted
in the arrangements we are acquainted with has been either uniform or
the speed of the screw has been increased gradually, whereas by our
plan wo are enabled to accelerate the speed of the screw and so to 1
increase the tension of the yarn exactly as and when required. We do not
claim as of our Invention or the exclusive use of the several mechanical
parts herein-before described or referred to, except when the same are
used in and for the purposes of our said Invention, but what we consider
to be novel and original, and therefore claim as the Invention secured
to us by the herein-before in part recited Letters Patent is as follows

page_text: 3rdly. The combination of parts constituting the improved apparatus,
constructed, arranged, and operating as herein-before described and
illustrated in the accompanying Sheet of Drawings, for the purpose
specified.
In witness whereof, we, the said John Kerr M'Myn and Thomas
Taylorson, have hereunto set our hands and seals, this Thirtieth
day of January, in the year of our Lord One thousand eight
hundred and seventy-five.
