LETTERS PATENT to Edmund Ashworth of Bolton-le-Moors in the County
of Lancaster Thread Manufacturer for an invention of IMPROVEMENTS IN
YARN WINDING MACHINES
"
PROVISIONAL SPECIFICATION left by the said Edmund Ashworth at the
Office of the Commissioners of Patents on the 24th May 1882.
EDMUND ASHWORTH of Bolton-le-Moors in the County of Lancaster Thread
Manufacturer "IMPROVEMENTS IN YARN WINDING MACHINES
"
My Invention relates to the yarn-winding machinery constructed in accordance
with an Invention for which Letters Patent bearing date the seventeenth of
August in the year one thousand eight hundred and eighty and numbered 3331
were granted to William Knowles. In the said Patent Machinery the yarn is
wound with a quick traverse of the guides so that the layers cross each other the
result being a cohering cylinder of wound yarn which can be transported from
place to place without requiring the support of a bobbin. The object of my
Invention is to increase the stability of the coiled yarn and this I effect by
winding the yarn into the form of a cylinder with coned or beveled ends. The
traverse of the yarn guides is reduced as the winding on proceeds. The said
traverse is effected by means of a cam which acts upon a lever which gives motion
to the yarn guides.
I transmit the movement to the yarn guides through a carriage or sliding block
or part which is mounted upon the said lever. A screw engages with the said
carriage or sliding block. The said screw is provided with a ratchet-wheel with
which engages a pawl which is carried by the fixed stud upon which the said lever
vibrates or the said pawl is mounted upon a lever which is acted upon by a fixed
part as the first named lever vibrates. As the actuating lever vibrates the screw
receives an intermittent revolving movement which gradually brings the connection
of the sliding carriage or block with the part which carries the yarn guides nearer
to the fulcrum of the said lever whereby the traverse of the yarn guides is lessened
as the building up of the coiled yarn proceeds.

IMPROVEMENTS IN YARN WINDING MACHINES."
"
My Invention relates to the yarn winding machinery.constructed in accordance
with an Invention for which Letters Patent bearing date the seventeenth day of
August in the year one thousand eight hundred and eighty and numbered three
thousand three hundred and one, were granted to William Knowles. In the said
Patent machinery the yarn is wound with a quick traverse of the guides so that
the layers cross each other the result being a cohering cylinder of wound yarn
which can be transported from place to place without requiring the support of a
bobbin. The object of my Invention is to increase the stability of the coiled yarn
and this I effect by winding the yarn into the form of a cylinder with coned or
bevelled ends. The traverse of the yarn guides is reduced as the winding on
proceeds. The said traverse is effected by means of a cam which acts upon a lever
which gives motion to the yarn guides. I transmit the movement to the yarn
guides through a carriage or sliding block or part which is mounted upon the said
lever. A screw engages with the said carriage or sliding block. As the actuating
lever vibrates the screw receives an intermittent revolving movement which
gradually brings the connection of the sliding carriage or block with the part
which carries the yarn guides nearer to the fulcrum of the said lever whereby
the traverse of the yarn guides is lessened as the building up of the coiled yarn
proceeds.
In order that my Invention may be fully understood I have attached hereunto
a sheet of drawings made to a scale of about three inches to the foot and marked
with letters of reference. In the said drawings Fig: represents a front elevation
of one end of the improved winding machine, Fig: 2 being a cross sectional view
taken on the line *. Fig: 3 is a plan of the mechanisim which effects the shaping
of the cylindrical coil of yarn. In the said Figs a is one of the coils of yarn which
is unwound from a bobbin b as is usual and c is one of the yarn guides which are
carried by a guide bar d which is caused to traverse quickly to and fro. The yarn
is wound upon plain tubes not having flanges and the coils of yarn are caused to
cohere so that the coiled yarn will bear handling by reason of the quick traverse
of the yarn guides which causes the coils of yarn to cross each other as indicated
by the dotted lines in Fig: 1 and as set forth in the specification describing the
Invention of the said William Knowles. The coiling is effected by means of the
revolving shaft e which extends from one end of the machine to the other and
drives the tube and the coiled yarn by contact as is usual. A corresponding
shaft e¹ on the other side of the machine is connected by gearing with a spur
wheelf which is fixed upon the same shaft as a grooved cam g. The cam imparts
a vibrating movement to a double-ended lever h which is mounted upon a central
fulcrum studi which is secured to a fixed bracket j. Fig 4 is an end view of
these parts. An anti-friction bowl mounted upon a stud at one end of the lever
enters the groove in the cam. The said lever is planed to receive two carriages
k, k, which are fitted to slide upon the two arms of the lever. Each carriage
carries a stud which enters a slot in an arm which is secured to the yarn guide
bar d as seen most clearly in Fig: 3. As the machine illustrated is a double-
sided machine there are two guide bars one on each side of the machine. It will
be seen that when the lever h vibrates upon its fulcrum by reason of the action of

page_text: the cam the two yarn guide bars are caused to traverse to and fro whereby the
yarn is coiled in layers upon the tubes. Each of the two carriages k, k, or a nut
thereon engages with a right and left hand screw shaft which is carried by the
lever. Upon this screw shaft is fixed a worm wheel m with which gears a worm
which is upon one end of a cross shaft which is fitted to revolve in a bearing
block n which is fixed to the centre of the lever h. Upon the other end of the
said cross shaft is secured a ratchet wheel o with which engages a pawl p which is
mounted upon a stud which is carried by a bracket which is fixed to the framing.
It will be seen that in consequence of the ratchet wheel projecting some distance
on one side beyond the fulcrum of the lever the said ratchet wheel will move to
and fro as the lever vibrates and that as the pawl is stationary this to and fro
movement of the ratchet wheel will cause it to receive an intermittent rotating
movement which is imparted in a lesser degree by the worm and wheel to the
screw shaft. This rotation of the screw shaft causes the carriages to slide upon
the lever towards the centre of motion of the lever whereby the studs which act
upon the yarn guide bars are caused to vibrate in smaller arcs. At the commence-
ment of the winding upon the tube the screw shaft is turned by means of a handle
which fits upon either of the squared ends of the shaft until the carriages k, k are
moved sufficiently away from the axis of the lever. As the winding on proceeds
the carriages are gradually moved towards the axis of the lever whereby the
traverse of the yarn guides is gradually dereased as the yarn becomes coiled upon
the tubes the effect being that the yarn becomes wound upon each tube in the
form of a cylinder having coned ends. I do not confine myself to the double
armed lever fitted with two carriages as for example each side of the machine
might have a lever fitted with one carriage but I prefer the arrangement
illustrated
Having now described and more particularly ascertained the nature of my said
Invention and the manner of carrying the same into practical effect I would
observe in conclusion that what I claim is :-
First, the apparatus for regulating the winding of yarn upon tubes so as to
cause the yarn to be wound upon each tube into the form of a cylinder with coned
ends substantially as set forth and indicated in the drawings
Secondly the double armed vibrating lever carrying studs or parts which cause
the yarn guide bars to traverse and the rotating screw shaft for shifting the said
studs or parts nearer to the axis of the vibrating lever whereby the traverse of the
yarn guide bars is lessened substantially as and for the purpose set forth.
And lastly the lever h, the carriages k, k acting upon the yarn guide bars, the
screw shaft receiving movement by means of the ratchet wheel o and pawl p
substantially as set forth and indicated.
In witness whereof I the said Edmund Ashworth have hereunto set my
hand and seal this twenty-second day of November in the year of our
Lord one thousand eight hundred and eighty-two
