Improvements in Winding Thread and in Apparatus therefor.
We, GEORGE WORSLEY, of 'Beech. Lawn, Hat Manufacturer, ALBERT ERNEST
WORSLEY, of 22, Audenshaw Road, Commercial Traveller, both of Audenshaw,
and FRANCIS CREE, Senior, of Broomstair House, Hyde Road, Denton, Mechanic,
all in the County of Lancaster, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved method of and apparatus for winding
sewing thread in the form of a long cylindrical cop with conical ends, for use-
in lock-switch sewing machines provided with revolving carriers for the under
or "lock" thread:
The improvement in winding thread for this purpose consists in winding it
in the form of a long cop formed of a series of cones super-posed so that one
end is formed an obtuse cone and the other end a hollow cone. . The thread
from the hollow or butt" end is drawn through the middle of the cop and is
delivered at the "nose" end. As the thread is drawn off, the cop remains of the
same diameter and solidity to the end diminishing gradually in length from the
rear end.
The machine consists principally of a headstock carrying a revolving spindle
holder, in combination with a reciprocating thread guide mounted on a carriage
sliding horizontally upon a bed-plate and actuated by means of a slowly revolving
screw. The spindle holder is fitted with a small grooved pulley driven rapidly
by an endless band from a larger pulley which is actuated by hand, foot, or other
power. The spindle is tapered and its butt-end fits tightly in the holder its
extreme end being steadied by a spring support. This end is fitted with a loose
cone between which and the thinner end of the spindle the end of the thread
is held tight. The butt-end is also provided with a cone. The bed-plate extends
longitudinally below the spindle and the carriage which slides along the bed-
plate supports the thread-guide, which is in the form of a lever moving to and
fro horizontally over the spindle. This thread guide is moved horizontally in
one direction by means of a rocking bar acting against a finger and in the reverse
direction by means of a coiled spring. The rocking bar is actuated by a lever
which is held by a spring against a double cam or "former" driven by an endless
band from the headstock spindle carrier.
The screw for traversing the thread-guide carriage is caused to make a portion
of a revolution intermittently by means of a ratchet or "grip" motion connected
to a lever actuated by an excentric or cam mounted on the spindle carrier, and the
working surface of this excentric or cam is made conical so that by shifting it

page_text: endwise on its spindle by means of a regulating screw the diameter of the cop
may be varied.
It will be evident that the machine may be made to work in a vertical instead
of a horizontal position, and that as a further modification the thread guide
carrier may remain fixed and the endwise movement as the winding on of the cop
progresses may be given to the spindle by means of a screw so as to produce the
same effect.

Improvements in Winding Thread and in Apparatus therefor.
We, GEORGE WORSLEY, of Beech Lawn, Hat Manufacturer, ALBERT ERNEST
WORSLEY, of 22, Audenshaw Road, Commercial Traveller, both of Audenshaw,
and FRANCIS CREE, Senior, of Broomstair House, Hyde Road, Denton, Mechanic,
all in the County of Lancaster, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention relates to an improved method of and apparatus for winding
sewing thread in the form of a long cylindrical cop with conical ends suitable for
use in lock-stitch sewing machines which are provided with revolving carriers
for the under or lock" thread.
**
The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a longitudinal section of a long cylindrical cop of
sewing thread with conical ends wound in accordance with our invention and
Fig. 2 is a similar view showing the same bent or curved into a circular form to
fit into the revolving carrier of the lock-stitch sewing machine.
Fig. 3 is a side elevation of our improved apparatus for winding such cops of
sewing thread.
Fig. 4 is a plan view of the same, and Figs. 5 and 6 are detached views herein-
after more particularly referred to.
The improvement in winding thread for the purposes of our invention consists
in winding the same in the form of a long cylindrical cop (see Fig. 1) built up
of a series of cones superposed so that one end of the cop forms an obtuse cone,
and the other end a reversed or hollow cone. The thread from the hollow or
" butt end bis drawn through the hollow centre of the cop, and is delivered
at the "nose" end a. As the thread is drawn off, the cop remains of the same
diameter and solidity to the end, but diminishes gradually in length from the
rear end as it is drawn off.
.

"
Another great advantage derived from this improved method of winding the
thread is that it enables a cop containing a very considerable length of sewing
thread (say from 1000 to 1,500 yards) to be used as the under or lock thread
of a sewing machine in a continuously revolving carrier without any tendency
to cause the thread to "snarl" or "kink" by overtwisting.
The improved machine by which we propose to wind the sewing thread in
this manner consists principally of a headstock c (see Figs. 3 and 4) carrying a

page_text: revolving spindle holder d, in combination with a reciprocating thread guide e
mounted on a carriage f sliding horizontally upon the bed-plate gand actuated
by means of a slowly revolving screw h. The thread guide e may be fitted with
any ordinary tension device.
The spindle-holder d is fitted with a small grooved pulley i driven rapidly by
an endless band from a larger pulley which is actuated by foot, hand, or other.
power,
The spindle is tapered and its "butt" end fits tightly in the holder d its
extreme end being steadied by a spring-support 1.
This end is fitted with a loose cone m between which and the thinner end of
the spindle the end of the thread to be wound is held tight. The butt end of
the spindle is also provided with a cone n.
The bed-plate y extends longitudinally below the spindle k, and the carriage f
which slides along the bed-plate g supports the thread guide e which is in the
form of a lever moving rapidly to and fro in a horizontal direction over the
spindle k.
This thread guide e is moved horizontally in one direction by means of a rock-
ing-bar acting against a finger p, and in the reverse direction by means of a
coiled spring :
The rocking bar is actuated by a lever (see also end view Fig. 6) which is
held by the spring 7 (Figs. 3 and 4) against a double cam or former s driven by
an endless band from the headstock spindle carrier d.
The screw for traversing the thread-guide carriage f is caused to make a
portion of a revolution intermittently by means of a jointed grip-motion u (see
also end view Fig. 5) connected to a lever actuated by an excentric or cam te
mounted on the spindle carrier d, and the working surface of this excentric or
cam is made conical (as shown at Fig. 4) so that by shifting it endwise on its
spindle by means of the regulating screw the diameter of the cop may be
varied.
The half nut (see Fig. 3) which works on the screw is hinged to the car-
riage so that it can be lifted out of gear with the screw when it is desired to
move the carriage by hand to the extreme right so as to commence winding a
fresh cop. It will be evident that the slowly progressive motion of the carriage
combined with the rapid to-and-fro motion of the thread guide will cause the
thread to be wound on the spindle in a series of superposed cones from end to
end in the form shown at Fig. 1.
It will be evident that instead of giving this slow endwise progressive motion
to. the reciprocating thread-guide carriage the latter may be stationary and the
slow endwise progressive motion be imparted to the revolving spindle carrier
which will produce the same effect.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The improvement in winding thread for use in sewing machines which con-
sists in winding such thread in the form of a long cylindrical cop with a conical
nose and a hollow conical base substantially in the manner and for the purposes
described.
2. The improved apparatus for winding thread in the form of cops for use in
sewing machines consisting mainly in the combination with a revolving spindle
of a rapidly reciprocating thread guide mounted on a sliding carriage to which
(or to the revolving spindle) a slow endwise motion is given by means of a screw
or equivalent device substantially as hereinbefore described and illustrated by
the drawings annexed.
3. In apparatus for winding thread in the form of cops for use in sewing
machines. the combination with a revolving spindle, of a thread-guide e mounted
on a sliding carriage f; means for imparting a rapidly reciprocating motion to

motion to the said carriage f substantially as hereinbefore described and illus-
trated by the drawings annexed.
4. The improved cop substantially as hereinbefore described.
