IMPROVEMENTS IN MACHINERY FOR WINDING SEWING THREAD OF COTTON,
LINEN, OR SILK."
This Invention relates to improved machinery designed for winding sewing thread
upon bobbins directly from the thread polishing machinery, but which is also
applicable for winding the thread off beams or otherwise.
In the improved machinery the parts are carried by a framing having sides which
are reversely inclined to the longitudinal, vertical, and central plane of the machine,
both in plan and in transverse vertical section, and the frame is placed with its
longitudinal central plane in the continuation of that of the polishing machine.
The threads from the polishing machine pass one half to either side of the winding
machine, and the bobbins are so situated that the threads reach them in the most
direct manner and without interfering with each other, whilst the entire arrange-
inent is extremely compact.
The bobbins are placed on spindles which in one modification are fixed on rails
and are driven by means of pulleys loose on the spindles and actuated by cords
from drums occupying the centre of the machine. The rails carrying the spindles
are fixed in horizontal positions with their front ends, which are nearest the
polishing machine, nearer to the centre of the winding machine than their other
ends. There are six or other convenient number of rails at each side, and each rail
above the bottom one is nearer the centre of the machine than the one below it.
The spindles are fixed to the rails so that their upper ends incline outwards,
which prevents the different rows from interfering with each other, and makes the
putting on and off of the bobbins more convenient. The driving drums are slightly
inclined, their back ends being higher, so that the driving bands may pass properly
to all the spindles.
The drums may be driven by worm and worm wheel gearing, or by bevil wheel

page_text: gearing at one end of the frame, and a pair of cone pulleys is introduced in the
driving details to admit of the speed of the winding machinery being varied to suit
that of the polishing machinery or to suit the varying quantity of thread on the
bobbing.
The traverse guides are upon horizontal bars, on which they are by preference
adjustable by screws, and the traverse bars form part of two frames, one on each
side of the machine, each frame being guided so as to move parallel to the spindles
on its side of the machine. Each traverse frame is suspended by chains from
pulleys on a horizontal shaft at the top of the machine, and the two shafts are
moved by means of the usual heart cam traverse motion. .'

IMPROVEMENTS IN MACHINERY FOR WINDING SEWING THREAD OF COTTON,
LINEN, OR SILK."
My said Invention relates to improved machinery designed for winding sewing
thread upon bobbins directly from the thread polishing machinery, but which is
also applicable for winding the thread off beams or otherwise.
In the improved machinery the parts are carried by a framing having sides
which are reversely inclined to the longitudinal vertical and central plane of the
machine, both in plan and in transverse vertical section. The bobbins, which are
so situated that the threads reach them in the most direct manner and without
interfering with each other, are placed on spindles fixed on rails, which are fixed in
horizontal positions with their front ends nearer to the centre of the machine than
their other ends, and the spindles are fixed to the rails so that their upper ends
incline outwards. The traverse guides are upon horizontal bars which form part of
two frames guided so as to move parallel to the spindles.
And in order that my said Invention and the manner of performing the same
may be properly understood, I hereunto append two Sheets of explanatory
Drawings, to be herein-after referred to, and representing a thread winding
machine embodying my improvements. In these Drawings the same reference
numerals are used to mark the same or like parts wherever they are repeated.
Figure 1 on Sheet 1 of the Drawings is a plan; Figure 2 on Sheet 2 is an
end elevation; and Figure 3 is a side elevation of one modification of my improved
thread winding machine.
The framing of the machine consists of three transverse vertical standards 1, 2, 3,
connected by horizontal rails 4, and is placed with its longitudinal central plane in
the continuation of that of the polishing machine.
The threads 5 from guide rollers 6 of the polishing machine, or it might be from
a beam, pass one half to either of the winding machine and bobbins 7, a few only
of which are shown on one side in Figures 1 and 3, are placed on spindles S fixed
on the rails 4, and are driven by means of pulleys 9 loose on the spindles. The
pulleys 9 (shown in Figure 4 on a larger scale) are actuated by cords 10 from
drums 11 supported by their bearing spindles in the two end standards 1, 3, and
occupying the centre of the machine. The rails 4 carrying the spindles 8 are
fixed in horizontal positions with their front ends which are nearest the polishing
machine nearer to the centre of the winding machine than their other ends. There
are six rails 4 at each side, but any other convenient number might be used, and
each rail above the bottom one is nearer the centre of the machine than the one
below it.
The spindles 8 are fixed to the rails 4 so that their upper ends incline outwards,
which prevents the different rows from interfering with each other, and makes the

page_text: putting on and off of the bobbins 7 more convenient. The driving drums 11 are
slightly inclined, their back ends being higher, so that the driving bands 10 may
pass properly to all the pulleys 9.
The drums 11 are driven by worm wheels 12 in gear with worms 13 on a vertical
shaft 14 at one end of the frame, and the shaft 14 derives its motion from a hori-
zontal shaft 15 through bevil gearing 16. The shaft 15 is driven by a belt 17
passing over a pulley on that shaft and over a second pulley on a shaft carrying a
cone pulley 18, and to this cone pulley 18 the motion of a second cone pulley
actuated by the driving details of the polishing machine (and not shown in the
Drawings) is transferred by a belt 19. The introduction of the cone pulleys admits
of the speed of the winding machinery being varied to suit that of the polishing
machinery or to suit the varying quantity of thread on the bobbins.
Traverse guides 20 for distributing the thread on the bobbins (shown also
separately in Figure 5) are held upon horizontal bars 21, on which they are by
preference adjustable by screws 22, and the traverse bars 21 form part of two
frames 23, one on each side of the machine. Each frame 23 is guided by rods 24
fixed to it and passing through guide pieces 25 on the standards 1, 3, so as to adinit
of the movement of the frame parallel to the spindles on its side of the machine,
and each traverse frame 23 is suspended by chains 26 from pulleys 27 fixed on a
horizontal shaft 28 at the top of the machine. The two shafts 28, which have fixed
on each of them a pulley 29, are moved by means of a heart cam 30 acting on
levers 31, to which the pulleys 29 are connected by chains 32, and the cam 30 is
actuated through interposed worm gearing from the vertical shaft 14. A guide
bar 33 for each horizontal row of bobbins is fixed to the front end of the traverse
frame 23, and is fitted with vertical pins to separate the individual threads of each
row in passing to the traverse guides 20.
Having thus particularly described my said Invention, and the manner of per-
formning the same, I have to state that I do not restrict myself to the precise details
herein described or delineated, but that what I believe to be novel and original,
and claim as the Invention secured to me by the herein-before in part recited
Letters Patent is,―
.
1. The arranging or combining together of parts to form a thread winding
machine, substantially in the improved manner herein described and delineated.
2. The combining of the inclined spindles on rails which are oblique in plan,
with traverse guide frames moving in inclined guides parallel to the spindles, as
and for the purposes herein-before described.
3. The fixing of the spindles on the rails, and driving the bobbins by means of
pulleys loose on the spindles, and engaging with the bobbins, as herein-before
described.
In witness whereof, I, the said William McGee, have have hereunto set my
hand and seal, this Twenty-eighth day of July, in the year of our Lord
One thousand eight hundred and seventy-six.
