Improvements in Yarn Winding Machinery.
We, JOHN DEMPSTER WHYTE, of 31, Lime Avenue, Urmston, near Manchester,
in the County of Lancaster, Engineer, and WHYTE'S PATENTS LIMITED, of 94,
King Street, Manchester, aforesaid, do hereby declare the nature of this inven-
tion to be as follows:-
Our said invention relates to yarn winding machinery and has reference to
improvements upon a former invention for which we have received Her Majesty's
Letters Patent No. 21992 of 1896.
Our improvements relate to the means of driving the spindles and cone cam
or the like used to traverse the yarn guide, and for lowering the spindles to
effect the building of the cops.
Under our present invention the whole of these movements are derived from
one shaft thus greatly simplifying the construction of the machine.
In carrying our invention into effect we provide a driving shaft disposed
centrally between the spindles at each side of the frame. Upon the driving shaft
we key a number of double grooved pulleys, one for each spindle. The sliding
wharve shown in the specification of our said former patent for driving the
spindle is duplicated one of which wharves however runs loosely upon the spindle
barrel or carrier. The driving pulley mounted upon the axis of the cone cam
or equivalent device for traversing the yarn guide is similarly duplicated, one
pulley being fast and the other loose upon the axis of the cone cam. The spindle
wharves and cam pullies are driven by means of bands from the double grooved
driving pulley mounted on the driving shaft. Instead of the double grooved
pullies a tin cylinder may be used.
We provide means whereby on the breakage of a thread the driving bands are
automatically shifted from the fast to the loose pullies so that the revolution
of the cone cam and spindle is stopped, and also simultaneously effect the stoppage
of the downward descent of the spindle.
Each thread is provided with a pivotted drop finger normally held out of the
path of a swinging finger operated by a shaft as in our former invention.
Pivotted to the drop finger is a bell crank lever, the other end of which is con-
nected to a vertical rod. The upper end of the rod is connected to a bell crank
lever carrying or operating a bell fork embracing the band driving the cone can,
and the lower end of the vertical rod operates a fork embracing the band driving
the spindle wharve, and at the same time turns a rock shaft mounted in suit-
able bearings. The spindles are lowered by means of a rack and pinion as
described in the specification of our said former patent but instead of driving
the pinions by means of friction discs we mount them loosely upon a countershaft
and drive such countershaft through a train of gearing, which is arranged to be
interchangeable, from the driving shaft.
To start and stop the pinion meshing with the rack we provide it with a
clutch the driving half of which is taken out of action by means of a yoke secured
to the rock shaft above mentioned.
On the breakage of a thread the drop finger falls and is pushed forward by

page_text: the reciprocating finger. The vertical rod is thus depressed by the bell crank
lever connected to the rod and the drop finger, and operates the forks so as to
shift the bands from the fast pulley, and wharve to the loose ones thus stopping
the revolution of the cone cam and spindle. At the same time the rock shaft
is operated to take the driving clutch half out of action and the pinion gearing
with the rack is thus stopped.
To start the machine after "piecing" the rock shaft is provided with a handle
which may be operated by the knee of the attendant so as to again bring the
clutch half into action and operate the vertical rod and belt forks to replace
simultaneously the bands upon the fast pulley and wharve.

Improvements in Yarn winding machinery.
We, JOHN DEMPSTER WHYTE, of 31, Lime Avenue, Urmston, near Manchester,
in the County of Lancaster, Engineer, and WHYTE'S PATENTS LIMITED, of 94,
King Street, Manchester, aforesaid, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement and accompanying drawings: -
-
Our said invention relates to yarn winding machinery and has reference to
improvements upon a former invention for which we have obtained Her Majesty's
Letters Patent No. 21992 of 1896.
Our present invention refers to improved means of driving the spindles and
cone cam, or its equivalent, used to traverse the yarn guide, and for lowering
the spindles to effect the building of the cops. We now arrange to derive all
these movements from one shaft thus greatly simplifying the construction of
the machine.
And in order that our invention may be distinctly understood we have attached
hereto four sheets of illustrative drawings to which we will now refer.
Fig. 1 of the drawings is an end elevation partly in section of the improved
yarn winding machine."
Fig. 2 is a sectional plan thereof.
Fig. 3 is a sectional elevation.
Fig. 4 is a side view of the frame and
Fig. 5 a detail view of one of the parts.
In caying our invention into effect we provide a central driving shaft a
mounted to revolve in bearings in the frame A of the machine and arrange that
the whole of the movements shall be obtained from this shaft. The shaft a
is disposed centrally between the spindles b any suitable number of which are
carried at each side of the machine. The shaft a is provided with a fast and
loose pulley
c c¹ whereby the shaft is driven from any suitable source of power
and stopped when required. Upon the driving shaft a is mounted a driving
cylinder d. The sliding wharve e shown in the specification of our said former
patent for driving the spindle 6 is duplicated one of which wharves el however
runs loosely upon the spindle barrel or carrier.
The driving pulley f mounted upon the axis of the cone cam g is also duplicated
a loose pulley f¹ being mounted on the axis of the cone cam 9. The spindle

page_text: wharves are driven by means of bands hand the cam pullies by means of bands i
from the cylinder d of the driving shaft a. The tension of the bands h is main-
tained by weights h¹ acting on pullies h² carried on pivotted forks h³.
Instead of a driving cylinder & we might provide the shaft a with a number of
double grooved pullies, one for each spindle, the double grooves accommodating
the driving bands hi. On the breakage of a thread means are provided whereby
the driving bands hi are automatically shifted from the fast wharve e and pulley f
to the loose ones el f¹ so that the revolution of the cone cam and spindle is stopped.
In addition we also simultaneously effect the stoppage of the downward descent
of the spindle.
The thread in connection with each spindle is provided with a drop finger j
which carries a weight which can be adjusted to secure the proper balancing of
the finger j. The drop finger jis pivotted to a bell crank lever k pivotted at k
and is held by the tension of the thread out of the path of an oscillating bar!
extending the length of the frame so as to do duty for all the spindles, and
actuated by a rock shaft m. The method of actuating the rock shaft m is ex-
plained later.
The bell crank lever k is connected to a vertical rod n the upper end of which
is connected to another bell crank lever o seen more clearly in Fig. 4 carrying a
belt fork o embracing the band i driving the cone cam g.
The lower end of the vertical rod is connected to a lever p secured to a rock
shaft g and carrying a fork p¹ embracing the band h driving the spindle wharve e.
The spindles are mounted in carriages B as in our said former invention and
are lowered by means of a rack and pinion s as described in the specification of
our said former Patent No. 21992 of 1896, but instead of driving the pinions s
by means of friction discs we mount them loosely upon a countershaft t provided
at each side of the frame and drive such countershafts t through a reduced train
of gearing from the driving shaft a.
The reduced speed of the countershafts is effected as follows.
We mount a worm u upon the shaft a shown in section in Fig. 2 which gears
with a worm wheel (Fig. 1). The worm wheel u is keyed upon a shaft v
carrying worms w meshing with worm wheels and thus drives the shafts y
as clearly shown in Fig. 1. In Fig. 2 one only of such worms w is shown the
worm wheel in one case being in section the more clearly to show the shaft y.
Secured upon the shafts y are spur pinions z gearing with spur wheels 1 secured
to shafts 2 which also carry spur wheels 3 which gear with spur pinions t¹ fixed on
the countershafts t. The spur wheels 3 are interchangeable to allow for variable
driving of the shafts t the brackets 4 being so shaped as to readily permit this
as will be seen from an inspection of Fig. 1. To start and to stop the loose
pinion s meshing with the rack of the spindle carriage we provide in con-
slidably mounted on
junction with each pinion s and spindle b, a clutch half
the countershaft and revolving therewith. The clutch half 5 is operated by
means of a yoke 6 secured to the rock shaft q, see Fig. 3. The arrangement of
loose pinions and clutch 5 is shown separately on an enlarged scale in Fig. 5.
The pinion s is keyed upon a sleeve 7 loosely mounted on the shaft t.
The sleeve 7 is provided with a split ring 9, the ring being expanded by a
tooth 10 on the sliding clutch half 5 when such half is moved, so that the pinion s
is driven.
The sleeve 7 and split ring 9 form the female half of the clutch. When the
pinions is idle the clutch half 5 is in the position shown in Fig. 5. The tooth 10
is in engagement with the split ring 9 which revolves with the clutch half 5
and loosely within the hollow boss of the sleeve 7. On the sliding clutch half
being moved inward towards the sleeve 7 the tooth 10 expands the ring 9 which
thus binds against the internal periphery of the boss of the sleeve 7 and drives
the same together with the pinion s fixed thereon.
Secured to the sleeve 7 is the grooved pulley 11 for the cord 12 of the counter-
balance weight of the spindle carriage.

page_text: The oscillating shaft m is operated by means of a crank 13 and connected
rod 14 the end of the connecting rod being secured to a boit 15 carried by a
disc 16. The disc is formed with an undercut groove 17 in which the head of
the bolt 15 may be slid to adjust the requisite throw of the crank 13. The disc 10
is driven by means of a spur wheel 18 mounted on the shaft 19 which also carries
the disc 16, the spur wheel 18 gearing with a pinion 20 keyed to the central
driving shaft a.
The action of the parts is as follows.
On the breakage of a thread the drop finger j falls and the opposite end rising
the finger is thus pushed forward by the swinging bar 7 carried by the rock
shaft m.
The vertical rod n is thus depressed by the bell crank lever k connected
to the rod n and drop finger j.
This downward motion of the vertical rod n actuates the belt forks o¹ 21 so as
to shift the driving bands i and h from the fast pulley f and wharve e to the
loose ones thus stopping the revolution of the cone cam g and spindle b.
At the same time the rock shaft q is operated by the vertical rod n to slightly
retract the driving clutch half 5 by means of the yoke 6 so that the split ring 9
ceases to drive the clutch half 7 to which is secured the loose pinion s gearing
with the rack r. The downward descent of the spindle carriage B is thus also
arrested.
To restart the spindle and yarn guide after "piecing" the rock shaft q is
provided with a crank 21 secured to a pendent rod 22 operated by a foot plate or
treadle 23 by depressing which the rock shaft 9 is oscillated to return the parts
to their normal positions so as to bring the driving clutch half 5 into action and
operate the vertical rod n and belt forks o¹¹ to simultaneously replace the
driving bands ih upon the fast pulley and wharve.
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) In yarn winding machinery of the indicated nature driving the spindles
and the cone cam or equivalent device for vibrating the yarn guide, and also
effecting the descent of the spindle carriage, from one common driving shaft
and providing means to effect the simultaneous stoppage of the yarn guide
spindle and spindle carriage on the breakage of a thread substantially as
described and shown.
