Improvements in Winding or Spooling Machines.
THOMAS THORPE Hosiery Machinist, 10 Beech Avenue New Basford,
Nottingham do hereby declare the nature of this invention to be as follows:-
With
My improvements consist of an adaptation of friction wheels, with suitable
levers and shaft, whereby I obtain a differential speed of spool or bobbiu.
this arrangement, when the yarn is being wound on the thick part of spool or
bobbin it revolves more slowly, and as the yarn nears the thin part of spool or
bobbin it revolves more quickly, consequently, the take up of yarn is much more
regular, the strain or tension on the yarn is much less, and the operator is
enabled to wind more yarn, with much less waste, than is possible on the ordinary
machinery.
In carrying out my invention the spindles are preferably driven by a longitudinal
driving shaft carried on the underside of the spindles in bearings secured to the
framing secured to this shaft are friction pulleys the peripheries of which are in
frictional contact with the underside of friction discs secured to the lower end of
the spindles.
By moving the driving shaft longitudinally the friction pulleys may be moved
towards or away from the axis of the friction discs and the speed at which the
spindles revolve he thus increased or decreased.
The driving shaft is reciprocated longitudinally preferably by a bell crank lever
pivotted to the framing one end of which engages in an annular recess in a sleeve
or collar secured to the shaft, or other convenient arrangement, and the other end
is connected by a link to an arm or lever connected to the rocking shaft which
operates the thread guides. A corresponding movement to that of the thread
guides is thus transmitted to the friction pulleys and the position of the latter
with reference to the axis of the friction discs is governed by that of the thread
guides.
With this arrangement the yarn is drawn off at a more constant speed and the
spooling is effected more expeditiously and with less breakage than is the case with
spindles which revolve at the same speed throughout.

Improvements in Winding or Spooling Machines.
I, THOMAS THORPE of Beech Avenue, New Basford, in the Borough of
Nottingham, Hosiery Machine Builder 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 improvements in winding or spooling machines and it
has for its object to impart rotary motion of varying speed to the spindles, so that
when winding on taper spools or bobbins or on a taper surface formed by the
preceding layers of yarn as in the case of spooling, the threads may be drawn off' at
a more uniform speed and be consequently less liable to breakage.
For this purpose I employ friction discs for transmitting motion from the driving
shaft to the spindles the relative position of which discs may be changed by the
lateral movement of the driving shaft, so that when the yarn is being wound on
[Price 8d.1

page_text: the thick part of the bobbin or spool the spindles revolve at a lower speed than
when the yarn is being wound on the thinner part of the bobbin or spool, the speed
being gradually increased and decreased as the thread guides traverse from one
part of the spool or bobbin to another.
By this arrangement the yarn is taken up at a more regular rate the strain or
tension on the yarn is much less and the operator is enabled to wind more yarn with
much less waste than is possible with existing arrangements.
The invention will be best understood by reference to the accompanying drawings
in which
Figure 1 is a front elevation and
Figure 2 a.side elevation showing my invention.
Secured to the lower ends of the spindles a are friction discs the lower surface
of each of which is in frictional contact with the periphery of a friction disc c
secured to the longitudinal.shaft d.
The shaft. which is carried in bearings and driven in the usual manner is
reciprocated longitudinally.so that the discs c alternately move towards and away
from the centre of the discs and thus increase and decrease the speed of rotation
of the spindles, this movement is preferably arranged so that the speed of the
spindles a is increased. as the thread guides or bar funder which the threads g are
carried rises, and decreased as the bar f descends.
The shaft is reciprocated longitudinally by means of a bell crank dever h
pivotted at to the framing, the lower end of which is provided with a fork i
which engages in an annular recess in a collar d' secured to the shaft d. The end h².
of the lever is connected by a link to the worm lever k, operating through the
shaft the thread guides or bar f; the worm lever k may be of the usual
construction and operated in a well-known manner.
It is obvious that the discs c may be moved laterally on the shaft d but 1
preferably employ the arrangement described as it is the most convenient.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
1. A.winding or spooling machine in which a rotary motion of varying speed is
communicated to the spindles a by means of friction discs b secured to the spindles a
and discs c carried by the driving shaft d and capable of being reciprocated laterally
substantially as described and illustrated in the accompanying drawings.
2. In a winding or spooling machine such as described the combination with a
spindle a and friction disc b of a disc c carried by and reciprocating with or
independently of the driving shaft substantially as and for the purpose described
and illustrated in the accompanying drawings.
3. In a winding or spooling machine such as described the combination with
shaft and worm lever of a lever such as 2 for communicating the movement
of the lever to the shaft & substantially as described and illustrated in the
..accompanying drawings.
