Improvements in Machinery for Winding Yarn or Thread.
I, JOHN BOYD, of Shettleston Iron Works, in the County of Lanark, Engineer,.
do hereby declare the nature of this invention to be as follows:-
My said invention has for its object to improve or modify machinery to some extent
of the kind described in my Specification No. 9380 of 1891, for winding yarn or
thread into balls or rolls, which improvements can also be advantageously adapted
for various other kinds of winding machinery.
In one modification of my improved machinery as made for winding single yarn
on each roll, a combination of parts for the purpose of holding the roll in proper
position as it is being wound,-for stopping and starting the winding,-for regulating
the pressure of the roll, as it is being wound on to the surface of the driving
roller, for stopping the winding of each roll on its attaining (within certain limits)
any predetermined size, for setting the holder and its spindle at any angle to the
driving roller, and for more conveniently removing the wound ball from its
holder after it is wound, are all carried by a single rail bracket, fixed to a
longitudinal rail, placed above and behind the driving rollers, the roll of yarn
being driven and wound by being pressed down on the top of the driving roller.
The tube on which the yarn is to be wound has a holder, on one forwardly
projecting arm of which is pivoted a swivel crank piece, the latter having fixed to
it one end of a lateral projecting dead spindle, which carries the tube and on which
it revolves; the other outer end of the. spindle, when in its working position,.
engaging in a notch, on the other arm of the holder. The pivoted dead spindle
when a roll of yarn is being removed from the holder, is swung outwards, the arm.
of the holder having a stop with which the crank piece comes in contact to prevent.
the spindle being moved too far outwards. Instead of a dead spindle the swivel
crank piece may carry a live spindle, which may revolve with the tube or yarn
which is being wound on it, the length of the crank and the outward swing of its.
dead or live spindle being arranged so as to have the holder as narrow as possible
and to save space between contiguous holders, when pivoted spindles are used.
The holder has two back snugs and a spindle, carried by two outwardly projecting
front snugs of the rail bracket, by which the holder is hinged to the bracket.
On the same spindle is pivoted a combined upwardly projecting hand starting and
stopping lever and downwardly projecting curved leg piece, and above and below
the centre of the latter are two angled adjusting set screws, which engage with.
a properly shaped part of the back cross bar of the holder, and between the points
of these screws, the position of the holder is adjusted and fixed, so that the winding
of the roll of yarn may be stopped at any predetermined diameter. The rail
bracket has also a projection which engages with the holder, to prevent its front
arms and spindle coming too close to the driving roller.
The rail bracket has also two downwardly and inwardly projecting arms, carrying
a crosspin, on which is fulcrumed a bell crank lever, having an inwardly projecting.
arm, on which is suspended or fixed an adjustable weight, so as to give the necessary
pressure to the projecting acting part on the other arm of the bell crank lever,
which bears on the downwardly projecting curved leg lever, the latter being curved
so as to maintain a suitable pressure on the roll, throughout the winding of it, the

page_text: acting part of the bell crank lever ultimately getting under the foot of the curved
leg and then its action is such as to lift the holder, so that it moves and holds the
roll, when it has reached its predetermined diameter, clear of the driving roller,
and also when it has been moved into this position by the stopping and starting
hand lever. The rail bracket has also two top snugs, which in ordinary cases rest
on the top of the longitudinal rail, but when the bracket is made adjustable, so as
to set the holder and its spindle at any angle to the driving roller, one or both of
the snugs are screwed and are fitted with set screws, which bear on the top rail, so
as for this purpose to set the bracket at any required angle.
Yarn, by the present improved arrangement, is more conveniently wound from
hanks or bobbins or cops placed below or in front of the winding parts, the yarn
passing upwards and inwards between the driving roller and the tube or roll on
which it is being wound, so as to be automatically caught by a suitably shaped
thread guide fixed to a light longitudinal, reciprocating traverse bar, placed in
front of the winding parts and suitably guided. and as close as possible to the
point of contact of the driving roller and the tube or roll but without touching
same.
Instead of the yarn being caught and guided by a reciprocating traverse bar and
guide, it may in some cases be traversed, as is sometimes done, by an oblique slot
formed between two contiguous revolving drums, by which at the same time the
roll by surface contact is wound, for which arrangement of winding mechanism
the present improved combination of rail bracket and the combination of parts
carried on same, for winding balls of any predetermined. size, is well adapted.
By another modification of my improved mechanism the traverse motion is
imparted as in my former patent referred to, by a rotating mandrel having
formed on its surface right and left helical grooves running into each other at
their ends.
1, JOHN BOYD, of Shettleston Iron Works, in the County of Lanark, Engineer,
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:-
My said invention has for its object to improve or modify machinery to some
extent of the kind described in my Specification 'No. 9380 of 1891, for winding yarn
or thread into balls or rolls, which improvements can also be advantageously
adapted for various other kinds of winding machinery.
Winding machinery as made with my present improvements is shewn in two
accompanying sheets of explanatory drawings which are hereinafter referred to in
describing the details.
..Fig. 1 in sheet, one of the drawings is a transverse vertical section and Fig. 2 is a
front view of one modification of my improved winding machinery but in order to
make some of the important parts of the mechanism more distinct some parts which
are shown in Fig. 1 are not shown in Fig. 2.
Figs. 11 and 12 on sheet 2 are a transverse vertical section and a plan view of
another modification of my improved winding machinery.
. Figs. 3 to 10 in sheet 1 are separate views of details and are hereinafter
particularly described..

page_text: In these drawings the same reference numerals are used to mark the same or like
parts wherever they are repeated.
In one modification of my improved machinery, Figs. 1 and 2 on sheet 1, as made
for winding single yarn on each roll, a combination of parts, for the purpose of
holding the roll in proper position as it is being wound, for stopping and starting
the winding, for regulating the pressure of the roll (as it is being wound) on to the-
surface of the driving roller, for stopping the winding of each roll, on its attaining
(within certain limits) any predetermined size, for setting the holder and its spindle
at any angle to the driving roller, and for more conveniently removing the wound
ball from its holder after it is wound, are all carried by a single rail bracket 13,
Figs. 1, 2, 4 and 5, on sheet 1, fixed to a longitudinal rail 14, placed above and:
behind the driving roller 15, the roll of yarn 16 being driven and wound by being
pressed down on the top of the driving roller 15.
The tube 17 on which the yarn is to be wound has a holder 18, on one forwardly
projecting arm of which is pivoted a swivel crank piece 19, the latter having fixed:
to it one end of a lateral projecting dead spindle 20, which carries the tube 17 and.:
on which it revolves, the other outer end of the spindle, when in its working..
position, engaging in a notch 21, on the other arm of the holder. The pivoted):
dead spindle 20 when the roll of yarn 16 is being removed from the holder, is
swung outwards as shown in Fig. 3, the arm of the holder having a stop 22 with
which the crank piece.19, comes in contact to prevent the spindle being moved too
far outwards. Instead of a dead spindle the swivel crank piece 19 may carry.a live
spindle 23, Fig. 10 shown on larger scale, which may revolve with the tube 17 or
yarn lö which is being wound.on it, the other end of the live spindle engaging in.:
the notch.21 on the other arm of the holder. The outer. end of the live spindle
may be provided with a bush 23' and may have a spring 231 at its centre to prevent.,
the tube 17 on which the yarn is wound slipping on the live spindle, the length of
the crank 19 and the outward swing of its dead spindle 20 or live spindle 23 being
arranged so as to have the holder 18 as narrow as possible and to save space
between contiguous holders, when pivoted spindles are used. The holder has two,
back snugs 24, 25, and, a spindle 26, carried by two outwardly projecting front:
Enugs 27, 28, of the rail bracket 13 by which the holder is hinged to the bracket..
On the same spindle is pivoted a combined upwardly projecting hand starting aud
stopping lever and downwardly projecting curved leg piece 29, and above and below:
the centre of the latter are two angled adjusting set screws 30 and 31 which engage
with a properly shaped part 32 of the back cross bar of the holder 18 and between-
the points of these screws, the position of the holder is adjusted and fixed, so that
the winding of the roll of yarn may be stopped at any predetermined diameter.
The rail bracket 13 has also a projection 33 which engages with the holder 18, to,
prevent its front arms and spindle coming too close to the driving roller 15.
“་
.
The rail bracket 13 has also two downwardly and inwardly.projecting arms, 34, 35,
carrying a cross pin 36 on which is fulcrumed a lever 37, having an inwardly,
projecting arm 38, on which is suspended or fixed an adjustable weight 39, so as to
give the necessary pressure to the projecting acting part 40, on the other arm 37, ofr
the lever 38, which bears on the downwardly projecting curved leg lever 29, the latter..
being curved so as to maintain a suitable pressure on the roll 16 throughout the
winding of it, the acting part of the bell crank lever ultimately getting under the
foot 41 of the curved leg and then its action is such as to lift the holder 18,
so that it moves and holds the roll 16 when it has reached its predetermined
diameter, clear of the driving roller 15 and also when it has been moved into this
position by, the stopping and starting hand lever 29. The rail bracket 13 has also.
two top snugs 42, 43, which in ordinary cases rest on the top of the longitudinal
rail 14, but when the bracket is made adjustable, so as to set the holder and its.
spindle 20 at any angle to the driving roller 15, one or both of the snugs 42, 43, are
5 screwed and are fitted with set screws 44, 45, which bear on the top rail, so as for
this purpose to set the bracket at any required angle, when winding conical rolls.
of yarn.

page_text: Yarn by the present improved arrangement, is more conveniently wound from
hanks or bobbins or cops placed below or in front of the winding parts, the yarn 46
passing upwards and inwards between the driving roller 15 and the tube 17 or roll 16
on which it is being wound, so as to be automatically caught by a suitably shaped
thread guide 47, fixed to a light longitudinal reciprocating traverse bar 48, placed
in front of the winding parts and suitably guided and as close as possible to the
point of contact of the driving roller 15 and the tube 17 or roll 16, but without
touching same.
The driving roller 15 is driven in any convenient way and as in the former
patent referred to (No. 9380 of 1891) gives motion to a rotating mandrel having
right and left helical grooves formed on its surface and running into each other at
their ends which in its turn communicates the necessary quick reciprocating motion
to the traverse bar 48.
Instead of the yarn 46 being caught and guided by a reciprocating traverse bar
and guide, it may in some cases be traversed as is sometimes done, by an oblique
slot 49, Figs. 11 and 12, formed between two contiguous revolving drums 50, by
which at the same time the roll 16 by surface contact is wound, for which
arrangement of winding mechanism, the present improved combination of rail
bracket and the combination of parts carried on same, for winding balls of any
predetermined size is well adapted, the various parts of the mechanism being made
so as to work clear of the revolving drums 50. In some cases, as shown in Figs. 11
and 12, instead of the holder 18 being made with a crank 19 and spindle 20 or 23 a
holder 51 may be used as in my former patent referred to with a live spindle 52
retained in its bearings in each arm by flat springs 53.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved construction of tube or roll holder 18 with its pivoted swivel
crank piece 19 and the lateral projecting dead spindle 20 or live spindle 23 operating
substantially as and for the purposes herein before described.
2. The combined upwardly projecting hand starting and stopping lever and
downwardly projecting curved leg piece 29 with its adjusting set screws 30 and 36,
substantially as and for the purposes hereinbefore described.
3. The combination of the hand starting and curved leg lever 29 and the weighted
bell crank lever 37, 38, substantially as and for the purposes hereinbefore described.
4. The combination of the tube or roll bolder 18 or 51 with the starting and
curved leg lever 29 and the lever 37, 38, as and for the purposes herein before
described.
5. The combination of the parts referred to in the fourth claim with the single
adjustable rail bracket 13 which carries them substantially as herein before
described.
6. The combination of the parts referred to in fourth and fifth claims with
revolving drums 50 having formed between them an oblique slot 49 for the purpose.
of winding and traversing the thread as shown in Figs. 11 and 12 as and for the
purposes herein before described.
