PROVISIONAL SPECIFICATION.
Improvements in Machinery for Winding Yarn or Thread.
I, JOHN BOYD, of Shettleston Iron Works, Shettleston, in the County of
Lanark, North Britain, Engineer, do hereby declare the nature of this invention
to be as follows, that is to say:-
My said invention has for its object to improve and modify machinery to some
extent of the kind described in my Patent Specification No. 5811 of 1886, and
especially to adapt the same for winding yarn or thread into balls or rolls, or in
other words for winding with a quick traverse into various forms and without end
disks to the spindles or bobbins upon which the yarn or thread is wound.
In one modification of my improved machinery as made for winding a single
yarn on each roll in which detector stop-motion mechanism is dispensed with,
provision is made for stopping the winding of cach roll on its attaining a pre-
determined size, the parts for this purpose being carried on one rail bracket; and
for this purpose the various parts are all shaped relatively to each other in a
manner to work in combination without interference. The bobbin or tube on which
the yarn is to be wound is upon a spindle carried by a holder centered on the
bracket, the spindle being retained in its bearings in each check of the holder by
flat springs.
The bobbin is driven by the friction surface contact on the roll of
a longitudinal driving roller; and two such rollers are provided when the machine
is made double or with winding details on both sides, a portion of the details being
arranged conveniently and compactly under the driving rollers. Each bobbin holder
has adjustably fixed to it a curved leg against which bears one arm of a bell crank the
other arm of which has applied to it one or more weights, each added weight when
there is more than one being by preference suspended to the bottom of a weight
above it. The leg is curved in a manner to maintain a suitable pressure on the roll
throughout the winding of it. The acting part of the bell crank projects laterally
from the arm, and ultimately gets under the foot of the leg, and then its action on
the leg is such as to turn the bobbin holder so that it lifts the roll clear of the
driving roller. This last mentioned action takes place on the roll reaching the
predetermined size, the leg being adjusted upon the holder to suit that size.
The yarn may be drawn from bobbins at the top of the machine or from bobbins,
hanks, or cops at the side being in the latter case by preference led up to overhead
pulleys or guides and thence down to the winding mechanism. The yarn passes
down between the driving roller and the bobbin in such a direction as to be auto-
matically caught by the traverse guide which is suitably shaped for that purpose.
The several traverse guides of a machine are fixed on one or more light longitudinal
bars suitably guided, and in the case of a double machine fixed to transverse bars
or crossheads. The traverse motion is imparted by a rotating mandril having
formed in its surface right and left helical grooves running into each other at their
ends. The helical grooves act on a swivelling cod centered in a block fitted to slide
in a
guide parallel to the mandril. These parts are enclosed in a box which
contains oil, and the block has fixed to it a rod passing out through a stuffing box
and fixed to the traverse bar, or to the end crosshead of two traverse bars. The
shaft of the mandril passes out through the outer end of the box, and is by
preference made the first-motion shaft of the machine being driven by a belt and
pulley and driving the roller shafts through spur gearing.
When my improved machinery is arranged for winding two or more strands or
yarn ends on each roll or bobbin, each set of detector stop-motion details and those
for stopping the winding on the full size being attained are carried by preference

page_text: on a single rail bracket and are disposed to some extent as shown in Figures 2
and 3 of the earlier Patent Specification hereinbefore referred to.

COMPLETE SPECIFICATION.
Improvements in Machinery for Winding Yarn or Thread.
I, JOHN BOYD, of Shettleston Iron Works, Shettleston, in the County of
Lanark, North Britain, 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, that is to say:-
My said invention has for its object to improve and modify machinery to some
extent of the kind described in my Patent Specification No. 5811 of 1886, and
especially to adapt the same for winding yarn or thread into balls or rolls, or in
other words for winding with a quick traverse into various forms and without end
disks to the spindles or bobbins upon which the yarn or thread is wound.
Winding machinery as made with my present improvements is shown on two
accompanying sheets of explanatory drawings which are hereinafter referred to in
describing the details.
Figure, 1, on Sheet, 1. of the drawings is a transverse vertical section of a
machine having different modifications on opposite sides of it. Figures, 2, to 13, on
Sheet, 2, are separate views of details and are hereinafter particularly described.
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, shown on the left-hand side of
Figure, 1, as made for winding a single yarn on each roll, and in which detector
stop-motion mechanism is dispensed with, provision is made for stopping the
winding of each roll on its attaining a predetermined size the parts for this purpose
being carried on one rail bracket, 20, adapted for being fixed on a longitudinal
rail, 21, of the framing; and for this purpose the parts are all shaped relatively
to each other in a manner to work in combination without interference. The
bracket, 20, which is seen in side elevation in Figure, 1, is shown in plan in
Figure, 2. The bobbin or tube, 22, on which the yarn is to be wound is upon a
spindle, 23, carried by a holder, 24, centered on the bracket, 20. The holder, 24,
besides being partly seen in side elevation in Figure, 1, is shown in plan in
Figure, 7, in sectional elevation in Figure, 8, and in side elevation in Figure, 9,
these figures completely showing its shape. The spindle, 23, is retained in its
bearings in each cheek of the holder, 24, by flat springs, 25. The bobbin is driven
by the frictional surface contact on the roll of a longitudinal driving roller, 26, and
two such rollers, 26, are provided when the machine is made double, or with
winding details on both sides, a portion of the details being arranged conveniently
and compactly under the said driving rollers, as shown in Figure, 1.
Each bobbin holder, 24, has adjustably fixed to it a curved leg, 27, against which
bears one arm of a bellcrank, 28, shown separately in front and side elevation in
Figures, 4, and 5, the other arm, 29, of the bellcrank, 28, having hooked on to it
one or more weights, 30, 31, each added weight, 31, when there is more than one
being by preference suspended, as shown in Figure, 1, to the bottom of the
weight, 30, above it. The leg, 27, is curved in a manner to maintain a suitable
pressure on the roll throughout the winding of it. The acting part, 29, of the bell-
crank, 28, projects laterally from the arm, and ultimately gets under the foot, 32,
of the bobbin-holder leg, 27, and then its action on that leg is such as to turn the
bobbin holder, 24, so that it moves the roll clear of the driving roller, 26. This
last mentioned action takes place on the roll reaching the predetermined size, the
leg, 27, being adjusted upon the holder, 24, to suit that size.

page_text: The yarn may be drawn from bobbins or other holders placed at the top of the
machine or from bobbins, hanks or cops placed at the side, being in the latter case,
by preference, led up to overhead pulleys, or guides, 33, and thence down to the
winding mechanism as shown in Figure, 1. The yarn passes down between the
driving roller, 26, and the bobbin, 22, in such a direction as to be automatically
caught by the traversing guide, 34; which is suitably shaped for that purpose..
One of these guides, 34, is shown enlarged in Figure, 10, which also comprises two
views, 35, 36, as projected in directions indicated by dotted lines and showing the
guide and the piece on which it is formed and which is fixed to the traverse bar, 37,
by a screw pin, 3S. Figure, 10, with the two views, 35, 36, completely show the
shape of the yarn guide, 34. The several traverse guides, 34, of a machine are
fixed on one or more light longitudinal bars, 37, suitably guided, and in the case of
a double machine, fixed to transverse bars or crossheads, 39, one of which is shown
in Figure, 10.
grooves
The traverse motion details are shown in Figures, 11, 12, and, 13, which are a
plan, a vertical section, and an end elevation. The traverse motion is imparted by
a rotating mandril, 40, having formed in its surface right and left helical
running into each other at their ends. The helical grooves act on a swivelling
cod, 41, centered in a block, 42, fitted to slide in a guide, 43, parallel to the
mandril, 40. These parts are enclosed in a box, 44, which contains oil, and the
block, 42, is formed on or las fixed to it a rod, 45, passing out through a stuffing
box, and fixed either directly to a single traverse bar (37) or as shown to the end
crosshead, 39, of two traverse bars, 37. The shaft, 40, of the mandril, 40, extends.
out through the outer end of the box, 44, and is, by preference, made the first
motion shaft of the machine, having on it fast and loose pulleys, 47, for a driving
belt, and driving the roller shafts, 26, by spur gearing. I am aware that it is not
new to employ a rotating mandril or shaft having right and left helical grooves on
it to obtain a reciprocating or "traverse" motion, but I believe it is new.to combine
the parts in the manner shown in Figures, 11, 12, and 13, and hereinbefore
described.
When my improved machinery is arranged for winding two or more strands or
yarn ends on each roll or bobbin combine detector stop-motion details with those
for stopping the winding on the full size being attained, in the manner shown on
the right hand side of Figure, 1, the detector stop-motion details being disposed to
some extent as shown in Figures, 2, and, 3, of the earlier Patent Specification
hereinbefore referred to. The combined parts for each bobbin are all carried on a
single rail bracket, 50, which is shown separately in plan in Figure, 3, and is
modified from the bracket, 20, shown in Figure, 2, so as to adapt it for the
combined details. Figure, 6, is a plan of the weighted lever, 51, which forms a
part of the detector stop-motion mechanism, being centered on the bracket, 50,
and having at its outer end a catch to engage with the swinging plate, 52, holding
the detector wires, 53, whilst its inner end is shaped to lift the bobbin or roll, 22,
out of contact from the driving roller, 26, whenever a wire, 53, dropping in con-
sequence of the breaking or failure of a thread gets into the way of the wiper
shaft, 54, which then moves the swinging plate, 52, so as to release the lever, 51.
These detector step-motion details only differ from those shown and described
in the earlier Patent Specification hereinbefore referred to, in being modified in
shape where necessary to enable them to be combined with the other details and to
work without interference.
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 bobbin holder (24) with its adjustable curved
leg (27) combined with the weighted bellcrank (28) and operating substantially as

page_text: 2. The combination of the parts referred to in the first claim with the single rail
bracket (20) which carries them substantially as hereinbefore described.
3. The combination of the parts referred to in the first claim with the detector
stop-motion details and with the single special rail bracket (50) which carries them
substantially as herein before described.
4. The improved arrangement and combination of parts constituting the traverse-
motion mechanism substantially as shown in Figures, 11, 12, and 13, of the
accompanying drawings and hereinbefore described.
