Improvements in Machines for Winding or Beaming Yarns.
I, DAVID MCTAGGART of 91 Exchange Street Worcester, in the County of
Worcester and State of Massachusetts, United States of America, Manufacturer,
do hereby declare the nature of my invention for improvements in winding
machines, to be as follows:-
My improvements relate to that class of winding machines in which several
strands are taken from separate spools, bobbins, or cops, and are simultaneously
wound side by side upon a single spool or beam. The individual strands held upon
separate spools, or bobbins, pass through a series of eyes, or guides, to bring the
strands parallel with each other and into the same plane and conduct them to a
rotating spool, or beam, upon which they are wound.
1. The first part of my invention relates to the means for relieving that portion
of each individual strand next the winding spool from any undue tension which
may accidentally arise by the strand becoming caught and prevented from
unwinding freely from the bobbin, so that an increase in the tension of a strand,
in excess of its tensile strength will cause it to break nearer to the bobbin than to
the winding roll; thereby allowing the machine to be stopped.and the strand
pieced before the broken end has passed upon the winding spool, or, beam; and it.
consists in placing a freely rotating roll between the bobbins and the winding
spool with its axis parallel with the axis of the latter and carrying each of the
strands once around the roll so the movement of the strands in winding will cause.
the roll to rotate. In case a strand becomes caught in unwinding from the bobbin
the strain upon the strand will be received by the intermediate roll, owing to the
bight of the strand on the roll and the increase in tension upon the strand will be
distributed between the bobbin and the intermediate roll, so that when a breakage
occurs, the strand will break between the intermediate roll and bobbin instead of
between the intermediate roll and winding spool, or beam.
II. The second part of my invention relates to a take-up mechanism by which
the slack of the strands is taken up in case it is necessary to partially reverse the
motion of the winding spool in order to find a broken end or for other purposes;
and it consists in conducting the strands as they approach the winding spool between
a pair of parallel rods carried at their ends by disks capable of rotating about &
common axis located midway between the parallel rods.
A cord is wound upon the periphery of one of the disks and carried over
a pulley to change the direction of its motion and a weight is suspended
by the cord, which is applied to rotate the disks and hold the parallel rods
against the opposite sides of the strands. The tension upon the strands during
the operation of winding will counteract the weight; but when the winding spool
is reversed the weight is free to descend and rotate the disk and parallel rods,
thereby increasing the deflection of the strands from a straight line and taking up
the slack.
III. The third part of my invention relates to the mechanism for compressing
the strands as they are being wound; and it consists in a rocking frame comprising
a pair of claws.which inclose a little more than half of the periphery of a metallic
pressure roll with its axis parallel with the axis of the rocking frame and of suitable
length to go between the heads of the winding spool and rest upou the strands

page_text: after they are wound, thereby compressing them between-the pressure roll and the
barrel of the winding spcol. The rocking frame further comprises a bar placed
transversely to, and extending upon opposite sides of the axis of the rocking frame.
The transverse bar forms a track for a sliding block, which is moved thereon by
means of a rotating screw. One end of a cord or chain is attached to said sliding
block and carried over a pulley suspended above the frame and a weight is attached
to the opposite end of the cord, or chain, so as to exert a pulling strain upon the
rocking frame. When the sliding block is moved along the transverse bar upon
the side of the axis of the rocking frame opposite to the pressure roll, the weight
tends to rock the frame to carry the pressure roll down upon the strands which are
wound upon the spool, or beam, but when the sliding block is moved to the same side
of the axis of the frame as the pressure roll, the weight then tends to rock the frame
in the opposite direction and lift the pressure roll. By moving the sliding block
from one side to the other of the axis of the rocking frame the weight suspended
by the cord or chain is made to either increase the pressure of the pressure roll
upon the winding spool or lift it therefrom.
IV. The fourth part of my invention relates to a traversing mechanism by which
the strands are traversed upon the winding spool at their point of delivery thereto;
and it consists in forming a series of shallow V-shaped grooves in the periphery of
the pressure roll; each of said grooves extending entirely around the roll and lying
in a plane which is oblique.to the axis of the roll; the obliquity, or pitch, of each
groove being equal to the distance between the strands. Each of the strands is
conducted into one of the grooves of the pressure roll and is rolled between the
pressure roll and winding spool as the winding spool is rotated; each strand running
in one of the grooves a short distance before it is wound upon the winding spool,
so the rotation of the pressure roll, during the operation of winding, will cause a
traversing motion to be imparted to each of the strands a distance equal to the
pitch of the V-shaped grooves.
V. The fifth part of my invention relates to the disposition of the V-shaped
grooves upon the pressure roll; and it consists in so arranging each groove that
the strand held therein will be traversed in one direction along the winding spool
during slightly less than half a revolution of the pressure roll and be traversed in
the opposite direction during a little more than half a revolution of the pressure
roll, so that when the circumference of the pressure roll and winding spool are
equal, the strand will not be laid in the same place at each succeeding revolution
of the winding spool.
VI. The sixth part of my invention relates to the mechanism for driving the
winding spool, and it consists in employing three pulleys held concentrically upon
the shaft of the winding spool; one of said pulleys being a loose pulley to carry the
belt when the winding spool is at rest; the second pulley is attached to one end of
a sleeve journaled upon the shaft of the winding spool and passing through the hub
of the loose pulley. Upon the opposite end of the sleeve is attached a gear
engaging a gear upon an intermediate shaft journaled in bearings parallel with the
shaft of the winding spool and carrying a second gear which engages a gear
attached to the. shaft of the winding spool. The relative sizes of these gears is
such, that when the driving belt is shifted from the loose pulley to the pulley
attached to said sleeve, the winding spool will be driven at a reduced rate of speed;
the third pulley is attached directly to the. end of the shaft of the winding spool;
all three pulleys being arranged side by side so the driving belt may be shifted from
the loose pulley across the second pulley upon the face of the third pulley. As the
belt passes over the second pulley the winding spool is started at a reduced rate
of speed, thereby overcoming its inertia and imparting a rotary movement to the
third pulley before the belt is shifted upon it. When the winding spool is being
driven with the driving belt upon the third pulley, which is attached directly to
the shaft of the winding spool, the second pulley which is attached to the sleeve,
is driven through the back-gearing, and runs at a higher rate of speed than the
specd of the winding spool and as the belt is shifted back to the loose pulley.it

page_text: will serve as a brake during its passage across the second, or interme liate pulley,
to check the momentum of the winding spool.
VII. The seventh part of my invention relates to the shipping mechanism by
which the driving power is connected with, or disconnected, from the machine, and
it consists in connecting a sliding shipper-bar with a rocking spindle journaled
upon the floor in front of the machine and carrying a triangular foot-plate attached
thereto and extending transversely above the spindle. The apex of the foot-plate
forms a rest for the heel of the operator and by shifting the toe of the foot from
right to left, over the base of the foot-plate a pressure is applied upon one side or
the other to rotate the spindle and slide the shipper-bar in one direction in order
to start the machine, or in the opposite direction to stop

Improvements in Machines for Winding or Beaming Yarns.
I, DAVID MCTAGGART, of 91 Exchange Street, Worcester, in the County of
Worcester and State of Massachusetts, United States of America, Manufacturer,
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 improvements relate to that class of winding machines in which several
strands are taken from separate spools, bobbins, or cops, and simultaneously wound
side by side upon a single spool, or beam.
In the following description of my invention and the manner in which the same
is to be performed reference is made to the reference letters and figures in the
accompanying drawings which represent a winding machine embodying my inven-
tion showing the manner of putting my invention into practice and forming a part
of this specification.
Figure 1 shows a front elevation of my improved winding machine.
Figure 2 is an end view.
Figure 3 is a vertical sectional view on line 3, 3 Figure 1, showing the operative
mechanism concerned in winding and compressing the strands of yarn upon the
spool.
Figure 4 represents a top view of one end of the winding drum with connected
belt pulleys and intermediate gearing by which the winding drum is rotated, portions
of said figure being shown in sectional view in order to disclose more clearly the
construction and operation of the several parts.
Figures 5 and 6 represent sections of the pressure roll provided with V-shaped
grooves into which the strands are conducted as they are being wound upon the
winding spool; said V-shaped grooves being arranged obliquely to the axis of
the roll so that the strands contained therein will be traversed along the winding
spool.
Figure 7 is a diagrammatic figure illustrating the disposition of one of the
V-shaped grooves upon the pressure roll.
Like parts are indicated in the accompanying drawings by like letters and
figures of reference.
. Referring to the drawings A, A denotes the framework by which the operative
parts of the machine are supported; 1 is a horizontal shaft journalled in the frame-
work and carrying a drum 2 upon which the winding spool 3 rests and is driven by

page_text: its contact with the rotating drum 2. The winding spool is held in place by
inserting its gudgeons 4 in blocks 5 which are capable of sliding upon vertical
rids 6 supported by the framework A. The drum 2 is driven by a belt through
the mechanism shown in detail in Figure 4 and it consists of a belt pulley 7
attached to the end of the shaft 1; a belt pulley 8 attached to one end of a
sleeve 9 which turns loosely upon the shaft 1 and has a piniou 10 attached to
the opposite end of the sleeve and engaging a gear 11 attached to an intermediate
shaft 12 which is journalled in the frame of the machine and carries a pinion 13 which
engages a gear 14 attached to the shaft 1; the gears being so proportioned that
when the drum 2 is driven through the belt pulley 8 aud intermediate gearing it
will be driven at a less rate of speed than when driven directly through the belt
pulley 7, and when the drum 2 is driven through the belt pulley 7 the pulley 8
will be rotated at a higher rate of speed than the pulley 7, being driven by the
shaft 1 through the intermediate gearing. A loose pulley 15 rotates upon the
sleeve 9 to carry the driving belt when the machine is not in operation.
When the machine is started the driving belt is shifted from the loose pulley 15
across the pulley 8 to the pulley 7 causing the drum 2 to be slowly rotated as the
belt passes across the face of pulley 8 and overcoming the inertia of the drum 2
before the belt reaches pulley 7. When the machine is stopped the belt is shifted
from pulley 7 across pulley 8 to the loose pulley 15 and as the pulley 8 is being
rotated at a higher rate of speed than pulley 7 the belt is caused to act as a brake
to gradually overcome the momentum of the drum.
The winding spool 3 is placed upon the rotating drum 2 with its heads over-
lapping the ends of the drum which is of sufficient length to substantially fill the
space between the heads of the winding spool. Upon the winding spool and resting
thereon is an iron pressure roll 16 of sufficient length to fill the space between its
heads. The pressure roll 16 is held by the claws.17, 17, which inclose slightly
more than one-half the periphery of the roll so that the elevation of the claws 17
will lift the pressure roll off the winding spool 3. The claws 17 are pivotally
connected with arms 18, 18 attached to a rocking shaft 19 supported by brackets 20
attached to the framework. Each of the claws 17 is pivotally connected by a link 21
with the brackets 20 in order to hold the claws in a horizontal position as the shaft 19
is rocked. Suspended transversely beneath the rocking shaft 19 is a bar 22 having
a screw 23 journalled thereon and forming a track for a sliding block 24 which is
provided with a nut engaging the screw 23 so the rotation of the screw will cause
the block 24 to be moved along the transverse bar 22 from one side to the other of
the rocking shaft 19. A weight 25 is applied, by means of cords 26, to exert a
downward pulling strain upon the sliding block 24.
When the sliding block 24 is moved to the inner end of the transverse bar 22
the weight 25 will tend to rock the shaft 19 and carry the pressure roll 16 down
upon the strands of yarn as they are wound upon the winding spool 3 thereby
compressing them between the pressure roll and the barrel of the windling spool.
When the sliding block 24 is moved to the outer end of the transverse bar 22 the
weight 25 will then be exerted to rock the shaft 19 in the opposite direction and
raise the pressure roll 16 off the winding spool..
The strands B are taken from individual bobbins, or cops, not shown, and are
conducted through an overhead guide plate 27 and carried once around a roll 28
journalled in the framework of the machine; from the roll 28 the strands are
conducted between a pair of parallel rods 29, 30 which are held at their ends by
disks 31 and 32 which are capable of rotating about a common axis lying in a
plane midway between the rods. A cord 33 is attached to the disk 31 and carried
over a roll 34 to change its direction with a weight 35 suspended, from its opposite
end so as to rotate the disks and hold the parallel rods against the opposite sides
of the strands B. While the strands B are being wound upon the spool 3 their
tension, exerted against the rods 29 and 31, is sufficient to counterbalance the
weight 35; but in case the tension upon the strands is removed the weight 35 will

page_text: then rotate the rods 29 and 30 and take up the slack in the strands. The
strands B are conducted over a guide plate 36 provided with a series of eyes or
notches to hold the strands equidistant, as they are conducted to the winding
spool 3.
In order to traverse the strands B along the winding spool I provide the pressure
roll 16 with a series of shallow V-shaped grooves 37, each of said grooves passing
entirely around the roll and at an oblique angle to its axis; the pitch of each groove
being equal to the distance between the strands and the number of grooves being
equal to the number of strands.
The strands B as they are delivered from the lower guide plate 36 to the winding
spool 3 are held at a proper angle to bring them in contact with the surface of the
pressure roll 16 so that each strand will lie in its corresponding V-shaped groove
and as the pressure roll 16 is rotated a traversing motion back and forth will be
given to each of the strands equal to the pitch of the V-shaped grooves. The
V-shaped grooves are disposed on the pressure roll so that as the roll is rotated
the strands will be carried toward one end of the winding spool a distance equal to
the space between the strands during a little less than one-half a revolution of the
pressure roll; each strand is then wound for a short distance in a straight line or
at right angles with the axis of the spool. The strands are then moved back a
distance equal to the space between the strands during a little more than one-half
a revolution of the pressure roll and they are then wound for a short distance in a
straight line or at right angles with the axis of the winding spool. The traversing
motion of the strands in one direction is accomplished during less than one-half a
revolution of the pressure roll and the traversing motion in the opposite direction
is accomplished in a little more than one-half a revolution of the pressure roll in
order to prevent the strands from being laid on the winding spool in the same
path during two successive rotations of the pressure roll.
The short distance in which the strands are wound in a straight line, or at right
angles with the axis of the winding spool causes each strand to be held from
slipping on the spool as the direction of the traversing motion is changed from
right to left or left to right. The section of the pressure roll shown in Figure 5
represents the V-shaped grooves lying obliquely to the axis of the roli and
the section of the pressure roll shown in Figure 6 represents the arrangement of the
V-shaped grooves where the direction of the traversing motion is changed. The
diagrammatic Figure 7 represents a portion of the periphery of the pressure roll
extended in a plane surface; the two oblique lines 38 and 39 represent the relative
lengths of the oblique sections of the V-shaped groove in the pressure roll; the
oblique line 38 being considerably shorter than the oblique line 39 which causes
the strand to be traversed in one direction during less than half the revolution of
the pressure roll and in the opposite direction during slightly more than half a
revolution of the pressure roll.
The driving belt is carried through an eye 40 which is attached to a shipper
bar 41 operated by a vibrating lever 42, rod 43 and an arm 44 carried by the
rocking shaft 45.
The shaft 45 has attached thereto laterally projecting wings 46, 46 by which th
shaft 45 is rocked by the pressure of the foot in order to shift the belt upon the
driving pulley.
The first part of my improvement consists in carrying the strands from individual
bobbins or cops once around the friction roll 28 so that the roll will be rotated by
the bight of the strands for the purpose of equalizing the tension and cause any
increase in the tension of an individual strand to be distributed between the bobbin
and the friction roll 28. This device I have ascertained has been previously used
and I therefore do not herein claim the same to be new.
The second part of my improvement relates to the device for taking up the slack
of the strands by the rotating pair of parallel rods held against opposite sides of
the strands by a counterbalance weight 35 and flexible connection 33.

page_text: The third part of my improvement relates to the compressing mechanism by
which a pressure roll is applied to compress the yarn upon the winding
spcol by means of a weight 25 with means for shifting the application of
the weight from one side to the other of a vertical plane containing the axis of
the rocking shaft 19 by which the pressure roll is supported so that the weight
can be applied at will to either crowd the pressure roll against the yarn, or lift it
entirely out of contact with the yarn.
The fourth part of my improvement relates to a yarn traversing mechanism which
comprises a series of V-shaped grooves which are located in the periphery of a
roll which is rotated by its contact with the yarn as it is being wound upon the
winding spool so that the speed of the grooved roll will at all times correspond
with the speed of the surface of the yarn wound upon the spool.
The fifth part of my improvement relates to the disposition of the V-shaped
grooves upon the periphery of the pressure roll whereby the strands are laid in
different paths during successive revolutions of the winding spool.
The sixth part of my improvement relates to the driving mechanism by which the
-drum which supports the winding spool is rotated. An arrangement of two driving
pulleys and back gearing has hitherto been used, whereby the drum is rotated at
a fast or slow speed by shifting the belt from one driving pulley to the other; but
I have arranged the mechanism so that both driving pulleys are simultaneously
rotated whenever the drum revolves thereby utilizing the driving mechanism for
the purpose of overcoming the inertia of the drum when the machine is started and
-overcoming its momentum when the machine is stopped.
The seventh part of my improvement relates to the sifting mechanism by which
the driving belt is shifted by foot pressure. I have, however, ascertained that this
belt shifting mechanism has previously been used and is therefore not new.
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:
First. The combination of a pair of disks journalled in the framework with
-coincident axes, a pair of parallel rods held by said disks, and upon opposite sides
of the strands to be wound and means for rotating said disks and carrying said rods
against the strands, as and for the purpose set forth.
Second. The combination of a pressure roll and a rocking shaft by which said
roll is supported, a bar arranged transversely to the axis of said rocking shaft, a
bluck capable of sliding in said transverse shaft, a weight applied to exert a pulling
strain upon said sliding block and means for moving said block on opposite sides
of the axis of said rocking shaft, as and for the purpose set forth.
Third. The combination with mechanism for rotating the winding spool of a
pressure roll arranged to bear upon the strands as they are wound upon the
winding spool and be rotated by its contact with the strands, said pressure roll
having a series of V-shaped grooves arranged obliquely to the axis of the roll
-corresponding with the number of the strands, whereby said strands are traversed
along the winding spool, as and for the purpose set forth.
Fourth. The traversing roll provided with a series of V-shaped grooves arranged
obliquely to the axis of the roll and corresponding in number to the number of
strands and having a pitch equal to the distance between the strands with the
obliquity of said grooves so arranged as to traverse the strands in one direction
-during less than a half revolution of the roll and in the opposite direction
during more than a half revolution of the roll, as and for the purpose set
forth.
Fifth. The combination of a shaft, a rotating drum carried by said shaft by
which the winding spool is rotated, a pulley attached to said shaft, a sleeve turning
loosely on said shaft and carrying a pulley and a pinion, an intermediate shaft
carrying gear wheels engaged by the pinion on said sleeve and engaging a gear
-on the shaft of the drum whereby both pulleys are rotated at different speeds

page_text: whenever either of said pulleys are driven by the belt and the shifting of the belt
in starting or stopping the drum, made to overcome both inertia and momentum of
the drum, as and for the purpose set forth.
Dated this Thirteenth day of April 1897.
