PROVISIONAL SPECIFICATION.
Improvements in Machines for Winding Yarns or Threads.
I, SAMUEL HEY of 56 Low Street, Keighley in the County of York, Patent
Agent, do hereby declare the nature of this invention, as communicated to me from
abroad by William Anthony Smith of Lawrence, Essex County, Massachusetts,
United States of America, Gentleman to be as follows:-
This invention relates to machines for forming accumulations of thread upon
spools or cop tubes, either straight or conical, by the operation of cross-winding;
that is to say, feeding the yarn to a continuously rotating spool or tube by means
of a reciprocating or traversing yarn guide. In organised machines of this
character, a large number of spools or tubes are wound simultaneously, requiring
the use of a large number of yarn-guides and mechanism for reciprocating the same.
In many spooling machines now in use, all the yarn-guides in the machine are
grouped together as one gang, all moving simultaneously and all arrested simul-
taneously at the end of the movement in each direction, so that the reversal of the
movement is attended with considerable jar, involving wear and strain of the
machine, as well as a very objectionable noise and rattle. In other machines now
in use, each guide is moveable independently of all the others, but these machines
are necessarily complicated and expensive, besides being very noisy when in
operation.
My invention has for its object to provide a machine of this character, in which
the objectionable features above-mentioned shall be eliminated, so that the machine
will run without objectionable shocks or jars, and with the minimum noise. The
invention also has for its object to enable the accumulation of yarn on a conical
cross-wound spool or tube to be more evenly and uniformnly wound from end to end
than heretofore.
To these ends, the invention consists in the improvements which I will now
proceed to describe.
The machine has a series of driving-rolls which rotate the spools or dummy
bobbins on which the yarn is being wound, said bobbins being yieldingly pressed
toward the rolls and rotated by the frictional contact of the accumulations of yarn
on the paper cop tubes placed upon said bobbins with said driving-rolls. The rolls
are affixed to shafts, which may be rotated by any suitable means. The bobbins
are supported and pressed inwardly toward the driving-rolls by pivoted holders
hereinafter described, which are acted on by weights to give the desired pressure
of the yarn wound on the tubes placed on said bobbins, against the driving-rolls.
Reciprocating yarn-guides deliver the yarn to the cop tubes, there being a guide
for each tube, as usual in this class of machines. Each guide is or may be an arm
having a yarn-receiving slot in its outer end.
In carrying out my invention, I divide the yarn-guides into two or more groups
or gangs, the guides comprising each gang being rigidly connected so that they
move in unison, while each gang is movable independently of the adjacent gang.
Machines of this character are usually of considerable length, so that in a machine
of ordinary length there is room for several gangs, an even number being preferably
employed.
In the simplest construction of the machine, two gangs of yarn-guides are
employed, and for the sake of convenience I will describe the machine as having

page_text: $
'
:
two gangs, although it will be obvious that a much larger number of gangs may be
employed.
=
The guides of each gang are attached to a sliding frame or carriage which is
movable on fixed guide-rods. Said carriage may be of any suitable construction,
and may be composed of two cross-heads having sockets in their end portions
formed to slide on the rods and side bars, secured by set-screws to the cross-heads.
The yarn-guides have base plates which are securely bolted to the side bars.
I have
used eight yarn-guides (four on a side) grouped on one frame or carriage, but the
number of guides in a gang may obviously be greater or less.
My invention, includes the provision of means for moving the two gangs simul-
taneously in opposite directions, and for simultaneously reversing their movement,
so that the shock or jar which attends the reversal of the movement of the yarn-
guides when all the guides are connected in a single gang is avoided, the stoppage
of the movement of each gang being neutralized by the stoppage of the movement
of the other gang.
Said
To this end, I provide two operating cams, one for each gang, the acting parts of
cach cam being the sides of a cam-shaped groove which receives a stud or trundle-
roll on the corresponding yarn-guide carriage, one cam being engaged with the
carriage of one gang, and the other with the carriage of the other gang. The cams
are affixed to a shaft, which is continuously rotated by any suitable means.
cams are formed so that each imparts a reciprocating movement to the gang of
guides with which it is connected, the arrangement of each being the reverse of that
of the other, so that while one cam is moving one gang in one direction, the other
cam is moving the other gang in the opposite direction. The cams are also arranged
so that the movement of the two gangs will be reversed simultaneously, thus
neutralizing the stoppage of the movement of one gang in one direction by the
stoppage of the movement of the other gang in the opposite direction, the result
'being a very marked increase in the steadiness of the running of the machine, and
a marked decrease of noise, wear, and strain, as compared with machines in which
all the yarn-guides are grouped in one gang all moving in the same direction.
I prefer to provide the carriage of cach gang of guides with two springs, which
act alternately in yieldingly opposing the movement of the carriage as it approaches
the ends of the movement, and thus preventing a blow of the trundle-roll against
the outer side of the cam-groove when the movement is reversed. The said springs
are attached at their outer ends to fixed supports on the frame of the machine, and
at their inner ends to the cross-heads or other suitable parts of the yarn-guide
carriage. One spring is extended by the latter part of the movement of the yarn-
guide carriage in the one direction, and thus presses the trundle-roll against one
projecting side of the cam when the movement of the carriage is being reversed.
The other spring is extended by the latter part of the movement of the carriage in
the opposite direction, and presses the trundle-roll against the other projecting side
of the cam during the next reversal of the movement, hence there is no objectionable
noise or rattle when the movement is reversed.
It will be seen that the springs act alternately, one spring being slack when the
other spring is under tension, and vice versa, so that there is no interference with
the action of either spring by the other.
When a cylindrical cop is employed, an ordinary form of holder for said cop may
be employed, said holder comprising two angular side pieces connected by a pivot
rod to fixed supports on the frame and connected to each other by a cross-bar.
The upper ends of the vertical arms of said side pieces havé bearings for the dummy
bobbin, and the weights are suspended by rods from the horizontal arms.
When a conical cop is employed, I prefer to support the same in a holder of
improved construction adapted to permit the ends of the cop to move independently
toward and from the accompanying driving-roll, so that the axis of the cop may
stand more or less obliquely to the axis of the said driving-roll. The said. holder
may consist of two base sections having ears which are mounted to turn on a pivot
rod, each having a vertical arm supporting one end of the bobbin, and a horizontal

page_text: arm supporting one of the weights. The arm which supports the smaller end of the
bobbin has a bar which projects across the space between the arms and extends
behind the inner edge of the other arm which supports the larger end of the bobbin.
This construction permits the smaller end of the cop to move outwardly faster than
The bar enables
the larger end, each end being always under the same pressure.
both sections to be moved outwardly together, when it is desired to displace the
holder and separate the mass of yarn from its driving-roll, the arm of one section
having a handle by which said section may be swung outwardly, and when this is
done the same movement is imparted to the arm of the other section by the bar.
A sufficient space is left between the bar and the arm behind which it projects to
prevent the bar from bearing on the arm during the winding operation. There
may be a latch on the holder adapted to engage a fixed rod on the frame of the
machine, to secure the holder in its displaced position.
A bobbin formed by cross-winding yarn ou a conical cop increases more
rapidly at the smaller end of the cop than at the larger end; and I have found that
if the ends of the cop are not independently movable the mass of yarn will be wound
unevenly, giving the periphery a wavy or corrugated appearance. By the sectional
construction of the holder above described, the winding is made uniform, so that the
mass presents a symmetrical periphery.
I do not limit myself to the described details of construction and relative
arrangement of parts, as the same may be variously modified without departing
from the spirit of my invention. The springs may be differently arranged, and may
act by compression instead of by extension. While said springs are very desirable
for the purpose of diminishing the noise attending the operation of the machine, it
will be seen that the advantage gained by the operation of the gangs of yarn-
guides by two oppositely acting cams moving the gangs simultaneously in opposite
directions is not dependent on the springs.
I do not claim the construction of the yarn-guides herein described, as the same
is not of my invention. may use any other suitably constructed yarn-guide, such
'as a wire arm bent to form a slot or eye through which the yarn may pass.

Improvements in Machines for Winding Yarns or Threads.
1, SAMUEL HEY of 56 Low Street Keighley in the County of York, Patent
Agent, do hereby declare the nature of this invention, as communicated to me
from abroad by William Anthony Smith of Lawrence, in the County of Essex and
State of Massachusetts, United States of America, Gentleman, and in what manner
the game is to be performed, to be particularly described and ascertained in and by
the following statement.:-
This invention relates to machines for forming accumulations of thread upon
spools or cop-tubes, either straight or conical, by the operation of cross-winding;
that is to say, feeding the yarn to a continuously rotating spool or tube by means
of a reciprocating or traversing yarn-guide. In organised machines of this
character a large number of spools or tubes are wound simultaneously, requiring
the use of a large. number of yarn-guides, and mechanism for reciprocating the
same. In many spooling machines now in use, a series of yarn-guides extending
the entire length of the machine are connected in one gang, all moving simul-
taneously and all arrested simultaneously at the end of the movement in each
direction, so that the reversal of the movement is attended with considerable jar,
involving wear and strain of the machine, as well as a very objectionable noise and
rattle. In other machines now in use, each guide is moveable independently of all

page_text: being very noisy when in operation.
Cxpensive, besides
My invention has for its object to provide a machine of this character in which
the objectionable features above mentioned shall be eliminated, so that the machine
will run without objectionable shocks or jars and with the minimum noise. The
invention also has for its object to enable the accumulation of yarn on a conical
cross-wound spool or tube to be more evenly and uniformly wound from end to end
than heretofore.
To these ends, the invention consists in the improvements which I will now
proceed to describe, and claim..

rolls a and rotated by the frictional contact. of the accumulations of yarn on the
paper cop-tubes b' placed upon said bobbins with said driving-rolls. The rolls a
are affixed to shafts a' a', which may be rotated as indicated by the arrows in
Figure 3, by any suitable means. The bobbins are supported and pressed inwardly
toward the driving-rolls by pivoted holders hereinafter described, which are acted
on by weights c c to give the desired pressure of the yarn wound on the tubes placed
on said bobbins, against the driving-rolls.
Each

tubes, there being a guide for each tube, as usual in this class of machines.
guide is here shown as an arm having a yarn-receiving slot d in its outer end.
In carrying out my invention, I divide the yarn-guides into two or more groups
or gangs arranged end to end, so that the guides of the several gangs collectively
constitute a series extending throughout the length of the machine, the guides
comprising each gang being rigidly connected so that they move in unison, while.
each gang is movable independently of the adjacent gang. Machines of this
character are usually of considerable length, so that in a machine of ordinary
length there is room for several gangs, an even number being preferably
employed.
In. the simplest construction of the machine, two gangs of yarn-guides are
employed; and for the sake of convenience, I will describe the machine shown in
the present case as having two gangs, although it will be obvious that a much
larger number of gangs may be employed.
The guides of each gang are attached to a sliding frame or carriage which is
movable on fixed guide-rods e e, the carriages being arranged end to end. Said
carriages may be of any suitable construction, and each is here shown as composed
of two cross-heads 22 having sockets in their end-portions formed to slide on the
rods e e, and side-bars 3 3 secured by set-screws 44 to the cross-heads. The yarn-
guides have base-plates d which are securely bolted to the side-bars 3. I have
here shown eight yarn-guides (four on each side) grouped on one frame or carriage,
but the number of guides in a gang may obviously be greater or less.
My invention includes the provision of means for moving the two gangs

page_text: simultaneously in opposite directions, and for simultaneously reversing their
movement, so that the shock or jar which attends the reversal of the movement of
the yarn-guides when all the guides are connected in a gang extending the entire
length of the machine is avoided, the stoppage of the movement of each gang
being neutralized by the stoppage of the movement of the other gang.
To this end, I provide two operating cams ff, one for each gang, the acting
parts of each cani being the sides of a cam-shaped groove which receives a stud
or trundle-roll f' on the corresponding yarn-guide carriage, one cam being engaged
with the carriage of one gang, and the other with the carriage of the other gang.
The cams are affixed to a shaft which is continuously rotated by any suitable
means. Said cams are formed as shown in Figures 2 and 4, so that each imparts a
reciprocating movement to the gang of guides with which it is connected, the
arrangement of each being the reverse of that of the other, so that while one cam
is moving one gang in one direction, the other cam is moving the other gang in the
opposite direction. The cams are also arranged so that the movement of the two..
gangs will be reversed simultaneously, thus neutralizing the stoppage of the
movement of one gang in one direction by the stoppage of the movement of the
other gang in the opposite direction, the result being a very marked increase in
the steadiness of the running of the machine, and a marked decrease of noise, wear,
and strain, as compared with machines in which all the yarn-guides are rigidly
connected in one gang extending the entire length of the machine.
I prefer to provide the carriage of each gang of guides with two springs hh',
which act alternately in yieldingly opposing the movement of the carriage as it
approaches the ends of its movement, and thus preventing a blow of the trundle-
roll against the outer side of the cam-groove when the movement is reversed.
The said springs are attached at their outer ends to fixed supports i i on the frame
of the machine, and at their inner ends to the cross-heads 2 2 or other suitable
parts of the yarn-guide carriage. The spring ¹ is extended by the latter part of
the movement of the yarn-guide carriage in the direction indicated by the arrow
in Figure 4, and thus presses the trundle-roll against the projecting side
the car when the movement of the carriage is being reversed. The spring his
extended by the latter part of the movement of the carriage in the opposite
direction, and presses the trundle-roll against the projecting side x of the cam
during the next reversal of the movement, hence there is no objectionable noise or
rattle when the movement is reversed.
It will be seen that the springs
of
act alternately, the spring being slack
when the spring is under tension, and vice versa, so that there is no interference
with the action of either spring by the other.
When a cylindrical cop is employed, an ordinary form of holder for said cop
may be employed, such for example as that shown in Figure 7 and at the right-
hand portion of the machine in Figure 3, said holder comprising two angular side-
pieces connected by a pivot-rod k' to fixed supports on the frame, and connected
to each other by a cross-bar . The upper ends of the vertical arms of said side-
pieces have bearings for the dummy bobbin b, and the weights c are suspended -by
rods c' from the horizontal arms.
When a conical cop is employed, I prefer to support the same in a holder of
improved construction adapted to permit the ends of the cop to move independently
toward and from the accompanying driving-roll a, so that the axis of the cop may
stand more or less obliquely to the axis of the said driving-roll. The construction
of the said holder is clearly shown in Figures 6 and 8, the holder consisting of two
base sections m m' having ears which are mounted to turn on a pivot-rod-m², each
having a vertical arm m³ supporting one end of the bobbin , and a horizontal
arm m supporting one of the weights c. The arm m, which supports the smaller
end of the bobbin, has a bar m³ which projects across the space between the arms
and extends behind the inner edge of the other arm me which supports the larger end
ol the bobbin. This construction permits the smaller end of the cop to move
outwardly faster than the larger end, each end being always under the same

page_text: pressure. The bar m' enables both sections to be moved outwardly together, when
it is desired to displace the holder and separate the mass of yarn from its driving-
roll, the arm m³ of the section m¹ having a handle m³ by which said section
may be swung outwardly; and when this is done, the same movement is imparted
to the arm m of the other section by the bar m³. A sufficient space is left
between the bar m³ and the arm behind which it projects, to prevent the bar
from bearing on the arm during the winding operation. m is a latch on the
holder adapted to engage a fixed rod m10 on the frame of the machine to secure
the holder in its displaced position.
A bobbin formed by cross-winding yarn on a conical cɔp increases more
rapidly at the smaller end of the cop than at the larger end, and I have found
that if the ends of the cop are not independently movable, the mass of yarn will
be wound unevenly, giving the periphery a wavy or corrugated appearance. By
the sectional construction of the holder above describel, the winding is made
uniform, so that the mass presents a symmetrical periphery.
I do not limit myself to the described details of construction and relative
arrangement of parts, as the same may be variously modified without departing
from the spirit of my invention. The springs h h may be arranged to act by
compression instead of by extension. While said springs are very desirable for
the purpose of diminishing the noise attending the operation of the machine, it
will be seen that the advantage gained by the operation of the gangs of yarn-
guides arranged end to end as described, by two oppositely acting cains moving
the gangs simultaneously in opposite directions, is not dependent on the springs.
I do not claim the construction of the yarn-guides here shown and described,
as the same is not of my invention. I may use any other suitably constructed
yarn-guide, such as a wire arm bent to form a slot or eye through which the
yarn may pass.
I am aware that the yarn-guides of a spooling-machine have been divided into
two independently movable gangs arranged side by side, one including all the
guides at one side of the machine and the other all the guides at the opposite
side of the machine, said gangs being moved simultaneously in opposite directions.
My arrangement differs from that last mentioned, in that the guides are divided
across the machine into gangs arranged end to end instead of being divided
Jengthwise of the machine into gangs arranged side by side. The short gangs
arranged end to end are much lighter than the elongated gangs arranged side by
side, so that when the gangs are oppositely reciprocated, as described, the
machine ruus much more smoothly and with less strain and wear than would be
the case if the gangs extended lengthwise of the machine.
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. A spooling-machine comprising in its construction a plurality of gangs of
yarn-guides arranged end to end, one gang being movable independently of another,
and mechanism for oppositely re-iprocating said gangs to neutralize the jar caused
by the reversal of their movement, as set forth.
2. In a spooling-machine, the combination of two gangs of yarn-guides arranged
end to end, each gang being movable independently of the other, and two oppositely
arranged cams, one engaged with one gang and the other engaged with the other
gang, said cams being formed to move the two gangs simultaneously in opposite
directions and to simultaneously reverse their movement, as set forth.
3. A spooling machine comprising in its construction a plurality of gangs of
yarn-guides arranged end to end, mechanism for independently reciprocating said
gangs and for simultaneously reversing their movement, and alternately acting
springs applied to each gang, one spring acting during one reversal of movement
while the other spring acts during the other reversal of movement.
4 A spooling-machine comprising in its construction two gangs of yarn-guides

page_text: arranged end to end, each gang being movable independently of the other, two
oppositely arranged cams engaged with said guides, and two springs acting to
yieldingly oppose the movement of said gangs in one direction, and two other
springs acting to yieldingly oppose the movement of the gangs in the opposite
direction, as set forth.
5. A spooling-machine comprising in its construction a supporting frame having
fixed guides, two carriages arranged end to end movable on said guides, each
carriage supporting a gang of yarn-guides, and two oppositely arranged cams
engaged with projections or trundle-rolls on said carriages, said cams being formed
to move the two carriages simultaneously in opposite directions and to simultaneously
reverse their movement, as set forth.
6. In a spooling-machine, the combination of two independently movable
carriages arranged end to end, each having a gang of yarn-guides, two oppositely
arranged cams engaged with trundle-rolls or projections on said carriages, and two
springs engaged with each carriage, one opposing the latter part of the movement
of the carriage in one direction while the other opposes the latter part of the
movement of the carriage in the other direction, as set forth.
7. In a spooling-machine, the combination with a friction driving-roll and a
traversing yarn-guide, of a holder composed of two sections independently pivoted
to fixed supports, each section having a weight whereby it is pressed inwardly, one
section having a bar projecting behind the other section and adapted to impart an
outward movement to the latter, as set forth.
Dated this 6th day of December 1894.
