Improvements in Means or Apparatus for Winding Thread
or Yarn.
ALFRED BRYANT MORSE, of South Easton, in the State of Massachusetts,
one of the United States of America, Manufacturer do hereby declare the nature
of this invention to be as follows:-
In a large and important class of thread winding apparatus the thread or yarn
is wound upon rotatably supported spindles or tubes, rotation being transmitted
thereto by means of suitable drums upon which they rest.
The thread or yarn led from suitable sources is delivered to the spindles by
guides which are reciprocated in the direction of the length of the spindles, to
traverse the yarn or thread thereupon, so that the same is laid in more or less
compact and even masses.
The speed with which such apparatus can be run is practically limited by the
speed of the reciprocation of the traverse mechanism, and as such mechanism is
heavy the momentum thereof prevents very high speed.
In winding such thread masses the rolling over of the endmost spirals must be
carefully guarded against in order to produce compact solid masses which can
afterwards be unwound over one end without catching, and where the traverse of '
the thread guide is not absolutely accurate and exact, the thread will fall over at
the ends of the mass, making poor work.
When the traverse mechanism is speeded up beyond a certain point the momentum
of the moving parts comes into play, and the sudden change of direction at each
end of the stroke will not be uniform and the result will be uneven winding.
In other words, there is an uncertainty and vibration at such points, so that the
thread guides cannot produce accurate work, and the wound masses will in
consequence be rough, and over-run at the ends.
This invention has for its object the production of a thread winding apparatus
which can be run at a very high speed without detriment to the work produced,
and to attain this object, the thread guides are mounted upon a light, yet strong,
carrier, preferably flexible and preferably maintained under tension with means for
reciprocating said carrier and the guides thereon in the direction of the length of
the spindles or tubes upon which the thread is to be wound.
By thus making the carrier extremely light, it may be reciprocated at a high
rate of speed without undue momentum or jar, and by maintaining it taut or under
tension, it is kept as rigid as though it were sufficiently heavy to itself remain rigid
under all conditions.
A driving drum for driving the cops or balls of thread being wound by frictional
contact with said drum is provided, the latter being provided with end flanges which
prevent falling over of the thread windings at the ends of the mass, these drums,
for the best results, being made longitudinally adjustable for the purpose of
varying the distance between their respective end flanges, for varying lengths of
thread masses.
A thread support above the reciprocating carrier and provided with pins or
projections supported by a distance less thau the length of the throw of said thread
guide or carrier and between which the thread for a guide is passed to prevent the

page_text: thread over running or falling over at the end of the mass of thread, should the
thread become disengaged from the notch or eye of the thread guide.
These pins or projections operate to stop the traverse of the thread before
the thread guide changes its motion.
A frame of suitable shape supports the operative parts of the apparatus, and has
bearings for parallel drum shafts and having secured thereto driving drums.
Gears are fixed on the shafts, the gear being connected by intermediate gears to
another gear on the main driving shaft, while an intermediate connects gear and
the drum shaft gear.
Standards erected on the frame may carry bearings, for the journals of a
drum, having a diameter about equal to the distance between the paths of the two
thread guide carriers, the face of the drum having a cam groove therein, having a
long, gradual sweep and to impart a comparatively short throw.
The cam shaft may have fast thereon a gear in mesh with an intermediate gear,
mounted on one of the standards, and driven through the gear from the driving
shaft, though obviously a separate gear could be secured to the driving shaft, if
desired, to operate the cam shaft.
The speed of the cam may be varied relative to the speed of the driving drums
by changing gear.
Stands erected on the main frame at opposite sides of the cam drum are
horizontally recessed, to receive respectively preferably flat slide bars, on which
are mounted roller or other studs which enter the cam groove.
Cover plates retain the slide bars in their bearings, the slide bars moving in
parallel vertical planes adjacent to the paths of movement of the thread guides.
Two parallel bars supported in standards, form bearings for a series of arms,
said arms receiving rotatably therein at or near their free ends the journals of
the spindles, tubes or other foundations upon which the thread or yarn is to be
wound.
The spindles, or foundations upon which the thread or yaru masses are wound,
rest upon and are rotated by the drums and as the thread increases in diameter the
pivotal spindle support permits it to rise from the drum.
I prefer to make the drum independently secured to the drum shaft by suitable
set screws so that the drums can be adjusted to the length of the spindles or to
the masses of thread to be wound thereupon.
When the thread is laid upon the spindle, layer by layer, the endmost turns have
a tendency to fall over, and by erecting upon the ends of the drums upturned lips
or flanges, from an eighth to a quarter of an inch in height, for instance, such
support is given to the end turns that they will not fall over.
When several layers have been superposed, one upon another the end support is
unnecessary, but it is of very great assistance in producing the best thread masses
to support the ends of the few layers nearest the surface during the winding.
A series of brackets are mounted on and along the sides of the main frame,
preferably between the drums, the upper ends of said brackets extending above
the drums and in front of the line of contact of the spindles therewith, the brackets
being recessed or grooved to form bearings for the thread guide carrier.
The carrier I prefer to use is a thin, flat strip or ribbon of sheet metal resting
in and longitudinally movable in the bearings wherein they are retained by caps
bolted to the brackets, said caps being provided with suitable devices to hold a
common thread-support, such as sheet or cast metal and alternately a light rod or
wire above the path of the guide carrier, or equivalent devices.
The apron or shelf is bent or curved in the direction of its length at its outer
edge and overhangs the carrier and at its ends is notched to engage pins on
the caps.
The upper surface of the thread support is preferably polished to offer little
resistance to the thread as it comes from the source of supply and passes over the
guide shelf.
A series of thread guides are suitably secured to the carrier each guide being

page_text: according to one form a piece of sheet metal upturned at its inner end and notched,
said upturned end projecting between the adjacent spindle and the thread support
and somewhat above the latter.
The thread as it passes over the support enters the notch of its guide, and travels
thence to the spindle, to be wound thereupon, the thread guide being reciprocated
by its carrier in the direction of the length of the spindle to traverse the thread
thereupon.
To facilitate the entrance of the thread to the notch the upper edge of the
notched end of the guide is convexed, so that the thread can easily slide up into
the notch, while the common thread support keeps the threads froin resting upon
and becoming soiled or greasy hy contact with the carrier whose bearings, of any
suitable construction, will be maintained well lubricated.
The carrier is very light, and the addition of the thread guides thereto does
not increase its weight very much, so that it may be reciprocated at very high
speed without any of the evil effects due to momentum with a heavy traverse
mechanism.
Owing to its flexibility and light weight the carrier is preferably made as a
tension member. and while under tension is reciprocated.
Various modifications of the means for maintaining the tension of the carrier
and for reciprocating it with its thread guides may be employed.
The metallic straps or bands at front and back of the apparatus as bent and
connected to the slide bars the opposite ends of the carriers being attached to
preferably stout leather straps which are passed around guide rolls rotating on
vertical axes, the straps at the end of the machine farthest from the transverse
cam being connected preferably by a spring sufficiently strong to keep the carriers
under tension at all times, it being obvious that practically the same result is thus
attained as would be by using two cams, one at each end of the carrier.
The mechanism at the cam end of the apparatus is different, the carriers having
attached thereto leather straps which pass around rolls said straps being secured to
a slide bar longitudinally movable in bearings if desired carrying the roll or stud
which enters the cam groove of the cam so that the two carriers located at the
front and back of the apparatus are oppositely reciprocated, to traverse the thread
upon the spindles.
The guide carriers can be moved in opposite directions by the co-operation of
the cam groove with the rolls, the latter being located at opposite sides of the
cam drum.
The spring exerts a pull upon the carriers at all times, and thereby keeps them
under tension, so that the thread guides move in a plane just as they would were
they mounted on the heavy, rigid traverse bars now in use.
The carrier bearings may be made anti-friction in any of the well known ways,
by rolls, balls, lubricant, etcetera, as desired, and the speed with which the thread
guides may be reciprocated is unlimited, so far as the momentum of the carriers
and attached parts is concerned.
The thread supports between the supporting brackets may be provided with
upright pins or projections separated by a distance less than the length of the mass.
of yarn to be wound, said pins acting as guards for the thread and preventing it
from running over the ends of the mass on the spindles should the thread be
disengaged from the notches of the thread guides, said stops also preventing the
thread from over-running laterally onto the caps or brackets.
Alternatively the drum shafts are supported in bearings and are provided with
gears respectively, the one gear being connected by intermediate gears to a gear on
the main driving shaft, a single intermediate gear connecting the driving gear and
the drum shaft gear.
A bevel gear on the main shaft meshes with a similar gear fast on a short
vertical shaft which has secured at its upper end a second bevel gear meshing with
a similar gear on a shaft supported in bearings on the frame, a suitable cam for
actuating the traverse mechanism being secured to the said shaft.

page_text: Parallel bars supported in standards form bearings for the spindle or tube
supporting arms.
One end of each carrier may be provided with a roll to engage cams respectively,
the other ends being bent around guide rolls and connected by a spring, the cams
being so set that the carriers will be oppositely reciprocated.
Or the opposite ends of the carriers may be connected by springs to the ends of
a pivoted yoke.
While it is preferable, on the ground of economy and simplification of con-
struction, to connect the two carriers at the front and back of the apparatus, as
described, yet the carriers may be operated independently, as they would be in an
apparatus having a single series of spindles.
The carrier may be provided at one end with a roll or stud to be engaged by a
cam, the other end being connected by a spring to a rod carrying a roll or stud
in engagement with a second cam the spring maintaining the tension of the
carrier.
A spring or springs may maintain the carrier tension, and with the light weight
of the reciprocating portions of the traverse mechanism the thread guides will
have exactly the same stroke no matter whether the speed be moderate or very
high, as the evil effects due to momentum of heavy reciprocating parts have been
eliminated by the construction herein described.
The thread support may be wire held in suitable seats in the caps above the path
of the thread guide carrier.
The pins are so located that just before the thread guide approaches the
extremes of its throw the thread is brought against them, and as the guide
continues its movement the thread in the notch thereof is carried against that side
of the said notch which is at the rear thereof in the direction of movement of the
guide, thus putting an extra amount of tension on the thread, so that when the
motion of the thread guide is reversed, the contact of the thread with the said side
of the guiding notch is maintained during the first part of the said reverse motion,
thus obviating any slack winding or throwing over of the thread due to lost motion
by or through the guide.

Improvements in Means or Apparatus for Winding Thread
or Yarn.
I ALFRED BRYANT MORSE of South Easton, in the State of Massachusetts,
one of the United States of America, Manufacturer do hereby declare the
nature of this iuvention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
In a large and important class of thread winding apparatus the thread or yarn
is wound upon rotatably supported spindles or tubes, rotation being transmitted
thereto by means of suitable drums upon which they rest.
The thread or yarn led from suitable sources is delivered to the spindles by

This invention has for its object the production of a thread winding apparatus
which can be run at a very high speed without detriment to the work produced,
and to attain this object my invention comprehends the mounting of the thread

thread being wound by frictional contact with said drum, the latter being provided
with end flanges which prevent falling over of the thread windings at the ends of
the mass, these drums, for the best results, being made longitudinally adjustable for
the purpose of varying the distance between their respective end flanges, for varying

length of the throw of said thread guide or carrier and between which the thread
for a guide is passed to prevent the thread over running or falling over at the end

These pins or projections operate to stop the traverse of the thread before the
thread guide changes its motion.

page_text: Referring to Figs. 1 and 2, the frame A* of suitable shape to support the
operative parts of the apparatus, has bearings 20, 21 for parallel drum shafts a
and b, arranged at the back and front of the apparatus, and having secured thereto
like driving drums A and B.
Gears a*, bx are fixed on the shafts a, b, respectively, the gear being con-
nected by intermediate. gears 30 and 40 to a gear m on the main driving
.shaft M, driven in any suitable manner, in the direction of arrow 300, Fig. 1,.
while an intermediate 45 connects gear m and the drum shaft gear a*.
Standards erected on the frame carry bearings M1, M2, for the journals N¹ of a
drum N, having a diameter about equal to the distance between the paths of the
two thread guide carriers, to be described, the face of the drum N having a cam
groove N therein, having a long, gradual sweep and to impart a comparatively
short throw.
As herein shown the cam shaft N' has fast thereon a gear N2 in mesh with an
intermediate gear N³, mounted on one of the standards, as M* see Fig. 1, and
driven through the gear 45 from the driving shaft M though obviously a
separate gear could be secured to the driving shaft, if desired, to operate the
cam shaft.
By substituting in usual manner, change gears of different diameter for those
shown, the speed of the cam may be varied relative to the speed of the driving
.drums.
Stands n and o, see Fig. 2, erected on the main frame at opposite sides of the
cam drum N are horizontally recessed, as shown in Fig. 24, to receive respectively.
preferably flat slide bars n*, ox, on which are mounted roller or other studs n¹, o¹,
which enter the cam groove Nx, see Fig. 2.
Cover plates 2, 02, retain the slide bars n*, ox, in their bearings, as clearly
shown in section in said Fig. 24, the slide bars moving in parallel vertical planes
adjacent to the paths of movement of the thread guides at the front and back of
the apparatus.
Two parallel bars P, Q, are supported in standards 180 above the centre of the
apparatus and forming bearings for a series of arms p', q', respectively, said arms
receiving rotatably therein at or near their free ends the journals of the spindles,
tubes or other foundations t* upon which the thread or yarn is to be wound.
The spindles, which term will be hereinafter used as indicating the foundations
upon which the thread or yarn masses are wound, rest upon and are rotated
by the drums A, B, one spindle being herein shown as resting on each drum, and
as the thread increases in diameter the pivotal spindle support permits it to rise
from the drum.
1 prefer to make the drum, as best shown in Fig. 10, in two parts 10, 12,
independently secured to the drum shaft by suitable set screws 31 and 32, so that
the drums can be adjusted to the length of the spindles or to the masses of thread
to be wound thereupon, the flanges serving to guide and control the building of
the thread at the ends of the mass.
When several layers have been superposed, one upon another the end support is
unnecessary, but it is of very great assistance in producing the best thread masses
to support the ends of the few layers nearest the surface during the winding.
A series of brackets 20 are mounted on and along the sides of the main frame,
preferably between the drums, the upper ends of said brackets extending above the
drums and in front of the line of contact of the spindles therewith, the brackets
being recessed or grooved at f21, see Fig. 8, to form bearings for the thread guide
carrier.
I have herein shown the carrier I prefer to use as a thin, flat strip or ribbon of
sheet metal h, resting in and longitudinally movable in the bearings f" wherein
they are retained by caps f" bolted to the brackets, said caps being provided with
suitable devices to hold a common thread-support, shown in Fig. 8 as sheet or
cast metal 10, and in Fig. 9 as a light rod or wire k above the path of the guide
carrier.

page_text: The apron or shelf k is bent or curved at k" in the direction of its length at
its outer edge and overhangs the carrier h, and at its ends is notched, as at k¹³,
Fig. 8 to engage pins f3 on the caps f22.
I prefer to polish the upper surface of the thread support 10, to offer little
resistance to the thread t as it comes from the source of supply T and passes over
the guide shelf T¹.
A series of thread guides are suitably secured to the carrier h, each guide being
shown in Figs. 1, 2 and 8 as a piece of sheet metal g upturned at its inner end and
notched, as at g', said upturned end projecting between the adjacent spindle t* and.
the thread support ko and somewhat above the latter.
The thread t as it passes over the support ko enters the notch gl of its guide,
and travels thence to the spindle, to be wound thereupon, the thread guide being
reciprocated by its carrier h in the direction of the length of the spindle to traverse
the thread thereupon, and from Fig. 1 it will be seen that the path of the thread
guide is very close to the line of contact between the driving drum and the
particular mass of thread wound thereby.
To facilitate the entrance of the thread to the notch g' the upper edge of the
notched end of the guide is convexed, as at 92, so that the thread can easily slide-
up into the notch, while the common thread support keeps the threads from resting
upon and becoming soiled or greasy by contact with the carrier h, whose bearings,
of any suitable construction, will be maintained well lubricated.
The carrier his very light, and the addition of the thread guides g thereto does
not increase its weight very much, so that it may be reciprocated at very high.
speed without any of the evil effects due to momentum with a heavy traverse
mechanism.
The small cross sectional area of the carrier incidental to its thin, ribbon like.
character, as herein shown, renders it necessary, in order that it may be reciprocated:
longitudinally, that it be acted upon at each end by a pulling force, said pulling
forces operating alternately in opposite directions, and as the carrier is thus
flexible it is operated as a tension member.
Several means are herein shown for maintaining the tension of the carrier and
for reciprocating it with its thread guides.
In Fig. 2 i have shown the metallic straps or bands at front and back of the.
apparatus as bent and connected to the slide bars n*, ox, the opposite ends of the
carriers being attached to preferably stout leather straps which are passed
around guide rolls h2, h3, rotating on vertical axes, the straps at the end of the
machine farthest from the transverse cam N being connected preferably by a
spring S, sufficiently strong to keep the carriers under tension at all times, it being.
obvious that practically the same result is thus attained as would be by using two
cams, one at each end of the carrier.
In Figs. 3 and 4, the mechanism at the cam end of the apparatus is different,
the carriers h having attached thereto leather straps 10 which pass around
rells 2, 3, said straps being secured to a slide bar A, longitudinally movable in
bearings 70 and 80, and shown as carrying the roll or stud 15 which enters the
cam groove 120 of the cam C2 so that the two carriers located at the front and
back of the apparatus are oppositely reciprocated, to traverse the thread t upon
the spindles t*.
In Fig. 2 it is obvious that the guide carriers will be moved in opposite
directions by the co-operation of the can groove N* with the rolls n', o¹, the.
latter being located at substantially diametrically opposite sides of the cam
drum N.
The spring S, Figs. 1 and 4, exerts a pull upon the carriers at all times, and.
thereby keeps them under tension, so that the thread guides y move in a plane just
as they would were they mounted on the heavy, rigid traverse bars now in use.
The carrier bearings may be made anti-friction in any of the well known ways,.
by rolls, balls, lubricant, etcetera, as desired, and the speed with which the thread
.

page_text: guides may be reciprocated is unlimite 1, so far as the momentum of the carriers
and attached parts is concerned.
As most clearly shown in Fig. 8 the thread supports 10 between the supporting
brackets, are provided with upright pins or projections separated by a
distance less than the length of the mass of yarn to be wound, said pins acting as
guards for the thread and preventing it from running over the ends of the mass on
the spindles should the thread be disengaged from the notches g' of the thread
guides, said stops also preventing the thread from over running laterally onto the
caps or brackets.
The general operation of the mechanism shown in Figs. 3 and 4 so far as the
winding of the yarn or thread is concerned, is substantially such as shown in
Figs. 1 and 2, but the arrangement of the actuating gears for the drum is somewhat
different.
In said Figs. 3 and 4, the drum shafts a0, 60, are supported in bearings 5 and 6
and are provided with gears a0, 610, respectively, the gear a being connected by
intermediate gears 2 and 3 to a gear c on the main driving shaft C, and rotated in
the direction of the arrow ex, Fig. 3, a single intermediate gear 4 connecting the
driving gear c and the drum shaft gear 40
A bevel gear e on the shaft C meshes with a similar gear c², see dotted lines
Fig. 3, fast on a short vertical shaft c³, which has secured at its upper end a second
bevel gear meshing with a similar gear e ou a shaft C' supported in bearings 7
and 8 on the frame, a suitable cam C for actuating the traverse mechanism being
secured to the said shaft C¹.
In Figs. 3 and 4, said cam is shown as provided with a groove 120 of such shape
as to reciprocate a roller or other stud 15 between the bearings 7 and 8.
The parallel bars d aud e supported in the standards 18 form bearings for the
spindle or tube supporting arms d' and el.
In Fig. 6 I have shown one end of each carrier, as m10, m1, provided with a
roll to engage cams m100, m150, respectively, the other ends being bent around guide
rolls m200 and connected by a spring S', the cams being so set that the carriers will
be oppositely reciprocated.
The same arrangement as to driving cams 100, 150, is shown in Fig. 7, but the
opposite ends of the carriers no, no, are connected by springs s, s¹ to the ends of a
yoke y pivoted at y¹ to a suitable support, not shown, as Figs. 5 to 7 inclusive are
intended only to show broadly the arrangement of the traverse mechanism, the
drums D being shown as ordinary cylinders.
While it is preferable, on the ground of economy and simplification of con-
struction, to connect the two carriers at the front and back of the apparatus, as
described, yet the carriers may be operated independently, as they would be in an
apparatus having a single series of spindles, one such construction being shown in
Fig. 5.
In said fig., the carrier 10 is provided at one end with a roll or stud ol to be
engaged by a cam 20 the other end being connected by a springs to a rod carrying
a roll or stud 80 in engagement with a second cam o, the spring maintaining the
tension of the carrier ou.
In all cases I prefer to employ a spring or springs to maintain the carrier tension,
and with the light weight of the reciprocating portions of the traverse mechanism
the thread guides will have exactly the same stroke no matter whether the speed
be moderate or very high, as the evil effects due to momentum of heavy
reciprocating parts have been eliminated by the construction herein described.
In Figs. 3 and 4 and in Fig. 9, I have shown the thread support as a wire k,
held in suitable seats in the caps f above the path of the thread guide carrier h.
My invention is not restricted to the construction and arrangement herein set
forth, as alterations and modifications may be made therein without departing from
the spirit and scope of my invention.
The pins are so located that just before the thread guide approaches the
extremes of its throw the thread is brought against them, and as the guide continues

page_text: its movement the thread in the notch thereof is carried against that side of the
said notch which is at the rear thereof, in the direction of movement of the guide,.
thus putting an extra amount of tension on the thread, so that when the motion of
the thread guide is reversed, the contact of the thread with the said side of the
guiding notch is maintained during the first part of the said reverse motion, thus
obviating any slack winding or throwing over of the thread due to lost motion.
