PROVISIONAL SPECIFICATION.
Improvements in Machines for Winding or Spooling Yarn or
Thread.
A communication from abroad by JOHN WILMARTH FOSTER, of Springfield,
County of Hampden, State of Massachusetts, one of the United States of
America.
I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane, in the County of
Middlesex, Patent Agent do hereby declare the nature of this invention to be as
follows:-
The machine herein to be described is adapted to wind yarn or thread of any and
all kinds upon conical cop tubes as well as upon cylindrical cop tubes.
When the yarn is to be wound upon a conical cop tube, the conical roll or shaft
carrying the tube is rotated by the action against the cop tube of a cone driving
drum, composed essentially of a shaft having fixed collars adapted to rest upon and
be rotated by a rotating drum, the said shaft having between its fixed collars and
loosely mounted on it a series of rings, which are driven only by the friction of the
shaft against the interior of the rings, the surface speed of the said rings so loosely
mounted upon their driving shaft being the same as the surface speed of the conical
cop tube of
yarn thereon.
Another feature of my invention comprehends a spooling machine containing a
shaft provided with driving wheels or discs; a shell roll surrounding the same and
provided with a spiral groove at its periphery, the said groove receiving a stud or
projection of a traverse guide, which moves the traverse to lay the yarn upon the
cop tube of whatever forin used.
Another feature of this invention comprehends a spooling machine containing a
shaft driving wheels or dises thereon; a shell roll detached from the said wheels
or discs but surrounding them, the interior of the shell roll resting by gravity upon
the exterior of the wheels or discs; a shoe or lifting device to lift the shell roll
from contact with the wheels or discs when the rotation of the shell roll is to be
stopped; a traverse mechanism actuated by grooves in the shell roll; a yoke to
receive and make pressure upon the shaft carrying the cop tube; and an inter-
mediate roll to be acted upon by the shell roll and acting to rotate the cop tube;
and connections between the yoke and the shoe referred to, to move the same
automatically when the cop tube has been properly filled, to thus effect the stopping
of the rotation of the cop tube.

Improvements in Machines for Winding or Spooling Yarn or
Thread.
A communication by JoHN WILMARTH FOSTER, of Springfield, County of
Hampden, State of Massachusetts, one of the United States of America.
I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane, in the County of
Middlesex, Patent Agent 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 :-
The machine to be herein described is adapted to wind yarn or thread of any and
all kinds, upon conical cop tubes and also upon cylindrical cop tubes.

page_text: When yarn or thread is being wound upon a conical cop tube, the conical roll or
shaft carrying the conical cop tube is rotated by the action against it of a conc
driving drum, and it will be understood that the surface speed of the cop tube, and
the mass of yarn on it, is faster where the tube and yarn load is of greatest diameter;
and where a solid roll or drum is used to rotate the cop tube or yarn load, the
friction upon the yarn or thread is made to vary considerably.
To overcome this friction and strain upon the yarn due to variation in surface
speed of different parts of the conical mass of yarn or thread being wound constitutes
one object of this invention.
In accordance with the invention to be herein claimed, the cone driving drum or
roll is composed of a shaft having fixed collars adapted to rest upon and be rotated
by a main rotating shell roll or drum, the said shaft having between its fixed collars
and loosely mounted thereon, a series of rings which are driven only by the friction
of the shaft against the interior of the rings, the surface speed of the said rings
so loosely mounted upon their driving shaft, being the same as the surface speed
of the yarn on the conical cop tube at the point where the said rolls touch the
same during the winding operation.
One part of this invention therefore consists in a spooling machine including as
operative parts thereof a conical roll to carry a conical cop tube to receive yarn or
thread to be wound, a rotating shell or drum, and an intermediate sectional roll to
drive the conical roll, the said intermediate roll having loose rings driven only by
friction, whereby the surface speed of the rolls is kept in unison with the surface
speed of the mass of yarn being wound at the point where each loosely mounted
ring of the roll contacts with the yarn load, as will be set forth.
Another feature of this invention comprehends a spooling machine containing
a shaft provided with driving wheels or disks, a shell roll surrounding the same
loosely and provided with a spiral groove at its periphery, the said groove
receiving a stud or projection of a traverse guide, which causes the said guide
to lay the yarn or thread upon the cop tube or shell of whatever form used.
Another feature of this invention comprehends a spooling machine containing a
shaft provided with with driving wheels or disks, a shell roil, the interior of which
rests by gravity upon the exterior of the said wheels or disks, a shoe or lifting
device to lift the shell roll from contact with the said wheels or disks when the
rotation of the said shell roll is to be stopped, a traverse mechanism actuated by
grooves in the shell roll, a yoke to receive and make pressure upon the shaft
carrying the cop tube to be wound with yarn or thread, and an intermediate roll
acted upon by the shell roll, and in its rotation made to rotate the roll carrying the
cop tube, and connections between the yoke and the shoe or lifting device referred
to, to move the same automatically when the cop tube has been properly filled,
to thus effect the stopping of the rotation of the cop tube, as will be described.
Fig. 1. is a sectional detail partially broken out, shewing a sufficient portion of
a spooling machine to enable this present invention to be understood.
Figure 2 is a detail of the yoke and its connected rod by which to effect the
stopping of the machine when the cop tube being wound is of the proper size.
Fig. 3, 4 and 5, are details showing the traversing guide in different positions.
Fig. 6. is a sectional detail in the line X-X. Fig. 1., but enlarged, the parts
being in condition to wind a cop tube of conical shape.
Fig. 7 shows the conical roll detached and enlarged, the dotted lines showing a
conical cop tube thereon.
Fig. 8. an end elevation of the roll shown in Fig. 7.
Fig. 9, shows the intermediate cone driving drum or sectional roll.
Fig. 10. shows the yoke detached.
Fig. 11. is a modification enlarged showing the machine adapted to wind a
cylindrical cop tube or equivalent spool.
The framework A has suitable sills A' running lengthwise thereof, on which are
mounted suitable stands a.
The shaft, having suitable bearings on the frame-work and driven in any usual

page_text: manner and from any suitable source, has a pulley e, which by a band extended
over a pulley, rotates the shaft el, the said shaft having attached to it one or
more wheels or disks e.
The wheels or disks e are surrounded loosely by a metallic shell roll or drum h
the inner diameter of which is some little greater than the external diameter of the
wheels e, see Fig. 6. so that when the weight of the shell roll, rests upon the upper
portions of the wheels, then the said wheels in their rotation will rotate the shell-
roll, but when the shell roll is lifted slightly so as to break the contact between its
interior and the wheels e, then the shell roll will remain at rest notwithstanding the
wheels e continue to rotate.
Depending from the frame-work or sills are bearings 16 for a rock shaft 7 having
an arin 18, on which is pivotally mounted a shoe or lifting device m, represented as
having a concaved face."
The shaft 7 has at one end a hand lever n, and at its other end a weight 8, which
when the machine is in operation occupies the position represented in Fig. 6, and
acts normally to keep the shoe or lifting device from contact with the shell roll,
the weight at such time coming against a suitable stop.
The shaft 7 has fast upon it a disk having two prongs n² & n³, located in different
vertical planes, the prong n³ having a laterally projecting end, as best represented
in Figure 1.
The stands a receive within them the legs of a yoke a', the said yoke being
grooved to receive the journals a' of the conical roll p, upon which in practice will
be placed any usual or suitable conical cop tube to receive the yarn or thread to be
wound, the yoke being adapted to bear with its weight upon the journals of the
said roll and keep the roll or the material thereon down upon the cone driving
drum or sectional roll interposed between it and the shell roll, the said cone driving
drum or sectional roll being represented as composed of a shaft h*, two fixed
collars, and a series of loose rings 0.
As the diameter of the roll or mass of yarn being wound thereon increases,
the weight and roll are elevated, and at the proper time a projection or shoulder
near the lower end of a rod n' connected to the yoke a', strikes the projection n³
referred to, and starts the rock shaft 7 50 that the arm 18 thereupon puts the
shoe or lifting device m in contact with the shell roll, and the latter as soon
as it is engaged by the lifting device continues the movement of the lifting
device in the direction of rotation of the shell roll, turning the rock shaft 7 a
little farther and carrying the weight 8 to the other side of a vertical line
intersecting the shaft 7, such movement of the rock shaft and its attached lifting
device effecting the lifting of the shell roll from contact with the wheels e, and
immediately thereafter the rotation of the shell roll is stopped, and consequently
the rotation of the devices lying upon it.
As has been stated, the surface speed of a conically wound mass of yarn or
thread is greatest where the diameter of the mass is greatest, and therefore to
rotate such a mass of yarn with the least possible strain and friction, the device
engaging the yarn should have the same surface speed.
In practice the collars of the cone driving or sectional roll rest directly
upon the shell roll and are rotated thereby, but the loose rings are rotated
only by the friction between them and the shaft *, so that the said rings
contracting with the mass of yarn, may be rotated at the same surface speed
as that of the yarn or thread with which they are in contact, the rings slipping
more or less upon the shaft *.
The yarn or thread to be wound may be taken from bobbins, spools, cops or
otherwise, as represented at the upper part of Fig. 1, and the said thread or yarn
must be traversed in order to lay it properly from end to end of the cop tube.
To do this I have provided the machine with suitable tracks 4, upon which I
have mounted a suitable traverse guide 4, the same having at its underside a
swiveling stud of usual shape, which stud enters a spiral or crossing groove made

page_text: in the periphery of the shell roll, the forward end of the guide having a suitable
opening to receive and deliver the yarn or thread.
Instead of the cone roll 1 may use any usual cylindrical roll and may provide it
with any usul cop tube or receiver for yarn or thread.
I have shewn but one set of devices for winding one yarn, but in practice the
machine may have any number of devices such as described to wind any desired
number of yarns or threads.
The cone driving roll made in sections as described, might be used to very
great advantage even with a solid drum such as now commonly employed in spooling
machines.
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 I do
not broadly claim a roll having a traversing groove to move a thread guide, nor do
I claim a drum eut entirely through and provided with a
itself receives the yarn and acts as a traverse guide but what a slit, which slit
do claim is :
1. A spooling machine including as operative parts thereof a conical roll to
carry a conical cop tube to receive yarn or thread to be wound, a rotating
shelf or drum, and an intermediate sectional roll to drive the conical roll, the said
intermediate roll having loose rings driven only by friction whereby the surface
speed of the rolls is kept in unison with the surface speed of the mass of yarn being
wound at the point where each loosely mounted ring of the roll contacts with the
yarn load, substantially as described.
2. A spooling machine containing a shaft provided with driving wheels or disks,
a shell roll surrounding the same loosely, and provided with a spiral groove at its
periphery, the said groove receiving a stud or projection of a traverse guide which
causes the said guide to lay the yarn or thread upon the cop tube or shell of what-
ever form used, substantially as described.
3. A spooling machine containing a shaft provided with driving wheels or disks,
a shell roll, the interior of which rests by gravity upon the exterior of the said
wheels or disks, a shoe or lifting device to lift the shell roll from contact with the
said wheels or disks when the rotation of the said shell roll is to be stopped, a
traverse mechanism actuated by grooves in the shell roll, a yoke to receive and
make pressure upon the shaft carrying the cop tube to be wound with yarn or
thread, and an intermediate roll acted upon by the shell roll, and in its rotation
made to rotate the roll carrying the cop tube, and connections between the yoke
and the shoe or lifting device referred to, to move the same atomatically when the
cop tube has been properly filled, to thus effect the stopping of the rotation of
the cop tube, substantially as described.
