Improvements in Means or Apparatus for Spooling or Winding, or
for Doubling or Twisting and Spooling or Winding, Yarn or
Thread.
A communication from abroad by JOHN WILMARTH FOSTER, of Westfield,
Hampden County, State of Massachusetts, in the United States of America,
Manufacturer.
I Alfred GEORGE BROOKES of 55 & 56 Chancery Lane, in the County of
London Chartered 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 :-
This invention has for its object the improvement of that class of machine
employed to wind thread or yarn on a shell of any shape, either conical or
cylindrical, said shell being preferably of paper.
I have herein illustrated my invention as adapted to twist together two threads
contained on cops taken directly from the spindles on which the threads were
wound as they were spun, and the said threads are shewn as being wound directly
upon a conical shell, the rotation of the shell being effected by a driving roll resting
on a rotating drum, the driving roll having co-operating with it a lifting device
under the control of a stop motion mechanism adapted to be actuated by a drop wire
when the thread breaks, the lifting device lifting the driving roll from the drum,
thus stopping the rotation of the driving roll and shell.
The drum is suitably grooved to effect the reciprocation of a thread guide to
thus lay the thread on the shell from end to end.
One part of this invention consists in the use with a rotating drum, a suitable
thread guide, and a driving roll rotated by said drum and adapted to rotate a shell
by friction against it; of a lifting device acting against the driving roll, a drop
wire, and stop motion devices between said drop wite and lifting devices to cause it
to lift the driving roll and stop the rotation of the shell when a thread breaks,
substantially as will be described.
Also in the use of a shell-holder composed of a spindle having two bearings for
the shell, a dog mounted on one of the bearings, and a dog actuator to automatically
actuate the dog to engage or disengage the shell as required, substantially as will
be described.
Also in the use in a spooling machine, of a rotating hollow spindle having an
attached plate provided with two or more stationary spindles to contain cops of thread
in the condition in which they were spun and wound; a traversing thread-guide, a
rotating drum; a driving roll to rotate a shell, a spindle to carry a shell, a support
for the spindle carrying the shell, and a stop motion mechanism carried by the
hollow spindle, said stop motion mechanism including drop levers for each thread, a
rod extended through the hollow spindle and a device for separating the plate
referred to from its driving device whereby the twisting of the threads is obviated
on the breaking of either of said threads before they are twisted together,
substantially as will be described.
Also in the use of a spooling machine with a rotating drum and driving roll to
rotate a shell frictionally, of a rotating plate having a series of spindles fixed thereto
and adapted to receive cops of thread, the rotation of the plate twisting together
the threads carried by the spindles while the drum and winding roll effect the
winding of the doubled and twisted threads on the shell, substantially as will be
described.
Also in the use in a spooling machine having a rotating drum, a shell driving roll

page_text: rotated thereby, and reciprocating thread-guide, of a rotating plate having spindles
fixed to it and carrying cops of yarn, a hollow spindle connected with said plate, a
stop motion rod extended through said hollow spindle, drop levers adapted to
operate said rod, and a lifter actuating said rod to stop the twisting together of the
said threads when broken, substantially as will be described.

Fig. 9 is a section of Fig. 7 in the line a³.
A represents part of the frame-work of a spooling machine, A¹ a shaft mounted
in suitable bearings therein and provided with a spindle driving drum A² to rotate
the band A³.
The band A³ is extended about a pulley A fast on the sleeve of a friction
'wheel A mounted loosely on a stud A held in a stand A' connected to a portion
of the framework in suitable manner.
spun
The friction wheel A5 engages frictionally and rotates the plate B having fixed
'to it two spindles B₁ adapted to receive upon them cops B or wound masses of
yarn is
yarn taken directly from a spinning machine in which the
and wound.
The table B has fitted to its hub a tubular spindle B³.
This spindle at its upper end carries a disk B₁ to which is secured the pivots of
drop levers a, having at their ends suitable hooks or eyes to engage the threads a¹
coming from the cops B2, the said drop levers being normally held up in the position
shewn in Fig. 2 when the threads are unbroken.
The table has as its pivot a hollow stud B having its foot extended through a
part of the frame-work and part of the stand A' where it is held in position by
a suitable nut a², the said stud near its lower end having a tubular passage-way a³
through which is extended a finger a fixed to a rod a extended through said
spindle B and said sleeve, the upper end of said rod having mounted upon it a
metal washer a provided, see Fig 2, with suitable stop pins, the said metal washer
having above and in contact with it a felt or other friction washer a', and above the
friction washer is one or more nuts a³.
:
The finger a enters a notch in a lifting device b, shewn in section in Fig. 2, and
in elevation in Fig. 44, said lifting device being mounted loosely upon a suitable
set screw b¹ in the stand 'A'.
F
This lifting device is made as a circular block cut away for a portion of its
periphery to leave corners 2, 2, so that when the said lifting device is turned in one
or the other direction about the said stud screw, one of the corners will act against
the under side of the plate B and will lift the same slightly on the stud B
sufficiently to break the driving contact between the friction pulley A' and the
'said plate.
Whenever, in the operation of the machine, one of the threads a¹ break, the
'outer or heavier end of the drop levér a, drops, letting its inner end rise, thus
putting the said drop lever in position to, in its rotation of the spindle B³, strike
one of the pins of the washer as and turn the rod a sufficiently to cause the finger a¹

page_text: to turn the lifting device band stop, as described, the rotation of the plate B and
spindles B¹.
In this operation, the washer a may drag, if need be, on the felt or other
frictional washer a', the threads a twisted together passing through the eye b* and
over the bar 6 through a drop wire 6, said drop wire being herein shown as a piece
of wire, one end of which is connected with a rock-shaft or bar suitably mounted
at its ends in a part of the framework.
The framework has erected upon it a stand C, the upper end of which forms
part of a friction joint, the other part being a disk-like portion C³, the two parts
being held together by a suitable bolt C³.
The part of the friction joint has a hollow slot 3 into which is entered a
rod C³ provided at its free or.left-hand end, see Fig. 1, with a bifurcated portion C+
having suitable bearings for the journals of a spindle D.
The rod C³ is confined in place by a set screw 4, and the portion C₁ of the support
for the spindle D is connected with the rod C³ so as to swivel or pivot, see Fig. 5^,
so that the shell, to be described, whatever its shape, whether conical or tubular,
may rest directly upon the driving roll c having its journals supported in suitable
bearings c¹ forming part of the frame-work and resting upon and adapted to be
rotated by the drum E, said drum, the shaft of which is mounted in suitable bearings,
having its periphery provided, as herein represented, with a crossing groove e to
receive a suitable foot or projection extended from a thread-guide el into said groove,
said thread-guide being adapted to slide to and fro on a guide e parallel to the
shaft E' of the said drum, the crossing groove causing the thread-guide to traverse
back and forth and lay its thread upon the shell D'.
The journals of the driving roll c are located just above the upper end of a lifting
device F composed of two like uprights connected to a lever pivoted at 4, see
Fig. 1, said lever having a suitable cam surface at 5 which is adapted to be acted
upon by the lower end of a legf pivoted at f¹ upon a stand f' forming part of the
frame-work.
This leg has pivoted upon it at its lower end a leg lever 6 having near its outer
end a projection 7 crossed by the drop wire be, the drop wire, when elevated by a
thread, resting above or close to the said projection.
The inner end of this leg lever 6 is normally below the teeth of a constantly-
rotating ratchet wheel 8 fast to a shaft 10 which may be rotated intermittingly in
any usual or desired way.
Whenever the thread drops, upon which hangs the drop wire 66, the said drop
wire, acting on the pin 7 of the leg lever, lifts the opposite end of the leg lever into
the path of rotation of the teeth of the ratchet wheel 8, and one of the teeth.
striking the end of the leg lever, moves it to the left, viewing Fig. 1, causing the
leg to act on the cam surface of the lever F1 forming part of the lifting device,.
causing the said lever to be turned about its pivot 4, and the bar F to rise and
acting upon the journals of the driving roll lift it from contact with the drum, thus
stopping the rotation of the driving roll and the shell D' resting thereon.
the
The spindle D has near its journals or ends suitable conical bearings g, g²,
one 9' having a shoulder g to form a stop for the large end of the shell D',
supposed to be of paper, and herein represented as conical.
But if the shell were cylindrical, then the bearings y, g¹ would be cylindrical and
of the same size.
The larger bearing g' has pivoted upon it at 12 like dogs 13 represented as
toothed at 14 and slotted at 15 for the reception of dog-actuators 16, shewn as
screws, extended through the bearing and into a sort of nut 17.
To fasten the shell D₁ upon the spindle D, the attendant will push the shell upon
the spindle, the latter being removed from its support C4, and while holding in one
hand the shell and in the other hand the nut 17, will turn one or the other so as to
cause the screw 16 in the slots of the dogs referred to, to move the toothed portions
of the dogs outwardly to engage with the interior of the shell.
These dogs hold the shell firmly in place on the spindle.

page_text: By reversing the movement of the parts, the dogs may be made to release the
shell.
The parts C' of the joint referred to carries a spring connected to the part 3
by a screw, the said portion being hooked to engage a projection 20 of the
stand C when the support C is lifted away from the driving roll, as the operator
sometimes wishes to do especially when the spindle D is being put into or to be
taken from the support.
Under the term "cop" I intend to include any wound mass of yarn such as
commonly produced by the operation of spinning.
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 use in a spooling machine with a rotating drum having crossing grooves;
a suitable thread-guide, and a driving roll rotated by said drum and adapted to
rotate a shell by friction against it; of a lifting device acting against the driving
roll, a drop wire, and stop motion devices between said drop wire and lifting devices
to cause it to lift the driving roll and stop the rotation of the shell when a thread
breaks, substantially as described.
2. The use in a spooling machine, of a shell-holder composed of a spindle having
two bearings for the shell, a dog mounted on one of the bearings, and a dog actuator
to automatically actuate the dog to engage or disengage the shell as required,
substantially as described.
3. The use in a spooling machine, of a rotating hollow spindle having an attached
plate provided with two or more stationary spindles to contain cops of thread in the
condition in which they were spun and wound; a traversing thread-guide; a
rotating drum; a driving roll to rotate a shell, a spindle to carry a shell, a support
for the spindle carrying the shell, and a stop motion mechanism carried by the hollow
spindle, said stop motion mechanism including drop levers for each thread, a rod
extended through the hollow spindle, and a device for separating the plate referred
to from its driving device whereby the twisting of the threads is obviated on the
breaking of either of said threads before they are twisted together, substantially as
described.
4. The use in a spooling machine with a rotating drum and driving roll to rotate
a shell frictionally, of a rotating plate having a series of spindles fixed thereto and
adapted to receive cops of thread, the rotation of the plate twisting together the
threads carried by the spindles while the drum and winding roll effect the winding
of the doubled and twisted threads on the shell, substantially as described.
5. The use in a spooling machine having a rotating drum, a shell driving roll
rotated thereby, and a reciprocating thread-guide, of a rotating plate having
spindles fixed to it and carrying cops of yarn, a hollow spindle connected with said
plate, a stop motion rod extended through said hollow spindle, drop levers adapted
to operate said rod, and a lifter actuating said rod to stop the twisting together of
the said threads when broken, substantially as described.
