I, ALFRED BRYANT MORSE, of 53, Leon Street, Boston, in the State of Massa-
chusetts, United States of America, Manufacturer, do hereby declare the nature of
this invention to be as follows:
My invention is an improved thread winding apparatus.
One object of my invention is to simplify and render more compact the thread
winding machine, while at the same time giving it a greater range of usefulness,
increased economy in running, and saving of power.
In machines as at present constructed, it is very awkward and usually impos-
sible to wind parallel or tubular quills, and also cone quills on the same machine
without practically reconstructing the machine for the purpose; accordingly
another object of my present invention is to provide simple means for changing
from winding a cone to winding a cylinder, or vice versa.
Again, in machines as at present constructed, a considerable number of adjust-
ments and additional or substituted parts must be had in order to materially
increase the length of cop or bobbin being wound; and therefore, a further object
of my present invention is to provide means whereby the machine may wind a
short cop (an inch, for instance) or may with equal facility wind a long one (ten
inches, for instance).
In order that my invention may be more fully apprehended, I will explain one
preferred embodiment thereof, although I wish it understood that I do not limit
my invention to any one mechanism, inasmuch as the latter may be infinitely
varied without departing from the main principles and features of my invention.
On a main shaft, I journal loosely the throw cam, in the raceway of which runs
the roll or lug of the slidebar carrying the thread guide.
The main shaft is geared by suitable speed changing mechanism, such as a cone
and belt, to a short countershaft mounted in the frame parallel to and adjacent the
main shaft, and the counter shaft is geared preferably through an idler back to
the throw cam, so that the latter, in this form of my machine, rotates in the same
direction as the main shaft, and thereby reduces the friction between the two.
I prefer to mount the thread guide on a stationary bearing (the novel feature
thereof being that it is in the form of thin, light tubing, sliding on a rod, and
simply having a lug travelling in a slot to maintain the proper direction of move-
ment) the quill spindle in such case being mounted on a swinging arm whose are
of movement preferably includes the eye or button of the thread guide, so that as
the thread mass is built up, thereby automatically moving the spindle away from
the path of movement of the thread guide, the eye or button of the latter main-
tains its line of movement relatively to the axis of the thread mass precisely where
it is needed in order to produce a compact and uniform thread mass.
The spindle instead of being held in immovable journals in the bearings, is
mounted in a bracket, which is journaled on a stud or post extending transversely

page_text: to the spindle axis, and itself journaled in the swinging arm or bracket which
supports the spindle and its operating mechanism.
From this construction it will be seen that the spindle and its bearings may
readily be adjusted into exact parallelism with the path of movement of the thread
guide for winding a parallel or cylindrical quill, or it may be readily adjusted
obliquely to said path of movement of the thread-guide when it is desired to wind
a cene, it being understood that the driving gear is rendered capable of being
changed to suit this change in the position or obliquity of the spindle.
In a machine of the kind above described, I find that it is advantageous to
relieve the pressure on the thread guide of the surface of the quill in winding,
which causes excess of friction against the thread guide; and accordingly I have
provided an arm carrying a pivotted finger or rod, which slides between automatic
gripping surfaces arranged to permit the rod to move freely one way, but prevent
it from moving in an opposite direction, so that thereby the spindle may be moved
away from the thread guide, but cannot swing towards it.
In connection with my improved machine as above described, it will be under-
stood that any usual kind of belt shifter is used, and that a suitable tension device
and stop motion will be employed.
In connection with the tension device, however, I employ a rack and pinion
movement, which also I regard as a novel feature of this invention, the advantage
of such a construction being that it gives me a wider range of adjustment than
is possible with the old lever tension device, inasmuch as it is a simple and
expeditious matter to change the pinion meshing with the rack bar in order to
adiust the tension for extreme ranges of work.
By having the throw cam mounted directly on the main shaft, it avoids having a
separate shaft for the cam itself, and therefore there is nothing in the way of the
cam, so that a cam of any desired size may be mounted on the shaft, there being
no parallel shaft adjacent to interfere.

Improvements in Thread Winding Apparatus.
I, ALFRED BRYANT MORSE, of 53, Leon Street, Boston, in the State of Massa-
chusetts, 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
des ribed and ascertained in and by the following statement:--
My invention is an improved thread winding apparatus.
One object of my invention is to simplify and render more compact the thread
winding machine, while at the same time giving it a greater range of usefulness
increased economy in running, and saving of power.
In winding machines of this type as at present constructed, it is very awkward
and usually impossible to wind parallel or tubular quills, and also cone quills on
the same machine without practically reconstructing the machine for the purpose.
Accordingly another object of my present invention is to provide simple means for
changing from winding a cone to winding a cylinder, or rice versa.
Again, in machines as at present constructed, a considerable number of adjust-
n: nts and additional or substituted parts must be had in order to materially
increase the length of cop or bobbin being wound; and, therefore, a further object
of my present invention is to provide means whereby the machine may wind a

page_text: short cop (an inch for instance) or may with equal facility, wind a long one (ten
inches, for instance).
In order that my invention may be more fully apprehended, I will explain one
preferred embodiment thereof, although I wish it understood that I do not limit
my invention to any one mechanism, inasmuch as the latter may be infinitely
varied without departing from the main principles and features of my invention.
In the drawings Fig. 1 is a front elevation of the complete machine, excepting
a suitable base or support;
Fig. 2 is a diagrammatic top or plan view illustrating the adjustment of the
machine for winding different forms of thread masses;
Fig. 3 is a right hand end elevation of the machine shown in Fig. 1;
Figs. 4 and 5 are respectively views in central longitudinal section, and end
clevation, of a detail of construction.
In suitable standards a, a, I journal a main shaft bf herein shown as provided
with usual fast and loose pulleys b', b, driven from a belt b
Between the standards and loosely journalled on the main or driving shaft b
between collars c, cl, is a throw-cam d, herein shown as having its hub
reduced,
as indicated by dotted lines at 2, to receive a driving gear e, secured thereto by
means of a set screw e¹.
The shaft bis provided with a suitable speed changing device, herein shown as
composed of cones f, f', belt f and belt shifter f³, all of any usual or preferred
kind, for suitably changing the speed to correspond to different requirements of the
work.
The pulley f is mounted on a counter-shaft journalled in the standard a', and
provided at its opposite end with a pinion g meshing with an intermediate gear
or idler g, geared in turn to the driving gear e of the throw-cam, it being under-
stood that the train of gear as thus arranged is provided for convenience in driving
the throw-cam, it being preferable that the latter should rotate in the same
direction as the main shaft. Loosely mounted on a fixed sleeve surrounding the
shaft b, between the standard a and a collar 2, is a bracket h having an extended
hub h, and split at its upper end to receive a spindle i, held in clamped position
by a bolt 2, this spindle being provided at its upper end with bearings,,
carried by a yoke rigid with said spindle.
In said bearings i,, is journalled the quill spindle k, having a gear k, fast
thereon between the bearings and driven from a gear 1, fast on the main
shaft, through an intervening idler journalled at in the bracket h.
Other gears may be substituted for the gear, the substitute gears having their
teeth formed at different angles in accordance with the angle at which the spindle ¿¹
shall be set.
The quill spindle is held in proper position adjacent the thread guide m by
means of a weight w, suspended from an arm w³, extended rearwardly from the
hub, Fig. 3.
I have arranged the thread guide m to reciprocate in a stationary bearing, it
being herein shown in the form of an arm carried by a thin tube m¹, Fig. 4,
mounted on a rod m³, fast in the frame of the machine, said tube being provided
with a stud or roll m³, travelling in the path of the throw-cam, and having an
proie lug m travelling in a slot or way m in the frame of the machine, for
man'a ning the proper direction of movement and keeping the thread-guide steady
and uniform in its operations.
The thread, twine or other material (Fig. 3) being wound, passes from any
usual source over rolls, and thence to the tension wheel and tension
mechanism, in connection with which I provide a rack bar, meshing with a
inion sleeved on the spindle of the tension, and having fast to it a dise
in turn provided with a pin, to which is attached one end of a strap 16,
running over and in contact with the hub of the tension wheel, and sustaining
at its end the weight.
It is desirable to put upon the thread as it passes to the quill a degree of tension

page_text: varying as the diameter of the mass upon the quill increases, and to do this the
thread is led over the grooved periphery of a tension wheel which is not
allowed to rotate absolutely freely, but is retarded to exert a friction upon the
thread.
To accomplish this retardation the strap designated by the letter 1 is led over
the hub of the tension wheel on the other side of the bearing supporting the
shaft of the tension wheel, and this strap is weighted. The friction of the strap
upon the hub acts to retard the tension wheel, and the retardation is in pro-
portion to the amount of the periphery of the hub covered by the strap, this being
governed by the position of the pin carried by the disc which has a pinion
rotatable by means of the rack bar 73, the latter being controlled by a lever w¹,
tatable about as the centre, and connected to the bracket so as to be
governed by the angular position of the latter.
As the thread mass upon the quill g increases in diameter, the bracket h, see
Fig. 3 will move to the left, the lever w will be raised, causing the rack bar p
to move upward, and, through the medium of the pinion, the disc will be
rotated in the direction of the hands of a watch and the pin 5 carried with it,
so that the length of strap bearing upon the periphery of the hub of the tension
wheel will be shortened, and accordingly the retardation of the tension wheel 72
will be lessened and the latter will rotate more freely with less friction upon the
thread t.
The rack bar is pivoted at 7 to the arm won the hub referred to.
I prefer a rack-bar and pinion for the reason that it is certain in its operation,
and permits of a wide range of movement for the different requirements of the
machine; it is a very simple matter to remove one pinion 7, and replace another
larger or smaller, but having the same pitch of teeth.
On the bar is mounted an adjustable stop s arranged to engage a usual stop
motion lever h8.
This lever is normally held in locking engagement with a rod 7 by a dog s
whose arms rests lightly on the thread t, so that when the latter breaks, the
dog will move the lever 48 sufficiently to disengage it from the rod and permit
the spring on the latter to shift the belt and stop the machine.
I find that in practice with a machine constructed, as described, the thread will
not wind properly, or at least it will not wind to the best advantage when the quill
is free to hear against the thread guide with the full force of the weight w, and
accordingly I have devised an automatic grip which relieves the pressure of the
thread guide, of the surface of the quill in winding, thereby preventing the excess
of friction which would otherwise prove seriously objectionable.
This automatic grip will be understood, viewing Fig. 3, where it will be seen
that I have provided a finger or rod r, pivotted at to the arm w¹, and held
and sliding in a passage provided in a bracket secured to the frame of the
machine.
is in
A lever, freely pivotted on a stud and preferably provided with a roll 5 at
its engaging end, rides against the finger r, being normally held in biting engage-
ment therewith by a spring in a cup » engaging the outer tree end of the lever.
Viewing Fig. 3, where the dotted line indicates the deal centre
position of the lever, it will be observed that this lever
a position to always permit the finger or
redz to move upwardly, but
to prevent its moving downwardly, and accordingly it will be understood that the
rod or finger is automatically gripped and held by the lever as the thread mass
increases on the quill, so that whatever outward movement is gained by the thread
mass moving away from the thread -uide, is held, and the quill is automatically
prevented from swinging back again towards the thread guide even to the minutest
degree.
I find that in practice the rapid rotation of the cop or thread mass acts to throw 5
the spindle and mass just far enough away from the thread guide and to give the
required ease of movement and this advantage is rever lost because the clutch 3

page_text: prevents any return of the mass into close contact with the thread guide. This
also prevents any rebounding of the thread mass, and proves of great advantage
in the practical running of the machine.
I have provided a bearing surface for the rod or finger r, which may be
delicately adjusted by means of the set screws.
As the thread muss builds up on the quill, the quill spindle and its support
swing away from the thread guide on the main shaft as a centre, and from this
explanation, and viewing Fig. 3, it will be readily understood that the eye or
button of the thread guide maintains its path of movement approximately in the
same plane relatively to and embracing the axis of the quill spindle, and by
reason of the fact that the arc of movement of the quill spindle is at substantially
the same radial distance from the main shaft as the delivery end of the thread
guide, it will be observed that I do not intend to vary the position of the thread
guide.
It will also be understood that when it is desired to wind any different form of
thread mass, or to wind a cylinder, it is a very simple matter simply to loosen the
clamping bolt h² and turn the quill spindle in its support so as to bring the
surface of the quill next the thread guide into parallelism with the latter.
Also it will be understood that the arrangement of parts as described enables
me very readily to change the throw-cam from the cam such as shown, to a larger
or smaller throw-cam, as may be desired, limited only by the dimensions of the
parts of the machine.
Inasmuch as the moving parts are much more compact and are simpler than
those heretofore provided, I am enabled to run the machine at a much higher
speed and obtain a largely increased output.
The slide bar for the thread guide, constructed as shown, is much cheaper,
lighter, and less liable to get out of order than the plate slide bars heretofore pro-
vided.
I do not intend to limit my invention to the precise details of construction
herein shown, but various changes and modifications may be made therein without
departing from the spirit and scope of my invention.
