Improvements in Machines for Winding Thread, Yarn, and like
Materials.
1, THORVALD HANSEN, Mechanic, of 21 West First Street, Boston, Massachusetts,
United States of America, 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 relates to an improved winding machine or apparatus of the kind or
class adapted for winding thread, yarn or like material upon a cop tube or cylinder,
and has for its object to provide a simple and efficient machine of that kind capable
of running at a substantially high speed and of producing a maximum number of
balls of thread or yarn in a minimum time. My improved machine, as herein shown,
is provided with two cop shafts, which are positively driven at a substantially high
speed as will be described, independent reciprocating thread guides co-operating with
the cop shafts, and a single cam actuating the said thread guides. The reciprocating
thread guides are mounted as herein shown in rotatable carriers, as will be described,
which co-operate with an automatic stopping mechanism to be hereinafter described;
and the said cam shaft is driven from the main shaft, as herein shown, by means of a
belt encircling a preferably tapering pulley on the main shaft and a tapering pulley
on a counter shaft, which latter shaft is geared to the cam shaft as will be described.
The belt referred to, is adapted to be moved longitudinally or axially on the tapering
pulleys so as to vary the speed of reciprocation of the thread guides according to the
size of the thread being wound.
These and other features of this invention will be pointed out in the claims at the
end of this specification.

page_text: Referring to the drawings, A represents a suitable table, foundation or base to
support the operative parts of the machine, the said table being represented as
mounted upon a supporting stand or pedestal A¹, which may be of any suitable or
desired construction. The table or base A, in the present instance, is shown as
having erected upon it three transversely arranged uprights A2, A3, A4, secured to
the base as by screws or bolts A³. The uprights A³ A support in suitable bearings
at their upper end, two cop shafts a a¹ (see Figs. 1, 2 and 5), the said shafts at their
front ends being made of reduced diameter to receive upon them cop tubes or
cylinders a², upon which the thread or other flexible cord is wound. The cop shaft a,
as herein shown, has fast upon it between the uprights A³ A4, a gear a³, which meshes
with a like gear at on the shaft a¹, and the cop shaft a has mounted upon it a normally
loose pulley a constituting, in the present instance, the movable member of a clutch
mechanism, which co-operates with a disk or stationary member fast on the said
shaft. The normally loose pulley a5 is provided, as herein shown, with a hub a',
which is loosely fitted upon the reduced portion of a sleeve a keyed on the cop
shaft a and provided with an annular groove a, into which extends the end of a
cam-shaped portion a10 of an arm a¹² (see Figs. 2 and 6), forming part of a sleeve or
hub a13, loose on a stud or pin ¹ extended from the upright A³. The sleeve a³ is
movable in one direction to engage the normally loose pulley a" with its co-operating
disk a³, by a spring a encircling the cop shaft a between the sleeve a* and a
collar a fast on the shaft. a. The normally loose pulley a³ is adapted to be driven
from a main shaft, not herein shown, by means of a belt, not shown, but which
passes about the pulley a³, and the rotation of the cop shaft a produces rotation
of the cop shaft a¹, but in an opposite direction. The cop shafts a and a¹ are
adapted to have fitted upon their reduced end portions the cop tubes or cylinders a²
upon which the thread is wound, and the said shafts have co-operating with them
two thread guides 6 61, herein shown as two uprights or arms, provided at their
upper end with notches 62, and erected from plates 63, 64, movable in guideways
in rotatable carriers represented as plates or bars 60 (see Figs. 1, 2 and 4),
arranged substantially parallel with the axis of the shafts a a₁ and secured to
suitable frames revolubly mounted upon the bearings 2-3, for a cam shaft 67, the
said bearings projecting from the uprights A2 A3. The thread guide carrier 6' is
fastened at its opposite ends, as herein shown, to two cranks or arms 60, 610, loosely
mounted upon the bearings 2-3, on opposite sides of a cam hub 612, provided with
a suitable cam groove 613 for producing the desired reciprocation or traverse of the
thread guides b 6¹. The thread guide carrier 66 is also secured at its opposite ends,
as herein shown, to two like cranks or arms 614 615 loosely mounted on the bearings 2-3,
and the cranks or arms 6° 61° of the thread guide carrier b' have extended from them
substantially at right angles thereto, arms 620 621, (see Figs. 2 and 4) connected
together, as herein shown, by a tie bar or rod 622, upon which is loosely mounted a
depending rod 623 extended down through the table or base A, as herein shown, and
provided at its lower end with a weight 624, which serves to keep the thread guide b
up in contact with the ball of thread as it is being formed. The cranks or arms b₁4 615
supporting the thread guide carrier 68, have extended from them substantially at
right angles thereto, like arms 620 627 joined by a tie bar or rod 628, upon which is
loosely hung a rod 620 carrying a weight 630. The weights 624 630 serve to keep
the thread guides 66' in proper position with relation to the thread being wound
upon the cop tubes on the shafts a a¹, the thread guides being gradually forced
back away from the cop shaft as the ball is formed, thereby lifting the said weights.
The carriers 6 6 for the thread guides are provided with suitable slots 640 of
substantially the same length as the width of the cam hub 612, and the slide
plates 63 64 are provided on their underside with suitable pins or projections, which
extend into the cam groove 613, the said pins or projections being not herein shown
as they are well understood. The cam shaft is driven from the cop shaft a in a
manner as will now be described. The cop shaft u, at its rear end, has fast upon
it a pulley c which is connected by a belt c¹ to a pulley c², revolubly mounted
on a stud or shaft c³ on an arm c² of a hub c³, provided with an arm co extended,

page_text: as shown, at an angle to the arm ct, and provided with a slot c7, indicated by
dotted lines in Fig. 3, through which is extended a clamping screw or bolt c*,
which is extended into the upright A4 and serves to secure the pulley carrying
arm c in its adjusted or proper position. The hub of the pulley c² is provided
with a pinion clo (see Figs. 2 and 6), which meshes with a substantially large
gear cl2 fast on the cam shaft b7.
From this construction, it will be seen that rotation of the cop shaft a produces
rotation of the cam shaft bi by means of the pulley c, belt c', pulley c², pinion c¹º and
gear 12. The supporting arm ct for the pulley shaft is adjustable in the arc of a
circle with the cam shaft 67 as a center, so that, the pulley c² may be moved away
from the pulley c in order to take up any slack in the belt c'. The pulleys c c²
preferably are slightly tapering in opposite directions, as shown in Figs. 1 and 2, so
that, speed of rotation of the cam shaft may be changed to regulate the rate of
travel or reciprocation of the thread guides 6 61 according to the size of thread to be
wound upon the cop tubes. To effect this change of speed, the belt c' is movable over the
palleys which is effected by means of a belt-shipping mechanism, herein shown as a
forked arm & secured to or forming part of an internally threaded collar d' (see dotted
lines, Fig. 1), which is mounted upon a screw rod d² having its inner end reduced in
diameter to form a shoulder, and supported in the upright. A and a depending
bracket d secured to the said upright, the shoulder on the screw-threaded rod d²
bearing against the bracket d, when the screw rod is turned to produce travel of the
threaded collar d¹ and of the shipper d. The inner end of the rod d² is reduced again to
form a second shoulder which bears against the upright A', and the said end is screw-
threaded to be engaged by a lock nut 40 countersunk into the upright as indicated by
dotted lines, Fig. 2. The shipper arm d is guided in its travel by means of a guide
rod d' attached to the bracket d and extended through the said shipper arm. The
machine herein shown is provided with an automatic stopping mechanism consisting
of two connected members, either of which is adapted to effect the stopping of the
machine, as will now be described. The carrier for the thread guide b co-operates
with one member of the automatic stopping mechanism, which member consists, as
herein shown, of a hub or sleeve e (see Figs. 15, and 6), loosely mounted on a stud or
pin e extended from the upright A³, the said hub or sleeve being provided at or near
its opposite ends with two cranks or arins e2, 3, the crank or arin e being extended
upward and provided with a horizontal extension carrying an adjusting screw et. The
carrier for the thread guide b¹ has co-operating with it the other member of the
automatic stop mechanism, which consists of a hub or sleeve e (see Figs. 2, 5 and 6)
mounted on a stud or pin e' projecting from the uprights A3, the said sleeve having
at or near its opposite ends two upright cranks or arms es, e, the crank or arm e
having a substantially horizontal extension carrying an adjusting screw 10 (see
Fig. 2). The cranks or arms e² e³ on the sleeve e extend in substantially the same
direction for a purpose as will be described. The crank or arm es is provided, as
herein shown, with a notch e¹2 (see Fig. 6), which is adapted to be engaged by a tooth
or projection e3 on the hub or sleeve a¹³, and the said hub or sleeve has fast to it,
one end of a spring e15 having its other end fastened to the upright A3 or to a stationary
part of the frainework, the said spring being coiled so as to normally turn the sleeve
or hub 13 in the direction indicated by the arrow 20, in Fig. 6, which movement, on
the part of the hub a¹³, would cause the cam portion of the crank or arm a¹² to
move up into the groove a³ in the clutch hub or sleeve a³, and thereby nove the said
sleeve and the loose pulley a5 toward the right, viewing Fig. 1, against the action of
the spring 5, and thus withdraw the loose pulley a5 from the stationary disk or
member of the clutch on the shaft a. The hub a3 of what may be termed the
starting mechanisin for the clutch is provided, as herein shown, with an arm f having
a segmental brake-shoe f, which is adapted to be engaged with the sleeve as by the
time the loose pulley has been disengaged from the stationary disk aº, so as to stop
rotation of the cop shaft a², which is practically the main shaft for the machine
herein shown. The spring e15 tends to move the hub or sleeve 13 in the direction
indicated by arrow 20, Fig. 6, and when the machine is in operation, with the loose

page_text: pulley a5 in engagement with the stationary disk, the hub a¹³ is held from
being turned by the spring e15, by the latch or projection e¹³ engaging the notch e¹² in
the crank or arm es (see Fig. 6), which latter is held up in engagement with the said
latch by a spring f2 connected to the crank or arm e³, and, as herein shown to a
screw f30 inserted into the sleeve e.
In order that the single clutch mechanism may be automatically operated by
either of the stopping devices, the crank e² of one member of the automatic stopping
device is connected to the crank or arm es of the other member, by a link f³. By
this means, it will be seen that, when the crank or arm e³ is moved back by the
carrier for the thread guide b, the crank e² being extended substantially opposite to
the crank or arme will move in the opposite direction to the crank or arm e³,
namely, in the direction indicated by the arrow 40, Fig. 6, and by means of the
link, will positively disengage the crank or arm es from the locking projection or
latches on the hub a¹3; while if the crank or arm e of the other member of the
automatic stopping mechanisin is engaged by the carrier for the thread guide b',
both cranks ees will move in the same direction, and the crank or arm e³ is moved
directly backward in the direction indicated by arrow 40, so as to release the hub a"
and permit the spring e15 to disengage the loose pulley and, at the same time, apply
the brake. The machine herein shown and described is simple in construction and
is especially designed for high speed, and in practice, the thread has been wound
with the cop shafts run at a very high speed, namely, thousands of revolutions to
the minute.
In the machine herein shown, balls of varying sizes may be wound at the same
time, if so desired, by changing the position of the adjusting screws e, e10. so that
one member of the automatic stopping mechanism may be operated upon, when its
ball has reached the desired diameter, which is less than that of the ball partially
wound upon the other cop tube, and after the finished ball has been taken off from
its cop shaft, a new cop tube or cylinder may be placed on the cop-shaft
and the machine again started to finish the ball partially wound and to
commence winding a new ball on the shaft from which the finished 'ball has just
been taken. I prefer to make the pulleys c c² slightly tapering, but it is evident that
the pulleys may be made of like diameter throughout and such a machine could be
used for one diameter of thread and would be useful on account of the increased
output or production. The machine may be started by means of a handle g (see
Fig. 6) attached to the hub a¹³.
The cop tubes a² may and preferably will be held on the cop shafts a a¹, by means
of the devices herein shown, and each consisting of a sleeve g¹ adapted to fit over
the end of its cop shaft and provided with a pin g5 on its inner side (see Fig. 4),
which is adapted to engage a suitable cam or locking slot or groove go in the cop
shaft, the sleeve 94 being provided with a milled collar g7.

invention and in what manner the same is to be performed I wish it to be
clearly understood that I am aware that many thread-winding machines have hereto-
fore been devised, and I am also aware of the Specifications of Patents No. 6381 of
