drum. The present supply-holder is adapted for
use with practically all types of Winding and like 25
machines however, and thereforethe illustrated
machine will be described only briefly as relating
to the operation of the improved device.
A plurality of winding ‘units are usually mounti
ed upon a bed or frame 2 supported from the 30
?oor by legs 3 spaced along the machine. The
bed 2 carries brackets 4 which, in turn, support
bearings for the rotative elements of the winding
mechanism. The winding mechanism of the in
dividual unit herein illustrated comprises only 35
two principal elements, namely, the winding
mandrel or spindle 5 on which the yarn-receiver
or cop-tube C is rotatably supported and the
drive-roll l0 for rotating the yarn-receiver; and
in which is embodied means for traversing the’ 40
yarn back and forth axially of the package being
wound._ This particular form of traversing means
is fully shown and described in United States

for guiding a full bobbin B into place on the
supply-spindle 50 when it is desired to replenish
the supply. The chute 90 is inclined to the V81‘?
tical at a slightly greater degree than the spindle
Cl 50 to provide that after the bobbin B has slid
down the chute into position with its lower end
impaled on the end of the spindle, further sliding
movement of the bobbin will cause it to tilt up
wardly away from the chute as shown in Fig. 3.
The, improved supply holder having now been de
scribed in detail its method of operation will next
be explained.
Assuming that a full bobbin B is in place on
the spindle 5!! of the supply holder as shown in
15 Fig. 1 of the drawings, the strand y is drawn up
wardly through the slit 28 in the bracket 25,
threaded between the tension-disks 21, laid across
the traverse-roll I I] and its end attached to the
cop-tube C. The spindle-arm I5 is then lowered
20 to place the periphery of the cop-tube C in con
tact with the rotating drive-roll Ill. The roll [0
rotates the cop-tube to wind the yarn thereon as
the grooves in the roll traverse the strand back
and forth to deposit it in helical coils which
As the
winding proceeds and the yarn is taken off from
the bobbin B, eventually the end will run out and
the operation of the machine is automatically
arrested through the action of a suitable stop
30 motion, not herein shown.
The supply-spindle 50 is normally maintained
in substantially vertical position, as viewed in
Fig. 1, under its own weight and that of the bob
25 build up in layers to form the package.
bin B and the arm 41 with the arm resting
35 against the stop 16. Owing to the‘ inclination of
droponto a'traveling conveyorwhich removes
them from the machine.
‘It is to be particularly noted that although the
ejection. of the bobbin is above explained as being
caused by the action of the ejector-member 60,
the use of this element is .not essential. That is
to say, if the spindle 50 is swung upwardly rapid
ly, as provided for by the relatively short leverage
of the arm 64 to which the push-rod 65 is con
nected, the force of momentum will propel the
bobbin 01f from the end of the spindle. On the
other hand, the ejector-member 60 is provided
as a precautionary measure to insure a positive
ejection of the bobbin should the operator press
the push-rod 65 down too slowly.
Immediately the empty bobbin 1) has been
doffed'in the manner as above-explained the op
erator releases the push-button 10 and the weight
of the arm. 4‘! and the parts carried thereby re
turns the member 45 to ?rst position as illus 20v
trated in Fig. 4, with the arm 41 resting upon the
stop 16. During the return of the member 45
the counterweight 55 acts to control its movement
to prevent rebound as the arm 41 strikes the stop
16. With the arm 41 at rest the supply-spindle 25
50 will again be alined with the delivery point 23
of the tension-device l8 to insure proper delivery
of the yarn thereto. It will be understood that
during the return movement of the parts in the -
manner above explained the ejector-member 60
swings downwardly about its pivot 51 under the
action of gravity to position its pointed end
6| in the recess 54.
After the supply-spindle 50 has been returned‘
to ?rst position the operator places a fresh bob 35
bin B in the chute 9|] and releases it to permit it to
slide downwardly under the action of gravity
the stud 43 the spindle 50 is‘ inclined slightly with
respect to a vertical plane extending longitudi
nally of the machine, see Fig. 3, to provide that
the bobbin B will be axially alined with -the deliv
40 ery point 28 in the tension-device l8. It will be
observed by reference to Figs.'1 and 4 that with
a bobbin B in place on the spindle 50 the pointed
end 5| of the ejector-member 60 is positioned
impale it thereon. Due to the angular relation
ship of the chute 90 to the spindle 5|] the bobbin
in the recess 54 of the arm or extension 41 be
45 neath the head of the bobbin.
When it is observed that the yarn on the bob
B is canted upwardly away from the chute as it
slides onto the spindle in the manner indicated 45
by full lines in Fig. 3 to aline its axis with the
bin B' is almost exhausted the operator takes
his station at the front of the supply holder and
immediately the winding has been arrested the‘
50 push-button or ?nger-piece 10 is pressed down
wardly. The downward sliding movement of the
control-rod 65 rocks the member 45 on its pivot
63 to cause the arm 41 to rotate in a clockwise
55 direction as viewed in Figs. 1, 4 and 5. This
movement of the member 45 is aided by the
counterweight 55 so that only a slight pressure
is required on the push-button 10 to perform
the operation. As the arm 41 and spindle 50 are
60 swung upwardly the ejector-member 60 moves
with them until its toe 62 strikes the stop 80.
Further upward movement of the arm 41‘ causes
the ejector-member 60 to be rocked upwardly
about its pivot 51 with a quick action. The
65 movement of the ejector-member 60 is more
rapid than that of the spindle 50 and its toe 6|
ejects the empty bobbin 1) from the spindle 50
and propels it to one side of the supply holder
70 or in the direction indicated by the arrow in Fig.v
5. The swinging movement of the several parts
is limited by the engagement of the push-button
‘it against the projection 61 of the collar 68. A
box or like receptacle may be provided to receive
75 the ejected bobbins b or in other cases they may
while he holds the end of the yarn. As the bob-»
bin B slides downwardly in the chute in the man
ner indicated by the dash lines in Fig. 3 the 40
beveled end of the spindle 50 enters its bore to
delivery point 28 in the tension-device I8. The
fresh bobbin Bis then in position to supply yarn
to the winding unit and the end of its strand is
led upwardly through the tension~device I8 and 50
spliced to the trailing end on the package being

simple yet ei?cient device for the purpose. speci 55.
?ed. The improved supply holder is practically
entirely ‘automatic in operation, the operatorhav
ing only to press the button to e?ect the dof?ng
of the empty bobbin ‘and to then place a fresh
bobbin in the chute to cause it to be impaled on 60
the spindle in delivery position.
The bobbin-chute is placed in inclined posi
tion to enable the operator to quickly and,con—
veniently drop the bobbin thereinto. The holder
is placed in close‘ relationship with the tension 65
device and iii-elevated position to provide that
the end of the strand may be readily threaded
through the tension-device without requiring
stooping or reaching on the part of the operator.
The invention thus provides for a substantial
’saving in .the'time usually required‘ for dof?ngv
spent bobbins and supplying fresh ones in. their
place. ‘Moreover, less effort and energy is used
and the operator’s strength conserved for other
duties. The saving in time and effort is re
