1‘ Claim. (01. 242—43.7)
Referring to the drawing in detail, the inven
The‘ invention'relates to a bunch and ?lling
builder and more especially‘ to a‘ ?lling‘ and
bunch'builder mechanism for yarn winding ma
chines and spinning'frames that areadapted to
lay a preliminary winding or bunch on the bob
bins or yarn receivers prior to the laying of the
tion herein illustrated is applied to a ring spin
ning machine wherein the head end A is fastened
to-bolster rails Ill the top of which supports a
series of spindles provided with whirls H for 5‘
rotating 2. series of yarn bobbins l2 mounted on
main service winding thereon.
The primary object of the invention is the pro
vision of mechanism of this character, wherein
:10 the same is wholly automatic in its operation and
is adjustably carried by the frame of the ma
the spindles. A lifter rail l3 has a series of rings
!4 provided with the usual travelers and is sup
ported by a lifter rod I5, the lower end l6 of
chine so that the latter will run twenty-?ve to
tending from the bottom of the bolster rail Ill.
The lever I8 is counterbalanced by a weight l8’
whereby the upward traverse of thering rail is
thirty minutes longer according to the number
of yarn and effects the winding‘ of the thread
‘1:5 tighter on the bobbin, eliminating'all high end
which rests upon a roll I‘! mounted on the cross '10

Extending upward from the lever l8 vl5
pieces and places a great deal more yarn‘ on
is a segment arm 2| toMwhich is connected‘ a
the bottom of the bobbin and materially‘min
imizes waste.
Another object of the invention is the pro
20 vision of mechanism of this character, wherein
the yarn production is greatly increased both in
spinning and weaving and results in a better
grade of cloth.
A further object of the invention is the pro
of mechanism of this character, wherein
the ?lling runs from two to two and one-half
chain, in this instance including‘ two: separate
lengths 22v and 23, respectively, and‘ the'section
minutes longer in shuttle.
A still further object of the invention is the
provisionof mechanism of this character, which
30 is simple in construction, thoroughly reliable
and efficient in its operation, readily and easily
applied to the frame of a spinning machine,
wholly automatic in the working’ thereof and
inexpensive to manufacture and install.
With these and other objects in View, the in
vention consists in the features of construction,
combination and arrangement of parts as will be
hereinafter more fully described, illustrated in
the accompanying drawing, which discloses. the
"4'0 preferred embodiment of the invention, and
pointed out in the claim hereunto appended.

23 passes over the sheave pulley 24 and is then
connected to the ?lling winding lever 25 work 20
ing in conjunction with the builder lever‘ 26 of
usual construction pivoted on a stud 21 ?xed
to the head end A. While only a single lever l8
and lifter rod l5 are shown it is to be under
stood that any suitable number of these may be 25
used and may be connected, as usual, to move in
unison to cause the ring rail I3 to move up and
down under the control of the builder motion
as is common and well understood in ring spinning
machines. The winding lever 25 to which the 30
builder motion chain, that is the section 23
thereof, is attached derives its motion from the
rack 28 through action of a roll (not shown) fas
tened to the rack and coacting with the upper
surface of the winding lever 25. Motion is im- ‘35
parted to the rack bygthe worm connection of a
shaft 29. An intermittent motion‘ is impart-ed
to the shaft 2!} by the ratchet 30 ?xed thereon
acting in conjunction with the pawl 3i carried on
the arm 32 which is actuated by the rod 33 as the 40 -
builder lever 26 is raised and lowered.
parts and their assembly are-disclosed in Let
ters Patent No. 1,491,808 dated April 29, 1934.
To suit particular requirements as to speed
in the laying of the yarn onto the bobbin there 45
is arranged an inverted substantially T-shaped
bracket 34 upon the frame of the spinning ma
chine and this bracket at the base arm 35 has
provided therein an elongated slot 36 for accom
modating fasteners 37 mounted in the rail l0 5|)
thus it being seen that the said bracket 34 is
susceptible of adjustment longitudinally of this
rail 10 to alter or change the position of the
In the vertical stem portion of the bracket 34 55
is a perpendicular slot 381 for vertical adjust
able mounting therein of the attaching end 39
of a stud journal 4|] which is horizontally
disposed. Loosely journaled on the stud 40 is
a cam 4| having several stepped cam portions
42 and 43, respectively, and to the latter is
hinged at 44 the chain length 22 while to the
portion 42 is hinged at 45 the chain length 23
and under movement of these lengths in unison
10 with each other a slow motion of the rail at the
lower part of the spindles is‘ secured and then
gradually the motion is quickened at the upper
part of said spindles whereby a larger number
of yards of yarn may be wound on each spindle.
As indicated in Figures 1. and 2 of the draw
ing the cam 4| in its connection with the lengths
22 and 23 of the chain is such that when the
chain is moved the said cam will be rotated for
a part of a revolution. When the up and down
20 travel of the rail I3 is begun said travel is usu
ally at one and three-eighths inches but could be
any desired number of inches and this travel is
continually and gradually increased until the
bobbin is full and the travel of the rail has in
creased to one and three-fourths inches. This
increase of travel takes place after the bottom
of the bobbin is ?lled with yarn to the desired
diameter and the length of travel is caused by
the initial setting of the bracket 34 which set—
ting is ?xed by the fasteners 31.
The original
travel of the frame is one and three quarters
inches and when setting the travel for one and
three-eighths inches stroke such remains until
the cam 4| revolves to a point where its flat
.35 surface 42 disengages chain length 23 which then
rides onto the circular portion of said cam.
causes the stroke of the rail to increase to the
natural stroke of one and three-fourths inches.
The provision of the cam 4| causes the speed
of the rail |3 to increase as the cam 4| turns
over due to the chain length 23 riding on to
the surface 43 of the cam 4| at a greater dis—
tance from the center of rotation than the sur
face 42 (see Figure 3). It is to be noted that
45 when the mechanism ?rst starts the cam 4| is in
the position as shown in Figures 1 and 2 and
the chain length 23 is at the smallest diameter
of the cam 4| and as the latter rotates this chain
length 23 rides onto the larger diameter of said
50 cam. The ?rst part of the rotation of the cam
4| will cause the rail | 3 to move gradually up
wardly at substantially an even speed and when
the chain length 23 engages the larger diameter
of the cam 4| the speed will gradually increase
.55 in the movement of the rail I3 and in this man
ner of action the bobbins will be threaded tighter,
eliminating all high end pieces and a great deal
more yarn is placed on the bottoms of the bob
bins and also a larger amount of yarn is Wound
60 and this amount being arranged near the bases
of the spindles.
In order to e?ect the Winding of the yarn in
the form of a bunch at the lower part of the
bobbin the traverse of the ring rail is retarded
by means of a locking latch 46 abutting against
the builder lever 26. The latch is pivoted on
a stud 41 ?xed in a bracket 48 in stationary re
lation to the framing of the machine; the latch
being provided with an abutment member 49 ad
justably mounted on the lower part of the latch
and a knock-01f roll (not shown) operating in
conjunction with said lever to release the lock 10
ing latch 46.
In operation the operative after starting the
machine depresses the ring rail by means of foot
pressure applied to the end of the lever l8 thus
positioning the ring rail for the beginning of 15
the bottom traverse of the yarn. This action
also depresses the builder lever to its lowest
position acted thereon by the cam (not shown)
of the builder structure as disclosed in Patent
No. 1,491,808.
The operative then manually 20
swings the latch 46 so that the part 49 rests on
top of the lever 26 preventing it from moving
upwardly thus rendering the ring rail stationary
and causing the yarn to wind in a bunch; mean
while, the rotating motion of the cam gradually 25
brings the lug cam into contact with the knock
oif roll, the shape of the lug cam being such that
the locking action of the latch is removed from
the builder lever and in consequence the builder
lever resumes its upward and downward motion 30
without restriction thus permitting the main
winding of the yarn on the bobbin in the regular
manner. The latch after being pushed from
contact with the builder lever swings to such a
position as to be just out of the path of the 35
motion of the builder lever.
What is claimed is:
The combination with a ?exible element for
connection to a ring rail, a bunch builder, and
a ?exible builder element for actuation by the
bunch builder, of rotatable means interposed be
tween and attached to said elements for trans
mitting motion therebetween at variable speeds,
said means including a rotating member to which
the respective elements are connected, the mem
ber being formed with a peripheral recision to 45
provide cam surfaces at different distances from
the axis of said member and having the ?exible
elements attached to said surfaces respectively,
and a bracket adjustably attached to a frame
of a spinning machine and having a horizontally 50
disposed elongated slot therein, means passing
through the frame and slot for securing the
bracket in selected horizontally adjusted position
on the frame, said bracket also having an elon
gated slot disposed at substantially right angles 55
to the ?rst slot, a stud journal supporting said
rotating member and adapted to be mounted
adjustably in the second slot, and means for
securing said journal in selected position in said
second slot.
