SPINDLE ATTACHMENT FOR A SPUNNING
FRAME
Joseph P. McHugh, Scranton, Pa., assignor, by
mesne assignments, to Industrial Machine
Corporation, a corporation of Delaware
Application October 1, 1936, Serial No. 103,589
26 Claims.
This invention relates to a spindle attachment
for a spinning frame and is particularly Well
adapted for so-called multiple down ring spin
ning machines.
5
In its broader aspects, the invention compre
hends a spindle attachment embodying a spindle
whirl and brake mechanism so arranged that the
spindle whirl can be moved laterally away from
the driving belt and the brake concurrently ap
10 plied to the whirl.
‘
In its more speci?c aspect, the invention com
prehends a spindle attachment in which the
spindle and whirl move laterally with respect to
the belt in a plane perpendicular to the line of
15 travel of the belt, and the lateral movement of
the spindle functions to apply the brake in such
manner that the further the spindle is moved,
the greater will be the application of the brake.
Various types of swing spindle attachments for
20 spinning frames have heretofore been devised,
and in such prior art spindles it is usual to pro
vide some braking), means for the spindle whirl.
The brakes, however, often become worn, and
2
there is lack of uniformity of application of the
brake to the whirl. Through the medium of the
present invention, the di?iculties encountered in
the priorart practices are obviated, and a struc
ture is provided which insures the positive appli
cation of the brake throughout the life of the
30
device.
‘
Other and more detailed objects will become
apparent as the description of the invention
proceeds, which description will be given in con
nection with the accompanying drawing, where
35 in:
Figure 1 is a detailed plan View of the swing
spindle attachment with the spindle removed and
parts broken away for clearness;
Figure 2 is a side elevational view taken from
40 the front of the spindle attachment;
Figure 3 is an end elevation taken from the
left-hand side of Figure 2; and
Figure 4 is a detailed fragmentary view with
parts shown in section.
Referring to Figure 1, the spindle rail is formed
45
in two parallel tubular elements I and 2 which
extend longitudinally of the spinning frame in a
conventional manner. The spindle attachment is
adapted to be ?rmly clamped in ?xed relation to
50 the members i and 2 through the medium of
the clamping bolt 3 (Figure 2) and the clamping
member 4 adapted to be positioned below the par
allel tubular members I and. 2. The upper end of
the bolt 3 extends through the ?xedly mounted
55 base member 5 as shown at 6. The base member
(01. 118-8)
:
5 supports all of the operative elements of the
spindle and brake. The base 5 is provided at one
side with the upwardly projecting ?ange 1 car
rying at the forward side of the base 5 the arm 8
which is provided with a spring seat 9 having the
adjustable screw I0 for controlling the‘degree of
tension placed upon the spring II which func
tions in a manner hereinafter described.
The opposite end of the base member 5 is pro
vided with a ?ange I2. The ?ange I2 carries
a bearing pin I3 adapted to pivo-tally support the
lower end I4 of a stop motion rod I5. This stop
motion rod is designed to have pivotal motion
about the pivot bearing I3 in a manner compa
rable to that of the stop motion rod shown and
described in my Patent No. 2,044,621, issued June
16, 1936, to which reference may be made for the
detailed character of the stop motion mechanism
associated with the rod I5.
Pivotally supported between the flanges ‘I and
I2 of the base member 5 is the U-shaped yoke I6.
This U-shaped yoke I6 is provided at the free
end of each of the legs thereof with an integral
upstanding bracket member IT. This yoke I6 is
pivotally supported on the base member 5 through
the medium of the adjustable bearing member I8
(see Figure 2) having the conical bearing surface
I9 ?tting into a complementary recess 20 in the
yoke and by the similar bearing provided by the
screw I3 at the opposite end of the base 5 shown
in detail in Figure 4, wherein it will be observed
that the screw I3 is likewise provided with a
conical bearing end 2| ?tting into the comple
mentary recess 22 of the yoke member I6. The
screw I3 additionally carries the adjusting nuts
23 for accommodating the pivotal bearing I4 of 3
the stop motion rod I5, regardless of the position
of adjustment of the bearing screw I3, and for
locking the bearing screw I3 in any particular
position of adjustment in the threaded opening
24 of the flange I2. A similar locking nut 25 is 40
provided for locking the bearing screw I8 in any
particular position of adjustment with respect to
the theaded opening 26 in the ?ange ‘I.
It will be observed from the foregoing descrip
tion that the yoke member I 6 is adapted to have 5
a limited rocking movement about a horizontal
axis formed by the bearing screws I3 and I8.
The right-hand bracket arm H on the yoke I6, as
shown» in Figure 1, is provided with a seat 26' for
one end of the spring II. The spring I I thus
functions to press the upper‘ends of the bracket
0
arms I‘! away from the arm 8 carried by the base
member 5 and toward the spindle driving belt 21
of the frame.

The yoke l6 carries a spindle base 28.
This
spindle base 28 is supported by the complementary
bearing screws 29, one of which extends through
the top of each of the bracket members H. The
bearing screws 29 are adapted to be locked in any
position of adjustment through the medium of
the locking nuts 31!. It is thus apparent that
the spindle supporting base 28 is adapted to have
limited rocking movement with respect to the
10 yoke l 6, which in turn is adapted to have limited
rocking movement with respect to the base 5.
The spindle base 28 is provided with the opening
3| in which the spindle 32 having the conven
tional whirl 33 is adapted to be clamped through
15 the

nutpro
jecting arm 36 adapted to extend into the path
of movement of the stop motion rod l5 when the
latter is released through the breaking of a thread
and swings outwardly about its pivot M.
It will be apparent that when the stop motion
rod l5 contacts the arm 36 of the spindle base
28, the yoke it will swing upwardly with respect
to the base 5, and the spindle base 28 carrying the
25 spindle 32 will be caused to move laterally away
from the belt 2'? to free the whirl 33 therefrom.
When the stop motion rod I5 is restored to oper
ative position, the spring H functions to return
the yoke I6 to normal position with the whirl 33
30 in driving engagement with the belt 21.
Coming now to a speci?c description of the
means for controlling the movement of the spin
die and for applying the brake to the whirl, it
will be observed that the spindle base 28 is addi
tionally provided with a bearing lug 37 (see Fig
ure 3) and that the ?ange 52 of the base 5 carries
a further bearing screw 38. A bearing bolt 39
extends through the bearing lug 31, and a link
40 has its respective ends pivotally mounted on
40 the bearing screw 38 and bearing bolt 39. It
will be observed by reference to Figure 3 that the
?ange 12 of the base member 5, a bracket member
ll of the yoke Hi, the spindle supporting base
28, and the link 40 together form a parallelogram,
45 the four corners of which are pivotally connected.
The base member 5 and the ?ange 52 are, however,
?xedly secured to the spindle supporting rail and,
therefore, the spindle supporting base 28 is
adapted to swing toward and away from the belt
but is always maintained in a horizontal plane
with the spindle 32 carried thereby always in _a
vertical position.
The spindle base 28 further carries in ?xed
relation thereto the upstanding arm 4!, which
55 arm is adapted to partake of the same movement
as the spindle base member 28. The arm 4i
carries at its upper end a bearing bolt 42. A
brake member indicated generally at 43 is pivot
ally mounted on the bearing bolt 42. The brake
60 member 43 is generally U-shaped with one leg
44 of the U extending clear down to the bearing
38 and being bifurcated to accommodate the
bearing 38 as shown at 45 in Figure 3.
The other
leg 46 of the U-shaped brake 43 extends down
65 wardly to a short distance below the pivotal
mounting 42 and carries at its lower end the fric
tional brake contact member 41.
The action of the brake is as follows: When
the stop motion rod 15 is released and moves the
70 spindle base 28 laterally with respect to the base
member 5, the bearing 42 is likewise moved lat~
erally and downwardly with respect to the base
member 5. This movement of the bearing 42
causes the brake member 43 to be moved about
75 the bearing 42, and. because of its relationship to
the bearing 38, the brake shoe 4? is adapted to be
forced into contact with the whirl 33. It is at
once apparent that the greater the movement of
the base 28, the greater will be the force applied
to the brake shoe Ill and thereby to the whirl 33
of the spindle.
Briefly summarizing, the operation of the device
is as follows: When a thread breaks, the stop
motion rod l5 swings about its pivot l4 and ap
plies force through the arm 36 to the spindle base 10
28. This swings the upper ends of the bracket
arms H of the yoke 56 on the bearing screws 63
and H3.
The spindle base 28 in turn rocks slightly
on the bearing screws 2%, but this rocking move
ment is controlled by the link 46 interconnecting
the bearing 39 carried by the spindle base 23 and
the bearing 38 carried by the bracket base 5, so
that the spindle base 28 moves laterally and
downwardly with respect to the base 5 but is al
ways maintained in a horizontal position. This 20
movement of the spindle base 28 likewise effects
movement of the brake bearing 42 and applies
the brake in the manner above speci?cally set
forth.
From the foregoing detailed description, it will 25
be apparent that the applicant has provided a
novel spindle attachment for a spinning frame,
through the medium of which the spindle base
is swung away from the belt on horizontal rather
than vertical pivots, and a structure whereby the 30
brake is positively applied to the spindle whirl
through mechanical motion that counteracts the
movement of the spindle. It will be additionally
observed that the respective bearings are adjust
able, permitting slight relative movement be-=
tween the respective parts of the spindle at
tachment and furthermore making it possible to
immediately compensate for wear at any time.
