8- Claims. (Cl. 117-265‘)
This invention relates to‘c'ertain new ‘and useful
improvements in the ?iers employed in connec
tion with spinning machines and the like. "
It has for its chief object to provide a ?ier
5 structure having simple and effective means for
preventing the ?ier overrunning or continuing to
revolve after the bobbin has come to rest, thereby
to prevent kinking or looping of the twisted yarn.
Another object of the invention is to provide
10 a braking device for ?iers which is simple and
inexpensive in construction, which is designed‘
for ready assemblage to the ?ier structure; and
which is of minimum weight.
Other features of the invention reside in the
1r, construction and arrangement of parts herein
after described and particularly pointed out in
the appended claims.
In the accompanying drawing:-—
Figure 1 is a fragmentary front view of a por
tion of a spinning machine showing the improved
?ier applied thereto. Figure 2 is an enlarged top
plan of the ?ier and associated bobbin. Figure
3 is a bottom plan view of the ?ier. Figure 4
is an enlarged fragmentary vertical section taken
in the plane of line 4—4, Figure 2. Figure 5 is
an enlarged horizontal section of the hub and
brake structure taken substantially in the plane
of line 5—5, Figure 4. Figure 6 is a side eleva
tion of the hub or sleeve of the ?ier body.
Similar characters of reference indicate corre
sponding parts throughout the several views.
The invention is applicable to spinning ma
chines of any suitable and well known construc
tion, Ill indicating the bobbin-spindle and H the
35 take-off bobbin mounted thereon. The thread or
yarn from the bobbin extends upwardly through
the eyes of the ?ier wires l2, 13 mounted on a
holder or ?ier-body applied to the bobbin-spin
dle and thence upwardly through a guide or cen
tering eye M to a take-up spool (not shown).
The bobbin shown is of the type used with ?iers
of the eccentric type and has a recess IS in its
top containing an inverted cup-like member it
having an opening I‘! therein arranged concen
45 tric to the axis of the bobbin-spindle.
The ?ier-body preferably consists of an attach
ing sleeve, hub or barrel [8 made of ?ber or like
material and adapted to be ?tted over the bob
bin-spindle. At its lower end this sleeve has an
eccentrically-shaped ?ange l9 adapted to be
passed through the cup-opening l1 during the
application and removal of the ?ier to and from
the spindle.
Spaced above the eccentric ?ange
is a circular ?ange 20 and ?tted about a neck 2|
55 rising from this ?ange and hearing or shouldered
‘I .
against the‘ top side of the latter. is a base‘ plate
or spider 22 to which the ?ier wires I2, I3 are
connected. The base plate has a depending
tongue 23 adjacent its sleeve engaging opening
which engages a companion notch 24 in the ‘
sleeve-?ange 20 to lock the parts against relative
Extending about the sleeve-engaging opening
of the base plate 22 is an outwardly-facing annu
lar bead or ?ange‘ 25" spaced from the topside 10
of said plate to provide an annular groove 26' in
which is disposed a locking ring 21. for operative
engagement with the inner ends of the ?ier wires
for securely retaining them in the customary. plate
loops 28.
At its upper end the sleeve l8 terminates in an
enlarged circular head or ?ange 29‘ and seated
between the bottom‘ face of this‘vhea'd andrthe
base plate ?ange 25‘ is a split rin‘g'30" which'serves
to effectually anchor the base plate to the sleeve.
It will be noted that the upper ?ange 29 is of less
diameter than that of the.lower ?ange 25 and
slightly smaller than that of the base-plate open
ing, so that the base plate can be readily ?tte
to the sleeve I8.
The improved brake for preventing overrun
ning of the ?ier after the bobbin has come to rest
is borne by the sleeve or hub N3 of the ?ier and
preferably consists of a brake element 3| substan
tially in the form of a pin which is guided in an 30
opening 32 formed radially in such sleeve through
the bore thereof, and which is adapted for fric
tional or braking contact with the bobbin-spin
dle II]. This brake element is, by preference, dis
posed between the sleeve-?anges 20 and 29 and
seated in an annular groove 33 between such
?anges is a retaining spring 34 which extends
over and bears against the head 35 of the brake
element and constantly urges the latter into yield
able frictional contact with the bobbin spindle
and resists outward displacement of such brake
element from the sleeve. This retaining spring is
made of spring wire and is substantially circular
in shape, one end thereof terminating in an in
wardly or radially-bent arm 36 which abuts edge
wise against the bottom of the groove 33 to resist
its turning relatively to the sleeve.
By this construction, the braking element con
stitutes an inherent part of the hub structure of
the ?ier, and it does not disturb the balance fac
tor of the ?ier nor add materially to its weight.
Furthermore, the braking elements may be readily
assembled and in the structural assembly of the
other parts of the .?ier the brake element 3| and
its spring 34 are permitted the necessary freedom 55
