An object of .the present invention is to pro
vide an improved spool supporting bracket for
winding machines which may be cheaply made
10 and which will provide an oilless bearing surface
With the above and other objects in View the
invention may include the features of construc
tion and operation set forth in the following
specification and illustrated in the accompanying
for the spool spindle ends during the winding
Y In the accompanying «drawing annexed hereto
Another object of the invention is to provide
_ a detachable end piece for a spool supporting
15 bracket which when worn or damaged may be
removed and another end piece substituted there
fore at a minimum expense.

Another object of the invention is to provide
bearings for the extended spindle ends of the
bobbins that will be non-metallic and thus en
tirely rust proof so that no rust will be formed
that might be transferred to and damage the
yarn being woun-d upon the bobbins.
And finally it is an object of the invention to
provide a rigid moulded fibre member for the
end piece of a spool supporting bracket having
flanges thereon extending laterally and forming
with the end face of the bracket substantially
vertically disposed recesses or slots within which
the spindle ends of the spools may ride upward
as the spools flll with the yarn and be retained
during the winding operation against lateral
A feature of importance of the invention and
35 which enables the above objects to be accom
plished is that the spool supporting ends of the
brackets of a winding or twisting machine are
surfaced so that in their operative positions the
end faces of the brackets will be in a substan
40 tially vertical plane parallel to the longitudinal
members of the winding machine. This surface
preferably has a central groove or shallow recess
which serves as a supporting surface for a de
tachable member having the central web of the
45 member entering the groove or recess.
This de
tachable member is preferably of vmoulded fibre
requiring no lubrication or may be of any well
known oil-less metal bearing. This member has
oppositely disposed laterally extending flanges
50 which are spaced from the end face of the bracket
and which form with the end face the necessary
guideway or space for the spindle ends of the
spools being wound. As the win-ding pressure is
always against the inner surface of the flange
55 during the winding operation and away from
and forming a partv of this specification, the in
vention is shown embodied in a spool winding
machine for textile yarn of standard formV but it 15
will be understood that the invention can be
otherwise embodied and that the drawing is not
to be construed as defining or limiting the scope
of the invention, the claims appended to this
specification being relied upon for that purpose. 20
In the drawing Fig. 1 is a plan View of a por`
tion of a spool winding machine having the im
proved spool supporting bracket and guide shown
in position thereon; and
Fig. 2 is a side elevation of the parts shown in 25
Fig. 1 partly in section.
Briefly, and in its preferred aspect, the inven
tion ‘may include the following principal parts;
first a spool supporting bracket of the general
form now used in standard winding machines, 30
Vthe spool supporting end or ends only being
modified; and second, a detachable member se
cured to the end face of the bracket, this member
preferably being moulded and of such material
as will not require lubrication to be supplied 35
.thereto and formingrwith the end face of the
bracket a substantially vertical slot or recess on
each side of the bracket within which the spindle
ends of spools being Wound may extend and be
retained while movable upward as the spool be 40
comes iìlled withryarn. The recess formed by
each flange is suñiciently deep to accommodate
the spindle en-d of a spool and with .the opposite
recess of an adjacent bracket will prevent end
wise movement of a spool.
Referring more in detail to the figures of the
drawing there is provided a spool supporting
bracket lil attached as shown in the usual manner
to the frame members. it of a winding machine.
It will be understood that there are a plurality of 50
these brackets lil disposed parallel to each other
and uniformly spaced longitudinally of the ma~
chine. The winding machine may be of any
standard form for winding, twisting, doubling o1'
spinning textile yarns and each bracket Il] may 55
be similar to the others. For that reason but
one pair of brackets Iû for supporting a spool I2
is shown.
sitions are also suitable.
Below the brackets I0 are traverse rod sup
porting brackets I3 having rollers I4 on which a
traverse bar or rod I5 may reciprocate. Sup
ported below the brackets I@ and I3 is a driving
bers 22 are durable and rigid enough to be secured
to the brackets by several screws 25 extending CII
In any case the mem
shaft I6 having friction wheels I’I adapted to
engage and rotate the individual spools I2. In
through their central webs and being threaded
into the forward end faces 2D of the brackets I0.
I claim:
1. A spool bracket for winding machines hav
the form of machine shown in the drawing the
friction wheels |'I directly contact the yarn being
ing member detachably secured thereto and form
wound which is supplied to the spools I2 from
ing with the end face of said bracket oppositely
any position (not shown) and passes over a guide
I8 on the traverse bar I5 prior to being wound
on the spools.
Each of the spools I2 is provided with central
disposed vertically inclined recesses within which
the extended ends of adjacent spool spindles may
spindles having ends I9 extending from each end
flange of the spool. It is by means of these
extensions I9 that the spools I2 are held properly
will not require lubrication to be periodically sup
plied. Metallic, or metallic and graphitic compo
positioned during the winding operation,
The end face 20 of each bracket I0 is finished
by being milled or planed so that in position this
surface is vertical and substantially parallel to
the longitudinal axis of the machine. Also formed
[3 Cn on this end face is a shallow and narrow slot or
recess 2| extending the full vertical length of the
surface and disposed centrally thereof. Secured
to this end face is a T shaped member 22 prefer
ably having a central web portion entering the
30 groove or recess 2|. Laterally extending flanges
23 of the member 22 extend parallel to the end
faces 20 on opposite sides of the groove or recess
2|. There are thus formed on oppositer sides of
the brackets I9 substantially vertical guideways
24 within which the spindle extensions I9 may
enter and guide and support the spools I2. With
the spool I2 disposed as shown in Fig. 2 and with
the driving wheel I'I rotating upon the axis and in
the direction as shown the pressure. of the exten
40 sion I9 during the winding operation will be
against the member 22. All wear due to this pres
sure will occur on the member 22 rather than upon
the end faces 20 of the brackets I0. By replacing
the members 22 when worn the spools I2 will be
properly guided at all times without replacement
of the complete brackets I0.
The members 22 may preferably be formed of
integrally moulded material not requiring subse
quent machine operations.
Textile ñbres or fab
50 rics moulded in a phenolic condensate such as
Bakelite or other well-known composition may be
used. Preferably a composition is chosen which
ing at its spool engaging end a moulded ñbre bear
be disposed during the winding operation.
2. A spool bracket for winding machines having
at its spool engaging end a moulded fibre bearing
member detachably secured thereto and forming
with the end face of said bracket a vertically in
clined recess within which the extended end of a
spool spindle may be disposed during the winding
3. A spool bracket for winding machines having
at its spool engaging end a flat surface, a fibre
bearing member attached to said end of the 25
bracket having a laterally extending flange there
on, the flange forming with said end face a sub
stantially vertical recess within which the ex
tended end of a spool spindle may be disposed dur
ing the winding operation.
4. A spool bracket for winding machines having
at its spool engaging end a detachably secured
bearing member, said member having laterally ex
tending iianges thereon spaced a short distance
from the end face of said bracket whereby the 35
extended spindle end of a spool may be disposed
Within the recess between said bracket end face
and a flange, a central web portion on said mem
ber, and securing means for said member passing
through said web portion.
5. A spool bracket for winding machines having
at its spool engaging end a detachably secured
fibre bearing member, said member having a cen
tral portion engaging and secured to the bracket
within a slot provided in the end face thereof , and 45
flanges formed on said bearing member forming
substantially vertical uniformly wide recesses on
opposite sides of the bracket, whereby the extend
ed ends of spool spindles may engage therein dur
ing the winding operation.
