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
drawing.

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
movement.
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

It will be understood that there are a plurality of 50

The members 22 may preferably be formed of
