RECLAIMING ATTACHMENT FOR BRAIDER
BOBBINS
John Winstanley, Fall River, Mass, assignor to
Winstanley Bros., Fall River, Mass.
Application January 31, 1938, Serial No. 187,955
4 Claims.
This invention relates to an attachment for
wooden braider bobbins whereby bobbins having
worn ratchets can be used e?iciently with carriers
of the ordinary latch or pawl type.
It is well known to those skilled in the art that
the ratchet teeth of wooden braider bobbins
quickly become worn and rounded with the re
sult that frequent stoppage occurs.
An object of the present invention is to equip
10 the bottom or ratchet portion of a wooden braider
bobbin with a toothed latch engaging member of
metal or other suitable wear-resisting material,
the teeth thereof being positioned to engage the
latch instead of the wooden teeth of the bobbin
15 ratchet whereby it is possible to use worn braider
bobbins at maximum braider speed without caus
ing breakage of yarn or stoppage such as cause
the bobbins to throw slack.
V
A still further object is to provide a braider
bobbin attachment which, because of the elimi
nation of all possibility of locking due to wear,
permits a free, easy and regular tension on the
yarn as it is unwound and enables the braiders
to run at a speed which is well above what is
25 considered reasonable under ordinary practice.
With the foregoing and other objects in view
which will appear as the description proceeds,
the invention consists of certain novel details of
construction and combinations of parts herein
30 after more fully described and pointed out in
the claims, it being understood that changes may
be made in the construction and arrangement
of parts Without departing from the spirit of the
invention as claimed.

In the accompanying drawing the preferred
form of the invention has been shown.
In said drawing—
Figure 1 is a side elevation of a braiding ma
chine carrier showing the present improvements
40 applied to the worn ratchet of the bobbin.
Figure 2 is an elevation of the structure shown
in Figure l as viewed from the left of said ?gure.
Figure 3 is a plan view with the bottom re
moved.

‘
Figure 4 is a central vertical section through
the reclaiming attachment constituting the pres
ent invention.
Referring to the ?gures by characters of refer
ence A constitutes the base portion of a carrier
50 provided with a spindle B adapted to engage and
support a package which can be in the form of
a bobbin C formed of wood and provided with
the usual ratchet teeth D at the bottom thereof.
In the structure illustrated the carrier includes a
55 pawl E having a tooth F adapted to move into
(01. 96-45)
and out of the spaces between the ratchet teeth.
This pawl is connected to a wire G having a loop
H which is slidable on a standard I projecting
upwardly from the base A. A weight J is slid
able on the standard and, under normal working
conditions, is supported by the leading thread K
extending from the package and which thread
is extended through the standard and upwardly
therefrom. Thus the weight J normally is held
elevated against loop H so as to support the pawl
E out of normal position with the tooth F dis
engaged from the ratchet. The pawl is thus
maintained under normal working conditions but,
should the thread become slack from any cause,
the weight J will descend by gravity as shown in 15
Figure 1, thereby releasing loop H and allowing
the tooth of the pawl to move upwardly into po
sition between two of the teeth of the ratchet
on the bobbin.
The structure thus far described constitutes
no part of the present invention but is in general
use. While it results in ef?cient operation as long
as the teeth of the ratchet on the braider bobbin
are not worn, it has been found that as these
teeth wear due to contact with the pawl, the e?i
ciency of the braider bobbin is lessened until
ultimately it becomes necessary to discard the
bobbin due to the resultant frequent stoppage.
As before stated the present invention is de
signed to permit e?icient use of the worn braider 30
bobbin and in the drawing the attachment con
stituting this invention has been shown combined
with the worn ratchet teeth of a bobbin. This
attachment is in the form of a central disk I
having an opening 2 for the reception of the
spindle B and from the periphery of the bobbin
radiate wear-resisting teeth or liners 3 the side
faces of which preferably diverge outwardly as
shown particularly in Figure 3 while the top faces
are slightly pitched as shown at 4 in Figure 4.
These teeth are regularly spaced and are equal
in number to the teeth of the ratchet. They are
so located and shaped that, when the attache
ment is assembled with the ratchet end of a
braider bobbin, the wear teeth or liners will ?t
within the respective recesses between the teeth
D of the ratchet thereby presenting wear faces
which will be abutted by the pawl as shown par
ticularly in Figures 2 and 3. As these liners are
applied to the worn faces of the ratchet teeth the 50
said faces are prevented from being engaged by
the pawl and, consequently, the ratchet will, in
effect, be a wooden one the teeth of which are
faced with metal or other wear-resisting mate
rial. However as these facings form integral 55

parts of the ring I and are readily renewable and
can be quickly applied to a Worn braider bobbin,
the attachments in their complete form are de
signed to be sold to the trade as such for quick
installation.
Consequently a considerable sav
ing is effected because of the fact that bobbins
which heretofore have been discarded as un?t
for use, can continue in service inde?nitely. Fur
thermore, through the use of the reclaiming at
10 tachment it has been found, in practice, that it
is possible to run the braiders at a speed well
above that considered reasonable for braiding
machines utilizing wooden bobbins without the
attachment.
What is claimed is:
15
1. As an article of manufacture, a reclaimer
for wooden braider bobbins including an aper
tured disk and regularly spaced radial liners pro
portioned for engagement with the working faces
20 of ratchet teeth on a bobbin.
2. As an article of manufacture a reclaiming
attachment for wooden braider bobbins having
ratchet teeth, comprising spaced lining means
proportioned for engagement with the working
faces of the respective teeth of the ratchet and
an integral connection between said means.
3. The combination with a braiding machine
carrier including a spindle, a pawl, and pawl-ac
tuating means, and a braider bobbin on the spin
dle and having a ratchet, of means on the spin
dle and interposed between the ratchet teeth and
the pawl for transmitting thrust from said teeth
to the pawl.
10
4. The combination with a braiding machine
carrier including a spindle, a pawl, and pawl
actuating means, and a braider bobbin on the
spindle and having a ratchet, of means on the
spindle and interposed between the ratchet teeth 15
and the pawl for transmitting thrust from said
teeth to the pawl, said means including a spindle
receiving portion and radial members integral
with said portion and positioned and propor
tioned for engagement with the working faces of 20
the respective teeth of the ratchet.
