Improvements in Machines for Winding Cord or like material.
I, JOHN EDWARDS BARBOUR, of 321, Broadway, Paterson, Passaic County,
New Jersey, United States of America, Linen Thread Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
―:
My invention relates to devices for winding cord, and especially to those devices
in which the cord is drawn from reels, or any other form of cord supply, and
wound by machinery upon balls or cops, and more especially to that special device
in which the cord passes through a reciprocating guide, in the process of winding.
The objects of my invention are to provide:
First: A means for saving time in winding.
Second Means for saving labor.
Third: Means for preventing injury to the cord.
I attain these ends by the device illustrated in the accompanying drawings
and hereafter fully described,-like letters of reference referring to similar parts
throughout the various views and the description. Heretofore in devices of this
class, when the free withdrawal of the cord from the reels became prevented,
owing to various causes, among which were some obstacle tending to prevent
the rotation of the reel itself--or more often the formation of a knot or tangle
in the cord the cord remaining in the guide would saw back and forth with
the reciprocations of the latter, constantly chafing on portions of the machine
and the ball or cop itself, and thus resulting in wear, roughening, weakening
and sometimes rupture of the cord, and always, if the motion long continued,
in its injury.
As it is customary to build these machines containing a large number of
separate winding elements all driven by the primary power, it is evident that
it was impracticable to stop the whole machine when one element became ob-
structed, therefore it frequently occurred that one or more elements might be
obstructed for a less or greater period of time before the obstruction could be
removed,, and during such time the motion of the reciprocating devices con-
tinuing, resulted in the aforesaid injury.
By my invention, however, each separate element is provided with an auto-
matic release or stop motion, by which, as is hereafter more particularly described,
the cord is instantly removed from the reciprocating guide, upon the stopping or
hindrance of the feed from the supply, and is as immediately thrown in again
upon the resumption of the feed, after the removal of the interfering cause.
Fig. 1 represents a partly sectional end view of my improvement, as applied
to an organized machine for winding balls or cops, in which a number of elements
are combined and driven by the usual means.
Fig. 2 is a front elevation of a portion of the organized machine showing two
elements, with my improvement applied, the one on the left normally operating,
while the one on the right shows my device operating to stop the motion, or
sawing, of the cord.

page_text: 1 is the reel of cord;
2 a strand of the cord as it leaves the reel before passing over the safety device;
2 illustrates such strand when the reel is reversed and the cord is unwinding
from the rear, the operation of my improvement being the same in either
instance;
2b illustrates such strand when drawn down from its normally tangential posi-
tion with respect to the reel by the knot or tangle 12;
3 represents the apron or main body of the safety device, made curved so as
to present a smooth surface without an obstructing edge, although I do not
limit myself to such shape;
3 are ribs constructed thereon to keep the cord or strand within proper limits;
3 is an axis, about which the safety device is free to turn, being normally
maintained in a substantially horizontal position by means of the weight or
counter-balance, 4;
4 is this counter-balance, of such weight as to maintain the flat portion of the
apron 3, substantially horizontal, save when unusual or abnormal strain is
imposed on the strand 2-2, when, in such case, the safety device is revolved
partially about 3b in spite of the counter-weight, for the purpose hereafter ex-
Ilained;
5 is the strand guide which reciprocates in front of, and close to the cop or
ball 7 for the purpose of laying the strand properly upon the cop, it is usually
formed with smooth edges so that the cord or strand may be easily and without
injury placed in or out of it, but is of such form and dimensions as to normally
retain the strand; as this is well known in the arts, I do not claim it, and need
not further describe it;
6 represents the strand lifted out of the guide 5 by the operation of the safety
device, as shown in the dotted lines;
represents the cop or ball being wound, shown in dotted lines in Fig. 3;
8 represents a lever frame bearing the cop or ball, shown in dotted lines in
Fig. 3, to avoid confusion in the drawings; this frame is free to partially revolve
about the axis 8" and normally permits the cop 7 to rest on the driving rolls 10
which rotate the cop by the resulting surface friction.
These rolls are supported in the arm 9, forming a part of the frame 11 of the
machine.
The operation of the device is as follows:
When the reel bearing the skein of cord 1 is placed in position on the machine,
or when another means of cord supply is used, when the strand is to be connected,
the strand is led as at 2 or 2 over the apron 3 of the safety or stop motion device
and between the ribs 3" thereon, then through the guide 5 and on to the cop
tube held in the lever frame 8, which bears, as has been said, on the driving
rollers 10.
So long as the motion and feed continues constant, the safety device is inopera-
tive, and the strand is retained in the guide 5, performing its usual functions.
If, however, a knot forms in the skein, or the reel is caught, or undue tension
is otherwise applied to the strand 2, this tension pulls down the apron 3 revolv-
ing the safety device about the axis 3b, the counter-weight 4 being adjusted so
as to allow this revolution upon the imposition of abnormal tension or strain, the
effect of such revolution is to raise the weighted end over which the strand passes
normally into the guide, and such raising at once lifts the strand out of the
reciprocating guide 5, allowing the guide to continue its reciprocations under
the strand but not in contact therewith, as shown at 6, Figures 1, 2 and 3.
The strain is also sufficient to cause the cop to stop-slipping upon its driving
roller 10-but not in any way injuring the strand.
As soon as the difficulty has been removed, and the tension become normal,
the counterbalance brings the apron back into its usual position, and permits

page_text: the strand to drop down so as to engage with the guide, into the eye or notch
of which it drops, and thereupon the winding is resumed.
While I am aware that similar guides, reels, driving mechanism, and cops,
are well known in the art, and therefore do not claim them broadly, I still do
not wish to be limited to machines for winding cops alone, or balls alone, or any
other peculiar form of product, as it is evident my invention is applicable to
any form of device for winding or putting up cord or similar material. Nor
do I confine my invention to machines or means for taking the cord from any
special or single form of reel, skein, ball, cop, or other cord supply, as it is evident
that my invention is applicable in connection with any kind of cord supply,
and when the word "reel" or skein," or other specific word is used herein,
it is to be understood as simply indicating a general idea of a cord supply.
"
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed; I declare that what I
claim is:
1. The herein described improvements in cord or like winding machinery,
namely, effecting the removal or rejection of the strand from its guide by the
application of excess of tension to the strand; for the purposes set forth.
2. In a cord winding device having a thread guide, a counter-balanced tilting
apron or device over which the cord passes, provided with means for limiting the
lateral movement of the cord; operating substantially as set forth.
3. In a winding device, a counter-balance tilting apron or device over which
the cord passes, combined with a strand guide, adapted to automatically engage
or disengage the strand.
4. The combination of winding mechanism and means operated by the resist-
ance of the cord, to engage or disengage the cord with the winding mechanism.
5. In a winding machine, a strand guide open on a line perpendicular to the
object to which the cord is being transferred, and a counterbalanced tilting apron
provided with guiding ribs, and adapted to automatically engage or disengage
the strand with the guide; substantially as set forth.
6. In a cord winding machine, the combination of a counterbalanced tilting
apron, with cord winding mechanism, the tilting apron being adapted to move
the cord out of or into engagement with the winding mechanism.
7. In a winding mechanism, means for automatically moving the cord into
or out of engagement with the same; for the purposes specified.
8. In a cord winding machine, a tilting apron, and strand guide, arranged,
constructed, and adapted to operate substantially as set forth with reference to
the drawings.
9. The winding machine having the parts arranged, constructed, and adapted
to operate, as set forth with reference to and shewn in the drawings.
