Improvements in Machines for Doubling and Winding Yarns and
Threads.
I, JOSEPH ROBERT LEESON, of 226 Devonshire Street, Boston, Suffolk County,
State of Massachusetts, United States of America, Manufacturer, do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:
-
My invention relates to certain improvements in winding machines for winding
threads to form cops, and has for its object to secure proper varying tension or
drag upon the thread as is requisite at different times in the winding, and to
arrest the movement of the winding machine in case of the breaking of any one
of the threads; and to these ends, I combine with a winding machine of any suit-
able construction the parts hereinafter described and illustrated in the accom-
panying drawing, in which:-

stopping device.
The features of my improved apparatus are adapted to be used in connection
with a single winding machine or with machines arranged in series or gangs.
As shown in Fig. 1, there are two winding machines A, upon a single table or
frame X, but I have shown my multiple devices in connection with but one of
them.
The winding machines may be of any of the usual characters. As shown, each
machine has a cam shaft 2, and a cop shaft 7, which in the construction shown is
driven uniformly during the winding, and upon which the cop Z, is wound, the
thread passing through the eye of a reciprocating guide 1, upon a swinging
frame B, which swings concentrically with the cam shaft 2, and is counterbalanced
CD 017

page_text: by a weight 8, so that the frame and the guide may swing back as the cop increases
in diameter. The machine is provided with any suitable kind of a stopping device.
As shown, there is a stop lever 5, having a lug engaging with a lug upon a detent
lever C, pivotally attached to the machine, and provided with a laterally pro-
jecting arm 4, with which is connected a rod D. When the parts are in the
position shown in Fig. 3, the machine will operate to wind the cop, but when the
rod is drawn downward, swinging out the lever C, the lever 5, will be released,
and the operation of the winding machine will be arrested. It is not necessary to
describe in greater detail these parts, as they may be of any ordinary or suitable
constructions, and as my present invention has no connection with any special
features of construction of such parts, it simply being necessary to have the
parts so constructed that a thread, consisting of two, three, four, or more stands y,
of separate threads brought together, shall be properly conducted to the guide 1,
together laid as a single thread, and wound to form a cop.
The bobbins or cops I, whatever may be their form, containing the strands
which are to be brought and wound together are preferably supported in a ver-
tical position, as shown in Fig. 1. When in the form of cops, as shown, each may
be supported by a spindle 9, Figs. 1 and 2, projecting upward from a sleeve 10,
rocking upon a stationary rod 12, supported by the frame X, the sleeve having a
counterweight 13, which tends to maintain the spindle 9, in an upright position
the sleeve 10, however, rocking outward on the rod 12, when a cop lias to be placed
upon and removed from the spindle 9.
Upon the rod 50, above the cop holders is a series of guide eyes 14, and in order
to bring the spindles 9, of the cop holders directly in line with these guide eyes,
a screw 15, extends through each sleeve 10, and bears with its end against a rod
or bar 16, so that by turning the said screw, each sleeve 10, may be adjusted until
the spindle 9, is directly below one of the eyes.
Each strand of thread y, passes over a tension pad E, of any suitable construc-
tion. As shown, it consists of a metallic plate 17, having a somewhat curved form
and externally covered with a sheet of felt or cloth of such a character as to
cause a certain amount of frictional adhesion as the strand is carried over the
pad. The pad is pivoted about centrally at the back of the plate 17, to a frame F,
which is hung to a cross rod 18, extending between the sides 19, of a frame G.
The frame F', may be raised and lowered in any suitable manner, as for instance
by means of a screw 20, passing through a forked piece 21, pivoted between arms
of the frame F, and embracing a transverse rod 23, the end of the screw 20,
bearing upon an inclined projection 24, upon said rod.
The mean tension must be varied to suit the size and character of the material
wound. To adapt it to these conditions, I raise or lower the pad by means of the
screw 20, so that a greater or less tension surface shall be presented to the thread
and the angle at which the thread leaves the pad to be increased or diminished,
as the case may require. The higher the pad is raised the sharper the bend the
thread must make to reach the guide 14, and it is obvious that the sharper the
bend, the more tension there is on the thread. Having adjusted the pad for the
mean tension by the screw 20, the tension may be still further varied between
certain limits to adjust it to the varying size of the package being wound. The
greater the lineal speed of the thread, the less the tension required, therefore, as
the cop increases in size, the rod 23, is moved to the left and the end of the
screw 20, moves down the incline, allowing the pad to drop. The pad is delicately
counterbalanced by a weight S, adjustable on a rod 80, so that it may adjust
itself to the strands as they are drawn over it. If not counterbalanced, the pad
would assume a nearly horizontal position, so that the thread would draw only
over the edge. The pad may be moved from any part of the machine which is
properly actuated to impart the proper movement to the pad in respect to the
increasing size of the cop. As the counterweight 8, swings to one side as the cop
increases in size, its connection with the rod 23, by a connecting rod 70, serves to
gradually draw out the rod and alter the position of the pad.

page_text: The tension pad may be of any suitable shape, and may be supported in any
suitable manner, so as to be tilted to thereby present an increased frictional sur-
face from time to time as required.
With each strand I combine a stop motion arm or finger of any suitable
character, which is held in position so long as the strand is taut, but which
changes its position if the strand breaks or becomes slack, and is the means,
through other mechanism, of shifting the stop device of the machine, and thereby
arresting the movement of the latter. As shown, the finger 26, is pivoted to a
cross bar 27, upon one edge of a plate H, pivoted midway between the front and
rear edges at 29, to the sides 19, 19, of the frame G, and to the cross pin S at
the rear edge of the plate H, is connected the hook of the rod D.
In order that the apparatus may be sensitive and to avoid strain and variation
of tension upon the threads, it is necessary that the fingers 26, shall be very
light, and that they shall move under very slight influences; but at the same
time, it is desirable that there shall be a positive and powerful movement to
shift the rod D, when it is necessary to arrest the movement of the winding
machine from the slacking or breaking of the threads. I therefore combine with
the stop fingers 26, means for positively actuating the rod 1); and the stop device
connected therewith, which are put into operation by the movement of the
fingers 26, of any one of them. The parts of the apparatus may be differently
constructed to secure this result, but as shown, each finger has connected to it
at the rear an arm 28, with a terminal hook which may engage the teeth of a
toothed or ratchet cylinder 30, driven from any moving part of the machine.
Normally the arm 28, is out of contact with the ratchet cylinder, as shown in
Fig. 4, but should a thread break or become slack, the finger 26, will fall to the
position shown in Fig. 4, and bring the hook of the arm 28, into engagement
with one of the teeth of the ratchet cylinder, and the rotation of the latter will
lift the said arm, and with it the forward edge of the plate H, and draw down the
rod D, and cause the stop device of the machine to act to arrest the latter. It
is not absolutely necessary that the rod 27, shall be carried by the plate H.
shown in Fig. 14, it is intended to be stationary, and supported by the sides 19,
of the frame G, and there is an elongated eye in the hub connecting cach
finger 28 and arm 26, to permit the arm 28, to move upward when its hook
engages the teeth of the ratchet cylinder. Or the finger and its arm may swing
about the stationary rod 27, without other movement, as shown in Fig. 13, but
with a movable sleeve 28, upon the arm 28, having a head which engages with
the teeth of the ratchet cylinder, and is raised thereby, and by its contact with the
edge of the plate H, vibrates the latter. It will, however, be evident that other
connections may be made to secure the positive movement of the stop device upon
the movement of any finger 26, provided the parts be thrown into operation by
the movement of the said finger, the said parts being operated from some posi-
tively operating part of the device. As shown, the ratchet cylinder 30, turns in
bearings of the frame G, and has at one end a pulley 31, over which a band 32
passes to a pulley 33, on the end of the cam shaft 2, of the winding machine.
In order to take up any slack, a belt tightener K, is arranged as shown and
provided with pulleys over which the band 32 passes.
As
To secure the proper adjustment of the parts so that they will operate with
nicety and precision, and instantly upon the slightest slacking of a thread, it is
desirable to put a take-up or extension device at some point of the connections.
When there is a rod I), as described, a turnbuckle L, may be arranged in the line
of the rod and constructed in any suitable way as shown in Figs. 12 and 15 to 18.
As shown in Figs. 3, 4, and 12, the turnbuckle consists of a sleeve 33, threaded
at one end to receive a screw rod 34, and having a perforation at the other end
for the passage of the rod D, which has a head inside of the sleeve and a collar 35
below the sleeve; and a nut 36, Fig. 4, on the rod 34, serves as a binding nut to
hold the parts in place after adjustment. The rod 34, is pivoted to the end of
the arm 4, as shown.

page_text: In order to facilitate inserting the ratchet cylinder 30, in place, I bore in one
side 19 of the frame G, an opening large enough to receive a bushing or bearing
block 37, somewhat larger in diameter than the ratchet part of the cylinder, and
having a recess to admit laterally the journal 38, of the cylinder, the said recess
being open at the bottom and provided with a pad of felt or other like
material 48, which will absorb oil and maintain the journal lubricated. An
inclined orifice 62, Figures 3 & 4 in the other side piece receives absorbent
material which is saturated with a metallic lubricant.
While the fingers 26, with their arms 28, may be made in any suitable manner,
I prefer to construct the same so that each finger and arm will consist of a single
piece of wire, portions of which are coiled to constitute the hub through which the
rod 27 passes, as best shown in Fig. 7. In this case the edge of the plate H, is
cut away to leave intervening lugs 49, which serve to separate the fingers.
