Improvements in Cop-winding Machinery.
We, OSWALD LEVER, of 2805 North 2nd Street, Philadelphia, Pennsylvania,
Machinist, and WILLIAM SMITH GRUNDY, of 2809 North 2nd Street, Philadelphia
Pennsylvania Machinist, 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 :-
Our invention relates to cop winding machines, and consists of improvements in
the details of the mechanism and the combination and arrangement of the several
parts, more particularly in the automatic stop motion for throwing the spindle
bearing device out of gear with the driving mechanism after each cop is wound; in
the mechanism for automatically operating the sliding sleeve which supports the
spindle; in the mechanism which controls the form of the cop on the end of the
spindle and drops said mechanism below the plane of the spindle when the cop is
finished therein, and in the tension device between the thread supplying and guiding
devices adjacent to the spindle joint.

In the drawings, A. represents the supporting frame of the machine, and B the
driving shaft on which is mounted cog-gearing B¹ which operates the pulley C
around which passes a belt or band D, the latter also passing around a pulley E which
is formed with or secured to a horizontally arranged sleeve F, which is mounted in
standards FF2 at the top of the frame A and extends in a transverse direction of
the machine, said sleeve being thus rotated by said pulley E. Within the sleeve F
is fitted a sliding spindle G, one end of which is tapering or pointed for holding the
cop, the main length of the spindle being square. The rear end of the sleeve Fin
its interior is made square so that by contact therewith of the angles or corners of
the square portion of the spindle, the latter is adapted to slide with case within the
sleeve and receive rotary motion therefrom. The standards F and F also provide
bearings for a sliding rod or bar H H', which extends in the direction of and
above the spindle G. The opening in the standard F¹ being square, so as to allow
to pass partly through the same and have a slight vertical play, or be recessed and
lowered slightly therein, an enlarged part J which is recessed at a on its under
surface to adapt it to engage with the lower side of the square opening in the
standard F. Around the rod H is a spring K which bears at one end against the
collar of the belt shipper M on said rod, and the other end against the standard F’

page_text: whereby, when the end of the rod H is raised so as to disengage the recess a
from the base of the standard F', the spring K forces the rod forward. The
rod H. His thus slightly raised vertically so as to disengage the recess a from its
engagement with the base of the bearing in the standard F, on the breaking of the
thread during the forination of a cop, by means of the following mechanism. A
standard F3 rises upright from the frame of the machine and supports at its top a
fixed shaft F extending laterally over the rod H, and the spindle G. Upon this
fixed shaft F is supported adjustably by means of a set screw, an angle arm F³ (see
Figure 10). A longitudinal extending arm F is pivoted upon a bolt passing
through the upper end of the angle arm F. Secured in a recess 14 of the arm F
adjustably by a set screw 14, is an arm F7 which extends over the spindle and
carries on its end a guide wheel 15 over which the yarn passes on its way to the
spindle point to form the cop. Between the arm F and the longitudinal portion of
the angle arm F³ is provided a spring K¹; and said arm F has a projection 12
which plays between the shoulders 10 and 11 at the top of the upright portion of
the angle arm. The part H' of the belt shipping rod is secured to the arm F
by any appropriate means, such as the screw rod H2, pivoted at 16 and passing
through a slot 17 in the arm 17 and its operating length controlled by a knot 18
(see Figures 1 and 2). In order to raise the recessed portion A of the rod H out
of engagement with the bearing in the standard F¹ when the cop is finished on the
spindle, there is secured to the spindle a nose or cam shaped piece L, which is
so disposed that when said spindle is run back, said piece L rotating with the
spindle, strikes the projecting portion J of the rod H and so raises the recess A
out of engagement with the standard F whereby the spring K of the rod H is
permitted to become operative and throw the latter forward as described. Con-
nected with the rod H is a belt shipper M, which is adapted to engage with a belt
or band D, the same being formed with a longitudinal projecting arm N which is
so disposed that when the rod H is moved, the shipper following the same, the
arm N strikes a projection P formed on the pulley E and thus the rotation of said
pulley is stopped. The pulley E has a portion of its length, or a connected part,
of reduced diameter, (see Figures 1, 2 and 3) to which portion the belt or band D
may be moved by the shipper M, whereby said belt or band becomes inoperative
and the pulley is relieved of power.
The cop is formed on the end of the spindle G by means of the conical rollers
shown in Figures 4, 5 and 7 or by means of the cup shown in Figure 9. The
normal position of the spindle G at the beginning of the operation in forming the
cop thereon, is shown in Figure 1, the spindle passing through the space between
the pointed ends of the three conical-rollers L, L, L'. These rollers are mounted
loosely on shafts L³ to permit them to revolve freely thereon; the lower one L',
however, (see Figure 7) should have an additional play outwardly upon its shaft.
The shafts L³ upon which these rollers are mounted, are supported as respects the
upper rollers L, L, in slotted arms L' proceeding from the upright plate L, the
lower roller L¹ being supported upon a plate L5 also proceeding from said upright
plate L2. On the front of the frame of the machine is a plate shown in perspective
in Figure 6, in section in Figure 7, and in end view in Figure 8. This plate is
secured to the frame through a slot L' by means of a bolt L10. It has sides L
projecting at right angles, which are slotted vertically and provided with recesses L
at the upper end of said slots. The plate L' supporting the cop-forming rollers
(see Figure 4) is adapted to be moved vertically in the supporting devices shown
in Figure 6 by means of the projecting pins L passing through the slots L' and
supported in the recesses of said slots at the top thereof. In lieu of the said conical
rollers, a cop shaping cup shown in Figure 9, may be employed, said cup as shown
in end view being open at its top and the spindle projecting through the same.
such construction, however the arms 1 of the plate L2 are dispensed with and the
cup supported stationary and in the same plane with the spindle as shown in
Figure 9. An arm R proceeding from the frame of the machine in front thereof
supports a tension device R', the position of which relatively to the machine is shown
In

page_text: in Figure 1, and-the detailed construction of which is shown in Figures 11 and 13 as
follows: A shaft R' proceeding from the arm R supports a pivot frame. R² in
which a latch R³ has its pivotal bearings. The thread leading from the spool to
the spindle passes beneath this latch R³ which is so pivoted that its weight is
greater at one end than the other, and by gravity bears upon and restrains the too
free movement of the thread beneath it. A modification thereof is shown in
Figure 12 in which the latch R³ is provided with an arm R* extending backwards
over the pivot bearing, which arm is provided with a sliding counter balancing
weight R so that thereby the weight of the latch R³ upon the thread may be
adjusted.
Secured in the frame of the machine at right angles with the line of the spindle,
and below the roller supporting plate L, is a horizontal rotary shaft T, upon
which is fixedly mounted an upright arm T which supports at its upper end a
guiding knob T2 and a finger T, by which latter the thread is guided in the
operation of being formed into a cop. This upright arm T' has a vibratory
movement in the direction of the length of the spindle and over the portion thereof
upon which the cop is formed; this action being produced by the rotary shaft T
which is thus in turn vibrated by being fixed to a lever V, the lower end of which
is pivotally attached to a pitman V which is connected with an eccentric strap V2,
which encircles an eccentric W keyed or otherwise secured to the driving shaft B.
The normal position of the spindle is forward, as shown in Figure 6 that is to
say, with its rear end almost flush with the end of the sleeve F. It is retained
adjustably in that position by means of a buffer to which is attached a cord G³
suspending from its other end a weight or bob G². And the buffer a travels in a
railway a.
:-
The operation of the device is as follows
Power being applied to the driving shaft B, the pulley C and eccentric W
are rotated. The driving belt D imparts rotary motion to the pulley E and
consequently to the spindle G. Vibrating motion imparted from the eccentric W
to the lever V through the pitman V₁, whereby a rocking motion is imparted to the
shaft T and a vibratory motion to the arm T' which carries the thread guiding
finger T the thread being previously led from the thread supplying mechanism
under the tension device R, thence over the guiding wheel 15 of the stop
mechanism and thence over the friction wheel T2 of the vibrating arm T thence to
the finger T thereof and thence to that part of the spindle between the conical
rollers L, L, L' and the cam projection L fixed upon the spindle. As the thread
or yarn winds on the spindle the cop is formed, and as the same increases in size, it
bears against the inner face of the cup Q (if that form of cop shaping device is
used) or against the sides of the rotary conical rollers L L L (if that form is used)
and owing to its conical form produced thereby, it forces the spindle rearward in
the direction towards the rod H', so that when the nose or cam L thereof reaches
the projection J the cop is about finished, and the nose L striking this projection
lifts the recessed part A of the rod H out of engagement with the slotted base of
the standard F with which it is interlocked (as in Figure 1) and the spring Kat
once becomes operative to move the rod H forward and thus the parts assume the
position shown in Figure 2. As in normal position (see Figure 1) the belt D
passes around the larger diameter of the pulley E. The movement as last
described of the rod H which carries the shipper M operates to shift the belt D to
the smaller portion of the pulley Ethus slacking the said belt and relieving the
pulley of the power of the same, whereupon the projection P on the pulley strikes
the arm N of the shipper and the pulley is immediately stopped and the spindle G
ceases its rotation. The same action of the parts occur pending the formation of
the cop, if the thread breaks, whereby the arm F is released thereby drawing up
the rod H and lifting its recess A out of engagement with the base of the
standard F. When the
cop is finished a manual movement backwards of the
plate L2 which supports the conical rollers or cop-shaping cup releases its
projections L from the recesses L' in the vertical slots of the plate L and permits

page_text: said plate L2 to drop downwards in the slots carrying with it the conical rollers or
cop shaping cup to a point below the line of the spindle, and thereby enables the
finished cop to be removed from the spindle. To form the second cop, the yarn is
strung upon the machine as before stated, and the operation proceeds to form a
second cop similarly as described with relation to the first.
