Improvements in Winding Yarn or Thread and in Machinery
for the Purpose.
I HENRY CHEETHAM HILL, of Holly Bank, Mottram Road, Stalybridge, in the
County of Chester, Cotton Spinner, 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 winding yarn or thread on to spools without heads, the
yarn or thread when wound on to the spool being a cylinder with ends square to the
axis or nearly so, or to winding yarn or thread on the cone form on spools without
ends. In such winding, the traverse of the thread must be quick to make firm ends,
and in such cases the thread at times traverses once to and fro in one revolution of
the spool or hobbin.
When the yarn or thread has to be unwound from such bobbins say for warping
purposes and the bobbins have to rotate on their axis to deliver the thread, as some
prefer, the uniform drawing off the thread causes the bobbin to rotate fast and slow
and this produces slack threads which snarl in some cases and become entangled
with adjoining threads and this causes breakage and waste.
The object of my invention is to remedy this defect and yet produce a firm square
or nearly square ended bobbin on a barrel without heads.
I accomplish the object of my invention by a short traverse, but cause this traverse
to change gradually or in step until it covers the entire length of the spool or barrel,
and then travel back again and so on, from end to end, but the traverse dwells longer
at the two ends of the spool than at the other parts to make a cylindrical bobbin of
yarn or thread.
I accomplish this mode of winding by the slit drum (known as Hill and Brown's
system) by using a narrow slit drum, and arranging the bobbin carrying mechanism
and shaft to slide end ways to and fro, giving end movement to it to cause the spool
to move to and fro across the slit drum, by a cam, similar to an ordinary traverse
motion, but the can is shaped to produce the traverse above described, that is, to
dwell at each end of the traverse, or any other equivalent or suitable mechanism may
be used.
I also carry out my invention by an ordinary traverse motion, but by one having a
short traverse combined with mechanism for gradually changing the position of the
traverse, or changing it in steps, to cause it to cover the full length of the bobbin ns
above explained, this additional mechanism is or may be a cam or other equivalent
mechanism operating to change the position of the traverse.
Fig. 1 is a partial front elevation, and fig. 2 a partial end elevation, illustrating

page_text: mechanism for carrying out my invention by means of the slit drum on the Hill and
Brown system.
Fig. 3 is a view of a cylindrical spool or hobbin of thread, the spool being without
heads or ends wound according to my invention.
a is the framing, a cross rails of the framing b, the first motion shaft, rotating in
suitable bearings, which shaft is driven by an endless belt, working upon ordinary
fast and loose pulleys, on the shaft b, at one end of the frame.
On this shaft b, there is a grooved pulley for each slit drum to be driven, and
there is an endless driving band working on the grooved pulley 6, and upon a
pulley c secured on the shaft e² for the slit drum c.
. The shaft or axis of each slit drum rotates in brackets a², secured to the cross
rail framing.
One bracket a³ is or may be arranged to carry one end of the shaft of two adjoin-
ing slit drums.
The two halves of each slit drum are separately secured upon the axis c² leaving a
zig-zag slot or space or slit between them for the thread.
The yarn or thread a passes from the cop, bobbin or hank through a guide wire d
on a rail a³ then between the slit in the drum c and on to the spool e, the periphery
of which rests upon and is rotated by the cylindrical periphery of the slit drum.
Ench spool upon which the thread is wound, is upon a spindle, the ends of which
are in two arms connected by a cross web, thus forming one frame which is centered,
and can oscillate upon a traverse bar or rod that passes from end to end of the
frame, and is carried in brackets a', which form bearings in which the traverse bar
can be slided to and fro endways.
This traverse rod g has arms g secured upon it in which another rod g² is carried,
which rod² serves to support the frame f carrying the spool when lifted clear of the
slit drum c, the lever handle jointed to the frame f having a book that catches
upon the rod when the frame is lifted high enough, and when the lever handle/1
is moved, the hook or recessed part is released from the rod g² and the periphery of
the spool is then allowed to come upon and be rotated by the periphery of the slit
drum c.
There is a bracket (not shown) from any convenient part of the framing, the edge
of which is parallel to the axis of the slit drum and the thread as it comes from the
slit drum, and passes on to the spool e is guided by the edge of the said bracket or the
thin plate secured to it.
This guiding edge is similar to that described in the specification of Letters Patent
granted to myself and Henry Hill Brown No. 5532 1883 and marked ƒ in the
drawings annexed to the said specification.
This guiding edge may be formed by a plate (see fig. 2) carried upon the rod g
the length of each plate being a little longer than the length of that part of the chase
of the spool filled with thread, the front edge of the plate being parallel to the axis of
the spool.
The traverse rod g is made square at one end and slides through a square hole in the
bracket carrying it at one end to prevent the traverse rod from rotating but this rod
may be prevented from rotating by an arm secured upon the rod, a hole in this arm
sliding upon a fixed stud in the bracket carrying the traverse rod or by other means.
As shown in the drawings there is a toothed rack g³, secured upon the traverse rod g
which gears with a wheel i secured to the boss of a wheel on a stud in a bracket a³
which last named wheel i¹ gears with a toothed segment, formed on a lever having
its stud or fulcrum at on the bracket carrying the studs for the wheels and .
The arm of the segmental lever has a slot in it for a stud to carry a bowl i
which works against the edge of a drum cam secured upon the inner end of a
short shaft having its bearings in a suitable bracket carried upon the framing.
The outer end of this short shaft has a ratchet wheel secured upon it, and an
is arranged to oscillate freely on the end of the short shaft in a slot in which
a stud is secured to carry a pawl having a weighted tail to keep the pawl

any suitable bracket a², this wheel gearing with a pinion on the first motion
shaft The crank pin jis jointed with one end of a connecting rod the other end
of which is jointed with the arm carrying the ratchet pawl.
It will thus be seen that the drum cam is rotated intermittently one or more teeth
of the ratchet wheel at each revolution of the crank-pin j.
A brake is or may be arranged in slides to be pressed by a spring against the
edge of the periphery of the drum cam to prevent it from moving between
the times of being acted upon by the ratchet pawl.
A bell crank lever g' having its fulcrum g on a bracket a on the framing has one
horizontal arm weighted to bring a slot in the other vertical arm against a pin in the
traverse rod y, and this keeps the bowl in the segment lever pressed against the
drum cam.
This cam is shaped so as to traverse the rod g to and fro once at each revolution
of the cam but after each movement there is a pause-and the full length of the
spool is divided say into half inches, there is a pause after every movement of one
half inch, the thread being traversed to and fro upon that half inch by the split drum
during the pause, but at that half inch at each end the pause must be double the time
of the others if the thread is to be wound in the cylindrical form as shown in fig. 3,
the dotted lines 1, showing the pauses, the two end divisions having double the
duration of the pauses to the other parts between the two ends.
The drum cam may be driven slowly and uniformly but shaped to make pauses,
or the cam may be shaped to make a slow traverse from end to end of the chase and
to and fro, but to move slower at the two ends.
The mechanism illustrated in figs. 1 and 2 has been arranged for winding spools of
different lengths, and it will be obvious that it may be varied and made more simple
without departing from my invention, especially when arranged to wind spools of
thread of an unvarying length of spool or chase.
Fig. 4 is a front elevation, and fig. 5 an end elevation of so much of a winding
machine as will be necessary for illustrating the mode of winding thread upon spools
without heads or ends according to iny invention without using the Hill and Brown
slit drum.
The spools upon which the thread is to be wound are carried in a frame so that
their peripheries will each rest upon and be rotated by the periphery of a drum as in
ordinary dram winding machines, and the threads are or may be guided upon each
spool when winding in the ordinary manner except, that the traverse rod will have
imparted to it a short quick to and fro oscillation and a slow traverse or a traverse in
steps to and fro, from end to end of the chase of the spool, the slow traverse making
a longer pause at each end as herein before explained in reference to the split drum
modification illustrated by figs. 1, 2 and 3.
The mechanism for carrying out this part of my invention may be greatly
varied while effecting the winding of the thread upon the spools according to my
invention.
As illustrated each driving drum c is upon a separate shaft which is carried in
brackets a² from the framing, and a grooved pulley el secured to the drum shaft is
driven by an endless band working upon a pulley 6' on the first motion shaft b.
The drums for driving the spoolse may be mounted upon a shaft passing from
end to end of the framing as in ordinary drum winding machines. g is a traverse
rod which is mounted in stands or brackets a secured to the framing to slide freely
endways to and fro therein.

The lever may be a bell crank lever, and its horizontal arm in such case is
weighted to keep the bowl against the face of the cam i³.
The drum cam shaft is rotated intermittently by a crank pin, in a wheel j
driven by a pinion on the first motion shaft b, a connecting rod 1, lever arm 28,
ratchet pawl and ratchet wheel, as described in reference to figs. 1 and 2; and
the cam is shaped as herein before explained to produce the step by step and to
and fro movement of the traverse rod as explained by reference to figs. 1 and 2,
and fig. 3.
The brake used to hold the shaft after each movement by the ratchet pawl
may be a brake and spring as described in reference to figs. 1 and 2, but in this
case a brake pulley is secured upon the end of the shaft and one end of a belt jo
is secured to a stud (not shown) fixed in the end framing, this belt j being passed
over the pulley j and having a weight suspended upon it.

The lower end of the lever comes into the groove in a drum cam kon
shaft, having its bearings in brackets secured to the traverse bar g consequently
the shaft moves to and fro with the traverse bar.
The shaft has a long drum upon it upon which an endless band kª works,
that also works in a grooved pulley on the axis of the drum which rotates the
spool.
Thus arranged the lever receives a short and rapid to and fro motion from the
cam and is at the same time traversed to and fro step by step (with a pause
"of the thread
between each step by preference) from end to end of the "chase
upon the spool.
The oscillatory movements given by the cam to one lever, may be transmitted
from lever to a corresponding lever for each drum by a connecting rod or wire
sufficiently strong and of little weight and a spring at one ond of the frame is or
may be used to keep the wire stretched and give the oscillatory movement in one
direction.
The quick oscillatory movements may also be given to a series of levers, corre-
sponding to the lever carried on the traverse rod, one for each winding drum c by
other arrangements of mechanism without departing from my invention for winding
thread upon spools without heads or ends and obviating the objection to a long and
rapid cross traverse hereinbefore referred to.
Cops have been formed upon spools without ends or heads but they are built up,
the thread gradually spreading in the lengthway of the spool and the ends are not
square to the axis of the spool, and the thread is not distributed from end to end of
the chase and wound in a form increasing in diameter from the beginning to the end
of the winding.
Having now particularly described and ascertained the nature of iny said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is.
1. The winding of thread on
quick
to spools without heads or ends with a
oscillatory traverse which is changed in position so as to be moved at intervals or
slowly from one end of the full length of the chase of the thread upon the spool to
the other end and so on, to and fro, substantially as hereinbefore described.
