PROVISIONAL SPECIFICATION.
We, JOE BOOTH WHITELEY, CHARLES HENRY WHITELEY and WILLIAM
WHITELEY of the firm of William Whiteley and Sons of Lockwood, near Hudders-
field, in the County of York Machine Makers do hereby declare the nature of our
invention for "IMPROVEMENTS IN SPOOL AND PIRN WINDING MACHINERY" to be as
follows:-
In the present construction of spool and pirn winding machines stationary cups
are employed, in which the spool or bobbin rotates for the purpose of forming or
building the cop thereon, which is effected in a cone shaped form by frictional
contact of the yarn within the cup.
In practice it is found that the surface friction upon the yarn by the continuously
revolving spool within a stationary cup, polishes or gives an undesirable gloss to tho
said yarn especially is this observed when the thread breaks on a partially filled
spool, as the whole weight of the cop is resting and rubbing within the cup until
the broken end is pieced up again.
In addition to glossing the yarn it is frequently broken by being rubbed or
chafed.
The object of our Invention is to avoid the glossing of the thread, and prevent
the breakages referred to, and this we accomplish by the employment of a rotary
cup, revolving at the same speed as the spool.
For the purpose of carrying out our Invention we employ a tube having a cup
at one end, and a wharle at the other for the purpose of giving rotation thereto.
The spindle upon which the spool is placed is passed through the cup and tube, and
by means of a key and groove therein the spindle and spool are caused to rotate
with the tube and at the same speed.
The lower part of the spindle fits into a suitable revolving bearing, supported by
a reciprocatory bar or lifter, for the purpose of giving a reciprocatory motion to the
spindle and spool. The thread to be wound upon the spool passes through a
stationary guide eye close to the upper edge of the cup, and as the spool moves
backward and forward within the cup the thread is wound on the spool in a
conical form, to the extent of its traverse, consequently the spool is built up in a
regular and uniform shape as the end thread enters the cap, at each forward
movement, such forward movement bringing the thread for a moment in contact
with the inside of the cup, but in so doing there is no rotary friction, as the inner
surface of the cup rotates with, and at the same surface speed as the spool.

page_text: At each forward motion of the spool within the cup, the whole surface of the
cone touches the inside of the cup, and in so doing the spindle with the spool
thereon is fed or drawn backward or further out to the extent of the thickness of
the last layer of thread, so that another layer of thread can be wound upon the
preceeding layer, and this is repeated at euch forward movement of the spindles,
thereby feeding or pushing the spool backward as it is being filled with yarn to the
required diameter,
In order to allow the spindle gradually to recedo from the cup and yet rotate ;
the revolving bearing in the reciprocatory bar which supports the spindle is made
in such manner, that whilst its hold of it is sufficient as to reciprocate the spindle,
it permits of its being drawn there through as each successive layer is wound
thereon, and this is effected by having a portion of the revolving bearing split or
cut lengthwise, the outside of which has a conical screw thread thereon for
receiving an adjustable nut for the purpose of increasing the frictional grip of the
spindle.
In order to allow the spool to be put easily on and off the spindle without
removing the said spindle from its position each time the spool is changed, we
attach a swivelling piece or bobbin-catch on the top of the spindle so that when the
spool is placed on the spindle it is prevented coming off by the swivelling part
being placed at right angles to the flange of the spool; a spiral spring being
employed to force the spool up against the swivelling piece.
Instead of employing the swivelling piece for keeping the spool on the spindle a
Bat headed spring attached to the top of the spindle may be used.

We, JOE BOOTH WHITELEY, CHARLES HENRY WHITELEY, and WILLIAM
WHITELEY, of the firm of William Whiteley and Sons, Lockwood, near Hudders-
field, Yorkshire, Machine Makers do hereby declare the nature of our invention
for "IMPROVEMENTS IN SPOOL OR PIRN WINDING MACHINERY," and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
In the present construction of spool and pirn winding machines, stationary cups
are employed, in which the spool or bobbin rotates for the purpose of forming or
building the cop thereon, which is effected in a cone shaped form by frictional
contact of the yarn within the cup.
In practice it is found that the surface friction upon the yarn by the continuously
revolving spool within a stationary cup, polishes or gives an undesirable gloss to
the said yarn, especially is this observed when the thread breaks on a partially
filled spool, as the wholo weight of the cop is resting and rubbing within the cup
until the broken end is pieced up again. In addition to glossing the yarn it is
frequently broken by being rubbed or chafed.
The object of our invention is to avoid the glossing of the thread and prevent
the breakages referred to, and this we accomplish by the employment of a rotary
cup, revolving at the same speed as the spool.
For the purpose of carrying out our invention we employ a tube having a cup
at one end, and a wharle at the other for the purpose of giving rotation thereto.
Such being the nature and object of our invention wo will now proceed to
describe the same more fully and in order to do this we will make reference to the
accompanying sheets of drawings wherein Fig 1 is plan view of apparatus con-
structed according to our invention, Fig 2 cross section taken through the line a.-b.
in Fig 1, and Fig 3 is section through the bobbin and tube for the purpose of
shewing the internal parts. No 1 is framing of machine, 2 the bobbin or spool
which is placed upon the round part of the spindle 3, the remaining part of such
spindle being made square as shewn at 5 and passes through the rotary tube 6 the
front end of which is bell mouthed or formed with a cup 7 and caused to rotate by
wharle 8 as herein after explained. The spindle is made to revolve along with the
tube and therefore at the same speed, and this is effected by means of a key and
groove or by means of the part 9 which has a square hole in it to fit the spindle,
such part 0 being attached to the clutch disc 10 fastened on the tube. In addition
to the spindle having a rotary motion, it also has a backward and forward or
reciprocatory motion, and this is obtained by means of a rack 11 attached to the.
bracket 12 which supports the back end of the spindle, the front end thereof being
supported in the tube by the enlarged part 4. Gearing with the rack 11 is a
segment 13 fixed to the rocking shaft 14 operated by segment lever 15 from any
convenient moving part of the machine. The creel 16 upon which the hank of
yarn is placed is of ordinary construction, the hank being kept at a suitable tension
by lever arın 17, which is weighted at 18. When commencing to wind or build up
a cop upon the bobbin the yarn is passed through the eyelet 19 and placed onto
the spool, the taper end thereof entering and fitting the cup formed on the rotary

page_text: tube. The yarn passes over the edge of the said cup onto the bobbin, and by the
rotary motion of both cup and bobbin the yarn is wound thereon, and as the bobbin
is reciprocated backward and forward by the spindle, the yarn is wound onto the
bobbin in a conical shape to the extent of its traverse, consequently the yarn is
built up into a uniform and regular cone shape. It must be understood that at
each forward motion of the bobbin within the cup, that the whole surface of the
cone touches the inside of the said cup, and for a moment is in contact with it, but
in doing so there is no rotary friction, as the inner surface of the cup rotates with,
and at the same surface speed as the bobbin. As cach layer of thread is wound
upon the bobbin, the cone necessarily gets that much larger, and as stated above,
the whole surface of the cone touches for a moment the inside of the cup, and in so
doing it follows that it cannot enter the cup as far as it could the preceding time
by the thickness of each succeeding layer; provision is therefore made as bereinafter
explained, so as to give out more length of spindle in the same proportion as it is
required, so that as each layer of yarn is wound upon the bobbin, the cone that is
being built up, always fills the cup at each forward motion. The manner of feeding out
more length of spindle is accomplished self-actingly by the cone itself cach time it
enters the cup, and this is effected in the following manner. As will be observed
from the drawings especially in sections Figs 3 and 4 one part of the spindle is
square as seen at 5, but two sides thereof are serrated or cut into fine grooves and
pass through two nippers 20 carried by casting 21 supported by bracket 12. These
nippers are serrated and are kept in contact with the spindle by small spiral
springs c which close the said nippers upon the serrated part of the spindle, but
their hold of it is only slight, for as each layer of thread is wound upon the bobbin
and brought into the cup by the reciprocatory rack 11, the contact of the cone
within the cup is sufficient as to draw the spindle forward as much as the layer of
thread has taken up, and this is repeated each time the cone enters the cup,
consequently whilst the spindle is rotating and reciprocating up and down the
tube 6, it is also being fed forward to suit the increasing size of the cone.
In order that such spindle and tube may stop rotating as the bobbin gets full,
we have arranged self-acting mechanism for this purpose seo enlarged views Figs 4
and 6 whereby any one spindle and tube can be stopped whilst the remainder
are rotating, consequently there is no glossing of the yarn by the cone rubbing in
contact with the cup as is now the case. This part of our invention is effected in
the following manner. Extending from front to back of the machine is a rod 22,
the rear end of which carries a short arm 23 provided with an adjustable stud 24.
Hinged to the bracket 12 is a bell-crank lever 25 the lower end of which is snecked
as shown in Fig 4, and when the spindles aro running, the short arm 23 is
supported on the sneck of the bell-crank lever as shewn in dotted line Fig 4.
The rod 22 is connected by a bracket 20 to another rod 27 carrying an arm or
clutch fork 28 which enters a groove in the driving wharle 8 and capable of being
moved backward and forward on the boss 30 fastened onto the rotary tube. The
wharle 8 moves loosely upon the boss 30 and has projections on its face which when
moved forward take into gear with other projections on the disc 10 also fixed on
the end of the rotary tube. Therefore when the parts are in gear as shewn in Fig 3
and tho spindles running, all is satisfactory, and the spindles are continuously being
moved backward and forward through the tube; as soon however as the bobbin 2
is full of yarn, a disc 32 on the end of the spindle, strikes the upper end of the
bell-crank lever 25 and removes the catch at the other ond thereof from under the
short arm 23, which on being released descends by its own weight, so that the set
screw 24 comes opposite the end of the rod 27 which in its advancing movement
forces forward and carries with it the other rod 22 pushing it so far as to cause
the notch 34 at the end of the said rod 22 to catch onto the framework whereby
it is held until released by the operative. The forward movement of the rod 27 also
causes the clutch fork 28 to remove the driving wharle 8 from contact with the
disc 10, whereby the rotation of the tube and spindle is stopped. When it is
necessary to start the spindle again, the operative twists the rod 22 as shown at 35

page_text: in section Fig 2, the front end of the rod being flattened at 36 for that purpose.
On twisting the spindle as explained the short arm 23 is lifted as shewn in dotted
line Fig 5 whereby the set screw 24 is raised above the rod 27, and on the notch 34
being lifted from contact with the framework the spiral spring 37 immediately
forces the two rods back again, whereby the rotary wharle 8 is connected with the
disc 10, consequently the spindle and tube are set in motion again.
In order to allow the spool to be put easily. on and off the spindle, without
removing the said spindle from its position each time the spool is changed, we
attach a swivelling piece or bobbin catch on the top of the spindle, so that when
the spool is placed on the spindle, it is prevented from coming off by the swivelling
part being placed at right angles to the flange of the spool, a spiral spring being
employed to force the spool up against the swivelling piece, or a screw knob 38
may be employed.
This motion is shewn with the spindle in a horizontal position, we however
would have it understood that they may be either vertical or at an angle, and can
be employed in winding any description of yarn.
