We WALTER TWISS GLOVER of the firm of Walter Glover and Company of
Bridgewater Street Salford in the County of Lancaster Engineers and EDWARD
WHALLEY in the employment of the sail firm do hereby declare the nature of this
Invention to be as follows:-
Our Invention relates to winding frames that is to say to the machine employed
in the winding of yarn, thread, or wire upon bobbins or tubes and particularly to the
class of winding machines in which the winding on is effected by frictional contact
of a revolving drum in the first place with the barrel of the bobbin or tube and
afterwards with the yarn wound upon the said barrel. In such machines it is of
advantage that the winding should cease automatically as soon as the bobbin or tube
is filled to the required extent and to accomplish this by simple and effective
means is the object of our Invention. We carry the bobbin or tube by means of a
lever or of levers which is or are mounted upon a fulcrum so as to turn upon such
fulcrum as the filling proceeds. In connection with the said lever or with each or on
of the levers we employ a second lever or a hinged arm which rests upon a support
and which terminates in an incline. As the winding proceeds the end of the second
lever which we will term the stop lever is drawn along the supporting surface until
it reaches the commencement of the incline when it is caused to run quietly down or
along such incline by the pull or pressure of a spring or of a load upon or connected
with the lever. The effect of this quick movement of the stop lever down or along
the incline is to thrust away the lever or pair of levers which carries the bobbin or
tube and thereby to withdraw the latter from winding contact with the drum and the
winding immediately ceases. In a simple arrangement the stop lever is mounted
to turn upon a fulcrum upon a lever frame or upon one of a pair of levers carrying
the bobbin or tube the other end of the stop lever being pressed against a support
by means of a spiral spring. The incline is by preference formed in one piece with

page_text: the said support which is made adjustable upon the rail or framing of the machine.
The said spring tends to press the bobbin or tube toward the drum and thus serves
two purposes.
When applying the motion in the cases wherein the bobbin or tube
is carried by a vertical spindle the part which is acted upon by the yarn-thread or
wire upon the bobbin or tube may be in constant contact or may come into contact
at about the time or a little before the time when the bobbin or iube is filled to the
required extent the stop lever acting to lift the bobbin or tube from contact with
the drum or to disengage the spindle driving motion.

We WALTER TWISS GLOVER of the firm of Walter Twiss Glover and Company of
Bridgewater Street, Salford, in the County of Lancaster, Engineers, and EDWARD
WHALLEY in the employment of the said firm 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 and accompanying drawings :-
..
Our Invention relates to winding frames that is to say to the machines employed
in the winding of yarn, thread, or wire upon bobbins or tubes and particularly to
the class of winding machines in which the winding on is effected by frictional
contact of a revolving drum in the first place with the barrel of the bobbin or tube
and afterwards with the yarn wound upon the said barrel. In such machines it is
of advantage that the winding should cease automatically as soon as the bobbin or
tube is filled to the required extent and to accomplish this by simple and effective
means is the object of our Invention. We carry the bobbin or tube by means of a
lever or of levers which is or are mounted upon a fulcrum so as to turn upon such
fulcrum as the filling proceeds. In connection with the said lever or with each or
one of the levers we employ a second lever or a pivoited arm which rests upon a
support and which terminates in an incline. As the winding proceeds the end of this
second lever which we will term the stop lever is drawn along the supporting surface
until it reaches the commencement of the incline when it is caused to run quickly
down or along such incline by the pull or pressure of a spring or of a load upon or
connected with the lever. The effect of this quick movement of the stop lever down
or along the incline is to thrust away the lever or pair of levers which carries the
bobbin or tube and thereby to withdraw the latter from winding contact with the drum
and the winding immediately ceases.
And in order that our said invention may be properly understood we will now
proceed more particularly to describe the same with reference to the annexed sheet
of illustrative drawings.
Fig. 1 is a sectional view of the upper part of a winding frame or table showing
the essential parts of our invention in side elevation.
Fig. 2 is a view at right angles to Fig. 1.
In the said Figs. the hobbin a which is shown full of yarn, fibre or wire b is
sustained in bearings in a frame which is pivotted to turn freely with or upon a
shaft d mounted in front of the winding frame. The bobbin a whether in a full or
empty condition rests upon a drum e a number of such drums being carried on the
revolving shaft. While the hobbin or the material coiled thereon is in contact with
the revolving drum e the bobbin also revolves and yarn or wire bis coiled thereon
from the reol or from other bobbins or receptacles. The yarn or wire his wound

page_text: regularly upon the hobbin by the action of the reciprocating guide which is mounted
upon a bar which is moved backwards and forwards in the ordinary manner by a
cam or other means as is well understood.
l
We will now describe the means whereby the bobbin is automatically withdrawn
from contact with the revolving drum e when the bobbin has become full or partly
full if desired of yarn or wire. Upon the side of the pivotted frame we mount a
lever i pivotted loosely upon the stud j. Upon the side of the table of the winding
frame or upon a bracket fixed thereto we bolt a fitting the bolt passing through
a slot so that the fitting can be adjusted nearer to or further from the table by
means of the set screw m. It will be seen that this fitting 7 has a flat surface land
an incline and that at the inner end of the flat surface is an abutment 13. The
inner end of the tail of the lever i rests upon the flat surface so long as the bobbin a
remains in contact with the drum e and the said lever end is held down upon this
flat surface by a coiled spring n. When the bobbin is quite empty and it is desired
to fill the hobbin the end of the lever rests against the abutment 3 and it will be
seen that by setting the fitting and consequently the abutment 13 forward, the pull
of the spring n can be relieved to any desired extent and thus the pressure of the
bobbin upon the drum can be adjusted to suit the nature of the material being
wound. When it is desired to partly fill a bobbin the point of the lever instead
of being set against the abutment 3 is set at some point midway between the said
abutment and the point where the incline begins. As the bobbin fills, the head
of the frame e is pushed outward and the end of the lever i is pulled along the flat
surface towards the beginning of the incline. The length of this flat surface is
so arranged that when the bobbin is full the end of the lever has reached the top of
the incline down which it slides in obedience to the pull of the spring n. As the
lever slides down the incline it pushes the frame c further over and raises the
bobbin a and its contents quite clear of the revolving drum e. The rotation of
the bobbin is thereby immediately stopped so that it can be removed and replaced
by a fresh empty bobbin. The frame c is replaced in its former position and the
fresh bobbin brought in contact with the revolving drum e by pressing with the
thumb on the outer free end of the lever i a purchase o for the forefinger being fixed
on the shaft d. The tension of the spring n may be made adjustable by attaching
the lower end to a stud p capable of being set to any desired position in a slot in a
bracket The action of the spring may be suppleinented if desired by a weight
suspended to the frame c as shown in the drawings.
As shown at Fig. 3 the bobbin may be rotated by means of two discs s instead of
the drum e the said two discs being mounted upon the shaft and acting upon the
two collars which confine the bobbin a. Of course in such an arrangen.ent the
stopping of the full bobbin would not be automatic, but even where the lever and
bobbin are thrown back by hand the spring and lever are valuable as means for
detaining the frame and bobbin in their disengaged position.
Fig. 4 shows a ready method of mounting the bobbin for winding purposes.
A running centre driven from a collar in frictional contact with a revolving
disc lies in line with a centre w. This centre is pushed by a spring towards and
into the bobbin so that when the bobbin is placed between the centres it rotates
with the revolving centre u, and can easily be released when full, by withdrawing
the spring centre w.
At the time of making application for provisional protection we contemplated the
application of our invention to the winding of materials upon vertical spindles, cops
or bobbins, but we now make no claim in respect of such an arrangement.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
(1) In machinery employed in the winding of yarns, thread and wire a stop
motion consisting of a lever pivotted upon a swing frame and connected to a spring
the end of the said lever traversing upon a flat surface while the bobbin is filling,

page_text: and sliding down an incline when the bobbin is full or partly full if desired so as to
automatically remove the hobbin out of contact with the driving circumference,
substantially as described and shown.
(2) In machinery of the indicated type the combination of the frame the spring
lever and the fitting for the purposes and constructed arranged and acting
substantially as described and shown.
