PROVISIONAL SPECIFICATION.
Improvements in Drum Winding Machinery for Yarn.
1, WILLIAM WHITELEY, of the Firm of William Whiteley and Sons Limited,
of Lockwood, near Huddersfield, Yorkshire, Machine Makers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to machinery for winding yarn into conical cheeses or rolls
used in knitting frames for the hosiery trade and also in warping mills. When
yarn is being pulled off these conical cheeses the latter occupy a vertical position
and when the yarn is "crossed" at the bottom of the roll (which crossing arises
from defective machinery) the said yarn breaks as it cannot bear the tension of
the strain.
The object of this invention is to prevent the crossing of the yarn and therefore
avoid the breakages complained of.
In carrying out my invention the carriage or cradle in which the conical cop
is mounted, is placed loosely on its shaft and is made to have a slight lateral or
endwise motion during the time the winding is proceeding the effect of which is,
that the shape of each end of the roll or cheese is bevilled, convex and concave
respectively, whereby the crossing of the yarn is avoided.
In order to give the cradle or frame the endwise motion I arrange that the said
frame when it rises (on the gradually increasing diameter of the roll as each layer
of yarn is wound upon it) that the said frame shall come into contact with an
incline or cam surface whereby the said frame is gradually moved end wise taking
the roll or cheese with it and as the length of traverse of the yarn is always the
same each end of the roll is bevilled.
In order to keep the frame against the cam and so prevent vibration of the
parts, a spiral spring is employed to force the frame continually in contact with
the cam but the said spring could be dispensed with and a box cam employed;
whilst on the other hand the shaft on which the frame is mounted may be grooved
spirally and the cradle attached to a nut working on the said spirally grooved shatt
for the purpose of obtaining the end wise movement of the cradle.
My invention also relates to the combination of a stop motion with drum
winding frames to prevent the glazing of the roll on the absence of yarn.
To carry out this part of my invention a suitably shaped lever arm is employed
at the back of the winding drum, the upper end of the said lever arm being about
on a level with the top of the winding drum. A looped wire or pin rests on the
yarn at a point before it reaches the winding drum and if the yarn fail the looped
wire is no longer supported but falls between a pair of revolving rollers one of
which is loose in its bearings, consequently, when a loop passes between these
rollers the loose one through an arrangement of levers and rods, causes the upper
end of the lever arm to slip between the top of the winding drum and the conical
cheese whereby the said cheese is lifted from contact with the winding on drum,
consequently, the glazing of the yarn is prevented, and this action takes place
every time the yarn is absent when the machine is at work.

I, WILLIAM WHITELEY, of the Firm of William Whiteley and Sons, Limited,
of Lockwood, near Huddersfield, Yorkshire, Machine Makers, 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 :-
This invention relates to machinery for winding yarn into conical cheeses or rolls
used in knitting frames for the hosiery trade, and also used in warping mills.
When yarn is being pulled off these conical cheeses, the latter occupy a vertical
position and when the yarn is "crossed" or overlapped at the bottom of the roll
(which crossing arises from defective machinery) the said yarn breaks as it cannot
bear the tension of the strain.
The object of this invention is to prevent the crossing or overlapping of the
yarr at the bottom or large end of conical cheeses and therefore avoid the breakages
complained of.
In order that this invention may be clearly understood, I will make reference to
the accompanying sheet of drawings, wherein
Fig. 1 is a cross section of the upper portion of a drum winding machine having
my improvements applied to it. Fig. 2 is a plan view thereof, and Fig. 3 front
elevation of same.
A represents the winding drums secured to shafts mounted in the framework of
the machine. The yarn to form rolls or conical cheeses is wound upon a conical
paper tube B shewn clearly in Fig. 4. Each conical paper tube is placed onto a
manndrill which is afterwards mounted in suitable bearings in carriages or cradles C,
such cradles being placed loosely on the stationary shaft D. Each of these
cradles is made to have a slight lateral or endwise motion during the time the
winding of the cheese is proceeding. The effect of this end wise motion is to form
the end of each roll or cheese in a bevelled or convex and concave manner
respectively, (see Fig. 4) whereby the crossing or overlapping of the yarn is.
avoided.
In order to give the cradles or frames C the necessary endwise motion for
bevelling the ends of the cheese or roll, I arrange that each frame as it is rising
with the gradually increasing diameter of the cheese or roll (as each layer of yarn
is wound upon it) that a small pulley a attached to the carriage or cradle C shall
ride in contact with a fixed incline or cam surface E whereby the said carriage or
cradle is gradually moved end wise in the direction of the arrows shewn in Fig. 2
taking the roll or cheese with it, and as the length of traverse of the yarn is
always the same each end of the roll is bevelled as shewn, the tapering of each roll
being the same.
In order to keep the carriage or cradle C against the cam E, and also to prevent
vibration of the parts, a spiral spring F is employed to force the pulley a of the
carriage or cradle C continually into contact with the cam E; but the said spring
may be dispensed with and a box cam employed instead, whilst on the other hand,
the shaft D on which the carriage is mounted may be grooved spirally, and the
carriage or cradle attached to a nut, working on the said spirally grooved shaft for
the purpose of giving end wise motion to the cradle.
Grepresents a guide attached to the reciprocating guide rod H which is employed
to give the traverse to the yarn in the ordinary manner.
My invention also relates to the combination of a stop motion with drum winding
frames to prevent glazing of the roll on the absence of yarn through breakage or
otherwise.
In carrying out this part of my invention a suitably shaped lever arm 1 is employed
at the back of each winding drum, the upper end of the said lever arm being about

page_text: on a level with the top of the winding on drums as the drawing shews. A looped
wire or pin 2 rests on the yarn at a point before it reaches the winding drum, and
if the yarn fails the looped wire 2 is no longer supported, but falls between a pair
of revolving rollers 3 and 4 consequently when a loop or pin passes between these
rollers, the inner one is caused to move away from its adjoining roller, causing the
horizontal rod 5 to be moved in the direction of the arrow at the left hand side of
the machine in Fig. 1.
This endwise movement of the rod 5 causes the bell-crank
lever 6 to rock on its fulcra whereby a sneck on one end thereof is withdrawn from
a stop piece 7 projecting from weighted lever 8. The effect of the weighted
lever falling, is to cause the upper end of lever 1 to pass underneath the roll or
cheese which is lifted from contact with the winding on drum, as shewn on left
hand side of Fig. 1, consequently the glazing of the yarn prevented and this
action of lifting the roll from contact with the drum takes place every time the
yarn is absent.
The right hand side of the machine, Fig. 1, shews the position of the parts when
the yarn is intact.
Having now particularly described and ascertained the nature of my said.
invention and in what manner the same is to be performed, I declare that what I
claim is:-
Firstly. In machines for winding conical cheeses or rolls, the combination
therewith of a carriage cradle or roll-holding frame having a lateral movement
for preventing the overlapping of yarn at large end of the cheeses or rolls,.
operating substantially in the manner described and shewn in the drawings.
Secondly. In a machine for winding conical cheeses or rolls, the combination
therewith of the cradle C, cam surface E, and spring F, or their equivalents, for
imparting end wise motion to the cheese or roll.
Thirdly. In a machine for winding conical cheeses or rolls, the combination
therewith of the lever 1 and parts connected therewith for lifting the conical
cheese from contact with the winding on drum, all arranged and operating in the
manner herein described and shewn in the drawings.
Dated this 15th day of June 1894.
