PROVISIONAL SPECIFICATION.
Improvements in Winding Machines for Yarn or Thread.
1, ABRAM COMBE of Falls Foundry Belfast, Ireland, Machinist do hereby
declare the nature of this invention to be as follows:-
These improvements relate to the winding of twisted fibrous substances into a
cylindrical form or roll on a spindle with a traverse sufficiently quick to make the
roll hold together when removed from the spindle.
In the construction of machines for the purpose aforesaid, according to this my
invention, the yarn on leaving the spinning bobbin is passed over a barrelled guide,
thence to the roll or spindle where the roll is being made.
The motion of the bobbin from which the yarn is being unwound to form the
roll is controlled by the action of a combined spring and weight drag or brake
which consists of a curved spring pressed against the yarn on the bobbin being
unwound by means of an angled lever and weight the latter of which can be
adjusted to give the amount of drag required; the spring pressing against the yarn
on the bobbin yields to the inequalities of the surface of the yarn without causing
the weight to vibrate materially.
The weighted arm is set at such an angle that when the bobbin being unwound
is full of yarn the spring is made to exert its greatest pressure on the yarn and as
the bobbin decreases in diameter the angle varies so that the pressure also decreases
and thus a uniform and steady drag is obtained throughout the unwinding of the
yarn from the bobbin.

ABRAM COMBE,

I, ABRAM COMBE, of Falls Foundry, Belfast, Ireland, 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:-
These improvements relate to the winding of twisted fibrous substances into a
cylindrical form or roll on a spindle with a traverse sufficiently quick to make the
roll hold together when removed from the spindle.
In the construction of machines for the purpose aforesaid, according to this my
invention, the yarn on leaving the spinning bobbin, is passed over a barrelled guide,
thence to the roll or spindle where the roll is being made.
The motion of the bobbin from which the yarn is being unwound to form the
roll is controlled by the action of a combined spring and weight, drag or brake,
which consists of a curved spring pressed against the yarn on the bobbin, being
unwound by means of an angled lever and weight, the latter of which can be
adjusted to give the amount of drag required; the spring pressing against the yarn

the weight to vibrate materially.
The weighted arm is set at such an angle that when the bobbin being unwound
is full of yarn, the spring is made to exert its greatest pressure on the yarn, and as
the bobbin decreases in diameter, the angle varies so that the pressure also
decreases, and thus a uniform and steady drag is obtained throughout the
unwinding of the yarn from the bobbin.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
Figs. 1 and 2 are sectional elevations of such parts of a winding machine as are
necessary in order to illustrate the application of my improvements thereto.
Fig. 3 is a plan view of Fig. 2.
At 1 is spinning frame bobbin from which the yarn is to be wound upon the roll
spindle 2, succeeding bobbins 1 being applied to the peg 3 and wound from bobbins 1
until the full ** roll 4 is formed.
To ensure the requisite tension or drag on the yarn during the unwinding from
the bobbin 1 to and upon the roll 4, in order that the latter be wound or built with
the desired compactness and firmness, the changing diameter and weight as
between the bobbin 1 when full, and the same bobbin when nearly empty, the drag
or tension on the yarn must be constantly and proportionately altered, which effect
is attained through the blade spring 5, the free end of which, as shewn, bears upon
the yarn on the bobbin 1, its other end being fixed to the short arm of the bell-
crank lever 6, on which is an adjustable weight 7; the said crank lever and spring
exerting their greatest force when acting upon a full bobbin, as seen in Fig. 1, and
a gradually decreasing force is exerted by reason of change of angle of lever, and as
the bobbin 1 is reduced in diameter as shewn by Fig. 2. The yarn from the
bobbin 1 passes over barrelled guide rollers 8, thence to a thread guide 9, and is
wound on the roll 4 through the action of the driving roller 10 as ordinary.
The roller carriage 11, standards 12, weighted lifting and stopping levers 13, 14,
are of the ordinary construction.
It will be seen that the improvements in machines for purpose aforesaid
comprise and combine with "roll" carrying and roll driving rollers of a drag or
brake spring, one end of the latter bearing on and against the yarn on the delivery
bobbin, the other end of said spring being attached to a weighted bell-crank lever,
the latter by reason of its constant changing angle as the yaru is wound from the
bobbin 1, automatically reduces the drag proportionately and to the requirements
of the lightened bobbin.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The general construction, arrangement, and combination of parts illustrated
by Figs. 1 and 2 of annexed drawings.
(2) A blade spring, one end bearing on the yarn on a bobbin, the other end
attached to a bell-crank weighted lever placed at an angle, the yarn passing from
the delivery bobbin over a barrelled guide roller, such as 8, together with rol
spindle and roll driver, all in combination and as herein fully described, and
illustrated by Figs. 1 and 2 of drawings hereunto annexed.
