Improvements in Yarn Winding Machinery.

page_text: Improvements in Yarn Winding Machinery.
We, JAMES GORDON and JOHN MACLAREN MALLOCH, of Blackness Foundry,
Dundee, in the County of Forfar, North Britain, Engineers, do hereby declare
the nature of this invention to be as follows, that is to say:-
This invention comprises improvements in machines for winding yarn into
rolls, the object being to maintain such a tension of the yarn that the roll may
be built to hold together, and that it may be of the correct shape.
In the construction of machines for the purpose aforesaid, the yarn on leaving
the spinning bobbin is passed over a horizontal oscillating guide rail, preferably
controlled by a spring, and the rail is free to oscillate in a horizontal plane
under the influence of the tension of the yarn, and is preferably rounded, the
yarn passing thence to the roll or spindle where the roll is being made. The
motion of the bobbin from which the yarn is being unwound is controlled by a
combined angled spring and weight drag of ordinary construction.
The oscillating motion of the guide rail is such that it enables a nearly con-
stant length of thread as between spinning bobbin and traversing thread guide
to be maintained, while the horizontal face of guide rail is such that the relative
levels of thread and thread guide are constant. The spring preferably employed
is such that it will enable the oscillating guide rail to take up any slack of
yarn on the spinning bobbin should such occur at the instant of the reversal of
the traverse motion, and so prevent what is technically called winking."

We, JAMES GORDON and JOHN MACLAREN MALLOCH, of Blackness Foundry,
Dundee, in the County of Forfar, North Britain, Engineers, 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 comprises improvements in machines for winding yarn into
rolls, the object being to maintain such a tension of the yarn that the roll may
be built to hold together, and that it may be of the correct shape.
And in order that our said invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory draw-
ings to be hereinafter referred to in describing our improvements.

page_text: Figure, 1, of the drawings is a plan, Figure 2 is a front elevation, and
Figure 3, is a side elevation, partly in section, of the improvements. In these
drawings the same reference letters are used to mark the same or like parts
wherever they are repeated.
In carrying out the invention there is provided a horizontal guide rail, A,
which is fitted to oscillate on a pivot or stud, B, fixed to a lug, C, on a bracket, D,
fixed to the framing of the machine, the rail, having preferably a rounded or
circular face, E. The rail, A, is free to oscillate in a horizontal plane, and is
controlled preferably by helical springs, G, which engage in sockets, H, J,
formed respectively in the rail and in upwardly extending arms, K, L, of the
bracket, D. The spinning bobbin, M, from which the yarn is unwound and
which is shown only in Figure 3, is fitted to rotate on a spindle, N, fixed to
the lower end of the bracket, D, and its motion is controlled by a combined
angled spring and hinged weight drag of ordinary construction the spring, 1',
and weight, Q, being hinged on a bracket, R, fixed to the bobbin bracket, I).
The yarn on leaving the spinning bobbin, M, passes over the rounded guide face,
E,, of the rail, A, and from thence it proceeds through the traversing thread
guide, S, to the roll spool, T, on which the roll, U, is formed by the action of the
roll driver, V, in the usual manner. The spool, T, and traversing guide, S,
are shown only in Figure 3, the traversing guide being constructed and driven
in any well known way. As the winding proceeds the guide rail, A, oscillates
under the influence of the tension of the yarn and this movement of the rail
results in causing a nearly constant length of thread, as between the spinning
bobbin, M, and traversing guide, S, to be maintained, while the horizontal form
of the rounded guide face of the rail, A, causes the relative levels of the thread
at the face, E, and at the traversing guide, S, to remain constant.
The spring
controllers, G, enable the oscillating guide rail, A, to take up any slack of yarn
on the spinning bobbin, M, should such occur at the instant of the reversal of
the traverse motion, and so prevent what is technically called " winking."
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
In yarn winding machinery a spring controlled horizontal oscillating guide
rail constructed arranged and operating substantially as and for the purposes
herein before described with reference to the accompanying drawings.
