PROVISIONAL SPECIFICATION.
Improvements in Machinery for Winding Yarn or Thread.
We, FRANK STEWART SANDEMAN, and FREDERICK DAVID STEWART
SANDEMAN, of Stanley Cotton Mills, Stanley, in the County of Perth, North
Britain, Manufacturers, do hereby declare the nature of this invention to be as
follows, that is to say :-
This invention relates to yarn winding machinery in which a quick traverse
motion is employed such motion being obtained by means of a split drum or
otherwise, and in which the yarn or thread is drawn end ways off stationary
bobbins.
The object is to prevent the yarn or thread from catching on or being retarded by
the head or end disk of the bobbin, especially when the diameter of the yarn or thread
on the bobbin has become less than the diameter of the end disk. The invention
consists in covering or shielding the end disk of the bobbin by a conical or curved
cap which is either free to rotate on a spindle or is fixed on a spindle which is
driven at a suitable speed. Or a light fyer or pair of flyer arms with yarn or
With the describe l
thread guides at their ends may be substituted for the cap.
improvement or addition liability to breakage of the yarn or thread from ts
catching on or being retarded by the end disk of the bobbin is done away with.

We, FRANK STEWART SANDEMAN, and FREDERICK DAVID STEWART
SANDEMAN, of Stanley Cotton Mills, Stanley, in the County of Perth, North
Britain, Manufacturers, 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, that is to say:-
:-
This invention is applicable to yarn winding machinery in which a quick traverse
motion is employed, such motion being obtained by means of a split drum or
otherwise, and in which the yarn or thread is drawn end ways off stationary
bobbins. The invention is also applicable to yarn winding machinery in which
various rates of traverse motion are employed.
The object is to prevent the yarn or thread from catching on, or being retarded
by the head or end disk of the bobbin, especially when the diameter of the yarn
or thread on the hobbin has become less than the diameter of the end disk. The
invention consists in covering or shielding the end disk of the bobbin, by a conical
or curved cap, which is attached to a spindle driven at a suitable speed.
Aud in order that the said invention and the manner of performing the same
may be properly understood, we hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing the improvements in machinery for
winding yarn or thread.

page_text: Figure, 1, of the drawings is a transverse vertical section of a winding machine
to which the improvements are applied.
Figure, 2, is an enlarged vertical section of a bobbin and accompanying details.
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 we cover or shield the upper end disk of the
bobbin, A, off which the yarn or thread is drawn by a cap, B, which may be
externally of a conical form as shown at the left-hand side in Figure, 1, or of any
suitable curved form such as that shown at the right-hand side of Figure, 1, and in
Figure, 2, and which fits on the upper tapered end of a spindle, C, driven at a
suitable speed, the cap moving with the spindle, and being capable of being lifted
off the spindle for the purpose of changing the bobbin. The spindle, C, is carried
by a collar rail, D, and a footstep rail, E. In the modification shown in Figure, 2,
part of the spindle, C, is encircled by a sleeve. G, which passes centrally through
the bobbin, A, and is formed with a flange, H, for the bobbin to sit upon, the
sleeve further passing through the collar rail, D, and being fixed to it by a screw
nut, J. The sleeve, G, is arranged to bear on the spindle, C, only at the ends.
The spindle, C, has fast on it a pulley, L, driven by a cord from a drum or
cylinder M, arranged and driven in a usual manner. The bobbin, A, is not in
contact with the revolving spindles, C, and remains stationary. With the described
improvement or addition the delivery of the yarn or thread from the bobbin is
rendered smoother and more uniform and liability to breakage of the yarn or
thread from its catching on or being retarded by the end disk of the bobbin is
done away with.
In some cases the tube, G, may be made shorter than as shown in Figure, 2, or
it may be dispensed with altogether, the bobbin being prevented from rotating
with the spindle, C, by one or two pins engaging in a hole or holes in the collar
rail D.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
In winding machinery in which yarn or thread is drawn end ways off stationary
bobbins, the application to each bobbin of a cap in contact with the outer part of
which the yarn or thread moves in leaving the bobbin, the said cap being
removably fitted upon a suitably driven spindle extending through the bobbin
substantially as herein before described.
