We, JOHN DANIA TOMLINSON, of Soho Works, Rochdale, Engineer, and
JOSHUA PORTER, of Soho. Works, Rochdale, Works Manager, do hereby declare
the nature of this invention to be as follows;-
-
Our said invention relates to improvements in or applicable to machines for
improvements in or applicable to machines for winding gassing and the like
operations on yarn or threads.
According to our said invention the yarn guide which distributes the yarn
lengthwise along the bobbin or tube is hinged so as to rise as the bobbin or
tube increases in diameter and so as to be lifted by the latter when it is removed
from contact with its driving drum. Besides being hinged for this purpose the
yarn guide is pivoted so as to oscillate about a vertical or approximately vertical
axis when carrying the yarn from one end of the bobbin or tube to the other.
The yarn guide lies freely in a slot of a traverser which is secured to the tra-
verse bar. The said traverser is inclined in such a way that as the bobbin or
tube fills and the yarn guide rises in its slot its point of contact with the sides of
the slot gets farther away from the fulcrum or centre of oscillation of the yarn
guide. Consequently the arc through which the outer end of the yarn guide
Oscillates gradually gets shorter as the bobbin or tube fills. Hence the bobbin
is built up with converging ends.
Above the slot in the traverser in which the yarn guide thus works the tra-
verser has a longitudinal slot or is formed as a stirrup the sides of which are so
far apart as not to act on the yarn guide when the latter is lifted clear of the
lower slot by the bobbin being lifted from the drum either for removal or to
mend the broken yarn. Consequently in this position although the traverse bar
and the traverser continue to travel to and fro the yarn guide remains stationary
or travels so little or so slowly that the attendant can easily re-insert the yarn
in the nick of the yarn guide.
The lifting of the bobbin or tube from its drum is in some cases effected auto-
matically by means of detector mechanism, in other cases by hand.
In some forms of our said invention we put a bridge piece or guard over the
stirrup-shaped traverser or use a suitably shaped ring in place thereof in order
to prevent the yarn guide being lifted too high.

We, JOHN DANIA TOMLINSON, of Soho Works, Rochdale, Engineer, and
JOSHUA PORTER, of Soho Works, Rochdale, Works Manager, 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:-
Our said invention relates to improvements in or applicable to machines for
winding gassing and the like operations on yarn or threads.
In order that our said invention may be more clearly understood we will
describe the same with reference to the accompanying sheet of drawings in all
the figures of which the same letters refer to the same parts.
Fig. 1 is an end elevation of our said invention.
Fig. 2 is a plan.
Fig. 3 is an elevation.
In these figures a is the driving drum, 6 the bobbin, e the yarn guide, d the
traverser, e the traverse bar.
According to our said invention the yarn guide c which distributes the yarn
lengthwise along the bobbin or tube 6 is hinged at el so as to rise as the bobbin
or tube b increases in diameter and so as to be lifted by the latter when it is
removed from contact with its driving drum a. Besides being hinged for this
purpose the yarn guide c is also pivoted so as to oscillate about a vertical or
approximately vertical axis c³ when carrying the yarn from one end of the bob-
bin or tube b to the other.
The yarn guide c lies freely in the slot d of the traverser d which is secured
to the traverse bar e. The said traverser d is inclined in such a way that as
the bobbin fills and the yarn guide crises in its slot its point of contact d
with the sides of the slot gets farther away from the fulcrum or centre of oscilla-
tion of the yarn guide c. Consequently the are through which the outer end
of the yarn guide c oscillates gradually gets shorter as the bobbin or tube fills
with yarn or thread. Hence the bobbin b is built up with converging ends.
Above the slot d¹ in the traverser d in which the yarn guide e thus works the
traverser has a longitudinal slot (Fig. 3) or is formed as a stirrup or ring
of rectangular or other shape the sides of which are so far apart as not to act
on the yarn guide when the latter is lifted above or clear of the lower slot di
by the bobbin being lifted from the drum a either for removal or to mend the
broken yarn or thread. Consequently in this position although the traverse bar e
and the traverser d continue to travel to and fro the yarn guide c remains
stationary or travels so little or so slowly that the attendant can easily re-insert
the yarn in the nick of the yarn guide. The lifting of the bobbin 6 from
the drum may be effected automatically by means of detector mechanism or by
hand in the usual manner.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:-
1. The herein described means for guiding thread or yarn while being wound
for the purpose of gradually diminishing the length of the layers as the bobbin
or tube increases in diameter.

page_text: 2. In a machine for winding gassing and the like operations on yarn or
threads the combination of a doubly hinged yarn guide c, and a traverser d sub-
stantially as and for the purpose set forth and shown.
Dated this 14th day of February 1899.
