PROVISIONAL SPECIFICATION.
Improvements in Travellers Employed in Ring Spinning and
Doubling Machinery.
1, THOMAS COULTHARD, of Cooper Road, Preston, in the County of Lancaster,
Machinist, do hereby declare the nature of this invention to be as follows:-
This invention of improvements in travellers employed in ring spinning and
doubling machinery consists in so constructing a traveller that it may be heavier at
its inner side, that is to say at that side nearest to the spindle, than at its outer side,
so as thereby to balance the drag of the yarn or thread which, as is well known,
causes the traveller as usually constructed to be pulled upwardly and outwardly and
to traverse the ring with the outer limb of the traveller considerably below the inner
limb, thereby causing the wear upon both the traveller and the ring to be irregular.
This defect has been sought to be overcome by making the rings with bevelled
Hanges and also with supplementary flanges but in practice these are not successful.
Now according to my invention I make an ordinarily shaped traveller with its
inner end turned downwards so as to lay against the web of the ring (instead of
being cut off short or square as usually made), the turned down part serving to
provide the required extra weight to the inner side of the traveller hereinabove
referred to and also to afford an improved system of rubbing or wearing surfaces
between the traveller and the ring.

Improvements in Travellers Employed in Ring Spinning and
Doubling Machinery.
I, THOMAS COULTHARD, of Cooper Road, Preston, in the County of Lancaster,
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 :-
This invention of improvements in travellers employed in ring spinning and
doubling machinery consists in so constructing a traveller that it may be heavier at
its inner side, that is to say at that side nearest to the spindle, than at its outer side,
so as thereby to balance the drag of the yarn or thread which, as is well known,
causes the traveller as usually constructed to be pulled upwardly and outwardly and
to traverse the ring with the outer limb of the traveller considerably below the inner
limb, thereby causing the wear both upon the traveller and the ring to be irregular.
This defect has been sought to be overcome by making the rings with bevelled
flanges and also with supplementary flanges but in practice these are not successful.
Now according to my invention I make an ordinary shaped traveller with its
inner end turned downwards so as to lay against the web of the ring (instead of
being cut off short or square as usually made), the turned down part serving to
provide the required extra weight to the inner side of the traveller hereinabovo
referred to and also to afford an improved system of rubbing or wearing surfaces
between the traveller and the ring.
In order that my invention may be better understood I annex a sheet of drawings.
In each of the Figs. (1, 2 and 3) a represents in section a double-flanged ring to
which is fitted my improved traveller 6 having its inner end b' turned down so as to
provide the required extra weight to the inner side of the traveller and also to afford
an improved system of rubbing or wearing surfaces between the traveller and the
ring hereinabove referred to.
In some cases it is not requisite to provide such an amount of rubbing surface as
is shewn in the examples of my improved travellers and the travellers c (at the
opposite side of the Figs.) shew the weighted part c¹ turned back so that the amount
of rubbing surface may be decreased.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :—
Constructing travellers employed in ring spinning and doubling machinery with
their inner ends turned downwards or weighted substantially as described and shewn
in the drawings for the purpose set forth.
