I, HENRY TETLOW, of Varley Street, Miles Platting, Manchester, in the County
of Lancaster, Heald and Wire Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My said invention relates to improvements in and in the construction of ring
travellers used to impart twist to the yarn in ring spinning and doubling frames
as is well understood.
These travellers are usually made from wire, bent to a C or similar shape. It
has been proposed, in order to obtain strength and ease of running of such travellers,
to flatten the wire on two sides, the other two sides being rounded. When the
wire is so bent to form the travellers, that these rounded edges lie at right angles
to the ring, a little less resistance is offered to the atmosphere, whilst when the
reverse disposition of the flat faces takes place and one rounded edge bears against
the ring, the friction between the ring and traveller is reduced.
My invention has for its object to produce a traveller which shall offer a minimum
of resistance to the atmosphere and shall set up a minimum of friction by its con-
tact with the ring.
According to my invention I form the traveller from a section of wire having
two faces, one perfectly flat, and the other rounded or of a suitable convexity.
When a traveller formed from wire of such section is in use, the rounded or con-
and a
vex face bears against the ring, the flat face lying away from the same,
thin edge is presented on either side to the atmosphere.
When a traveller so constructed, the inner rounded parts set up little or no
friction by contact with ring and the feather edge formed by the meeting of the
flat and curved face offers very little resistance to the atmosphere and is sensi-
tive to the pull of the yarn, so that a traveller is produced which is in every way
most suitable for the purpose. In addition, a traveller constructed of wire of the
indicated section will be found to be extremely strong transversely, whilst less
breakage of the yarn occurs by reason of the rounded surface over which the yarn
passes not being liable to cut the yarn as in cases where the traveller is flattened
on both sides.

I, HENRY TETLOW, of Varley Street, Miles Platting, Manchester, in the County
of Lancaster, Heald and Wire Manufacturer, 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 and accompanying
drawings:-

as is well understood.
These travellers are usually made from wire, bent to a C or similar shape. It
has been proposed, in order to obtain elasticity to spring the traveller on the ring
and secure strength and ease of running of such travellers, to flatten the wire on
two sides, the other two sides being rounded. When the wire is so bent to form
the travellers, that these rounded edges lie at right angles to the ring, a little less
resistance is offered to the atmosphere, whilst when the reverse disposition of the
flat faces takes place and one rounded edge bears against the ring, the friction
between the ring and traveller is reduced.
My invention has for its object to produce a traveller which shall offer a mini-
mum of resistance to the atmosphere and shall set up a minimum of friction by
its contact with the ring and the yarn.
According to my invention I form the traveller from a section of wire having
two faces, one perfectly flat, and the other rounded or of a suitable convexity.
When a traveller formed from wire of such plano-convex section is in use, the
rounded or convex face bears against the ring, the flat face lying away from the
same, and a thin edge is presented on either side to the atmosphere.
The accompanying sheet of drawings clearly indicates my invention.
Fig. 1 represents the improved section of wire drawn to a greatly enlarged scale.
Fig. 2 indicates a traveller of a doubling machine also enlarged made from the
improved section of wire.
Fig. 3 is a ring spinning traveller formed from such section.
With a traveller so constructed, the inner rounded part a sets up little or no
friction by its contact with ring represented by the line b and the feather edge c
formed by the meeting of the outer flat face d and curved face a offers very little
resistance to the atmosphere and is sensitive to the pull of the yarn, so that a
traveller is produced which is in every way most suitable for the purpose. In
addition, a traveller constructed of wire of the indicated section will be found to be
extremely strong transversely, whilst less breakage of the yarn occurs by reason
of the rounded surface a over which the yarn passes not being liable to cut the
yarn as in cases where the traveller is flattened on both sides.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is;-
1. The improved section of wire having a rounded inner face a and flat outer
face for use in the manufacture of travellers for ring spinning and doubling
machinery substantially as described and illustrated.
2. The manufacture of travellers for ring spinning and doubling machinery
