IMPROVEMENTS IN THE RINGS AND TRAVELLERS USED IN RING SPINNING
Year: 1885

page_text: We JOHN MUIR HETHERINGTON of the firm of John Hetherington and Sons of
Pollard Street Manchester in the County of Lancaster Machine Makers and SAMUEL
THORNTON in the employment of the said firm do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE RINGS AND TRAVELLERS USED IN RING
SPINNING" to be as follows:-
Our Invention relates to the forms and construction of the travellers used in the
spinning of textile materials and has for its objects to increase their efficiency and
durability. We make the traveller of such a form as that it has an increased base
or contact surface extending horizontally or in the plane of its motion or there-
abouts. This increased base keeps the traveller in a more uniformly erect and
better position under the varying conditions of its working. We obtain this
extended base by bending the wire from which the traveller is formed so that
a part of the traveller extends along the under side of the flange of the ring
when the traveller is in working position so that it is not so liable to become
locked or to fall back when the end breaks or when the ends are lowered.
Another advantage possessed by travellers so formed is due to the fact that
owing to the greatly increased surface of the part which is in sliding contact
with the ring the traveller can be continued in use for a longer time than the
ordinary travellers. We prefer to use our traveller in connection with a ring
which has a conical shoulder below the inside flange of the ring. To control
the yarn as it passes to and from the traveller we form the latter with a finger
which separates the approaching and leaving yarn or causes a divergence of the
yarn so that the locking or close coiling of the yarn upon the traveller or the
rubbing contact of one part of the yarn upon another is prevented, what we may
term the spiral turn of the yarn in passing the traveller being lengthened-This
finger also furnishes a means for increasing or regulating the tension of the yarn
the finger being so formed and situated on the traveller as that the yarn can be
bent out of the direct line by the finger on its way to the bow part of the traveller
so that an additional contact is obtained without the disadvantages arising from
passing the yarn completely around any part of the traveller. We form the said
finger by bringing up one end of the wire and bending it over the bow of
the traveller that is to say over the part which crosses the ring or by otherwise

page_text: bending the said end so that it comes over the ring when the traveller is at work
or is brought into such a position as that the yarn will pass in contact with it as
the yarn approaches and leaves the traveller. We make our improved travellers
from round or flat wire and also by punching blanks out of sheet steel or metal
and bending them into the required forms to suit the rings. This latter method
enables us to obtain forms which could not conveniently be produced from wire as
for example we can make the aforesaid base extend either on one side or on both
sides of the limits of the traveller and we can shape the blank so that the bow
part is bent or curved sideways and we can readily form the traveller with more
than one finger so that the yarn can be controlled on its passage both to and from
the bow part of the traveller.

Improvements in the Rings and Travellers Used in Ring
Spinning.
We JOHN MUIR HETHERINGTON of the firm of John Hetherington and Sons of
Pollard Street, Manchester in the County of Lancaster Machine Makers and SAMUEL
THORNTON in the employment of the said firm do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE RINGS AND TRAVELLERS USED IN RING
SPINNING "and in what manner the same is to be perforined to be particularly
described and ascertained in and by the following statement and accompanying
drawings:-
Our Invention relates to the forms and construction of the travellers used in the
spinning of textile materials and has for its objects to increase their efficiency and
durability. We make the traveller of such a form as that it has an increased base
or contact surface extending horizontally or in the plane of its motion or there-
abouts. This increased base keeps the traveller in a more uniformly erect and
better position under the varying conditions of its working. We obtain this
extended base by bending the wire from which the traveller is formed so that a
part of the traveller extends along the upper side of the flange of the ring when
the traveller is in working position so that it is not so liable to become locked or
to fall back when the end breaks or the ends are lowered. We prefer to use our
traveller in connection with a ring which has a conical shoulder below the inside
flange of the ring. To control the yarn as it passes to and from the traveller we
form the latter with a finger which separates the approaching and leaving yarn or
causes a divergence of the yarn so that the locking or close coiling of the yarn

page_text: upon the traveller or the rubbing contact of one part of the yarn upon another is
prevented what we may term the spiral turn of the yarn in passing the traveller
being lengthened. We make our improved travellers from round or flat wire and
also by punching blanks out of sheet steel or metal and bending them into the
required forms to suit the rings.
Our Invention will be most clearly understood when described with reference to
the accompanying sheet of drawings wherein are represented examples of travellers
of our improved formation drawn to a scale of about six times the full linear
dimensions of the travellers selected for illustration. In the said drawings each
traveller is illustrated by means of three Figs.; the first Fig. in each case repre-
senting a front view the second a side view and the third a plan view of the
traveller. In all the examples a represents the increased or extended base with
which we provide our improved travellers b. is the aforesaid finger and c. the
ordinary bow part of the traveller or a part corresponding thereto. The first four
examples represented by Figs. 1 to 12 are supposed to be made from flat steel wire
the two examples represented by Figs. 13 to 18 being made from sheet steel by
punching out blanks of the necessary forms and bending them into the shapes to
suit the purposes of our invention. In the first example represented by Figs. 1
to 3 the part a is formed by extending one end of the wire in a curved form along
the path of motion of the traveller the flat surface of the wire bearing upon the
underside of the flange of the ring which is indicated by dotted lines in Fig. 2.
It will readily be seen that the part a supports the traveller in its proper
working position so that it is not so liable to become displaced or locked as herein-
before mentioned. Another advantage possessed by our traveller is due to the fact
that owing to the greatly increased wearing surface of the part a the traveller is
much more durable and can therefore be continued in use for a longer time than
the ordinary traveller. The length of the part a. may be made greater or less in
proportion than in the indication in the drawings. The wire passes from the
part a over the ring to form the usual bow part c. and is bent downward and
inward below the other and outer flange of the ring and is then bent outward
again so as to form a part d. to bear against the underside of the outer flange this
part d also furnishing an extended wearing surface as compared with the ordinary
traveller. From the part d. the wire is brought upward to form the hooked
finger b. which is an important feature in our invention. The yarn passes under
the finger b. and from the said finger passes to and under or around the bow c. as
indicated by the dotted line e. whence it passes to the bobbin as is usual. By the
addition of this or a similar finger we obtain several advantages. It will be seen
that as the yarn has to pass some little distance from the part b. to the part c. and
is therefore bent out of the direct way to the part c. the yarn when approaching
the traveller is kept well apart from the part of the yarn which is leaving the
traveller as herein before mentioned and also the finger furnishes a means for
increasing or regulating the tension of the yarn by reason of the additional contact
of the yarn with the finger. As hereinbefore mentioned we prefer to use our
improved travellers in connection with rings which in each case have a conical or
inclined shoulder under the inside flange of the ring as indicated at f. in Fig. 5.
The side of the ring section marked X is the inside This shoulder acts in conjunc-
tion with the centrifugal force to keep the traveller in its higher position so that
the bow is prevented from dragging upon the ring and the part a is kept in contact
with the flange of the ring. We do not however confine ourselves to any particular
formation of ring, nor do we confine ourselves to any particular formation of the
traveller so long as the extended surface a and the finger b. or a suitable finger or
hook are obtained. The remaining examples are furnished in order to illustrate
our invention more fully but do not include all of the forms in which our traveller
may be made. In Figs. 4 to 6 the finger is formed by bringing the wire from a.
across the ring again the other end of the wire being extended below the outside
flange of the ring to form the outer bearing surface d. In Figs. 7 to 9 the traveller
is formed with a curl b. which takes the place of the finger in the previously

page_text: described example. In Figs. 10 to 12 the traveller is similar to the one illustrated
by Figs. 4 to 6 but with the principal difference that the finger b. is extended over
the bow part c. We do not confine ourselves to the use of flat wire in the formation
of the traveller as so far described. In Figs. 13 to 15 the blank to form the
traveller is stamped or punched with a projecting limb a and a projecting finger b.
which correspond to the parts a and b. in the previously described examples.. In
Figs. 16 to 18 a limb a projects from each side of the central bow part of the
traveller which is formed with two hooked fingers b. and b¹. The yarn may pass
from one finger to the other either with or without passing under or around the
bow as may be found to be most desirable in practice.
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
"
1. A traveller formed with an extended limb, base or surface to bear against the
under-side of the inner flange or of each flange of the ring substantially as set forth
and indicated with reference to the parts a and b in the accompanying drawings.
2. A traveller formed with a finger, hook or projecting part or with more than
one such part under over or around which the yarn passes on its way to the bow
part of the traveller substantially as and for the purposes set forth and indicated.
3. The travellers of the various forms indicated in the accompanying drawings.
4. The ring of the section indicated in Fig. 5 when used in combination with a
traveller of our improved form substantially as set forth and indicated in the
accompanying drawings.
