Improvements in Travellers for use in Machinery or Apparatus for
Doubling Cotton, Wool, Silk, and other Fibrous Materials.
We, JOHN HILTON YATES, of Ashbourne in the County of Derby, Manager,
and PETER EADIE, of 12 High Street, Paisley, in the County of Renfrew,
Traveller 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 :-
Our invention relates to travellers used in machinery or apparatus for doubling
cotton, wool silk and other fibrous materials and our invention consists in an
improvement by which such travellers are rendered capable of being started with
greater ease than the travellers in ordinary use, when the machines in which they
are employed are put in motion and by which the passage of the yarns or threads
through the travellers without such yarns or threads becoming stained or soiled by
being brought into contact with the lubricated or greased rings with which the
travellers are employed is very greatly facilitated. The improvement in which our
invention consists is particularly beneficial in the case of travellers which are to be
applied to rings which have been in use for some time and still more particularly
beneficial in the case of travellers to be used in "wet doubling since the rings
become rough and even corroded in those parts upon which the traveller does not
bear when working.
"
In a traveller as ordinarily constructed for use in machinery or apparatus for
doubling cotton, wool, silk and other fibrous materials when the machine in which
each traveller is employed is put in motion the upper of the two extremities of the
metal forming the traveller is drawn into contact with the ring upon which it is
mounted and especially in cases in which the part of the ring against which the
extremity of the metal forming the upper portion of the traveller is drawn is
rough or corroded the roughness of the part against which the traveller is drawn
frequently causes the traveller to fly off the ring thus causing a waste both of
travellers and yarn. In order to more clearly indicate the evils which are over-
come by the improvement in which our invention consists we have in Fig. 1 of the
accompanying drawing illustrated a traveller (a) of the kind hitherto ordinarily
employed in doubling cotton, wool, silk and other fibrous materials as applied to a
ring (b). The traveller (a) is indicated in the position which it occupies at the
moment that the machine in which it is employed is put in motion at which moment
the extremity (a) of the metal forming the traveller (a) is drawn against the
surface () of the ring (a) by the tension of the yarn or thread passed around the
traveller (a). When the traveller (a) is fully in motion it does not bear upon
the part (6) of the ring (b) and consequently such part (¹) of the ring (b) not
being kept polished by the action of the traveller (a), becomes roughened especially
in cases in which "wet doubling" is carried on in which cases the portion (') of
the surface of the ring (b) even becomes corroded. When the machine in which
the ring (b) and traveller (a) are employed is put in motion the tension of the
yarn or thread passing through the traveller (a) drawing the extremity (a) of the
metal of which the traveller (a) is formed into contact with the part (61) of
the ring tends to prevent such traveller (a) from being set in motion around the
ring (6) and frequently by reason of the traveller (a) being unable to be drawn
around the ring (b) by the yarn or thread passed through such traveller (a) the
traveller (a) is caused to fly off the ring (b) and waste of yarn and loss of
travellers is occasioned and time is lost by reason of the spindle in conjunction
with which the ring (6) and the traveller (a) applied thereto are used being
rendered inoperative until a new traveller to replace the displaced one has been
placed upon the ring (6).

Our invention consists in an improvement by which the contact between the
travellers used in doubling cotton, wool, silk and other fibrous materials and the
rings to which such travellers are applied is reduced to a minimum and by which
it is rendered impossible for the upper of the two extremities of the metal of
which a traveller is formed to come into contact with the body of the ring to
which the said traveller is applied so that the liability of the traveller to be
thrown off the ring with which it is used is greatly reduced and a saving of
trouble of the material operated upon, and of travellers is effected. We form
the end of the upper portion of each traveller constructed according to our inven-
tion curved, bent or shaped in such a manner that the extremity of the metal
forming such portion of the said traveller can not by any possibility come into
contact with the body of the ring to which such traveller is applied while such
traveller is in use. The formation of a traveller in this manner not only obviates
the defects and disadvantages resulting from the extremity of the metal forming
the upper portion of a traveller, for doubling cotton, wool, silk, and other fibrous
materials as ordinarily constructed being capable of coming into contact with the
body of the ring to which it is applied but also renders it much more easy for
yarn or thread to be passed into the traveller without being brought into contact
with and soiled or stained by the ring or the lubricating material applied
thereto.
Fig. 2 is a vertical side view and Fig. 3 an end view of a traveller constructed
according to our invention. The part of the traveller (c) which is according to
our invention so curved, bent or shaped as to be incapable of coming into
contact with the body of the ring to which it is applied while such traveller is at
work is the part (c') which is shown as being curved so as to be concave on its
upper surface and convex on its lower surface. In Fig. 4 a traveller (c) con-
structed in accordance with our invention in the manner illustrated in Figs. 2
and 3. is shown as applied to a ring. From an inspection of Fig. 4 it is apparent
that the extremity (c) of the metal of which the traveller (c) is formed can never
come into contact with the part (1) of the ring (6) which may be rough or
corroded. As the extremity (c) of the traveller (c) can never come into contact
with the ring (b) the liability of such traveller (c) to be unshipped or thrown off
the ring (b) is very greatly reduced and a saving of trouble, material and
travellers is effected. In consequence of the part (c) of the traveller (c) being
curved upward much greater facility in comparison with the ordinary traveller
illustrated in Fig. 1 is afforded for the yarn with which the traveller is to be
used being passed into the traveller without being brought into contact with
and stained or soiled by the ring or the lubricating material applied thereto.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The hereinbefore described improvement in the construction of travellers for
use in machinery or apparatus for doubling cotton, wool, silk and other fibrous
materials which consists in forming each traveller with a part (c') bent shaped
or curved in the manner herein before described and illustrated in Fig. 2 of the
accompanying drawing so that the upper of the two extremities of the metal
forming such traveller can never come into contact with the ring to which it is
applied when being started or while it is at work and so that the passing of the
yarn into the traveller without such yarn being soiled or stained by coming into
contact with the ring or with the lubricating material applied thereto is
facilitated.
