Improvements in Travellers for Spinning Fibres and the like.
I, ARTHUR WILSON METCALFE, of Castle Stead, Pateley Bridge, in the County
of York, Flax Spinner, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has for its object the construction of travellers used in conjunction
with rings for the spinning of fibres and the like, in such a manner that, the traveller
gives an elasticity to the yarn during the operation of spinning, by which it is made
Sinoother, has fewer piecings, and is built on to all portions of the bobbins with more
uniformity in the drag, than is the case when travellers of the ordinary construction
are used.
I accomplish my object in the following manner. The rings may be of the
ordinary construction attached to the ringrail in the usual manner. but the eye of
the traveller under which the yarn passes for guiding it on to the bobbin, is con-
siderably above the top flange of the ring, is bent to freely embrace the flange of
the ring and also at right angles to the vertical portion of the traveller, by which it
is guided in its circuit, the drag of the yarn controlling the vertical portion of the
traveller, thus giving an elastic and more equal drag, by which the yarn is made
smoother, is not so subject to uneven tension and thereby frequent breakages, as is
the case with travellers of the ordinary construction when operating upon unelastic
fibres such as flax.

Improvements in Travellers for Spinning Fibres and the like.
I ARTHUR WILSON METCALFE of Castle Stead, Pateley Bridge, in the County
of York Flax Spinner 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 has for its object the construction of travellers used in conjunction
with rings for the spinning of fibres and the like in such a manner, that the
traveller gives an elasticity to the "drag" on the yarn during the operation of
spinning by which it is made smoother, has fewer piecings and is built on to all
portions of the bobbins with more uniformity in the drag than is the case when
travellers of the ordinary construction are used.
I accomplish my object in the following manner. The rings may be of the ordinary
construction attached to the "ringrail" in the usual manner but the eye of the
traveller under which the yarn passes for guiding it on to the bobbin is considerably
above the top flange of the ring and is bent to freely embrace the flange of the ring
and also at right angles to the vertical portion of the traveller by which it is guided
in its circuit the "drag" of the yarn controlling the vertical portion of the traveller
thus gives an elastic and more equal "drag" by which the yarn is made smoother,
is not so subject to uneven tension and thereby frequent breakages as is the
case with travellers of the ordinary construction when operating upon nonelastic
fibres such as flax.
Such being the nature and object of my said invention the following is a

Figs. 7. 8. 9 are different views of the improved "traveller" shewn by
Fig. 1 and 2 and drawn to enlarged scale in order to clearly illustrate their
configuration.
Figs. 10. 11. 12 are different views of the improved "traveller” shewn by Figs. 3
and and drawn to enlarged scale.
Figs. 13. 14. 15 are different views of the improved "traveller" shown by Figs. 5
and 6 and drawn to enlarged scale.
According to this my said invention the rings 1. are preferably of ordinary con-
struction having a single flange 2. or the double flanged ring may be employed, and
such rings 1, are attached to the ring rail 3 in the usual and well known manner.
The traveller 4 is made of brass or steel wire, bent to the form shown by the
drawings the eye 5 of the traveller 4 being considerably above the top of the
flange 2 of the ring 1. and the lower part of the wire forming the traveller 4 is bent
at or nearly at right angles to the vertical position so forming the legs 6. 6 which
lie to and Inosely enclose the narrow portion of the ring 1 below the flange 2 the
yarn passes through the eye control the vortical portion of the traveller and
admits of vertical and radial movement that is to say the eye of the traveller can
move to or further from the bobbin, in that way the traveller assumes a working
position best adapted to requirements and contingencies whereby lumps or enlarge
ments on the yarn pass through the eye of the traveller without undue strain and
jerks reducing breakage of yarn to a minimum and a nearer approach to uniformity
of drag is obtained whereas with travellers as heretofore constructed the yarn being
spun had practically no control over the position of the traveller, the latter, in
practical use, flying out through centrifugal action to the utmost extent, and so long
as working remaining in that position and in order to obtain sufficient drag with
ordinary travellers, the wire employed was necessarily very thick and when used in
the round state was very diflicult to spring over the flange of the ring 1 and when
used in the flattened state considerable friction was opposed to the free passage of
the yarn. These defects are remedied in my improved form of traveller as the
length of the eye makes the traveller much easier to "spring" over and on to the
ring it also greatly facilitates adjustment of the drag by the gunge of wire
employed height of loop 5 and length of leg or legs 6 as I have found in practice,
that in order to obtain the same amount of drag with my improved traveller as with
the traveller as heretofore employed a greater actual weight of wire is used thereby
showing that the "drag" of the new traveller depends more upon its dead weight
and consequently less upon friction between the traveller 4 and the ring las
heretofore.
By having a larger loop or oye 5 and by reason of the traveller changing when
necessary its vertical and radial position lumps or knots in the yarn are allowed to
pass without sticking and breaking down "the ends."
The annexed drawings hereto illustrate three forms of travellers which I have
found give good practical results, but I would have it understood that I do not confine
nor limit myself to the use of traveller of the precise configuration shewn as it is

page_text: obvious the same may be varied in shape without departing from my invention so
long as it is provided that the vertical and radial working position of the traveller
is controlled by the yarn by reason of length or height of the loop or eye whereby
the eye, or working part of the traveller adapts itself to varying conditions as
explained and its tendency to outward or contrifugal action is controlled by the yarn
passing through the loop or eye at the highest part, and that the traveller have one
or more legs such as 6 which embrace the ring giving the traveller steadiness to the
upright position of the traveller affording increased bearing surface on the ring and
consequent durability.
The form of traveller as described and illustrated is useful for ring spinning and
twisting generally but is specially, valuable for strong and rigid fibres such as flax
(wet or dry spinning) and when used for wet spinning of flax the traveller should
be made of brass as I have found in practice that for wet spinning brass is more
durable than steel.
In rings of say 24" inches diameter for spinning flax yarns of say 14 S to 18 $
counts wire of about 13 B.W.G. guage is suitable.
The drag on any count or kind of yarn or twist may readily be adjusted to usual
or special requirements by varying the guage of wire the height of loop and length
of leg or legs of the traveller.
Having now particularly described and ascertained the nature and object of my
said invention I would have it understood that what I claim is.
I claim the improvements in travellers wherein is employed a raised elongated
eye or loop and legs such as 6 whereby the traveller is enabled to readily change
and adapt its vertical and radial working position in relation to the bobbin and
ring for purposes herein set forth and substantially as illustrated by drawings
annexed.
