Improvements in the Construction of Rings and Travellers Employed
in Ring-spinning and Ring-doubling Frames for Spinning and
Doubling Cotton and other Fibrous Substances.
We, JOHN HARGREAVES of 368 Derby Street, Spinning Overlooker, and EDWARD
GILLOW of 2 Raby Street, Foreman Mechanic, both of Bolton in the County of
Lancaster, do hereby declare the nature of our said invention to be as follows:-
-
This invention relates to improvements in the construction of rings and travellers
employed in ring-spinning and ring-doubling frames for spinning and doubling
cotton, and other fibrous materials and consists in arrangements of rings and
travellers better adapted than those in use hitherto. Our improved rings are
constructed with flanges of any suitable form, such as, perpendicular, concaved,
angular, grooved or others; the bearing parts on which our improved faller
traveller operates-being of such a form as to reduce the friction of the traveller
to a minimum when thrown against the bearing parts by the centrifugal force of
the same.
These improved rings are made of the usual materials, and are mounted
in any suitable. manner in or on a copping rail operated in the usual manner.
Our improved faller traveller is composed of one or two horizontal bars with
one or more projections, angular or otherwise, at one end, to fit between or on
the flanges of the ring. The horizontal bars are connected in any convenient
manner and place by any number of uprights. This faller traveller is constructed
with an upright bar, curl, or projection placed in any position from the centre
of the spindle to the inner diameter of the ring on the leading side of the spindle;
and can be employed for operating either weft ог twist" by simply reversing
the same.
The traveller is so constructed as to ensure of the same being carried
round even at the commencement of the formation of the cop and when winding
on the bare spindle, and swivels in a radial direction to and from the cop-spindle,
or tube mounted thereon, and comes in contact with the said cop-spindle, or tube,
in such a manner as to cause the spindle to act as a fulcrum to the traveller, thus
giving the yarn by which it is driven a greater power when working on the cop nose.
The chief feature of this faller traveller is that the yarn only requires once
threading, this being effected by the yarn being delivered inside the upright bar,
curl, or projection and next to the spindle. In all other travellers employed for
spinning and doubling the face of the traveller is between the spindle and the
yarn being delivered, that is, the face of the traveller is next to the spindle and
the yarn outside.

DESCRIPTION OF DRAWINGS.
Figs. 1, 3, 4, 5, 6, 7, 8, 9, 12, 13, 14, and 15 are side elevations of various
modifications of our improved faller traveller, wherein the yarn is threaded twice,
mounted on rings such as are employed in ring-spinning and ring-doubling
frames for spinning and doubling cotton and other fibrous substances-Fig. 2 is
a plan of Fig. 1, and Figs. 10 and 11 are side elevations of our improved faller
traveller wherein the yarn is threaded only once.
In all the figures the same letters are employed to indicate corresponding parts.
The rings A are made of the usual materials; the hearing parts B, on which our
improved faller travellers operate, being of the form shown to reduce the friction of
the travellers to a minimum when thrown against the bearing parts B. and B¹
by the centrifugal force of the same. To further reduce friction and ensure
of our improved faller traveller working accurately and to prevent contact with
the plate D we provide the rings A with the bearing surfaces B¹ as shown in
Figs. 12, 13, 14, and 15. The rings A are provided with the flanges D, by which
they are attached to the copping rail; the latter being operated in the usual
manner. The faller travellers are composed of the horizontal bars E with the
projections G at one end to fit on the bearing parts B of the rings A. The hori-
zontal bars E are connected together by one or more uprights H, to which are
attached the bars, curls, or projections I, as in Figs. 1 to 15 inclusive, for guiding
the yarn to the spindle, cop, or tube K, and can be employed for operating either
"weft" or
twist" by simply reversing the travellers on the rings A. The latter
can be constructed with the annular chamber O, in which case the faller traveller
is provided with the centre horizontal bar E as shown in Figs. 6, 7, 8, 9, 12, and 13.
The construction of our improved faller traveller ensures of the same being
"

page_text: carried round at the commencement of the formation of a cop and when winding
on a bare spindle. This faller traveller swivels on the bearings B and B₁ of the
rings A in a radial direction to and from the spindle, cop, or tube K, and comes
in contact with the latter in such a manner as to cause the spindle to act as a
fulcrum to the said traveller, thus giving the yarn M, by which it is driven, a
much greater power when working on the cop nose.
"
Our improved faller traveller is carried round the ring A by the yarn from the
spindle, cop, or tube K mounted thereon, in the direction the latter is travelling,
which, with the centrifugal force, reduces the "drag on the yarn considerably,
thus enabling various counts of yarn to be spun or doubled with less twist than
hitherto.
This faller traveller reduces the distance from the point at which it receives the
yarn from the delivery rollers to the point at which it delivers it on to the
spindle, cop, or tube K, by which a reduced "drag" on the yarn is effected,
enabling finer or softer yarns to be spun or doubled than hitherto.
By passing or delivering the yarn M between the upright H and the spindle,
cop, or tube K it is conducted direct, thus reducing leverage to the least possible
amount. The yarn M is conveyed to the spindle, cop, or tube K by threading it
once in the faller traveller, as in Figs. 10 and 11, wherein it passes under the
bar, curl, or projection I and delivers the yarn between the bar, curl, or pro-
jection I and the spindle, cop, or tube K.
When threading the yarn M twice on the faller traveller, it is conveyed from
the ordinary delivery rollers under the top bar E at a point nearest to the
delivery rollers, and over the horizontal bar E, then between the upright bar,
curl, or projection I and the spindle, cop, or tube K as shown in Figs. 1, 3, 4, 5, 6, 7,
8, 9, 12, 13, 14, and 15. Our improved faller traveller and its attachments are
equally applicable for operating upon either "twist” or “weft" yarns.
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. Providing the rings A with the projecting flat surfaces B₁ to prevent the
traveller mounted thereon coming in contact with the carrying plate D to
minimise friction, substantially as described and as shown on the drawings.
2. In ring-spinning and ring-doubling frames delivering yarn on a spindle,
cop, or tube between the inside of the bar, curl, or projection I on the traveller
and the spindle, cop, or tube receiving the yarn, substantially as described for
the purpose specified.
3. In a faller traveller employed in ring-spinning and ring-doubling frames the
combination of the horizontal bars E, uprights H, and the bar, curl, or projec-
tion I, the latter being disposed at any point between the centre of the spindle K
or its equivalent and the ring A on the delivery side of the spindle or its equiva-
lent, for the purpose of delivering the yarn inside the bar, curl, or projection I
next to the spindle, cop, or tube, substantially as described and shown.
4. In ring-spinning and ring-doubling frames delivering yarn on a cop, spindle,
or tube from the delivery rollers under and over the horizontal bar E, and between
the bar, curl, or projection I and the spindle, cop, or tube, substantially as described
and as shown on the drawings.
5. The respective combinations and constructions of our improved faller traveller,
substantially as described and shown on the drawings, or other combinations of
the component parts.
