Improvements in Apparatus Used for Spinning and Doubling Cotton
and other Fibrous Substances.
I JAMES SEED of 4 Avenham Terrace Preston in the County of Lancaster Engineer
do hereby declare the nature of this invention to be as follows:-
.
This invention relates to improvements in ring frames, and method of lubricating
rings of ring spinning and doubling frames, and improvement in travellers which are
used on such ring frames.
The object of the invention is to enable yarn, or thread to be spun or doubled on the
bare spindle, paper tube, or bobbin with greater facility than hitherto.
It has formerly been considered that in ring frames the spindle must always be
mounted and revolve in a vertical position.
One of my improvements in ring frames consists in setting the spindles and rings
in an inclined position so that a line drawn through the longitudinal axis of the spindle
and continued upwards will pass direct to the "nip" of the rollers, or more nearly so
(according to the amount of inclination given to the spindles), than when they are in
the ordinary vertical position, the rings being set in a plane at right angles to the axis
of the spindles.
By this improvement the deflection of the yarn, or thread passing over or through
the guide eye may be nil, or very little; this allows the twist to run up to the rollers
with no obstruction, or very little, from the guide eye, and more or less direct to the
"nip" of the rollers according to the amount of inclination given to the spindles, and
the inclination of the rollers, and by this arrangement the yarn or thread is made
equally strong throughout the length between the travellers and the rollers.
When the ordinary traveller with the yarn passing once under it has been used for
spinning on the bare spindle, or on small diameters the yarn passes through the traveller
at a higher part than when spinning on larger diameters which causes the outside foot
of the traveller to be brought against the under part of the outside flange of the ring,
or to vibrate up or down; thus the surface of the ring becomes rough, and this pro-
duces a great increase of friction between the ring and traveller, which causes the
yarn or thread to break.

page_text: The improved traveller is constructed from steel wire or other suitable material, and
consists according to one modification of a single piece of wire spanning the ring, bent
in such a form that the part placed on the inside of the ring is composed of a small
curve, or two straight parts joined by a curved, or straight part to a larger curve
forming the part on the outside of the ring; by this form the yarn or thread passing
once under the traveller is prevented from changing its position in the traveller
whether spinning at the small or large diameters of the cop or bobbin ; the position of
the yarn or thread leaving the traveller being about level with or a little above the top
of the ring; the outside foot of the traveller assumes a position below the outside
flange of the ring, and does not materially change its position except on starting or
stopping the ring frame.
Various modifications of form of the improved traveller can be made in all of which
the yarn, or thread cannot change its position in the traveller, or cause the outside foot
to be brought in contact with the outside flange of the ring when spinning.
Another of the improvements consists in an apparatus for lubricating rings of ring
frames whether spinning or at rest by means of a spray of lubricant produced by a
forced curront of air.
The apparatus may be arranged to lubricate the rings automatically.

I JAMES SEED of 4 Avenham Terrace Preston in the County of Lancaster
Engineer 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 relates to improvements in ring frames, and improvements in
"travellers" which are used on ring frames for spinning and doubling.
The object of the invention is to enable yarn, or thread, to be spun or doubled
on the bare spindle, paper tube, or bobbin with greater facility than hitherto.
In carrying out my invention I prefer to set the spindles and rings in an inclined
position so that a line drawn through the longitudinal axis of the spindle and
continued upwards will pass direct to the "nip" of the rollers or more nearly so
(according to the amount of inclination given to the spindles) than when they are
in the ordinary vertical position, the rings being set in a plane at right angles to the
axis of the spindles.
By these means the deflection of the yarn or thread passing over or through the
guide eye may be nil or very little; this allows the twist to run up to the roller with
no obstruction, or very little from the guide eye, and more or less direct to the
nip of the rollers according to the amount of inclination given to the spindles,
and the inclination of the rollers, and by this arrangement the yarn or thread is
made equally strong throughout the length between the travellers and the rollers.
When the ordinary traveller with the yarn passing once under it has been used
for spinning on the bare spindle, or on small diameters the yarn passes through the
traveller at a higher part than when spinning on larger diameters which causes the
outside foot of the traveller to be brought against the under part of the outside
flange of the ring, or to vibrate up or down; thus the surface of the ring becomes
rough and this produces a great increase of friction between the ring and the traveller,
which causes the yarn or thread to break.
The improved traveller is constructed from steel wire or other suitable material and
consists according to one modification of a single piece of wire spanning the ring,
bent in such a form that the part placed on the inside of the ring is composed of a
small curve, or two straight parts joined by a curved or straight part to a larger
curve forming the part on the outside of the ring; by this form the yarn or thread
passing once under the traveller is prevented from changing its position in the
traveller whether spinning at the small or large diameters of the cop bobbin, or
tube, the position of the yarn or thread leaving the traveller being about level with or
a little above the top of the ring; the outside foot of the traveller assumes a position
below the outside flange of the ring, and does not materially change its position except
on starting or stopping the ring frame.
In order that my invention may be clearly understood I have annexed hereunto a
sheet of drawings and have marked the same with figures and letters of reference
corresponding with those in the following explanation thereof.
The Figs. 1. 2. 3. 4. 5 in the annexed drawings show side elevation view of the
improved travellers; the same letters in the Figs. refer to the corresponding parts in
the various travellers.
a, b is the outside foot, c the point where the yarn passes through the traveller,

page_text: c, d the part to prevent the yarn or thread from slipping from the point c; d, e, f the
outer part of the traveller; and -g the outer foot.
Fig. 5 shows a traveller which can be put on the ring either way about.
Fig. 6. shows part of a ring in section, j is the inner flange, and & the outer, having
a traveller on it in the position it assumes when spinning at the nose of the cop 1;
1, i represents the yarn passing through the traveller at the point c.
When spinning
at the larger diameters the upper part of the traveller leans forward, the outside foot
varying very little from the position shown.
Fig. 7. shows a section of a ring and side elevation of an ordinary traveller in the
position it assumes when spinning on a small diameter, and m, n the yarn passing
through the traveller, it having slipped up from the part marked o to the position
shown as the ring rail moved from the larger to the smaller diameter of the cop,
the outside foot p being pulled up against the under side of the outside flange k of
the ring.
I have shown this Fig. in order that comparison may be made with my improved
traveller shown in Fig. 6. working at a similar situation is. the nose of the cop.
In Fig. 7. the outside foot of the traveller is pulled up against the under side of the
outside flange, in Fig. 6 it is clear of the same; again in Fig. 7. the position of the
yarn coming from the roller meeting the traveller at a point further from the spindle
than the inner edge of the ring, together with the leverage of the yarn leaving the
traveller along the line n above the edge of the ring and above the centre of gyration
of the traveller combine to raise the outside foot into the position shown thereby
causing additional friction; whereas in Fig. 6 the upward pull of the yarn coming
from the roller in the position shown has a tendency to depress the outer foot, the
pull of the yarn along i at a position a little above the ring, and the centre of
gyration of the traveller has the opposite tendency and therefore these two counter-
balancing forces help to maintain the outside foot approximately in the position as
shown in Fig. 6
Various modifications of form of the improved traveller can be made so long as the
said form is such that yarn or thread cannot change its position in the traveller, or
cause the outside foot to be brought in contact with the outside flange of the ring
when spinning as above described.
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
First. A single span traveller made from steel wire, or other suitable material so
constructed that the yarn or thread on being placed once under the traveller passes
automatically to, and continues to pass at one definite position; which position does
not change with the varying tensions resulting from the larger, or smaller diameters
of the chase when spinning on the cop, bobbin, or tube; such definite place being so
situated in the traveller as also to maintain the outer foot in a position which does
not materially vary and does not allow the outer foot to be brought in contact with
the outer flange of the ring during the operation of spinning or doubling substantially
as shown and described.
Secondly. The ring frame having inclined spindles when used in combination
with the improved form of traveller.
Thirdly. The improved travellers
