Improvements in Rings and Travellers for Spinning Machines.
I, CHARLES HAMMOND POLAND, of Providence, in the County of Providence
and State of Rhode Island, United States of America, 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 :-
This invention relates to the rings and travellers for the same used on ring
spinning machines.
My said invention is illustrated in the accompanying drawing in which
Figure 1, is a top view of the ring and traveller, and the ring holder by which
the ring is held when in use.
Figure 2, shows a front elevation of the ring, traveller, and holder, with a part
of a cop of yarn.
Figure 3, is a vertical cross-section of the parts shown in Figure 2 with the part
of a cop in elevation.
Figure 4 represents in vertical cross-section a modification of the ring with part
of a cop of yarn in elevation, and
Figures 5 and 6, represent side views of the travellers used on the rings.
In its construction the ring B, is inade with straight vertical sides both inside
and outside, and a plain horizontal top and bottom square or nearly so to the sides
of the ring, making the upper half and the lower half of the ring just alike that
it may be reversed in the holder A, and used either side up with equal facility.
It has no thin edges to be worn into notches by the action of the traveller but
instead it has a wide bearing surface inside, outside and at the bottom for the
traveller to run on
The traveller a, as shown separately in Figure 5, has a long vertical inside
leg a', with a foot a, bent out at right angles to the leg, and a slightly curved top
with a straight vertical leg a¹ down the outside slightly curved out at the lower
end to facilitate the placing of the same on the ring. The outer leg is shortened
up enough to clear the flanges e, on the holder A.
The ring holder A, consists of a circular flat plate having a circular opening in
it nearly as large as the outside diameter of the ring B, and has two slight
flanges, e, e, turned up at right angles to the plate for a short distance on two
opposite sides of the opening between which the ring is pressed in, and held by the
contraction of the flanges.
Two holes or notches s, are made in the plate of holder to receive the screws to
fasten it to the ring rail. This traveller in operation starts quickly and runs
smoothly and uniformly owing to the proportionately great bearing it has ou the
surfaces of the ring and the distance between the foot under the ring and the top
where the yarn c, draws on the traveller. The centrifugal action of the traveller
in running throws the inner leg'a', against the inner face of the ring so as to touch
that surface its whole length and give it a great bearing surface which with the
wide bearing of the foot on the under side of the ring leaves little if any chance
for wear.
This ring and traveller effectually prevents what is called "ballooning"
of the yarn, and for which "separators are devised, in this way. When a bobbin
or cop a, is nearly full, which is the time when the "ballooning" takes place, the
size of the cop and its rapid motion produce a strong centrifugal current of air
that blows against the long inner leg of the traveller and presses it harder against
rn .

yarn that prevents it from flying out or "ballooning." This increase of friction
as the cop gets fuller is also very beneficial in another way, that is, in evening the
tension on the yarn by causing it to draw harder when the cop being nearly full is
drawing on the traveller in a direction nearly agreeing with the line of its motion
and therefore drawing it far more easily than it does when the cop is small and the
direction of the draft of the yarn on the traveller is more at an angle to the line
of the traveller's motion.
In Figure 4, a modification of the ring is shown that is made to accommodate
very light yarn by lessening the weight of the traveller which is done by shortening
the inside leg. It consists in making a plain narrow groove in the inner face of
the ring about half way down, so that the ring can be used either side up. The
traveller is the same as before described except that the inner leg is shortened, see
Figure 6, so as to bring the foot a³, into the groove r, see Figure 4, instead of
under the bottom of the ring. The full sized traveller of Figure 5, can still be
used on the ring the same as already described.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
.claim is:
1. A ring for ring spinning machines, having straight vertical inner and outer
faces, a flat top, and a flat bottom, square or nearly so to said sides, with means for
holding it on a ring rail, substantially as described.
2. A ring for ring spinning machines having a rectangular shape in vertical cross
section through its centre, in combination with means for holding it on a ring rail,
substantially as described.
3. A ring for ring spinning machines having a rectangular shape in vertical cross
section through its centre, and having a plain groove made around it in its inner
face, with means for holding it on the ring rail, substantially as described.
4. A traveller for ring spinning machines, having a straight inside leg, an outside
leg straight excepting a slight turn outward at its lower end, a rounding top, and a
flat foot on the lower end of the inner leg at right angles or nearly so to said leg,
substantially as described.
