Improvements in Rings and Travellers for use in Ring-spinning
Frames.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 :-
My invention has relation to rings and travellers employed in ring-spinning
frames; and it has for its object the provision of improvements which will greatly
lessen the amount of wastage in the breaking down of ends, resulting from worn-
out travellers slipping off the rings; greatly enhance the durability or life of the
traveller; lessen the necessary weight of the traveller; avoid the breakage of rings;
and enable the traveller to be more readily and quickly applied to the ring than the
same can be done with rings as commonly constructed.
In the practice of the art of ring spinning, prior to my invention, the traveller
has generally been applied to the ring by springing it over the flange of the latter;
and in the case of large rings and heavy travellers it necessitated a blow of a mallet
or other instrument upon the traveller in order to spring it over the flange.
This mode of applying the traveller to the ring rendered it necessary that the
steel out of which the traveller was made, should be quite soft, so as that it should
have high resilient properties, as otherwise it could not be sprung, and given the
desired bearing, upon the flange of the ring.
The necessarily soft character of the traveller rendered it susceptible of rapid
wear and made it short lived, so that in use it soon became so worn as to be pulled
or slip from the flange of the ring with the result of breaking down ends and causing
serious wastage.
In cases where the traveller was sprung upon the ring by the blow of a mallet,
not infrequently happened that the ring was broken. In cases where it has been
proposed to construct the ring or the traveller as that the latter might be easily
applied to the ring, it has been found to invariably pull off with greater frequency
than where sprung upon the ring, thus aggravating the mischief or damage resulting
from travellers leaving their rings.
By my improvement, the objections mentioned are entirely overcome, and several
important advantages are gained, the said improvement consisting in cutting away
or reducing the ring at a suitable point in the circumference of the ring, either in
the neck or vertical wall of the ring, or in the edge or base of the flange, just
sufficient to allow the traveller to be placed upon the ring at such point, without
appreciably spreading the traveller, and to become locked upon the ring after
passing in either direction beyond such point, all as will more fully appear
hereinafter.
Reference is to be had to the annexed drawing and to the letters marked
thereon, forming a part of this Specification, the same letters designating the
same parts or features, as the case may be, wherever they occur.
Of the drawings :
Figure 1, is a perspective view of a spinning ring and traveller showing my
improvement.
Figure 2. is a vertical central sectional view of a reversible ring held in a

page_text: ring holder, illustrating the mode of applying a traveller to a ring constructed
in accordance with my invention.
Figure 3, is a sectional view through a ring, showing the position of the
traveller with respect to the ring in the operation of spinning.
Figure 4, is a plan view of a modified form of the invention.
In the drawings:
a designates a spinning ring, provided with the usual flanges or lips b.
c is the traveller which may be of the ordinary loop form, the ends d projecting
inward on a substantially straight line, so as to afford a bearing of sufficient extent
on the under surface of the lips b.
e designates a point where the ring is reduced or cut away to an extent sufficient
to permit the traveller to be placed over the flange of the ring without springing or
spreading the ends apart, as is indicated in Figure 1, and at the right in Figure 2.
In Figures 1 and 2, the reduced point is shown as a groove made in the neck of
the ring directly below the outside lip, while in Figure 4, it is shown as formed by
cutting away a portion of the outer lip. Either of these forms, or any other suited
to the purpose will fall within the scope of my invention, the essential feature of
which is the reduction of the ring at a suitable point where it will not interfere
with the operation of the traveller, so that the latter may be applied to the ring
without spreading or opening the same or springing it thereover, and so that after
the traveller passes this reduced point in either direction, it will become locked
upon the ring and cannot be removed without being considerably spread.
By this means I am enabled to make travellers of the greatest hardness, so as to
be capable to a maximum extent of resisting wear, and without any liability of
breaking them, or the ring in their application to the latter.
By enhancing the wearing properties of the traveller, I am enabled to effect a
substantial saving not only in rings and travellers themselves, but in wastage,
resulting from the breaking down of ends by reason of worn out travellers slipping
from their rings.
I am furthermore enabled to make travellers of other material than metal, such,
for example, as glass, and other vitreous and very hard substances, reducing the
friction and wear of both the traveller and the ring.
It will be understood that my invention contemplates the reduction or cutting
away
of the ring at a point in its circumference, so as to permit the traveller to be
applied at such point, the ring being enlarged in its circumference beyond such
point, so that the traveller becomes locked after it passes in either direction beyond
such point.
With this construction, in addition to what has already been said, the full
strength of the ring is preserved, and there is no liability of the traveller pulling
off or leaving the ring, as would be the case if the ring were reduced throughout
its circumference.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :
1. A spinning ring, having a point in its circumference at which it is reduced or
cut away to permit the traveller to be applied without spreading, the ring beyond
such reduced or cut away point being of normal or enlarged size, whereby the
traveller may become locked on the ring after passing the reduced point, as set
forth.
