"Improvements in and relating to Ring Spinning and Doubling
Machinery."
We JAMES BUCKLEY of 51 Mount Pleasant, Liverpool, in the County of Lancaster,
Retired Cotton Mill Manager, JOHN HENRY BUCKLEY of 34 Miry Lane, Chew Moor,
near Bolton, in the aforesaid County, Cotton Mill Manager, and ELIJAH ASHWORTH,
of Moss Brook Works, Collyhurst, Manchester, also in the County of Lancaster, Card
and Machine Maker, do hereby declare the nature of this invention to be as
follows.
Our said Invention relates to the rings and travellers of ring spinning and
doubling machinery and especially to the type of ring traveller consisting of a curved
bar with a fork at each end and sometimes known as a flyer traveller.
In using these double fork travellers it has been found that as at present made
they have a great tendency to vibrate and shift their position when running and to
cant in the ring in such a manner that the under member of each forked end
becomes worn and cut. This unsteadiness and wearing of the travellers not only
militates against the production of perfect yarn but also sets up an amount of friction
and drag which is a frequent source of breakage of yarn besides absorbing power and
leading to the destruction of the traveller itself. As at present made these travellers
have the curved back bone or bar between the forked ends in the middle of the
traveller, that is to say equidistant between the members of the fork. By careful
experiment we have ascertained that the working of the traveller is much improved
by placing the said curved back bone or bar more or less to one side, that is to say to
the lower side of the traveller as it appears when carried in the ring. This preponder-
ance of weight to the lower side seems to have the effect of steadying the traveller and
causing it to run without the objectional vibrating and canting at present
experienced.
The wearing and cutting of the traveller forks is got rid of and the traveller runs
sweetly and without any of the frictional drag heretofore experienced. We thus save
power, prolong the life of the traveller and produce better work.
In conjunction with the said improved traveller we use a ring of an improved form.
Instead of having a ring with a straight face in the internal circumference, we make
the said circumferential face considerably curved or rounded in section. In combina-
tion with our improved form of traveller we find that the said altered form of ring
secures easy running and an absence from wear and drag which materially advances
the utility of our invention.

page_text: The objectionable wearing and cutting of the traveller is obviated and the traveller
runs sweetly and without any of the frictional drag heretofore experienced by the
canting of the traveller, thus saving power, prolonging the life of the traveller and
producing better work.
By experiment we find that the wearing of our improved traveller by frictional
contact with the ring occurs chiefly at the back of the curved back-bone at the
point marked a and upon the top of the lower forks marked b. This will be more
apparent from an inspection of Fig. 4. As the improved form of traveller does not
cant and vibrate but is maintained upright and steady, the curved back-bone of the
traveller, flying outwards by centrifugal force, bears upon the interior surface of the
ring and thus takes the frictional drag chiefly at that point.
In conjunction with the said improved traveller we use a ring of the form shown
in the sectional view Fig. 3.
The ring c is formed on the interior periphery with a curved or rounded surface as
shown in the section.
In combination with our improved form of traveller we find that the said curved
or rounded inner surface secures easy running and reduced wear and drag which
materially advances the utility of our invention.
We are aware that rings with slightly rounded interior peripheries have been
before used, and we make no claim to such a ring per se but only when used in
combination with our improved travellers..
We have indicated in the sectional view Fig. 3 the extent of rounded surface
which we have found to be most suitable for the purposes of our invention.
The interior surface of the ring is lubricated in any suitable or convenient manner.
For instance we might drill or otherwise form a small hole d in the thickness of the
ring and conduct through the same a minute quantity of oil or other lubricant to
ensure the easy running of the traveller.
Having now particularly described and ascertained the nature of our said
invention and in what manuer the same is to be performed we declare that what
we claim is.
1) In travellers of the indicated nature for ring spinning and doubling frames,
placing the back-bone or bar connecting the forked ends of the traveller, below the
centre of the forks for the purposes and substantially as described and illustrated.
2) The combination with a traveller constructed in accordance with claim 1, of a
ring formed with a curved or rounded interior periphery substantially as described
and shown
