Improvements in the Manufacture of Ring Travellers.
We, PETER EADIE, JOHN EADIE, PETER EADIE the Younger, and JOHN SCOTT
EADIE, all of Victoria Works, Paisley, in the County of Renfrew, Ring Traveller
Makers, do hereby declare the nature of this invention to be as follows:-
The increased speed at which yarn spinning and doubling by ring process is now
carried on adds materially to the tensile and centrifugal strain put upon the
traveller, and the object of this our invention is-
Without adding to the weight or bulk of the traveller to render the same
stronger in the line or direction of straining forces which arise from tensile strain
on the yarn and from centrifugal action.
According to this our invention whatever the bent form or outline of the
traveller may be, we make the said travellers of wire, the section of which, or a
portion of it, is round on its two surfaces radia to its rotation, its remaining portion
being flat so that the front portion of the traveller or that portion of the same that
is in contact with the ring is rounded and so is the back of the traveller, whilst its
sides are flattened, whereby the traveller is made stronger in the direction it is
subjected to greatest strain.
The improved travellers above referred to are of the class employed in the finer
counts of spinning and doubling.

Improvements in the Manufacture of Ring Travellers.
We, Peter Eadie, JOHN EADIE, PETER EADIE the Younger, and JOHN SCOTT
EADIE, all of Victoria Works, Paisley, in the County of Renfrew, Ring Traveller
Makers, 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 an improvement in ring travellers for spinning,
doubling, and like machines. .
The increased speed at which yarn spinning and doubling by the ring process
is now carried on adds materially to the tensile and centrifugal strain put upon
the traveller, and the object of the invention is without adding to the weight or
bulk of the traveller to render the same stronger in the line or direction of straining
forces which arise from the tensile strain on the yarn and from centrifugal action.
According to this invention whatever the bent form or outline of the traveller
may be, said travellers are made of wire, the section of which, or a portion of
which, is round on its two surfaces radia to its rotation, or it may be only round
on one surface its remaining portion being flat so that the front portion of the
D077

page_text: traveller or that portion of the same that is in contact with the ring is rounded, and
in one form so also is the back of the traveller, whilst its sides are flattened, whereby
it is made stronger in the direction in which it is subjected to the greatest strain.
The improved travellers above referred to are of the class employed in the finer
counts of spinning and doubling.
Such being the nature and object of our said invention, the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which:-
Fig. 1 is a cross section of a ring of a spinning frame on a large scale shewing
an improved traveller adapted for spinning in position thereon.
Fig. 2 is a plan of Fig. 1 with the traveller in section.
Fig. 3 is a section of part of a traveller shewing another form of same, on a
large scale.
Fig. 4 is a section of a ring of a doubling frame with a traveller adapted for
doubling in position thereon.
In Figs. 1 and 2 it will be seen that the traveller has two flat sides 1-1 while
the outside 2 and inside 3 of same respectively are rounded so that owing to the
narrowness of the section the surfaces in contact between the ring 4 and the
inside 3 of the traveller is reduced to a minimum, the point of contact or the rub-
bing surface being only that situated immediately upon the line A. B. Fig. 2.
The friction between the parts is consequently reduced to a minimum with the
result that a relatively heavier traveller can be used in the spinning or doubling of
relative counts or classes of yarn. both by reason of the lesser friction and the freer
movement or running of the traveller so made.
The heavier and stronger traveller possesses the further advantage in its com-
parative freedom from flying off the ring when the doffing is being performed and
likewise on starting the frame as whilst being light it is rigid enough to resist the
strain put upon it during doffing, and when starting or setting the frame on,"
and especially it is adapted and designed to withstand the strain put upon it by
the high running speed now common in the working of ring frames.
At least one size heavier or coarser of the improved travellers may be employed
in the spinning, or in the doubling of a given count or counts of yarn as compared
with the old form or section of traveller.
The traveller may be made with a flat outside edge or back 5 as shewn in Fig. 3,
but the section having the two rounded edges is the preferred form.
In Fig. 4 the section of traveller is the same as that shewn in Figs. 1 and 2.
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) A ring traveller for spinning and doubling frames having flattened sides and
a rounded inside edge, substantially as set forth.
(2) A ring traveller for spinning and doubling frames having flattened sides, a
rounded edge, and a flat back, substantially as herein described and illustrated by
the annexed drawings.
