I, WILLIAM CLARK, of the firm of A. M. and Wm. Clark, of 53, Chancery
Lane, in the County of Middlesex, Fellow of the Institute of Patent Agents,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
RINGS AND TRAVELLERS OF RING AND TRAVELLER SPINNING FRAMES & commu-
"
nication to me from abroad by Jean Jacques Bourcart of Zurich Switzerland
Engineer to be as follows:-
This Invention relates to improvements in rings and travellers of rings and
traveller spinning frames forming the subject of previous patents N° 870 of 1879
N° 5029 of 1880 and 4241 of 1884.
The improvement consists in the addition to an ordinary traveller of a shank
which supports the yarn up to the bobbin and presents the jamming of the
traveller upon the ring.
In the accompanying drawing figure 1 represents an ordinary traveller a being
the ring rail, 6 section of ring, c traveller, d hook and f yarn.
Figure 2 represents the improved traveller, a being the ring rail, 6 section of
ring, c traveller e shank or arm, g bend, h guide f yarn and n end of shank.
The traveller is composed of the parts h, c, g to which is added a shank or
extension of straight or curved form h n. The guiding end h of the traveller
may run either in a groove or upon a ring; the part 9 prevents the traveller from
dropping and may rest either upon an edge, flange or flat surface; the end n rests
upon the upper edge of the ring and may be of hooked or curved form; the
portion c, e, may also be of any desired form. In this manner, the part g of the
traveller (the yarn f pulling in the direction 2) will not press against ring b but
the part n of said traveller will press against the ring in lieu of g.
In the ordinary form of traveller employed for twisting, shown in figure 1, the
yarn f pulls the traveller in the direction x pressing hook d and also part h
against ring 6 and owing to the great leverage, the traveller becomes jammed and
will not slide around the ring, which is a great objection. In the improved
traveller of this invention, the yarn f is passed under n and then again under g,

page_text: which may be provided with a hook or otherwise formed so as to pass the yarn
through it a third time. In this manner the tension of the yarn, tends to draw
the part h of the traveller c in an upward direction against b and inversely presses
the end n in a downward or inclined direction against the upper edge of ring b;
all liability of the traveller to jam in the ring is thus rendered impossible, the
traveller freely following the motion of the bobbin as it is drawn by the yarn. It
is evident that if the hook d figure 1 or its equivalent be retained, the shank a
figure 2, should be such as to prevent d from bearing against the outer edge of
ring b.
The form of traveller shown in figure 2 is simply intended to admit of its being
applied against the interior of the ring, when when winding on the large diameter
of the bobbin.
By making a traveller of the form shown in figure 1 and curving the shank e
the same result may be attained, only in this case the shank should terminate in
a small hook at n.
Instead of a ring 6 mounted in a ring rail a as shown, the ring rail itself
might be provided with a groove on its underside, the action of the traveller
being the same.

I, WILLIAM CLARK, of the firm of A. M. and Wm. Clark, of 53, Chancery Lane,
in the County of Middlesex, Fellow of the Institute of Patent Agents, do hereby
declare the nature of this Invention (a communication to me from abroad by Jean
Jacques Bourcart of Zurich Switzerland Engineer 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 rings and travellers of ring and
traveller spinning frames forming the subject of previous Patents N° 870 of 1879,
N° 5029 of 1880, and N° 4241 of 1884.
The improvement consists in the addition to an ordinary traveller of an arm so
arranged and applied as to support the yarn up to the bobbin and prevent the
nipping of the traveller upon the ring.
In the accompanying drawings, figure 1. represents an ordinary traveller, a being
the ring rail b the ring in section c the traveller and f the yarn. Figure 2 repre-
sents the improved traveller, a being the ring rail, 6 the ring, o the traveller, e the
arm, and f the yarn.
The traveller has the bent or hooked ends g h embracing the ring and an arm
or extensions of straight or curved form. The guiding end h of the arm may run
either in a groove or upon the ring, the elbow or bend g prevents the traveller
from dropping and may rest either upon an edge or on a flange or flat surface;
the end n rests upon the upper edge of the ring and may be of hooked or curved
form; the portion o, e may also be of any desired form. The effect of this con-
struction is that the resultant of the pull of the yarn f being in the direction x
the part g of the traveller will not press against ring b but the part n will press
against the ring in lieu of g. In the ordinary form of traveller employed for
doubling and twisting shown in figure 1 the yarn f pulls the traveller in the
direction thereby pressing hook d and h against the ring, the result being that
the traveller is liable to seize on the ring so as no longer to slide around it which
is a great objection. In the improved traveller of this Invention, the yarn fis
passed under n and then again under g which may be provided with a hook or
otherwise formed so as to pass the yarn through it a third time. In this manner,
the tension of the yarn tends to draw the part h of the traveller c upwards against b
and to press the end n downwards or in an inclined direction against the upper
edge of ring b. All liability of the traveller to jam in the ring is thus rendered
impossible, the traveller under the pull of the thread, freely following the motion
of the bobbin and the arm e acting as a lever to free h from the ring. It is evident
that if the hook d (figure 1) or its equivalent be retained the shank a figure 2
should be so arranged as to prevent d from bearing against the outer edge of
ring b.
The angular form of traveller shown in figure 2 is designed to admit of the
traveller lying close against the interior of the ring when winding on the large
diameter of the bobbin. By making a traveller of the form shown in figure 1 and
curving the arm e the same result may be attained, only in this case the arm

page_text: should terminate in a small hook at n.
Instead of a ring b mounted in a ring
rail a as shown, the ring rail itself might be provided with a groove on its under-
side, the action of the traveller being the same.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed; I declare that
what I claim is ;-
A traveller c for ring spinning machines provided with an arm e substantially
as herein specified, said arm being so arranged and operating as to prevent part g
from jamming upon the ring b, the part h guiding the traveller around the ring as
herein before described, whatever may be the form of the ring 6 traveller c and
arm e.
