PROVISIONAL SPECIFICATION left by the said William Edward
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 28th January 1873.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lanc, in the County of Middlesex, Civil Engineer, do hereby declaro
the nature of the said Invention for "IMPROVEMENTS IN SPINNING
MACHINERY," to be as follows:-
:-
This Invention relates to the ring and traveller used in spinning
machinery in which a transverse bar is so combined with the ring and
spindle of the ring frame as to rotate freely within the ring and in
contact with the spindle or the yarn thereon for the purpose of causing

page_text: the yarn to pass to the spindle at an uniform angle and consequently at
an uniform tension to avoid breakage of the yarn in starting the spindle
and material variations in the size of it. These are the general objects
of the Invention, but one of the moro particular objects of it is to so
adjust the dimensions and conformation of the ring and shape of the
traveller as to admit of running the spindle at the highest rate of speed,
and so that a bobbin or cop may be made nearly or quite as large in
circumference as the inner circlo of the ring with the traveller as short,
and the diameter of the ring as small as practicable to obtain these ends.
A light and delicate, or heavy and strong, but equally even tension will
also be at command in the same ring by changing the size of the
traveller; likewise facility and economy in the construction of the parts
and in their current use and repairs are obtained.
The Invention consists in a novel construction of the annular shell or
cap, which is mounted upon or made to form a part of the ring by pro-
viding the inner and under side of the cap with a bead or annular
projection of any desired shape in its transverse section, so that in all
positions of the transverse bar or traveller the shell or cap shall afford an
uniform bearing at the points of contact, thereby producing an uniformn
friction and tension upon the thread.
Furthermore the Invention consists in a transverse bar or traveller
with straight or nearly straight ends in line with each other, but with
its centre portion curved in a lateral direction outwardly to obtain a
perfect and complete action in the several respects stated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal Patent
Office on the 20th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, hearing date the Twenty-eighth day of January, in the
year of our Lord One thousand eight hundred and seventy-three, in the

page_text: traveller as short and the diameter of the ring as small as practicable to
obtain these ends. A light and delicate, or heavy and strong, but equally
even tension will also be at command in the same ring by changing the
sizo of the traveller; likewise facility and economy in the construction
of the parts and in their current use and repairs are obtained. The
Invention does away with that variation in the amount of friction which
is incidental to travellers of the description referred to consequent on
their deviations from a horizontal line, as the balancing point of the
traveller changes during the passage of the thread or yarn to the spindle
as the traveller approaches or recedes from it in the filling of the cop or
bobbin, such variation in friction producing irregularity of drag and
tension and consequently unevenness in the yarn or thread. The Inven-
tion likewise obviates any falling over and breaking down of the thread
incidental to an abrupt curve in the traveller, outside of which the
thread or yarn is liable to slip when the centrifugal force and enlarge-
ment of the cop or bobbin carries the thread towards the edge of the
ring. In such and similar travellers, as heretofore constructed, the
friction is too great and rigid against the inner edges of the ring, the same
creating too hard a tension, and wearing away both the ring and traveller
at the points of contact instead of (as effected by the present improve-
ments) causing the tension to be regulated as nearly as possible by the
vertical pressure of the traveller in its suspension upon the thread or
yarn. The latter and other advantages are attained by the present
Invention without using a ring and traveller of inconveniently large
dimensions to permit of the traveller moving outwardly from the
spindle far enough to build a cop or bobbin of suitable diameter.
The Invention consists in a novel construction of the annular shell or
cap, which is mounted upon or made to form a part of the ring by
providing the inner and under side of the cap with a bead or annular
projection of any desired shape in its transverse section so that in all
positions of the transverse bar or traveller the shell or cap shall afford an
uniform bearing at the points of contact, thereby producing an uniform
friction and tension upon the thread.
Furthermore the Invention consists in a transverse bar or traveller
with straight or nearly straight ends in line with each other, but with
its centre portion curved in a lateral direction outwardly to obtain a
perfect and complete action in the several respects stated.

page_text: In the accompanying Drawing Fig. 1 is a central vertical section of a
ring frame, having the Invention applied; and Fig. 2 is a plan illustrating
the transverse bar in certain different positions which it is free to assume
during operation, also showing the relative diameter of the outer disc, or
portion of the inner side of the ring, to that of the inner portion of the
shell or cap of the ring and the approximate length of a traveller that
will admit of a bobbin being spun of about the full size of the inner
portion of the ring without endangering its getting out when at the
centre of the ring.
A is the rotating spindle, extending upwards through the ring D; C is
the annular shell or cap, mounted on and forming part of the ring,
which latter is secured by an outer flange and screws to the lift rail E,
or may be otherwise secured. The cap C is constructed to turn inwards
at its top towards the spindle, and has its inner and under side formed
with an annular bead b, of flat, oval, round, or any other suitable shape,
in its transverse section, so that in varied positions of the transverse
bar G this cap will give an uniform bearing as regards its contact with
the bar in all positions of the latter (as is clearly shown in Fig. 2),
thereby producing an equal friction and tension upon the thread.
The traveller or transverse bar G (which is free to rotate with the spindle
within the ring D below the shell or cap C), may be made of steel or
other wire, or of any suitable material, and is shaped to have nearly or
quite straight ends c, c, in line with each other, and a laterally outwardly
curved central portion d which admits of its working outward around
the full bobbin. Such curved portion may either be variable or regular
but should form a direct junction as distinguished from a right angled
bend with the straight or nearly straight ends of the bar in line with
each other, as described. The yarn passing under the transverse bar G
to the spindle A, as described, is twisted and wound upon the spindle,
the yarn holding the bar against the spindle or yarn wound thereon, and
the bar as it rotates in common with the spindle being always kept in
a position to cause the yarn to pass to the spindle at an uniform angle
and consequently at an uniform tension, but admitting of the running at
a high rate of speed with a ring of suitable dimensions; also the con-
struction of the transverse bar doing away with any tendency of the
thread to slip outside of the bend when the bar occupies an outer
position relatively to the centre of the ring, and thereby avoiding all
falling over of the traveller and breaking down of the thread or yarn.

page_text: Friction, too, of the traveller is equalized by this Invention, and the
tension is regulated by the vertical pressure of the traveller in its
suspension upon the yarn, also the speed at which the spindle is run.
Having now described the Invention which has been communicated to
me by my foreign correspondents, and having explained the manner of
carrying the same into effect, I claim as the Invention secured to me by
Letters Patent as aforesaid,-
-
First. The ring D, formed or provided with an upper inwardly pro-
jecting or overhanging cap C in combination with a traveller arranged
for operation within the ring, as herein set forth.
Second. The combination with a transverse bar or traveller of the
bead on the under and inner side or margin of the cap C of the ring,
as described.
Third. The traveller or transverse bar G, constructed with straight or
nearly straight ends c, c, and an outwardly and laterally curved central
portion d for operating in common with the spindle and within the ring,
as herein set forth.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Twenty-fifth day of July, in
the year of our Lord One thousand eight hundred and seventy.
