Year: 1868

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN SPINNING
MACHINERY." A communication from abroad by Henry Tatem
Potter and Joseph Griswold Lamb, both of Norwich, in the State of
-
Connectiont Tinited States of America.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 25th March 1868.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SPINNING
MACHINERY," to be as follows:-
Much difficulty has been experienced with the ring travellers hitherto
devised from the unequal tension exerted upon the yarn in passing
to the spindle, such inequalities in the tension not only rendering
“እ

page_text: the yarn extremely liable to be broken in the spindle, but also
causing material variations in the size thereof.
This Invention is designed to remedy these objections, and it consists
in the use of a transverse bar 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, whereby the yarn is caused to
pass to the spindle at a uniform angle and is consequently kept at
an uniform tension, thus effectually securing the desired result.
The Invention further consists in providing lateral openings at the
external portion of the ring through which lint, dirt, and the like
may escape from the annular guide in which the ends of the transverse
bar are placed. The ring is made with two internal rims, the one
overlapping the other and forming together a ring groove to receive
the bent ends of the transverse bar which is thereby held in place at
the same time that the free movement of the bar around the spindle
is provided for.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 25th September 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED 2
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of March, in the
year of our Lord One thousand eight hundred and sixty-eight, in the 2
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her
special licence that I, the said Alfred Vincent Newton, my executors,
administrators, and assigns, or such others as I, the said Alfred
Vincent Newton, my executors, administrators, and assigns, should at g
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain, and Ireland, the Channel Islands, and Isle of Man, an

page_text: Invention for "IMPROVEMENTS IN SPINNING MACHINERY," being a communi-
cation to me from abroad, upon the condition (amongst others) that I,;
the said Alfred Vincent Newton, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and.
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
heretunto annexed, and to the letters and figures marked thereon (that
is to say):-
Much difficulty has been experienced with the ring travellers hitherto
devised from the unequal tension exerted upon the yarn in passing
to the spindle, such inequalities in the tension not only rendering the
yarn extremely liable to be broken in the spindle but also causing
material variations in the size thereof.
This Invention is designed to remedy these objections, and it consists
in the use of a transverse bar 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, whereby the yarn is caused to
pass to the spindle at an uniform angle and is consequently kept at
an uniform tension thus effectually securing the desired result.
The Invention further consists in providing lateral openings at the
external portion of the ring through which lint, dirt, and the like may
escape from the annular guide in which the ends of the transverse
bar are placed.
The Invention further consists in an internal rim or flanch so
arranged upon the ring and with reference to the transverse bar as to
retain the same in proper position both when in use and during the
operation of ménding a break in the yarn.
The Invention further consists in a novel means whereby the ends
of the transverse bar are held in place at the same time that the free:
movement of the bar around the spindle is provided for.

a ring frame furnished with a traveller constructed according to this
Invention; Fig. 2 is a plan view of the ring and traveller; Fig. 3 is
a central vertical transverse section of the same taken transversely to
Fig. 1; Fig. 4 is a side view of one portion of the apparatus, and
Fig. 5 is a plan view shewing a modified form of the Invention.

the external
The rotating spindle A may be of any suitable form and construction
and extends upwards through the ring B in the usual manner; the
ring B has its upper edge turned inward as shewn at a¹ and formed
thereon at the internal periphery of this upper part of the ring is an
outwardly extending rim or flanch a.
Provided upon
circumference of the ring is a rib or shoulder b, and fitted upon the
ring and secured thereto by screws or their equivalents is an annular
shell C which rests upon the rib b. The outer edge of this annular
shell is turned inward toward the internal rim or flanch a as shewn
in Figures 1 and 3, and any desired number of elongated openings c
are formed in the sides of the shell, their office being to allow any
lint, dirt, or other obstructing material which might otherwise be
retained in the annular groove or guide constituted by the space c¹
between the portion a¹ of the ring and the inwardly turned edge of
the shell C to escape therefrom, thereby preventing any interference
with the movement herein-after fully described of the transverse
travelling bar D of the apparatus. This transverse bar is fully shown
in Figures 1 and 2. It consists of a piece of steel or other wire,
the main and central portion of which is slightly curved as repre-
sented at a while the ends are bent nearly at right angles thereto
as at " to form the sides of the bar, the extremities c₁ being turned
outwards at right angles to the sides that they may enter the space
or guide c¹ between the inwardly extending edge of the shell, and
the portion a¹ of the ring, such space forming a guide in which the
extremities of the transverse bar may traverse in the operation of the
device or apparatus above described. The rim or flanch a serves to
prevent the central or main portion of the bar from dropping through
the ring, and also to retain the same in position in case the yarn
should break and require mending or at the starting of the device to
work. The yarn passing over the transverse bar D to the spindle A
as shewn in red outline in Figures 1, 2 and 5, is twisted and wound
upon the spindle, the yarn as it passes thereto holding the bar against

page_text: the same or against the yarn wound thereon, and inasmuch as the
bar D as it is carried around with the spindle by the rotation of the
same is always kept in a position tangential to the circumference of
such spindle, it follows that the yarn in passing to the spindle over
the bar will be always kept at the same angle to such circumference
and drawing as a consequence with a uniform degree of force upon
the bar D be subjected to a uniform tension, the tension being of
course proportional to the weight of the bar, and the friction exerted
upon the ends thereof as they traverse or pass around within the guide c.
Not only is a more uniform tension exerted upon the thread by this
means, but inasmuch as the dragging action which produces this tension
is exerted upon the thread at a point much nearer the spindle than
is the case with the ordinary ring traveller, it follows that the tendency
of the tension to draw the fibres apart when such point is at a greater
distance from the spindle than the length of the fibre is effectually
counteracted. In the modified form shewn in Fig. 5 the bar instead
of being of the shape herein-before described is made straight, its ends
working in a suitable annular groove or guide formed internally in the
ring.
Having now set forth the nature of the Invention of improvements
in spinning machinery as communicated to me from abroad, and
explained the manner of caraying the same into effect, I wish it to
be understood that under the above in part recited Letters Patent,
I claim, the application to spinning machinery of the ring and
traveller constructed and operating in the manner and for the purposo
above described.
In witness whereof, I, the said Alfred Vincent Newton, have here-
unto set my hand and seal, the Twenty-fifth day of September, in
the year of our Lord One thousand eight hundred and sixty-eight.
