IMPROVEMENTS IN MULES FOR SPINNING
Year: 1864

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN MULES FOR SPINNING."-A communication
from abroad by Pierre Adolphe Schlumberger, of Guebwiller, Haut
Rhin, in the Empire of France.
Sealed the 20th October .1864, and dated the 16th May 1864. :
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
16th May 1864.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MULES FOR SPINNING,"
to be as follows:-
In ordinary self-acting mules for spinning, the mechanism hitherto employed
for causing the carriage to move backward and forward has consisted of two
cords or straps, one end of which has been attached to the carriage, and the
other end to a piece of mechanism termed a scroll. The consequence is that
when the carriage is moved the strain is liable to come only on one cord or
strap, thereby destroying it or deranging the machine in a short time...
The object of the present Invention is to remedy this defect by employing
a single cord or strap attached by its ends to the two scrolls, and passing round

page_text: a loose pulley pivotted on the carriage, and thus by the play given to the cord
or strap by the pulley, the strain is equalised throughout.
The same effect may be obtained by attaching two cords to a rocking
lever, are, or wheel pivotted on the carriage, the other ends of the cords being
secured to the scrolls.
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 16th November 1864.
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, bearing date the Sixteenth day of May, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Edward Newton, Her special license that I, the said
William Edward Newton, my executors, administrators, and assigns, and
such others as I, the said William Edward Newton, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time, and at all times thereafter, during the term thereby granted,
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 Invention for "IMPROVEMENTS IN MULES FOR SPINNING," being a com-
munication to him from abroad upon the condition (amongst others) that
I, the said William Edward Newton, by an instrument in writing under
my hand and seal, 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 William Edward 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 hereunto annexed
and to the letters and figures marked thereon (that is to say) :-
In ordinary self-acting mules for spinning, the mechanism hitherto

page_text: employed for causing the carriage to move backward and forward has
consisted of two cords or straps, one end of which has been attached
to the carriage, and the other end to a piece of mechanism termed a scroll;
and as the cords and also the scrolls sometimes vary in diameter, the strain
on the cords, or the major part of the strain when the carriage is moved in
or out by the cords, is liable to come only on one cord or strap, thereby
destroying it or deranging the machine in a short time.
The object of the present Invention is to remedy this defect by employing
a single cord or strap attached by its ends to the two scrolls, and passing
such cord or strap round a loose pulley pivotted on the carriage, and thus
by the play given to the cord or strap by the pulley, the strain will be
equalized throughout.
The same effect may be obtained by dividing the cord into two parts,
and attaching the divided ends to a rocking lever, arc, or wheel, pivotted on
the carriage, the other ends of the cords being secured to the scrolls in the
usual manner.
In the accompanying Drawing I have shewn so much of a self-acting mule
as will be necessary to understand the Invention.
Fig. 1 being a sectional elevation, and Fig. 2 a plan view of an arrange-
ment in which a single cord or strap a, a, is attached, by its two ends to the
scrolls b, b, and passes round the pulley c, which is mounted on the vertical
spindle or axle d, in the carriage e of the spinning frame.
It will be evident from this arrangement that the cord a will be kept at
the same tension throughout its entire length. Should the cord become
stretched, however, so as to become loose, it may be tightened by drawing
up the pulley c by means of the screw f, for which purpose the spindle d of
the pulley c is mounted in a block g which is capable of moving between the
guides h, h, when the screw f is turned round.
Instead of a single cord a which passes round a pulley c, as in Figs. 1 and 2,
this cord may be divided into two parts as seen at a, a', Figs. 3 and 4, and
the divided ends may be attached to the arms of a rocking lever c', which is
mounted on the vertical spindle or axle d, as seen in Fig. 3, in place of the
pulley c of Figs. 1 and 2; or the divided ends a, a¹, of the cord may be
secured to a rocking arc or wheel c³, as shewn in Fig. 4. It will be evident
that the equilibrium of the cord or cords a, a¹, may be maintained by various
other mechanical arrangements, which will however be merely mechanical
equivalents for those shewn and described.
Having now described this Invention of improvements in mules for
spinning, and having explained the manner of carrying the same into effect,

page_text: as communicated to me by my foreign correspondent, I claim as the Inven-
tion secured to me by Letters Patent as aforesaid, the mode herein set forth
of equalizing the strain on the cord or strap which actuates the carriage of
self-acting mules.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Ninth day of November, in
the year of our Lord One thousand eight hundred and sixty-four.
Witness,
J. W. MOFFATT,
