Year: 1858

page_text: LETTERS PATENT to Jesse Brierley, of Kirkheaton, in the County of
York, Manufacturer, for the Invention of "IMPROVEMENTS IN MACHINERY
An
ADDADAZUG FOR SPINNING WOOL AND OTUND FIBRES
"
Sealed the 28th January 1859, and dated the 29th July 1858.
PROVISIONAL SPECIFICATION left by the said Jesse Brierley at the
Office of the Commissioners of Patents, with his Petition, on the 29th
July 1858.
I, JESSE BRIERLEY, of Kirkheaton, in the County of York, Manufacturer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING WOOL AND OTHER FIBRES," to be as
follows:-
This Invention relates to spinning on the "mule" wool and other fibres
carded or prepared by the "condenser," and the improvements consist in
causing the spindles of the mule not to rotate, or to rotate slowly during a
part or the whole length of the draught or "taking in" of the length of sliver
required to be spun at each draw out of the carriage, consequently giving
little or no twist to the said sliver during such taking in, whereby I am
enabled to produce a more uniform and a better thread, more free from
"twits" or other small places than when the spindles are continually in full
motion, thereby giving too much twist to the sliver during that part of the
draught as heretofore; which improvements 1 effect by applying a slip box,

page_text: traverse pullies, or other suitable driving apparatus to the spindles, which is
capable of being adjusted and rendered self-acting, so as to throw them in
and out of motion at any desired time or place, either by the motion of the
SPECIFICATION in pursuance of the conditions of_the_Letters Patent, filed
by the said Jesse Brierley in the Great Seal Patent Office on the 28th
January 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JESSE
BRIERLEY, of Kirkheaton, in the County of York, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of July, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Jesse Brierley, Her special licence that I, the said Jesse Brierley, my
executors, administrators, and assigns, or such others as I, the said Jesse
Brierley, my executors, administrators, and assigns, should at 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 Invention for "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR SPINNING WOOL AND
OTHER FIBRES," upon the condition
(amongst others) that I, the said Jesse Brierley, 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 Jesse Brierley, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,
(that is to say):-
-
This Invention relates to spinning on the mule wool and other fibre, carded
or prepared by the condenser, and my improvements consist in causing the
spindles of the mule not to rotate, or to rotate slowly during a part or the
whole length of the draught or taking in of the length of the sliver required
to be spun at, each draw out of the carriage, consequently, giving little or no

page_text: twist to the said sliver during such taking in, whereby I am enabled to
produce a more uniform or better thread, and more free from twits or small
places than when the spindles are continually in full motion, by which too
much twist is given to the sliver during that part of the draught; which
improvement I effect by applying a slip box or catch box, traverse pulleys,
or other suitable driving apparatus to the spindles which is capable of being
adjusted and rendered self-acting, so as to throw them in and out of motion at
any desired time or place, either by the motion of the carriage as it is moved
in and out, or by the twist gear.
The manner in which my Invention is to be performed will be readily
understood by reference to the accompanying Sheet of Drawings, similar
letters referring to the same parts in each of the Figures.
Fig. 1 is an end elevation of such parts of a spinning mule head as is
necessary to shew the application of my Invention; and Fig. 2 is a side
elevation of the same with my improvements attached.
A, represents the rim shaft with the driving pulleys, &c., thereon; B, the
twist pulleys, which receive motion from the rim shaft A; and C, the twist
gear. All of which parts are shewn as in ordinary use, and are well under-
stood by mule spinners. D is a pulley affixed on the rim shaft, which gives
motion to the pulley E, which is loose on the shaft which carries the twist
pulleys, the boss of which forms one part of the catch box a. F is another
pulley, loose on the same shaft, with a corresponding part of the catch box b
formed on its boss, and with a bevil rim or flange c on the other side. This
pulley is capable of sliding on the shaft, so as to gear or bring together the
catch box a, b, or slide in the other direction when the bevil rim c enters into
a recess formed in the twist pulleys, by the friction of which full motion is
given thereto. Fig. 3 is a plan of these parts on a larger scale, with the
twist pulleys in section, shewing the action thereof. G is an upright shaft
with a forked lever H, which takes into a groove in the boss of the pulley F.
The lever I is fixed to the bottom end of the upright, to which is attached a
strong spiral spring J, which keeps the pulley F in contact with the twist
pulleys. K is another lever, fixed to the top of the upright, and attached
thereto is a rod L, extending to the back part of the mule, the end of which
is so constructed and arranged that when the carriage is put up or back, it
comes in contact with this rod, the force of which draws the pulley F out
of contact with the twist pulleys, and into gear with the pulley E by the catch
box a, b. The rod L is held back by a drop catch M. A stud N, which can
be fixed in any desired position on the twist gear shaft, comes in contact with
and lifts the catel, liberating the rod L, when the spring J immediately

page_text: operates and draws the pulley F into contact with the twist pulleys again;
thus the change of the speed of the spindles is alternately made, and by
adjusting the stud N on the twist gear shaft the change may be effected at
any point of the draught, also by varying the relative-sizes-of-the-pulleys
here employed so can the speed or motion of the spindles be varied.
The advantage of this my said Invention, as applied to the spinning of
wool carded on the "condenser," will be apparent to any one conversant with
the spinning of slubbing prepared by the condenser, which has no-twist, and
of slubbing prepared by the ordinary carding engine, which has a certain
amount of twist in the opposite direction, and which is now taken out by the
spindles rotating in a contrary direction during the draught.
Having thus fully described the nature of my Invention, and the manner
in which the same is performed or carried into practical effect, I would have
it distinctly understood that I do not confine myself to the precise details of
construction or arrangement of the machinery as herein set-forth, as such may
be varied or modified without departing from the spirit or main feature of
my Invention; but what I claim and believe to be new within the realm is,
the constructing, arranging, or applying apparatus to spinning mules for
causing the spindles not to rotate, or to rotate slowly during the draught or
part thereof as may be required when spinning wool prepared by the con-
denser, as herein described and illustrated in the accompanying Sheet of
Drawings.
In witness whereof, I, the said Jesse Brierley, have hereunto set my
hand and seal, this Twenty-fifth day of January, in the year of our
Lord One thousand eight hundred and fifty-nine.
Signed, sealed, and delivered by the
within-named Jesse Brierley, in
the presence of
WM. TASKER, Patent Agent,
Halifax.
