County of Lancaster, Cotton Spinner, and William Cudworth, of the
same Place, Manager, for the Invention of "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER FIBROUS
MATERIALS."
Sealed the 12th August 1859, and dated the 5th May 1859.
PROVISIONAL SPECIFICATION left by the said John Scholfield and
William Cudworth at the Office of the Commissioners of Patents, with
their Petition, on the 5th May 1859.
We, JOHN SCHOLFIELD, of Milnrow, near Rochdale, in the County of
Lancaster, Cotton Spinner, and WILLIAM CUDWORTH, of the same Place,.
Manager, do hereby declare the nature of our said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:-
This Invention relates to that class of spinning machines called "mules,".
"twiners," &c., and consists in making that part of the "mule which
regulates the speed of the spindles when "winding-on" self-acting, in the
following manner :-To one of the levers carrying the "faller" rod is attached
a vertical rod working in guides, in such a manner as that when the "faller" is.
drawn down by the over tension of the threads, the lower end of the rod comes
into contact with a sliding bar mounted on a guide bed, so as to slide freely in
the direction of the traverse of the mule carriage. To this sliding bar one

page_text: end of a cord is attached, which passes round a grooved pulley fast to a bevil
wheel mounted on the same shaft or stud as the "quadrant," and which gears
into a pinion fast to the lower end of the "quadrant screw," the upper end
being furnished with a ratchet wheel and pawl, to cause the screw to turn
only in the direction which shall cause the nut block carrying the chain to
traverse outwards from the centre of the "quadrant," the chain acting to
regulate the speed of the spindles in the usual manner. As soon as the
tension of the thread is diminished, the "faller" rises, carrying with it the
vertical rod, thereby releasing the sliding bar, which is drawn back by a
weight attached to the free end of the cord, the cord slipping on the band
pulley without turning it.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Scholfield and William Cudworth in the Great Seal
Patent Office on the 5th November 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wе, JOHN
SCHOLFIELD, of Milnrow, near Rochdale, in the County of Lancaster, Cotton
Spinner, and WILLIAM CUDWORTH, of the same Place, Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, IIer heirs and successors, give and grant unto us,
the said John Scholfield and William Cudworth, Her special license that we,
the said John Scholfield and William Cudworth, our executors, administrators,
and assigns, or such others as we, the said John Scholfield and William
Cudworth, our 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 "CERTAIN IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR SPINNING COTTON AND OTHER FIBROUS
MATERIALS," upon the condition, amongst others, that we, the said John
Scholfield and William Cudworth, or one of us, by an instrument in writing
under our hands and seals, or under the hand and seal of one of us, 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

page_text: in the Great Seal Patent Office within six calendar months next and im-
mediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Scholfield, do hereby declare the
nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
This Invention relates to that class of spinning machines known as "mules,"
"twiners," &c., and consists in making that part of the mule which regulates
the speed of the spindles when "winding-on," self-acting, in the following
manner: To one end of the levers carrying the "faller rod" a vertical. rod is
attached, working in guides in such a manner that when the "faller " is
drawn by the over tension of the threads, the lower end of the rod comes
into contact with a sliding bar mounted on a guide bed, so as to slide freely in
the direction of the traverse of the "spindle carriage." To this sliding bar
one end of a cord is attached, which passes round a grooved pulley secured to
a bevil wheel, mounted on the same shaft or stud as the "quadrant," and
which gears into a pinion upon the lower end of the "quadrant screw," the
upper end being furnished with a ratchet wheel and pawl, to cause the screw
to turn only in the direction which shall cause the "nut block" carrying the
chain to traverse outwards from the centre of the "quadrant," the chain
acting so as to regulate the speed of the spindles in the usual manner. When
the tension of the threads is diminished, the faller rises, carrying with it the
vertical rod, thereby releasing the sliding bar, which is drawn back by a weight
attached to the free or loose end of the cord, the cord slipping on the band
pulley without turning it.
In order that the Invention may be better understood and explained in
detail, we have hereunto annexed a Sheet of Drawings illustrative of the same,
and made upon a scale of about one inch and a half to a foot, and having
similar letters of reference marked upon corresponding parts of the apparatus
in both the Figures exhibited.
Fig. 1 exhibits a cross sectional view of the spindle carriage and the portion
of the mule framing and "headstock" to which our present improvements
apply; Fig. 2 is a front view of the same.
In Fig. 1, a, a, is a portion of the mule framing; and b, b, the spindle
carriage, constructed in the usual manner; c, c, being the spindles, and d, d,
the "fallers" and "faller rods." At one end of the levers which are connected
with the "fallers and rods" d, d, the vertical rod e is attached, and slide in the
guides f, the lower end of such rod resting upon the sliding and stepped
bar g, sliding on the guide bed k, to which bar g is attached the cord i, which

page_text: passes round guide pulleys and over the pulley k, upon which is the bevil
wheel l, gearing with the bevil pinion m, which turns the screw n, and thereby
works the screw block o further from the centre of the "quadrant" p, and so
regulates the formation of the cop and the "winding-on" of the thread from
the commencement to the completion, the action being as follows:-When
the "cop bottom" is commenced, the thread is "wound on" at the lower end
of the spindle only, and gradually increases in diameter, and consequently the
tension of the thread becomes greater, and the "faller" is thereby depressed.
and the vertical rod e is forced down into any one of the "steps" on the
sliding bar g, according to the amount of tension, and as the spindle carriage
"runs out" this bar is carried in the same direction, and the cord attached
turns the pulley k, bevil wheel l, and pinion m, which turns the screw, and the
"screw block" o is propelled along the screw, and by thus shortening the
winding on of the chain on the drum q, as usual, the speed of the driving
drum is altered, and the spindles are thereby driven quicker or slower
according to the amount of surface to be "wound on" in the gradual
formation of the "cop."
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, we wish it to be distinctly
understood that we claim regulating the speed of the spindles in the aforesaid
class of spinning machinery, in accordance with the amount of surface to be
"wound on," so as to produce a firmer and more regularly "built" cop, by
means of the mechanism and apparatus herein-before described, set forth, and
fully exhibited in the Drawings annexed.
In witness whereof, I, the said John Scholfield, have hereunto set my
hand and seal, this Fourth day of November, in the year of our Lord
One thousand eight hundred and fifty-nine.
JOHN SCHOLFIELD. (L.S.)
