CERTAIN IMPROVEMENTS IN SELF-ACTING MULES' FOR SPINNING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1860

page_text: LETTERS PATENT to John Kay, of Burnley, in the County of Lancaster,
Cotton Spinner, and John Hartley of the same Place, Manager, and
Thomas Mallinson, of Manchester, in the same County, Machinist, for
the Invention of "CERTAIN IMPROVEMENTS IN SELF-ACTING MULES' FOR
SPINNING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 19th April 1861, and dated the 25th October 1860.
PROVISIONAL SPECIFICATION left by the said John Kay, John Hartley,
and Thomas Mallinson at the Office of the Commissioners of Patents,
with their Petition, on the 25th October 1860.
We, JOHN KAY, of Burnley, in the County of Lancaster, Cotton Spinner,
and JOHN HARTLEY, of the same Place, Manager, and THOMAS MALLINSON, of
Manchester, in the same County, Machinist, do hereby declare the nature of the
said Invention for "CERTAIN IMPROVEMENTS IN SELF-ACTING MULES' FOR SPINNING
COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
Our Invention applies particularly to the well-known machine called "Sharp
and Roberts' Self-acting Mule," or to any other inule of a somewhat similar
construction, wherein a "quadrant" is used or employed to regulate the
winding of the yarn upon the "spindle," and consists in a novel arrangement
of apparatus, whereby we make such regulation self-acting in the manner as
shewn in the accompanying Drawing, where a represents the "quadrant," and
b, a bevil wheel mounted upon the centre stud, and attached to the ordinary
bevil wheel in gear with the pinion c on the end of the screw, the bevil wheel b

page_text: gearing with another wheel d, revolving in connection with the catch box, disc,
or friction coupling e on an upright fixed stud, the sliding part of such catch
box having a groove turned on it, in which works a band or other equivalent
attached to the spindle carriage A, and passed round a carrying pulley, so that
the traverse of the carriage causes the part f to revolve, it being at the same
time free to slide into gear with the part c, when raised by the end of the
lever g, which is effected by the weight h depressing the other end, the weight
being suspended from the levers of the two "fallers" i, ', by a chain or cord
attached to the levers, as shewn, and furnished with suitable means of adjust-
ment, whereby the weight is kept clear of the lever until such times as the
"tension faller" is depressed by overwinding, when the weight being lowered
into contact with the lever presses it down, thus throwing the catch box into
action, whereby the screw is caused to revolve by means of the bevil wheels until
the necessary regulation being effected, the "tension faller" rises, carrying with
it the weight, thus leaving the sliding part of catch box free to drop out of gear
with the part attached to the bevil wheel d.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Kay, John Hartley, and Thomas Mallinson in the Great
Seal Patent Office on the 25th April 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
KAY, of Burnley, in the County of Lancaster, Cotton Spinner, and Jonn
HARTLEY, of the same Place, Manager, and THOMAS MALLINSON, of Manchester,
in the same County, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of October, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Kay, John Hartley, and Thomas Mallinson, Her special license that
we, the said John Kay, John Hartley, and Thomas Mallinson, our executors,
administrators, and assigns, or such others as we, the said John Kay, John
Hartley, and Thomas Mallinson, 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
IMPROVEMENTS IN SELF-ACTING MULES FOR SPINNING COTTON AND OTHER FIBROUS

page_text: SUBSTANCES," upon the condition, amongst others, that we, the said John Kay,
John Hartley, and Thomas Mallinson, or one of us, by an instrument in
writing under our hand and seal, or under the hand and seal of one of us,
should particularly describe and ascertain the nature of our 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 Thomas Mallinson, 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 and accompanying Drawings (that is to say):-
Our Invention applies particularly to the well-known machine called "Sharp
and Roberts'" self-acting mule, or to any other mule of a somewhat similar
construction, wherein a "quadrant" is used or employed to regulate the wind-
ing of the yarn upon the "spindle," and consists in a novel arrangement of
apparatus, whereby we make such regulation self-acting.
In order that the Invention may be clearly understood and explained in
detail, I have hereunto attached a Sheet of Drawings, made upon a scale of
about two inches to the foot, and having similar letters of reference marked
upon corresponding parts in both Figures.
In Fig. 1 and 2, a represents the quadrant, and b a bevil wheel mounted
upon the centre stud, and attached to the ordinary bevil wheel in gear with the
pinion c, which is on the end of the screw. The bevil wheel b gears with
another wheel & revolving in connection with the catch box dise or friction
coupling e on an upright fixed stud, the sliding part f of such catch box having
a groove turned on it, in which works a band or other equivalent attached to
the spindle carriage A, and passed round a carrying pulley, so that the traverse
of the carriage causes the part f to revolve, it being at the same time free to
slide into gear with the part e when raised by the end of the lever g, which is
effected by the weight h being suspended from the levers of the two "fallers"
i, i, by a chain or cord attached to the levers, as shewn and furnished with
suitable means of adjustment, whereby the weight is kept clear of the lever
until such time as the "tension faller" is depressed by overwinding, when
the weight being lowered into contact with the lever, presses it down, thus
throwing the catch box into action, whereby the screw is caused to revolve by
means of the level wheels until the necessary regulation being effected, the
"tension faller" rises, carrying with it the weight, thus leaving the sliding part
of catch box free to drop out of gear with the part attached to the bevil
wheel d

page_text: Having now described the nature of the said Invention, together with the
manner of carrying the same into practical effect, we wish it to be distinctly
understood that we claim the novel employment and use of the lever g, and
apparatus in connection therewith, as shewn for operating upon the quadrant
screw to regulate the winding up of the thread, as herein-before described, set
forth, and fully exhibited in the Drawings attached.
In witness whereof, I, the said Thomas Mallinson, have hereunto set my
hand and seal, this Twenty-fourth day of April, in the year of our
Lord One thousand eight hundred and sixty-one.
THOS. MALLINSON. (L.S.)
