CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON OR OTHER FIBROUS SUBSTANCES." SP
Year: 1866

page_text: LETTERS PATENT to William Cameron Moore, Cotton Spinner, Jonathan
Mort Haslam, Manager, and John Robinson, Mechanic, all of Bamford,
in the County of Derby, for the Invention of "CERTAIN IMPROVEMENTS
IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON OR OTHER
FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said William Cameron Moore,
Jonathan Mort Haslam, and John Robinson at the Office of the
Commissioners of Patents, with their Petition, on the 11th May 1866.
We, WILLIAM CAMERON MOORE, Cotton Spinner, JONATHAN MORT HASLAM,
Manager, and JOHN ROBINSON, Mechanic, all of Bamford, in the County of
Derby, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY FOR PREPARING, SPINNING, AND DOUBLING COTTON
OR OTHER FIBROUS SUBSTANCES," to be as follows:-
Our Invention is designed for the purpose of preventing the waste and
accumulation of cotton or other fibrous materials upon the delivery rollers
employed in frames for preparing, spinning, or doubling cotton when the
"ends" break or the thread or twist become slack, and the improvements
consist in the novel employment and use of a bell crank or balance lever, the
fulcrum of which is secured to the framing of the roller bearings directly
beneath the top roller, the end of its longer arm or lever in front of the

page_text: machine being provided with a projecting pin or finger over which the thread
passes from the delivery rollers on toothed bobbins or spools. The opposite end
of this balance lever from its fulcrum is provided with a projecting pin which
forms the hinge or fulcrum of a swing plate which is caused constantly to
bear and rest upon that part of the periphery or surface of the botton roller
just at the entrance or point where the two rollers meet. When the machine
is in action, and during the time the thread remains continuous and the tension
uniform between the delivery rollers and the bobbin, the plate bearing upon
the bottom roller is prevented (by the thread passing over the pin or finger
on the end of the front arm of the lever) from moving in a forward direction,
but immediately the thread becomes slack or broken the front lever being
released causes the plate on the back lever to become inserted between the
top and bottom rollers below the twist, which has the effect of stopping the
revolution of the top roller, thereby preventing the delivery of yarn until the
ends are united.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said William Cameron
Moore, Jonathan Mort Haslam, and John Robinson in the Great Seal
Patent Office on the 3rd December 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CAMERON MOORE, Cotton Spinner, JONATHAN MORT HASLAM, Manager, and
JOHN ROBINSON, Mechanic, all of Bamford, in the County of Derby, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Ilerself, Iler heirs and successors, give and grant unto us, the said
William Cameron Moore, Jonathan Mort Haslam, and John Robinson, Her
special license that we, the said William Cameron Moore, Jonathan Mort
Haslam, and John Robinson, our executors, administrators, and assigns, or
such others as we, the said William Cameron Moor, Jonathan Mort Haslam,
and John Robinson, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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

page_text: IMPROVEMENTS IN MACHINERY FOR PREPARIRG, SPINNING, AND DOUBLING COTTON
OR OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that we,
the said William Cameron Moore, Jonathan Mort Haslam, and John
Robinson, our executors or administrators, by an instrument in writing
under our, or one of our 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 William Cameron Moore, 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 is designed for the purpose of preventing the waste and
accumulation of cotton or other fibrous materials upon the delivery rollers
employed in frames for preparing, spinning, or doubling cotton when the
"ends" break, or the thread or twist becoming slack, and the improvements
consist in the novel employment and use of a bell-crank or balance lever,
the fulcrum of which is secured to the framing of the roller bearings directly
beneath the top roller, the end of its longer arm or lever in front of the
machine being provided with a projecting pin, over which the thread passes
from the delivery rollers on to the bobbins or spools; the opposite end of the
balance lever from its fulcrum is provided with a projecting pin, which forms
the hinge or fulcrum of a swing plate, which is caused constantly to bear and
rest upon that part of the periphery or surface of the bottom roller just at the
entrance or point where the two rollers meet. When the machine is in
action, and during the time the thread remains continuous and the tension
uniform between the delivery rollers and the bobbin, the plate bearing upon
the bottom roller is prevented (by the thread passing over the pin or finger on
the end of the front arm of the lever) from moving in a forward direction;
but immediately the thread becomes slack or broken the front lever being
released causes the plate on the back lever to become inserted between the
top and bottom rollers below the twist, which has the effect of stopping the
revolution of the top roller, thereby preventing the delivery of yarn until
the ends are united.
In order that the Invention may be better understood and explained in
detail, we have hereunto attached a Sheet of Drawings made about the full
size, and having similar letters of reference marked thereupon.
Fig. 1 represents a detached vertical section of the delivery rollers and

page_text: supporting brackets of an ordinary doubling or twisting frame having our
improved apparatus applied.
In this view a is the top and b the bottom delivery rollers, between which
the yarn passes on its way to the flyer and bobbin; these rollers are supported
in the ordinary upper and lower brackets c and d; the upper bracket d is
provided with a projection or swell e, in which a stud is fixed, forming
the fulcrum of the balance lever f; the longer arm of this lever in front of
the rollers is provided with a stud 9, over which the thread passes, the tension
of which keeps the lever f depressed. The opposite end of the lever f behind
the fulcrum is also provided with a projecting pin h, which forms the fulcrum
or hinge of the swing plate or tongue i, which continually rests or bears upon
the bottom roller at the point where the surface of the two rollers impinge
on each other. It will be evident that as long as the machine remains in
action, and the thread is continuous and uniform in tension, the tongue or
plate bearing upon the bottom roller 6 is prevented from moving in a
forward direction; but immediately the thread becomes slack or broken the
front part of the lever f being released causes the plate i to move forward and
become inserted between the top and bottom roller below the twist, which
has the effect of stopping the revolution of the top roller, thereby preventing
the delivery of yarn until the ends are united.
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 the novel application, employment, and use of a
balance lever and plate, so arranged as to prevent the revolution of the top
roller when a thread becomes slack or disunited, as herein-before described,
set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said William Cameron Moore, have hereunto
set my hand and seal, this Ninth day of November, in the year of
our Lord One thousand eight hundred and sixty-six.
