IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING
Year: 1871

page_text: LETTERS PATENT to William Moscrop, of Red Lumb, near Rochdale,
in the County of Lancaster, Cotton Spinner and Manufacturer, for
the Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING AND
DOUBLING."
Sealed the 8th August 1871, and dated the 24th February 1871.
PROVISIONAL SPECIFICATION left by the said William Moscrop at
the Office of the Commissioners of Patents, with his Petition, on
the 24th February 1871.
I, WILLIAM MOSCROP, of Red Lumb, near Rochdale, in the County
of Lancaster, Cotton Spinner and Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR SPINNING
AND DOUBLING," to be as follows:-
:—
My Invention is applicable to throstle, spinning, and doubling frames,
and it consists in an improved construction of flyer or instrument by
which the yarn is wound on the bobbin.
In flyers of the usual construction the flyer legs are connected to the
boss by means of straight arms or shoulders; now my Invention consists

page_text: in making these arms or shoulders of a curved or part of a screw form.
The object of making the arms or shoulders of this peculiar form is to
convey the yarn in passing from the ordinary guide wire to the bobbin
beyond the top flange of the bobbin; by this means the frequent break-
ages in consequence of the yarn being caught on the top flange of the 5
bobbin is prevented, and the production of the machine is increased; the
lift of the bobbin may also be increased.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Moscrop in the Great Seal Patent Office
on the 21st August 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MOSOROP, of Red Lumb, near Rochdale, in the County of Lancaster,
Cotton Spinner and Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of February, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Moscrop, Her
special licence that I, the said William Moscrop, my executors, adininis-
trators, and assigns, or such others as I, the said William Moscrop, 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 "IMPROVE-
MENTS IN MACHINERY FOR SPINNING AND DOUBLING," upon the condition
(amongst others) that I, the said William Moscrop, my exccutors or
administrators, by an instrument in writing under my, 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 Moscrop, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
My Invention is applicable to throstle, spinning, and doubling frames,
and it consists in an improved construction of flyer or instrument by
which the yarn is wound on the bobbin.
In flyers of the usual construction the flyer legs are connected to the
boss by means of straight arms or shoulders; now my Invention consists
in making these arms or shoulders of a curved or part of a screw form.
The object of making the arms or shoulders of this peculiar form is to
convey the yarn in passing from the ordinary guide wire to the bobbin
beyond the top flange of the bobbin. By this means. the frequent break-
ages in consequence of the yarn being caught on the top flange of the
bobbin are prevented and the production of the machine is increased;
the lift of the bobbin may also be increased.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters
marked thereon.
Fig. 1 is an elevation of the spindle and bobbin of an ordinary
throstle frame to which my improved flyer is applied, and Fig. 2 is a
plan of the same.
a is the spindle, the bobbin, and c my improved flyer. In the
elevation it will be seen that my improved flyer is similar to the ordinary
flyers, but on referring to the plan it will be seen that the arms or
shoulders for connecting the legs to the boss of the flyer instead of being
straight as usual are of a double curved form. The object of this
peculiar form is to convey the yarn (which is indicated by the line d)
to the bobbin beyond the top flange of the bobbin. In flyers of the
usual construction the yarn is liable to rub on the top flange of the
bobbin, and unless the said flange be perfectly smooth the twist of
the
yarn is irregular or the yarn carries the bobbin round, thus causing
a breakage, or what is known by the name of a "snarl," but by making
the arms or shoulders of the improved form shewn or any analagous
form the above defects are avoided, and the production of the machine
is increased. Should it be desirable to increase the drag the yarn can
be carried direct from the guide wire to the eye of the flyer, as the
improved form will hold the yarn free from the top flange of the bobbin
without its being passed round the leg of the flyer. It will be obvious

page_text: that the lift may be increased without incurring the danger of the yarn
rubbing on the top flange of the bobbin.
Having thus stated the nature of my Invention and described the
manner of performing the same, I declare that I claim, making the arıns
or shoulders of flyers for spinning and doubling machines of a curved 5
described.
or part of a screw form for the purposes
In witness whereof, I, the said William Moscrop, have hereto set
my hand and scal, this Eighteenth day of August, One thousand
eight hundred and seventy-one.
