page_text: LETTERS PATENT to Thomas Unsworth, of Manchester, in the County
of Lancaster, Machinist and Doubler, for the Invention of "IM-
PROVEMENTS IN FLYERS AND ÅRANGEMENTS FOR DRAWING YARN FROM THE
"
PROVISIONAL SPECIFICATION left by the said Thomas Unsworth at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd October 1874.
I, THOMAS UNSWORTH, of Manchester, in the County of Lancaster;
Machinist and Doubler, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN FLYERS AND ARRANGEMENTS FOR DRAWING YARN
FROM THE SAME FOR SPINNING AND DOUBLING ALL FIBRES," to be as follows:-
In my Patent Banding Machine dated April 25th 1871, No. 1088, and
my Patent Doubling Machine dated Jany. 17th 1873, No. 195, I use
two-legged flyers with two eyelets (in some cases) at the end of the legs,
and in others one at the end and another half way between the end and
the shoulder. This arrangement of cyelets I still use in my present

page_text: Invention with the addition of one, two, or more plain legs, round which
from the bobbin I pass the yarn before taking it through the lower or
central eyelet, and thence through the one at the end of the leg, and
over a guide or pulley on a rod immediately over the centre of spindles;
and if for cable laying, over the machine; but if for doubling, through
the stretching rollers on to the bobbins in the taking-up crcel. This
arrangement of flyer forms a traverse without the aid of wheels or their
equivalent.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Unsworth in the Great Seal Patent Office
on the 9th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
UNSWORTH, of Manchester, in the County of Lancaster, Machinist and
Doubler, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of October, in
the year of our Lord One thousand eight hundred and seventy-four, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Thomas Unsworth, Her
special licence that I, the said Thomas Unsworth, my executors, admi-
nistrators, and assigns, or such others as I, the said Thomas Unsworth,
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 FLYERS AND ARRANGEMENTS FOR DRAWING YARN FROM THE
SAME FOR SPINNING AND DOUBLING ALL FIBRES," upon the condition (amongst
others) that I, the said Thomas Unsworth, my exccutors or admini-
strators, by an instrument in writing under my, or their, or one of
their hands and scals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be

page_text: 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 Unsworth, 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 :-
-
This Invention relates to the flyer used in banding twine, thread
doubling, and all kinds of doubling or twisting machines, whereby the
traverse motion (absolutely necessary with the ordinary flyer) is entirely
dispensed with by the simple addition of one, two, or more plain legs
equally distanced from each other and fairly balanced. The thread or
yarn passing from the bobbin round one of these plain legs, which when
in motion causes the yarn in coming off the bobbin to traverse up or
down in almost a straight line from the bobbin (thus preventing breakage
of the yarn) through the eyelet on the middle of the next leg round
and through the cyclet at the end of the same leg, thence through a
guide or over a guide pully or other guide on a rod over the centre of
the spindle, thence (if for cable laying) across the machine, but if for
once twisting, round the stretching rollers on to the bobbin in taking-up

page_text: Having now described my Invention and the-way in which I work it,
I wish it to be distinctly understood that what I claim as novel, and
therefore secured to me herein is,―
First. The flyer made with additional leg or legs, substantialy as and
for the purposes herein-before set forth.
Second. The method of drawing yarn from the same through guides
or over pullies, substantialy as and for the purposes herein-before set
forth.
In witness whereof, I, the said Thomas Unsworth, have hereunto
set my hand and seal, this Sixth day of April, in the year of
our Lord One thousand eight hundred and seventy-five.
Witness,

Engineer, &c.,
