A MACHINE UPON NEW AND IMPROVED PRINCIPLES FOR THE PURPOSE OF DOUBLING EITHER SILK, COTTON, FLAX, HEMP, WORSTEAD YARN, OR OTHER THREADS
Year: 1800

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SHARRER WARD, of Bruton, in the County of Somerset, Silk Throwster, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirtieth day of December, in the forty-first year of His
reign, give and grant unto me, the said John Sharrer Ward, His especial
licence, that I, the said John Sharrer Ward, during the term of years therein
mentioned, should and lawfully might use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "A MACHINE
UPON NEW AND IMPROVED PRINCIPLES FOR THE PURPOSE OF DOUBLING EITHER SILK,
COTTON, FLAX, HEMP, WORSTEAD YARN, OR OTHER THREADS;" in which said Letters
Patent is a contained a proviso obliging me, the said John Sharrer Ward,
under my hand and seal, to cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, to be inrolled
in His Majesty's High Court of Chancery within one calendar month after the
date of the said recited Letters Patent, as in and by the same (relation being
thereunto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Sharrer Ward do hereby declare that my said Invention is described in
manner following (that is to say):-
Whatever number of threads are required to be doubled together of silk,
worstead, cotton, flax, &c., they may by means of this Invention be doubled to
the greatest certainty; for if at any time any one of the threads or union of
threads to be so doubled should break, it will immediately stop the other thread
until the broken thread shall be repieced, which secures a constant double

page_text: thread or union of threads, and the manner in which the same is to be
performed is described and ascertained in the Plan hereunto annexed, and
which is explained and referred to in the letters, figures, and words following
(that is to say) :-
Figure 1. A is a roller turning round vertically or otherwise, with it is
carried the bobbin B, which draws the thread C, C, from the bobbins D, D,
and consequently the balls E, E, and the thread wires F, F, will move round
on the pins G, G. H, H, are two wood or iron standards, at the tops of which
are hung two regulating thread wires I, I. When either of the threads C, C,
breaks, the thread wire through which it passes falls down, and the tail part K
rises up to a level with the ball E, and stops the other thread wire F from
going round; and consequently the thread that passes through it and prevents
the bobbin B from taking it up, but the roller A continues in motion. L, L.
are guide wires for the threads to pass over. M is a slide moved by a stort
wheel or crank to lay the threads level on the bobbin.
Figure 2 is another doubling machine, the form varied, but the principle the
same as Figure 1-A, a roller turning vertically, whereon lies a smaller one
marked B, the axis of which goes through the bobbin. C, a slide for the
same purpose as M, in Figure 1. D, D, two bobbins with spindles through
them, on each of which is fixed a wheel E, E. F, F, are two thread wires
hung at G, G When either of the threads breaks, the wire drops' between
the teeth of the wheel, and stops the other thread, the bobbin and roller B
stopping at the same time; but the roller A continues moving as A in
Figure 1.
In witness whereof, I, the said John Sharrer Ward, have hereunto set a
my hand and seal, the Twenty-seventh day of January, in the year
of our Lord One thousand eight hundred and one.
