Year: 1870

page_text: LETTERS PATENT to William Bywater, of Sweet Street Foundry,
Holbeck, near Leeds, in the County of York, and Jack Shaw,
of
Hunslet, in the said Leeds, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR DRAWING, SPINNING, AND TWISTING FLAX, Tow, WOOL,
WORSTED, SILK, COTTON, CHINA GRASS, OR OTHER FIBROUS SUBSTANCES."
Sealed the 17th March 1871, and dated the 23rd September 1870.
PROVISIONAL SPECIFICATION left by the said William Bywater and
Jack Shaw at the Office of the Commissioners of Patents, with their
Petition, on the 23rd September 1870.
We, WILLIAM BYWATER, of Sweet Street Foundry, Holbeck, near
Leeds, in the County of York, and JACK SHAW, of Hunslet, in the said
Leeds, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR DRAWING, SPINNING, AND TWISTING FLAX, Tow, WOOL,
WORSTED, SILK, COTTON, CHINA GRASS, OR OTHER FIBROUS SUBSTANCES," to be as
follows:-
Our improvements consist in the drawing, spinning, and twisting of
flax, tow, wool, worsted, silk, cotton, china grass, or other fibrous sub-

page_text: stances by means of a continuous draft between the delivery or holding
roller, with or without pressing or otherwise, and the bobbin of a roving
or spinning machine, such bobbin having a regular taking-up motion or
draft given it over the delivery or holding roller by means of a regulating
drag motion, thus drawing and spinning the sliver held by the delivery
or holding roller into a thread or yarn varying in thickness in proportion
to the thickness of the sliver or roving and the draft of the bobbin over
the roller, and twisting by means of the ordinary or other spindle and
flyer.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Bywater and Jack Shaw in the Great Seal
Patent Office on the 22nd March 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BYWATER, of Sweet Street Foundry, Holbeck, near Leeds, in the County
of York, and JACK SHAW, of Hunslet, in the said Leeds, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of September, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William Bywater and Jack Shaw, Her
special licence that we, the said William Bywater and Jack Shaw, our
executors, administrators, and assigns, or such others as we, the said
William Bywater and Jack Shaw, 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 "IMPROVEMENTS IN MACHINERY FOR
DRAWING, SPINNing, and TwistING FLAX, Tow, WOOL, WORSTED, SILK, COTTON,
CHINA GRASS, OR OTHER FIBROUS SUBSTANCES," upon the condition (amongst
others) that we, the said William Bywater and Jack Shaw, our executors
or administrators, by an instrument in writing under our or their hands
and seals, or under the hand and seal of one of us or them, 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

to each bobbin E; and each of these wheels F¹ is applied to a shaft
actuated from the drag motion, the speed of which may be varied at
pleasure to vary the speed of the bobbin E to suit the draft required on
the sliver or roving so as to make it into yarn, the spindle H and flyer I
being used for the purpose of putting the twist into the sliver or roving
at the same time as the bobbin E is drawing the sliver or roving to the
required thickness to make it into yarn. G is the bobbin and traverse
rail.
Having thus described a method we adopt in carrying our Invention
into operation, we would have it understood that we do not confine our-
selves to such method, as the same may be varied without departing from
the peculiar character of our improvements; but what we claim is, the
improvements in machinery for drawing, spinning, and twisting flax,
tow, wool, worsted, silk, cotton, china grass, or other fibrous substances,
whereby a continuous draft is produced between the delivery or holding
roller and the receiving bobbin by a drag motion capable of being
regulated.
In witness whereof, I, the said William Bywater, have hereunto set
my hand and seal, this Twentieth day of March, in the year of
our Lord One thousand eight hundred and seventy-one.
