CERTAIN IMPROVEMENTS IN MACHINERY POR ROVING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1832

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TRAVIS the younger, of Shaw Mills, near Manchester,' in the 'County
Palatine of Lancaster, Cotton Spinner, send greeting.
WHEREAS His most Excellent Majesty King William the Fourth did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-ninth day of
September, in the third 'year of His reign, give and grant unto me," the said
John Travis, my executors, "administrators, and assigns, His espécial license;
full power and 'sole privilege and authority, that I, the said John Travis, my
exécutors, administrators, and assigns, should and lawfully might, during the
term of fourteen years therein mentioned, make, use, exercise, and vend, within
England and Wales and the Town of Berwick-upon-Tweed, 'a certain Invention
of "CERTAIN IMPROVEMENTS IN MACHINERY POR ROVING COTTON AND OTHER FIBROUS
SUBSTANCES in which said Letters Patent there is contained a proviso that if I.
the said John Travis, 'should not particularly describe and ascertain the nature
of the said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, and cause the same to be
enrolled in His Majesty's High Court of Chancery within six calendar months
then next and immediately after the date of the said Letters Patent, that then
the said Letters Patent, and all liberties and advantages thereby granted,
should utterly cease, determine, and become void, as in and by the same,
relation being thereunto had, may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Travis the younger, do hereby declare that my Improvements in
Machinery for Roving Cotton and other Fibrous Substances, consist in a
certain novelty in the formation of the flyers, by which rovings are laid upon
the bobbins, and also in the mode of driving them; which improvements
are particularly shewn in the Drawing hereunto annexed.
Figure 1 is a front view of one spindle, with its bobbin and the flyer con-
nected with it, which are shewn detached from the machine. Figure 2 is a
side view of the same represented partly in section..
a is the spindle supported in a stop b, screwed into the copping rail c. The
bobbin d is attached to the spindle a, bearing upon the boss e, which is made
fast to the spindle by a screw. The spindle is driven by the wheel upon the
horizontal rotary shaft g, which takes into the pinion h, fixed on the spindle;
these are made to rise and fall by any of the ordinary modes of effecting the
copping. The arms of the flyer i, i, are continued downwards, and united to
a boss at the bottom, seen best in the sectional Figure. Upon this boss is fixed
the pinion 1, and the flyer is supported at bottom by the perforated bracket m,
which is affixed to a stationary horizontal rod n, and the figure is kept per-
pendicular and held at top by a similar perforated bracket o affixed to a
stationary horizontal rod p, the rods n and p being made fast to the frame-
work of the machine. The flyer is made to revolve by means of a wheel q
upon the horizontal rotary shaft r, which wheel takes into the pinion l, fixed
as aforesaid upon the boss at bottom of the flyer. It will now be seen that
the spindle and flyer move independently of each other, and that if different
speeds are given to the shafts ƒ and g they will be made to revolve with dis-
similar velocities, and hence that the rovings coming through the central tube
at top, and down one of the arms of the flyer, will be wound upon the bobbin
uniformly as the copping rail moves the spindle up and down.
Having described the nature of my improvements, and the manner in which
the same are to be carried into effect, lastly, I declare that I claim as my In-
vention the peculiar construction of the flyer for roving cotton, wool, and other
fibrous materials, in connection with the mode of adapting and actuating the
same as described above.
In witness whereof, I, the said John Travis, have hereunto set my hand
and seal, this Twenty-seventh day of March, One thousand eight
hundred and thirty-three.
JOHN (L.S.) TRAVIS.
