Im- PROVEMENTS IN APPARATUS EMPLOYED IN DRAWING, SPINNING, OR TWISTING " PROVISIONAL SPECIFICATION
Year: 1874

page_text: LETTERS PATENT to William Bywater, of the Sweet Street Foundry,
Holbeck, Leeds, and Samuel Smith, of the Low Bridge Works,
Keighley, both in the County of York, for the Invention of "Im-
PROVEMENTS IN APPARATUS EMPLOYED IN DRAWING, SPINNING, OR TWISTING
"
PROVISIONAL SPECIFICATION left by the said William Bywater and
Samuel Smith at the Office of the Commissioners of Patents, with
their Petition, on the 20th February 1874.
We, WILLIAM BYWATER, of the Sweet Street Foundry, Holbeck,
Leeds, and SAMUEL SMITH, of the Low Bridge Works, Keighley, both
in the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS EMPLOYED IN DRAWING, SPINNING,
OR TWISTING WOOL OR OTHER FIBROUS SUBSTANCES," to be as follows:-
In drawing, spinning, and twisting apparatus it is customary for the
fibre to pass down direct from the delivery rollers to the spinning or
twisting means, and the draft to these delivery rollers is effected by

page_text: motion given to the lower of them aided by the weight of the upper
ones.
According to our Invention we can, if desired, dispense with the use
of the upper or pressing rollers, and instead of passing each sliver strand
or fibre simply over the upper surface of its bottom roller we pass each
sliver strand or fibre once or more times round such roller, and we
generally form the surface of these rollers of a square or other sided
figure, or of ridges or flutings to facilitate the drag on the yarn. These
rollers may be repeated in some cases to act in succession on the fibre to
form holding or drawing rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Bywater and Samuel Smith in the Great
Seal Patent Office on the 18th August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BYWATER of the Sweet Street Foundry, Holbeck, Leeds, and SAMUEL
SMITH, of the Low Bridge Works, Keighley, both in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twentieth day of February, in the
year of our Lord One thousand cight hundred and seventy-four, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said William Bywater and
Samuel Smith, Her special license that we, the said William Bywater
and Samuel Smith, our executors, administrators, and assigns, or such
others as we, the said William Bywater and Samuel Smith, 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 APPARATUS EMPLOYED IN DRAWING, SPINNING, OR TWISTING
WOOL OR OTHER FIBROUS SUBSTANCES," upon the condition (amongst others)
that we, the said William Bywater and Samuel Smith, our executors
.

page_text: 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 be filed in the Great Seal Patent Office within six calendar
months next and immediatly after the date of the said Letters Patent,
NOW KNOW YE, that I, the said William Bywater, on behalf of
myself and the said Samuel Smith, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
In drawing, spinning, and twisting apparatus it is customary for the
fibre to pass down direct from the delivery rollers to the spinning or
twisting means, and the draft to these delivery rollers is effected by
motion given to the lower of them aided by the weight of the upper
ones.
According to our Invention we, if desired, dispense with the use of
the upper or pressing rollers, and instead of passing each sliver strand
or fibre simply over the upper surface of its bottom roller, as is the
usual practice, we pass each sliver strand or fibre once or more times
round such roller, and we generally form the surface of these rollers of
a square or other sided figure or of ridges or flutings to facilitate the
drag on the yarn.
The Drawing, Figure 1, shews an arrangement of working parts of
such apparatus as usually adopted with the strand or yarn a in its
passage to the spinning or twisting means, passing simply over that
surface of the lower delivery roller 6 which for the time is the upper-
most, and between that surface and the under surface of the upper or
pressing roller c.
Figure 2 shows a corresponding arrangement of parts according to
our Invention, in which no upper or pressing roller is employed, and
the strand a is passed round the roller bin its passage to the guide eye
d and thence to the spinning or twisting means.
The roller b, as shown,
is of a square form, but this may be varied, and it may have ridges or
flutings on its surface as stated. These rollers may also be repeated,
if desired, to act in succession on the fibre to form holding or drawing
rollers.

page_text: Having thus described our Invention and means which we adopt in
carrying the same into effect, we would have it understood that what
we claim is, the arranging or combining apparatus employed in drawing,
spinning, or twisting wool or other fibrous substances, whereby the feed
or delivery rollers are formed of a square or other sided figure, or with
ridges or flutings to facilitate drag on the yarn passed around the same
in its passage to the spinning or twisting means, substantially as
described.
In witness whereof, I, the said William Bywater have hereunto
set my hand and seal, this Fifteenth day of August, in the year
of our Lord One thousand eight hundred and seventy-four.
WILLIAM BYWATER. (L.S.)
