page_text: LETTERS PATENT to John Leach, of Ashton-under-Lyne, in the County
of Lancaster, Cotton Spinner, and John Anderson, of the same Place,
Manager, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY

PROVISIONAL SPECIFICATION left by the said John Leach and John
Anderson at the Office of the Commissioners of Patents, with their Petition,
on the 25th March 1868.
We, JoWN LEACH, of Ashton-under-Lyne, in the County of Lancaster,
Cotton Spinner, and JOHN ANDERSON, of the same Place, Manager, do hereby
declare the nature of the said Invention for "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER
FIBROUS SUBSTANCES," to be as follows:-
Our Invention relates to all descriptions of machinery for preparing and
spinning cotton and other fibrous substances wherein "drawing, rollers" are
employed, and the improvements consist in the employment and use of
"bottom rollers" having smooth surfaces or peripheries, in contradistinction to
such surfaces being fluted, grooved, roughened, or rendered otherwise uneven,
such uneven surfaces having been regularly employed and considered necessary
bitherto, whereas by the use of "bottom rollers" made with smooth surfaces

page_text: or peripheries a considerable improvement is effected in the yarn, the covered
"top rollers are not injured as by fluted rollers, and the hold upon the fibres
or yarns is not diminished.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Leach and John Anderson in the Great Seal Patent
Office on the 23rd September 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
LEACH, of Ashton-under-Lyne, in the County of Lancaster, Cotton Spinner,
and JOHN ANDERSON, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Leach and John Anderson, Her special license that we, the
said John Leach and John Anderson, our executors, administrators, and
assigns, or such others as we, the said John Leach and John Anderson, 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 "CERTAIN IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR PREPARING AND SPINNING COTTON AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that we, the said John Leach and John
Anderson, our executors or administrators, by an instrument in writing under
our, or one of our, or their, or one of their hands and seals, should par-
ticularly 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 immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Leach, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say):-
Our Invention relates to all descriptions of machinery for preparing and
spinning cotton and other fibrous substances wherein " drawing rollers" are
employed, and the improvements consist in the employment and use of front

page_text: "bottom rollers" having smooth surfaces or peripheries, in contradistinction
to such surfaces being fluted, grooved, roughtened, or rendered otherwise
uneven, such fluted or uneven surfaces having been regularly employed, and
considered necessary hitherto, whereas by the use of front "bottom rollers"
made with smooth surfaces or peripheries a considerable improvement is
effected in the quality of the yarn, the leather-covered "top rollers" are not
injured as by fluted rollers, and the hold upon the fibres or yarn is not
diminished.
We would here remark, that since the filing of the Provisional Specification
we have ascertained that the portion of our Invention included by the words
"other fibrous substances" used therein is not so novel or original nor of such
utility as we then considered it to be, and we therefore hereby disclaim that
portion of the Invention; and we would remark, in conclusion, that we claim
the novel employment and use of smooth surfaced "front bottom drawing
rollers" in all machines wherein drawing rollers are used for preparing and
spinning cotton, in contradistinction to the use of fluted or grooved rollers as
bitherto employed in such position for such purpose.
In witness whereof, I, the said John Leach, have hereunto set my hand
and seal, this Twenty-second day of September, in the year of our
Lord One thousand eight hundred and sixty-three.
