Year: 1864

page_text: LETTERS PATENT to John Prestwich, the younger, of Farnworth, in the
· County of Lancaster, and William Brooks, of the same Place, for the
Invention of "IMPROVEMENTS IN DRAWING AND OTHER FRAMES USED IN
PREPARING COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN."
PROVISIONAL SPECIFICATION left by the said John Prestwich and
William Brooks at the Office of the Commissioners of Patents, with
their Petition, on the 31st March 1864.
We, JOHN PRESTWICH, the younger, of Farnworth, in the County of
Lancaster, and WILLIAM BROOKS, of the same Place, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN DRAWING AND OTHER
FRAMES USED IN PREPARING COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN,"
to be as follows:-
This Invention relates to all preparing machines in which a clearer is
employed, and consists in placing the clearer in contact with the first and
second rollers of the frame, the clearer being driven at the same speed as the
second roller, and kept up to the aforesaid rollers by means of a spring, lever,
or weight, or by causing its pivots or shaft to work in stationary or moveable
brackets or bearings.
This arrangement has the effect of keeping the first and second rollers and
also the clearer free from dirt and refuse.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Prestwich and William Brooks in the Great Seal
Patent Office on the 30th September 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PRESTWICH, the younger, of Farnworth, in the County- of Lancaster, and
WILLIAM BROOKS, of the same Place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said John Prestwich, the younger, and William Brooks, Her special
license that we, the said John Prestwich, the younger, and William Brooks,
our executors, administrators, and assigns, or such 'others as we, the said
John Prestwich, the younger, and William Brooks, our executors, adminis-
trators, 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 DRAWING AND OTHER FRAMES USED IN
PREPARING COTTON OR OTHER FIBROUS MATERIALS TO BE SPUN," upon the condition
(amongst others) that we, the said John Prestwich, the younger, and William
Brooks, our executors or administrators, by an instrument in writing under
our, or their, or one of our or their hands and seals, 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 immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Prestwich, the younger, and
William Brooks, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say) :-
This Invention relates to all preparing machines in which a clearer is
employed, and consists in placing a revolving clearer in contact with the first
and second rollers of the frame, the clearer being driven at the same speed
as the second roller, and kept up to the aforesaid rollers by means of a spring,
lever, or weight, or by causing its pivots or shaft to work in stationary or
moveable brackets or bearings.

page_text: In the accompanying Sheet of Drawings Fig. 1 is an end elevation of part
of a drawing frame, the first and second rollers of which have our improved
revolving clearer in contact with them, and Fig. 2, a transverse section of the
lower rollers drawn about full size. In both Figures a represents the first or
front roller; b, the second roller; and c, the revolving clearer, the surface
speed of which should be the same as that of the second roller.
This arrangement has the effect of keeping the first and second rollers and
also the clearer free from dirt and refuse, and it is evident that the system
can be applied to all preparing machines in which a clearer is employed.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we claim in preparing machines placing a revolving clearer
in contact with the first and second bottom rollers of the frame for the purpose
of keeping the rollers and clearer free from dirt and refuse, as such improve-
ments are herein described and illustrated in the accompanying Sheet of
Drawings.
In witness whereof, I, the said John Prestwich, the younger, for and
on behalf of myself and the said William Brooks, have hereunto set
my hand and seal, this Twenty-seventh day of September, in the year
of our Lord One thousand eight hundred and sixty-four.
Signed, sealed, and delivered by the
within-named John Prestwich,
the younger, in the presence of
E. J. HUGHES,
Patent Agent,
Manchester.
JOHN PRESTWICH, JN. (L.S.)
