CERTAIN IMPROVEMENTS IN AND APPLICABLE TO MACHINERY USED IN PREPARING AND SPINNING COTTON AND OTHER FIBROUS MATERIALS
Year: 1859

page_text: LETTERS PATENT to James Nuttall, of Todmorden, in the County of
York, Cotton Spinner and Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN AND APPLICABLE TO MACHINERY USED IN PREPARING AND
SPINNING COTTON AND OTHER FIBROUS MATERIALS."
Scaled the 10th February 1860, and dated the 31st August 1859.
PROVISIONAL SPECIFICATION left by the said James Nuttall at the
Office of the Commissioners of Patents, with his Pétition, on the
31st August 1859.
I, JAMES NUTTALL, of Todmorden, in the County of York, Cotton Spinner
and Manufacturer, do hereby declare the nature of the said Invention for
"CERTAIN IMPROVEMENTS IN AND APPLICABLE TO MACHINERY USED IN PREPARING
AND SPINNING COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
My Invention is applicable to the clearers of top rollers used in machinery,
for preparing and spinning cotton, and other fibrous materials; these top
clearers have hitherto been turned round by the friction of the top rollers,
consequently the surfaces of both clearers and top rollers travel at the same
speed. Now my Invention consists in driving the top clearers by gearing or
otherwise at a different surface velocity to that of the top rollers thereby
producing a rubbing action which is requisite in efficiently collecting the
flyings.

by the said James Nuttall in the Great Seal Patent Office on the
28th February 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
NUTTALL, of Todmorden, in the County of York, Cotton Spinner, and Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of August, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Nuttall, Her special licence that I, the said James Nuttall, my
executors, administrators, and assigns, or such others as I, the said James
Nuttall, my 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 AND
APPLICABLE TO MACHINERY USED IN PREPARING AND SPINNING COTTON, AND OTHER
FIBROUS MATERIALS," upon the condition (amongst others) that I, the said James
Nuttall, my executors, or administrators, by an instrument in writing under
my, or their, or one of 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 samo 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 James Nuttall, do hereby declare
the nature of my 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) :-
My Invention is applicable to the clearers of top rollers, used in machinery
for preparing and spinning cotton, and other fibrous materials; these top
clearers have hitherto been turned round by the friction of the top rollers.
Now my Invention consists in driving the top clearers by gearing.or
otherwise, at a different surface velocity to that of the top rollers, thereby
producing a rubbing action, which is requisite in efficiently collecting the
flyings.
And in order that my Invention may be fully understood, and readily
carried into operation, I will proceed to describe the accompanying Sheet
of Drawings which represents one mode of constructing my improvements.

page_text: Fig. 1 is an end elevation, and Fig. 2 a front view of the drawing rollers
of a machine for spinning, commonly called a throstle, to which my improve-
ments are applied; these improvements are however equally applicable to all
machines used in preparing and spinning, in which drawing rollers aro
employed; a is the front fluted roller, and 6 the top roller covered with flannel
and leather in the usual manner, c is the top clearing roller made as usual of
wood covered with flannel or in any other approved manner; the top clearers
are furnished with journals working in brackets fixed to the cap bars or stands,
and they are connected together at each stand by a square end, fitting into
a recess or socket, or they may be connected in any other convenient manner;
at one end of the front drawing roller a is a pinion a', gearing into a carrier
pinion d, which transmits motion to the pinion c¹, which revolves on a stud
fixed in the bracket e, and the end of the boss of this pinion is square to fit
in the socket, at the end of the first length of the top clearing rollers. The
number of teeth in the pinions a', and c', is so calculated that the surface of
the top clearers shall revolve faster than the surface of the top rollers, thereby
producing a rubbing action, which is essential in removing the flyings from
the surface of the top rollers, and collecting them on the top clearers. A
similar result, but not to the same extent, is produced by causing the surface
of top clearers to move slower than that of the top rollers.
Having thus stated the nature of my Invention, and described one mode
of carrying the same into operation, I wish it to be understood that I do not
limit myself to the details given, as the same may be considerably modified
or varied according to the peculiar construction of the machine, to which my
improvements are to be applied; but what I do claim is, the driving the
top clearers of machines used in preparing and spinning cotton and other
fibrous materials, by gearing or otherwise at a different surface velocity to
that of the top rollers, for the purpose described.
In witness whereof, I, the said James Nuttall have hereunto set my
hand and seal, this Twenty-seventh day of February, in the year of
our Lord One thousand eight hundred and sixty.

H. B. BARLOW, Patent Agent,
