IMPROVEMENTS IN EMERY ROLLERS FOR GRINDING CARDS
Year: 1872

page_text: LETTERS PATENT to George Newsome, of Rochdale, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN EMERY ROLLERS
FOR GRINDING CARDS."
Sealed the 25th October 1872, and dated the 8th May 1872.
PROVISIONAL SPECIFICATION left by the said George Newsome at the
Office of the Commissioners of Patents, with his Petition, on the
8th May 1872.
I, GEORGE NEWSOME, of Rochdale, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
EMERY ROLLERS FOR GRINDING CARDS," to be as follows:-
This Invention relates to the emery rollers employed for grinding the
points of the wire cards used in carding engines, and consists principally
in making such rollers with plain spaces or cavities intervening between
strips or surfaces of emery in contradistinction to covering the entire
surface with emery as ordinarily practised. These alternate spaces or
cavities and emery surfaces both grind the cards better than the plain
emery rollers, and the spaces also allow of room for the dirt and grease
to escape.

page_text: I prefer to use alternate spaces or cavities and strips of emery,
arranged in a slightly spiral form, like a quick threaded screw, having
(say) four threads; but the emery may be laid on in various other ways
so as to leave spaces or cavities in any other suitable form to provide for
the exit of the crease and dirt from the ends of the roller.
i
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Newsome in the Great Seal Patent Office
on the 8th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
NEWSOME, of Rochdale, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of May, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said George Newsome, Her special license that I, the said
George Newsome, my executors, administrators, and assigns, or such
others as I, the said George Newsome, 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 "IMPROVEMENTS IN EMERY ROLLERS FOR GRINDING
CARDS," upon the condition (amongst others) that I, the said George
Newsome, 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 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 George Newsome, 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 and accompanying Drawings (that is to say) :-
This Invention relates to the emery rollers employed for grinding the
points of the wire cards used in carding engines, and consists principally

page_text: in making such rollers with plain spaces or cavities intervening between
strips or surfaces of emery in contradistinction to covering the entire
surface with emery, as ordinarily practised. These alternate spaces or
cavities and emery surfaces both grind the cards better than the plain
emery rollers, and the spaces also allow of room for the dirt and greaso
to escape.
I prefer to use alternate spaces or cavities and strips of emery,
arranged in a slightly spiral form, like a quick threaded screw, having
(say) three or four threads; but the emery may be laid on in various
other ways, so as to leave spaces or cavities in any other suitable form to
provide for the exit of the grease and dirt from the ends of the roller.
The annexed Drawing represents at Fig. 1 a side view, and at Fig. 2
a transverse section (enlarged) of an emery roller, having the emery laid
on in three spiral lines, strips, or surfaces a, a, a, leaving narrow spiral
spaces or cavities b, b, b, between them for the escape of the grease and
dirt from the ends of the roller, as above described.
Having now described the nature and object of my said Invention for
"Improvements in Emery Rollers for Grinding Cards," together with
the manner in which the same is to be or may be performed or carried
into practical effect, I wish it to be understood that I claim as my In-
vention, making such rollers with plain surfaces or cavities intervening
between strips or surfaces of emery, whether such alternate plain surfaces
and surfaces of emery are arranged in the spiral form, shown in the
Drawing, or in any other suitable manner.
In witness whereof, I, the said George Newsome, have hereunto
set my hand and seal, this Sixth day of November, in the year
of our Lord One thousand eight hundred and seventy-two.

GEORGE DAVIES, O.E.,
Patent Agent,
