CERTAIN IMPROVEMENTS CARDING ENGINES FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES."
Year: 1861

page_text: LETTERS PATENT to Ferdinand Ziffer, of Vienna, in the Empire
Austria, Engineer, for the Invention of "CERTAIN IMPROVEMENTS
CARDING ENGINES FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Ferdinand Ziffer at the
Office of the Commissioners of Patents, with his Petition, on the 18th
June 1861.
I, FERDINAND ZIFFER, of Vienna, in the Empire of Austria, Engineer, do
hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN CARDING ENGINES FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES," to be
as follows:-
My Invention consists in the novel application and use of a semicircular
grid or cage beneath the main cylinder and other cylinders in carding engines,
for the purpose of retaining the "fly" or loose filaments of cotton or other
fibrous substance, and allowing dust and other extraneous matter to fall
through. This grid or cage is semicircular in form, and is composed of round
rods extending from one end of the cylinder to the other in the direction of its
length, and placed close to the periphery of the "card cylinders," so that the
filamentous substance may be gathered from the "grid" by the cards, and
passed through the engine.

by the said Ferdinand Ziffer in the Great Seal Patent Office on the
18th December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FERDINAND
ZIFFER, of Vienna, in the Empire of Austria, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Ferdinand Ziffer, Her special license that 1, the said Ferdinand
Ziffer, my executors, administrators, and assigns, or such others as I, the
said Ferdinand Ziffer, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 CARDING ENGINES FOR CARDING COTTON AND OTHER FIBROUS
SUBSTANCES," upon the condition, amongst others, that I, the said Ferdinand
Ziffer, by an instrument in writing under my hand and seal, 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 Ferdinand Ziffer, 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):-
My Invention consists in the novel application and use of a semicircular
grid or cage beneath the main cylinder and other cylinders in carding engines,
for the purpose of retaining the "fly" or loose filaments of cotton or other
fibrous substances, and allowing dust and other extraneous matter to fall
through. This grid or cage is semicircular in form, and is composed of round
rods, extending from one end of the cylinder to the other in the direction of
its length, and placed close to the periphery of the "card cylinders," so that
the filamentous substance may be gathered from the "grid" by the "cards,"
and passed through the engine.
In order that the Invention may be clearly understood and explained in
detail, I have hereunto annexed a Sheet of Drawings illustrative of the same,

page_text: in which Fig. 1 represents a sectional view of a carding engine, and Fig. 2 a
Diagram of the wire grid.
In Fig. 1, a, a, is the grid formed of wires placed side by side, and secured
to a wood or metal framing, as seen in Fig. 2, and situated beneath the licker-
in b, and main cylinder c, in such a manner as to retain the loose filaments
falling therefrom, so as to be again taken up by the cylinders and passed
through the carding engine.
Having now described the nature of the said Invention, together with the
manner of performing the same, I wish it to be distinctly understood that I
claim the application and use of a semicircular "grid or cage," formed of wire
beneath the "licker-in" and main cylinder in carding engines, for the purpose
of retaining the "fly," and allowing the dust and other impurities to fall
through, as herein-before described, set forth, and fully exhibited in the
Drawings attached.
In witness whereof, I, the said Ferdinand Ziffer, have hereunto set my
hand and seal, this Seventeenth day of December, in the year of
our Lord One thousand eight hundred and sixty-one.
FERDINAND ZIFFER. (LS.)
