Year: 1855

page_text: LETTERS PATENT to David Anderson, of Strandtown House, in the County
of Down, Ireland, Merchant, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR THE PREPARATION OR MANUFACTURE OF FELT
AND OTHER FIBROUS MATERIALS."
Sealed the 20th May 1856, and dated the 3rd December 1855.
PROVISIONAL SPECIFICATION left by the said David Anderson at the
Office of the Commissioners of Patents, with his Petition, on the 3rd
December 1855.
I. DAVID ANDERSON, of Strandtown House, in the County of Down, Ireland,
Merchant, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR THE PREPARATION OR MANUFACTURE OF
FELT AND OTHER FIBROUS MATERIALS" to be as follows, that is to say :-
This Invention relates to the use of a compound machine or a combination
Hitherto felt has been manu-
of machinery for the manufacture of felt.
factured in or by separate and detached preparing and finishing machines:
Now, according to the present Invention, the primary preparing machine, or
"devil," acting as a teaser or opener, is combined and worked in concert with
the finishing cylinder or apparatus, the two working together as one machine.
With this arrangement the operations are conducted with superior facility,
economy, and effect. The same mechanical combination or arrangement, or
modifications thereof, may be applied and used in the manufacture, carding,
or teasing of flax, tow, jute, hair, wool, cotton, and other fibrous materials.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
ANDERSON, of Strandtown House, in the County of Down, Ireland, Merchant,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of December, in the year of our Lord One
thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Eler heirs and successors, give and grant unto me, the said
David Anderson, Her special license that I, the said David Anderson, my
executors, administrators, and assigns, or such others as 1, the said David
Anderson, my executors, administrators, or 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
MACHINERY OR APPARATUS FOR THE PREPARATION OR MANUFACTURE OF FELT AND
OTHER FIBROUS MATERIALS," upon the condition (amongst others) that I,
the said David Anderson, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, 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 David Anderson, do hereby declaro the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,
reference being had to the accompanying Drawings, that is to say:
My said Invention relates to the use of a compound machine or a com-
bination of machinery to be used for the preparation or manufacture of felt
and other fibrous materials.
And in order that my said Invention may be properly understood, I have
hereunto appended a Sheet of Drawings, illustrating the practical carrying out
thereof. Hitherto, to the best of my knowledge and belief, felt has been
manufactured in or by separate and detached preparing and finishing machines. 3
According to the present Invention, however, the primary preparing machine,.
or "devil," acting as a teaser or opener is combined and worked in concert
with the finishing cylinder or apparatus, the two working together as one

page_text: machine, as represented in external side elevation on the Sheet of Drawings
hereunto attached. With this arrangement, the operations are conducted
with superior facility, economy, and effect. The same mechanical com-
bination or arrangement, or modifications thereof, may be applied and used
in the manufacture, carding, or teasing of flax, tow, jute, hair, wool, cotton,
and other fibrous materials.
An additional improvement consists in fitting to the wire cylinder a self-
acting door, which opens and closes at each revolution, and causes a constant
current of air to pass through, thereby cleansing the materials operated upon
from impurities.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I may observe, in conclusion, that I do not confine or restrict
myself to the precise details or arrangements which I have had occasion to
describe or refer to, as many variations may be made therefrom without
loviating from the principles or main features of my Invention; but what
I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent, is, the
combining together in one machine the preparing and finishing apparatus
hitherto used separately in the manufacture of felt and other fibrous materials,
as herein-before described.
In witness whereof, I, the said David Anderson, have hereunto set my
hand and seal, this Twenty-eighth day of May, One thousand eight
hundred and fifty-six.
DAVID ANDERSON. (L.S.)
