Year: 1866

page_text: LETTERS PATENT to Ferdinand Wilhelm Kaselowsky, of Bielefeld, in
the Kingdom of Prussia, Flax Spinner, for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR CARDING THE TOW OF FLAX, HEMP, OR JUTE, AND
FIBROUS SUBSTANCES, AND SEPARATING THE WOODY PARTICLES
THEREFROM."
Sealed the 29th March 1867, and dated the 4th October 1866.
PROVISIONAL SPECIFICATION left by the said Ferdinand Wilhelm
Kaselowsky at the Office of the Commissioners of Patents, with his
Petition, on the 4th October 1866.
I, FERDINAND WILHELM KASELOWSKY, of Bielefeld, in the Kingdom of
Prussia, Flax Spinner, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR CARDING THE TOW OF FLAX, HEMP, OR JUTE,
AND OTHER FIBROUS SUBSTANCES, AND SEPARATING THE WOODY PARTICLES
THEREFROM," to be as follows:-
I fix scutching blades made of steel or other suitable metal on the working
cylinders or rollers of carding engines by placing them at convenient intervals
between the segments of the covering or clothing of cards. Thus when the
carding engines are worked and the tow is passing over them the blades are

page_text: brought into contact with the tow, and thereby scrape off the woody particles
at the same time as the operation of carding is being performed. The blades
need not be of any particular form.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ferdinand Wilhelm Kaselowsky in the Great Seal Patent
Office on the 4th April 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FERDINAND
WILHELM KASELOWSKY, of Bielefeld, in the Kingdom of Prussia, Flax
Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of October, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Ferdinand Wilhelm Kaselowsky, Her special licence that I, the said
Ferdinand Wilhelm Kaselowsky, my executors, administrators, and assigns,
or such others as I, the said Ferdinand Wilhelm Kaselowsky, 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 APPARATUS FOR CARDING THE
Tow OF FLAX, HEMP, OR JUTE, AND OTHER FIBROUS SUBSTANCES, AND SEPARATING
THE WOODY PARTICLES THEREFROM," upon the condition (amongst others) that
I, the said Ferdinand Wilhelm Kaselowsky, 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 Ferdinand Wilhelm Kaselowsky, do
hereby declare 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 Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to say):-
This Invention relates to the application to carding engines of a novel
contrivance for removing from the tow under treatment the woody particles

page_text: while the carding or combing operation is proceeding. To this end I fix
scutching blades or plates made of steel or other suitable metal across the
main cylinders, and when workers and strippers are used across the stripper
roller or stripper rollers also. These blades or plates I place at convenient
intervals between the segments of the covering or clothing of cards, and when
in their revolution they are brought into contact with the tow while pendent
from the feeding trough, they will scrape off the woody particles from the
forward ends thereof. To complete the operation I also fix in the main frame
concentrically with the main cylinder and the stripper roller or rollers
respectively (when the latter are used) a series of plates, which will act on
the tail or rear end of the fibres in the same way as the rotating scutching
plates.
In the accompanying Drawing Fig. 1 shews in side or end elevation a
carding engine with the parts applied forming the subject of the present
Invention. A is the main framing of the carding engine; B is the rotating
main cylinder clothed with cards in the usual way; C is the ordinary feeding
roller covered with pins or teeth and rotating in a cast-iron trough D, through
which the tow to be carded is conducted to the main cylinder B; F is a
worker covered with leather filletting; E is a stripper roller, and G is a doffer
roller covered with leather filletting and cleared by the doffing knife H. The
whole of the above mentioned parts are arranged as in the ordinary carding
engine. K, K, K, are a number of plates of steel or other suitable material
mounted transversely on the periphery of the cylinder B at intervals between
segments of covering of the usual kind, viz., wood staves fitted with projecting
steel pins. The edges of these flat plates K, which are bevilled as shewn in
the Drawing, are laid in the direction of rotation of the cylinder B, and they
may lie in the same line as or project a little above the line of the points of
the pins of the usual covering. L, L, L, are a series of fixed plates, arranged
concentrically with respect to the working cylinder and placed at a convenient
distance from the edges of the revolving plates K. These plates L present
their sharp edges to the advancing teeth of the cylinder, and may be continued
if thought desirable round the greater portion of the periphery of the cylinder
(dispensing in that case with the worker and stripper), or any number of
workers and strippers may be introduced and set around the main cylinder.
In the Figure I have shown a single pair of working and stripping rollers
applied to the carding engine. The surface of the stripper is covered alter-
nately with the plates K, and segments of wood and steel pin covering, and a
series of fixed 'scutching plates L is set around the stripper. It will be seen
that as the foremost ends of the fibres of tow are presented to the cylinder B

page_text: over the edge of the trough D, they are alternately combed out by the pins as
in ordinary carding engines, and scraped by the action of the plates K until
the fibres are carried off by the pins on the cylinder. This forward motion of
the fibres brings their opposite or rear ends into contact with the edges of the
fixed plates L, and being lashed against those edges the remaining woody
particles will be scraped off the fibres or combed or carded tow. Where
workers and strippers are used, as illustrated in the Drawing, the same
operation is repeated, the tow being held by the teeth of the worker F, whilst
the teeth and plates on the stripper E comb out and scrape off the woody
parts from the fibre. The stripper is then cleared by the cylinder B, and
the cleaned fibres are carried forward to the doffer, which strips them off
from the cylinder and is itself cleared of the fibres by the knife H in the
usual way.
Having now set forth the nature of my Invention of "Improvements in
Apparatus for Carding the Tow of Flax, Hemp, or Jute, and other Fibrous
Substances, and separating the Woody Particles therefrom," I wish it to be
understood that under the above in part recited Letters Patent I claim, the
application to carding engines of scutching blades or plates, in the manner and
for the purpose above set forth.
In witness whereof, I, the said Ferdinand Wilhelm Kaselowsky, have
hereunto set my hand and seal, the Twenty-eighth day of March, in
the year of our Lord One thousand eight hundred and sixty-seven.
