Year: 1861

page_text: LETTERS PATENT to Frederick Tolhausen, Civil Engineer and Patent
Agent, of No. 35, Boulevart Bonne Nouvelle, Paris, in the Empire of
France, for the Invention of "A NEW KIND OF ARTIFICIAL FUR TO BE
MADE BY MEANS OF THE JACQUARD OR OTHER LOOM WITH SILK OR OTHER
TEXTILE MATERIAL."-A communication from Antoine Denis and Adolphe
Mottet, two persons resident at No. 35, Boulevart Bonne Nouvelle, Paris,
France.
Sealed the 21st February 1862, and dated the 26th August 1861.
PROVISIONAL SPECIFICATION left by the said Frederick Tolhausen at
the Office of the Commissioners of Patents, with his Petition, on
the 26th August 1861.
I, FREDERICK TOLHAUSEN, Civil Engineer and Patent Agent, of No. 35,
Boulevart Bonne Nouvelle, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "A NEW KIND OF ARTIFICIAL
FUR TO BE MADE BY MEANS OF THE JACQUARD OR OTHER LOOM WITH SILK OR
OTHER TEXTILE MATERIAL," to be as follows:-
This Invention relates to the manufacture of a kind of imitation fur
resembling to all intents and purposes that called Astrakan.
This imitation fur is produced either on the jacquard or on the common
loom in the following manner:-The textile matter intended for the weft,
which is composed of several ends, is first sized or dressed in a gelatinous

page_text: solution, then wound on tubular cops or spools, which are exposed to a heat
of about 150 degrees Fahrenheit, by which the fibres are made to curl. By
using this weft with the proper jacquard combination, a piled or terry fabric
is obtained, the weft forming the raised pile, which is then cut in the usual
way.
The pile or terry may also be obtained by means of the weft with what is
termed a satin or satinade shed. The process is similar to that used for
weaving velvet, and in order to cause the weft to curl, the wires or knives are
beated to a suitable degree, and are provided with a groove for guiding the
knives whilst cutting the pile. The pile may also be cut at the under side of
the fabric.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Tolhausen in the Great Seal Patent Office on the
24th February 1862.

formed, to be particularly described and ascertained in and by the following
statement:-
This Invention relates to the manufacture of a kind of imitation fur
resembling to all intents and purposes that called Astrakan.
I produce this imitation fur either on the jacquard or on the common loom
in the following manner:-The textile material intended for the weft, which is
composed of several ends, is first sized or dressed in a gelatinous solution,
then wound on tubular cops or spools, which are exposed to a heat of about
150 degrees F., by which the fibres are curled. By using this weft with the
proper jacquard combinations, a piled or terry fabric is obtained, the weft
forming the raised pile, which is then cut in the usual way.
The pile or terry may also be obtained by means of the weft with what is
termed a satin or satinade shed. The process is similar to that used for
making velvet. And in order to cause the weft to curl, the wires or knives
are heated to a suitable degree, and they are also provided with a groove for
guiding the knife whilst cutting the pile. The pile may also be cut on the
under face of the fabric.
In witness whereof, I, the said Frederick Tolhausen, have hereunto
set my hand and scal, this Twenty-second day of February, A.D.
