Year: 1876

page_text: LETTERS PATENT to Frank Wirth, of the Firm of Wirth and Company, Patent
Agency, of Frankfort-on-the-Main, in the Empire of Germany, for the Invention
of IMPROVEMENTS IN WOVEN FABRICS." A communication from Jules Carrey,
Manufacturer, residing at Mülhausen (Alsatia).
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office of
the Commissioners of Patents on the 4th February 1876.
FRANK WIRTH, of the Firm of Wirth and Company, Patent Agency, of Frankfort-
on-the-Main, in the Empire of Germany. "IMPROVEMENTS IN WOVEN FABRICS." A
communication.
My Invention consists of an improvement in woven fabrics, by which articles
woven according to my Invention and afterwards pattern printed have the
appearance of having the pattern woven into the substance and not printed on the
surface. This is accomplished by having the warp or weft threads permanently
dyed so as to resist the after process of printing, or in running a second fast dyed
thread by side of the ordinary warp or weft threads, the permanently dyed threads
being distinctly visible after the printing process is over, give each mesh a distinct
and separate appearance, and a raised look to the other threads, the pattern thus
seems apparently woven into the tissue.
The characteristic novelty of this Invention having been shown, the same is used
to give effect to patterns and designs printed on woven substances, so as to give the
said patterns or designs the appearance of being woven or worked on the tissue,
this being produced by having the threads running in one direction, either weft or
warp permanently dyed, or by introducing by the side of the weft or warp a second
thread permanently dyed. These foot dyed threads are not affected by the printing,
and laying by side of the thread which take the pattern give to the same a raised
appearance.

an Order of the Lord Chancellor, by the said Frank Wirth in the Great Seal
Patent Office on the 28th August 1876.

on-the-Main, in the Empire of Germany. "IMPROVEMENTS IN WOVEN FABRICS."
A communication from Jules Carrey, Manufacturer, residing at Mulhausen
(Alsatia).
My Invention consists in an improvement in woven fabrics, by which articles
woven according to the said Invention and afterwards pattern printed present the
appearance of a pattern woven into the substance and not printed on the surface of
such fabrics. This object is accomplished by having the warp or weft threads
permanently dyed so as to resist the after process of printing, or by running a
second fast dyed thread by the side of the ordinary warp or weft threads, the
permanently dyed threads being distinctly visible after the printing process is over,
give to each mesh a distinct and separate appearance, and a raised appearance to
the other threads, the pattern thus is apparently woven into the tissue.
The characteristic novelty of this Invention, as above specified, is used to give
effect to patterns and designs printed on woven substances, so as to give the said
patterns or designs the appearance of being woven or worked into the tissue, this
effect being produced by having the threads running in one direction (either the
weft or warp) permanently dyed, or by introducing by the side of the weft or warp
a second thread permanently dyed. These fast dyed threads are not affected by
the printing, and lying by the side of the thread which take the pattern they give
to the same a raised appearance.
In witness whereof, I, the said Frank Wirth, have hereunto set my hand and
seal, this Twenty-third day of June, in the year of our Lord One thousand
eight hundred and seventy-six.
FRANK WIRTH. (L.S.)
