IMPROVEMENTS IN PRINTING, AND IN ENGRAVING OR TAKING IMPRESSIONS FROM FABRICS OR MATERIALS UPON METALS, FOR THE PURPOSE OF PRINTING OR EMBOSSING."
Year: 1880

page_text: LETTERS PATENT to Joseph Julius Sachs, of Manchester, in the County of
Lancaster, for an Invention of "IMPROVEMENTS IN PRINTING, AND IN ENGRAVING
OR TAKING IMPRESSIONS FROM FABRICS OR MATERIALS UPON METALS, FOR THE
PURPOSE OF PRINTING OR EMBOSSING."
PROVISIONAL SPECIFICATION left by the said Joseph Julius Sachs at the
Office of the Commissioners of Patents on the 11th February 1880.
JOSEPH JULIUS SACHS, of Manchester, in the County of Lancaster. "IMPROVE
MENTS IN PRINTING, AND IN ENGRAVING OR TAKING IMPRESSIONS FROM FABRICS
OR MATERIALS UPON METALS, FOR THE PURPOSE OF PRINTING OR EMBOSSING."
My Invention relates to improvements in printing, and in engraving or taking
impressions from any open or figured woven or other fabric or material, such as
paper or other substance, upon copper or other metal, for the purpose of printing or
embossing.
In carrying out my Invention as applied, for example, to the engraving or taking
impressions from lace upon metals, I take a piece of lace, and after coating it with
a substance, such, for example, as a solution of asphaltum, which will make it resist
the action of the solution contained in an etching bath, I cause it to adhere to a
copper roller; I then immerse the roller covered with the lace in an ordinary
etching bath, or in an etching bath to which is connected an electric battery, the
bath being filled with an etching solution. Upon immersion, and when necessary
applying the current of electricity, the exposed parts of the roller are eaten away
to any desired depth, according to the nature of the printing to which the roller is
intended to be applied; the lace is then removed, and the roller cleaned and
prepared for printing with in the ordinary manner.
By this means I obtain a result which for holding the colour when printing is
superior to that which can be obtained by the ordinary means. I find it advan-
tageous to maintain the roller in motion during the time that it is in the bath. In
order to produce an effect the counterpart of that which is obtained by the mode of
operation hereinbefore described the roller is covered between the interstices of

page_text: the threads of the lace or other material with a resist; the pattern of laco or
other material is then removed, and the roller is placed in the bath, as before
described.
Although I have given these examples as types of the application of my
Invention, it is obvious that the Invention is equally applicable for obtaining the
same engraved or embossed effect, that is to say, the representation of lace or other
open, figured, woven or other fabric or material from the fabric or material itself
upon any metal, and upon any form, whether in the shape of a roller or otherwise.
The fabrics or materials may be used for obtaining a pattern upon a roller, plate,
or other substance or surface which may have been previously prepared by ruling 1
and varnishing.

JOSEPH JULIUS SACHS, of Manchester, in the County of Lancaster. "IMPROVE-

My said Invention relates to improvements in printing, and in engraving or
taking impressions from any open or figured woven or other fabric or material,
such as paper or other substance upon copper or other metal, for the purpose of
printing or embossing.
In carrying out my said Invention as applied, for example, to the engraving or
taking impressions from lace upon metals, I tako a piece of lace, and after coating
it with a substance, such, for example, as a solution of asphaltum, which will make
it resist the action of the solution contained in an etching bath, I cause it to adhere
to a copper roller; I then immerse the roller covered with the lace in an ordinary
etching bath, or in an etching bath to which is connected an electric battery, the
bath being filled with an etching solution, and I, by preference, maintain the roller
in motion during the time that it is in the bath. Upon immersion, and when
necessary applying the current of electricity, the exposed parts of the roller are
caten away to any desired depth, according to the nature of the printing to which
the roller is intended to be applied; the lace is then removed, and the roller is used
for printing, stamping, or embossing in the ordinary manner.
By this means I obtain a result which for holding the colour when printing
is superior to that which can be obtained by the ordinary means. In order to
produce an effect the counterpart of that which is obtained by this method the
roller is covered between the interstices of the threads of the laco or other material
with a resist; the pattern of lace or other material is then removed, and the roller
is placed in the bath, as before described.
Although I have given these examples as types of the application of my said
Invention, it is obvious that the Invention is equally applicable for obtaining the
same engraved or embossed effect, that is to say, the representation of lace or other
open, figured, woven or other fabric or material from the fabric or material
itself, upon any metal, and upon any forme, whether in the shape of a roller or
otherwise.
The fabrics or materials may be used for obtaining a pattern upon a roller, plate,
or other substance or surface which may have been previously prepared by ruling
and varnishing.
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 would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is,
The improvements in printing, and in engraving or taking impressions from
fabrics or materials upon metals, for the purpose of printing or embossing,
substantially as hereinbefore described.
In witness whereof, I, the said Joseph Julius Sachs, have to this my
Specification set my hand and seal, this Fourteenth day of July, One
