FABRICS." [A communication from abroad by Georg Grossheim, of Elberfeld,
Germany.]
This Invention, as communicated to me from abroad, consists of obtaining
imitations of marbles and such like veined and grained surfaces on paper, oil cloth,
and other fabrics.
The veins or grains are traced either mechanically or chemically; the hollowed
or engraved parts are then filled with paint of suitable colour, and the marble,
wood, or other surface thus treated is used as a medium for printing impressions
from.

And in order that this said Invention communicated to me may be properly
understood, and, if required, carried into practical effect, I will now proceed to
describe more particularly the exact manner or process by which it is proposed to
carry out these said improvements, that is to say,—
Hitherto the imitations of marble or other natural mineral materials have been
executed by the artist's hand, guided by his taste and his knowledge of the mineral
or other substance he desires to imitate, therefore these imitations are more or less
inaccurate.
Now in order to reproduce the true resemblance of the mineral substance to be
copied, and to have the power of reproducing these exact copies the Inventor
proceeds as follows:-A block, slab, or piece of the substance to be copied or imitated
is smoothed, and, if necessary, polished; the natural veins or other markings are
then incised or sunk in the surface of the block, slab, or cylinder.
This portion of the process of this Invention may be carried out in two ways;
the block or other surface to be copied may be etched or incised either by the action
of acids or other chemical means, or it may be engraved so as to produce a facsimile
of the natural specimen selected for reproduction; thus, if white-veined marble is
to be reproduced, either in the ordinary manner of printing or as in the cylinder
process of the paper-hanging manufacture.
The block, slab, or cylinder is incised, etched, or engraved so as to imitate exactly
the original or natural specimen; and where several colours are required to repro-
duce a facsimile of the original marble or other surface, then a corresponding number
of blocks or cylinders must be so etched or otherwise incised, and these blocks or
cylinders may be employed as a means of transfer to stone, metal, wood, or other
material suitable for printing purposes. In this way an accurate reproduction of
selected natural samples may be obtained and multiplied to any extent.
Having now described and ascertained the nature of the said Invention communi-
cated to me, I desire it to be understood that I do not confine myself to the precise
details of the process or processes herein-before referred to, as the same may be
varied without departing from the essential features of this Invention, but what I
consider to be novel, and therefore claim under the herein-before in part recited
Letters Patent, is,―
First. The method or system of producing from the natural material or substance
a facsimile applicable to the ordinary processes of printing or otherwise transferring
such designs, as herein-before described.
Secondly. The particular method of obtaining exact representations of marbles
and other natural ornamental surfaces by means of etching, engraving, or otherwise
incising such natural surfaces, and afterwards applying these blocks, slabs, or

page_text: cylinders to the purposes of printing or other method of reproduction, as herein-
before described.
In witness whereof, I, the said Reinhart Lowen, have hereunto set my hand
and seal, this Thirtieth day of August, in the year of our Lord One
thousand eight hundred and seventy-eight.
