And in order that the effect of the said Disclaimer and Memorandum of
Alteration may be clearly understood I annex hereto a copy of the said Specifi-
cation as it will appear when so amended the Preamble and testing Clause being
omitted
In carrying out my said Invention I proceed as follows I first take a roller and
coat it with a varnish or layer of some substance or material which will resist the
action of the chemicals in an etching bath or metallic or galvanic bath-When this
resist is dry I paint over the surface with some sticky substance as for instance
solution of gums, gelatine, starch paste or the like in water or other solvent
and while this sticky substance is wet I lay round the roller the design which
consists of any open fabric.
Suppose for instance I take a piece of lace I put it round the roller and it
adheres to the roller the substance super imposed on the resist causing it to do so
the lace edges are sewn together previously thus forming as it were a tube which
I can then slip over the roller or I can place the lace or pattern on the roller and
cause it to adhere afterwards by means of the sticky substance mentioned without
first covering the surface with the sticky substance and in that case I cover it
afterwards with the sticky substance which soaks through and causes the pattern
to adhere to the roller-While this sticky solution is still wet I can adjust the
pattern in any way the ends being sewn together as before mentioned the repeat
is provided for in the sewing-The two ends joined or sewn together so as to form
a repeating pattern-The moisture in the gum or sticky substance causes the
to contract and clasp the roller tightly so that when the pattern
pattern fits the roller moderately well when dry the addition of water only, or of
A

page_text: acid or alkaline or other liquor is sometimes sufficient to hold it in its place during
the subsequent operation especially if the pattern be kept damp or moist or in
some cases the pattern can be fixed on the roller in a dry state and kept dry
throughout the process but I prefer to use the wet process as it produces better
results-
When gum or sticky substance has been used as mentioned the roller with the
lace or pattern adhering is dried and when dried is ready for cleaning out-
This can be done by hand using an instrument pointed by preference like a
chisel with which the gum or equivalent and the resist, beneath shewing through
the interstices of the pattern, are removed and are scraped away leaving the bare
copper metal or other surface which is subsequently acted on só as to be etched by
an etching liquid or metal can be deposited thereon by galvanic or other means-
This cleaning can also be effected by means of the sandblast or similar con-
trivance where metallic or other hard particles are substituted for sand and this is
the most expeditious manner of doing it or the exposed parts may be cleaned of
the resist by a brush the bristles of which are stiff or composed of wire which
brush scrapes off or detaches the resist through the interstices of the pattern but
leaves the covered parts untouched
After cleaning the roller is ready for etching but to prevent error I prefer to
take off the pattern first by soaking it in water or acid or other solvent for the
sticky substance used and then (cutting the lace or pattern which has been joined
before putting on the roller) the pattern can be easily removed and the surface
inspected and any faults rectified before etching-The etching is or may be carried
out as stated in the Specification of my previous Patent N° 266 dated the twenty
first day of January in the year of our Lord One thousand eight hundred and
eighty one with or without the aid of an electric current-
To produce the reverse effect instead of etching the roller prepared in the above
manner I deposit copper or other metal on the exposed parts by electro deposition-
The metal depositing on the bare parts whilst the parts covered with resist remain
unaltered-
To produce a rougher surface in the engraving the better to hold colour I place
the roller after being etched or after the metal has been deposited on it (in the
first case the adbering resist may or may not be removed in the latter case it must
be removed) in "the electrotyping" bath and deposit a thin film of metal over the
surface of the roller or engraving-The roller or surface is then polished the rough
metallic film is thus removed from the outstanding part but remains at the bottom
of the Engraving forming a rough surface which is admirably adapted for holding
colour.
To produce for example say pin engraving I take a mill covered with pin
engraving and run it over the roller before commencing the process and thus the
whole surface is covered with this engraving-I then proceed as before and when
finished I have as result a roller the outstanding parts of which print the pin or
other engraving while the sunken parts print a solid pattern thus giving beautiful
effects This is especially useful for printing oil colors as for instance for printing
on oil cloth
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 production of roller surfaces for printing stamping embossing and other
useful and ornamental purposes as herein before described-
substantially
In witness whereof I the said Joseph Julius Sachs have hereunto set my hand
and seal this twentieth day of November One thousand eight hundred and eighty

In carrying out my said Invention I proceed as follows. I first prepare the
surface to be engraved or etched and which surface may consist of a plate or
roller or other form of surface. Taking for example a roller I first coat it with a
varnish or layer of some substance which will resist the action of the chemicals in
an etching bath or metallic bath. When this resist is dry I paint over the surface
with some sticky substance as for instance solution of gums, gelatine, starch, paste
or the like in water or other solvent and while this sticky substance is wet I lay
round the roller or on the surface the design which may consist of any open or
closed fabric or material. Suppose for instance I take a piece of lace I wrap it
round the roller and it adheres to the roller the substance superimposed on the
resist causing it to do so. The lace is thus attached to the roller and I can now
adjust the edges of the lace so that the pattern repeats itself perfectly round the
roller. Or the lace edges may be sewn together previously thus forming as it
were a tube which I can then slip over the roller or I can place the lace or pattern
on the roller and cause it to adhere, afterwards by means of the sticky substance
mentioned, without first covering the surface with the sticky substance and in that
case I cover it afterwards with the sticky substance which soaks through and
causes the pattern to adhere to the roller or surface. While this sticky solution is
still wet I can adjust the pattern in any way and arrange it so that it shall repeat
itself round the roller or if the ends are sewn together as before mentioned the
repeat is provided for in the sewing. In the latter case when lace or any woven
or worked fabric is used and the two ends joined or sewn together so as to form a

page_text: repeating pattern and this then slipped over the roller. The moisture in the gum
or sticky substance causes the pattern to contract and clasp the roller tight so that
when the pattern fits the roller moderately well when dry the addition of water
only or of some acid or alkaline liquor or other liquor is sometimes sufficient to
hold it in its place during the subsequent operation especially if the pattern be
kept damp or moist.
When gum or sticky substance has been used as mentioned the roller or
surface with the lace or pattern adhering is dried and when dried is ready for
cleaning out.
This can be done by hand using an instrument pointed by preference like a
chisel and with which the gum or equivalent and the resist beneath shewing
through the interstices of the pattern are removed and are scraped away leaving
the bare copper, metal or other surface which is thus subsequently affected and
etched by the etching liquid. This cleaning can also be effected by means of the
sand blast or similar contrivance where metallic or other hard particles are
substituted for sand and this is the most expeditious manner of doing it, or the
expose and parts may be cleaned of the resist by a brush the bristles of which are
stiff or composed of wire and which brush scrapes off or detaches the resist through
the interstices of the pattern but leaving the covered parts untouched.
After cleaning out the roller is ready for etching but to prevent error I prefer to
take off the pattern first by soaking it in water or acid or other solvent for the
sticky substance used and then (cutting the lace or pattern if it has been joined
before putting on the roller) the pattern can be easily removed and the surface
inspected and any faults rectified before etching. The etching is carried out as
stated in my previous patent mentioned with or without the aid of an electric
current.
To produce the reverse effect instead of etching the prepared roller or surface
prepared in the above manner I propose to deposit copper or other metal on the
exposed bare parts by electro deposition. The metal depositing on the bare parts
whilst the parts covered with resist remain unaltered.
To produce a roughened surface in the engraving to hold colour I place the
roller or surface after being etched or after the metal has been deposited on it, (In
the first case the adhering resist may or may not be removed in the latter case it
must be removed) in the electrotyping bath and deposit a thin film of metal over
the surface of the roller or surface. The roller or surface is then polished, the
rough metallic film is thus removed from the outstanding part but remains at the
bottom of the engraving forming a rough surface which holds colour admirably.
To produce for example say pin engraving I take a mill covered with pin
engraving and run it over the roller or surface before commencing the process and
thus the whole surface is covered with this engraving. I then proceed as before
and when finished I have as result a roller or surface the outstanding part of
which print the pin or other engraving while the sunk parts print a solid pattern
thus giving beautiful effects. This is especially useful for printing oil colors as for
instance printing on oil cloth.

JOSEPH JULIUS SACH's of Sunbury in the County of Middlesex
"IMPROVEMENTS
IN THE PRODUCTION OF SURFACES FOR PRINTING STAMPING AND EMBOSSING.'
"
In carrying out my said Invention I proceed as follows-I first prepare the
surface to be engraved or etched which surface may consist of a plate or roller or
other form of surface. Taking for example a roller I first coat it with a varnish
or layer of some substance or material which will resist the action of the chemicals
in an etching bath or metallic or galvanic bath-When this resist is dry I paint
over the surface with some sticky substance as, for instance solution of gums,
gelatine, starch, paste, or the like in water or other solvent and while this sticky
substance is wet I lay round the roller or on the surface the design which may
consist of any open or closed fabric or material or substance for instance Gelatine,
Rubber Cloth paper and the like.
When using designs cut or stamped in India rubber or similar material these can
be stretched round the roller which does not even need varnishing in that case as
the rubber clings so tightly to the roller that the etching solution or galvanic bath
solution cannot penetrate underneath the pattern but only affects the exposed
surface. Or the roller can be varnished and the pattern fixed on by its own
elasticity and proceeded with as hereinafter described with or without removing
the design before the etohing or depositing.
Suppose for instance I take a piece of lace, I wrap it round the roller and it
adheres to the roller the substance super-imposed on the resist causing it to do so
The lace is thus attached to the roller and I can now adjust the edges of the lace
so that the pattern repeats itself perfectly round the roller-Or the lace edges may
be sewn together previously thus forming as it were a tube which I can then slip
over the roller or I can place the lace or pattern on the roller and cause it to
adhere, afterwards by means of the sticky substance mentioned without first
covering the surface with the sticky substance and in that case 1 cover it afterwards
with the sticky substance which soaks through and causes the pattern to adhere to
the roller or surface. While this sticky solution is still wet I can adjust the
pattern in any way and arrange it so that it shall repeat itself round the roller or
if the ends be sewn together as before mentioned the repeat is provided for in the
sewing. In the latter case when lace or any woven or worked fabric is used and
the two ends joined or sewn together so as to form a repeating pattern this is then
slipped over the roller. The moisture in the gum or sticky substance causes the
pattern to contract and clasp the roller tightly so that when the pattern fits the
roller moderately well when dry the addition of water only, or of acid or alkaline
or other liquor is sometimes sufficient to hold it in its place, during the subsequent
operation, especially if the pattern be kept damp or moist or in some cases the
pattern can be fixed on the roller or surface in a dry state and kept dry
throughout the process but I prefer to use the wet process as it produces better
results.
When gum or sticky substance has been used as mentioned, the roller or
surface with the lace or pattern adhering is dried, and when dried is ready for
cleaning out.
This can be done by hand using an instrument, pointed by preference like a
chisel, with which the gum or equivalent and the resist beneath shewing through
the interstices of the pattern, are removed and are scraped away leaving the bare

page_text: copper metal or other surface, which is subsequently acted on so as to be etched
by an etching liquid or metal can be deposited thereon by galvanic or other
means.
"
This cleaning can also be effected by means of the sandblast or similar
contrivance where metallic or other hard particles are substituted for sand, and
this is the most expeditious manner of doing it, or the exposed parts may be
cleaned of the resist by a brush the bristles of which are stiff, or composed of
wire, which brush scrapes off or detaches the resist, through the interstices of the
pattern, but leaves the covered parts untouched.
After cleaning the roller is ready for etching but to prevent error, I prefer to
take off the pattern first, by soaking it in water or acid or other solvent for the
sticky substance used, and then, (cutting the lace or pattern if it has been joined
before putting on the roller) the pattern can be easily removed and the surface
inspected, and any faults rectified before etching. The etching is or may be carried
out as stated in the Specification of my previous Patent No. 266 dated the 21st
day of January A.D. 1881. with or without the aid of an electric current.
To produce the reverse effect instead of etching the roller or surface prepared in
the above manner I deposit copper or other metal on the exposed bare parts by
electro deposition-The metal depositing on the bare parts whilst the parts covered
with resist remain unaltered.
To produce a rougher surface in the engraving the better to hold colour I place
the roller or surface after being etched or after the metal has been deposited on it;
(in the first case the adhering resist may or may not be removed; in the latter
case it must be removed) in "the electrotyping bath and deposit a thin film of
metal over the surface of the roller or engraving-The roller or surface is then
polished the rough metallic film is thus removed from the outstanding part but
remains at the bottom of the Engraving forming a rough surface which is admirably
adapted for holding colour.

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 production of surfaces for printing stamping embossing and other useful
and ornamental purposes substantially as herein before described.
In witness whereof I the said Joseph Julius Sachs bave to this my
Specification set my hand and seal this sixth day of September-One
thousand eight hundred and eighty two.
