My said Invention relates to an improved method of producing or preparing
roller surfaces for printing stamping or embossing whereby the ordinary process
of engraving upon rollers is dispensed with.
According to my said Invention I take a photograph made upon chrome gelatine
paper or equivalent material and transfer the same to the roller by pressure or
otherwise I then remove the paper or, material leaving the pattern or design upon
the chrome gelatine or its equivalent on the roller and the soluble parts are then
removed by washing or otherwise. I next cover the entire surface of the roller
with a solution of bitumen asphaltum or similar material in benzine or turpentine
or their equivalent and place the roller in a metallic or etching solution and I.
preferably connect the roller to a galvanic battery or magneto-electric or dynamo
electric machine and cause the roller to revolve. It is necessary that the chrome
gelatine altered by the action of light and adhering to the metallic surface should
be caused to loosen its hold upon the metallic surface with its covering of asphalte
thereby exposing those parts of the roller surface to the influence of the metallic,
or etching solution.
This result is obtained by either first introducing the roller into a solution'
containing free acid such for example as hydrochloric acid or by the addition of
acid to the metallic or etching solution.
By the means herein before described I obtain the counterpart of the pattern or
design previously transferred to the roller and the roller so prepared after having
been cleaned is ready for printing stamping or embossing Under the term rollers
used in this my Specification I include mills for embossing printing rollers.
"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 or embossing substan-
tially in the manner hereinbefore described.

page_text: LETTERS PATENT to Joseph Julius Sachs, of Manchester, in the County of
Lancaster, for an Invention of "IMPROVEMENTS IN THE PRODUCTION of

PROVISIONAL SPECIFICATION left by the said Joseph Julius Sachs at the
Office of the Commissioners of Patents on the 10th May 1880.
"IMPROVE-
JOSEPH JULIUS SACHS, of Manchester, in the County of Lancaster.
MENTS IN THE PRODUCTION OF ROLLER SURFACES FOR PRINTING, STAMPING, OR
EMBOSSING."
My Invention relates to an improved method of producing roller surfaces for
printing, stamping, or embossing, whereby the ordinary process of engraving upon
rollers is dispensed with.
According to one mode of carrying out my Invention I cover the roller with
chrome gelatine or equivalent material, and I take a pattern or design produced by
photography or otherwise upon translucent paper, or upon glass made of a curved
shape, or upon any other suitable translucent materials, or a pattern or design
upon other paper or material produced with oil colors or translucent agents, and
place such pattern or design of paper, glass, or other material round the roller and
exposed to the action of electric or other light, the roller being caused to revolve so
as to present each portion in succession to the action of the light.
The parts of the chrome gelatine upon which the light acts are rendered
insoluble, whilst the other parts not acted upon by the light remain soluble, and
may be washed away or otherwise removed if required, after which I apply to the
surface a solution of alcoholic or other perchloride of iron, or an equivalent agent,
which acts as a resistant; or I may apply the perchloride of iron or its equivalent
to the surface without the process of washing, whereby the insoluble parts of the
chrome gelatine are rendered resistant, and the soluble parts are etched, the roller
in either case being obtained in a condition for use as a printing, stamping, or
embossing surface.
According to another mode of carrying out my Invention I take a photograph
made upon chrome gelatine paper or equivalent material and transfer the saine to

page_text: the roller by pressure or otherwise. I then remove the paper or material, leaving
the pattern or design in the chrome gelatine or its equivalent upon the roller, and
the soluble parts are then removed by washing or otherwise. I next cover the
entire surface of the roller with a solution in benzine or turpentine, or their
equivalent, of bitumen, asphalte, or similar material, and place the roller in a
metallic or etching solution, and connect the roller to a galvanic battery or magneto
electric or dynamo electric machine by preference, causing the roller to revolve.
The chrome gelatine and the bitumen or asphalte, or its equivalent, upon the same
are thus removed, and the parts etched by the galvanic or electric action, leaving
the bitumen, or asphalte, or its equivalent adhering to the metal of the roller. I
thus obtain the counterpart of the pattern or design previously transferred to the
roller, and the roller so prepared after having been cleaned is ready for printing,
stamping, or embossing.

"IMPROVE-
MENTS IN THE PRODUCTION OF ROLLER SURFACES FOR PRINTING, STAMPING, OR
EMBOSSING."
My said Invention relates to improved methods of producing or preparing roller
surfaces for printing, stamping, or embossing, whereby the ordinary process of
engraving upon rollers is dispensed with.
According to one mode of carrying out my said Invention I cover the roller with
chrome-gelatine or an equivalent material, and I take a pattern or design produced
by photography or otherwise upon translucent paper, or upon glass made of a
circular or curved shape, or upon any other suitable translucent materials, or a
pattern or design upon other paper or material produced with oil or other suitable
colours or translucent agents, and place such pattern or design of paper, glass, or
other material round the roller and expose it to the action of electric or other light,
the roller being caused to revolve so as to present each portion in succession to the
action of the light. The parts of the chrome-gelatine or equivalent substances
upon which the light acts in a similar manner are rendered insoluble, whilst the
other parts not acted upon by the light remain soluble, and may be washed away
or otherwise removed if required, after which I apply to the surface an alcobolic or
other suitable solution of perchloride of iron or similar acting agent, or I may
apply the perchloride of iron or its equivalent to the surface without the process of
washing. The insoluble parts of the chrome gelatine act as a resistant, and the
soluble parts are etched, and the roller may then be prepared for use as a printing,
stamping, or embossing surface in the ordinary manner.
According to another mode of carrying out my said Invention I take a photograph
made upon chrome gelatine paper or equivalent material and transfer the same to
the roller by pressure or otherwise. I then remove the paper or material, leaving
the pattern or design upon the chrome gelatine or its equivalent on the roller, and
the soluble parts are then removed by washing or otherwise. I next cover the
entire surface of the roller with a solution of bitumen, asphaltum, or similar
material in benzine, or turpentine, or their equivalent, and place the roller in a
metallic or etching solution, and I preferably connect the roller to a galvanic
battery or magneto-electric or dynamo-electric machine, and cause the roller to
revolve. It is necessary that the chrome gelatine altered by the action of light
and adhering to the metallic surface should be caused to loosen its hold upon the
metallic surface with its covering of asphalte, thereby exposing those parts of the
roller surface to the influence of the metallic or etching solution.
This résult is obtained by either first introducing the roller into a solution
containing free acid, such, for example, as hydrochloric acid, or by the addition of
acid to the metallic or etching solution.
By the means hereinbefore described I obtain the counterpart of the pattern or
design previously transferred to the roller, and the roller so prepared after having
been cleaned is ready for printing, stamping, or embossing. Under the term
rollers used in this my Specification I include mills for embossing printing
rollers.
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,

page_text: 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, or embossing, substantially
in the manner hereinbefore described.
In witness whereof, I, the said Joseph Julius Sachs, have to this my Specifi-
cation set my hand and seal, this Fourth day of November, One thousand
eight hundred and eighty.
