Improved Process or Means for Producing Designs, Devices, and the
like upon Material for Reproduction in Castings, or by the Zinco,
Electro Deposit, or other known Processes.
I, JOHNSTON STEPHEN, of Woolmet House, Liberton, Midlothian, N.B., Journalist
do hereby declare the nature of this invention to be as follows:
-
This invention relates to improved process or means for producing designs,
devices, and the like upon material for reproduction in castings, or by the zinco,
electro-deposit, or other known processes.
To carry this invention into practice, I take, say, a sheet of thin copper or
brass, and by a stylus or other suitable instrument, I indent it in the desired
manner by drawing the instrument over or into it with more or less pressure as
to leave the outline of figure device or design, and I fill in the outline either from
the same or from the other face in the same manner.
Certain parts of the figure, device, or design may be then rubbed from the
reverse side, and in some cases from the same side also to produce rotundity
depressions, curvatures, or protuberances and also flatness.
The plate thus prepared, say, by an artist is then ready for a casting from
either of its faces, or a reproduction can be made from both faces by the zinco,
electro deposit, or other known process and used for printing, stamping and
transferring to metal, paper, or other material such as plastic bodies by impression
or compression..
For reproducing metal goods, or goods of other comparatively hard substances
upper and lower castings would serve as the male and female dies of a press, or
may be used separately for reproductions on surfaces such as in rubber, wood, or
other pulp or mastic, or for producing impressions in or on book covers, cardboard,
and like boxes, on or in paper sheets and paper goods, or anything or material
which is capable of being printed or impressed, the effect being that of the first
or artist's work transferred directly to the article or material which has to be
brought before the public, and if desired a combination of figures or indications
partly in relief and partly in intaglio can be prepared as desired.

I, JOHNSTON STEPHEN, of Woolmet House, Liberton, Midlothian, N.B., Journalist.
do hereby declare the nature of this invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:
This invention relates to improved process or means for producing designs,
devices, and the like upon material for reproduction in castings, or by the zinco,
electro-deposit or other known processes.
To carry this invention into practice, I take, say, a sheet of thin copper or
brass, and by a stylus or other suitable instrument, which may be a lead pencil I
indent it in the desired manner by drawing the instrument over or into it with
more or less pressure as to leave the outline of figure, device, or design, and I fill
in the outline either from the same or from the other face in the same manner.
Certain parts of the figure, device, or design may be then rubbed from the
reverse side, and in some cases from the same side also to produce rotundity
depressions, curvatures, or protuberances, and also flatness.
The plate thus prepared, say, by an artist, is then ready for a casting from
either of its faces, or a reproduction can be made from both faces by the zinco,
electro-deposit, or other known process, or the thin metal so treated by the
artist may be backed with a material such as a quick setting cement or plaster,
or preferably by a metal more fusible than itself, or by having metal electro-
lytically deposited on its back, in such manner as itself to become an efficient and
useful die or stamp, and used for printing, stamping, and transferring to metal,
paper, or other material, such as plastic bodies by impression or compression.
press,
For reproducing metal goods, or goods of other comparatively hard substances,
the upper and lower castings would serve as the male and female dies of
or may be used separately for reproductions on surfaces, such as in rubber, wood,
or other pulp. or mastic, or for producing impressions in or on book covers, card-
board, and like boxes on or in paper sheets and paper goods, or any thing or
material which is capable of being printed or impressed, the effect being that of
the first or artists' work transferred directly to the article or material which has
to be brought before the public, and if desired a combination of figures or indica-
tions partly in relief and partly in intaglio can be prepared.
When I have obtained the first metal embossed or sunk effect by drawing and
modelling upon a thin sheet of metal in the manner described, I may make a
wax or stearine, or other cast and may work upon such cast with a graver or
other tool or tools, for the production of greater sharpness, and this wax or
stearine or other cast so worked upon may become the material upon which the
electrotype is formed, or the pattern from which in the usual way, casts in fusible
metal or other material are taken.
It is obvious that the invention may be applied in many ways, as for example,
for the production of white plaster casts in relief, said plaster casts being photo-
graphed and half-tone blocks or toned lithographic surfaces being produced
therefrom.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. The employment of thin plates or sheets of ductile metal as means for the

page_text: production of devices and artistic intaglio or relief impressions by direct action
of a stylus or the like, from which plates or sheets, castings or reproductions by
the zinco, electro deposit, or other known methods for direct printing, embossing,
or blocking, or equivalent purposes can be obtained, or for the formation of pulp,
mastic, or other matrix dies or stamp dies, from which castings or the like may
be prepared for printing, embossing, or blocking purposes, as set forth.
2. For the purposes herein before described and for analogous purposes the
methods herein before described, that is to say, for the purposes of making stamps
and dies, the use of metal sheets so plastic and impressible as to be mouldable
with slight tools or lead pencils, and with pressure very little greater than that
which is required in pencil drawing, so rendering the production of a metal die
or stamp easily within the powers of the artist without intervention of any
artificer, and thereby securing directness and an autographic quality hitherto
absolutely unattained.
