Improvements in Decorating Articles of Enamelled Sheet or Cast
Steel, Iron, or other Metal, suitable for Street Nomenclature,
Enamelled Signs, and other Analogous Purposes.
I VINCENZ GECMEN of the Bubua Iron Works, Prague in the Empire of Austria
Manufacturer do hereby declare the nature of my said 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 a new process for decorating articles of enamelled sheet or
cast iron steel or other metals and has for its object to effect such decoration or
ornamentation in a cheaper manner than has been hitherto practised with the aid of
or by any of the well known methods such as painting or printing with fused colors
transferring or the like. The articles manufactured according to this invention
surpass the products hitherto brought into the market both as regards durability and
beauty.
The new process is substantially carried out as follows:-A white or colored vitreous
or glazing substance or covering mass is first applied in the usual well known manner
upon the articles of cast or sheet iron or steel which have been previously provided with
a suitable ground and burnt. The articles thus treated are burnt again, the material
applied thereto forming the back ground for the decorations hereafter to be formed
thercon. The first covering mass is then coated with a second vitreous or glazing
covering mass which may be white or colored according to requirements. A portion
of this second covering mass is removed in a dry or wet state by carefully scratching
cutting out engraving or delineating in any suitable manner by means of contour lines
until the first coating mass thereby exposed represents the required design or pattern.
The articles thus treated are now burnt in a muffle furnace after which they may be
brought into the market as finished goods or they may be provided with still richer
decorations or ornamentations. The design or pattern produced in this manner appears
slightly in intaglio. Should it be preferred that the said pattern or design had a raised
or embossed form the whole of the substance which does not serve in the formation of
the design or pattern is removed in a dry or wet state from the second covering mass
so that the first glazing or vitreous covering mass will form the ground while tho
second glazing will produce the design or pattern. In these two processes herein-
before described the vitreous or glazing material for the covering and then that for
the ground are transferred. The two processes aforesaid are not only applicable for
decorating or ornamenting purposes to articles or wares of enamelled sheet or cast
iron, steel or other metals but also to the metal plates used for writing thereon the
name of streets railway stations, the numbers of houses and the like.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what I
claim is
-
1st. The improved process for decorating or ornamenting articles or wares of
enamelled sheet or cast iron steel or other metal characterised by first covering and
then incrustating by burning in the whole surface thereof the glazing or vitreous
substance of the design or pattern required and laying over that the vitreous or
glazing substance forming the ground a portion of the lower vitreous substance being
laid bare by scratching cutting out engraving by contour lines or the like in the upper
covering whilst in a dry or wet state so as to form the design or pattern this
treatment being followed by a burning operation substantially as hereinbefore
described.
2nd. The improved process last previously claimed modified to such an extent that

page_text: the glazing or vitreous substance of the ground is laid over and burnt in the whole
surface of the article under treatment whereupon the glazing or vitreous substance of
the design or pattern is subsequently laid from which the whole of the substance which
does not serve to form the design or pattern is afterwards removed in a dry or wet
state substantially as hereinbeforo described.
