AN IMPROVED METHOD OF DECORATING TIN AND OTHER METAL SURFACES
Year: 1878

page_text: LETTERS PATENT to Leon Quentin Brin, of the Borough, in the County of
Surrey, for the Invention of "AN IMPROVED METHOD OF DECORATING TIN
AND OTHER METAL SURFACES."
Scaled the 17th December 1878, and dated the 3rd July 1878.
PROVISIONAL SPECIFICATION left by the said Leon Quentin Brin at the
Office of the Commissioners of Patents on the 3rd July 1878.
LEON QUENTIN BRIN, of the Borough, in the County of Surrey.
PROVED METHOD OF DECORATING TIN AND OTHER METAL SURFACES."
"AN IM.
In the Specification of my Patent dated 28th Jany., 1878, No. 360, for "Im-
provements in Decorating Surfaces Coated with Tin and other Metals, and in
Machinery therefor," I have described several methods of imparting a crystallized
surface or surfaces to various metals for the purposes of decoration.
My present Invention refers to an improved method of writing, printing, or
drawing on or otherwise decorating crystalized or crystal-like surfaces, in the
manner substantially herein-after described.
I take the metal with the surface crystalized, but before it has been dipped in
the acid bath, say, as described in the Provisional Specification of my Patent
aforesaid, and as soon as it is cold I write, print, or draw on or otherwise decorate
the surface by means of a brush, type, or other convenient means with a drying
oil or varnish of any kind, or grease, or resinous fat, or other transparent medium
capable of resisting the action of the acid baths herein-after mentioned.
Thus printed the plates are submitted to the action of a bath, which will vary
according to the nature of the metals; thus, for tinned iron the bath is or may be
composed as follows:-

page_text: A bath suitable for sheets of galvanized iron consists of,-
Sea salt
Distilled water
Oxalic acid
-
10 parts.
90 parts.
10 parts.
A bath suitable for sheets of lead or terne is hydrochloric acid decomposed by 5
zinc sheets until saturation is completed.
As soon as the desired effect is obtained by immersion in the bath, the plates are
transferred to another bath, and there well washed in pure water and subsequently
dried.

PROVED METHOD OF DECORATING TIN AND OTHER METAL SURFACES."
"AN IM-
In the Specification of my Patent dated 28th January 1878, No. 360, for
"Improvements in Decorating Surfaces Coated with Tin and other Metals, and in
Machinery therefor," I have described several methods of imparting strongly
marked and decorative crystalized surface or surfaces to various metals for the
purposes of decoration.
My present Invention refers to an improved method of writing, printing, or
drawing on or otherwise decorating or marking crystalized or crystal-like surfaces,
in the manner substantially herein-after described.
I take the metal with the surface crystalized in any known manner, and
artificially produced or otherwise; thus, for instance, a lead surface simply exposed
to the oxidising action of the air will, when microscopically examined, exhibit a
crystal-like surface, although to the naked eye only a dull even surface.
As an example of artificially produced, but not strongly marked, crystal surfaces
which are to be decorated according to this present Invention, I may mention such
as are produced in the manner described in the Specification of my aforesaid pre-
vious Patent, in the condition in which the metal surface is before it has been dipped
in the acid bath therein named, and as soon as it is cold.
According to this Invention I write, print, draw, or otherwise mark or decorate
such as any crystalized or crystal-like surface by means of a brush, type, stencil,
engraved stone, moulded india-rubber, "decalcomanie," or other convenient means
with a drying oil or varnish of any kind, or grease, or resinous fat, or other
transparent or opaque medium capable of resisting the action of the baths herein-
after mentioned.
Thus printed or marked, the plates are submitted to the action of a bath, which
will vary according to the nature of the metals; thus, for tinned iron the bath is
or may be composed as follows:-

page_text: And, having thus described and ascertained this Invention, I declare that I
claim,―
Firstly. The treatment or combined process of crystalized or crystal surfaces,
substantially as described.
Secondly. Printing on or otherwise marking crystalized or crystal-like surfaces,
as a preparatory process for the purpose set forth.
In witness whereof, I, the said Leon Quentin Brin, have hereunto set my
hand and seal, this Thirty-first day of December, in the year of our Lord
One thousand eight hundred and seventy-eight.
