the Empire of Germany.
Sealed the 13th August 1878, and dated the 14th February 1878.
PROVISIONAL SPECIFICATION left by the said Fritz Viëtor at the Office
of the Commissioners of Patents on the 14th February 1878.
FRITZ VIETOR, of the Firm of Fritz Viëtor & Co., of 57, Aldersgate Street, in the
City of London. " IMPROVEMENTS IN THE MANUFACTURE OF AN IMPROVED COM-
POUND OR COMPOSITION FOR USE IN THE MANUFACTURE OF BUTTONS, STUDS, ORNA-
MENTS, FRAMES, AND OTHER FANCY GOODS." A communication from abroad by
Paul Artelt, of Berlin, in the Empire of Germany.
.
The object of this Invention is the production of a new or improved compound
or composition of a hard durable nature, and capable of receiving and retaining a;
high degree of polish, such composition being particularly applicable to the manu-
facture of fancy goods, such as buttons, frames for photographs, ornaments, such as
for dresses, imitation jewellery, pocket knife handles, and similar articles, such as
are now made from horn, bone, coal, jet, vegetable ivory, and so forth.
The following are the components :-
Coal tar pitch that is, the solid residues from the distillation of coal tar, which
is deep black and brilliant, without any resinous mixture.
Shellac, as ordinarily understood in commerce, which has great consistency and
firmness

page_text: Chalk, to increase the bulk and quantity of the compound, and temper it, and
this chalk is to be thoroughly dried, pure in quality, and finely powdered.
The proportions of the ingredients are,--
25 parts by weight of coal tar pitch,
10
65
ditto
ditto
shellac,
chalk.
These ingredients in the above proportions, and after having been thoroughly
ground and mixed, are placed in a boiler or retort heated up to about 100 degrees
Celsius, and are well stirred together until they become combined and incorporated
into a black lustrous mass, when it will be ready for use, and to be operated upon
in the press and dies, or moulds, in order to produce the desired forms by pressure;
and immediately after the pressing has taken place the surfaces of the articles will
become brilliant, lustrous, and hard when cool. The waste fragments from the
pressing can be re-heated and used up to the last particle.
For buttons made with shanks these said shanks are placed in the moulds or
recesses therein, and will be set immovably in the articles produced, and these will
never change or fade in color.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Fritz Viëtor in the Great Seal Patent Office on the 14th August
1878.

FRITZ VIETOR, of the Firm of Fritz Viëtor & Co, of 57, Aldersgate Street, in the
City of London. IMPROVEMENTS IN THE MANUFACTURE OF AN IMPROVED COM-
POUND OR COMPOSITION FOR USE IN THE MANUFACTURE OF BUTTONS, STUDS, ORNA-
MENTS, FRAMES, AND OTHER FANCY GOODS." A communication from abroad by
Paul Artelt, of Berlin, in the Empire of Germany.
The object of this Invention is the production of a new or improved compound
or composition of a hard, durable nature, and capable of receiving and retaining a
high degree of polish, such composition being particularly applicable to the manu-
facture of "fancy goods," such as buttons, frames for photographs, ornaments such as
for dresses, imitation jewellery, pocket knife handles, and such like articles, such as
are now made from horn, bone, coal, jet, vegetable ivory, and so forth, and for other
purposes and articles of ornament.
The following are the components:-
Coal tar pitch; that is, the solid residue from the distillation of coal tar, which
is deep, black, and brilliant, without any resinous mixture, or coal tar pitch in
mixture with white resin, or white resin alone.
Shellac, as ordinarily understood in commerce, which has great consistency and
firmness.
Chalk or plaster of Paris, or powdered glass, to increase the bulk and quantity
of the compound, and temper it, and this chalk or plaster of Paris is to be thoroughly
dried, pure in quality, and finely powdered.

page_text: Ine proportions of these ingredients are, for a good black composition,―
20 to 25 parts by weight of coal tar pitch or white resin,
10 to 15
70 to 60
ditto
ditto
shellac;
chalk or plaster of Paris.
For producing a colored or nearly white compound there is to be wholly or
partially substituted for coal tar pitch, white resin in the proportion of about 50 per
cent. of white resin to 50 per cent. of coal tar pitch, or from 50 per cent. to 100
per cent. of white resin to make up the proportion of 20 to 25 parts of this ingre-
dient to the compound, according to the color required; and for the production of a
semi-transparent compound, powdered glass may be substituted for a portion or the
whole of the third ingredient of chalk or plaster of Paris, in combination with the
white resin.
The ingredients in about the above proportions, and after having been thoroughly
ground and mixed, are placed in a boiler or retort heated up to about 100 degrees
Celsius, and are well stirred together until they become combined and incorporated
into a black or colored lustrous mass, which will then be ready for use, and to be
run into sheets for subsequent treatinent by heat and pressure, or be operated upon
in and subjected to the action of a press and dies or moulds in order to produce the
desired forms by pressure of the composition, and immediately after the pressing bas
taken place the surface of the articles will become brilliant, lustrous, and hard when
cool. The waste fragments from the pressing can be re-heated and used up to the
last particles.
The compound, as before stated, may be made into sheets of required thickness for
subsequent treatment in heated dies or presses.
For buttons made with metal shanks, or other articles with metal fittings, these
said shanks or fittings are placed in the moulds or into recesses therein, and will
become set immovably in the articles produced from the heated compound, and they
will never change nor fade in color.
Knobs or door handles, and furniture fittings, may be thus produced by placing
the metal parts, or backings, or framings, in suitably prepared moulds, and pressing in
the composition in a warmed or heated state into the moulds.
To ornament the articles any color in powder may be dusted on to or otherwise
applied, by painting, or otherwise, to the surface whilst warm, or gold or other
metallic leaf may be laid thereon, and then the articles are to be warmed and bo
pressed in heated moulds, which will set the pattern thereon indelibly, and produce
a polished and lustrous surface, the polish whereof will be heightened by simple
friction with soft inaterial.
Having now described the nature of the said Invention, and described the manner
in which the same is to be compounded and applied in order to carry the same into
practical effect, I claim the improvements in the manufacture of the improved com-
pound or composition, as and for the purposes substantially as specified.
In witness whereof, I, the said Fritz Viëtor, have hereunto set my hand
and seal, this Thirteenth day of August, in the year of our Lord One
thousand eight hundred and seventy-eight.
