Patent Agent in the city of Hamburg Germany for an invention of
IMPROVEMENTS IN THE TREATMENT OF FLOUR AND IN THE MANUFACTURE OF
ARTICLES THEREFROM a communication by Ferdinand Lange of Neumühlen
near Kiel in the kingdom of Prussia
PROVISIONAL SPECIFICATION left by the said Friedrich Hermann Felix
Engel at the Office of the Commissioners of Patents on the 20th March
1882.
FRIEDRICH HERMANN FELIX ENGEL Civil Engineer and Patent Agent the the
city of Hamburg Germany "IMPROVEMENTS IN THE TREATMENT OF FLOUR AND IN
THE MANUFACTURE OF ARTICLES THEREFROM a communication by Ferdinand
Lange of Neumuhlen near Kiel in the kingdom of Prussia
"
This invention which relates to improvements in the method of treating flour
made out of cerealia has for its object the manufacture of moulded or rolled articles
out of such flour. Such articles gain a stone-hard structure can be polished like
horn, vulcanized india-rubber or ivory and resist the influence of moisture to a
very high degree. At a temperature of about 100 degrees of Celsius such articles
or the substance treated after this method becomes plastic again and melts like
heated india-rubber.
By admixing colours with the material before pressing or rolling objects out of
it, articles may be produced of very different colours whilst without addition of
colours or other substance pure flour produces objects of more or less transparent
appearance
The method of treating flour after this improved mode is as follows:-
Flour is with the addition of water mixed to a paste which latter is in a heated
cylinder or trough under a temperature of about 140 degrees of Celsius kneaded
to a stiff cement like substance. This substance may be coloured by addition of
colours or it may be mixed up with plaster of Paris and many other materials and

page_text: is afterwards formed in metal moulds which are heated to a temperature of upwards
to 140 degrees of Celsius. The articles' thus formed are after being allowed to
cool off removed from the moulds. Instead of moulding articles as before described
articles can be produced out of the substance by rolling it between engraved or
otherwise prepared rollers which are heated to a high temperature.
The quality of the substance of getting plastic again at a temperature of
100 degrees of Celsius may be used for producing articles of a marbled appearance.
This is executed by forming plates or otherwise shaped blocks or bodies out of
differently coloured substance which plates, blocks or bodies are broken up and
parts of same are mixed up in heated moulds or between heated rollers in which
moulds or between which rollers the mixture gets plastic again and is compressed
into articles of a marbled appearance showing the different colours of all the
different coloured parts of which they are composed.

IN THE MANUFACTURE OF ARTICLES THEREFROM

Lange of Neumühlen near Kiel in the kingdom of Prussia
This invention which relates to improvements in the method of treating flour
made out of cerealia has for its object the manufacture of moulded or rolled articles
out of such flour. Such articles gain a stone-hard structure, can be polished like
born, vulcanized india rubber or ivory and resist the influence of moisture to a
very high degree. At a temperature of about 100 degrees of Celsius such articles
or the substance treated after this method becomes plastic again and melts like
heated india-rubber. By admixing colours with the material before pressing or
rolling objects out of it, articles may be produced of very different colours whilst
without addition of colours or other substance pure flour produces objects of more
or less transparent appearance.
The method of treating flour after this improved mode is as follows:-
Flour is with addition of water mixed to a paste which latter is in a heated
cylinder or trough under a temperature of about 140 degrees of Celsius kneaded
to stiff cement like substance. This substance may be coloured by addition of
colours or it may be mixed up with glue, plaster of Paris and many other materials
and is afterwards formed in metal moulds which are heated to a temperature of
upwards of 140 degrees of Celsius. According to the mixture or composition of
the material the temperature must be varied and under some circumstances a very
low temperature will prove sufficient. The articles thus formed are after being
allowed to cool off removed from the moulds. Instead of moulding articles as
before described, articles can be produced out of the substance by rolling it between
engraved or otherwise prepared rollers which are heated to a temperature the
height of which depends upon the mixture and which will readily be found by
observation and practical experiments during the operations.
The quality of the substance, of getting plastic again at a temperature of
100 degrees of Celsius, may be advantageously used for producing articles of a
marbled appearance.
This is executed by forming plates or otherwise shaped blocks or bodies out of
differently coloured substance which plates blocks or bodies are broken up and
parts of same are mixed up in heated moulds or between heated rollers in which
moulds or between which rollers the mixture gets plastic again and is compressed
into articles of a marbled appearance showing the different colours of all the
different coloured pastes of which they are composed.
Articles formed after this invention may be considerably strengthened by
moulding the composition onto the surface of paste-board, cloth, sheet-metal wire
gauze, or other resisting material. Or such material may be mixed up with the
composition, or layers of the material may be placed between layers of the com-
position and be moulded into same by outer pressure as before described.
Having now described the said invention in such wise that the same may be
carried into practice I claim:
Firstly. The method of treating flour prepared of cerealia for the purpose of
forming articles therefrom, by mixing up such flour with water, glue, plaster of
Paris, colours of different sorts or other suitable material to a stiff paste and by
forming such mixture in moulds heated sufficiently or between rollers as herein set
forth.

page_text: Secondly. The method of strengthening such articles by moulding the com-
position of flour and other materials herebefore described, on paste board, sheet
metal, cloth, wire gauze, or other suitable substance, or by moulding such material
between layers of the above composition as and for the purpose herein described.
In witness whereof I the said Friedrich Hermann Felix Engel have hereunto
set my hand and seal this twentieth day of September in the year of our
Lord one thousand eight hundred and eighty-two.
