I, OSCAR LINDNER, of 21, Wielandstrasse, Nuremberg, in the Empire of
Germany, Merchant, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the manufacture of matches the
object being to produce non-poisonous and scentless matches which can be ignited
by striking or rubbing on any surface when intentionally done, but which cannot
easily be ignited accidentally by rubbing together, as when in boxes or cases.
The match is so constructed that unless the end or point itself is rubbed or struck
it cannot be ignited.
According to this invention the match head is made of a low explosive sub-
stance or mixture with a cap or point of highly explosive mixture so that it can
be ignited by striking or rubbing the end, but if the side or head proper only
is rubbed no ignition takes place so that the matches are safe when packed in
boxes or cases.
In manufacturing such a match its head is made enlarged and covered with a
feeble or low explosive mixture composed of water with 6 parts of chlorate of
potassium, 2 parts of sulpheret of antimony, 1½ parts of gum, and 1 parts
pulverized clay or amber.
After drying, the tip of the match is dipped into another mixture con-
sisting of water and milk and 6 parts of phosphorus, 2 or 3 parts of chlorate
of potassium, 1 parts of dextrine, and 14 parts of aniline.
The phosphorus and chlorate of potassium give a very high explosive combina-
tion to which the nitrogeneous milk and aniline act as reductive means.
This mixture forming a little cap on the head of the match, easily catches fire
by being rubbed on any surface and carries the explosion to the feeble or low
explosive mixture covering the head of the match and which inflames the
wood.

ascertained in and by the following statement:-
This invention relates to improvements in the manufacture of matches the
object being to produce non-poisonous and scentless matches which can be ignited
by striking or rubbing on any surface when intentionally done, but which cannot
easily be ignited accidently or by rubbing together, as when in boxes or cases.
The match is so constructed that unless the end or point itself is rubbed or struck
it cannot be ignited.
Such being the nature and object of my said invention, the following is a
complete description of same.
According to this invention the match head is made of a low explosive sub-
stance or mixture with a cap or point of highly explosive mixture so that it can
be ignited by striking or rubbing the end, but if the side or head proper only
is rubbed no ignition takes place so that the matches are safe when packed in
boxes or cases.
In manufacturing such a match its head is made enlarged and covered with a
feeble or low explosive mixture composed of water with 6 parts of chlorate of
potassium, 2 parts of sulpheret of antimony, 1 parts of gum, and 1½ parts
pulverized clay or amber.
After drying, the tip of the match is dipped into another mixture con-
sisting of water and milk and 6 parts of phosphorus, 2 or 3 parts of chlorate
of potassium, 1 parts of dextrine, and 11 parts of aniline. The phosphorus and
chlorate of potassium give a very high explosive combination to which the nitro-
geneous milk and aniline act as reductive means.
This mixture forming a little cap on the head of the match, easily catches fire
by being rubbed on any surface and carries the explosion to the feeble or low
explosive mixture covering the head of the match and which inflames the
wood.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is—
(1) A match, the head of which is made of two parts, one part being highly
explosive, the other less explosive, as and for the purpose herein described.
(2) A scentless non-poisonous match having an enlarged head of low explosive
mixture tipped with a high explosive mixture as and for the purpose herein
described.
