PROVISIONAL SPECIFICATION.
New or Improved Explosive Compositions.
I ERNST VON BRAUK of Boppard am Rhein in the Empire of Germany no
occupation do hereby declare the nature of this invention to be as follows:-
This invention consists in new or improved explosive compositions formed by the
addition to chlorate of potash of substances hereinafter described to form explosive
compounds suitable for shooting and for blasting purposes.
For shooting powder,
to the chlorate of potash is added a mixture of fatty oil with litharge or hydrate
of protoxyde of manganese and for blasting powder a mixture of re-in with a
decoction in water of a gun giving plant such as carraghen moss althee würzel or
the like.
These are compounded as follows. To 100 parts by weight of chlorate of
potash are added 40 parts of boiled linseed oil and 15 parts of litharge or the
same quantity of hydrate of protoxyde of manganese. These are well kneaded
together, the excess of oil removed by pressure between blotting paper and the
mass finely ground, dried and broken to size.
To form a blasting powder. To 100 parts by weight of chlorate of potash are
added 15 parts of American resin and sufficient carraghen gum or its equivalent to
make the mass into a stiff paste. This paste is then treated in the same manner as
that above described.

COMPLETE SPECIFICATION.
New or Improved Explosive Compositions.
I, ERNST VON BRAUK, of Boppard am Rhein in the Empire of Germany,
Gentleman, do hereby declare the nature of this 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 has reference to the manufacture of new or improved explosive
compositions suitable for ordnance and for blasting purposes by the addition to
chlorate of potash, of certain substances hereinafter described. For ordnance
purposes there is added to the chlorate of potash a fatty oil and litharge or
hydrated protoxide of manganese, and for blasting purposes there is added to
chlorate of potash a mixture of resin with a decoction in water or vinegar of a
gum-giving plant such as carraghen moss, althee würzel, gum tragacanth or the
like.
An explosive composition suitable for ordnance purposes can be made as
follows: To 100 parts by weight of chlorate of potash are added 40 parts of
boiled linseed oil and 15 parts of litharge or the same quantity of hydrated
protoxide of manganese. These substances are well kneaded together, the excess
of oil removed by pressure between blotting paper, and the mass finely ground,
dried and broken to size.
Or about 1000 grammes of chemically pure chlorate of potash may be intimately
mixed with about 100 grammes of linseed meal and about 60 grammes of old
linseed oil varnish, and the mass kneaded with about 200 grammes of vinegar or of
water containing about 2 grammes of gum tragacanth. The cake of composition
thus obtained is then rolled, dried, and granulated. The dry powder prepared in

page_text: this manner is subsequently mixed or turned gently without pressure and then
further dried in the air, preferably in the sun. A drier should be added to the
linseed oil varnish to make it dry quickly. An explosive substance suitable for
blasting purposes is made as follows:-To 100 parts by weight of chlorate of
potash are added 15 parts of American resin and sufficient carraghen gum or its
equivalent to make the mass into a stiff paste. This paste is then ground, dried,
and broken to size in the same manner as the composition first hereinabove
described.
Or about 1000 grammes of chemically pure chlorate of potash may be intimately
mixed with about 150 grammes of incense or American or other resin, and the
mixture kneaded with about 2:0 grammes of vinegar or of water containing about
3 grammes of gum tragacanth, and the mass or cake thus obtained is then ground,
dried, and granulated as before.
The powders or compositions prepared as hereinbefore described are not hygro-
scopic, and their manufacture is dangerous only to a very slight extent, as they
burn but slowly and do not readily catch fire in the open air. When however they
are confined as is the case when being used in mines for blasting purposes, or
in a gun, their explosive force is very much greater than the best black gun-
powder.
My improved explosives are especially suitable for use in mines because they do
not produce dangerous and noxious gases.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed declare that what I
claim is:
1. The manufacture of the herein described new explosive consisting of chlorate
of potassium, to which has been added a fatty oil such as herein referred to, and
litharge or hydrated protoxide of manganese substantially as herein set forth.
2. The manufacture of the herein described new explosive consisting of chlorate
of potash to which has been added a resin such as referred to, and a vegetable
mucilage substantially as herein set forth.
