PROVISIONAL SPECIFICATION.
Improved Manufacture of Explosives.
I, MAX BIELEFELDT, of Wittenberg, Saxony, Doctor of Philosophy, do hereby
declare the nature of this invention to be as follows:-
Explosives to be employed in mines where the danger of ignition of fire damp
exists, have hitherto been inanufactured of Ammonium nitrate, with the exclusion of
potassium or sodium nitrates. I have however discovered that the disruptive force of
the explosive can be increased, without decreasing its safety against firedamp, if a
small portion of the ammonium nitrate be replaced by potassium nitrate. For this
purpose, according to my invention, I manufacture such explosives of a mixture
of ammonium nitrate, potassium nitrate, and resin, preferably in the following
proportions.

The manufacture of the explosive is effected as follows:-
The ammonium nitrate, potassium nitrate and resin are each separately pulverised,
and then mixed together; or all three ingredients can be pulverised together, thereby
at the same time mixing them. This intimate mixture of ammonium nitrate,
potassium nitrate and resin is then heated in suitable heating apparatus, preferably
closed, until the resin begins to melt, but without causing the mass to become liquid.
The cooled mixture is then ground in the usual manner and filled into cartridges.
Dated this 14th day of August 1896.

Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is
1. An explosive composed of a mixture of ammonium nitrate, potassium nitrate,
and resin, of which the ammonium nitrate constitutes the largest quantity
substantially as described.
2. Process for the manufacture of the explosive referred to in the first claim,
consisting in intimately mixing the pulverised constituents, and then heating the
same until only the resin begins to melt, without causing the entire mass to become
liquid, substantially as described.
