I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane,
in the County of Middlesex, Consulting Engineer and Patent Agent do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improved explosive compound for guns or fire arms
and blasting purposes, similar to ordinary gunpowder, in which, in place of the
sulphur, an ammonium salt is employed in combination with saltpetre in such
proportions that on ignition potassamide is formed, a compound consisting of
explosive potassium nitride and ammonia, which is volatile at high temperatures
and which increases the useful effect of the explosive, and burns without residue.
The composition and action of this explosive, which is termed "Amide powder "
is expressed, for example in the application of nitrate of ammonia, by the formula:
K NO, H. N (NO₂) + 3 C = KH₂ N + H₂ O + CO + 2 (C NO₂).
The amide KH, N is potassium nitride combined with ammonia, for:
3 (KH, N) = Kg N + 2 Hg N.
The explosive material, prepared in the proportions here given, which are always
determined for the formation of amide, and which material is not hygroscopic, has
the following advantages:
1-The action of the powder is increased by the explosive potassium nitride.
2-It burns without leaving any residue.
3-It produces no gases that are injurious to the gun.
4-The smoke is much less than with ordinary gunpowder.
The manufacture of this amide powder is otherwise just the same as that of
ordinary gunpowder, and therefore requires no essential alterations of the
apparatus employed for ordinary sulphur gunpowder, the cost of manufacture
being also not greater.

page_text: In place of ordinary saltpetre other salts of similar action such as have been used
in the manufacture of gunpowder may be employed, and also in place of nitrate of
ammonia, other ammonia salts may be used for the production of the explosive, as
long as care be taken that the composition is such as to produce amide compounds
in its combustion.

An Improved Explosive Compound for Guns or Fire Arms and 1
Blasting Purposes.
I, CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane
in the County of Middlesex, Consulting Engineer and Patent Agent 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 1
statement:-
This invention relates to an improved explosive compound for guns or fire arms
and blasting purposes, similar to ordinary gunpowder, in which, in place of the
sulphur, an ammonium salt is employed in combination with saltpetre in such
proportions that on ignition a compound of potassium, nitrogen and hydrogen, 2
termed potassamide, is formed which is volatile at high temperatures, and which
increases the useful effect of the explosive, and burns without residue.
The composition and action of this explosive, which is termed "Amide powder"
is expressed for example in the application of nitrate of ammonia, by the formula:
K NO, + H. N (NO₂) + 3 C = KH₂ N + H₂O + CO + 2 (C NO₂).
The Amide powder made according to this formula would consequently consist
of 101 parts by weight of saltpetre, 80 parts of nitrate of ammonia, and 40 parts
of charcoal.
;
The explosive material, prepared in such proportions as are here given, which
are always regulated to determine the formation of amide, and which material is
not hygroscopic, has the following advantages.
1. It leaves very little if any residue when burned.
2. It produces no gases that are injurious to the gun.
3. The smoke is much less than with ordinary gunpowder.
If other ammonium salts are employed in place of the nitrate, the formula given
above will vary in accordance with the salt employed, and, from the composition of

page_text: this the proportions of the several ingredients can then be readily determined in a
manner well understood.
The manufacture of this amide powder is otherwise just the same as that of
ordinary gunpowder and therefore requires no essential alterations of the apparatus
employed for ordinary sulphur gunpowder, the cost of manufacture being also not
greater.
In place of ordinary saltpetre other salts of similar composition and properties
such as have been used in the manufacture of gunpowder may be employed, and
also in place of nitrate of ammonia, other ammonia salts may be used for the
production of the explosive, as long as care be taken that the composition is such
as to produce amide compounds in its combustion.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it to be
understood that I do not claim generally the use of ammonium salts for the
production of explosive compounds, as I am well aware that this has already been
done, but not in combination with such ingredients and in such proportions, as to
produce an explosive amide compound on combustion, but what I claim is :-
The manufacture of an explosive compound consisting of charcoal, saltpetre or
its equivalent, and an ammonium salt in such proportions that on ignition
volatile and explosive amide compound is formed, substantially as herein described.
