Complete Specification Accepted, 16th Nov., 1888
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 to be as follows:-
In the Specification to iny application for a Patent dated 29th March 1887 No. 47.13
(being a communication from my said correspondent) was described the manufacture
of explosive compounds that give no flame on explosion, consisting of the admixture
of oxalic acid or of salts thereof to explosive compounds containing nitro-glycerine,
nitro-cellulose, nitro-benzole, nitro-toluol or nitro-naphthaline, and it was stated that
to these inixtures may be added a suitable carrier of oxygen.
According to the present invention I produce an effective and comparatively cheap
explosive compound which explodes without flame, and which is not hygroscopic, by
adding to the above mentioned mixture of an explosive nitro-compound and oxalic
acid or salts thereof, a large proportion of potassium nitrate.
The proportions of the three ingredients may be variously modified according to the
nature of the substances employed, the compound which employ by preference being
composed as follows:-
Dinitro-benzole
Potassium-nitrate
Ammonium-oxalate
-
20 parts by weight.
-
SO parts by weight.
-
10 parts by weight.
The proportion of ammonium oxalate in the above described compounds may vary
between 5 and 12 per cent of the weight of the other two ingredients combined.

Improvements in Explosive Compounds.
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

The proportion of ammonium oxalate in the above described compounds may vary
between 5 and 12 per cent of the weight of the other two ingredients combined.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I claim is :—
An improved manufacture of explosive compounds consisting of the combination
of oxalic acid or salts thereof with explosives containing nitro-glycerine, nitro-
cellulose, nitro-benzole, nitro-toluol, or di- or tri-nitro-naphthaline, and with a large
proportion of potassium nitrate, substantially as herein described.
Dated this 13th day of October 1888.
