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 my application for Letters Patent No. 14412 of 1885 I
described an improved explosive compound termed "Amide powder" in which salts of
ammonia were mixed with saltpetre and charcoal in such proportions as, on combustion,
to produce an explosive amide compound. According to the present invention an
explosive compound suitable for blasting purposes is produced by mixing with the
above mentioned Amide powder either nitroglycerine, guncotton, or other similarly
constituted nitrated body, whereby a compound is produced that is similar in its action
to dynamite, but has the advantage over this that it is capable of being ignited at low
temperatures by means of an ordinary percussion cap, while at the same time it burns
without residue and produces no deleterious gases.
The proportions which it is preferred to employ in preparing this compound are,
from about 40 to 60 parts by weight of the Amide powder with from 60 to 40 parts of
nitroglycerine, the parts being simply incorporated in the ordinary way.

An Improved Explosive Compound for 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 statement :-
ແ
In the Specification to my Patent No. 14,412 of 1885 I described an improved
explosive compound termed Amide powder" in which salts of ammonia were mixed
with saltpetre and charcoal in such proportions as, on combustion, to produce an
explosive amide compound.
According to the present invention an explosive compound suitable for blasting
purposes is produced by mixing with the above mentioned Amide powder either
nitroglycerine, guncotton, or other similarly constituted nitrated body whereby a
compound is produced that is similar in its action to dynamite, but has the advantage
over this that it is capable of being ignited at low temperatures by means of an
ordinary percussion cap, while at the same time it burns without residue, and produces
no deleterious or obnoxious gases.
The proportions which it is preferred to employ in preparing this compound are,
from about 40 to 60 parts by weight of the Amide powder with from 60 to 40 parts of
nitroglycerine.
The Amide powder described in the said Patent No. 14,412 of 1885 is for the
purposes of this invention by preference prepared with 48.5 parts by weight of Potash
Saltpetre, 38 5 parts of Ammonia Nitrate and 13 parts of charcoal, these being mixed
together in a powdered state. To this mixture is mixed the nitroglycerine or other
nitrated body, as before described being simply incorporated by stirring.
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 :-
An explosive compound consisting of a mixture of about 48.5 by weight of Potash
Saltpetre 38-5 parts of Ammonia Saltpetre and 13 parts of charcoal, to which mixture
after incorporation is added nitroglycerine or other analogous nitrated body, in the
proportion of from 60 to 40 parts of the latter to from 40 to 60 parts of the former.
