Improvements relating to the Manufacture of Explosives.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the manufacture of explosives, and has for its object to
obviate as far as possible the dangerous secondary phenomena which still occur
more or less frequently with ignitions of explosives, for instance the formation of
pointed flames. As shown by trials the aforesaid object is realized by using in the
production of explosives containing nitre, for instance sodium, potassium, barium or
ammonium nitrate, as carriers of carbon particularly oxalates, tartrates, acetates
and hydrochlorates of the amido compounds of benzol, toluol, xylol and naphthalene
or their substitution products, which contain carbonic acid and hydrochloric acid at
the same time or only one of these acids partially or entirely formed.
It may be supposed that in this state the two acids counteract the before-
mentioned injurious secondary phenomena in a particularly favourable manner and
render their occurrence impossible.
For producing the explosives the neutral and acid salts and also of impurities of
these salts may be employed.
.
In the case of explosives which contain ammonium nitrate as a carrier of oxygen,
use is made of up to 8 per cent. of aniline acetate, 7.2 per cent. of naphthylamine
oxalate or up to 10 per cent. of aniline hydrochlorate. The two components are
mixed and further treated in the customary manner.
Dated this 12th July 1894.

Improvements relating to the Manufacture of Explosives.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent
Agents 45 Southampton Buildings, in the County of Middlesex, 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 relates to the manufacture of explosives, and has for its object to
obviate as far as possible the dangerous secondary phenomena which still occur
more or less frequently with ignition of explosives, for instance the formation of
pointed flames. As shown by trials the aforesaid object is realized by using in the

page_text: ammonium nitrate, as carriers of carbon hydrochlorates and carbonates of aromatic
amines separately or jointly. Such salts are particularly the oxalates, tartrates,
acetates and hydrochlorates, of the amido compounds of benzol, toluol xylol and
naphthalene or their substitution products, which salts contain carbonic acid in
half-ready state in the carboxyl (COOH) group and readily formed bydrochloric
acid in the HCl group.
In this state the said two acids counteract the before mentioned injurious
secondary phenomena in a particularly favorable manner and render their occurrence
impossible.
For the production of explosives of the hereindescribed kind the neutral and acid
salts may be employed. In producing such explosives the following procedure may
be adopted.
The aqueous solution of the above named amido compounds is added under
continuous stirring to the sodium, potassium, barium or ammonium nitrate
whereupon the whole mass is dissolved under application of heat. The solvent is
then removed from the mass by evaporation in the free atmosphere or in a rarefied
atmosphere and then the remaining explosive converted by suitable machinery into
the desired form. The production of the explosive may also be simultaneously
performed with the production of the nitre, particularly nitrate of ammonium.
In this procedure the calculated quantity of the amido compounds and acids is
added to the saltpetre-lye to be evaporated, whereupon the solvent is extracted in
the above described manner.
In the case of explosives containing nitrate of ammonium as a carrier of oxygen,
up to eight per cent. acetate of aniline, 7.2 per cent. oxalate of naphthylamine or up
to 10 per cent. hydrocblorate of aniline are employed as carriers of carbon. The
two components are mixed and further treated in the customary manner.
It should be well understood that the hereindescribed production of explosives
forming the object of the present invention maintains always the same character no
matter if hydrochlorates or carbonates are used jointly or each for itself as carrier
of carbon. In each case the novel characteristic of the production remains the
same viz. the employment of such bodies as carriers of carbon, which on ignition of
the explosive'instantaneously admit the generation of such gases in larger quantities
which are themselves incombustible and prevent the formation of pointed Hames by
suffocation.
Having now particularly described and ascertained the nature of the said.inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. The production of nitric explosives, by adding to the nitre a carrier of carbon
which consists of a hydrochlorate or carbonate of aromatic amines or a mixture of
hydrochlorate and carbonate or their substitution products, substantially as and for
the purpose set forth.
2. A nitric explosive containing as carrier of carbon a hydrochlorate or
carbonate of aromatic amines or a mixture of a bydrochlorate and carbonate or
their substitution products, substantially as and in about the proportions set forth.
