PROVISIONAL SPECIFICATION.
Improvements in Explosive Compounds.
I, JOSEPH SAYERS, of Ardeer Factory, Stevenston, in the County of Ayr, North
Britain, Chemist, do hereby declare the nature of this Invention to be as follows, that
is to say:
My said Invention has for its object the making of improved explosives suitable
for various purposes, and not liable to explode undesignedly or accidentally.
In carrying out my Invention I employ nitro-benzene, or other suitable nitro-
derivative of a hydro-carbon, or a suitable mixture of two or more of such substances,
the same having been gelatinised, by the admixture there with of a suitable nitro-
cellulose; and I combine a nitrate or mixture of nitrates with the gelatinised nitro-
substance. For some special purposes a small proportion of nitro-glycerin may be
combined with the other ingredients.
The nitrate or mixture of nitrates is added in the form of a fine powder and is
thoroughly mixed or incorporated with the gelatinised nitro-substance in proportions
which will vary with the particular ingredients employed. Thus for example 6 parts
by weight of nitrate of ammonia may be combined with 1 part of a gelatinised
nitro-substance consisting of crude nitro toluol having combined with it 4 per cent.
of nitro-cellulose; or 3 parts nitrate of potash may be combined with 2 parts of a
gelatinised nitro-substance consisting of crude nitro-benzene having combined with it
8 per cent. of nitro-cellulose.
Dated this Twenty-sixth day of November 1888.

Improvements in Explosive Compounds.
I, JOSEPH SAYERS, of Ardeer Factory, Stevenston, in the County of Ayr, North
Britain, Chemist, 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, that is to say :-
My said Invention has for its object the making of improved explosives suitable
for various purposes, and not liable to explode undesignedly or accidentally.
In carrying out my Invention I employ nitro-benzene or other suitable nitro-
derivative of a hydro-carbon, or a suitable mixture, of two or more of such substances,
the same having been gelatinised by the admixture therewith of a suitable nitro-
cellulose; and I combine a nitrate or mixture of nitrates with the gelatinised nitro-
substance. For some special purposes a small proportion of nitro-glycerine may be
combined with the other ingredients.
parts
The nitrate or mixture of nitrates is added in the form of a fine powder and is
thoroughly mixed or incorporated with the gelatinised nitro-substance in proportions
which will vary with the particular ingredients employed. Thus for example, 4 parts
by weight of nitrate of potash may be combined with 2 parts nitro-benzene or
nitrate of potash with 2 parts binitro-benzene; or 4 parts nitrate of potash
with 2 parts nitro-toluene; or 34 parts nitrate of potash with 2 parts binitro-toluene ;
or 4 parts nitrate of ammonia with 1 part binitro-benzene; or 5 parts nitrate of
ammonia with 1 part binitro-toluene, the nitro-substance having in each example
combined with it with the aid of heat if necessary a suitable proportion of nitro-
cellulose, which may vary from 2 to 10 per cent. in different cases. The proportions
specified of the nitro-derivatives, are suitable for what are commercially known as
nitro-derivatives of benzole and toluole.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Forming explosive compounds by combining one or more suitable nitrates with one
or more nitro-derivatives of hydro-carbons gelatinised by means of a suitable
nitro-cellulose, substantially as hereinbefore described.
