Improvements in Explosives.
We, G. KYNOCH AND COMPANY LIMITED, and ALLAN THOMAS COCKING, both
of Lion Works Witton, in the County of Warwick, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to explosives principally intended for mining and other
blasting operation's.
Our object is to produce an explosive with a nitro glycerine basis, which
explosive will be powerful in proportion to its weight, and at the same time be
of the safety class incapable of igniting inflammable gases found in mines.
Our explosive consists of a mixture of purified nitro glycerine, barium or other
nitrate, wood meal, and aminonium oxalate, which is sometimes mixed with sodium
carbonate, and sometimes replaced by that substance.
Sometimes we also add sulphuretted bensol, and we incorporate the whole mass
uniformly to such character and consistency as to avoid any liability to the
exudition of the nitro glycerine.
In carrying our invention into effect in accordance with one mixture, for every
hundred parts of the finished explosive, we provide not more than twenty seven
parts, and not less than twenty five parts of thoroughly purified nitro glycerine,
together with not more than thirty-six parts, and not less than thirty parts of
barium nitrate; and not more than forty three parts, and not less than thirty
seven parts of thoroughly purified wood meal. To this mixture we add from half
a part to ten parts of neutral ammonium oxalate, or in place of the said oxalate,
or mixed with it we may substitute not more than half a part of sodium carbonate.
We may also add not more than half a part of sulphuretted benzol, and thoroughly
incorporate the whole in a manner well understood by manufacturers of explosives.
Our new explosive so produced is not liable to decomposition, and upon ignition
it explodes with a flame which is comparatively harmless, and is incapable of
igniting combustible gases found in mines.
Dated this 16th day of December 1896.

page_text: 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:-
Our invention relates to explosives principally intended for mining and other
blasting operations.
Our object is to produce an explosive with a nitro-glycerine basis, which
explosive will be powerful in proportion to its weight, and at the same time be
of the safety class incapable of igniting inflammable gases found in mines.
Our explosive consists of a mixture of purified nitro-glycerine, barium nitrate,
or other similar nitrate, wood meal, and ammonium oxalate or other similar
oxalate such as potassium, or sodium oxalate which is sometimes mixed with
sodium carbonate, and sometimes replaced by that substance.
We incorporate the whole mass uniformly to such character and consistency
as to avoid any liability to the exudation of the nitro-glycerine.
In carrying our invention into effect in accordance with one mixture, for every
hundred parts of the finished explosive we provide not more than twenty seven
parts, and not less than twenty five parts of thoroughly purified nitro-glycerine,
together with not more than thirty six parts, and not less than thirty parts of
barium nitrate; and not more than forty three parts, and not less than thirty
seven parts of thoroughly purified wood meal. To this mixture we add from half
a part to ten parts of neutral ammonium oxalate, or in place of the said oxalate,
or mixed with it, we may substitute not more than half a part of sodium carbonate,
and thoroughly incorporate the whole in a manner well understood by
manufacturers of explosives.
Our new explosive so produced is not liable to decomposition, and upon ignition
it explodes, with the production of a flame which is comparatively harmless, and
is incapable of igniting combustible gases found in mines.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :--
In explosives the combination with nitro-glycerine of barium nitrate, or other
similar nitrate, wood meal, and ammonium oxalate or other similar oxalate, with
or without the admixture of sodium carbonate, substantially for the purposes
described.
