Improvements in the Manufacture of Explosives.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings,
Chancery Lane, in the County of London, Chartered Patent Agent, do hereby
declare the nature of this invention (as communicated to me from abroad by
Frederick William Slack, of Johannesburg, in the South African Republic, South
Africa, Artist and Photographer,) to be as follows:-
According to my invention I produce an explosive by mixing together chlorate
of potash, paraffine-wax and wood charcoal. The proportions in which these
ingredients are employed are preferably as follows:-
:―
90 parts of chlorate of potash,
4
6 parts of paraffine-wax
parts of wood charcoal
These ingredients are mixed together as follows.
The chlorate of potash and wood charcoal are cach thoroughly ground to a
fine powder and are then mixed together and heated to a temperature of about
110° Fahr.
The paraffine wax is then melted and thoroughly mixed with the heated mixture
of chlorate of potash and wood charcoal. The resulting compound, which is highly
explosive on percussion or detonation, is then compressed into cartridges or other
convenient form for use. This explosive compound can be used for any of the
purposes for which other explosives are now used.
Dated this 5th day of August 1898.

Improvements in the Manufacture of Explosives.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings,
Chancery Lane, in the County of London, Chartered Patent Agent, do hereby
declare the nature of this invention (as communicated to me from abroad by
Frederick William Slack, of Johannesburg, in the South African Republic, South
Africa, Artist and Photographer), and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:—
According to my invention I produce an explosive by mixing together chlorate

page_text: of potash, paraffine-wax and wood charcoal. The proportions in which these
ingredients are employed are preferably as follows; —
-
90 parts of chlorate of potash
6 parts of paraffine-wax
4 parts of wood charcoal
These ingredients are mixed together as follows.
The chlorate of potash and wood charcoal are each thoroughly ground to a
fine powder and are then mixed together and heated to a temperature of about
110° Fahr.
The paraffine wax is then melted and thoroughly mixed with the heated mixture
of chlorate of potash and wood charcoal. The resulting compound, which is highly
explosive on percussion or detonation, is then compressed into cartridges or other
convenient form for use. This explosive compound can be used for any of the
purposes for which other explosives are now used.
It has the advantage of being waterproof so that it is not damaged by exposure,
and can be exploded under water.
It can be handled and transported without danger, being capable of being
heated to a temperature somewhat higher than 150° Fahr. without exploding,
and no deleterious gases are evolved on its combustion or explosion.
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 consisting of chlorate of potash, paraffine wax and wood charcoal
combined substantially in the proportions and in the manner set forth.
Dated this 6th day of January 1899.
