I PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent Agents do hereby declare the nature of
this invention to be as follows :-
This invention relates to the manufacture of an explosive compound for mining and
other purposes, and which is prepared as follows :
1. In a suitable vessel I heat by steam or otherwise, to a temperature of from
say 140° to 160° F. a quantity say for example, of forty pounds weight of Nitrate
of Potass, Nitrate of Lead, or Nitrate of Soda, or a mixture of these salts or of any
two thereof, the proportions in the latter case being varied according to the quality of
product required.
2. In a separate vessel I melt together, say four pounds of Naphthaline and two
pounds of Paraffin wax, and I incorporate this mixture with the Nitrate or Nitrates
heated as above, the whole being well stirred so as to thoroughly coat with the
Hydrocarbon the grains of the pulverized salt. I then allow the mass to cool,
stirring it occasionally to reduce it to a granular form.
3. The product of the above operation which is in itself inert, is rendere:
explosive for use by intermixture with about its own weight of finely pulverized
Chlorate of Potass.
The explosive compound thus completed may be used either in a free state or in
cartridges and be fired by means of an ordinary detonator.
In certain cases the Naphthaline and Paraffine of the preceding formula may be
replaced by some of the other solid Hydrocarbons, but without any practical advantage
so far as is yet ascertained.
The relative proportions of the different ingredients may be varied at will according
to the special qualities required in the product.
Dated this 24th day of September 1888.

COMPLETE SPECIFICATION.
An Improved Explosive Compound.
A communication from abroad by Louis FRAENCKEL, of No. 4, Arsenalsgatan,
Stockholm, in the Kingdom of Sweden, Banker.
I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent Agents, 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 an Explosive compound for mining and
other purposes, and which is prepared as follows:
1. In a suitable vessel I heat by steam or otherwise, to a temperature of from.
say 140° to 160° F, a quantity say for example, forty pounds weight of pulverized
Nitrate of Potass, Nitrate of Lead, or Nitrate of Soda, or a mixture of these salts, or
of any two thereof, the proportions in the latter case being varied according to the
quality of product required.
•
2. In a separate vessel I melt together, say four pounds of Naphthaline and two
pounds of Paraffin wax, and I incorporate this mixture with the Nitrate or Nitrates
Prica 71

page_text: heated as above, the whole being well stirred so as to thoroughly coat with the
Hydrocarbon the grains of the pulverized salt or, salts. I then allow the mass to
cool, stirring it occasionally to reduce it to a granular form.
3. The product of the above operation which is in itself inert, is rendered
explosive for use by intermixture with about its own weight of finely pulverized
Chlorate of Potash.
The explosive compound thus completed may be used either in a free state or in
cartridges and be fired by means of an ordinary detonator. It is of course preferable
to keep the coated Nitrates and the chlorates separated until it is desired to employ
the explosive.
In certain cases the Naphthaline and Paraffine of the preceding formula may be
replaced by some of the other solid Hydrocarbons such as resin, but without any
practical advantage so far as is yet ascertained. In the same manner; Nitrate of
Ammonium may be substituted or used in admixture with the other nitrates.
The relative proportions of the different ingredients may be varied at will according
to the special qualities required in the product.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed (as communicated to me by my
foreign correspondent) I declare that what I claim is :
The improved explosive composed of a suitable Nitrate cóited with hydrocarbon
and rendered active at the desired time by the admixture of an alkaline chlorate, all
substantially as and for the purposes set forth.
