A New or Improved Smokeless Explosive or Gunpowder.
We THOMAS HAWKINS, SAMUEL HENRY HAWKINS and HENRY HAWKINS
all of Lonsdale Villa, Green Street, Upton Park in the County of Essex Engineers
and THE DONNITHORNE GUN PATENTS AND AMMUNITION COMPANY LIMITED,
of 23 Coleman Street, in the City of London 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 :-
Our invention relates to the composition and manufacture of a new or improved
smokeless explosive adapted for use as gunpowder as well as for blasting and other
purposes where a powerful explosive is required.
In carrying our invention into practical effect, we proceed substantially as
follows:-
We take the undermentioned ingredients in about the proportions viz.,
The chlorate of potash, sugar and wood pulp flour or lamp black are first mixed
together. The bichromate of potash in a powder or liquid state is then incorporated
with the mixture and the whole mass well kneaded or mixed together. The
composition is then in the form of a thick paste, which is now granulated and
subsequently dried by hot air or by any other suitable means.
When the explosive is to be employed for blasting purposes or the like, the wood
pulp or lamp black is dispensed with, and an increased proportion of bichlorate of
potash is used in the mixture.
The explosive or gunpowder composed and manufactured as hereinbefore set
forth is adaptable for use with all kinds of small arms and ordnance for charging
shells or other projectiles and for blasting and other purposes.

The chlorate of potash sugar and wood pulp flour or lamp black are first mixed
together. The bichromate of potash is then incorporated with the mixture and the
whole mass well mixed together. If preferred the bichromate of potash may be
dissolved in water (in the proportion of 1 to 4 parts of bichromate of potash
1 to 4 parts of water) and the solution added to the other ingredients and the whole
mass well kneaded or mixed together: the composition is then in the form of a
thick paste which is now granulated and subsequently dried by hot air or by any
other suitable means. The former method is preferable when the powder is to be
employed for blasting or the like purposes and the latter method is preferable in
all other cases.
When the explosive is to be employed for blasting or the like purposes the wood
pulp flour or lamp black is dispensed with and an increased proportion of bichromate
of potash is used in the mixture.
The explosive or gunpowder composed and manufactured as herein before set
forth is adaptable for use with all kinds of small arms and orduance for charging
shells or other projectiles and for blasting and other purposes.
Having now particularly described and ascertained the nature of our said
invention and in what manuer the same is to be performed we declare that what
we claim is :-
1. The combination of the hereinbefore mentioned ingredients constituting an
explosive mixture in the proportions and for the purposes set forth.
2. As an ingredient in an explosive mixture the employment of the substance
known as bichromate of potash in a dry or liquid state.
