An Improved Combustible Compound or Fuel.
I, DAVID DUNCAN ESSON, of 30, Sharsted Street, Kennington Park, in the county
cf London, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to a combustible compound or fuel capable of burning in
a closed chamber without the addition of air and if desired in contact with water
and of giving off large volumes of gas at considerable pressure.
My improved compound contains nitro-glycerine, dry gun cotton, vaseline and
camphor.
In practice I have found it advantageous to mix these ingredients in the
following proportions, viz.
Nitro-glycerine 55 parts by weight
Dry Gun cotton 30
Vaseline
Camphor

10 do.
5 do.

do.
In combining these ingredients I prefer to intimately mix the nitro-glycerine,
gun cotton and a portion of the vaseline and to use the other portion of the
vaseline and the camphor as a coating for the other part of the compound which
is preferably made up in the form of rods and placed in tubes or the like with the
extra camphor and vaseline around it.

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to a combustible compound or fuel capable of burning in
a closed chamber without the addition of air and, if desired, in contact with water,
and of giving off large volumes of gas for maintaining a high pressure.
My improved compound contains nitroglycerine, dry guncotton, vaseline, and
camphor. In practice I have found it advantageous to mix these ingredients in
the following proportions, riz.: nitroglycerine, fifty-five parts by weight; dry

in the manner described or in connection with the apparatus herein referred to.
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 1
claim is:-
1. The improved combustible compound or fuel consisting of nitroglycerine, dry
guncotton, vaseline and camphor in substantially the proportions stated, and
mixed or combined substantially in the manner described.
2. The hercin-described combustible compound or fuel consisting of nitro-
glycerine, dry guncotton, and vaseline mixed together and coated with a mixture
of vaseline and camphor, substantially as described.
3. As a new article of manufacture, the herein-described combustible compound
or fuel consisting of nitro-glycerine, dry guncotton and vaseline mixed together
and formed in sticks or rods, said sticks or rods being coated with a mixture of
vaseline and camphor, substantially as described.
