I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows :-
The object of this invention is to provide for gelatinizing nitro-glycerine without
heating the same to a high temperature, solidifying the same at any degree at which
it will under ordinary conditions remain in the liquid state.
In carrying the said invention into practice, a quantity (up to say ten per cent)
of picric acid (trinitrophenol or trinitrophenic acid) is dissolved in the nitro-glycerine
to be gelatinized. With such solution is mixed or incorporated finely pulverized or
ground nitrated collodion cellulose in a quantity corresponding with the required
consistency of the jelly. The process of gelatinizing is accelerated by frequent
stirring or agitation of the mass.
The quantity of picric acid to be added depends upon the quantity and quality of
the nitrated cellulose employed, and upon the degree of consistency of the jelly to be
obtained. The gelatinizing process will be effected in a longer or shorter space of
time according to the quality of the nitrated cellulose.
The jelly thus produced serves as an explosive either pure or mixed with suitable
additional substances.

1, HENRY HARRIS LAKE, of the Firm of Haseltine Lake and Co. Patent Agents
Southampton Buildings in the County of Middlesex 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 :-
The object of this Invention is to provide for gelatinizing nitro-glycerine without
heating the same to a high temperature, solidifying the same at any degree at which
it will under ordinary conditions remain in the liquid state.
In carrying the said Invention into practice, a quantity (up to say ten per cent) of
picric acid (trinitrophenol or trinitrophenic acid) is dissolved in the nitro-glycerine
to be gelatinized. With such solution is mixed or incorporated finely pulverized or
ground nitrated collodion cellulose in a quantity corresponding with the required

time according to the quality of the nitrated cellulose.
The jelly thus produced serves as an explosive either pure or mixed with suitable
additional substances.
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 foreign
correspondents I declare that what I claim is
The process of gelatinizing nitro-glycerine with nitrated cellulose by means of an
addition of picric acid (trinitrophenol or trinitrophenic acid) substantially as and for
the purpose specified.
