I PERCIVAL PINCKNEY 151 Somers Road Southsea Hants. Mechanical
Engineer do hereby declare the nature of this invention to be as follows:-
The nature and object of this invention is for the facilitation of attack, during
marine warfare.
The special feature which is to be understood as constituting this invention, is
the utilization of chemicals of the nature of rocket composition, for the propulsion
of torpedoes, and also for the impelment of other devices which may come within
the description of submarine shells, or sea rockets.

COMPLETE SPECIFICATION.
Improvements in Torpedoes.
I PERCIVAL PINCKNEY 42 Hyde Park Road Southsea Mechanical Engineer,
late of 151 Somers Road Southsea Hants. 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 idea hereby protected as constituting this invention, is that of effecting the
propulsion of torpedoes, by means of the reaction, or recoil, that is produced by the
rapid escapement of gas,-or gases,-from a state of partial, or temporary
confinement.
My improved method for the propulsion of torpedoes, consists in the adaption
thereto, of a similar reactive force, as that by which impelment is given to war,
life-saving, and other aerial missiles known as rockets.
The way in which to accomplish my aforesaid method, is to fill a tube, or other
suitable receptacle with chemicals, which in regard to their reactive, or recoilative
force, are and shall be of the nature of rocket-composition.
Such composition may be compounded of any suitable chemicals, that is to say
of any chemicals that are capable by combustion, or otherwise, - of evolving gas
under a submerged, or other as may be required, alternative condition.
The said tube, or other suitable receptacle, is then to be inserted in, or attached
to whatsoever torpedo it may be designed to propel.
The propulsion of such torpedo is to take place upon, and in consequence of, the
liberation by combustion, or otherwise,-of the energy which shall be stored in
the rocket-composition, as before substancialy described.
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 I
claim is:
Claim 1. The sole and exclusive right, to propel torpedoes, by means of
chemicals that in regard to their reactive, or recoilative force, are substancialy of
the nature of rocket-composition.
Claim 2. The sole and exclusive right, to manufacture, to sell, and to supply,
torpedoes which shall be purposely manufactured, or purposely designed, or
purposely arranged for propulsion, in conformity with this invention.

page_text: Such manufacture, design, and arrangement, being claimed as constituting an
essential part, and feature, of this invention.
Claim 3. The sole and exclusive right to compound, to sell, and to supply, in a
tubular, or other suitable form, or forms, such composition, or compositions,-
as before substancialy described,-as may be during the existence of this Patent,
required for the propulsion of torpedoes.
Claim 4. That the term torpedo, shall cover such model, or toy torpedoes, as
are made in conformity with this invention for purposes of practice, or
amusement.
