Complete Specification Left, 18th Oct., 1890-Accepted, 4th Apr., 1891
PROVISIONAL SPECIFICATION.
An Improved Method and Apparatus for Propelling Vessels.
ROBERT MORRIS, Engineer, 3, Millicent Terrace, Gateshead-on-Tyne, do hereby
declare the nature of this invention to be as follows:-
1
An improved system for propelling ships submarine boats torpedoes and small
boats by the system of cylinders, plungers, air, and valves. Cylinders and plungers
can be fitted to the stern, and stem or sides of the vessel as desired, the cylinders
opening at their outward ends through the skin of the vessel directly to the external
water. Into these cylinders are fitted reciprocating ram plungers worked by engines,
and small boats or life boats can be worked by hand power.
Cylinders and plungers may be any size as desired. The plungers may be hollow
with ends within them these ends to have holes through them to admit tubes through
for air to pass through the tubes to the water. At the ends of the tubes valves may
be fitted as desired, and at the inner ends of the cylinders valves are fitted as desired
to admit the air into the cylinders to pass through the tubes to the water. Provision
is made for the examination and repairing of the plungers by inserting a sluice
valve in the cylinders which prevents access of water into the ship. An external
covering can be fitted over the stem or side plungers to provide for an even run of
water over these portions when they are not working.
The feature of novelty claimed is the propelling of vessels by reciprocating
plungers in cylinders, air, and valves, as here inserted.

COMPLETE SPECIFICATION.
An Improved Method and Apparatus for Propelling Vessels.
ROBERT MORRIS, Engineer, 3, Millicent Terrace, Gateshead-on-Tyne, 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 :-
An improved system for propelling ships submarine boats torpedoes and small
boats by the system of cylinders, plungers, air and valves. Cylinders and plungers
can be fitted to the stern and stem or sides of the vessel as desired, the cylinders
opening at their outward ends through the skin of the vessel directly to the
external water. Into these cylinders are fitted reciprocating ram plungers worked
by engines, and small boats or life boats can be worked by hand power. Cylinders
and plungers may be any size as desired, the plungers may be hollow with ends
within them, these ends to have holes through them to admit tubes through for air
to pass through the tubes to the water. At the ends of the tubes valves may be
fitted as desired, and at the inner ends of the cylinders valves are fitted as desired
to admit the air into the cylinders to pass through the tubes to the water, sub-
stantially as described and illustrated by the drawings accompanying my Complete
Specification; cylinders, A, are fitted through the skin of the vessel, plungers, B,
reciprocating to the external water; tubes, C, are through the plungers; valves, D,
are at the ends of the plungers to let air out when the plungers are coming inwards;
valves, E, are to let air into the cylinders when the plungers are going outwards;
Section No. 1, cylinder and piston, F, are for pressing the air through the tube, H,
into the cylinder, A. Section No. 2, the cylinder larger than the plunger, B.

page_text: By that means there is sufficient air to be pressed through the tube, C, when the
plunger is coming inwards; provision is made for the examination and repairing of
the plungers by inserting a sluice valve in the cylinders which prevents access of water
into the ship. An external covering can be fitted over the stem or side plungers to
provide for an even run of water over these portions when they are not working.
All things in here are to be the same as in my Provisional Specification.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is -
The feature of novelty claimed is the propelling vessels by reciprocating plungers
in cylinders, air and valves, as here inserted..
