I do hereby declare the nature of this invention to be as follows:-
My method is as follows.
Cylinders are fitted to the stern and stem or centre of the vessel as desired; into
these cylinders are fitted reciprocating ram plungers, P, worked by an engine or
engines; when the vessel is requised to go forward the centre or stem plungers
are disconnected; and the stern plungers put in motion; the inward stroke of the
ram it is follow up by the body of water, which when being displaced by the
outward thrust of the rams imparts motion to the vessel; to go astern, the aft
plungers are disconnected, and the centre or stem plungers put in motion; provision
is made for the examination, and repairing of the plungers by inserting a sluice
valve close to the mouth of cylinders which prevents access of water into the ship,
for more safety a water tight bulkhead with covers may be fitted at forward side
of cylinders as shown on drawins marked, K. An external covering can be fitted
over stem or side plungers to provide for an even run of water over these portions
when they are not working.

I do hereby declare the nature of my invention for AN IMPROVED SYSTEM FOR THE
PROPULSION OF STEAM VESSELS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My method is as follows;
The
Cylingders are fitted to the stern and stem or center of the vessel as desired the said
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, P, worked
by an engine or engines the said plungers being of a size such that when they are in their
retracted position they fill or practically fill the cylinders to the exclusion of water.
plungers may be hollow drums as shewn clearly in the upper cross-sections on the
drawings accompanying my Provisional Specification. When the vessel is to go
forward the center or stem plungers are disconnected, and the stern plungers put in
motion. The inward stroke of the ram it is followed up by the body of water, which
when but not so as to enter the cylinders and when the water is being displaced by the
outward thrust of the rams impurts so that they protrude from the cylinders motion is
imparted to the vessel. To go astern the aft plungers are disconnected, and the center
or stem plungers put in motion. Provision is made for the examination and repairing
of the plungers by inserting a. sluice valve close to the mouth of cylinders which
prevents access of water into the ship; For more greater safety a water tight
bulkhead with covers may be fitted at the forward side of cylinders as shown on the
aforesaid Drawings marked, K. 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 Invention is for Propelling Steam Vessels by reciprocating external
plungers, P, worked by a steam engine, Cylinders, D, are fitted to the ship as shown
on the Drawings filled with my Provisional Specification. The positions shown are for
going ahead or astern. When going ahead the plungers for propelling the vessel
astern are disconnected from the engines bey means of a clutch. The go ahead
. plungers are then put in motion, and as they reciprocate in and protrude from the
cylinders in their outward thrust sufficient resistance is obtained to impart motion to
the vessel.

page_text: The plungers may be any diameter or any stroke and may be worked together or
alternately to turn the vessel or propel it ahead or astern. I do not claim under this
Patent internal plungers or pistons acting as described in the Specification of my
Patent No. 2583 of 1886.
No The feature of novelty claimed is the propelling of vessels by reciprocating
external plungers, which, as they are reciprocated in cylinders protrude therefrom and
act directly upon the water externally to the skin of the vessel substantially as described
and illustrated by the Drawings accompanying my Provisional Specification.
No The plungers may be any diameter or any stroke, and may be worked
together or alterative to turn the vessel or propell it ahead or astern.
