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:-
The
The Invention is for propelling steam vessels. By Reciprocating Internal
Plungers 2. worked by an Engine, in cylinders. 1. are fitted to the ship as shown
on the Drawing filled with my Provisional Specification the said cylinders 1 opening
directly at their outer ends through the skin of the vessel to the external water.
positions of the cylinders 1 shown are for going ahead or astern; to enable the vessel
to be propelled ahead or astern those at the stern of the vessel in the longitudinal views
being for propelling the vessel ahead and the others reversely placed being for pro-
pelling it astern by the reciprocation of the plungers in the cylinders. In going ahead
the Plungers used for propelling the vessel astern are disconnected from the Engine
and in going astern the plungers for propelling the vessel ahead are disconnected by
By means of a clutch the go ahead when the Plungers are then put in motion and as
they reciprocate in the cylinders by the outward thrust sufficient resistance is obtained
by the expulsion of the water from the open outward ends of the cylinders to impart
motion to the vessel in one or the other direction according to which of the plungers are.
reciprocated. Sluice valves 3. are fitted at the external ends of the cylinders 1.'to prevent
access of water to the ship if the Plungers should be taken out for repairs. If con-
sidered necessary external sluices may be fitted to stem or centre cylinders to be under
the control at the Engineer.
The plungers may be of any diameter or any stroke and may be worked together or
alternately to turn the vessel or propel it ahead or astern.
The
In the Drawings referred to the top longitudinal section and the corresponding cross
sections beneath shew cylinders and plungers at the stern for propelling the ship forward
and other cylinders and plungers amidships for propelling the ship astern-The two lower
Figures are a plan and longitudinal section with cylinders and plungers at the stern and
amidships as before and with additional cylinders and plungers at the stem.
cylinders here shewn at the stem and stern are horizontally placed instead of inclined.
4 are cylinder covers for giving access to the cylinders. 5 are air holes for the inlet and
escape of air at the rear of the plungers, and 6 are doors for the air supply; 7 are
drain cocks for draining the cylinders. All these may be of any ordinary or well known
construction.
N°4 The feature of novelty claimed is the Propelling of vessels by Internal
Reciprocating Plungers, working in cylinders open at their outward ends and com-
municating through the skin of the vessel directly with the external water substantially
as hereinbefore described and illustrated by the Drawings accompanying my Provisional
Specification.
No 2 these 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.
